ROM: CM9 latest nightly
Kernel: CM9's own
Radio: T-Mobile's UVLC8 (yes, I'm on T-Mobile)
Brightness: Auto (shown in screenshot)
Synced Gmail accounts: 3
Accounts in Email app: 0
My battery drops 20% in 42 minutes, which means it will be depleted in 3.5 hours. And this is mostly due to the screen. Why? I use the phone moderately and ALWAYS press the Power button to turn the screen off whenever I'm done replying to a text or doing anything with it.
Any suggestions?
Well judging from your notification bar you have bluetooth, WiFi, fb sync all on and you aren't even connected to a WiFi network or Bluetooth device. Try turning those off when they are not needed. Also go into the Facebook app and go to settings and change you sync time to a little longer than an hour (if you can stand it). Try that for now and see what happens

Some info on screen on time would help, 3.5hrs screen on time is barely below average. I would expect that if FB is always syncing and blue tooth.
Also I would verify you don't have a wake lock going from charging. You can check with CPU Spy, better battery stats, as well as some others. Cpu spy is likely the easiest way.

Every once in a while I'll get a flash that does this, the battery just seems to be losing its will to live. I don't understand it myself but I restore my last nandroid backup, and then flash again. After that all goes back to normal.

I always keep WiFi and Bluetooth on. I thought neither one of those really used a lot of power unless actually connected. I use BT only in my car and WiFi only at home (evenings). My FB refresh interval is set to 1h. I hardly think this is draining my battery.

Better Battery Stats wasn't free, so I installed CPU Spy and Battery Spy, I am letting the phone charge to 100% and then, I'm going to unplug it and report after about 30 minutes.

Might want to think of picking up some NFC tags and setting profiles so stuff like Bluetooth will automatically turn on when in your car, and off when you leave. And BT and Wifi do drain power when not connected because they are searching for connections.

But wouldn't WiFi and Bluetooth show in the battery usage screen with a high percentage? They would show by themselves or under radio and those aren't high at all. It's all on the screen. That's the problem, it seems. And what I explained earlier is that I don't use it much. I will get a text message, I'll reply and automatically turn the screen off before I set the phone down. I never forget this. I'm actually anal about it. LOL
I just installed Better Battery Stats (thanks for the tip!!!) and will test with all 3 apps as soon as I unplug my phone to go to lunch. I haven't been able to do this yet. Crazy day here at work.
Thanks again.

Flash Instigators Kernel with Smartass/Badass scripts (not a joke....)
It will help you tremendously. You must reflash with every nightly update you do.
Sent from my SAMSUNG-SGH-I727 using xda app-developers app
OK, so 4.5 hours and battery discharged 38%. I guess that's not terrible, but my screen was only on for 26 minutes of that time and the phone is reporting 55% of the battery drain came from screen use. I feel battery life could be a lot better just because of this.
What else do these screenshots tell you guys?
I noticed KIK Messenger and MailDroid there. They both sync a lot. I do have a couple of IMAP accounts on MailDroid that I forgot to mention in my OP. But, still, I go back to the fact that most of the drain comes from the screen. These aren't related.

Oh, true!!! I flashed InstigatorX's kernel when I first started flashing the nightlies, but, since I flash them every 2-3 days, I completely forgot to reflash the kernel. OK, it's more like I didn't know it was getting overwritten and I had to reflash it. Thanks for the reminder!!! By the way, do you go with stable (4.0b) or the latest experimental (5.3.2)? Also, do you just flash the kernel? What are those scripts and what do you do with them? I did not understand his instructions. Maybe I should be asking there, but since I already have you here...

For one, turn your screen brightness down. I use auto-brightness and never have a problem seeing it, and my battery drain is ok that way.
Two, you've got the AudioOut_1 wakelock. Turn off system sounds in the settings menu (keytones, touch sound, screen lock sound, vibrate on screen tap) and that will take care of that.
Any type of instant messenger service (Skype is well-known for doing this) will wakelock your phone while it searches for IMs. No way around it other than an uninstall. You can't control IMAP pushing, but you can control folder polling, which eats up a lot of battery. I'd set your MailDroid accounts to not poll folders automatically more than once a day.
And definitely turn Bluetooth off when you're not actively connected to something. You might as well be using your phone as a flashlight with how much power BT burns through.
I am currently on RC2. I went to the 21/22 nightly but was not liking how it was behaving so I went with the RC for now.
In INSTIGATORS forum you will see in the links to the kernel one that says <-------- works with RC2.
I used that one and I am happy. Sure you could do the newer ones but I am happy where I am at currently.
Just boot into recovery and install from zip.
(Assume u download the zip on your phone....)
Its easy as pie!
You can play with the settings if you want but the default settings work pretty freaking good!
I would for sure recommend going to that forum as Instigator himself can answer ALL your questions in depth.... I am merely a messenger and user of his kernel.... wish they would just merge it into the cm9....

Screen brightness: I use auto as well. It's in one of my first screenshots in this thread.
AudioOut_1 wakelock: Done. Thanks. I'm going to miss the touch and screen lock sounds. LOL I left dial pad touch tones and volume rocker music controls in that same secton checked, by the way.
MailDroid: I went through all the settings, both general and for the e-mail accounts and couldn't find a place to specify folder polling interval. Do you have it installed? If so, could you tell me exactly where to find this please?
Bluetooth: I'll try my best to turn it on only when I needed. I could also follow dakpluto's suggestion with the NFC tags. But then, I'd have to leave NFC on. Doesn't that drain battery too?
And you see, although all of these will help, don't you agree based on my screenshots that the biggest offender here is the screen and this is the area I should really be looking at?

Here's what I just did:
1) Installed latest (7/23) CM9 nightly.
2) Installed InstigatorX's 5.3.2 experimental kernel using CWM.
3) Installed InstigatorX's BadAss script using CWM on top of the kernel (I guess that's how you do it).
I will see how my battery behaves. It'll be difficult to know which of the many things I did is the one that yielded the biggest improvement, however. Oh well.
Thank you all!

Yep I have power saving stuff such as turn off wifi when idle, I dont have GPS on 24/7 and I dont have wakelocks, I also set mine to use 3G/4G rather than LTE. If it was a solid blue that means something will be constantly on draining the battery.

For performance I prefer smartassv2 for power saving I would go for badass governor. With badass it doesn't jump clocks to max but goes by phases thus not aggressive and doesn't eat a lot. Test them out read the change log to see if changes pertain to you :good:

Well guys,
It's been a long time since I realized my Nexus ONE was draining a lot of battery.
After some testing I figured out one of the most probable causes for that, Autosync.
So I started creating a proof of concept app in order to run autosync at a specified custom time.
On the other hand, I read some users in this forum talk about the possibility to monitor Signal Strength and disable APN if under a given threshold... so I did it (and added Autosync control on low signal too).
It is very useful when you work all day in low signal areas (as me).
Remember.. this is just a proof of concept... may fail a lot or never!
Search for it in the market!
Enjoy
IMPORTANT: Dont kill the app! Exclude it from memory savers (automatic tasks killer). And dont worry about memory or CPU use, it is negligible.
Update 23/08/2010
New Version 0.2. Hope you like it
You have to unistall the previous one (if not it won't install) because I lost my previous certificate . Sorry!!!
Go to:
https://sites.google.com/site/shutupbatterysaver/
Interesting...will be testing
What a great idea!
But does this app use a lot of battery monitoring the signal strength and adjusting for this?
will this work on other phones too or just nexus at this time?
First testing i was able to change settings but it seems to fc on me. Using htc hero cdma on darchdroid.

It works perfectly on HTC Hero GSM in Spain with the android 2.1.
So I don't know... I don't have an American Hero.

Dont worry for CPU(battery) drain.
When using Scheduled Autosync it just uses a few miliseconds of CPU for each Loop.
And for the Signal Strength monitoring, it checks it every 10 minutes and only uses (again) a few miliseconds.
If you have Spare Parts, you can check it yourself!
Wow! I instantly noticed a difference in drain even when monitoring it with adb. I'm impressed. What are you guys settings looking like? I am not sure how I should set it up. If I set the sync on for every 25 minutes, does that mean my phone will ONLY auto sync every 25 minutes? This app is long overdue! Thanks!
on my nexus if I leave the app and click on it again on the drawer, the app resets everything (settings, logs)

Yeah, would love to hear some other users' settings that are working for them.
Like maybe the cutoff for the signal strength level.
also, am I suppose to leave sync off?
congratulations for your job. anyway i have an issue with my nexus one. the app semms to work for about 5sec then all the settings are reseting and apn and sync are switching on even if my signal is below my previous settings. do you have any idea?

Why are you reseting the app?
I mean, the app is meant to be always alive.
You should never kill it and exclude it from any memory saver task killer that you have. Otherwise it cannot work!!
Dont worry about leaving it alive as it only uses a very very small time of CPU.
Sooo... Dont Kill it!!
Just let me know your results
I am currently using:
- Autosync due to Timer 1h - 3m
- APN off if Signal less than -90dBm
It works nice!

I just got my Nexus S on April 12th, don't have many applications installed. My battery only lasts about 10 to 12 hours and I haven't been able to figure out why. I've noticed other people have much longer battery life than this. I have 3G and mobile data disabled and use only WiFi and that too only when I'm home. From the "About > Battery use" place I discovered that Display uses around 50%. I had my brightness settings set to auto always. Today I fully charged it and after an hour or so it was on 83%! I didn't even touch it. It sucks to have an awesome phone and to not be able to use its features because of fast battery drain! please help.
Check email sync ...
Check always sync ...
Check weather sync ...
Check facebook sync ...
Check all syncs
Mine can last up to 2 days
But I don't sync like crazy ...

Agreed with ScooterG. Pretty much johnz had a thing against me because of a previous battery thread yesterday.

I unplugged around 8am and now its 12am here and the phone is down to 86%. only 4 hours later. And I didnt use much during those 4 hours.

Well 86% after 4 hours is a great battery life! 96-86=10% It gives you (4/0.1) a theoretical battery life of 40 hours !!!
On the battery manager click on the graph to see what causes your battery life to decrease very fast: GPS, Wifi, Awake or Screen on.
I also noticed the battery meter app used quite a bit of energy you should remove it, remove also the task killer it may drain you battery as well.
I'm trying out the suggestions in this thread right now. They seem reasonable. It might be useful for you.

Yes! Thats great battery life! You see, after I made my first post I read somewhere that you should drain the battery completely and then do a full charge. So I kept on playing with it until the phone shut down and then plugged it in before I went to bed. I made the second post after I woke up and didn't realize that at that time the battery life has increased. I havent charged since that post and been using it, the battery is now at exactly 30%. Been running for 17 hours and 45 minutes.
I guess my problem is solved
i lose around 40 precent overnight everyday
its really frustrating knowing that i have to work with it full day afterwards
so is there any fix for this?
No idea what youre talking about. Mine only drains 20% with wifi and wifi apps running overnight.
Maybe you should look over what you got running, and if you got a custom kernel, reduce the lowest frequency of the cpu. Im running mine at 450Mhz or something.
Ooooor maybe 'overnight' for you is like 26h ?
You could also............

First thing, you should get CPU Spy from the market. This will tell you if your TF is going into deep sleep or not.
If you were experiencing the same issue under HC then ICS most likely wouldn't fix the issue anyhow.
Prior to ICS I was loosing about 25% over night which just shouldn't happen. I was rooted but stock otherwise. I unrooted my TF & completely wiped before flashing ICS. One cool thing about ICS is there is an intergrated task manager widget. You can see what programs are running at any current time. There were three programs that were constantly running that I disabled. Those were PixWE, Netflicks, & My Uploads. Netflicks kept wanting me to update but I don't use it so why update it? I simply disabled it and there are a whole host of other programs that can be disabled too.
With all this being said I am only loosing 3-4 percent over night running ICS completely stock.
Try airplane mode
There's an app in the market that simulates airplane mode, but allows wifi still. After I installed it I stopped losing battery overnight. It's basically a wake-lock issue.

+1 This worked for me too but for a different reason. My TF tends to leave wifi switched on, even when told to turn off when the screen does. It could also be a rogue app as described above. Once you sort it out, overnight drain should only be a few percent at the most.

There's an app in the market that simulates airplane mode, but allows wifi still. After I installed it I stopped losing battery overnight. It's basically a wake-lock issue.

How to diagnose here
I lose ~20% overnight in flight mode.
If I go Settings > Battery I see it's a lot of Android OS. But widgets must be included in that. So then I go settings > apps > running and see a few apps running, but I can't tell which of these is killing the battery and I don't know which app would tell me ((can I run top on the the commandline?)). I will experiment more and report back. I suggest you do that same.
This should go in the first post of this thread:
To diagnose this charge before sleep, put into flight mode overnight and look in the morning to see if the Android OS has been the culprit.
Perhaps you don't need any 3rd party apps for diagnose but if you need to be available for early morning calls use a profile scheduler.
Get a new Kernel
The main problem is the kernel in ICS, a way to fix this is changing your kernel, I do recomend the Test kernel from Guevor, install from version 11 to up, test it and keep the one you like. My tf is lasting fully with keyboard, around 30hrs.
I use test 13
but on .17 and not .23
I'm on ICS 4.0.3 with 3.0.8-NEO though

My Nook got stolen and I'm waiting for a DroidPro to arrive so this would be on my main phone. When I've tried to flash just the kernel on it's own I've had problems before. This time I'll give it a go but am I missing something in terms of flashing a new kernel on?
I'm on ICS 4.0.3 with 3.0.8-NEO-3.0-TeamICSSGS-257174-g197c9a1-dirty (build *07)
Other than the possible battery problem it's been good. I just want to check to see if yo uhave anything more concrete to backup your decision... that a different kernel really might make any difference because that Test kernel from Guevor is very much in flux... I'd no idea which one to choose.Up to test15 now.
(thread for reference here: http://forum.xda-developers.com/showthread.php?t=1565519 )
For convienience it would be nice to backup the current kernel first as other than battery it's working well...
update, edit instead of bump:
ok, I lost 1% an hour last night in flight mode (6% over 5 hours) with all background apps and services killed. Does that seem about right? The interesting thing was that not all processes/services/backgrounded showed the same on different task killers...
I bet there's lots of people updating kernels when actually it's an app, or the left over effects of an app or something like that.

Use Auto Airplane Mode by DON this fixed my problem with battery drain from the wifi staying on.After 4 days of use I still hade 35% battery left!
I've used the N5 for a few days now and I must say I'm impressed with everything except for the battery.
So the thing is, i really gave no craps about the battery on my Defy because I didn't care much for the phone either; so I'm sort of confused and out of ideas for battery saving.
I haven't rooted yet, but when I do my best guess would be just to down-clock the CPU, but how well does that really work? I use No-Frills and it works about 93% of the time, other times it just reverts. Do I need a kernel?
I keep it on about 10% brightness because I like soft lighting and screens. That works to a certain extent as well as the fact that I'm not a data user and I always turn wifi off when I'm not using it (like, immediately I will go and toggle it).
Other than turning off sync, is there anything else I'm missing? A good app maybe?

Few things i've done is turn off wifi always scanning. set location to device only. undervolt -75 and max cpu 1575. i'm using cataclysm rom and frank r16 which was just recently released. when i was on r14 kernel i was getting about 7hour 1% drain on idle connected to wifi. I also try to monitor what I want to have push notifications for. So check what you have constantly Syncing.

Biggest changes for me were:
-Disable Hotword detection. Turn it back on when you want to impress friends and otherwise hit the mic button manually. Increases Screen on Time.
-Disable Auto sync. Set an automation to only sync while charging instead. Increases Battery at all times, may slow charging a tad.
-Disable Locations. Enable if needed on the go. Can't automate this with Llama but I'm guessing it would work using Tasker. Many less wake locks you can go hours without a single one now.
Hi, I'm worried about my bad battery life. Any ideas what it causes or how to improve?
I'm on latest Carbon Rom (Android 4.4.2), Now activated, Hotword detection off.

I don't get it. You have 1 day 9 hour usage and 1 hour 42 screen time. Your screen time is low but your usage is quite a while, better than mine. Could be bad signal, you have 1 bar in all the screenshots posted. Try turning off sync or mobile data when not in use.
It's a combination of poor signal and gps settings.
Switch location mode to Device only and get us an overnight BBS log.
System UI is unusually high. I can only assume this is customized UI elements draining the battery. Google services are 2nd on your list so locations and auto syncs, among other things.
When you're getting normal battery life Screen should be at the top. Anything draining more than Screen you need to look into.

Actually, he charged the phone (look at the first picture above the number 26 ) and as result, it was less than 1 day, 9h.

Thanks for the quick answer. I switched to 'device only'. Please find attached the overnight BBS log.
any ideas? someone?
Hi,
I see systemui is at the top of the list in all your screens. Are you using "pocket mode" or lockscreen notifications? I had the same issue on Mahdi rom and it went away when i disabled "pocket mode"
Are you running a custom kernel?
Some general battery saving tips are :
-Lower your brightness (i have mine set at 20%)
-Download "Wakelock Detector" and "Greenify" from playstore. These 2 apps will solve any wakelock problems.
-Turn Google Location Reporting and Location History off.
Sometimes a simple reboot does wonder for your phone.
Everybody has their own best combo of ROM + kernel so it will be up to you to find what works for you.
I'm currently running Mahdi's ROM + Elementalx and get 4 hours of screen time, 4 hours of music playback (from SD card) and 20+ hours of standby time

Hi, yes I'm using pocket mode. Too bad that it's drains this much battery! I love this feature
to me it looks as you having terrible wifi. and since you left the wifi on, your terrible signal drained the battery.

Try turning off the feature for a day and see if it improves your battery life any.
I'm also a big fan of the pocket mode feature and s2w/dt2w features because i hate reaching for the power button but it killed my battery.
What i can suggest to you is to try an app called Gravity Screen by one of our very own xda developer. Somehow, he managed to get the turn screen on/off via proximity sensor to barely drain any battery. I use this app combined with Dynamic Notifications and every time i take my phone out of my pocket, i get notifications like the Moto X and screen on without power button.
Best of luck!
flash back to stock & change tamper flag, and get an exchange. I found out that the earlier models have some with batt and radio problems

Confirmed. Pocket Mode killed my battery, too. Since I deactivated it, my battery life is acceptable.
