Since we have Q&A stickies in the Inspire and Captivate forums (as well as a few other fora around here), I thought we need a general CM7 Q&A here for the Atrix.
BEFORE ASKING QUESTIONS IN THE FORUMS, ASK YOURSELF:
Has this question probably come up so often that there is an FAQ that includes it?
OFFICIAL CM7 FAQ FROM THE ATRIX-DEV TEAM​
Phalanx7621 said:
I know how much people LOVE to post questions in here as if it's the CM7 ROM and get all pissy about how things dont' work, but keep in mind that if that were true and a bunch of stuff didn't work it would NOT have been made part of the nightly CM7 releases. Also, it wouldn't have been released if that were the case. The devs work very hard to make sure most major problems are taken care of before every release, but if yer flashing A NIGHTLY, keep in mind it comes with NO promises of functionality and it is STATED in the OP that it shouldn't be used as a daily driver. So if you have a stable version, such as the lastest stable version found on the development page OP, then post a question or comment here after searching for the answer with search feature here and google. Otherwise, there's a Nightly post section as well in the Development side if you wanna look there and that's what yer using. Most of the time if there is a major issue and you can't find it on the bug tracker than it's yer phone, or something you have installed that is messing with the functionality of the ROM. Lastly remember folks, it's the developers job to make their product work with the ROM, not the other way around. Have fun, happy flashing!

You know what ? Its a damned good idea. Too many people are cluttering the development thread. Now since no one else has posted a question related to CM7, I have one:
Can someone help me figure out what is eating my battery on standby ?? I don't have that power hungry facebook app and I did some tweaks found ( via SetCPU ) that I found in the development thread, but it made very little difference. The thing is, I just have no idea how to monitor what is using all the power. How did they figure out that facebook was causing a big drain ?
Do you use google latitude?
A very good thing is use BetterBatteryStats to really understand where the CPU is being keept awake. The embed battery stats for example only showed me Android OS as a culprit, but gave me no further details..
my 2 cents
i have heard CPU Spy is great for figuring out whats using up your resources. dont know as i tend to get pretty good battery life (16+ hours with exchange push enabled)
Thanks for the tips. Yes, I do/have used latitude. I'll put an end to that and give those apps a try. Will report back!

Had anyone else had trouble getting the hbogo app to work on CM7? I can login and try to play a video but get audio with no video. The hbogo splash screen plays perfectly when playing a video for the first time.
Edit: Just found a bug report for this exact issue. (issue 163, sorry, I can't post links.)

When I receive a call, my phone goes to a lock screen, I have to swipe the lock screen to answer. On stock, when I got a call, the screen woke up in the dialer app and all I had to do was press the answer button. For the life of me I can't seem to find a setting to change this, any input appreciated.

Do you by chance have Tango installed? I had it for all of 2 days and noticed my battery died about twice as fast as it normally would. I usually get a good 16+ hours easy with moderate use but was only getting about 9 with the same usage. Did a quick google search and verified tango was the culprit. Uninstalled and back to normal. I don't know if this applies to any other video call apps but might be worth looking into.

Think I already read something about it, but cannot find right now... What's the deal with /mnt/emmc and /sdcard in cm7 ? Is it possible to get it back like the stock rom ?
I am having problems using Titanium and taking screenshots, think it is something related...
Thanks in advance!
Wifi connectivity drives me nuts on cm7. Had to turn it off and on in order to connect. Someone mentioned to edit propbuild. Idk what that means.

You need to go into Setting/CyanogenMod settings/Application, check "Use internal storage" then reboot your phone and it should be back to how it was before.
Betterbatterystats seems to have found some interesting things. Phone on for 1hr and ten minutes.
Under partial wakelocks:
Lightflow: 1hr10m3s
AlarmManager: 58m13s
JuiceDefender:55m44s
There is more ( I can provide screenshot if required ), but those are the top three.
I do find this a little odd. Juice defender was just installed the other day and I can't see how it would cause any problems. Battery was a bit crappy before and didn't get any better/worse. I froze lightflow the other day and battery drain was about the same.
filthyfnj24: Nope no Tango.
I can provide a list of apps if would help as well.
I got watchdog and Im able to detect what cause battery drain while on standby. Its the "suspend" service running on the background with 90% cpu usage ... as soon as I heard the warning from watchdog, I wake my phone and that "suspend" stop immidately. Happen to me since I got this rom cm7. It didn't happen before on alien...

EDIT: upon further investigation I have narrowed down AlarmManager as causing a lot of partial wake locks, but I dont have any alarms set and have not synced my calendar and have the Calendar alerts turned off. However Suspend is showing as a problem as well.
I'm using BetterBatteryStats, SpareParts, and the stock battery manager to try and track this down.
Well, after eliminating Lightflow and turning off Beautiful Widgets small weather, things are improving. Instead of losing 5% per hour on standby, it is now down to about 3%. Juice defender and Alarm manager are still at the top of the list, In 2hrs and 18min I have:
Alarm manager 33m12s
Juice defender 27m56s
So, Juice Defender is next on the list. The funny part is I know that CM7 is causing this. Battery used to last near forever on standby.
Great idea... Stickied. You may also want to check out the atrix-dev-team FAQ and consider suggesting Q/A posts from this thread or links to other posts in other threads, for updates to that FAQ.
Ever since I upgraded from pre-beta 4 to Beta, my phone has had two horizontal deadzone lines on the touchscreen. This persists from ROM to ROM, and is getting to be annoying. I have no warranty, as I bought the phone from a guy who won it in a contest, unlocked it and brought it to another carrier.
Is there any chance that this is a software issue, and can be repaired?
I got it !!!!
Alarm Manager is no longer a problem. Phone now sleeping correctly. I disabled background date, topped off the battery and verified via Betterbatterystats. Now if we could disable background data while it sleeps and re-enable it when you wake it up then we'd be set.
I have been struggling with trying to figure out if the battery life I am seeing is what my Atrix is really capable of. I am occasionally a heavy user, but on weekends I am a very light user. I'll start at 8am with 100% and be almost dead at 6-8pm. I have searched around and seen other Atrix users with 24 hours of battery life and even if I tried my hardest to not use my phone I wouldn't get those kind of numbers. I feel fairly confident in saying i scoured search results and tried everything i could find to extend battery life.
Am I doing something wrong?
Is there something I can do to help?
I know it's been asked before, but I am hoping to get some current answers for this question: what kind of battery life numbers are you getting on your Atrix? Which rom are you using?
Atrix 4G running CM7 RC3. If the answer is "keep it charged as often as possible", it is what it is. It would be great to find an answer to why battery life is so much shorter than others though! Many thanks in advance.
Just noticed CM7.2 stable was released, upgrading to that now to see if battery life improves. Might try a full wipe to see if battery life is better without email, syncs, etc. etc. if the upgrade doesn't help.
i would recommend getting cpu spy and also download and install as a zip 'blue sleep fix' (blue sleep zip can be found in the CM7 thread). This has greatly improved my battery life.

Which kernel? Flash Faux 1.0GHz and undervolt across the board by -50mv. Instant battery life!
Also, use ROM Manager or equivalent to stop all non essential apps from starting on boot.

Test your settings for a few days. If the phone stays stable THEN you set at boot.

Err, that is not good battery life at all bro. I can tell you barely used the phone. Atrix should be able to provide up to 2 days standby time...
I wouldn't undervolt either, I read on these forums that the battery gained from undervolting barely makes a difference

You should turn wifi off when not in use, that will save battery life.
Badass battery will let you know how you spend your battery by % and let you know which app takes the most battery. (Lets you get a really readable easily understandable battery read out.)
I can help you get even better battery if you use this app and give me some numbers (it has a share via gmail/etc)

turning off wifi is not going to help him that much. I leave my wifi on all the time no problems, make 2 days light usage no problem.
More likely he's got some apps running around in the background. I suggest he pick through what he's got installed and start turning off the things that like to sync all the time in the background.
I think step number 1 would be to install a non-stock ROM and startover fresh.
Blur-based ROMs (Nottachtrix was really good) then the faux123 kernel then slowly start installing the apps he likes to use and monitor battery life. It might take a month but he's definitely got an offender here or there causing these problems.
also install Juice Defender. My mom's Galaxy S2 was having tons of problems with battery life even though she wasn't using it at all, 60% battery life at 3pm without using it at all, installed that and immediately helped her a lot, like 80% by 3pm WITH use.
Also, clear your dalvik cache. After installing lots of stuff and not using it, it just fills up with sometimes poorly written code. Clearing it always makes phone faster in my experience.

I think this is what I will do today! I'll do a nandroid backup, and try Nottachtrix with no extra stuff installed or setup. I will report back! I appreciate all the help to get my phone performing where it should be.
Just wanted to report in. I tried a clean ROM as stated in my previous post with no luck. I just couldn't get past the battery life I was getting with cyanogenmod WITH all of the apps and syncs enabled. Should I try another ROM maybe?
Maybe your battery is just a bit old? After ~2 years, you can expect that battery life drops dramatically. if you are a heavy user this might happen earlier. Maybe check with the battery of a friend of yours whether it's a software or a hardware issue
Nvmd
You could be right, the battery might be dying.
I was on vacation the past few days so I got the opportunity to not use my phone most of the day (job requires me to use the phone a lot). The battery lasted about 12 hours and looked like it had about 4 hours left. So maybe I am expecting too much, but I'm not trolling...no.
If you aren't going to be helpful, go somewhere else. You could have said "Your phone screen was on for probably longer periods than the average user and that's why you can't hit longer hours". Based on your previous comments, I shouldn't expect much from you though.
Many thanks to all who are helping me. You're all awesome.

11-12 hours.
I also have 11-12 hours with 1 charge. And it is not enough for me. I use only Whatsapp ( a lot usage ), a little bit browsing, 20-30 minutes phone calls. These are all. And 11-12 hours is sooo bad for them i guess.
I have an "suspend linux process" drainage issue. Maybe because of it, I'm getting this result.
How can I extend my battery life. PLEASE Help!
Hi guys,first sorry for my bad english.
All began few days ago,charging speed become very very wierd like 0 to 100 % takes 10/12 hours...I do admit its not first time had this but iv repaired that with changing kernels but not this time.Thats the first issue.
Other issue is the battery life decreased rapidly.From 61% to 0 battery widget said it need arround 1:50h to deplete while IDLE.I mean i wouldnt ask for any guidence here if i wasnt able to figure it out by myself.
For all saying dw battery stats i did,and nothink major that other than Clock widget made some huge wake locks and kept device quite hot so i disable it.
First time all this occured was while i was using Buzz Launcher and tougth the drainage may come from it so i switched to Nova launcher.Im using Ultima rom currently with Siyah kernel,and i did try all kerneles with all possible settings and nothink either repaired the battery to go further than 5/6 hour lifetime or charing speed.
So tommorow or today idk ima go to visit the shop that bougth phone from and demand to change my charger from wich i know my first issue is from but i really am afraid if the battery isnt screwed also so to ask for change also.
Also iv done wipes/caches wipes everythink,Ussually helped before but not now.
MY question is can that baattery performance now sucks cause the terrible charging speed that is on now????I want be sure or see if someone had this problem.
Thanks
Given the number of kernels you've flashed I'd suggest going back to completely stock rom and kernel to test.
The original chargers are prone to failure and your battery is only guaranteed for six months, as this is a consumable item for regular replacement.
Also, questions go in the q&a section to reduce clutter in here.

Done it for the op
4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this

Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?
I live in Denmark. I ordered it off Ebay, but I see now that the UK shop I got it from doesn't ship to India.

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.

As far as the battery issue is concerned,do a clean ROM install through Odin.

Hi everyone!
Some days ago I bought a new battery for my S3 (seller said to be genuine) and I am disappointed because its performance is almost the same as the one I was experiencing with my old battery (18 month-old battery). For this reason, I have been researching and I have done this until now:
*) Being honest, this comparison is somehow subjective since apart from the battery change, my S3 was officially updated from 4.1 to 4.3 almost at the same time I changed the battery. Then, I wonder whether this update may have affected my diagnosis on the battery duration.
1) According to the point * I decided to do a battery calibration "without root" consisting in draining the battery to 0% and charging until 100%. I haven't seen any improvement doing this.
2) As consequence I analyzed wakelocks. I have addressed two of them from the System:
- AudioOutLock. to fix this one I did as recommended: disabling sounds when typing and all of this.
- Backup. Fixed by disabling the backup from Google (I would like to have it enabled but if it is causing a battery drain...)
3) I let the phone the whole night turned on with the 3g connection on and I got a ratio of 2%/hour draining. I have read this is more or less under the normal parameters.
After doing all of this I'm still not happy with the performance. Usually, my mobile gets under 20% by the end of the day with the screen on in a range between 1h30m and 2h. If I remember well at the very begging (when I bought my phone), I was getting my phone at 20% by the end of the day but having the screen on for 4h or more. After buying a new battery, I was expecting to return to that situation.
Do you have any hint? As for example a better way to calibrate? Factory reset may help? Should I check a specific wakelock?
Thank you very much in advance!
I forgot to mention that when I let it charging over night, my s3 does not always charge until 100. Sometimes it's until 98 or 95. I don't know if this helps you guys as a hint but I want to provide as much information as possible.
Thanks

Thanks!, I will check. But so far I have briefly seen it looks like there is not a specific solution more than disabling gNow and some other things. Maybe a good option is to downgrade or using a custom rom in which there aren't these problem.
its same to me.
aftet update 4.2 to 4.3.

Hi, look for XDA-forum "Better Battery Stats", there is an excellent tool to analyse battery drain and the community in this thread provides very good support.

Thanks!. I have been using Wakelock detector but I will try with this one. I was wondering if using this kind of applications for checking the wakelocks may provoke some battery drain itself. I mean, should it be used just for analyzing when you experience a battery issue? or should they be permanently installed no matter whether you have battery problems or not?

Hi, Better Battery Stats is using an already existing process of Android to obtain it's information, therefore the influence of the app itself on battery drain should be negligable.

Thanks for the info!. I have not seen anything special in the partial wakelocks. In the kernel wakelocks, it is difficult to distinguish whether one entry is specially problematic or not. After what I have read so far it may be the mix of social apps I have now installed:
- Whatsapp
- Twitter
- Messenger (FB messenger)
- Line
I guess maybe I have too many of them reason why the battery is draining more than normally when the screen is off

Which firmware you are using. .Sometimes it's the problem with the firmware. .For example GML2 and ML4 version firmware has a pretty bad battery drain. ..

mk6 is fine with the battery...so firstly install an app called better battery stats search for it...install it and let the phone to be in standby mode for 4-5 hours..and then see in partial wakelocks and kernel wakelocks..and post those screenshots on bbs thread...someone will surely help you..
sometimes changing kernel could solve the problem..boeffla is the one i am satisfied with..and agni kernel is also one of the better kernels..:good:

Sorry for the delay to answer, I've been busy. Here I post the images of the battery stats. Sorry, they are not what you told me to be having them 5 hours quiet (that's difficult for me). However I can tell you that the 40minutes of screen on where just chatting on whatsapp or checking emails; no angry birds or need for speeds hehe... Are these images ok to be posted on the thread you told me? Thanks in advance!
I had a poor battery perfomance after upgrading from 4.1.2 to 4.3 until I've disabled fast dormancy. It seems that in v4.3 is enabled, and if your carrier doesn't support it, it will eat your battery. Donwload free from market "fast dormancy togle" by Siyah, and that's it

I have just rooted the phone and disable the fd. I hope this works!. Thank you very much for the info. However, now that I have it rooted, do you suggest to install a custom rom for getting a better performance? if so, which? there is a good one with 4.4 and multi-view?.
Thanks in advance!
Try flashing allblacksback mod it makes the whole system dark and saves battery on display and also I recommend disabling Google play services but this means there will be no push services but it saves a lot of ? ? ? ?

After giving a try to the idea of disconnecting the fast dormancy here I give you some reports on the battery consumption. I don't know why but statistics are wrong from the point of view of the duration (3 days).. since I disconnected it just 10 hours ago. I think its consumption is still huge. I hope you can give me a hint on it. Thanks!
Ive installed smartdroid. Battery perfomance seems quite better now! What do you think from the screens? However.. i find the screen too much consuming.... ive seen people managing 5 hours of screen in a day. Why i am not? May it be battery or configuration?
Thanks!
Do you have any hint on this? Ive seen that with the screen off the consumption is really good. However, with the screen on a doing normal stuff: chroming, feedlying or whatsapping it goes to a 20-25%/h.
