Battery Problem [CM7]

Hi everybody!
So I am using CyanogenMod 7 Beta5.1 And I'm having huge battery problems...
It's draining abnormally fast (30% lost during night).
It started to happen when I got problems with my Defy and flashed 3.4.3-11
And now updated to 3.4.2-117.
Before these problems it usually drains only 3% during night!!
Also everytime I boot my phone, when it's completely booted I hear the camera sound (when you open camera app,it makes a physical sound).. It never happened before...
I overclocked my phone to 1100Mhz but I don't think it really affects the battery (when screen off it's set to 500Mhz)
Please help me!....

I was having that problem and I turned fast boot off and it solved the problem for me. The phone doesn't really shut down all the way if fast boot is on.

um... a new thread? really?
by the way, i have this problem too since beta 1.. i don't know why..
but i still like it because CM7 is so fast without OC.
i try to compare froyo and CM7, with same apps and same apps settings,
CM7 lost the battery faster than froyo, even when in flight mode.
the strange one is, even the memory usage is so low on CM7 (no motoblur crap),
but why battery still drains so fast..
in battery usage statistics,
on CM7, it shows that "Display" is the one who responsible drinking so much juice (60% and the other is just 3-10%).
on froyo, is not the "Display" which responsible drinking most of the juice, it is "Cell Standby".
i thought gingerbread should have good battery management, and the battery should last much longer than froyo.
i'm sure it is a bug on CM7 for Defy.
but whatever, at least we have a Gingerbread on Defy from a great dev like Quarx.
while motorola working so slow on releasing froyo with its motoblur crap.

Hi guys,
I'm having this issue too, and i note since a few days ago. I don't know why, but my Defy is sucking his battery too fast. Could it be a bug ?

it's a little bit difficult to follow the bugs and the solutions in a huge thread like the other one. so i think that this that could be a mayor problem for all of us should be treated in a differente thread.
I use Motocharge since 1 day to follow how it discharge during the day.
I say it in the other thread, the phone loose a lot of battery when i don't touch it. sometimes it loose like 5% in 15mins and i don't touch it. maybe it doesnt sleep well, i don't know..
I hope that Quarx can solve this, because in the other betas of him i don't have the problem. only in the 5.1.

battery draining
I think It´s a bug, because I used before BETA 5.0 and without any battery life was almost 3 days in normal use, bur now with BETA 5.1 only two days or less.
By the way I´d proved with 3 or 4 diferent roms, but the same result.
But I´m sure Quarx will deleted this bug in the next version

same problem for me,but b3 and b4 is ok

apart from low battery life.....i noticed substantial increase in battery temp..normally its 32-34 deg cel.....but wid CM7 it raises to 42-45 deg cel.....waiting for a solution so that i can come back to CM7...

I use Toggle 2G/3G to switch to 2G when phone goes to sleep. I set wifi to never sleep and use it as much as possible over 3G. I also set brightness levels long time on 16 so that in the shadow I always use just a little energy. This way I almost get double battery live.
+ it's better for battery to charge every night, empty or not, and let it go lower just occasionally.

yes, this issue is really annoying, 30% battery drain overnight.
something is definitely running unreasonably... hope find it.

I think it depends upon what "type" of defy u have. My battery that only used to last for 12-14 hours in eclair now went for 2 days last 2 charges.
Also depends upon how many widgets and apps u running... hard with mobile phones to judge battery as so many independent variables.

OK Guys, this is an old thread, but I think it should be deleted or at least people should read this before registering this thread in their mind:
The battery drain 'issues' were almost always due to two things:
1- For the beta 6 version or older of CM7- there was a bug with the auto-brightness which was heavily stressing the cpu and making the system lag badly - hence: the battery drain. To fix this: you have to stay on auto-brigthness. So just make sure that the auto-brightness box is checked and ON. Additional info: some users also complained about the 4 action buttons (menu, home, back and search) not lighting up ---> fix: un-check auto-brightness and re-select it: done!
2- Users did not set their Network baseband properly. Fix: use the Defy Baseband Switcher application and select the newtwork that applies to you. If you don't do this, your phone might have signal reception (phone and sms) but it will use more power to communicate and get a proper lock to your phone service provider.
I don't know what is the exact build # that brought the Defy Baseband Switcher (as far as I can remember, CM7 beta 4.1 had it) but all the 'newest' CM7 will have it anyway.
And if you want to further decrease your battery consumption, you can still do it like this:
- use the bootloader cpu settings: OC'ing and governernor type to change the cpu speed. [From CM7 default 1000MHz to the Defy's stock 800MHz] and change the governor type from "interactice" default to "on demand" [OK: I'm not sure about governor change will improve or not but that is the Froyo's default I believe].
- install SetVsel to underclock --> by lowering cpu Vsel upon the 3 cpu frequencies. Do some reading; you might need to uncheck its "[email protected]" option AND also have Milestone Overclock installed for it to work properly.
- USE a recent nightly (post May 29th: there was a possible problem with custom recovery backup restoring prior to that) and you will be able to set your screen display brightness as low as you want [fix the bug described in point 1- above].
- use DroidWall and/or the CM7 built-in applications' permissions control to block some apps' access to internet and networks. BE WARNED though: changing permissions CAN make an application stop working or create problems - don't submit bug reports if you do that.
- Avoid high usage of apps that drain battery quickly (TuneIn radio is power-thirsty one that comes to my mind...) and apps that have to create catalogs and thumbnails (ex: Photoshop, Titanium Backup, Gallery, ...)
- If possible: use 2G network only, disable data synch, auto updates of apps and social networks.
- set your WiFi sleep policy to "Never" [while in Wi-Fi settings, press menu button/ Advanced] and avoid frequent Wi-Fi ON/OFF switching.
- Lower your display brightness and switch that screen off at any chance you got!
There are many other ways I'm sure, but those are the main ones anyway...
I've seen high temps yesterday on my Defy, but I later realized that I forgot to re-set my Baseband after a CM7 nightly install... It 'could' also happen when a (background) service goes "beserk" and overload the cpu: absolutely not necessarily related to CM7 --> faulty apps and bugs happen... Just stop and clear the cache of that app and/or reboot your phone and problem should be gone.
CM7 is now really stable; a VERY FEW little hickups remaining still (like with the camera, but negligeable), but the large amount of new user controls that it brings clearly overcomes the 1 or 2 minor bugs left --> IMO, just having control over each and every applications' permissions justifies forgetting about using Eclair and Froyo. Problems in CM7 are being actively sorted out and new user controls and other useful options are added in almost daily manner through the nightly builds.
I'm categoric: on CM7, I now have more control over where my battery juice goes that I've ever had on Froyo....
So please stop alarming people with high battery usage drainage on CM7 and give it a try by following the right proper steps; I'm sure that you won't regret it.

Display instead of cell standby showing up first in battery consumption means that Froyo (or CM7) uses less battery. The display just stayed the same of course, unless it's tuned brighter, the percentage increased because it's a relative measurement.

Is there any solution to the battery drain on ics

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.

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!

[Q] What is considered normal screen battery percentage for 7.7?

My screen battery percentage is around 70%. I am wondering if that is normal because on a screenshot I saw in another thread, the person's screen % was in the 40s. If it isn't normal, can someone help me with bring the the battery usage of the screen down? (My battery is being drained and I was wondering if it was the issue with the screen .) And sorry if I seem very noobie >_<.

The higher your screen percentage the better it is because it tells nothing else is draining your battery significantly. At 40%, there are other things that are running your battery dry aside from screen.
You could post a screen shot for others to see and advice.

If you're rooted you can always clear battery stats in CWM. Some devices appear to perform better. Also check what's running in the background (processes). Disabling things like GPS can save battery. If you use TiBu, freezing unneeded apps can free up power and resources. If you venture into that, I would suggest doing one at a time to avoid freezing apps that your tab needs running. Google/search forum as I'm sure others have posted their experiences.
Just a few random thoughts....

I notice android media process consume your android battery. I am also wondering about android media and server process in my GT- 6800 with paranoid 2.55. Here are the process that help me out
try to delete all you music or picture files and back it up to you pc
unistall the game and try to install game one by one to see which game will consume your android media process
using terminal emulator to disable android process media. I refer to this site; http://code.google.com/p/android/issues/detail?id=37199
1) have Android SDK installed on your laptop
2) enable debugging on your *rooted* device
3) connect it to you laptop via USB
4) adb shell
5) su
6) pm disable com.android.providers.media/com.android.providers.media.MediaScannerReceiver
It works for me and now I have no media process in system and media server consume reasonable memory. Thanks

My tablet is rooted, but I don't know how to clear battery stats. However, I am currently using Battery Monitor Widget Pro and I see the calibration tab. Once again, I have no idea how to use the calibration thing on this app. And I disable GPS all the time, unless I really need to use it, which is hardly ever. As for TiBu, I don't know what that is. Is that Titanium Backup?

If you have CWM installed then there is an option (from the menu) to clear your battery stats. If you don't have CWM then please download from the "development" section.

Poke around in CWM. I believe it's under Advanced. And yes, TiBu is Titanium Backup.

Excessive Battery Drain on Airplane Mode

My Infuse 4G is always on Airplane Mode with Wifi turned on. I use it as a secondary device and like an iPod Touch/Media Player. However, even if Airplane Mode is on, the number one drainer of battery is Cell Standby at like 60-70%. Also, the phone never enters deep sleep and Android OS constantly keeps the device awake. As a result, from a 100%, the phone is dead within 8 hours. There has got to be some sort of fix for this. I'm running the latest Beanstalk 4.4.285.
P.S. I have entered AppOpps and denied the permissions to wake up and stay awake to the following apps: Google Search, Google Play Services and Android System.

Try rebooting. A custom launcher may be a culprit! Apex Nova Go are reliable! Do a clean flash again!
There must be an app which is running in background! Try deleting a recently installed app, try clearing cache of google+. Try uninstalling anti viruses which are useless in a phone. Install an app called Greenify in Play Store. Greenify most of your installed apps with it. It really boost battery life.
Change governor in performance to either Interactive or OnDemand.

And if you want, go into phone info (by dialing *#*#4636*#*#) scroll down to the button that says turn radio off, and that keeps the cell radio off.

Some apps are not properly closed out when you exited it. I had to force close some of them. Not sure if this is happening with other people. Go into: Settings > Applications > Manage applications or Running services open apps that you recently open/closed. If Force stop light up it mean the app still running. I'm aware that some apps remain running due to user setup for it to check for update. The app I'm referring to shouldn't since update is turned off or in manual update mode.

I have pretty much run out of options. I have no idea why my battery drains even in airplane mode. Supposedly it is because of "cell standby".
EDIT: If I can solve this issue, I can put my Infuse to good use again. Unfortunately, I can't use a phone for anything if its battery dies in 8 hours while idling in airplane mode.

Same here~ i just bought an 3.7V 3500mAh Li-ion extended battery off of amazon for under $10 and since the original is 1750 mAh battery im hoping it is going to do some noticable good. Nonetheless, the problem still remains so please if you (or anyone) should discover any breakthroughs than SHARE with us too... please! Thank you kindly <3

Try rebooting, it will help. Try force stop and disable the both "Google Search" apps in app manager (first maybe called "Google App" if you updated it). Guys please keep me updated with this because I'm so confused. It is so stupid and without any kind of tiny logic for the battery drain on AIRPLANE mode that turns off all radios and waves............

Need help on battery life and CPU usage

I have a Samsung Galaxy S7 and the battery was doing fine. A few weeks ago the phone started getting quite slow and the battery life went way down. I had installed a few apps around then, so I removed them and still battery life was bad. I tried restarting the phone and that didn't help. At the time I was running Marshmellow and I was using OSMonitor to watch the system. I was finding that Android OS was taking most of my battery and 30% of the CPU all of the time. Not long after that Nougat became available and I upgraded thinking that might help. It didn't help and OSMonitor no longer worked. I switched to GSam Battery Monitor and used adb to give it the permissions to see all app information. I'm still finding that the Kernel is taking 28% of my battery and Android System is taking 37% of my battery and I can't figure out why. I would rather not need to do a full reset and install all of my apps and settings again, so I'm asking if anyone out there has ideas on things to try and fix this. This is a non-rooted phone running the stock image from Samsung/Verizon.
Thanks for any help.

try activate the Battery Saving option and use it for a day and see if helps

I've had this happen to me before. The phone was getting seriously hot while it was happening too. I decided to do all I can without doing a factory reset (I was on vacation at the time, so no access to something to backup my data).
I cleared the cache of all apps. Then I disabled all of the stock apps I didn't need (like Gear VR). I also shuttered apps running in the background to about a max of 3 apps open at any given time. That stopped the insane heat issue, but Android System was still sucking 30% of the battery. I turned off Always On Display, that got me down to about 25%. A factory reset got the phone down to around 10%, and I never saw the issue again.
Before you do that I would recommend checking out this thread below as there does appear to be a bunch of other possible solutions provided by others.

Try this , it helped me a lot .
Download from the XDA forums the Kernel named : "Apollo Kernel" v7
Just flash it , and when you install it , if you dont use your phone for high end games or hard work,that requires high end specs , then you can underclock the cpu/gpu .
It s a battery life saver, plus , your components will be much better in terms of thermals/life
