[Q] Lost 30% of battery in 2 hrs.

Is this kind of performance normal with Android?

What ROM are you running?
How much were you using it?
How many Widgets are you running?
I know I'm running an OC i9000 kernel with a live wallpaper - so my battery life is pretty horrid.
And if your coming from a non-android phone? The battery life will be a lot worse then what you are used to. Between the AMOLED screen and if your running a custom ROM battery life will get worse.

What ROM are you running?
- Cognition.v2.3b8/Launcher Pro
How much were you using it?
- moderately
How many Widgets are you running?
- Beautiful Widgets (Weather/Time), Google Search, Google Voice, Launcher Pro Calendar
And if your coming from a non-android phone?
- Came from iPhone 3G
Other Apps: Lookout, tasker, advanced task manager

One suggestion: You don't need ATM. Android can manager the memory quite well.
And no, this performance is NOT normal. Did u try recalibrating the battery?

Yup.. loose the task killers/task managers - that will cause you more battery woes than anything. Especially if it's trying to kill a task/application that just sit there and restarts - causing a nice infinite loop of battery death
I came from a 3G as well. Had to re-think on how to use my phone. The greatest thing about Android and its hugest fault.. is you have to manage everything yourself pretty much.
I would suggest turning off basic processes while not in use (wireless, GPS, and even synching)
Also dimming the screen even just a little bit will help.
Beware that most of the ROM's out today (including Cognition unfort) are terrible with battery life. Most of it is related to i9000 ROMs being on Captivate devices and are horrid at power management.
BUT.... even if you were on a Stock ROM you will notice less than stellar battery life with your device vs. the 3G.

I am experiencing similar shock to X10D3. I am coming from an iPhone 3G with my work email being pushed. I am currently running Assonance 5.0 with my work email still being pushed. I wiped battery stats using clockworkmod, turned brightness to minimum, have removed the calendar and news & weather widgets, so that the only widget I have is picture frame (and it is not running on the main screen). Additionally, I changed my wallpaper to a near-black one and only have 4 icons on my homescreen. I also keep wifi, BT, and location services turned off.
I am currently at 88% after being unplugged for about 2 hours. All I've done on my phone is play Word Feud for 5 minutes, check my flight on FlightView, and read a few emails.
With my iPhone 3G, I could have easily gone an entire day without having to plug my phone in. However, with the Captivate, I find myself having to plug in after 12-15 hours, even with what I consider to be pretty moderate use.
One thing that was mentioned is that these custom ROMS tend to be battery hogs. Would I be better off (battery-wise) running the stock 2.1 that came with my Captivate? How about if I ran 2.1 but just rooted the phone to eliminate all of the AT&T bloatware that may be running in the background?

On a day of moderate usage with about 1-2 hours calls and about 1-2 hours screen being on, system up time at about 12 hours, I have my battery at about 50-60% by the time I am home in the evening. I talk on phone on my car bluetooth most of the time.
I have two gmail accounts set to push, and google voice set to push all the time.
Auto-sync is constantly on.
Brightness set to minimum since I am not in sun most of the time.
No task killers installed, nor have any CPU speed reducers or anything like that.
But one thing, since I don't stream data so heavy (EDGE is fine for my email/xda/chatting), I am on EDGE all the time.
The ROM I am using is in my signature.
EDIT:
My phone stats today till this minute
Time since off charger: 5 hours 30 min
Calls: 29 min 2 sec on bluetooth (I turn bluetooth off when I am not in my car)
Display on: 1 hour 25 min
Sync accounts: 2 gmail, 1 google voice
Weather widget set to refresh every 4 hours
Brightness: 0%
Network: EDGE
Battery at: 70%

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.

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

@Geezer; thanks fire posting all those tips. Many I had not thought of.
@th3ory; hopefully something will come from this thread that assists in development.
ANY OTHERS? The developer is obviously cognisant enough to monitor these threads and take consideration. Put in your two cents.
Is anyone using the corporate email app with an exchange account and having GOOD battery life?
Is anyone using 3dchainfire (or any of the others mentioned above) WITHOUT irregular battery drain?

I installed the ice cream theme posted in the theme section and unl3ash3d 1.4 at relatively the same time.... I love the theme, but if that is causing battery issues it's gone.. My battery drains drastically now(down to 85% in an hour). when I was running1.3 with adw ex I was at 14hours heavy use...going to my nandroid to see what happens.
no other mods or apps..

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:

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.

Droid 4 battery issues...unbearable.

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

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

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

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

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

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

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

I have wifi permanently off...
I have 4g almost all the time.
I use a gmail, but I cannot find a way to limit it's syncing...I still want it to check for emails, I guess just not as frequently.

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

Battery Stats - non rooted

Is the battery life really that good? I really can't get more than 2 hours of SCREEN time with broken use or 3 hours of concentrated use. The International had a thread about this, but those are GSM and running custom ROMs and kernels.
Post your crazy good (or bad) battery Stats here with setups and sync settings. Stock non Rooted preferred, but maybe someone here can convince me to root my phone again!

I'm having the same problem

I'm currently rooted running d3rp but when I've had it stock I get pretty great battery life. Definitely no complaints. Maybe a hardware issue with some phones?

I get about four hours on screen time. And twelve standby. It's enough to get me through the day, and I'm alright with that.

How did you achieve that (settings,apps,etc...)?

I'm apparently an idiot and my brain is fried from work today, but where do you check the screen on time?

I'm on derpone. I uninstall everything I don't use (Facebook, Twitter, chrome, ect), turn off auto sync, I'm also on the experimental x kernel, unlocked to 1.5ghz, under volted, and have thermal throttling set to the highest (coolest?) Setting. Oh and I have the battery saver on, everything is enabled aside from the brightness control.
...wow I do a lot of stuff.

HTC took it out of the stock settings, the only way to see is with a battery monitor like better battery stats.

Is Gsam a good monitor? I have power saver off (I see no real difference in battery life) but the screen uses like a maximum of 10% of my power. The kernel uses like 25%. Apps account for 75% of battery usage.

You've probably already searched some if you're asking, but I wanted to make sure you have seen this thread:
http://forum.xda-developers.com/showthread.php?t=2249497
It includes my tip that turned me from disappointed w/ battery life to impressed. (By setting every social app, blink feed, weather, (but not calendar, gmail, or other google services)) to manual sync... and my phone lives most of its life in below average signal strength areas.
Otherwise, I'm running non-rooted, stock, and no battery tweaking apps, or memory freeing apps, etc.

How do I make sure only my google stuff auto syncs? I could care less about the main facebook app. (I need the messenger though, lol).
If I uncheck everything in the Facebook section of Accts and Sync, will it sync at all? Like, when I run the app?
But if GSam is right, then my main problem is the Android Os and kernel. Together, they eat up about 30% of my battery, sometimes more.

Yeah, that's it, you got it. Settings > Accounts and Sync.
My theory was the phone would never be able to turn itself down to a lower power state since one thing or another would always be keeping the data connection active. Used to barely clear 1 day, and now 2 is no problem.
Apps with sync off just update when you open them. Made sense to me!
Good luck.

I have wifi always on with "data connection" unticked and "Sleep mode" ticked because I seen this from htc's website "Keep in mind though that the Sleep mode option for the data connection in Settings > Power, when enabled, overrides power saver mode." Here are some screen shots my brightness is manually set at 20%.
