Hey all, I'm new here since I just bought a used G1 on Craigslist after losing my previous phone, so this is my first Android phone. I rooted it and I've been messing around with the phone for the past week.
Everything's been working pretty well, but my battery behaves strangely. I'm current running BiffmodV2.1 on 2.22.28.25 using ezterry's kernel. I just did a clean wipe and calibrated the battery too.
The problem is, when it's sleeping (I put the end button behavior to sleep) it uses barely any battery. I leave it in sleep mode overnight and it goes down by maybe 2% tops. However, the second I start using it, the battery starts draining like crazy. It uses maybe 1% for every 1-2 mins I'm using the phone. I turned everything off (wifi, gps, data (I disabled data because I don't have a data plan), background data, sync), turned screen to dimmest, and setCPU to 528mhz. Even with all this, it still drains severely. When I use it for music with the screen off, it uses about 1% battery every 10 minutes, much better than the drain is nowhere near what it is when the screen is on (minimal use without music). When I put it to sleep with Wifi enabled, it also barely drains any battery, but same thing happens when it's awake.
Does anyone know a possible solution to this? I also recently bought a 1400mAh battery, but it's most likely coming tomorrow. The current battery is pretty old, it's the stock battery that the previous owner has been using for the past 2 years, but even then, it doesn't explain the difference in the battery drain.
TL;DR G1 battery drains like a mother when awake, uses almost no battery when asleep even with music playing. Looking for a fix.
EDIT: I also tried Super D 1.11, Chromatic, Cyanogen, and a few others. All had the same exact issue.
I'm having this exact same issue, my phone also turns off randomly when I'm using it. I didn't have this issue when using radio 2.22.27.08.

Sounds like it's time for a new battery. It cant be the rom doing it since you've flashed so many and it still does the same thing. Try out your new battery when it come I'm pretty sure that'll fix it.
Got my new battery, and things are much better. It still drains a bit fast with the screen on and doing stuff (texting, browsing, etc) but the battery life is much better now. I'm guessing the new battery fixed it!

Hello, I've recieved my AT&T Tilt 8925 (Kais100) unit a week ago and ever since I've experienced awful battery performance. The item shipped new (not refurbished supposedly nor defective) and included a Samsung battery. I changed to Dutty's v3 ROM right away (flashing was successful, I also switched to radio version 1.27.12.27) and last night switched to Q-Mobile v1.2 to see if the ROM was the problem, but it persisted.
My battery drains extremely fast, even when the unit is off it drops 10% after 8 hours (overnight and also throughout the day, I'm leaving the unit at home while I solve this issue and it's always off). The unit does not have a SIM card inserted and the Phone function remains off, so does WiFi, Bluetooth, Beam, 3G, etc. It's also muted and has no alarms activated, nor background programs running (I'm currently running a freshly flashed Q-Mobile v1.2 ROM with a hard reset done as well).
I've read about battery perfomance extensively but haven't ever read about the battery discharging while the unit is off, and given the fact that I'm NOT using the phone functions, I barely believe this can be normal behaviour. I purchased 2 units from the same source and both are having similar issues with battery perfomance.
I'm currently testing a borrowed OEM Dynapack battery from a friend's Tilt to see if it shows the same behaviour as well to discard the possibility of a faulty unit. Note that I'm using the OEM 1A charger and leave the unit charging for several hours.
If the battery proves to be defective I'd have to get one (or contact the seller to see if he'd respond to the issue). Can someone recommend a cheap/reliable battery that could be bought online (eBay, etc.)?
Thank you very much! I hope that someone has a clue on this issue.
Best regards
Sebastian
Just to clarify, is the phone actually OFF, or is it in standby? If it's in standby, 10% after 8 hours wouldn't be unreasonable at all.
Uhm, it's on standby I guess (when I turn it on again it's instantaneous, not like when you soft reset the unit)...
I'm new to PDA phones, I had an IPAQ RX3715 before with WM2003SE and I could leave the unit off for days without battery drainage. However I may not be too familiarised with these new units' standby/off functioning. If in standby and with the Phone function off (meaning that the device has "nothing to do" other than being off) it's normal for the device to drain the battery so much I would be disappointed.
As a sidenote, my friend's Tilt is not draining while it's on standby being on the same conditions other than the fact that his unit has the Dynapack battery.
Regards!

I have the same rom and the same problem. I was at the hospital all day i made two calls and about mid day my bat was at 30%. I think its duttys rom V3 causing the problems. Changing roms now.
I could be wrong, but I think your phone is fine, these devices just consume a lot of power. 10% over 8 hours would be totally normal in my opinion. Is that the main reason that leads you to think there is a problem with your phone? Have you ever had a pocket PC before that had better battery life? When I got my first PDA I thought the same thing, but I realized that they are not like normal cell phones, where you could just recharge once every couple of days. PDA's must be charged at least every night. If you use GPS or wi-fi a lot you're probably going to be charging sometime throughout the day as well. I just got into the habit of plugging it in every time I get into the car, and when I get home I plug it into either the computer or the wall charger. There are after market batteries available, but if you want a drastic increase in amp-hours, the battery is going to be bigger and it will require a new battery cover. This is totally unacceptable in my opinion, as the device is relatively large to begin with. My advice would be to only activate a radio if you are using it, and de-activate it when you are done. Also just get into a routine where you are charging it whenever possible. Another thing, I just flashed Dutty's V4 RTM, and I must say the increase in battery life was very noticeable. Don't let me confuse you, though. From the information you supplied, I really am not able to tell if there is a problem or not, so give some more information and examples of battery life so we can figure out if somethings wrong, or if you just aren't used to the amount of consumption of this type of device. Hope I could help. Cheers!

Yeah that's not normal. You got any radios besides phone running throughout the day?
Thanks for your thorough reply. Picking on what you mentioned, it's true that I'm new to PDA Phones, as I mentioned I also own an iPAQ rx3715 with WM2003SE and my idea was to replace it. Judging the fact that PDA-only devices, to my eyes, are nowadays dying I thought I'd get me the latest and most complete device available WITH GPS, since I was using my iPAQ together with a GPS Bluetooth Receiver with much delight.
What I experienced with my previous device was that battery performance was never an issue, it did consume power as any PDA, but I didn't find myself worrying about it, it never dropped when off and it would last me several days.
Since I'm using my Tilt with the Phone function off I _thought_ it wouldn't need any power for anything... but it might be that these new devices, or the new WM6 architecture is different to that of WM2003SE/PDA only devices... I don't know, but it just sounds strange to me, although if it's normal I'll live with it- as you say, I'll have to be charging it 1-2 times a day.
On the one hand it would be good for me to know that my device is ok, but on the other hand it means that battery life isn't even close to what I expected... I had read people complaining about it but in general I tend not to be overly critic about the defects of devices... but it seems that it's the case. I meant not to use the phone features and thus I thought it wouldn't be consuming power on standby seeing that the phone should not be running anything on background...
Thank you again for your reply. If anybody else has a word on this I'd appreciate it.
Best regards
Just as an aside you will notice the battery life getting better after a couple weeks it seems the battery has to be conditioned so to speak. Also do you have any kind of push email on your phone as if you do that does use quite a bit of power, you might want to set it up as a pop3 account and set it to check emails every so often instead of getting them as soon as they come in.But I have amde it a habit to always use my charger whenever I am able to as these batteries seem to be happiest when topped off whenever possible.
Hello again, I'm still experiencing this problem and it seems not normal.
Simply put, I fully charge the device. I turn it off. It discharges by itself with all wireless functions off.
Today I did a hard suspend (keeping off pressed) with battery at 60%... when I turn the unit on 7 hours later the battery was at 6% with a critical warning sign.
I'm NOT using the device, I turn it on, use WiFI for 3-5 minutes then switch it off and put the device to suspend. I turn it on after a couple of hours, play with the menus and turn it off again. Just by doing that the battery drains by 10% every 5 hours or so, sometimes it won't even turn on due to battery drainage.
Is this NORMAL? I need to know if my unit or my battery is defective so I can return it to the seller in time...
Thanks, best regards
Sebastian
Battery life DOES seem to improve with time. The first day my battery wouldn't last for 5 hours! Keep charging your battery and letting it drain as much as you can (whether or not to let it fully drain is debatable), and I bet you'll see some guaranteed performance.
Also, what would help a lot is if you found and installed the Today plugin BatteryStatus and checked the "Show More indicators" option, and see what your battery drain was. The normal is between 150mA and 300mA when you're on the Today screen. Any more than that, and you most likely have a problem, assuming connections besides phone are off.
sounds normal to me, turning off you mean by pressing the button on the right side of unit? if so, mine is the same way
I'd say that was definitely not normal performance. On average, I use mine for at least an hour worth of talk time, an hour or two running TomTom, numerous SMSs, and at least a couple of hours reading books. I charge it every night, and the battery is generally running at around 50 to 60% by that time. I'm surprised at how quickly yours is draining.
I have an RX3715 inhabiting a drawer, and, while the battery life was a lot longer on that device, the battery was a lot larger, and the screen lower quality. The fact that it is not connected to a mobile network gives the battery a much longer life too. When I used it purely for TomTom, connecting to a bluetooth receiver, the battery faded very fast.
I've had a Kaiser since day one. I have found that adding a comm manager that allows forcing the phone to Edge give huge battery savings. In standby with the phone radio On and BT radio ON, WiFi OFF, my phone drops 4% over night very consistant. On Edge battery lasts days.
The only time I get fairly high battery consumption is streaming with 3G. Edge is so much more efficient on the battery, so if you don't need the speed, throttle down!
The only time I've ever found the phone Dead or close to dead after only a few hours on standby was when I had WiFi ON and the phone in standby. I can't pinpoint what exactly causes the condition, but when it occurs, the phone is HOT and the battery heavily drained in a short time. This has happened with both Hermes and Kaiser. I never leave WiFi ON when not needed, and have never seen severe battery drain since.
I do sometimes turn off all radios except WiFi, and then use wired ear buds and stream Slingbox video to the phone over my home WiFi LAN. I can get almost 4 hours of watching on a charge.
The battery should not be draining when powered off, but not much at all when put in sleep mode. Get yourself a replacement Testing.
As an aside, Alex's WM 6.1 BETA 2 has given me the best battery life of any rom. Only about 25% of the battery drains per day. With most other roms it's 50-100% per day.
Hello, thanks to everyone for your replies. It's strange because I've been doing lots of test, switching batteries (I have 4 units to test now) and I get inconsistent results... the 2 most problematic units were bought from the same eBay seller and got their ROMs changed the first day, the 3rd unit still has the AT&T ROM and was apparently not draining as fast. The problem is that the 2 first units seem to get battery drains overnight in flight mode of 10% and 2 times one of them got a 0% critical battery status just by being in standby and not in use (none of them are working as phones and have the function off)
The odd part is that for some reason this happens only sometimes, now I've switched to Sleuth's WM6.1 ROM and the problem is gone for now, I'm still at 90% since 2 nights ago having turned on GPS and WIFI for 5 minutes each 2-3 times... the other 2 units have been in standby from 100% charge and they haven't dropped either! And they're using the AT&T ROM and Q-Mobile v1.2 respectively... what kills me is that I cannot say what's wrong, cause I've swapped batteries, swapped chargers, swapped ROMs but cannot trace which is the problem (or if there's a problem at all)...
Perhaps it's normal for the unit to sometimes drain 10% after 8 hours of standby in flight mode and on other times remain at 90% for 2-3 days if not in use...
Thanks everyone for the read, I'd appreciate any comments
Regards
Sebastian
What radios are u using. Try changing radios
10% loss overnight in standby would be normal.
Does the unit get warm when you notice rapid drain?
I wonder about the "old" active sync problem - does the device show any running programs when you turn on?
In general you should expect to get a days worth of power using it for the odd call, perhaps an hour of wifi and perhaps an hour of prgram use. Of course all taht is very variable but I generally get away with a charge once a day. Occasionally, I take it from it's holder and it's warm to touch, but usually it's 'cos I've forgotten and left something like tomtom running.

Hello,
I recently got my nexus, and rooted only two days after receiving it. I installed cyanogen's latest. I am getting low battery; in only 5 or so minutes, the percentage goes down by at least 2 percent (while using). I looked to see what may have been draining the battery, and found that the display alone was using 62% to 75% of my battery. I tried undervolting, but the display seemed to still be in the same draining range...
Is this a hardware related problem, or is this a common nexus thing?

same here, really starting to piss me off when i see people talking about 70% battery at the end of the day while my phone dies in 6 hours
Cyan?
Woah, I think this might actually be cyan's Rom.
I flash enomther's rom and i got display percentage at around 15-16% ...
I think cyan will look into this soon enough...
But for now... I guess I'm gonna wipe... :/ and stick to enom's or some other ROM...

I think the problem is only with a few people, but I know others are experiencing this. This might be something with the "latest" nexi. But idk, it's a mutual issue, a fix should be coming
Probably you are right...
But, I would like to know, what settings peolple use: like updating wheater every hour, emails, widgets,..ham many apps are running and so on, ... perhaps connected to...sometimes people dont even know that
Edit: I got my Nex in january.
The change in the display usage percentage is just due to the way the powermanager works. Its not using more battery, its just displaying how much power it is using more accurately.
have the same problem.
100% airplane mode ON no WIFI, in 5 hours 72% battery remains . (PHONE IDLE took most of this - my G1 could go 1 month with this settings)
IN 12 hours in was 6% and with LOW use of my N1.
Yesterday I removed numbers in my battery and it was a litle better, not much but a little. (about 8% better)
I had 5.0.5.1, 2 and 3 and everyone had the same problem!
CM please take a look at this. What do you need any LOG info or something!
Have you tried wiping battery stats, then charging to 100% with it off, then booting into recovery and wiping battery stats again, then charging to 100%? The few times I've had battery issues that's taken care of it for me.
I flashed cyan again with a wipe (again), but got the same thing.
On enom's rom, I get beastly battery. I think we just have to wait for a fix for the people who are affected.

Do you need root to wipe battery stats? how do you do it?
Well I did the wipe battery about 3 times and in OS it was already green light 93% full.
I WIPED and put the power in on NON POWERED PHONE. It took 1 hour more to come to the green light . than I wiped again and went to boot up.
at 11PM i had 100% battery went into airplane mode wifi OFF.
And i did one other thing. Some of you had the battery drain issue with trackball wake. So I disable it.
7 hours of this and I got 97% - beautiful
before that I had 72% so there is a difference.
Now I have to see if the wakeup trackball is the cause of this or the wiping the battery stats.
Will eliminate one and other and keep you posted
I took my phone off the charger at 4:30am and the next day at 5:30 am i had 12% battery left. i used my phone a total of 3 times. most of the time it was on standby. i have setcpu with my phone UV and UC to try to save battery with profiles set up. in battery information 85% of the phones battery went to cell standby. Any suggestions on how to improve this?
Try wakeup trackball OFF in spare parts and battery % OFF in upper taskbar.
I have now from 100% to 59% in 7 hours. wifi ON all the time.
I have tried to wipe battery settings and charge fully with the phone off, but after the full procedure, I still get the same end result. I attached a picture of my battery usage.
Im pretty sure i saw a post online about the newer nexus's that were released having a better display. If this is true then wouldn't the phone's hardware alone be using more battery?
I can confirm I am having the same problem. I wasn't sure until I checked battery usage overnight. It used to be that with my phone on airplane mode I would use about 2% while I slept. Now, it's 9 or 10% with "Phone Idle" taking the lion's share of it.
I have tried deleting batterystats.bin after a full charge; powering off (while on charger); charging up to full again, but this has not solved the problem.
A few notes:
When the phone is idle (but not in airplane mode) it uses about 1.5% per hour (compared to about 1.1% in airplane mode)
I am using setcpu profiles to keep cpu usage right down when idle
Around the same time I upgraded to 5.0.5.3 I also started using the himem version of fastboot. And yes, if you suspect I don't know what I'm talking about here, you are quite right
For my next trick, I will try resetting battery statistics via recovery. What fun!
I've kept the cyan rom, and changed some settings to increase battery life. I turned off the battery percentage icon, and turned off the trackball to wake. I still got that the display was using a lot, but the battery still lasted pretty good. I guess there isn't too big of a problem on my side. It probably is the "newer displays" on the "newer" nexi. Maybe there really isnt a big problem
I changed now from CM to Enomther's TheOfficial Nexus1 1.8.1 and battery now works great.
I unplugged the charger at 12.00 am at midnight and with quite good use, not extremely havey but a good use I had 30% battery left at 20:00 (08:00PM) that day.
I lost only 2% from midnight to 7:00AM in my airplane mode and with Gmail check 10 min of phone calls wifi ON all the time checking web pages and showing off my live wallpapper at my work I had at noon (12.00PM) 70% battery left!
I LIKE IT!
now I'm thinking to push Kernel - .32 & .33 to see if there is any change with my battery
http://forum.xda-developers.com/showthread.php?t=653598
After resetting battery stats in recovery, I still lost about 10% overnight while on airplane mode.
For my next trick, I'll use a task killer like "Process Manager"* to keep everything unnecessary switched off overnight. Maybe I'll be able to narrow it down to an application if it's not something integral to the actual ROM.
*Yes, I know it will use up the battery too
Hey everyone,
I'm not sure if I have an issue with a defective Captivate or if it running as intended. That's why I've come to you guys for some insight.
Here's my scenario:
A few days ago, I decided to leave my Captivate off of the charger overnight to see how much battery I would awaken with. It was just a little experiment I thought of to see how much the battery drains while not having anything intensive to do (such as power a screen). I fully charged the Captivate to 100% before setting it on my desk and going to bed. As normally, everything was turned off except wi-fi. When I awoken the next day (8 hours of sleeping), to my surprise, my battery was down to 27%. I was shocked that something could have drained almost 70% of my battery overnight. I downloaded an app called Spare Parts as a recommendation by some people and I seen "Running 100%" which means that the phone spent no time sleeping. When I look at any partial wakelocks, it showed "Android System" as a full bar. I assume that it could be a bad app that was keeping my phone from sleeping.
I restarted the phone, battery pulled, charged up and uninstalled some apps. Everything seemed back to normal as when I checked the the running %, it was proportionate to how often I was using the phone (not at 100%). I specifically checked if the phone was sleeping and it was through some monitoring. I would use the phone for 1 minute and then let it sleep for 2 minutes and you could see that the running % went down, as it is suppose to.
I kept monitoring the running % over the course of the day and it was fine. The less I used it, the lower the % would go; the more I used it, the higher. I also monitored what kind of apps I was firing up and I specifically made it an effort to not open any apps that were out of the ordinary. If I did, I checked to see if it kept my phone from sleeping and it did not (through my same usage tests as above). However, even after my close monitoring, sometime during that day, my phone would stop sleeping once again. I could tell because my running % never lowered, no matter how long I didn't use my phone. It would keep climbing which means it no longer slept. I made sure that I didn't do anything out of the ordinary too as I used the same apps as I did when the phone was sleeping fine. I checked "Android System" and it was getting larger. The battery was around 80%.
I charged up the phone again to max and made sure that nothing was preventing my phone from sleeping. Did the tests again and running % was proportionate again and I double and tripled checked to make sure the phone slept. I then left the phone not charging again to see what would happen as I would have no interactions with the phone to open any apps or change any settings. To my surprise, my battery was down to 60% (~ 6 hours of sleeping) when I awoke. I checked the running % immediately in the morning and it was at a very high percentage. "Android System", once again, dominated the partial wakelock portion.
So what's going on here? It doesn't actually seem like I'm doing anything on the user end to prevent the phone from sleeping. How come it decides to act up all of a sudden? If it was a bad app, how come it decides to prevent sleeping all of a sudden and not before? Even if it was a bad app, I didn't even launch anything while sleeping. Does the phone decide all of a sudden to stop sleeping?
The apps I use are:
Tasker
Y5 Battery Saver
Launcher Pro Plus
Twitter
SwiftKey
NHL Gamecenter
Handcent SMS
doubleTwist
Dropbox
Does anyone have the same problem?
Any help is appreciated.
Get rid of any task killers and battery savers they do more harm then good and most developers recommend not using them, they cause battery drain. The only battery app I use is Juicedefender because it keeps the phone from connecting constantly and keeps apps from running in the backround. I set it to connect every 15 min for 1 minute to sync, I turned off all notifications because they annoy me and I don't need to be notified everytime I get an e-mail or someone posts on Twitter or FB. My battery life has improved greatly once I dumped task killer. Also, I am running a Froyo mod and my battery is amazing now and my GPS works.
If you are in an area with a weak signal this will kill your battery because your phone is constantly searching for a signal and trying to connect. Also turn off wifi if you are not near wifi this will save battery.
Also try calibrating your battery and bump charge it. Here is a link for that. http://forum.xda-developers.com/showthread.php?t=765656
The battery will improve, mine got better after a few weeks of break in. I am at 60% been unplugged since 10 am and I made plenty of calls, checked e-mails, sent e-mails, checked XDA developement all day and I have plenty of juice.
Good infos. O agree with not using task killer

Hmm, thanks for the tips but there still seems to be something lingering around in my system that doesn't allow the phone to sleep. It seems to activate all of a sudden as well without user intervention.
I again left it overnight and it drained again when I woke up. I lose significant battery overnight when I sleep. I'm thinking about just restoring to factory settings. I've only had the phone for a week so I wouldn't lose that much data. I'll monitor it from the onset once I factory reset it and see if it's a hardware defect or something that was bad in my phone.
Do you have a live wallpaper installed? Also, do you have a bunch of Widgets on your homescreen? Are you constantly synching with e mail, FB, etc? No doubt something is running all night. It's not the phone, it's something you have installed. I set mine to sleep with Juice defender at night so nothing syncs. Check your wireless bill to see how much data is being sent while you sleep. Why not charge your phone while you sleep?
Sent from my GT-I9000 using XDA App
Nope, no live wallpapers and the only widgets I have on my home screen are the LauncherPro Plus widgets, Smooth Calendar and BattStatt. The only syncing I have going on is Google Calendar and Gmail but both of those shouldn't cause the phone to not sleep.
I was thinking of using Juice Defender but I would rather just get to the root of whatever app is preventing my phone from sleeping and kill it at the root instead of finding workarounds. For all I know, my phone may not be sleeping not just overnight, but with normal use as well and it would adversely affect battery life throughout daily use. I need the piece of mind that my phone is properly sleeping.
And I have no issues with charging while I sleep, but again, I need to find the root cause. If for whatever reason I'm can't access a charger overnight in the future (such as if I sleep over at my gf's house), I want to know that I won't wake up with a dead battery in the morning.
I really appreciate the help though.
As for what I decided to do next, I actually factory restored my phone yesterday morning and so far it is working well. I did not download any apps at all to make sure that this problem didn't persist with a stock phone. If it did, I would know that it's a phone defect and not something I did. Throughout the next week, I'll be installing different apps one by one to see any one of those apps will cause my phone to not sleep. This will allow me to isolate the app. It's long and tedious, but I would go through it for better battery life. So far, it's been working as I'm already through 10 hours on my phone with moderate use and it's only at 50%. Whatever was destroying my battery before absolutely had an effect on my daily battery life as I would struggle to even get 10 hours on my phone with moderate use.

I find your post very interesting. I have not yet used Juice defender, however, I am now more keen to battery drainage. I talked on the phone for about an hour the other day and my battery went from 100% to 40%. I find this unacceptable for a phone. Imagine taking conf. calls and conducting business in the field throughout the day. My battery would be dead in two hours without checking email
I hope you can reveal your findings to help us all.

Battery problem fixed using the simple technique similar to the one shared back in this thread.
I used to lose 10% per hour (or there abouts) and by 5 or 6pm needed to go on charger. At the very best with no use it dropped 3-5% in an hour.
Now its all changed...
After being off the charger for 35 min and taken 2 calls and sent a couple of txts she still read 100%.
At 5hrs 17min off the charger it is at 81% and there has been 6 calls in total and about 9 txts, plus a couple of appointments added.
Here is what they said to do and it worked...
1. Charge the phone for 8 hours, but make sure it is turned on while charging.
2. Unplug the phone, turn it off, plug it back in for 1 hour.
3. Unplug it, turn it back on for 2 minutes, then plug it back in for 1 hr.
Then unplug and enjoy the new battery life
Sounds too easy to work, but bugger me, it did!
27% is clearly abnormal.
Sometimes, I put the phone on it's charger after a pull day only using 27%.
I read somewhere on XDA that some early phones had defective screens that would only shut the backlight off and not turn off completely. Don't remember what came of that thread though.
I have a battery drain issue as well. My Captivate is 2 days old and been charging it every night. The first charge was done via the computer while transferring music over. After moderate usage (1 hour of music, browsing apps, learning how to use the phone, etc.), the battery died after 10 hours. GPS, and bluetooth was turned off. WiFi was used for maybe 20 minutes. When I got home, I charged it overnight for around 10 hours.
Today, the phone died on me after 9 hours. I rooted via z4root and applied RyanZa's latest OneClickLagFix, which both apps can be found on the market. Before that time, the battery said there was about 80% remaining. Fast forward to 6 hours later and the battery is gone. Again, moderate usage.
According to *#*#4636#*#*, my Screen On is at around 60%. A few other bars are pretty high as well, but I'm not sure how to do a screenshot on the Captivate right now. The only method I found requires using a PC. Plus, my battery is dead meaning I have to charge it overnight again.
I had an issue for the last couple of days, just figured it out earlier today. I had a corrupt thumbnail file on the external SD so my android.process.media (something like that) was constantly running.
I first realized something was wrong before I determined the battery life was bad when I noticed that my CPU was constantly at 11470-1200mhz or 975-1000 when I disabled the OC.
Unmounting the card would allow the CPU to drop to under 200 at idle so I knew it had something to do with the external SD. Turned out there was a bad file under a DCIM (camera folder), so after I deleted it, it became smooth as silk!
Of course it's still an i9000 rom so battery life is still questionable

Sorry for the hijack!
Here are yesterday's results:
Does these results look normal to you? I'm particularly concerned about the Social Hub and screen, and running. They're all higher than I expected. The brightness of the screen is set pretty low, maybe 2/10 of the brightness bar. As for Social Hub, well all I got is the Facebook widget, which is set to sync every 4 hours. Other kinds of syncing is off. GPS is off too. I don't have any battery saving type of apps yet, except for RyanZa's OCLF which includes the WiFi timeout.
I ended up charging the phone at 5% battery left. I had to sleep!
After a difficult update with Kies I was able to upgrade to Gingerbread.
Everything seemed to go well the first time then I found drain battery and slowing down on the system.
So I decided to make a simple wipe which reported the phone as fast as at first, but the battery still has problems.
In one night from 90% it was completely drained so today I decided to use 'Battery Calibration' made from user 'marosige'. This time in 5 hours I lost 30% of battery life using some sms, internet for 15 minutes, and playing cut the rope for 10 minutes. More or less.
However I have to see if the battery loses all of a sudden like last night which is the biggest problem.
All of this is not normal have you any advice?
Thanks in advance
Hi Fattox,
Dont worry your socks off I flash Roms quite often and this requires me to calibrate the battery. Sometimes with certain Roms I find the battery may drain quickly the first time and then things get better.
You say you have calibrated so that means the app you used should have deleted the old battery stats from your systems file. In saying that if you follow these next few step you should be ok (unless there are other issues causing the drain)
1. Make your you drain the battery fully until phone dies and can't be turned on by pressing the power button then....
2. Plug in phone and keep it off until battery is fully charged. Don't take it off charge as soon as it says full. Just let it go for about an hour more or so to ensure it's at capacity.
3. Turn phone on and use as normal until dead...
Providing there are no other issues causing the battery drain you should find your battery usage to be satisfactory. Remember to turn off wifi and gps when your not using them as well as maybe turning your screen brightness down. Anything that uses less power the better....
Hope this helps.
between the recalibration with the app and your point 1, I had the same problem: during the night the battery loose all the energy.. so strange.
All this after I upgraded to Gingerbread.
I'm going to test all this week then I'll spend my warranty.
Is anyone else having bad battery life after the update? Cell Standby and Phone Idle used to draw most of the power before the update, now they're low on the list however Android OS is eating all the juice now. Android OS gets up to almost 70% usage overnight and the battery drains a good 30% or more just sitting idle for 6 hours.
I installed a program called watch dog and it's telling me that "Base System" seems to be the culprit with lots of CPU use, particularly when the phone is idle. I've tried a variety of things like uninstalling recent apps I downloaded, disabling the 4G and 3G radios, trying airplane mode, changing settings, etc. and nothing has made a difference. Really want to avoid trying resetting to factory default.
Have you tried recalibrating the battery or tried bump charging?

Since I use my nav dock in my truck to stream Pandora over my stereo, it gets charged several times a day; however, Android OS is now my big drain as well, where it used to be idle or screen using the most. Since unplugging exactly two hours ago, it has drained down to 70% on the stock battery. (I only use my extended battery when I will be away from a charger for a long time. Makes the phone too thick for my pocket to be comfortable.)
On a seperate note, Google Voice now hangs my screen as well when listening to voicemail. Hey, at least I don't get the random reboots and power ups... :what:

I doubt calibrating will fix the issue because I don't think that's the problem. A system process appears to be hanging and causing the CPU to run constantly. Maybe a bad update install?
Either way I used to get much better battery life before the update. Never had any of the random reboots or many issues with data like others.
My battery life seems somewhat worse after the update. Everything else seems somewhat improved.
My battery seems about the same if not slightly better after the update.
I do a few things to conserve battery which really conserve the battery.
1. 4G off unless I need it.
2. Battery mode set to 'maximum battery saver'.
3. WiFi sleep policy: When screen turns off (although I think the maximum battery saver will turn it off automatically)
4. Display brightness: 0% unless I need it.
