[Q] Why won't my N1 battery last more then half a day?

Hi I'm with Fido using an AT&T N1. My battery doesn't last me a full day. I thought maybe it was a defective battery, so I ordered a new one. This didn't solve my issue. I still have to charge it early in the afternoon and It's not like I'm watching video's it's just sitting there on my desk.
Anybody having the same problems or has a solution?
Thanks

Check what's using your battery, and act accordingly.

Are you on the wifis when it is at your desk? If not, how many bars of reception are you getting?

Root, undervolted kernel, more efficient roms, sync settings, apn control, brightness settings, battery calibration.
Welcome to android
Were all searching for ways to make our phones last longer/dynamic/faster.

It says 67% of use is display, I set it to shut off after 30 seconds.
The wifi and BT are off.
Another thing I find weird. I have the dock. Every time i remove it from the dock and have to draw the password pattern, it's like the screen calibration is messed up. I have to close the screen and open it to get it working properly. This also makes it impossible to answer the phone when it rings while it's docked. I remove the phone and the slide to answer doesn't work as if it's not calibrated.

Check that your CPU isn't running at 100% frequency because of some rogue app.
Check that your phone has at least a couple of bars reception.

My N1 on AT&T runs 4.5%/hr usage when I'm not actively using it, around 6% if I'm doing typical stuff with it (reading email, web, etc).
It's on 3G, rarely use wifi (it's off), GPS is on, Bluetooth is on, K9 Mail is doing Push IMAP, Beautiful Weather is updating, misc other stuff is likely updating. Tasker is running doing lots of stuff, one of them is grabbing my GPS location and uploading it to my website every 10 minutes.
No IM, Facebook, or Twitter automatically running/updating.
I don't obsess over the screen brightness, generally leave it at Auto except when doing navigation in the car (It's never bright enough during the day) and I tend to pick dark themes but that's mainly because I don't like dark-on-white themes period on my phone.

Where does it say display use is 67%? In settings> about phone > battery use?

Does your phone feel hot? I notice sometimes that I'll be walking around and my phone is like burning a hole in my pocket, not literally but very hot. I noticed that when I installed wildmonks kernel and SetCPU that my battery increased TONS.

Some general things to check:
Auto email push
Cell stand by (look at reception)
Widgets auto refreshing
CPU frequency
I make sure all of the above is working properly, and my battery lasts for 2 days with light-medium usage

Sort of related question.... occasionally, I'll have "android system" just chew through my battery....if I let it just run for a few days, or if I clear the dalvik cache, it seems to fix itself, but I'm really clueless as to what is causing this....any ideas?

Don't know, but when it happens - it means the same thing I've mentioned multiple times in multiple different threads, some apps can cause the kernel to run in loop of some sorts - running at 100% CPU speed and eating the battery very quickly. Reboot sorts it out until it happens next time. Finding and uninstalling the rogue app sorts the issue, but it's a bit pain. Task killers don't help even a tiny bit, since they can't restart system service, and it's not the app that's running the loop.

Actually, for me, only clearing dalvik cache sorted it out. I had my battery die, swapped in a spare, and that one died within an hour or two....soooo yeah, reboot def did not fix the problem! xD

Use WiFi whenever you can. WiFi will more than double your cc very life over using 3g. Even just sitting there idle, its a huge difference.

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?

[Q] "Android OS" Taking Up My Battery

I have used the Droid, Ally, Galaxy S, Galaxy Tab 10.1, Droid X and many other Android devices without this problem. This phone is different. Android OS has been taking up 25-30% of my batter with everything I do. Complete restore, update, custom roms, etc, nothing works. I averaged on my other devices well under 10% of my battery being used for Android OS, but this one uses a crazy insane amount and my battery is dead in 7 hours on 3g only mode! What's the deal?

That is a lot. The most i have seen is like 10%.

I only have 4.5 hours of uptime right now, but mine shows 4%.

4% here.
You have something installed that's using the "os", or some app that relies on a service that is now gone.

if Android OS is that high then you're basically doing nothing with your phone.
Try watching a NetFlix video for an hour, or else playing a game, etc.
You have to realize that your phone never actually turns off (else you'd never receive phone calls ) so that the OS has to be running.
If you're doing nothing, just letting the phone sit there idle, then of the 5% of the battery that you let it take up while you were waiting to see if it went down, 30% of it was consumed by the Android OS. It makes sense if nothing is being used that hte OS itself will be the largest user of battery, b/c, as I mentioned, the OS is still running, even if in sleep mode.
And, TBH, it actually made more sense that the old way of reporting Cell Standby was taking up 'so much' battery - b/c if the phone is idle, then I expect that the phone call monitoring aspects of the OS would take the greatest amount of battery, b/c nothing else is using the battery.
You have to take what you see in battery usage with a grain of salt. If you're not using your phone and you see a 3rd party app taking up 40% then you have something to worry about. If the OS itself is taking up that sort of percentage, it means nothing else was running ot take up the battery.

I agree with John that non-use will cause OS to seem abnormally high.
However, your 7 hours of battery life is terrible:
If you are having short battery life here’s a list of things that can help. Just read through the list and select the items that fit with the way you want to use your phone. Not all items will work for everyone and this list was written for the Droid Bionic but should work for your phone too:

This is a link to some very good videos about saving battery power on the Bionic (there are 4 parts and the other parts will show up as available videos when part 1 finishes):
Battery Saving Video
Part 1: http://www.youtube.com/watch?feature=player_embedded&v=cvWg7SbUgsI
If battery life is still bad: Consider doing a factory reset: These have gotten pretty painless lately by following these simple steps: 1. Make sure Backup and Restore are checked in the Privacy setting. 2. When going through the setup after the reset, turn on wifi as soon as you can (assuming it is available). 3. After you have entered your Gmail account info, you will be presented with a screen that has two check boxes. Basically they are "Do you want Google to backup and restore this phone”. Make sure you check both of those. Your apps will then automatically reinstall (paid and free). Set the phone aside for a minute or two and let the apps download and install. 3. If rooted, use an app such as titanium backup to restore data only to select apps such as Tapatalk and you will not have to re-enter all your login information. I do this for 3-4 apps (Tapatalk, SPB Shell, etc.).
I've been flashing new roms/updates about once per day lately and I can be up and running with all my apps and settings back in place in less than 20 minutes. It's pretty painless now.

When I first bought my Bionic, it was eating up battery like crazy. After 2 replacements phones, I found out that some Bionic's were having an issues with Draining battery. My 3rd Bionic is great. On my original Bionic, it would take me 2 extended batteries and still could not make it through day under moderate use. Now, 1 extended battery will last me all day with heavy use.
There are some faulty Bionic's out there. It was even mentioned on Droid-Life. I think the original one they tested had issues with battery drainning really fast.

- 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 1) new battery, 2) do a factory reset, or 3) 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 calibrate 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"
- Turn on Bluetooth only when you are going to use it.
- 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’ve finished using the phone.
- Turn off in-pocket detection. In-Pocket Detection has been the source of many issues already.
- Keyboard: turn off vibrate on key press and sounds for any keyboards you use
- Use a red or black screen background. On the original Droid screen--not sure about this Bionic screen--red was the most efficient color that could be displayed.
- 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. Put the phone on charger when you go to bed every night.
- Consider install the Home Replacement app Zeam. It is basic app that uses very few resources and will help with battery power.
- 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.
- If you are using Live Wall Papers, stop!

If battery life is still bad: Consider doing a factory reset: These have gotten pretty painless lately by following these simple steps: 1. Make sure Backup and Restore are checked in the Privacy setting. 2. When going through the setup after the reset, turn on wifi as soon as you can (assuming it is available). 3. After you have entered your Gmail account info, you will be presented with a screen that has two check boxes. Basically they are "Do you want Google to backup and restore this phone”. Make sure you check both of those. Your apps will then automatically reinstall (paid and free). Set the phone aside for a minute or two and let the apps download and install. 3. If rooted, use an app such as titanium backup to restore data only to select apps such as Tapatalk and you will not have to re-enter all your login information. I do this for 3-4 apps (Tapatalk, SPB Shell, etc.).
I've been flashing new roms/updates about once per day lately and I can be up and running with all my apps and settings back in place in less than 20 minutes. It's pretty painless now.

When I first bought my Bionic, it was eating up battery like crazy. After 2 replacements phones, I found out that some Bionic's were having an issues with Draining battery. My 3rd Bionic is great. On my original Bionic, it would take me 2 extended batteries and still could not make it through day under moderate use. Now, 1 extended battery will last me all day with heavy use.
There are some faulty Bionic's out there. It was even mentioned on Droid-Life. I think the original one they tested had issues with battery draining really fast.

That is weird. I wonder....could it be due to actual batteries as opposed to the phones?
But in the OP's case, I doubt it - it would be too coincidental that his battery were to fail right as he applied the update.
@OP - you might also try conditioning the battery, fully charging and then running it down a couple of times and seeing if it stabilizes. It might have to do with the update wiping the stored battery stats (long shot, I know, but still)?

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

'How To Get Better Battery Life' tips and tricks

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

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

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

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

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

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

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

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

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

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

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

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

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

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