Ok, Let me first say, This website and the people on it have helped me and others so many times. It's a great website with many talented people. However, I know nobody has to help anyone on here, but please listen to this and only help or post something if you have a fix or are having the same problem.
I don't want to sound rude, but I made a thread a while ago and got 9 pages of people saying that "my battery is fine" or people telling me stuff I already know, so PLEASE PLEASE PLEASE only post if you can help fix the problem or are in the same boat so we can try and get a fix.
Please don't put in the thread " My battery is fine" or "Do a hard reset" even though it seems that is the only way to fix it, I am going to reinstall all of my apps, and its most likely going to happen again.
Background information
I am rooted and running CM6, but have had this problem with the stock ROM, and many other ROMS, doing a hard reset has not helped me in the past, because after restoring my apps, and settings it seems to come back again. I am going to give you as much information as possible to help me with my battery, because I am sure I am not the only one with this problem.
My device
I am rooted and running CM6 and I absolutely love it, it is hands down the best ROM I have used, but I took my phone off the charger, send one text message, loaded up 3 web pages, and refreshed my email, and the battery percentage was down to 93% in 4 minutes of use my battery went down 7%!!!!!!!
I have had this battery drain issue with CM6, Fresh ROM, stock (rooted) rom, and Non-Rooted Stock.
Homescreen
Currently I am using LauncherPro, but ADW.launcher comes with the ROM, and I have had the same problem with that. Here is my setup to show that I am not using any data intensive widgets.
Home screen: besides all of my app icons, I am going to list all of my widgets.
1. Digital Clock Widget-It is a widget that works without an application, but their is an optional application that I don't have installed.
2. Stock android calender widget
3. Stock android 2x2 music widget
4. Beautiful widgets- silent and airplane mode toggle
5. Stock android power control

Please if anyone can help fix this I would greatly appreciate it, It may seem that the only fix is the hard reset, but their has got to be some app, or setting that is keeping my phone on or killing the battery, if anyone has found that one of these apps or settings had killed their battery, please share, and we can fix our problem.
Thanks
P.S. My battery was at 93% at the beggining of this post, and the screen was on for about 6 minutes total so I can list all of the apps and settings and its npw at 85%
install setcpu,underclock the processor, have it @ 245mhz when screen is off
make sure you are signed out of google talk and go in to settings to uncheck auto sign in since doing that its taking a load off my battery .
also underclocking when screen is off helps alot use wifi when you can or just turn off the data to save loads of battery juice
also are you running the RC1 or a nightly ?
newest nightly is doing very well on the battery hit 19 hours so far with 18% juice left
Your time without signal is 40%, so you are going to get the battery drained.
TWS is your problem and that will not change on any rom.
Now, your PRI is going to be locked in because you are rooted. So maybe a new PRI (no way to update now that you are rooted we are stuck) could possibly help with TWS.
Another thing I know I mentioned in the other post. Do a fresh install and don't install any apps. Just use the phone. If that makes a difference, than it is an app causing your problem.
Eliminate all possibilities until you have a solution.

kill the data when your in a building or areas that will make the data work harder
ALSO is any of the apps your running from a 2.1 backup ? if so that could be it too i had major battery troubles with my 2.1 back ups on 2.2
Go to running processes under settings>applications, see how many are running...if you have more than 5 running processes at a time.
.your battery will suffer. Use startup auditor to prevent apps processes not in use from starting on boot
you may want to check that your default PRL is set for cdma and not gsm.
there is a post in the dev forum about it.
you will need your MSL number, get it from sprint customer service or use cdma workshop trial. I've used both, I recommend calling sprint its fast and free.

The PRL shouldn't be an issue with the Evo. That was some type of hero 1.6 bug.
Also, I don't think the data codes work with Froyo.
You can try to download the "Network" app from the market and see if that works.
I was having a battery drain issue ever since 2.2
I think I have it fixed now though. First up. Did you wipe everything in between ROMS? I know this is redundant. But it is important, many custom ROMS have several cache, memory writing and reading tweaks applied and if the phone needs a fresh start from every angle to really utilize it all.
Honestly, the "drops to 93% without barely doing anything!!" Sounds perfect in line. As soon as the phone is done charging it will start using the battery again UNTIL it drops to 90% and then it will charge it up again. All the while saying "fully charged" I've read that on several threads. And after the initial 10% it should stabilize. If it doesn't after that, then there is a problem. You said you where 40% without signal? That seems high.
There is a thread about how these, and most other Android based phones on CDMA mobile providers have a bug that default to GSM searching, so while its looking for a signal. Its primarily looking for a GSM tower, and secondarily a CDMA. In the phone dialer, type *#*#4323#*#* (I think, please correct be someone if this isn't it) in there, scroll down and you'll see a drop down menu and it will say CDMA (auto) which is the bug. Press menu, then press "Select Radio Band" it'll FC which is normal. Noe look at the drop down menu. It will say GSM (auto). Change this back to CDMA (auto) and exit.
I know by doing this when I first got my phone that my battery life, while the phone is asleep, where way better!!
UPDATE: ignore most of that, sorry. Forgot you said you where on CM6 which is froyo, you'll need to use CDMA workshop to fix that as the code no longer works.
Hope that at least helped you out. I know the pain of fast battery drainage recently. Right now, after moderate usage and 4hrs off the charger I'm at 75%. that is with 4G on with weak signal. Some texting, and web surfing. And Taptalk this whole post. Lol.

All that previous advice about data usage, tws, or anything related to battery drain while the phone is idle with the screen off is bologna.
Lower the brightness of the screen by about one half of automatic brightness and underclock the cpu to about 245-507.
The phone will still be very usable, while the battery drain while actively using the phone should about half.

Thanks everyone so much, I will try all of these things.
By "kill the data" What do you mean?
When I was using a ROM with Sense installed their was a setting called enable always on mobile data, which basically allowed you to turn 3G and 2G off, when the phone was not on, however I can't find anything like that with this ROM.
So if you could elaborate on how to kill the data apps, that would be great, it sounds like that might be it.
And no when I first flashed CM6 it was the first 2.2 ROM, so I got all of my apps from the market, I didn't restore them from 2.1
And to the person asking if I am running the nightly or RC1, haha I don't know the difference.
I cleared all of my data, and was running a rooted stock rom, then flashed the CM6 "latest ROM" from the ROM page on 7-28, then on 8-7 their was a nightly that was 8-08 and I installed that. The mod version I have in settings is NIGHTLY-N1
http://forum.xda-developers.com/showpost.php?p=6780201&postcount=6
When I typed in *#*#4323#*#* in the dialer, after pushing the last * the (*#*#4323#*#*) that I had just put in would disappear and not take me to the menu, although I do know what your talking about. Can someone confirm if this is the correct code?
Edit, thanks to person above me
its Dial *#*#4636#*#*
when I did that and go to Phone info, and scroll down to set preferred network type it was on CDMA auto (PRL)
However under the IMEI, phone number, current network, is says network type CDMA EvDo rev. A
and 2 lines above that says GSM service: In service
Than on the bottom is says GSM Disconnects: ======DATA======
state: DcActice State connected at 3:11 AM and elapsed 14:12:24 and then is gives me an address, gateway, and DNS code.
This may sounds stupid, but should that be changed to CDMA only, maybe the PRL auto setting is still looking for a GSM network, because it says GSM: in service.
Thats proly not it, just wondering?

it sounds like these 3 don't even need to be running, I can go without the digital clock widget, who know, maybe thats trying to update or somethin, astro is a file manager, Ill switch to another file manager, and voicemail
THATS from the 2.1 ROM !! maybe thats what it is, Because even though I don't have a voicemail every hour I will get a notification saying new voicemail dial *86 and when I would do that It says virgin mobile or somethin and doesn't let me listen.
I am gonna delete astro, digital clock, and the 2.1 voicemail, and reinstall the 2.2 sprint voicemail.apk and report back.

So I just unlocked the bootloader and rooted my VZ SGN. My first root! And I have been suffering, like many, from the Android OS bug that is affecting battery life. So I was just wondering, since I now have superuser access and whatnot, what can I do to make my battery life better?
I'm still on stock ROM, 4.0.2, as of now. I will start adding ROMs later on. So for now, what can I do?
thanks in advance

This. If you're into flashing roms and kernels I'd use AOKP with Franco's kernel. It's a great combo.

I use AOKP and Apex kernel. Great match for me
thanks for all the answers. how exactly do i install a kernal? i have rom manager and all, so maybe i can use that app to do it. also, does installing a new kernal mean i have to change the ROM? and if i do install it, will all my data be safe?
and for all those who already replied with recommendations for kernals, what sort of battery life do you get with them? and how good is the signal and performance etc?
sorry for so many questions, but im new to this
Try turning off GPS or freezing maps.
Sent from my Galaxy Nexus using xda premium
I'd start by not using rom manager.
flash CWM recovery and use that to flash ROMs/Kernels. Theres a great user guide in the development forum.
This is a battery saving list that was actually written for the Bionic, but most of it will apply to the Gnex too. The main caveat is to be careful about doing a Factory Data Reset. If you do one by select it in the Backup & Reset menu in Settings it will wipe everything off of your sdcard. So be sure to backup anything you want to saved to your computer first:
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:
- 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. If you can’t do without it, lengthen it’s refresh time.
- Don't use antivirus
- Set your WIFI sleep policy to never. The default is "turn off when screen turns off". This will cause the wifi to reconnect every time you open the phone. From any Home Screen select Menu/Settings/Wireless & Networks/ and then use the Menu button to see some new options - select Advanced. Then select Wifi Sleep Policy and set it to Never. Home key to return to Home Screen.
- If you have access to wifi, leave it toggled on as it is more efficient than 3G. Wifi consumes less battery power than 3G.
- 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!

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.
thanks for all the responses. i think i might flash AOKP and franco's kernel on my SGN.
I have a couple more questions though.
1. So if i wanna flash those two, i can simply flash the rom and then flash the kernel right after, without have to re-wipe my data or anything like that?
2. does the backup feature in CWM backup app data and homescreens and all? or do i need titanium backup or something? or is it just not possible for me to do?
3. and if an update comes out for either AOKP or the kernel after i have flashed it, do i need to wipe my data again and flash the latest zip file or can i just update over the existing one?
thanks
also, do i install the kernel first or the rom?

i will install my first ever ROM shortly
I used PhoneWeaver on all my WindowsPhone devices and it was awesome. I use it on my EVO4G and it works great. I tried it on my 2nd EPIC and got the same results as the first one- horrible battery life. I went through my extended battery in about half the time.
Does anyone else have this experience? I really like the app on every other device I've tried it on. I know it's not Android because of the EVO. I know it's not the ROM, because I've tried it on stock & various rooted.
Does anyone have any tips that might make it more keep-able?
You have to make sure you're not using GPS for your locations. It eats up the battery. Use the other option of cell network (can't think of the exact wording).
Verify if PhW appears in the battery usage app list. It shouldn't.
Also activate PhoneWeaver log mode, leave it run for a day and take a look to the log to see if tere are any recurring events that shoulden't be.
As Earldom says, using alert location method and having GPS always on will make the OS to use the GPS for the location system. Ensure you have GPS off or change to Intelligent polling or AP+Cell in location method.
Finally, ensure you have the latest 2.2.8 version installed.
OK so I rooted my Note2 yesterday. Fairly straight forward and fairly quick folowing details on http://galaxynote2root.com.
Just came across it on a video on youtube and it seemed quick and easy.
Anyway It worked a treat and I have superuser rights, I installed Network spoof and wifikill and both programs run as stated.
I have just noticed that my battery seems to be on a constant drain since either (A) I done the Root (B) I installed either of the two programs.
My memory usage is also always tipping over the 1G mark.. I usually always close apps when I remember and clear the memory
I just cleared the memory and it closed 51 applications and reduced the memory to 650, And by the time I finished typing the memory usage is back up to 750 and nothing has happend! the screen had not even turned off.
Is there something happening?
Thanks
OTA Updates
Also noticed that the OTA updates doesn't work. Can updates still be applied via kies?
No pal. You won't be able to receive Kies or OTA updates. At first Kies wil download the new firmware if available but later just before flashing it will stop by saying you have modified your device or something like that. So in case of an update just download the ROM from sammobile.com or elsewhere, and flash it via Odin, pretty easy.
And I don't think rooting is hampering your battery backup, it might be those two apps, or other apps. Install BetterBatteryStats and monitor. You have NO idea how much juice could be drained by hidden ads in a free app.

I installed BetterBatteryStats and Monitor but not exactly sure what it does?
I removed the last couple of apps I installed and it seems to of slowed down the battery drain,
If you can give me a brief run down on BetterBatterStats that would be great, If not thanks again for your input.

In BBS the stats you should be looking at are Kernel Wakelocks and Partial Wakelocks, more so the latter. Set the time to Since Boot or Since Unplugged.
This tells you what is preventing the phone from going into deep sleep when screen is off.
Don't let it become an obsession like many on XDA do though :silly:
Not sure if this is a bug or something, but my Android OS usage is extremely high from 40-50%. Also the Android OS always is downloading something, my wifi icon is always downloading when on wifi, but it doesn't when I'm on a mobile network. Is anybody else having the same issues? Also my auto-sync is only for my Google account which includes Gmail, Calendar, Contacts and Google Music. See the attachments for usage statistics.
Install BetterBatteryStats (there's a free xda version available), do some reading on how to use it, and you'll find your issue easily.
Make sure all bloatware is removing from your phone, that did the trick for me.. I get 22-24 hours of usage.. on 4G of course.
I have the same problem here. Android OS uses most of the battery, whereas display only uses 20-30%, kind of weird
But the phone still gives me power for all day long
sent from my Optimus G E971
All my bloatware is removed, I got factory unlocked so I don't have the usual carrier stuff. Think I'm going to root and flash the AOSP rom onto my phone.
Its an error in reporting with ICS, it is not actually draining.
