battery?

im running the stable cm7 release and my battery life is terrible. i followed the guide on the forums here on fixing your battery life, charging to 100% pull battery put back in instal battery fix etc and overnight (short 5 hour night btw) i lost over 25% of my battery life, doing nothing ! wifi off data was on but i only recieved one or two emails all night. is this normal for cm7?
i read about how people are getting 20+ hours battery life while using their phone, if i leave my charger at home and go to work my phone is DEAD halfway through and all i use it for is the occasional phone call mabye 5-10 texts throughout the day and an email or two... how can i fix this?

I read somewhere that if you flash another ROM with battery not fully charged, it messes up calibration and you have to calibrate again. I am still with stock Blur just because I read so many issues with so many people about batteries
I hope you can get it figured out.

anybody?
is anybody else having battery life issues with cm7? if not did you do something to fix it? i have no idea what to do, the phone pretty much has to be tethered to a charger or it gets drained ridiculously fast. If i hang out with a few friends and use my phone during it i literally have to stop using it after around an hour or so because the battery's about to die.
Is there a certain rom with exceptional battery life that i can try to see if mabye its a hardware related issue? i seem to remember having horrible battery life for the day? or so that i was running stock ATT gingerbread.

I use Aura 1.2.2.2 (debloat) and get average battery life. Comparable to what I got before I installed third party ROM. If you want to try that one and see if its just CM then give it a go.
I had a battery problem after flashing to CM with a previous phone (OG Droid) but it was because I flashed while I had the phone plugged into the charger. It took a while to get it back to normal.
I doubt its CM. I dont know if its something draining your battery in the background or if its a result of weird calibration due to the flash.

my battery life has never been hte greatest but recently i got it working really well
I use the latest weekly build of CM7 and here is what i did
upon fresh install:
wipe battery stats
THEN:
kill battery
charge as far as it will go
clear battery stats (use battery calibration app)
take out battery
wait to reboot(missing battery)
put it back in
let it charge for 2hrs
reboot and unplug
kill the battery
charge to 100% while off (no interuptions)
Enjoy!
i have found that the more cycles my battery goes through 100-0-100
the better it gets
these steps almost tripled my battery life (along with Weekly 3)

there is a bug some people report with CM7 about the suspend process. (i have it, you can search "suspend" in the CM7 thread and see others are as well) load up the app betterbatterystats (there is a thread on xda that has the apk) and see if you have that bug.

I'm on nightly 20 having good battery life

I'm a victim of the suspend process bug
had to flash something else, using ALIEN for now and battery is pretty good

i installed betterybatterystats as you guys recommended and im not entirely sure how to read it but the suspend process shows at the top of the list so i assume thats the process which is eating up my battery? Is there a fix for this? i do like cm7 but if its the rom which is causing my battery life issues ill have to wave goodbye. Does this suspend process but happen on the weekly / nightly builds as well?

I was having horrible battery life as well. I froze some apps that I downloaded from the market and that helped a little bit but what gave me 20+ hours of battery life is the new UK orange Radio that has recently been released. I wanted to flash it since I am using an Orange UK phone and see if it improves my wifi connection, etc....
Reddy flashing a radio appropriate to your device and see if it helps.

I had it on stable, and am on weekly 3 right now. I'm probably going to switch back to a blur rom soon..

My battery blows with CM7. My phone has the suspend bug and nothing fixes it. I tried a fastboot wipe and clean install of the latest stable as well as nightly #20. I've tried several kernels, I'm currently running a screen off profile of 216-216 on the 1.0ghz kernel and I'm undervolted to the max just to make it thru the day.
I'm getting the nexus prime or the iPhone 5 next... which ever is released first.

Constant Battery Drain No Fix Yet

Hello,
Long time lurker here with an issue, I've tried many different solutions but seem to come up with no better results.
The main issue is that my atrix has never gotten better than 15 hours of life. It seems that it is not able to reach sleep state and therefore I get a constant battery drain of ~7.3% per hour regardless of usage.
I am a heavy user averaging 2 hours of screen-on time per day but I experience the same range of battery life (within an hour) whether I use the device or not.
I use background sync setting for google apps (gmail, contacts, music etc), whatsapp and groupme messaging.
I am currently using turl's ICS v6 with Faux123's v025beta kernel. However I've used Neutrino, Wet Dream and DarkSide with similar consistent results.
I recently bought a new OEM battery but that has not affected the run time. The last install of ICS I used the fastboot clean wipe (erase boot, preinstall, system etc) in hopes to fix possible lingering bugs but without any change in the battery run time.
The Atrix is from Bell, tegrapart d00. The screen was replaced once due to the screen becoming non-responsive for touch. Other than that no issues.
Using BetterBatteryStats it appears I have the "suspend" process bug that has been discussed on the forums before, preventing the phone from sleeping. This I think is the main issue, but different kernels and ROMs have not helped it at all. Is this a phone defect type of bug? I don't understand it enough to tell. Also previous forum posts concerning the suspend process have not yielded any types of fixes for it.
Any assistance or help with this issue would be much appreciated.

Switch to Turl v8 with stock kernel and make sure you fastboot -w first

Fixed! I had to flash a new radio. I flashed the 1.77.36P att radio. I had an older Bell radio before. Drain was 7% an hour before, 3% an hour now. Huge difference.

Try the newer 37P radio. It works just as well.

I got same issue as you (I think - can't install betterbatterystats for some reason market won't let me!!!) but I'm already running N_01.77.36P. Was going to reflash, but read the last comment. What is this new radio and can you help me find a CWM zip? no luck in google so far.

Jellybean Battery Drain Discussion

Now, I know that we have a "All your JB discussions here" thread, but I think that this one is a rather specific issue and hence should be discussed in a separate thread. I also know this post is rather lengthy, but please read and give your opinions as it's important.
If you look at the last 5 pages on the JB discussion thread, you'll notice that lots of people are complaining about the battery drain due to wifi. The gist of it is that if you forget to turn off wifi before turning your screen off, then you'll experience a battery drain of about 5% an hour even though you're not doing anything with the phone.
I can vouch for the wifi battery drain issue. After flashing DLJ4, doing a factory reset, doing several full charge cycles, etc. here's what I can say:
On ICS, battery drain when the screen is off is the same regardless of whether you leave wifi on or off. Approximately 2-5% overnight
On JB, battery drain when the screen is off and wifi is off is the same as ICS. But if you leave wifi on, it drains about 2-3% an hour.
General battery use on JB otherwise is the same as ICS
It's pretty obvious. You don't even need to use apps to monitor battery use. Anyone can easily tell that there is something about the wifi causing battery drain.
So there are 2 things to note:
1) Wifi strength on JB is much stronger. For example, I could never connect to wifi from the 2nd floor on ICS (the modem is on the ground floor; it always shows poor signal and gives the "authentication error" when I try to connect), but now on JB I can easily do so within seconds of turning the wifi on. And this result is consistent each time I try.
2) With wifi on and the screen on at the same time (eg: when browsing), the battery drain is similar to ICS, ie approximately 1% every 4 minutes.
Point (1) seems to imply that the wifi strength on JB is stronger, and maybe the frequency used is higher. This seems like a pretty good explanation for the battery drain, until you consider point (2). Point (2) seems to indicate that the problem is not in the wifi frequency, as battery drain during screen-on time is similar (you would expect it to be higher), but there is some other explanation.
So my idea is that the wifi is indeed stronger in JB but that doesn't affect battery drain significantly. Instead, the problem lies in the fact that wifi management on JB is just bad. On ICS, when the screen is off, the wifi signals are probably "weakened" significantly, for lack of a more technical term, but on JB it remains at the same "strength" as when the screen is on. This is probably what causes the battery drain.
I'd like to use this thread to see what everyone else thinks from the experience on stock JB roms. And of course, if we can properly identify the cause, surely someone would be able to fix it.
Update 1: Alright, so far it seems that only those on stock kernels have this problem. Those on Siyah kernel appear to be unaffected. I'll test it out soon, and see if it can be a temporary fix for now.
Update 2: So I've been using Siyah kernel 1.7 RC1 for nearly two days now. While the battery drain due to wifi is reduced, it's still not as good as it was on stock ICS. And this is even after I flashed the "better profile.zip". Also, as a side note, the overall battery consumption on Siyah isn't significantly better than the stock kernel. But at least wifi battery draining seems to be less. Do continue posting your experiences so we can find a more viable solution.
Update 3: Over the last few weeks I've tried out DLJ1, DLJ5 and the leaked Rom with multiwindow (can't remember the Rom name). Anyway, from my experience, and from the collective opinions on people who posted here or in other battery threads, it would seem that the WiFi battery drain persists in all these jb roms. The only solution I've had so far was to use Siyah kernel. Some people report that custom roms work too, but I suppose if you're reading this thread it means you're trying to fix a problem with stock jb.

Wifi battery drain is bad on my s3 too. :crying:
I thought it was just some wakelock issue. hopefully the next jellybean update will fix this

I'm on the latest DLJ4 and I had wifi on last night. I unplugged my phone from charger at 3:00am then woke up at 6:30 for work and in that 3.5 hours I had only lost 2% battery, the whole time wifi was running.
Maybe it's kernel related, I'm running Siyah 1.6.8 and I don't seem to have a problem.

I'm on stock kernel. Perhaps I'll try out Siyah kernel, but still there a quite a number of us facing this issue, as you might be able to tell from the original JB discussion.

I've been on Omega since version 25 (now on 31) and I have 0.9% per hour battery drain with WIFI on. I've used BBS and found all of the main drain causes on my phone and stopped them. For instance, I have location services turned off and even disable\freeze maps when the screen turns off (I have a tasker widget to defrost and open it when I want it).
On my phone the OS doesn't have a problem with WIFI battery drain, but various apps and services did until I sorted them.
Edit - my drain is the same despite whether I run stock kernel, Phenomenal or Siyah.

I'm on siyah 1.6.8 and have no decreased battery life.

Proper testing from those with no problem is the only way you can prove that WiFi is stronger .

Well are you sure ? please answer My problem is the WIFI speed su** it always shows no bar or 1 bar all the times and speed is horrible after seeing your comment i think JB update is worth a shot

Maybe we need to add:-
These problems are only on stock jb roms, not flashed kernels or custom roms. A large amount of people on stock firmware on jelly bean have this WiFi drain. Its very obvious on my phone, with WiFi on and screen off, I get around 4-5% drain, with WiFi off and screen off I get about 0.5% drain.

And I thought that this problem on my phone only ... I wanted to do a factory reset, but you say it doesn't help, so no point trying.
With the JB benefits, there are still annoying bugs.
1. When accessing a Settings tab, notice how it opens. There a chubbiness in the Settings app. (tried to clear data etc etc ..).
2. TouchWiz Redraws very frequently.
Other than that, I can't see any problems with the Official JB.

I don't get drain Lj4 WiFi on overnight max drain 2-3 %

I know these aren't methodical tests, and they're still quite subjective. But it's pretty obvious to most of us that the wifi is stronger. By the way, what do you mean that you don't see that sort of drain? On ics or jb? Because on both ics and jb, my battery drains about 1% for every four minutes of browsing and I find that normal; pretty good even

I'd like to add that after I installed the stock jb it wasn't the WiFi I had a problem with it was my network connection with virgin as my signal was very low, about only two bars and my s3 used to get very hot when it wasn't doing anything.
After I left my screen off overnight and checked bbs I found that the main problem causing battery drain was losing connection and bad connection and my s3 got hotter the more it charged.
I tried the Shiyah kernel and flashed the even more battery zip I've notice that I now have a full connection and it hasn't dropped out yet and my battery is draining very slow and my s3 is very cool which I am really happy about.
Edit:After a full cycle the quad core seems to be draining less, seems the Shiyah Kernel is the best Kernel for battery life with Jellybean

But wanna thank this thread hopefully changing kernel will help

I've just noticed something after using stweaks, if I change to dual core my battery drains slower and the Celsius of the phone is lower but if I have it on quad core my battery drains really fast and the Celsius is much higher.
I read somewhere that it's only the international versions of s3 that have bad battery drain and the other versions use dual core, not sure if that makes a difference.
Also noticed after changing to dual core my s3 only lost 4% over night, I also undervolted the battery a bit.
I installed the wattage widget to see the differences.

How about folks running stock DLJ1/2?
I had flashed DLJ2 French stock version previously and I feel I had better battery at that time than DLJ4 UK unbranded JB (which I am on right now).
And I dont think we are getting enough complaints about battery life from folks who are running versions other than UK DLJ4 ROM!

I opening this thread especially for discuss AOKP nightlies, not for Milestone. I did not find separated thread here in XDA for nightly versions of AOKP. I think AOKP deserves a thread here.
To keep clean the AOKP Milestone thread, I suggest to post here any aokp nightly related issue/question.
If you want to post here, please do not forget to report which nightly version you are using currently. In this way I guess we can help each others more efficiently.
Latest nightlies can be found on AOKP website.

obviously milestone version will be better than nightlies.
i plan to flash back milestone one. since i dont use the new things in the nightlies.
the only think i notice to be different is the auto brightness customization and the ribbon.
the android OS drain is too high.

Hi Guys
Strange things just happened.
Im still on nightly with my phone. i have some battery drain by android OS.
BUT
on my nexus the milestone version runs. Its already works good more than a month. Yesterday i noticed the same thing. Android OS drains the battery, more than the screen itself.
I started to find applications that can drain the battery through android os.
No luck. Im sure its not any installed application from playstore.
It must be the Google Apps itselt that the same on my both device.. Between gapps im sure 'currents' is a big battery killer. first i uninstalled and got better result, but still androis os drains the batteries on my both device.. Im pretty sure they are updating themselves without any question. so this battety drain not comes with aokp nightlies, but google apps. and that more frightening: together android os battery drain i noticed mediaserver also works even if i dont watch any video and my phone is muted.... what if google spying on us??? very strange.. I'll try to use my tablet without any connection, just for a test...
Android OS secrvice alway was around 2-5% from a full battery.. even if the device is idle!!!
do you guys experiencing the same behaviour by android os??

My grand grandfather was an astronaut!

Good news!
I did find the problems!
its about google apps....
i uninstalled google currents
and disabld everything in the location settings.
now my battery drain stopped!
in the last 6 hours of idle, drained only 1%!
it seems much better now.
Im still on 06-15 niggtly.
Same thing solved my problem on nexus 7.
So I guess this battery drain not come from any aokp build! If you want, you can install back the latest nightly (imo same stable like milestone was, however i dont use the built in lock screen and i saw peoples having problem with it.).
good luck!

Hi, I have high android OS usage even though I clean install the milestone one.
Like u said, the android OS usage is always Slightly higher than screen usage.
Better batter stats doesn't show any partial or kernel wake lock.
I suspect it may be the auto brightness.
I have mine completely customized to my own values.
Maybe it's causing the phone to constant check the light sensor.
I have disable the auto brightness and will check how it behaves.

hi
on my device auto brightness fully disabled i using constant 1% brightness because i alwasys inside... I think you dont need to affraid because of that.
i guess its google apps
go to application and check google services thats already updated. you can delete update.. so i think google services can change in the background.
i also started use better battery stats. i'll let you know if i have some news.

Recently came over from CM, needed more customization. AOKP has been great, but has a couple of weird bugs on my device. Most notably, occasionally the multitasking pane has no quit all button. However, all I have to do is leave and immediately reopen the multitasking. Doesn't affect much, but still a minor annoyance. Still, having a blast playing around with all the customization, I feel like I'm just scratching the surface.

I had the opposite experience. I tried cyanogen mod yesterday.
And was underwhelmed by the lack of things in cm. it lose to aokp in so many ways.
But there are 2 things cm does better than aokp, the torch toggle that leaves a notification in the status bar to be turn off.
And remap volume button to control media volume instead of ringer volume.
The multitasking plane has a kill all button if you enable it in rom settings under general.
I do not face bug where it randomly disappear. If issue persist, you could try reinstall rom.

Fast summary about battery drain problem
After I did try different variations of roms and modem versions (basebands), I must say that: nothing is draining the battery because of AOKP, just looks like...
I feel my battery keeps a little longer with XXELLA baseband than XXEMC2.
In my opinion it's just a bad battery statistics that misleading us.. Somehow in the battery log "Android Os" almost always comming up to the first place, even if that is impossible and not logical.
Just for an example:
Charge up your phone to 100%, then do not switch off your phone.
Switch off everything that can eat extra battery (bluetooth, wifi, mobile data, nfc, gps)
Try to watch movie from your sd card or do anything to drain your battery to approx. 80%.
You will see in the battery log: Screen or/and media is the biggest consumer of the battery.
Leave your phone in idle for 6-8 hours long, then check again the battery log.
Probably your battery losts another 1-2%, but Android OS will be the bigger consumer again, thats logically not possible...
If the battery lost 20% because of the screen, and another 1-2% because of idle: Android OS can not come above the screen time with total 1-2% of consumption.. So its false, we dont need to talking about. Its a battery log bug. I guess the very high numbers of kernel wakelocks mislead the calculations of the battery stat. I also noticed that my screen time changed to less. Certain parts of the battery log was missing or/and incorrect: I did not see screen in the list two times, and once I did see bluetooth as bigger consumer (wih 68 hours!!!) even if i did not use any bluetooth connection. I did try battery calibration - not helps.
Any Nightly version of AKOP don't eats more battery than Milestone!!!
6-16 Nightly is stable on my device, no random restarts or any malfunction, superuser works better, camera bug also fixed
Only thing that I noticed as difference is between basebands:
On my device XXELLA eats less battery [0,25%/hour] in idle, than XXEMC2 [up to ~1,25%/hour - variable sometimes less]
I living in the European Union, so I can't suggest to everyone to use the mentioned version of baseband, But if you notice more battery consumption in idle, good idea to try another (maybe older) baseband version that suggested in your area.

If someone is noticed that: AOKP's headphone output much louder(and distorted) than Originally SGS3 with stock rom, Here is a quckfix:
Use any root explorer (I did use AntTek Explorer - works good and free), make sure it has root privileges.
Go to: System>etc >sound where is a file located, m0
Open the file for edit
Search the section that starts <device name="headphone">
In this section you will see another two row:
<ctl name="Left Output Mixer DAC Volume" val="7"/>
<ctl name="Right Output Mixer DAC Volume" val="7"/>
Set the values from 7 to 4
Save the file
Restart your phone
For me personally not necessary to pumping out my brain with headphones, so I rather need quality sound than high volume. I always using Poweramp and after the change I noticed: I can boost more bass and treble without distorting the sound...
Overally I'm not satisfied with the sound quality of s3 (my old galaxy nexus was much better imo), but with this settings, sounds much better for my ears... If someone is more audiofil, just like me: I suggest to try this settings.

[Q] What's a relatively stable ROM to replace CM7.2?

I currently have CM7.2 on my MB525.
There seem to be a billion options out there. What's are relatively stable ROMs of newer versions of Android for Defy?
I don't mind a few bugs as long as the basic functionality (GPS, Phone, Camera) works fine.
Thanks

4.1.2
I tryed some 4.1.2 and they seems to be stable. Except my latest try with slimrom that have nonworking wifi tethering and the one before this had broken pitch sensor.

Try illusion 2.1,its based on 4.2.2,
Very stable,
Or try xperia d 4.1, based on 4.1.2,
Much stable

i'm sticking to epsylon's cm9.1 for now, at least until and unless they fix the problem with the "android os" battery draining issue.....

Well I'm not experiencing any battery drain even though system settings show android os as the main consumer. I get 1-2 days of battery life with android os as the top consumer.

well fortunate for you,but unfortunately not the same for me. when i left my phone overnight for about 10hrs with everything off (wifi, gps, sync, data) and only with mobile phone radio on (for phone call), i got the following results (as best as i could remember from memory):
1. epsylon's cm9.1 - about 0.4 to 0.5 % /hr battery drop. battery settings shows roughly:
phone idle 54%
phone standby 40%
android os 4%
note: now this is what i expected for a phone that is on "real" idle/standby!
2. quarx's cm10 (4.1.2) - about 1.1 % /hr battery drop. battery settings shows something like:
android os 60 to 70 %
screen 20 to 30 %
follows by phone idles and others.
note: i know i quoted about 2% drop in one of my previous post at quarx's cm10 thread, but i've edited that to say it was because the battery calibration was way out (after flashing cm10 about 10 times trying out every possible ways like different gapps, settings, wiping etc). i did use bbs (better battery stat) apk but it was too complicated for me to decifer, so i didn't bother.
edit: not only android os obviously indicating that something keep waking up to do something but possibly flashing the screen as well? i mean how could the screen percentage be 20-30% when the phone is just sitting there with screen off for 10 hrs??? unfortunately no one seems to care!!!

I think I know your problem. Android OS must be keeping your phone awake. Happens to me sometimes. Toggling Airplane mode on and off, or a reboot usually fixes it. Also using defy full wiper when starting is advisable.
Edit - I think you should test CM10 once more. I normally get 0.3-0.4% per hour on standby.

if i can get that sort of battery usage i won't be complaining either which version of cm10 are you using? i believe i was using the july 3rd version as some people recommended that to be the most stable. can't remember if i've tried the latest sep 18 version. i'll give it another go this weekend and let you knowm the results. thanks for your helps btw.

I'm testing the latest version by MarcinRN. It's surprising because my battery is almost 2 years old now.:cyclops:
EDIT - Test it out, and give BBS stats after 2-3 days. Also, restore all your apps, because some app might be rogue.

i'm back. thanks for encouraging me to try it again. don't know what i've done different this time but the latest 20130918 version is now giving me 0.55-0.60%/hr battery consumption and following stats:
android os 70%
cell standby 23%
phone idle 8%
well i'm happy with that since gingerbread was giving me about 0.7%/hr anyway. if they could fix the android os problem we might be able to get the same consumption as cm9.1 though.
details of how i flash the rom this time:
1. wipe/format the phone with defy_fullwipe_ext4.zip (proper wipe/format).
2. flash 20130918 rom.
3. flash cwm_twrp-forjellybeanroms-v2-signed.zip (for safety).
4. wipe cache and dalvik.
5. reboot. (want to test rom without gapps first).
6. switched of all signals (data, gps, sync, bluetooth and wifi) except phone radio.
7. toggle airplane mode.
8. reboot into recovery and wipe battery stat.
9. reboot phone with charger in.
10. charge phone to 100% and left the phone on standby overnight (about 10hrs)
11. checked battery stat in the morning and got about 0.55% /hr.
12. reset all settings to my liking, fresh install all apps i used, switch baseband to my region and reboot.
13. flashed tjkv's minimal gapps and reboot.
14 checked battery % before putting phone on standby for another 10hrs. got about 0.58%/hr this time. very happy
thanks again hotdog125. and my apology to the op for taking up your space. hope you found your perfect rom.
