Before anyone accuse me of it, I did, in fact, look through the other battery threads on this forum (and other forums, for that matter), and I've already applied numerous tricks. I managed to get my phone to last roughly 9 hours from my typical usage, which now makes it comparable to other phones I've used in the past.
However, in about a day or two, I'm going to be getting a bluetooth headset...which basically means that I'm going to need to keep the Captivate's bluetooth on 24/7 (or, at least, most of the day). I really don't know how much battery this is going to cost me on the Captivate, so I'm trying my best to make things better now to make things smooth in the future. However, I appear to be at the end of my rope.
I have pretty much gimped the Captivate as much as one could reasonably take (more, I'd dare argue). I cut all of my volume down to half of what it was and I removed most of the quick icons. I also set a completely black wallpaper, I turned off all animation, and I turned the brightness down to its lowest setting.
I honestly don't know how to make it any worse. The SAMOLED screen is basically a meaningless PR term to me now and I'm actually missing phone calls from sheer lacking of hearing my phone ring...despite it being right in my pocket.
Going even further, I also attempted to switch to ADW.Launcher based upon recommendations by others that it increases battery life (I found that it had little to no effect). I also attempted to severely underclock my CPU (down to 200Mhz) based, again, upon other claims that it increases their battery life all the way to as high as 30+ hours on a single full charge.
Somehow, underclocking my CPU actually made the battery die out faster.
Furthermore, I attempted to use programs (SMODA, 2G/3G) which claim they allow me to switch to EDGE because, for some God-forsaken reason, Android doesn’t seem to have any toggle for doing it. Unfortunately, none of them seem to work; rather than switching to 2G, they all just completely disabled data, which, unfortunately, is completely unacceptable to me. So at this point, I only seem to have a few more extreme (from my perspective) options. Once I actually get the bluetooth, I plan to turn off most of the auto-updating apps (email, weather, twitter, etc), and just update them myself periodically. Furthermore, I plan to turn off the GPS location feature once I get my GPS unit.
Beyond the above, though, as I said, I'm at the end of my rope. Once I employ the other tricks, I figure I might be able to stretch battery life to 9.5-10 hours, but I would like to go even further. If anyone could offer me some help, I would highly appreciate it.
if your gonna have a bluetooth headset on disable your ringtone completly that would be meaning less. if your near wi-fi a lot have it connect only though that.
also you can clock the cpu down to 100Mhz along with the GPU.
AND to force 2G/edge read my howto in general
oh the ext2 lagfix can also save you some battery life

I'm already doing the first sans disabling ringtone. I'm not so sure doing such a thing would be acceptable to me.
As for the underlocking suggestion, as I said, I underclocked the CPU all the way down to 200Mhz and the battery actually drained even faster. I doubt underclocking even further is going to help. Furthermore, I actually did try 100Mhz originally, but the performance was so horrendous that it was unbearable.
As for the lag fix, I already have it. Lastly, I knew about that 4636 technique to switch to 2G already, but, unfortunately, it doesn't appear to work for me. The setting doesn't save and 3G still remains.
EDIT: I actually found a way to make the above work. Simply dial *#*#197328640#*#*, then go Debug Screen > Phone Control > UE State Control > Change RAT to GSM. This will actually force your phone to use GSM only. This seems like the answer to all of my battery problems....except it doesn't work. Once you make the change, the INFO menu reports that it has been changed to 'GSM Only', but data appears to have been disabled. Restarting your phone makes data works again, but the INFO menu reported that data has been reset back to 'GSM/CDMA auto'. Yay.
If you haven't already, turn off GPS when you aren't using it. Use the Power Control widget to help. Make sure all of the things in the power control widget are off unless you are using it. And use advanced task killer if you haven't already.
i say screw underclocking let run at whatever i dont think it makes a difference.
forget advanced task killer, i like auto killer.
leave gps off unless needed, and backround data
switch to 2g when you can.
no live walls of course use dark or black, no updating widgets
i dumped stuff like juice defender, cause with backround data off i dont think it does anything.
flight mode it at night (when sleeping) if not charging
ive been running jh3 (now jh7) with sre. get to work (i run 2g at work)at 9am listen to pandora all day through bluetooth (which is on for 6-8hrs) and wifi (6-8hrs) good amount off browsing bout 30 min of voice calls, some texts email checking, more browsing, some games. on average lately after being unplugged for 13-17 hrs at the end of the day with 20-30% life left,using bout 3hrs of display, 30 min voice calls, bluetooth doesnt use crap bout 3%, media server usually 15%, cell satndby i wanna say 10%, im pretty happy i guess, even though im always lookin for better results, tryin the new sre with undervolting, heard some good things.
still when that seidio 3200 mah battery comes out im gettin it, dont care how fat it makes the phone, things to dang thin as it is, and without some sort of cover its like a wet bar of soap!!
What is your typical daily usage? I have fairly light usage (few games here and there a little music and a good amount of web surfing, app browsing and texting with a few phone calls using speaker phone) and I'm at 28 hours of use with 55% battery.
I have just the typical power saving tricks(gps off, bluetooth off, screen at minimum or 30% and my data doesn't sync automatically), no under clocking or anything. I should point out I'm running a euro galaxy rom and am not ever on a wifi connection.

Wow you are lucky. Yesterday I got 2 phone calls for a total of 3 minutes. I sent 7 text messages. I surfed the web maybe for 15 minutes. No games. Nothing else major. GPS off. Bluetooth off. Wifi on. Screen at 22%. Only background data I have is email which checks once every hour and a weather widget that refreshes every 6 hours. I got barely 12 hours in before my battery died.

Typical usage for me runs along this line: A lot of web browsing, perhaps 30-45 minutes of music, and plenty of IM. I also use Aldiko to read now and then. Calls do factor into this, but typically only two or three 10-15 minute phone calls.
Truthfully, I simply don't see how it is possible for you to use the phone for 28 hours straight and still have 55% battery. I could lose 30% battery just by leaving my Captivate on stand-by for 30 hours.
I certainly understand the interest in having the best battery life possible.
Are you in a work environment where you cannot plug it to a computer for part of the day?
Fortunately, I am. And I always have it plugged in in the car.
I don't want to have a powerful phone with all the features turned off in order to keep it going.
I dont see how you can get 28hrs @ 55% either, with the kind of usage he was claiming, i wouldnt exactly call that light usage

Well, I do have a work environment where I can keep my Captivate plugged in, but only half of the time. Other times, I need to move. Aside from that, it kind of annoys me to use a phone attached to a wall socket. I prefer to keep my smartphones plugged in only long enough for them to fully charge (or at least charge to 80+%), then unplug them for usage. This is kind of tough for the Captivate considering it takes 3-4 hours to fully charge.
I also fully agree with you on the last point, which is what makes all of this so frustrating.
*Sigh* It's really too bad the Captivate is my first Android phone; it's been kind of a negative experience for me so far. Ironically enough, the one issue that hasn't been a problem for me is the one issue most seem to be having -- GPS performance.

I am in class for most of the day so the phone is idle most of the time but i only play about 10 minutes of music with about an hour or 2 combined web surfing and games but my phone is still chugging at 39 percent battery life at 38 hours of usage. I guess that qualifies as light usage then.
edit: jm6 with unhelpful kernel and sre
also, you have let the battery die out completely and recharge completely with the phone powered off correct?

I'm honestly shocked at your usage. Am I reading right that in the 38 hours since you last charged it, you only used it for 10 minutes of music and a combined 1-2 hours of web surfing/games? I wouldn't call that light usage. I would call that hardly any usage.
Under such conditions, I can see why your battery life lasts so long.
I don't see why you can't get a days worth of usage out of your phone. Cell phone calls use the most battery - that is why the phone is rated at about 5 hours of talk time. This would be in the best signal area. If you are in a lower signal environment (especially in a heavy building all day) you will see faster battery drain.
I am not sure why you are bothering with BT if you are only talking on 2 or 3 calls - but if you take 3 15 minute calls that is at least 15% of your battery - the only way to change this is force the phone to Edge.
I would not lower ringtone volume - that is not a big battery saver in the grand scheme of things and you are missing calls - not a good trade off. If you are doing a lot of web surfing, go WiFi instead and you will see big battery imrovements. 3G voice and data suck battery - it doesn't matter if you have android or iPhone.
If you put your phone in Airplane mode you can go for 5 days between charges with minimum use.
The radio does kill the battery, I don't think the battery usage screen really depicts this. Since I've gotten my captivate my old BB Bold (at the time would only last 3 hours due to its degraded battery) lasts days on end with its radio disabled while sitting in my desk. I'd love to see native 3G toggle or at least a captivate catered app, I'd even pay for the latter

Well, that rating is probably the battery life if your decide to talk on your phone for five hours straight. I really, really doubt it takes into consideration the in-between times (games, apps, and, of course, web surfing). Phone calls undoubtedly takes the most amount of battery, but Internet usage is probably second place and, as said, I use that fairly often.
Lastly, I'm not planning to use my bluetooth exclusively for phone calls. I'm going to use it for calls, listen to music on the Captivate, chat on my PC, and so on. It's multi-usage.
Next, you're missing a lot of the things I said. As I said, I already tried numerous methods to force the phone into 2G; not one of them works (they either don't work at all or actually completely disable my data). I'm already using wifi as opposed to 3G as much as possible.
Lastly, I'm sorry, but using airplane mode to save battery is not acceptable. If I'm even willing to consider this, then I might as well just turn off the Captivate to save battery.
I just read something about an external sd card being another battery drain.
Took mine out and we will see. I was already getting through the day with about 20%left.

I didn't meant to suggest that airplane mode was an alternative, just to point out that the cell radio for Voice and Data is your biggest drain.
If you are going to use the phone for almost an hour of talk time, heavy web surfing and BT connections for tethering then your battery life will be limited. If you are using BT to chat on your pc - then maybe tethering with USB would be better - you could charge at the same time.
Your other option is to get a spare battery.
And I did read what you had to say, I just didn't realize how much you were expecting your phone to do. The only numbers your provider were around talk time.
I use my phone a lot and I charge it every 24 hours - I am more then satisfied - but I know that if a spend an hour or more talking on it and bunch of web surfing that I will have to think about charging it as my usage increases.
There is a way to force the phone into 2G. It isn't very user friendly. I have tested this and it works great.
Enter the Phone app.
Dial *#*#197328640#*#*
Select [1] DEBUG SCREEN
Select [8] PHONE CONTROL
Select [4] UE STATE CONTROL
If you want 2G, select:
[3] CHANGE RAT TO GSM

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
Hooray yet another Battery thread!!
Feel free to shoot me down or close the thread and ban me if people find this not useful but I though I'd share..
I'm running AOKP PUB with Matrix 8.5 on my N4 and battery on WIFI was great but once I switched to H+/3G I would see an increase in wakelocks and hence battery drain. I'm sure more than a few people can relate to this problem..
after 9 hours from unplugging my phone, going to and from work and arriving back home I would have about 75-70% battery left with light use. Now after installing Auto3G from the play store I am going home with between 88-85% left which is making a massive difference to how long my device lasts,
Typically I'm getting 2 days standby and between 4-4.5 hours data/WIFI and at the weekends 5-5.5 hours on just WIFI.
The app simply turns data off when the screen is off then on again when you wake your phone up and it will turn data on every 30 minutes for 1 minute so your apps and accounts can sync. I have try apps like this before on other phones but this one has impressed me, plus its free! I haven't felt like I'm missing out on fresh content from my widgets or accounts because the syncing seems to actually work. You can set delays on when the data switches off too!
Anyways, here's the link..

Best thing I have done to draw out my battery life is to disable location services and then reboot. This alone has given me an extra hour of screen on time. I used to struggle to get to 3 hours and now I am getting over 4.

Are you doing it just to get max longevity or are you guys really struggling to make it through a day? Mine has been excellent, best battery life of a smartphone I have had since my old Windows Mobile days.
best and most visible boost for battery life is turning off the localisation and dimming the screen
I wasn't losing any sleep over battery life, my N4 has always lasted at least a day but I was a little disappointed with how long a charge was lasting me on H+/3G compared to WIFI. Now I have no complaints on either..
"When the user unlocks the phone, data will be enabled.
When user locks the phone, data will be disabled."
Sounds a lot like Juicedefender that's been around for a long time. I'm sure its good for some people, but kind of defeats the point of having a smartphone. Especially for me when most of my messaging is through Whatsapp / Facebook.
I used to use juice defender and I found that it became too complicated for its own good. You can change the syncing interval but I agree if you do you messaging through FB or WA then its probably not for you. I dont really use either often so the 30 minute cycle works well for me and maybe others..
Its not really defeating having a smartphone since its saving you battery when your not using you phone, its stupid to have the thing draining away when it's just in your pocket..
i'm using this app on my N4 too and have to confirm that works like a clock, simple and light but powerfull as let you choose when turn data on and for how many minutes, how much to wait before turn data off after shut down the screen and when to turn it on after the screen goes on...
if you want to make the battery to last longer it's a very good app...btw i think N4 has a decent battery that can drive you till the end of the day without problems
I just have a Tasker profile to run my data sync once every 2 hours or if I open up Gmail or anything else that needs to sync. This cuts down on the constant notifications when my phone is idle. I haven't noticed a big difference with leaving my phone on auto brightness of if I just turn down brightness manually.

Right now my S6 has better standby on 4G and more life in use than my tablet has with no use!
Any ideas?
Can't speak for Lollipop, since staying with 4.4.2 and disabled auto updates. I only lose 2% in ten hours and the best Android tablet I have owned- especially in regards to low sleep bleed.
clearly something is not right have you factory reset it? That would be the first thing to make sure no apps are doing anything weird.
I flashed a whole new OS... should i wipe it?
You need to install a wake-lock checker, it will show how much time your tablet is actually in deep sleep mode, which uses the least amount of power, mine shows 97% time in deep sleep.
Some application can keep you tablet from going to sleep, alarm clock and sync can also, and apps/software you downloaded.
Do you get still get major battery drain after a reset, dont install any software/apps and the charge to 100% and then leve it for a few hours and then check how much power you have lost.

Over an 8 hour period (avg) with wifi on, my screen brightness set to 10-20 range (that is the brightness I prefer on my tab s), and with greenify I lose maybe 1-2% battery. You definitely have some program or service constantly running or waking up your tablet, and due to the interactive governor that samsung uses your tablet wakes up at 1.9GHz each time to be more responsive/save battery by handling what ever is needed as fast as possible so it can sleep again. Unfortunatly if some app keeps going "hey, hey, I am here, I need you tablet, hey, hey, ect........." that battery saving governor will murder your battery.
So i wiped and its still 48 hour batter!

Losing around 30% battery over night idle.

Do you need to have your wifi and sync on for business or something, if not turn them off, of use an app to to mange them like the free juice defender ect.
Just install it, make sure it is enabled and then make sure the icon is on your taskbar so it has not been killed, and them forget about it for a week and see how it goes.

for some reason on this tablet, wifi murders battery in standby. if you turn it off it lasts much better... but this tablet and this tablet only, leaving wifi on kills it horribly. but problem is, when you wake it for teh first time in hours and wifi activates, all of a sudden everything syncs and it's so damn laggy those first few minutes of use. it sucks. only this tablet. never had this issue with my nexus 7. that thing gave me 7 days stand-by time.

Try putting your tablet in airplane more overnight and see how much power it consumes. I lose 3% over 8 hours when I put it on airplane mode and disable wifi.
Im sorry but this is BS.
Its clearly faulty. its going to samsung. i demand a refund.
How much power wifi uses depends on the distance to the router and how much interference it has to try and break though to get a good connection which means using more power, that is why wifi uses more battery power on some peoples tablets than others do.

disregard.. just realized my screen shots were messed up. I'll post my standby time tomorrow.
Here is a very simple stock no root mini guide to getting 1-5% loss over an 8-10 hour period while sleeping or at least while the tablet is asleep.
1. Install greenify even if you are not rooted and even if you do that have the donor package there are many many apps that do not like to sleep, greenify will fix that for you.
2. Unless you are a Doctor, CEO, or someone whose very life hangs on getting the latest cute cat post while you are asleep try to adjust your sync times from under an hour to as high as you can. (If you are turning off wifi then it might still matter if the app wakes up your device just to see it can't sync)
3. Samsung has given you a very nice QHD screen. It is high resolution, Amoled, and other nice rhings but while you sleep you can not see it so turn the brightness down before you touch the power button to 5-15. If you wake up in a dark room and need to use your tablet that level of brightness is far kinder to your eyes and even kinder to your battery.
Just doing this generally kept my battery usage down to only 2-4% per night, of course then I rooted my tablet and installed TW detox 3.0 and now it is closer to 1-2% per night. Try any or all of these and I hope it works out.

losing 48% per day... screen brightness wont help will it when screen is off all day
Screen brightness is for those times that an app wakes up the tablet and turns on the screen to tell you something (new email, facebook wall post, new cat video, ect....) and yes it helps.
If you are losing 48% a day then you have some app doing something that is keeping your tablet awake for a good portion of the day. Or you have a defective battery/tablet. I can surf the web for a good portion of the day and maybe lose 48%.

Are you rooted. It's sounds like you have some wakelocks? If rooted you should use greenify and a wakelock alarm to fix the problem.
i'm curious to see what apps and how many you have installed. Can you post screen shots of your app drawer?

what email apps and cat video watching apps are you using that turn the screen on? no app that I have EVER turns my screen on at all. the only app that does that is on my phone, and it's from textra, an sms app that isn't on my tablet.

Granted, I'm only on day 4.. but still..
I've tried disabling LTE, simple watch-face, etc.. but can't get it to live for more then 12 hours without needing a recharge..
Do those of you reaching more then 12 hours use an always on screen? Gestures?
I did do a test overnight and it only dropped 20% (7 hours) - but my typical drop rate is much higher then that with casual use..
-mark
ps - I'm on-track for 12 hours again today, and that's with only having received ~3-4 email notifications which I just quickly dismissed in the past two hours so far..
For those that might be interested in this subject, I also posted it on reddit which seems to be getting much more traffic..

I just put mine on charge after 48 hrs with 3% left that is with screen always on off and only turning WiFi on when needed.I'm using mine tethered to my g6 without lte.
Firstly in my case I don't use LTE.
I've found having WiFi and gps switch on has made very little difference to battery life, as it's tethered anyway for this information.
I think the battery life has got better after a couple of weeks usage, and typically a full day has plenty left, nearly 50% on occasions.
Yesterday was a long day, and it managed 20 hours straight through
I usually get around 24 hours. But barely 24 hours (if I do anything except let my watch run idle on my wrist whole day, I don't hit the mark).
Screen always ON
NO SIM (doesn't even work in europe)
Always tethered to the phone
Tilt OFF
Gestures OFF
Location MIXED (decided to experiment a bit, seen no discernible difference in battery drain whether it was ON or OFF)
Watchface: Portions with 4 complications
First couple of hours is sleep tracking with screen turned off (but constant HRM sensor activity), which consumes slightly less than regular operation.
Today I turned always screen off and holy **** what a difference. After 12 hours I'm still at 80%. So the clear culprit of this is the screen. I think I will try to get used to this, it was wasting energy 99% of the time before anyway (I'm not looking it at it all the time).
I end up getting through the day at about 30 to 50% with everything on except for LTE which I toggle on and off during the rare occasions I need it. I usually use brightness 6 during the evening and 8 during the day, I find the auto-brightness too dim on every occasion. On the other hand I've had a few random days where it rapidly used it's battery and I was down to power saving in the afternoon. Havne't figured out what is happening when it occurs but when it happens my phone also rapidly drains. Other than that I wish I could increase the screen on time, it sometimes dims before I've done what I want to do and I feel like I have enough spare bat to burn a little more keeping it on longer.
My Answer, you don't. I leave everything on and charge it, like 3 times a day. I'm lucky because I have two others to swap to during charge, but I even bought a second charger for work when I do not have those available.
I simply do not want to reduce any features of the watch, so I charge it often. That's just what it is if you ask me, you're not going to miraculously get this thing working for 2 days, simple as that. So use it big, and charge it often!

Is there a faster way to toggle cellular on and off other than going into settings?

Not that I know of and for me it's a double downer, when I use the watch standalone I don't need bluetooth. I menu dive to switch both and then revert when I'm done. The radios should be available from the pull down quick settings IMO, it would be enough to have an icon there to open them all and you could toggle those you need from there. Considering the wasted space on that pull down it becomes a bit of a what were they thinking issue...
Hi guys i'm interested about lg watch sport here in europe and i'm willing to buy from ebay korean model. My cuestion is can i use it completly without pairing to phone with sim inside. Can i set it up without cell phone? How about using facebook, viber ( making VOIP calls) email etc... thanks

You need to pair with phone initially. It also makes it easier to copy your accounts over to the watch. After you set it up, you don't need your phone anymore BUT if you keep it on cellular the watch isn't going to last.

From my time with the watch it appears that having cellular on has little impact on battery life as long as you're within range of your phone. The part that does affect battery life with cellular on is IF you're in an area with just complete sucky cell signal to start off with. (IE my workplace) that will kill battery.
I had battery draining issues at work even with cellular off at work but I figured out that although on my phone when connected to work wifi I can get to the play store on my phone but on my watch it can't get to the playstore or communicate with google. My assumption is the watch is draining because the google play services can't connect/sync with google therefore causing it to stay awake and drain. Watch battery life has been much better when I disable wifi on my phone BUT now my phone drains a little faster because it's not on wifi.
Bluetooth Autoconnect app has been a lifesaver when having watch/phone/BT headset/BT car connected. You can set up profiles and priorities so that the car/headset/headphones take over the call duties so you can hear phone calls through those devices instead of the watch.
I'm still getting used to life having to sift through the menus to disable and enable radios but you're right. There needs to be an easier and faster way.
