[HOT!]Charging problems, false drain readings, dialer issue, battery life, SOLUTION

Hey guys,
I would like to make your situation easier, so you don't have to read like 1000s of forum threads to get information I'm giving you here. These are the issues I faced with my incredible s, and the so called solutions.
The device:
Stock EU htc incredible s/ htc droid incredible 2 on Gingerbread. NO software mods at all.
According to my knowledge the same applies to the htc desire s and the htc desire hd as well. Most of these problems come forward after updating to gingerbread. If you are still on froyo, I wouldn' recommend updating.
1st issue. High standby drain.
According to Currentwidget and battery monitor my incredible s doesn't have lower battery consumption in standby than 38Mah.
Solution:
Drain readings are corrupted, there is a bug involved.
In reality You only have around 5-6Mah drain in standby.
Proof.
Left phone in standby for 2 days without messing with it, ended up with 40% left.
So if you have a minimum of 40Mah drain for two days. (48hours x40Ma=1920Ma) The battery's capacity is no more than 1500Ma, so it's obvious that standby drain readings are corrupted.
IGNORE drain readings!
2nd issue: You take it off the charger and it's 95%
Some say that phone charges till 100% than shuts charging down till battery reaches 90%, than charging starts again.
Some say our Lithium battery cannot get charged till 100% which is normal. This is the reason our device doesn't show % in notification area.
Solution: Ignore battery monitor, use inbuilt battery charge indicator, and be happy.
If you want to test battery life, start test at 90% and your test won't be corrupted.
3rd issue: Dialer using too much battery.
This might to be a bug as well. Still to be confirmed. The dialer doesn't use that much of power it only gets stuck in built in battery use indicator giving false drain data.
Some say it doesn't stop using proximity sensor after being in a call, hence the big drain. Incredible s's proximity sensor is visible during call, check it in the dark, it blinks. After call it stays inactive. So the dialer using it 24/7 seems to be a false statement.
4th issue: Declining calls in pocket.
When taking or declining a call, you swipe vertically on the screen. If you have your phone in your pocket with the screen facing your body, you can easily take or decline some calls when pulling out. This is more likely if you have a pocket made of thin material.
Solution: Put your phone in your pocket with the battery cover facing your leg. Don't worry about bumping into like a table corner and smashing your screen. Our gorilla glass is almost indestructible. Using a pouch or cover does the trick as well.
Not sure why htc is so obsessed with the vertical answer procedure. With horizontal swipe we wouldn't have this problem and users have been complaining about this since the desire came out.
5th Issue: Wifi disconnects when signal low, but still would be fine under froyo.
Connection gets disconnected when signal is 86db or lower.
This is a gingerbread related problem, htc cannot do anything about it.
No solution just yet.
For those who complain about battery life, I am on gingerbread with loads of apps installed and with very heavy use 3hours of display, wifi, skype,internet browsing I can use the phone for 12 hours. With moderate use min 2 days.
Battery saving tipps:
-Don't let google and htc sync. It uses lot of data and battery resources.(I don't like my sensitive data to be copied on their servers anyway.) Sync with your pc regularly.
- If u use data for e-mail and weather sync, use Gsm only mode, you don't need that much of speed for those, turn WCDMA on if u need it for skype, etc. Hspda and 3g are big battery killers.
-Everything on manual sync. There is a sync all widget in sense to use. U can hit it anytime you want to.
-No live wallpaper
-Hotspot uses excessive amount of battery. Use it on charger only.
-Screen light to be turned down. Use Screen filter app nighttime.
-Turn wifi and mobile data off when not in use, so phone can sleep properly. (wifi timeout app)
-Turn off wireless network positioning.
-Keep bluetooth off when not in use.
-Select short screen timeout like 15s.
-Screen on time is the main culprit in appalling battery life. Use your watch to check time rather than turning the screen on.
-If u struggle to find 3g or Hspda for data or network itself, change provider, because no matter what phone u have, u will have this problem. Try to find spots in your flat with better signal for data. Searching for network uses a lot of battery.
-Try to charge your phone from 0% overnight with the phone off for a couple of times (8-12hrs)
-When gps is on it doesn't mean that it uses battery. If you see the sattelite icon blinking or just on, that's when it uses battery, a significant amount of battery.
-Consider buying the official extended battery available in US (droid incredible 2 2100Mah), coming to EU soon. I wouldn't recommend buying the unofficial ones just now.
Obviously if you apply some of these battery life will be better. If you apply all of them, battery life will be exceptional.
Hope I helped.
Have fun guys!

Hi!
Thanks you for this! I buy my incredible s a couple of days ago, upgraded instantley. I met most of these problems and now I am happyer with my phone knowing these.
Could you give link to the battery you wrote about???

i appreciate what you're trying to do - but if you are going to follow all those steps you might as well have bought a nokia 3210
"Use your watch to check time rather than turning the screen on"
i mean.... really??

As I said, you don't have to follow all the steps.
You might face conditions when you need every drop of your juice, so it's good to know how to get the most out of your battery, isn't it?

It's for the droid incredible 2, but thats equivalent to Incredible s.

Sorry if this seems sarcastic, but if you're gonna buy a smartphone and turn everything that makes it a smartphone off, then save yourself a few hundred quid and buy a Nokia 1100
I use mine to sync everything and anything I want, and don't worry about it, as long as it lasts the day, which it does, I'm happy.

you misinterpreted what the op said. He is just stating what you could do if you found yourself in a situation where you had to maximize battery usage. Obviously most of us are around an outlet or usb plug most of the day so that we can charge the phone often.
Thanks for the info OP. I just wish that current widget would show us the right info. Or some other app :/

Thanks for the info OP. My buddy has had endless problems with his Incredible. I'll Chrome to Phone this thread and send it to him!

Its not the apps fault, the phone just reports wrong. So any other app should also fail.
@superman, perhaps a faulty app is causing the problems

Wifi issue should be resolved with the ota update.
However there is a network at my workplace which I couldn't connect to. I guess it is some kind of wifi repeater, it doesn't look like an actual wifi router. There is no cable connecting to it. Apparently I can connect but I get 0 signal next to it. Others can connect with full signal. Any idea?

It is FAR from "almost" indestructible. Some people also say it's impossible to scratch it, yet mines been scratched (this AND nexus one) It's nice glass but indestructible? I think not, not even "almost"
Oh the guy above me also had his cracked!

Live wall papers do eat your battery, but it's almost close to nothing. I've read that whatever uses more than 2% of your battery will be displayed in the "battery usage" I've used live wallpapers and it's never even shown that. (I think it also depends on what kind of wallpapers you use though.. let's say you had one that interacted with you) perhaps that might drain more battery.. but who turns on their phone to play with their wallpaper lmao
I've tested and disabling google sync barely makes a diff. I also don't think it uses a lot of data. I don't completely disagree with you though, manual sync is probably a better idea. On the other hand, I don't really think Hspda/3g are big battery killers, I notice that if you use the browser, the battery drops quick. Let's say you used "gsm" / "2G" and the webpage takes longer to load whereas 3G would have it loaded within seconds.. Which would waste more battery? I'm not 100% sure but I'd say just keep 3G and turn on 2G if you're not doing anything else with your phone. To my surprise, 2G is horribly slow.

Completely false. This is only a cover on top of your screen. It doesn't change the power being outputted to the screen. If you look at what RogerProdacter is making, you'll see that he's trying to modify the phones brightness output.

Disagree again. It's really up to user though, that's insane. I'd be pissed if my phone kept shutting off in 15s! What you can actually do is turn off the phone yourself or get something like Lock screen widget which instantly turns off your screen. Two reasons it's better - You don't have to worry about the timeout - you shut it off sooner than 15s.

I don't know what kind of world you live in, sounds way too good to be true. Just instantly change providers eh? Where I live.. that's not really easy to do. I'm sure most people getting cell phones would have enough common sense to pick something that works in their area anyway.

JuiceDefender

I've noticed a pretty big difference in battery life and charge time with this application running. The application states that it has improved battery life by 1.75x on my phone. It also seems to lop some charging time off.
Sent from my VS910 4G using XDA Premium App

same here, its actually increased my batter life by 2.3x but thats because I put in in constant extreme mode. It saves a ton of battery but because it shuts everything off except texting and calling while the screen is off, when I turn it on to get the text or call it blows up with emails and other notifications... Its kind of funny actually. But yeah this is a great app if your looking to conserve life as long as possible and not worried about getting delayed notifications.

good stuff. i have mine set to aggressive and it's done ok for now.

I think my biggest problem with juice defender is the learning curve. Yeah I want to save battery life. But no, I don't want to miss an IM or email or something. I keep looking for a generally simple walk through on how to set stuff up and select the settings to get the best optimal results.
I have an extended battery and 2 of the regular ones, so battery life has ceased to be an issue. Still I'd like it to be a bit better than it is now.

WWJDD?
I use aggressive on mine and it says that it averages x1.83, it's amazing, I'm actually considering buying the paid version because of how awesome it really is, and that's from someone who has had a Droid for over 2 years and has never paid for a single app, because I thought that it was pointless. Thank you for converting me JD!!!

Here's a good place to start reading up on features http://latedroid.com/juicedefender
When you're ready to roll aggressive/custom you can take a look through the settings / help, also this app configuration article on their FAQ looks handy as well http://feedback.latedroid.com/forums/70437-general/suggestions/1409997-faq-configure-apps?ref=title
The auto config is fine but to see some real benefits one needs to set it up. Over time I'm sure the battery life benefit is huge.
For example you could disable data during the night, set it to 15 minute data off during the day, configure the apps you want (i.e. disabling data when using a game that doesn't need it).
My main concern is regarding compatibility with the Revo.
For example I'm getting an error that says: "ROM is not compatible with AOSP helper (3G control is unavailable) - get CyanogenMod"
Not sure how much of the app is compatible, what have you guys found?

JD set on balanced. 52 sms messages, multiple facebook checks, nothing else. good 4g coverage. unplugged at 9am, 30% and falling at 3pm. ok?

check how good your service is. when it's not the data draining bettery, it usually means it's spending a lot of energy searching for cell signal

pro mode/off topic:
Root and use SetCPU, and slam into 'on demand' with a minimum of 250mhz clock. battery life is CRAZY good now and i never have to worry about missing a email from gmail or my works outlook server (which goes off like crazy, around 100 emails a day)

Pointless to buy apps? lol, thats the reason many app developers won't develop for Android. Android owners are generally known to be cheapskates, and this is why the big app developers have avoided Android for the most part. There not going to develop something if they don't think they can make money on it. And that is the biggest reason the iPhone gets the best apps and we get leftovers. The other reason is the amount of different Androids, but the main reason is that they want to make money because they are a business.

I actually bought the most expensive of this app, I think it was $5 or $6, my buddy has the itouch and he hacked it, he now can have pretty much any app he wants for FREE. The only things I used my original Motorolla Droid was for taking pictures (stock app), playing angrybirds, and calling/texting people. With this new phone I'm doing a lot more, and very willing to give credit where credit is due, so get off your high horse and buy an iphone if your so worried about getting the bad end of the deal.

I bought JD Ultimate. Great buy IMHO. I was using set CPU and Setting Profiles which work well. JDU does all that those do and so much more. I have on demand CPU set. wifi only comes on when I am home based on cell signal GPS not the standalone GPS which chews battery. It also lets you disable individual apps from checking statuses when the screen is off and then enables them as soon as you turn the screen on. GPS standalone only comes on when the screen is on. I have different profiles for work hours and off hours so it does email instantly while at work and only every 15 minutes in the evening. I have more than doubled my battery life.
Revo + De-crap rom + lock scree/battery indicator mod + Juice Defender Ultimate = best phone available today

lag to re-enable mobile data?
i stopped using JD because I couldnt take the lag and inconsistency with which it would restore mobile data connection on unlock
i tried restoring a backup of JD beta and it actually seems to be more consistent.
i'm curious, how long does JD ultimate take to restore data connection for those who have it?
thx

5 seconds... Maybe 10 if I'm in a bad coverage area. This is 3g only though. No 4g here yet.
Sent from my VS910 4G using XDA Premium App

It does take a few seconds to restore connections. And it is a little annoying. Probably 5 seconds for everything to be restored and 100% functioning.
With Ultimate version you can make very detailed customization's. So for example you could tell it not to give access to apps like Facebook to update when the screen is off, and to only turn on Wifi when at a certain GPS location (it uses phone radio for location not the GPS radio so it doesn't use battery), and use processor on demand scaling, and you could set it to only turn off radio's during off hours, say in the evening when the 5 second lag might not be as big an issue. Doing those things would still give you significant improvements in battery use while not causing the hassle of waiting for radio's to turn back on. For example I have mine set to sync email in real time during business hours, and at 15 minute intervals in the evening. So I don't get as much battery life as I potentially could, but I also don't have to wait for it to sync things up while I'm at work.
Right now I have been off the charger for 6.5 hours, and have been checking email regularly, and even flashed the clock mod that just got posted in the development forum, and I'm at 80% battery. Not bad.

Doubt he is "hacking" them. There is installius for the iPhone which is the apparently store cracked equivelant which houses many already cracked ipa's. With that being said many developers are in arms in apples lack of piracy for not checking having a more consistent way of checking authenticity of applications. As long as it keeps up you will see less updates for popular applications and developers moving to different platforms.

Hello all,
I like to use "Green Power Free" for battery savings. You can download it in the market. It's a free app, i suggest it to all my Android friends.

Now I'm going to have to go back on saying green power. It fails to register the lock/unlock correctly and either never shuts down the modems on a screen lock or never turns them back on after an unlock. Green power works well on my friends Streak and on another friends inc2, so must be the LG magic getting things fuzzy for GP. So back to JD for now.

Droid 4 battery issues...unbearable.

I spent a few hours looking through other threads, but nothing seemed to quite fit my scenario.
Stock droid 4 with the latest over the air update.
I use the phone very sparingly during the day, and my battery drains very quickly...
Usually take off the charger around 8am and battery is below 20% by 2pm.
My usage is usually one or two 5 minute calls, and probably 10mins of facebook.
Is there a good smart action I could try?
I had one that turned off the 4g while the screen was off, but it made sending picture messages unbearable...
My battery use indicator blames screen, then OS, then facebook....
I feel as if it's not reporting the culprit correctly...
Any help is much appreciated.

I've had similar issues, not sure what I did to cause them. When I first got the phone, 16hrs+ with what I would consider moderate usage was normal. I've flashed AOKP and the battery life is back to normal (on track for 15hrs today), but the stock rom is a disaster.
I'll let you know what I turn up (if anything), but I have a feeling I'll probably be wiping everything out since I actually like the stock ROM (plus no hw accel in ICS).
Edit: Also, how did you have a smart action turn 4G on/off? I was under the impression we can't control that at all, except via system menu. Is a downside to VZW's 4G...

I believe that was actually via the app Juicedefender.
even with it on i was still only getting about 8 hours...
I am semi interested in rooting/flashing a rom etc, but my last experience there was a disaster(thanks to a ****ty droid eris)

I disabled all widgets except for facebook, being that it's the only one I use...
The only non essential apps running all the time are battery circle, and facebook(widget i guess?)
I'm now charged to 100%, gonna see where these changes take me.

What are your settings as far as Brightness, Haptic Feedback, Screen Timeout, Vibration (Incoming Message/Call or End Call). Also, I recommend just using the FB app instead of the widget as I notice most of the widgets draw power even when the screen is off.
I am currently running Eclipse 1.3.7 w/ xrjxMod, Brightness all the way down, all vibration and haptic feedback is off. Since I am rooted I also used ROM Toolbox to adjust my scan interval to the minimum. I have the screen timeout to the max, but I always turn it off manually after use. I am constantly on either FB, XDA, txt messages or the occasional game/Netflix use and with the exception of watching a full episode or movie on Netflix, I am averaging about 6 to 8 hours on a full charge.

My battery is now sitting at 46%.
Since my last post I used the phone for 18mins of phone calls and nothing else.
The breakdown is 46% voice, 23% android OS, 12% display, 9% phone idle, 8% cell standby...
The brightness is as low as possible, haptic feedback is off, phone is set to vibrate(thats the only way I get calls)
All three location settings are on....Should I turn them all off? I dont know which are important...

I agree with azreal. Check your setting. Haptic feedback sucks up juice and unless you like it is more of an annoyance imo. There is an option for it in language and keyboard as well as in the screen menu for your soft keys.
Do you have your gmail setup to constantly sync? If its not needed un-check it in you accounts menu.
Are you leaving wifi on when your not in range of a remebered router?
If you are not in a strong 4g area set it to cdma only in your wifi and networks menu.
My opinion of apps to extend battery life is a negative one. Its an app that always runs to make things stop running???? Some work ok but most do not.
If all else fails I would suggest the eclipse rom for the d4. As long as you are safestrapped and follow directions properly you can't go wrong. In the case of a bootloop shut the phone off and reboot and you will come back to the recovery screen to try it again or go back to stock. Its nearly foolproof.
You may also want to do a battery stat wipe if your still having issues. Just discharge your phone completly, then fully charge wipe stats and completly discharge again then fully charge once more, and see if you notice a difference.
I get around 15-16hrs on stock and up to 22hrs on eclipse (varies with usage) by following these few things.

I would hazard a guess that having 4G on all the time is one of the main culprits. I leave 4G off unless I am browsing the web, forums, or something else where the extra speed is nice. I use the 4G Toggle widget from the market to turn 4G on and off. I always turn it off before hitting the power button to turn off the screen. No need for it to be sucking juice when I'm not actively using my phone.

I just installed the toggle switch, I'm gonna give it a go.

To turn off the gmail sync go to accounts click on you tap the account. Then uncheck the sync box.
When you want to check your email go to the gmail app hit the menu and sync. Takes about 30 seconds extra but saves some battery.

I'm always skeptical when people blame gmail sync or 4G on battery issues. When the phone was new on stock, and on ICS now, I have three gmail accounts, a yahoo account, and one Exchange account all syncing in the background + 4G on 24/7 and getting around 16hrs of battery life. This was the case for weeks. Then I started having trouble with Verizon's Backup Manager, did a factory reset, and now stock battery life is ~ 8hrs, with 4G OFF
I'm thinking at the very least, there is an issue with the stock battery information panel. My feeling is it hides battery use by the stock bloatware...

I agree that there is probably more to it than just 4G or syncing. Especially where people are getting only 8 hours or so battery life. I personally have noticed definite battery savings with 4G toggled off when not in use though. I can usually still go most of the day even with it toggled on all day but with 4G off, except when I actually need it, I usually get to bed with 30% - 40% battery left as opposed to 10% - 20% left with 4G on all day.

I would also turn all 3 locations off. No need to run the gps when not using navigation. I keep my 4G on as I use it frequently but I am going to try the toggle as well for the extra savings on battery when not netflixing/browsing.

Yep. I'm also having big issues with my Droid 4 battery. First I thought it was the firewall. But even after uninstalling the app, the drainage is absurd. The battery drains so fast, the phone gets warm.
I don't know where to look. I read something about logcat in another thread but could't find it anymore.
My Droid 4 can work about 5 hours on one battery charge. No gps, no 4g and no wifi. If I turn on wifi, it lasts about 8 hours, so I'm suspecting that some process loops when in non WIFI mode.

If you're out of options try using an app called watchdog. It let's you see if there is an app that's draining your battery unusually fast.

Thanks for the tip. But what whatchdog should I use? There are many apps called watchdog

Watchdog task manager lite (free version).

I tried that this morning. Still poor battery life on stock, but watchdog doesn't flag anything. Very weird
Oh well, I would definitely recommend AOKP for anybody having battery problems.
For me today: 4 hours 55 minutes since unplug, 80% left.
Screen time on: 50 minutes (!)
That being said, I do keep my screen on pretty low. Still, you can tell I've been using it...

Watchdog couldn't help me but. My data monitor showed that motorola.services was generating a lot of data the past few days (800+ MB :O ) and responsible for the battery drainage. I blocked it with droidwall. It's better now, but sometimes it still pops up and generates data despite the fact it's blocked.
So glad that I have an unlimited internet plan or else I was really screwed

How's everyone's battery life?

So how's everyone's battery life on the HD? I've gotten about 11 hours average with decent usage, but I instilled Juice Defender and I'm getting about 20 hours now or so. Noticed better battery life on the One X but that's probably just because the One line from HTC has incredible standby time.

Charging takes FOREVER.
10-15 hours for me without Juice Defender. I played Gun Bros Multiplayer for 1.5hours and the battery was almost dead. My Atrix 2 could play for 2.5 hours. So the Atrix HD dosent have the greatest battery life. I see it lasting with mid-heavy use just for the work day at a 9-5 job then having to recharge it. My Atrix 2 with juice defender lasted well into the next day.
I cant say I'm too happy about that, but at least overall the phone is an improvement over the Atrix 2 except for battery life.

I can usually go thru a whole day on a full charge. It won't do 2 days.

Poor battery and camera are the only things keeping from trading my GS 3 for this phone.

I'm getting between 10-12 hours with screen brightness on medium, normal usage, and good signal. It's definitely better than what I'm seeing on my VZW Gnex on JB.

I am getting decent battery life I'm at about 50 with 6 hours of pretty heavy use. Getting LTE too in some spots. So I know that is heavier on battery buy otherwise I am happy. I am sure it will calibrate too after time

Everyone who has the Atrix HD should have an app called "SmartActions"
It contains a battery extender. I've been using it next to juice defender and it's working really well.
I've been playing games, running lookout mobile on my phone, and watching movies on my SD card.
I used it heavy all night and drained it to 40%
Let it sit off the charger and woke up to 35%
Used it Heavy (Games&and 45min Video) from 9am till 11:54am Drained it to 28%
The battery extender app under Smart Actions and Juice Defender vastly improved my battery performance. I feel it's on par with the Iphone battery life, if not better.

i think battery life is super. i went from arix 4g to this. sucks i cant pull battery though, i had 3 extra batteries for my atrix 4g

Eventually one of those case companies like PowerSkin will make a case that doubles as an extended battery.
From my understanding the case plugs into the USB port so you dont have to swap the battery.
I'm keeping my eye out for one, but its too soon to expect them being sold right now.

Some of you are too critical. Battery life is amazing. How long you want it to last? As near to forever as possible?? Its an Android with a long life!!!

Quick question for Atrix HD users can you turn off LTE mode via *#*#4636#*#* like could with Atrix 4G?

I waited a couple days before judging so it could recharge a few times and I wouldn't playing with it all the time!
It seems to run down very quickly when the screen is on - even though I have brightness turned down most of the time. It needs a charge about the time I get home from work, whereas my Captivate still had a good charge and could make it through the night and to work the next morning with room to spare. I'm doing the same basic things I did on my Cappy - just checking email occasionally, gReader a couple times, FB a few times.
I'm hoping it improves a bit over time. I have already activated the battery saver SmartAction and just installed JuiceDefender today.
I tried the LTE mode code above and it didn't work. I tried an app that should change the setting and it didn't work either. I tried creating a new APN and it won't stay on it, just switches back to the default AT&T APN. Guess we'll have to wait for root.

I just got this a couple hours ago. Will have some battery info on it tomorrow if it stays in my possession.

You must have got lucky with your Captivate, because mine would burn through 30% batter in idle after 4 hours,
Smart Actions and Juice Defender seem to do the trick.
I found that Widgets and some games (especially gameloft games) will keep the phone from going into deep sleep. I know that the game "Gun Bros" sends notifications to your phone and randomly will do background syncing.
Also making sure that you completely exit apps helps tremendously with battery.
Here is a good artical about saving battery life. It's worth the read even if it might be a little old:
Top 10 Battery Saving Tips For Android

I dont know how you guys are getting battery life that good. I made the mistake of charging myphone only halfway on the first day after it died. But I've been trying to cycle it properly since.
But I cycled my phone twice today. Battery life is complete crap.
My day today:
I woke up at 5:45, played Cordy Sky for 30 minutes and checked all my stuff. On wifi the whole time. Battery was down to 82%.
Commuted to work, 1.5hrs. Listening to music from SD card for most of it. Had LTE on for most of the ride, 30min of the ride is underground, data off. 73% by the end of the ride.
My office has virtually NO service, LTE or otherwise, I couldnt even make a call. I also didnt get on wifi for about 2 hours. My phone was at 25% by 11am.
At which point i just ran it on full brightness, screen on, wifi off, syncing, etc until it died so I could cycle it.
I'm lucky to get 6 hours out of it.
I am using tons of the Smart Actions. Turning on wifi when I get home & get to work. All the "extender" settings are activated and ready.
--
Doesnt Juice Defender counteract the Smart Actions? Are you using the free versions, or ultimate?
--
Lastly, we, as smartphone users, shouldnt have to sacrifice functionality to save battery time. That's just a fact, and manufacturers are doing something wrong by not fixing that. The article you linked to asks too much of the user, basically turning the phone into a "dumb phone" until you activate everything again.
I even have smart actions doing some of those things, but still... wtf?

Smart Actions and Juice Defender work great together. Mind you that juice defender takes a day or two to learn your phones habbits.
Honestly I'd check your apps and see what services they are running and disable them. Not a lot of apps were made or updated for ICS yet, so you'll find a few here or there that will stop your phone from going into sleep.
If your battery life gets worse, I'd go get it checked out. My first Samsung Captivate battery held a weak charge, then all of a sudden the charge died. AT&T replaced it for me.
I felt the same way you did the first day I owned the phone. Once I got things setup right, it's been a dream. Honestly no, I havent lost any function out of my phone. I just learned some new habbits... like closing out of apps completely. Turning my screen of instead of letting it time out. ect..

Yep.. scanning for signal is probably the biggest battery killer you could have.
Honestly I'd just put my phone into sleep mode until I was in an area with service.

thanks guys, i'm getting slightly better battery life.
I'll post a screenshot of my battery levels graph when it gets lower later today. I installed Juice defender after getting to a full charge (chargin while off) at 1am. Went to sleep, and it didnt lose too much in the next several hours. which was nice.
right now, at work, w/ no service, but I'm on wifi and I'm not in airplane or sleep mode, it's lasting pretty evenly.
To me, it seems like the screen is the BIGGEST battery suck. I've noticed that every time my graph dips rapidly, it's when the screen is on. I dont think the brightness can be turned down enough. And I tend to check my phone a lot.
I imagine a bugfix in the future, which will adjust the way the screen uses power, but right now, combining screen & lte use basically murders the phone.
Someone else mentioned they played a game for 1.5 hours and the phone was almost dead. There's definitely something bad happening with screentime being proportionate to battery.
Note the correlation in the image
It starts at 1am, the drop in the middle is 5:30am, when my alarm went off for almost 45min and I didnt wake up.
The next major drop is my 1.5hr commute. But I was streaming video this time for 3/4th of it.
Then I got to work.
(((((I'm not really complaining anymore at this point, i know I've gotta tweak my usage, and let the tools figure out the battery, as well as let the battery itself figure out my usage better.... in due time it'lll get better. Now I'm pretty much just trying to share information w/ interested parties))))

Try putting the phone in airplane mode, then going into settings and turning wifi back on when you are in a place with no cell service. It'll turn off the cell radio but let the wifi one work.

'How To Get Better Battery Life' tips and tricks

I haven't seen one of these threads yet, and I think it will benefit users of our D4 forum.
If you have any tips/tricks, feel free to add them here.
My first tip: TURN OFF 4G AT ANY TIME POSSIBLE. 4g is a battery vacuum.
Sent from my DROID4 using xda app-developers app

Here's the biggest....Widgets and Social Networks.
Watch your widgets (weather, news, facebook, etc..) that update/refresh. Most will allow you to adjust the refresh time. Set it high or to manual refresh.
Social Networks.....set them to refresh only. You don't need them refreshing their data in the background, just have them pull the latest down when you are actually using them (Facebook, Twitter, Google +, etc..). Set to manual refresh so that they only refresh when you are using the app. You don't need the latest status messages your friends are posting hitting your phone when it's in your pocket.
WiFi and. 3G/4G.....if you are in a location that makes your phone drop/search for signal and WiFi is available....use WiFi. The constant searching/seeking and establishing a 3G/4G network connection will kill your battery faster than having a constant 4G connection. This leaves the cellular band free for calls and all your apps that sync/pull data from the internet can happily run over the WiFi connection instead of killing your battery.

I second this, keep your widgest, number of home screens, and social networking apps down. Phones haven't reached the point of being able to be computers quite yet. Here are some apps to keep it snappy though:
Fast Reboot (by Great Bytes Software)- same as a battery pull without having to. Clears up a lot of RAM.
Lte On/Off - with this, you can switch to 3G (CDMA) only, and have it set to automatically default to that setting in the case of you switching to airplane mode for some reason. But it does reset the app if you turn of your phone. Fast Reboot doesn't clash with this app.
App Cache Cleaner - clears out a lot of the cache you otherwise would have to go to Manage Applications to clean out.
That's all I can think of at the moment for non-rooted users. I won't go into rooted b/c this is not the right place. But here are a few battery saving settings:
GPS - have only the Google one on, it's the fastest in my experience.
Display - have it set to the lowest setting when at all possible. Only lowers color distortion in my experience.
Developer optionss - go in here and turn on the force GPU settings. This may not be the case with everyone, but it gives my phone a little more zip and makes things smoother.
Apps (this is the very bottom of the developer settings) - Adjust these to your liking. Perhaps try setting the max number of backgrounded processes to 4.

I wonder how it looks on you ...
on my droid 4 and with Jelly Bean i lost ~5,5% battery by hour no matter what i do even on airplane mode.. still aroud 5% by 1h
please can you advice how its look from your side ?

I had the same thing with my Droid 4. I finally sbf'd it, and reinstalled everything one at a time. This fixed it.

Is there any way for the Droid to use only 2G networks? 3G/4G while idle seems to be the biggest battery drainer.

Same here. In a couple cases its just made it worse. I will be trying out the extended battery in a couple weeks though. Hopefully it'll let me go at least a day without charging.

Making it better
The Droid 4 firmware just isn't very battery friendly... and it's not a new phone so your battery probably isn't either. Two things to consider.
LiIon batteries lose capacity over both cycles (cycling losses) and time (calendar losses.) If your battery is 18 months old and was charged nightly, you've lost 25% or more of the life anyhow... much more if the phone was kept plugged in after the charge and ran warm. And the drop accelerates with more cycles. It may be time to change the battery.
Adding JuiceDefender ( I use Ultimate) triples my battery life even in basic mode.
Replacing the battery is really simple; buy one from Amazon, open the back, carefully pry out the old one (it's held down by a double-sided tape), unscrew the connector (very small Torx, but jewelers screwdrivers work), swap and reassemble. $30 later (and a few hours to charge), you have your capacity back.

yeah after trying juice defender for about a month or so i noticed my phones battery life extend much more. so i opted to buy the ultimate juice defender and sure enuff more battery life... i am very pleased with this app. however if in the future i do want to extend the battery a lil more, then i will purchase a brand new battery and then replace the old one...

Turning off auto sync, turning off WiFi while on 4G works. Also make sure there's not any apps running in the background. Being root, there's apps you can download to close any open app

with CM it is an easy to safe much energy! and if you really want to do this on a right way, you really need to own a rooted system....
1. underclocked my cpu for 200mhz, dont have to comment.... if you use lightweight lounchers and care for background apps, it will noprob
2. use only 2g-networks, those are more available than every other networks, and even tcp/ip works with it, for whatsapp etc it is way enough bandwitch
very important!!!!
3. check your internal recievers after installing an app!! with "autorun manager" on a rooted device you can uncheck every function from every app, even autostart of an already killed facebook app, or statistical functions from apps which comes with most of them
4. get your brightness automated, if it is dark, you can automatically safe energy by a automatically regulation
5. maybe you would prefer to deactivate vibrations/haptic feedback/call vibration completely, its very energy consumpting.....
6. deactivate the gps-reciever complete, and just turn it on if you need it
7. set your display timeout as less than possible for your behaviour, 15 seconds may be enough
8. know what runs in background, evrything in background, sucks energy.....
9. deactivate nfc
10. deactivate bluetooth
with this i get a standby about ~1-3 days! and if im phoning and writing to much maybe not fully to one day. if i watch now on my energy tables, my display is consumpting still 40-60% battery per charge, but i dont think that even more safings would be possible
and with the app "tasker" you can even script this in endless environments

How does JuiceDefender save the battery? I have used many battery saver apps (including Juicedefender) and I always find that they run in the background and kill the apps which I would close anyway. Does it do anything besides kill background apps? By now I've deleted most background apps and have only kept the apps I want (which are few) and I still find battery life subpar.
Also definitely keeping 3G/4G off is a huge help. Wouldn't be able to make it very far without turning those off

I use Autorun Manager pro to freeze Google Play Services. Funnily enough, Play Store and Google Maps still work like a charm yet Google Play Services don't run background
Edited: With stock rom, install SetCPU and change the governor to hotplug. Underclock max frequency down to 800 MHz. You won't notice much different for normal tasks like watching videos, sms,...That setting is enough for me to play FF4 on MyBoy but playing heavy graphic games might not be snappy tho.

For me not using gaaps improve battery life. Every one knows for google play service that you cannot stop Instead I use calldav for my contacts.
