[Q] Read battery log after restart

I have an issue I'd like to debug, but I need some information to help myself:
I charge my SGS (JM1) in the evening, when it's 100% full I disconnect the charger and go to bed (23:30), phone switches to airplane mode at 24:00. When I get up 8h after, my phone is off and has absolutely no battery left.
This happens every now and then, IMHO there's no app causing this (haven't installed anything lately). I can't reproduce the issue.
How would I best debug this and try to find out what's causing the battery drain?
Can I still read the battery log after a restart?

Don't see Amy bad apps.
You can.use sgs toolbox to see the battery usage is.
Some make the phone almost never go in powersave mode.

Thank you so far.
I looked at the battery usage stats and saw that bluetooth was enabled for more than 7 hours (although it was disconnected). That IMHO shouldn't have completely drained the battery though...

I am seeing the same problem recently; the battery drains out really quickly in no time even when there are no major apps running. Even the battery usage menu shows nothing major. During this time I have noticed that the phone gets really hot and the battery indicator app shows that the battery temperature as b/w 40-50 C (its around 25-35 C when there is no issue). During this time I can't even make calls or send/receive SMS!!! Seems that it just cannot get a network signal.
There were no such issues for the last couple of months. I can't imagine an app directly or indirectly causing this.

If an app keep the phone awake all.the time and use wifi/Bluetooth/gps it will drain the phone fast.
The only solution is to find out where the flaw is.
Personal i would backup the phone and do a complete wipe/ reset of the phone so it will be clean and like new. Then i would test to se if it drain the battery.
If it does then it is broken and need a.repair. Else i would start to intake the apps i need, but looking close what they do.

Have you installed any lagfixes recently? When I had voodoo lagfix on jg4 I would get at best 8 hours of stand by time. As soon as I flashed jpm I get 1% drain per hour
Sent from my GT-I9000 using XDA App

I have not installed any lagfixes, my phone is on stock JG4 firmware. The battery life is otherwise very good, only at times (very random) the battery starts draining from 100% to 0% in a matter of few hours.I use System panel to check if there is any app that is causing this, but it does not indicate anything like that.
The only thing that I can think of is that the phone for some reason looses network (I can't make a call and send/receive sms during this time) and keeps trying to reconnect without success and hence drains out the battery. Once I reboot the phone everything becomes fine and the battery usage becomes normal. Is there any way to find out that the phone is trying to connect to the mobile network and this is causing the battery to drain out?

Neither do I, never used any lagfix so far, I'm on stock JM1.

That's possible but I don't know how to log this...
Gnarf, it just happend again. Before going to work it was all normal, now it's frozen.
I connected it to my computer, but WinXP recognized it as an unknown device.
ADB doesn't work, else I had pulled the logfiles.

maybe u should consider upgrading to JM7 or JM9. and before installing apps do a full reset and cache wipe.

I'm waiting for CM 6.1 to sort it all out, given that "FroYo by Samsung" still isn't what I expected it to be - at least judging from the betas.

Battery sucking down fast

I've got my autonootered 1.1.0 NC and it is working great. The only thing is the battery seems to be running out really fast on this. On my wife's autonootered 1.0.1, the battery isn't running out nearly so slow and we have all the same apps, although some of mine, since it's newer, may be more recent versions.
One thing I noticed is that she has very little time on "Android system", whereas 2/3 of the drain on mine is from that. The only apps that typically run though are advanced task killer and batter indicator. I regularly shut down everything else.
I've also renamed phone.apk and the telephony(something).apk on both of them as well.
Is there anything that will deep dive into "android system" on battery use? There are no rogue apps running (at least according the task killer). Or any suggestions?

First thing I'd suspect are live wallpapers followed by widgets. Verify that you have a plain wallpaper and remove any widgets that you would anticipate are doing frequent polling of any kind. I'd remove that battery indicator one and see if that helps.

Running zeam with plain nook wallpaper (just like on my wife's nook). No widgets. Am seriously wondering about the battery use thing though.

Like I suggested, uninstall that battery indicator app. You didnt mention which one it is so for now based on the only info youve provided thats the only advice I can give.
In one test I did on my nookie froyo install I'm running, I tried a new spruced up kernel and ran a battery status widget. The widget caused the nook to stay out of deep sleep and also out of lower clock speeds when idle resulting in horrible battery life.
Are you running setcpu on either or both nooks and if so are they set the same?
Sent from my nook color using Tapatalk

Try systempanel lite task manager by nextapp in market. It might help show ram and cpu usage of things.
Sent from my nook color using Tapatalk

When not using wifi turn it off. That will save you some battery life as well.

Keep the suggestions coming
The battery app is "battery indicator". It is usually running on both nooks, but mine has a more recent version I think (this is my main suspect right now).
We always kill the wifi when not using it, so I know that's not it. Also not running setcpu on either.
I sucked down probably 5-10% while just reading with only "advanced task killer", "battery indicator", and the stock reader running for less than an hour last night.
I'm going to try systempanellite and see if that tells me anything. Also going to charge it up to 100%, boot into CMR and reset the battery stats.
If it is the battery app, wondering how to find the older version to downgrade to, or maybe just find a different one, I suppose...

45 minutes of simply reading and went from 99% all the way down to 88%. No battery utility. Systempanellite (only running for a few of those minutes) didn't really show anything sucking either.
Only other difference I can think of now is that I disabled OTA updates on my wife's nook.
I wonder if I just got a bad nook, battery wise...

So ~10% from about ~1 hour of use? Might be a little high for just reading, especially if your brightness is low and your wifi is off. However, I note a 10% per hour discharge with average use. I get about ~2% or so overnight loss with screen off and wifi off.
Rooted 1.1, Monster root pack. Overclocked with Dalingrin's kernel.

Looking at the two nooks, side by side, I notice that on mine, AFfileDownloadService and CloudService are background, while on my wife's, they are 'Service'. When DeviceManagerService is running, that is also background on mine and service on hers.
Could that be why the "Android system" is sucking so much battery? SystemPanel doesn't show anything sucking cpu....
I know it's supposed to be around 10 hours, but that works out to be about 7 hours reading a small, simple epub, which has me concerned.
I did lower the brightness on mine to match my wife's exactly. It was less than halfway, but heres was lower, right in between the two esses at the end of 'brightness'.

A more deliberate test shows 1% drain every 5 minutes (almost exactly) while just reading. That's a little over 8 hours and still less than I expect. Maybe I need to tweak the brightness a little more...

Another UNL3ASH3D battery investigation

ANYONE USING THIS [email protected]$$ ROM, YOU'RE INPUT IS VALUABLE.
It seems some are having the problem and some are not. I think for a community as strong as we are, it should NOT be too hard to figure this out.
**If you are having battery issues, please post anything you have done to you're phone that is not standard in the ROM. (i.e. Apps you've downed, mods you have done, etc)
**If you are not having issues, look over these lists and verify, by saying "Nope, it's not that app/mod because I've done that and am not having issues"
Just to set a standard, if you are seeing 12-18 hours on standard battery with moderate to high usage, you are NOT having a battery issue... This device is dual core, 4g, miniature computing giant.
If you, like many of us, are seeing >10% an hour with no usage (i.e. Battery dead in 7-9 hours), you do have a battery issue.

I'm experiencing this issue as well. I am running UNL3ASH3D v1.4 with the following modifications:
BLACK SWYPE/GMAIL (although the black gmail didn't work with mod like it did with v1.3. Swype is black though and working just fine. just a side note.)
I've reflashed v1.4 at 100% battery after wiping cache, dalvik, and system /system followed by a RESET of battery stats last night around 1am CST.
Hope this helps. I will try to follow this thread to contribute as much as I can.

I was getting 15% an hour on standby...But I ran the calibration, and now im getting 12 to 14 hours with normal usage.
I will say this to people...In the beginning, whenever I tried the calibration, it wouldn't do anything. After trying a few times, I noticed that after I did teh calibration, I had to wait about 2 to 3 days, til I noticed an increase in performance. Not sure if others saw this...

I went back to debloated rom. My battery drain was bad on extended battery. Now its back to getting all day moderate to heavy use and still have 30% or so before nighttime charge.
Rom is sick dont get me wrong. Something is just not right with the battery stat.
Sent from my DROID BIONIC using Tapatalk

I am on UNL3ASH3D 1.4 and I have the extended battery. After a day of moderate to heavy use I had 60% left at 11PM last night. My battery life is excellent. Here's the advice from NoBloatware (at DF) that I followed:
consider doing a factory reset. Do not sync apps, wifi connections, etc. with Google services as that may cause a problem. Install all apps and wifi connections from scratch. A bit of a pain, but not too bad.- install a home/launcher replacement. I use Go Launcher EX, which is free, and I love it. No reason not to try out an alternative launcher as you can always go back to how you had it.
- don't use an automatic task killer--not even the one that comes with the phone. Reboot your phone and look at what's running. If anything that you've installed is running and there's no reason for it, then uninstall it and find an alternative that behaves. Ignore any stock apps that run on boot as I've found them to be more or less benign.
- weather widgets, live wallpapers, news/social feeds, any app or service that you use that runs--do without it if you can.
- don't use antivirus
- the DLNA app pops up a dialog box that will set your WIFI sleep policy to never. The default is "turn off when screen turns off" and I personally think that this setting is the best thing for battery life. Under wifi settings view your connections then hit menu to see "Advanced options" where you can set the sleep policy
- if you have access to wifi, leave it toggled on as it is more efficient than 3G. This is different from the sleep policy.
- I leave GPS toggled on too by the way. Apps use it as needed. When I'm done with Maps or an app that uses it, I'm sure to return to the home screen so GPS can stop. Under wireless settings turn on "Google location services" so that an app is able to use network resources to get your location instead of GPS. I have "VZW location services" turned off--don't know why that option is even there. By the way, I increase the speed of voice output > text to speech > speech rate because I like the directions to get spit out faster. That saves a bit of battery. Turning off the display and just listening for directions help. Also, often I just get the directions and then exit back to the home screen: GPS uses so much battery I try to get it over with ASAP.
- when you get a new battery, do a factory reset, or an OS upgrade run your battery all the way down until the phone shuts off and then charge the battery all the way up. This will callibrate the phone's understanding of the battery's capacity. Do this once every month or two also, but don't do it too often if you can help it.
- I have my battery set to "Performance Mode" and data is on all the time because I am on call 24x7. If you don't mind, try out a more conservative battery profile to save more gobs of energy.
- set screen brightness to "Automatic"
- under Accounts, click on any account listed and turn off sync for any items that you're not interested in syncing. For example, Google Books if you don't use it. Don't use Backup Assistant--I prefer syncing my contacts with Google. You don't need both. Also go into your contacts > menu > display options > backup assistant > UNCHECK. Also do contacts > menu > more > settings > contact storage > and select your Google account and "remember this choice"
- if you never use bluetooth then toggle it off. If you do use it sometimes, it's fine to leave it toggled on all the time.
- consider turning off voice privacy. This may not be a big deal but it will save some processing (and therefore battery). It may also improve call quality.
- turn off haptic feedback, animations, and any un-needed sounds in Android settings and in your apps
- set your screen timeout to as low a time as you can stand (I use 1 minute) and manually turn the screen off when you're done using the phone. I use an app to lock the screen so I don't wear out my power button...as happened on my original droid.
- turn off in-pocket detection
- keyboard: turn off vibrate on keypress and sounds for any keyboards you use
- use a red screen background. On the original Droid screen--not sure about this Droid 3 screen--red was the most efficient color that could be displayed. Anyone know if this still holds true?
- camera app: i like keeping location on and flash on auto. Consider turning location off or at least returning to the home screen ASAP when using camera if location for camera is on.
- in stock browser the default home page is Google and it uses your location. This is a bad idea as it can waste your battery for no reason. Make something else your home page and make sure to close any web page that uses your location when you're done viewing it.
- charge your phone via the wall charger instead of computer USB as it is faster. Also, don't use long USB cords--use regular power extension cords instead. I stick with the charger that came with the phone.
In addition to those suggestions I also do the following:
1. Emails: I don't know what email app you use, but try this. It saves battery power and in some cases emails arrive quicker. This scheme will have you using only the Gmail app on the phone for all email accounts whether they are pop3 accounts or Gmail. Go to the Google Gmail inbox on your computer and log into the Gmail account. On the top right of the screen is an option called Settings. In there is an option to have the Gmail program poll your regular, non-Gmail accounts (From the inbox; Settings/Accounts & Import/ Check mail using POP3). Provide the email address and the password. The Google Gmail program will then poll your other accounts on a frequency from 1-5 minutes and push the email immediately to your phone. The polling frequency is determined by each account's activity - more emails = faster polling. This saves battery power because on the android OS pop3 accounts are polled at a frequency of 1-30 minutes and that really eats battery. Because the phone goes and checks those accounts for mail whether there is mail there or not.
2. If you are using Live Wall Papers, stop!
3. Use wifi any time it is available. It uses a lot less power than 3G and it is much faster.
4. If there are widgets that automatically update (facebook, weather, etc.) change their update frequency in their settings menu. Set them to 30mins or 1 hour.
5. If you use an Ad Blocker, turn it off.
6. If you are using Launcher Pro, try Zeam or Go or QQ.
7. Reboot the phone once per day.
Good luck.

I have the battery issue
I have the battery issue and the only apps I have that would maybe affect it would be juice defender (which I thought would improve battery life if anything) and chainfire 3d. Those are the only apps that I have that I would think are an issue. I only get maybe 6-8 hours of battery life and I am running Unleashed V1.4.
P.S. Geezer I don't think everyone has to have those exact settings to get a good battery life, not to mention no one wants to spend the time doing all that BS when its an issue with the ROM somehow because when flashed to stock ROM no problem.

Why the battery issue only effects some.... No idea. I really believe it is a app that is not playing well that the ones having issues have in common.
I have been on stock for the day after the debacle last night, and it is the first time I had to use my car charger... Really I don't one. But.... a preventive measure is a battery script that I am adding to the init.d in 1.5. I am really hoping it helps those having the issue.
There are 3 things I have always accomplished in my ROMs ... Great battery life, zero lag, and fluidity. 2 out if 3 isn't bad.... But I want the trifecta. Lol

Is anyone using 3dchainfire (or any of the others mentioned above) WITHOUT irregular battery drain?

I had the 100%-charge-to-dead-in-6-hours voodoo on me since v1.4 came out until last night. I factory reset, reinstalled and have been adding an app every few hours since this morning. As of now, I am getting FANTASTIC battery life...
I am currently at 19H 49M on the STOCK battery, with 31% remaining... That's with 6 of those hours running WI-FI, almost 4 hours of display time on. Yesterday I'd have charged three times for that many hours.
As of now, I've reinstalled the following apps:
RomManager
Titanium BU
GoLauncher
Beautiful Widgets
ES File Explorer
Handcent
K9
XDA Prem
Multiple GO Themes
All of these seem to be behaving pretty well together so far. I was going to add the extended battery tonight, but the results so far make me want to keep riding the wave one app at a time with the stock battery so that I can get an apples to apples comparison. Honestly, several of the apps I've already reinstalled are among those I considered likely culprits. If I can even APPROACH battery life in the long run such as I've experienced today I will be ecstatic.... LOVE THE ROM!

Hey all, I am _NOT_ having a problem, getting 2 days out of mild use and 1 full day (18 - 20 hours) out of moderate use.

Dood. This is really some great news. I still have the voodoo but I'm hopeful. I did the battery cal this afternoon at full charge and it's just now going fully dead. I was going to see how it worked out for a few days but looks like the ROM is being updated and I'll be flashing again tonight.
Do you have any apps frozen or removed?
How did you do the battery calibration? Does the factory reset include the stats?
I want to emulate what you have done.
Still curious about exchange accounts. Anyone NOT having a battery issue that uses a corporate email?

I've not uninstalled or frozen ANYTHING - I've intentionally been minimizing any variables, hoping to isolate an app or app-combination which is delivering the hit.
My process was:
-Full factory reset.
-Flash v1.4 per DT's instructions (wipe cache/dalvik, format /system).
-Wiped Battery Stats via recovery
-Booted up (already charged to 100%), then unplugged and let her rip, installing
the apps listed above 1 at a time every couple of hours.
Haven't change anything else at this time. As far as battery calibration, all I've done is wiped stats and and letting it full discharge - so no real "calibration" to this point.
Can't help you with the exchange issue, only sync'ing 4 exchange accounts.
ETA: I realize that much of the wiping/formatting was redundant after the factory reset, but it only took a minute or two, and I wanted to start as clean as possible. I'm not entirely up to speed on the mechanics behind each element.
One thing I noticed was that prior to this my battery info screen showed a solid blue bar for "awake", it is now a nicely "dashed" line properly coinciding with actual time used.

lots of apps but "always running" google music, WSJ, SMS popup, battery indicator, photobucket, advanced task killer
"mods" = root
extended battery, moterate usage = 70% in 3hours

I have the problem, and it seems to have become worse since I recalibrated the battery (twice). I'm running UNL3ASH3D 1.4 (which I love, BTW) with no modifications or task killers. OFC, I haven't tried all the battery-maximizing tips listed by Geezer Squid, but IMO if you have to disable half the features of the phone to get a day's standby, something isn't right.

Running Unleashed 1.5, fresh install, im down to about 85% after 20 minutes. Only installed ADW launcher EX

I am back to stock deodexed. I'm going to recalibrate the battery, do a couple complete backups, and then try flashing 1.5 after completely wiping the device. Maybe the regular sequence (cache, Dalvik cache and /system) is not enough?

Extreme battery drain on extended battery

Please bare with me, I am a fairly novice xda user.
I purchased my Bionic at launch, and it has been working perfectly until about a week ago. I always run the phone on stock OS not rooted, automatic brightness, 4g turned off, no wifi/sync/bluetooth. I would generally get down to 20% of my battery from 7 am to midnight on these settings, which was fantastic.
Suddenly, I now lose 10% every 20 minutes. This is not an exaggeration, I have been testing it with Battery Spy. CPU Spy reports that my phone never goes into deep sleep and is always running at the lowest mhz setting when idle.
Under battery usage, Cell Standby is reporting 45%, then Phone Idle at 35%, then Screen at 15%. The remainder its split between K9 Mail and Handcent SMS.
I have uninstalled everything that I thought could be causing this... Facebook, Google+, etc. Apart from the stock bloatware and k9/Handcent, my phone is like new. The best I could do is a factory reset at this point...
I don't think it is a bad battery because the stock battery goes from 100% to 0 in less than an hour when it would last half a day beforehand. I am really at a loss.
One thing I do know is that the 3g and bars are almost always blue, which I think it means is transmitting data. Maybe this is the culprit?
Please pardon my ignorance with the whole issue. Any help would be very, very appreciated. The Bionic was the best phone I have ever owned up until this battery fiasco, and I would like to find out why this is happening.
Thank you.
EDIT: would just like to update, Battery Spy reads that my phone is running at 104° Fahrenheit. I do not know if this is normal, but this was after an hour since a cold boot. Sounds high to me but I'm not sure.

Sounds like you have some thing that is really using up some cpu cycles. One way to see what's going on is to install the app Android System Info from the market. It has a section called Tasks and it will let you look and see what part of the system is using how much cpu. I do not think you have to be rooted to use this, but I could be wrong. I did go to the market and look and saw no mention of needing to be rooted.
I know this will sound extreme, but I would definitely do it if this was happening to my phone: Factory Reset and start fresh.
Good luck.

Thank you for the advice. I installed it, and appear from the Android System Info app taking up 50% of my cpu, and Android System using 4%, everything else was listed at 0.

Well, that didn't help much. Oh well, I would definitely do the Factory Reset then. Again that's just the way I would handle it as something is going on with your phone that wasn't happening earlier. Just go to the Privacy settings and make sure you have Backup and Automatic Restore checked. If your launcher has a backup feature, go to preferences and do a backup of the launcher settings. Then do the Factory Reset. It's a pain to have to setup everything again, but a reset really does cure a lot of ills that pop up.
Good luck.
Oh BTW, here's some general Battery saving suggestions:

Turning off the display and just listening for directions help. Also, often I just get the directions and then exit back to the home screen: GPS uses so much battery I try to get it over with ASAP.
- when you get a new battery, do a factory reset, or an OS upgrade run your battery all the way down until the phone shuts off and then charge the battery all the way up. This will callibrate the phone's understanding of the battery's capacity. Do this once every month or two also, but don't do it too often if you can help it.
- I have my battery set to "Performance Mode" and data is on all the time because I am on call 24x7. If you don't mind, try out a more conservative battery profile to save more gobs of energy.
- set screen brightness to "Automatic"
- under Accounts, click on any account listed and turn off sync for any items that you're not interested in syncing. For example, Google Books if you don't use it. Don't use Backup Assistant--I prefer syncing my contacts with Google. You don't need both. Also go into your contacts > menu > display options > backup assistant > UNCHECK. Also do contacts > menu > more > settings > contact storage > and select your Google account and "remember this choice"
- if you never use bluetooth then toggle it off. If you do use it sometimes, it's fine to leave it toggled on all the time.
- consider turning off voice privacy. This may not be a big deal but it will save some processing (and therefore battery). It may also improve call quality.
- turn off haptic feedback, animations, and any un-needed sounds in Android settings and in your apps
- set your screen timeout to as low a time as you can stand (I use 1 minute) and manually turn the screen off when you're done using the phone. I use an app to lock the screen so I don't wear out my power button...as happened on my original droid.
- turn off in-pocket detection
- keyboard: turn off vibrate on keypress and sounds for any keyboards you use
- use a red screen background. On the original Droid screen--not sure about this Droid 3 screen--red was the most efficient color that could be displayed. Anyone know if this still holds true?
- camera app: i like keeping location on and flash on auto. Consider turning location off or at least returning to the home screen ASAP when using camera if location for camera is on.
- in stock browser the default home page is Google and it uses your location. This is a bad idea as it can waste your battery for no reason. Make something else your home page and make sure to close any web page that uses your location when you're done viewing it.
- charge your phone via the wall charger instead of computer USB as it is faster. Also, don't use long USB cords--use regular power extension cords instead. I stick with the charger that came with the phone.

Please bare with me, I am a fairly novice xda user.
I purchased my Bionic at launch, and it has been working perfectly until about a week ago. I always run the phone on stock OS not rooted, automatic brightness, 4g turned off, no wifi/sync/bluetooth. I would generally get down to 20% of my battery from 7 am to midnight on these settings, which was fantastic.
Suddenly, I now lose 10% every 20 minutes. This is not an exaggeration, I have been testing it with Battery Spy. CPU Spy reports that my phone never goes into deep sleep and is always running at the lowest mhz setting when idle.
Under battery usage, Cell Standby is reporting 45%, then Phone Idle at 35%, then Screen at 15%. The remainder its split between K9 Mail and Handcent SMS.
I have uninstalled everything that I thought could be causing this... Facebook, Google+, etc. Apart from the stock bloatware and k9/Handcent, my phone is like new. The best I could do is a factory reset at this point...
I don't think it is a bad battery because the stock battery goes from 100% to 0 in less than an hour when it would last half a day beforehand. I am really at a loss.
One thing I do know is that the 3g and bars are almost always blue, which I think it means is transmitting data. Maybe this is the culprit?
Please pardon my ignorance with the whole issue. Any help would be very, very appreciated. The Bionic was the best phone I have ever owned up until this battery fiasco, and I would like to find out why this is happening.
Thank you.
EDIT: would just like to update, Battery Spy reads that my phone is running at 104° Fahrenheit. I do not know if this is normal, but this was after an hour since a cold boot. Sounds high to me but I'm not sure.

i have the same problem man! i have the extended battery and it lasts maybe 9 hours and i have tried several batteries from verizon store i keep swapping them lol and im on 4G all day and performance battery and data on all 24/7 too and i could get 20 hours ++ out of thunderbolt extended and cant get half that with bionic. there is something going on and nobody at verizon can figure my problem out!

Format the sd card in ur pc. Then put sd card back in bionic and transfer ur stuff back on it. Ur bionic is scanning sd card non stop for errors drainin battery. I had this problem for weeks beofre i figured this out. Was gettin 7-8 hrs on ext battery. Now ibget 30 hrs

I had a similar issue and the problem was my sim card needing to be reinstalled. It was not seaded correctly and caused my radio to act up. I truned off the phone and removed the sim card and then reinserted it and rebooted and I was back to normal.
I am not sure if this is your problem but it is easy enough to try.

Would this apply if I am not using 4g? I have 4g disabled and it was my impression that the sim card was only used for 4g.
I uninstalled k9 which for some reason began using 7% of my battery though I had never opened it since reboot and now I am getting a loss of 10% per hour of normal use.
I went to bed with the battery at 70 and woke up with it at the same so I at least solved the sleeping problem. Not sure why k9 was responsible though.

Battery Drain After Stock 2.3.5 Gingerbread Update

I've been looking everywhere and tried multiple methods to try and fix the following problem but without any success... please help!
I have a stock captivate which came with 2.1, upgraded to stock 2.2 last year, and just last week upgraded to stock 2.3.5. Never rooted or anything like that.
Up until last week, while I was still on 2.2, I had fantastic battery life, draining maybe 1% per hour when idle. After the update to 2.3.5 I'm now draining 10% per hour when idle. I've tried different watching apps to try and catch a culprit but I'm at a loss to point to anything. All the apps I'm using are unchanged from when I was on 2.2. My best guess is that it has something to do with wifi.
When I left the phone untouched on idle last night it showed 30% wifi and 25% cell standby for battery usage. My wifi sleep policy is set to never which is what I had on 2.2. I leave wifi on all the time, but I left it on all the time with 2.2 without any of these issues. I have 5 bars and am located near a cell tower so that isn't any different either.
I've tried factory reset as well as a couple cycles of draining the battery all the way down and filling it all the way up without any change. From a UI standpoint, I like the new Gingerbread update but 10% drain/hour when idle compared to a couple days when idle with Froyo makes the phone much less usable... Help!!

You could have an app that is running in the background taking up alot of ram and or CPU peformance. This can cause your battery to drain faster. Having a live wallpaper as well as apps that update in the background will also shorten your battery life.
however, there are many apps out there that monitor what the other apps on your phone are doing and will let you know if there is a rogue app taking up battery. Also, if you have the stock battery look into a new one. Its probably old by now and somewhat tired out.

I had the same battery drain issue upgrading to froyo. I ended up finding a custom GB rom and the battt drain slowed but is still faster than the stock rom. All apps have stayed the same since day 1. At this point I'm afraid to touch it again since it the wifes, and was a bit upset about the last time.

This was happening to me when I updated to GB but found it was one of the apps(No LED and Vlingo). I uninstalled and then reinstallled them and it stpped draining as fast in idle. I would also suggest getting the 1800mAh OEM battery for the Epic 4g Touch. It works great in our phones with 15 to 20% more life.

email app draining battery
I also updated few days ago to gingerbread official UCKK4 and after that my battery drains at around 5pm, whereas before it was around 11pm with froyo.
the battery log says email app is sucking it up. the email accounts are exatly the same 2 I had before: hotmail and company both configured as exchange.
Solutions?
thanks!

It seems like a lot of people are complaining of issues after the update. The most reliable solution would be backing everything up and performing a factory reset. Just be aware that when you do it, you will lose EVERYTHING on your phone that isn't already backed up somewhere else so make sure you grab your pictures, music, contacts that aren't already backed up in an email address, etc.

I did perform a factory reset after the update!
I have nothing on the phone, except few apps, which I quickly reinstalled.
The emails and contacts are on hotmail so, it wasn't a concern they get reloaded from the exchange contacts sync. music was on my external sd card.
the problem is that if I disable email, battery is fine...but, c'mon...then what's the point of a smartphone! and if I disable background check, it's also fine, but again, what's the point of a smartphone!
I am really concerned now... with this battery life is unusable.

We have two captivates in our house, mine and my wife's. For mine, I did a complete one-click flash back to 2.2 froyo and then immediately upgraded to KK4 through Kies. Overall, my battery got much better and gave me a good 4-8 hours more battery life than what I was getting. When I go to bed I'll still have 30% remaining.
Now the bad news: My wife's went the opposite. On Froyo she had better battery life than I did and she updated without flashing her phone. On GB her battery was dying in almost 4 hours, 6 hours at best. It was crazy. On Friday I took the phone, backed it up and performed a Factory Reset. For two days this gave her better battery life than 4 hours but still horrible. Maybe 8 hours total.
What I noticed:
Over the weekend I paid close attention to her phone. I noticed the 3G symbol would be displayed on the screen while she was also connected to wifi here at home. Then I noticed that her email app (not the gmail app) was the #1 use of battery, even over the display. Clearly something was wrong. Then I noticed if I opened the email app, it would result in a connection error. However, if I opened a browser or the marketplace everything worked normal.
My thought process is: the Email app is constantly trying to connect to its server and since it's unsuccessful it continues to retry non-stop draining the battery.
How I might have Fixed it:
I took her phone and put it into Airplane Mode.
Waited a couple minutes and turned on WiFi only. (Phone was still in airplane mode)
Waited a minute and then turned WiFi off.
Took phone off Airplane mode. When everything came on, the WiFi was still off since I manually turned it off while in Airplane mode.
Rebooted the phone, WiFi is still off.
Turned on WiFi after everything finished running from boot up.
Noticed that now the 3G symbol was gone when WiFi connected.
Today she unplugged her phone at 5am this morning. As of 4pm her battery has only dropped 25% (showing 75% remaining). I checked the battery usage and the Email app is back down around number 6 or 7 on the list. Not sure if that's what fixed it but the battery is a HECK of a lot better than it was before. If someone else sees these similar symptoms give it a shot and hopefully it will help.

I was having the same issue on my phone after upgrading to GB. The 3g would stay on (displayed) while I was connected to Wi-Fi. It seemed to be draining my battery. It is better after doing a cache wipe. Next, I'll be swapping modems and kernels until I find a better combo. Currently, KK4 with corn 7.06 (sio & conservative)

Interesting, I don't have wifi at home, but I also noticed at work (where I have wifi) that 3G and wifi icons were both on.
I am not sure I can reflash the phone, and I could try to reset the phone again.
I will try your "procedure" and see what happens.
1 more thing: as I said in my prev post, I use hotmail with both SSL checks, as exchange server.
additionally the other account, which now is disable (my work account), is a zimbra 7 server with again both ssl checks, and configured as exchange.
the same configuration was working on froyo.
my system is not rooted and nor modified. out of the box install.

Problem identified
I identified that the problem is the hotmail account.
I factory reset the phone again and cache wipe, then I did not install any app, apart from those which auto-update themselves.
I configured my zimbra 7 work email account (exchange activesync): waited few hours. Normal battery consumption.
Reset the phone again, then this time I setup only hotmail: battery drain.
solution:
now I am using stock email app for work account and downloaded hotmail app (seven+microsoft) which still allows me to sync contacts and calendar. It's suboptimal (i'd like to have all in 1 place), but battery consumption seems back to normal.

problem present again
Sorry, but after few days I realized the problem is still there...also using only zimbra (activesync exchange).
no solution yet. hotmail using its app seems fine, but no way to use stock email. after a while it starts again consuming > 25%

Correct me if I'm wrong...
So yeah correct me if I'm wrong, but I read somewhere that your Data connection and WIFI drain the battery quite a bit. I think I remember using something with a 2.2 ROM once, where if my screen was off, it basically shut off everything except the ability to receive calls and texts. I'm not really sure because that was months ago, but if this rings a bell to anyone, I wouldn't mind knowing too!!1!

Original poster here... After doing another factory reset, I only installed a few apps a day over the course of a week, waiting for the battery issue to reappear. Through this long process, I identified the Kayak and Facebook apps as the battery hogs. When I had everything else reinstalled except for these, I had the same or better battery power compared to Froyo. I contacted Kayak who said they were aware of the issue and just put out a fix. I think the problem was, an update for Kayak came out around the same time that I performed my upgrade (or the battery issue for Kayak was specific to Gingerbread) so it only appeared after my upgrade. Anyway, to be working better now.
Overall, I like the stock Gingerbread upgrade, especially the fact that Swype works a lot better after the upgrade.

Email battery drain
Hi all - I am beginning a search for some solutions. I just upgraded Cappy to stock GB yesterday. Did Factory Reset before and after which eliminated the Tethering Manager issue.
Battery life at home yesterday was AWESOME. I believe this is in part because the new GB defaults to a "never sleep" policy on Wifi. It literally went from 100% to 92% in 3/4 of a day, with Wifi on all the time.
Now its Monday and I'm in the office (NO WIFI HERE) and now all of a sudden "EMAIL" is the biggest user of battery. It's been draining almost 10% per HOUR this morning. I use Hotmail as my primary email and I have it set up through the ActiveSync server on the stock GB email app (not Hotmail-specific app).
What is going on? I have the Sync set to "Push" everything, which is the way it was on Froyo and it never ate battery like that. Is it something different in GB or do you think it is something to do with this "Wifi always on" policy that somehow the stock email app is always trying to connect to the MS Exchange Server through wifi but can't? (I'd think that when wifi is out of range that it would just default to 3G "pushing" which is what it did before, and again no bad battery drain before under Froyo).
Thoughts?

Cross fingers I might have solved this. Appears that having one's Hotmail and/or GMail CALENDARS synced up may cause the problem. It appeared that both of those Calendars were basically constantly re-syncing rather than waiting for a push like the email does.
I unchecked those sync boxes for both calendars and it now seems that battery drain is slower. I'll keep watching this afternoon.
Hopefully this post is helpful if others might be experiencing the same thing. I'm hoping that it is NOT the "never sleep" Wifi because from what I've read, that is actually a battery-saver when at home in constant range of Wifi. Perhaps that is why I didn't notice this Calendar-induced drain overnight because the juice was sipping at a much slower rate even if it was constantly syncing. Once I got out onto the 3G network this morning then the juice started getting gulped......

I had the same problem after the GB upgrade for my AT&T Samsung Galaxy Captivate phone. After I read this forum, I figure the Outlook email setup would be the problem. I did the following changes and corrected the problem completely:
1. go to "settings"
2. go to "account and sync"
3. click on the Outlook email account under the "manage accounts" section
4. click on "Account settings" under "General settings" section
5. click "sync schedule"
6. change "peak schedule" to "15 minutes"
7. change "off-peak schedule" to "15 minutes"
8. click "save"
9. Done.
"Push" setting in "sync schedule" selection is the culprit causes the battery drain problem.
Good luck
