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!

Why is my battery life so bad?

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.

that's covered under android system I believe. Most important, it causes wake locks that keeps your phone from deep sleeping.

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!

I'm testing aokp w/ stock kernel ondemand 192/1512 and it actually is working decently for me so far. Streamed like 1 1/2 hr of video last night and 2hr of Pandora today at the gym. :good:

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:

Ways to save battery

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.

(8hours) Maximum Battery with NoteIII(Exynos) with Dr.Ketan,Pekaka Kernel and SetCPU.

This is the complete guide for the maximum battery even with power usages.
First of all i am really sorry for my bad English
ROM
Dr. Ketan ROM l21 http://forum.xda-developers.com/showthread.php?t=2519897
Applications
TW Launcher frozen with titanium backup both TW Home and TW easy mode.
Using Nova Laucher as my primary laucher.''
Usning SnapLock instead of Built in Lockscreen. (set Built in Locksreen to none from the setting).
Uninstall the useless or bloatware apps like group play, google now, g+ samsung store etc.
Greenify
Added all apps to greenify except WhatsApp, viber and Sayhi.
Setting
All air and motion functions are off.
Power saving mode on for 24 hr.
Brightness auto -5
Kernel
This is the important and main part to save more battery recently i found Pekaka kernel for my Note III. Their are many comments about drain and getting device too HOT.
So i decided to play with kernel setting. And install setcpu setting thats work for me like a charms.
So after flashing the kernel do worry about getting device too HOT even with Playing Heavy Games also i have attached the setting for the SetCpu... Match your setting below and let me know if this setting also work for you.
The first three setting are to cool down the device if the device gets to hot, it will automatically scale the processor down to allow it to cool.
The other four are to save battery while the screen is off. This will lock the CPU between these lower frequencies when the screen is off, using less mv, resulting in less battery usage.
Thanks to Dr.Ketan for such a wonderful ROM
Thanks to Pekaka for the Great Kernel for Lollipop
Thabks to the developer of SetCPU app.
Give it try and let me know by your comments if this setting work with you or not.

What version of pekaka kernel you use? Could you share screenshots of battery usage?

I can see it now. According to ur ss, usage all over wifi or 3G?

@satslu Usage over WiFi.
WiFi remain always ON in my device I'm mostly indoor user so never OFF the WiFi even not in Use.

Here. Is New Results according to which you can use Almost 8hours with screen On.
Because this result are estimated from 92% battery not from 100%.

Your screen on time is quite impressive. I was on L21 up until the last few weeks. It was much better than stock TW, but still not what I wanted. I was thinking about switching kernels, but ended up on cm12.1 and couldn't be happier. djmax81 is finishing up a kernel for it that should improve battery, and it is incredibly smooth, even compared to Dr. Ketan's rom.

@mwbuss8 can you post the screens with djmax8 kernel ?"
