Hello everyone! I would have posted this in the actual GSB thread but I don't seem to have the correct privileges yet so I am posting here instead.
First off, I just want to thank workshed for his awesome work. I really do love the ROM and everything about it. However, I have a few small issues with it that I can't seem to figure out.
First off, my battery life is terrible. Take yesterday for example. I used my phone probably twice to send some texts in the morning and to check the time. Charged it throughout the night and pulled it off the charger when I woke up and began my day. Within two hours, my phones battery was down to 75%. Five hours later, it was completely dead and I hadn't even used it.
My second issue is with settings. For some reason, when I reboot, some of my setting don't get saved. The one thing that really bothers me is the keyboard. I have Swype installed and every time the phone shuts off, I have to go into settings and re-enable Swype as my keyboard. It is just a hassle and is kind of frustrating, especially when I forget to do and then go to send a message.
Other than those two issues, I absolutely love the ROM and wouldn't change it for anything else. Anyone have any suggestions for what I can do about my few issues?

Recharge it until you get a green light. Restart the phone in Recovery, go to the Wipe menu, and wipe the battery stats (I'd keep the phone on power for this.) Restart the phone, pull the power and use as you normally would. Ignore anybody who tells you that you must run the battery down until the phone shuts itself off - this is really not great for the battery (though once a month or so isn't bad), and really isn't necessary for the battery calculations to reset themselves with new usage stats. The longer you can go the better, but it's not necessary to change your phone usage habits so that you have a completely discharged phone.

Thank you for that information, I shall try it out and see if it helps!
I also forget to mention one more error. Whenever I boot up the phone, my Facebook account sets itself to not sync and I lose all my contact pictures. I then have to open the Facebook application and set it to sync again.
EDIT:
Sorry, didn't realize it was a double post!
My battery life is similar to the OP's. I can make it through the day, but since I am ususally down to about 60% by one or two pm (from 6 or 7 am) I prefer a mid-day charge just to make sure I can last through the evening.
I just flashed [ROM][3/22/2011] GSB v2.2 | GingerBread 2.3.3 [CM7.0.0 RC2 NIGHTLY] a few days ago and it has been running great, but I noticed that my green light (battery fully charged) now comes on @ 90%.
Before it would not turn from amber to green till 100%. Should I wipe battery stats?
Under battery use (sry no screenies) there is nothing unusual:
Display @57%, everything else under 10%.
But when I checked Spare Parts I noticed that my little Eris won't sleep!
It looks like Android system is the culprit, keeping a partial wake lock.
Battery History in Spare Parts:
Other Usage - Since last unplugged
Running 100%
Screen on 13.2%
Wifi on 100%
Wifi running 91.6%
Partial wake usage - Since last unplugged
Android System almost a full blue bar, all other apps minimal bars
The phone has more or less been sitting at my desk at work in wifi with light usage.
Anyone have any idea why Android System is trying to eat my battery?
i had battery problems on gsb its a great rom. i switch to ginger tazz. with tazz's rom i get more then 20hrs b4 it says to connect charger thats with the display on about 4 hours and wifi on and running facebook tapatalk calls texts and whatever i think of doing.
I'm running GSB 2.5 CM RC 4 and I now have been able to get 25 hours with 70% of battery left. I used to be able to get maybe 24 hours before it died. Now your mileage may vary but this is what I do. I removed Task Killer which was eating a bunch or the battery and after a visit to Amazon's app market their little app was running all the time along with Weather Bug so both of them are now gone. and finally I turned off auto sync ( I can check my email when ever I want and it takes a lot less battery). By turning off auto sync that was what really made the difference for me. Of course there are many things you can do but running WiFi will kill your battery faster than 3g (or at least it does on mine) and I have the screen brightness set at 18. Just a note I leave BT and GPS on all the time when they are not being used an are in standby their usage is quit small.
What works for you would depend on if you want your email pushed to you all the time and if you have to have your WiFi on instead of 3g.
Again it's just my observations for my phone.
Really you should just do the first suggestion and recalibrate your battery.
Also if you read closely in workshed's log, he specifically said to a full wipe not only formatting external memory but also doing a dalvik/cache wipe. You may as well also wipe the battery stats while you're at it.
Personally I'm running GSB 2.5 and it's simply amazing. 60% of the battery gets me from wake-up alarm to nighttime charge.
Hope you figure it out!
After I installed GSB 2.5, my battery also seems to be rapidly discharging. Takes less than an hour of no use, wifi-on to drop from 100% to ~80%. I did a full discharge calibration on my battery as soon as I flashed to this GSB 2.5
I will attempt the simple batt stat wipe at 100% and see if that helps at all. I'll let you guys know.

Hi,
I'm currently using JuicePlotter to see how my battery drains over time and this past night I think it drained more than it should (or maybe not).
For the ones who don't know, JuicePlotter runs in the background (of course) analyzing your battery, that too wastes battery juice of course. Thought, the app dev says on his website:
Perhaps the most important feature of JuicePlotter is that - unlike all similar apps and widgets - it's very battery friendly;

So I'm not sure if the problem lies on JuicePlotter or not, I'll have to test it one night without it...
This is how JuicePlotter displays it's graph:
The coloured bands along the graph show your screen brightness, radio usage, charging status and battery temperature. Just scroll around to find precise information and make sense of the different colours.

I went to bed at 4:10 with the battery at 97%. Around 13:00, it was at 89% and I didn't receive any calls/messages/mails/whatever during the night. The WiFi/3G was off all night along with the screen of course. The battery temperature remained the same too. I don't know if it makes a difference but I normally turn off Auto-Sync if the WiFi is off too.
Is it normal to lose 8% of battery juice in 9h in standby? I think it's a bit too much, but I don't know... Does the same happens to you too? What else cloud it be?
Interesting looking app. I've never noticed much of a lose overnight. Just installed the app, will fully charge and give you an update tomorrow.
Also how's the cell reception in your area? I've heard it can drain the battery a far bit if the reception is low.
Sent from my HTC Hero using XDA App
I'll have to do more testing but I think it's the app's problem... Tonight, I went to bed with 83% and it was exactly the same when I woke up...
I fully charged mine last night and turned on JuicePlotter. Still showing 100% this morning. Both in the app and on the phones battery indicator (in the notification bar). Do you know of any other apps similar to this that could be run in tandem?
Weird, Battery Graph also does the same thing...
This needs more days of testing on my part...
My battery goes from 100% - 0% in about 16hrs... doesn't matter how much I use the phone or not.
I have BatteryGraph but the results don't really mean anything to me as it just shows battery life vs time on a scale.
I'll try JuicePlotter to see if I can pin down exactly what's causing my terrible battery life.
I have a feeling it's running at full speed even when in standby but I'm not sure how to check if this is the case. Any ideas?
EDIT: Looking at BatteryGraph I've lost 15% in around 1hr... nothing unusual going on with my phone that I know about... just standard stuff running in the background. Perhaps the battery itself is simply past it's best.

Wow that is terrible, try apps like Taskpanel and when you add programs to your auto kill list the program kills the programs as long as they are running in the background when the screen is off, however if you are on lets say your browser and you don't go to your homescreen the screen goes off into stand by it will not kill the app. Also try draining your battery to the point it shuts down by itself, plug it in let it charge for a bit, boot into recovery wipe battery stats start up the phone or leave it off (your choice) and let it charge fully. Are you using setcpu or OC Widget or anything? If you are using SetCPU make a profile for when screen is off and make it underclocked like 264 Mhz to 480Mhz, or with OC Widget tick the 'use different screen frequencies' (don't remember what it is called since I don't use it) and do the same; I like SetCPU better because when you turn the screen on it switches profile faster where as OC Widget takes its time however with SetCPU do not use the widget it will cause Sense to FC and I'm not sure about Vanilla.
Hope this makes sense since all my ideas are said at once.
::EDIT::

The way I've learned to recalibrate the battery is to let it go down to 5%, boot phone into recovery and wipe batterystats, then power off the phone. Let the phone charge until the green led is on without turning it on. Then turn on and use the phone as usual. Learned it over at modaco. Worked as a charm, and batterytime was improved. I have personally experienced strange batterybehaviour after periods with flashing a lot of roms.

Here.
That's interesting...
Cause I've been playing with ROMs latetly, creating my own, testing hacks and stuff... And most of the time the phone is plugged and the battery is charged, during the flashing process it's using the battery and then it charges again. I also have to leave from time to time and when I get back I continue my stuff, meaning I'm charging the battery at high levels.
I'll have to try that calibrate method...
For now, for the past 2 nights, with JuicePlotter off, I've noticed the battery level did not change at all during the night. Tonight I'm going to try one more time with JuicePlotter on...

Wiped battery stats at 5% last night, let the phone die and then charged whislt off until green light came on. Been keeping an eye on it all day and there has been a noticable improvement.
The phone came off charge at around 2am (so around 12hrs ago) and it has only lost 20%, which is a lot better than I was getting before.
It was probably just due to me messing about with some many ROMs and update zips lately as I tend not to have too much crap running in the background (I use OSMonitor).
I will look into setCPU but I remember trying it before with VR12 and it ended up causing some weird problems meaning I needed to do a full wipe to get everything working again.
Thanks for the help
This night, with JuicePlotter on, I only lost 1%, seems reasonable now... I don't know why that one time I lost 8% during the night. Maybe an isolated case? Something was probably running when it shouldn't, I just don't know what.
Hey guys,
How much battery life do you get on your X2?
I just installed CM7 and I'm down to 60% after 5 hours of LOW use :/. Could I need a new battery?
Are you doing anything with the settings of the CPU, such as setting minimum frequency, keeping both CPUs online at all time (this might be set via tweaking scripts)?
In fact, ARE you using any type of tweaking scripts (V6 Turbocharger, speedy, etc)?
I don't use any of them and my battery life is pretty good. I also have an extended battery as well, so that helps.
Let the ROM settle in. After two days you should get a better picture of what it's like. Don't forget to do a battery calibration. I haven't even done that yet and have been lucky enough to have great battery longevity. Can also look into managers like Juice Defender. There's also another app I have used in the past that can limit when an app can run. Like limit Facebook from always running in the background and syncing for data. Ithink it'd LGE or LBE security?

Are you using the beta and not the alpha? The alpha has a problem with running the CPU at a high percentage when it shouldn't, which cause the battery to suck.
It is possible that you may need a new battery, but more likely is that the X2 simply has notoriously bad battery life. There are, however, things you can try to help. Go to your settings app, scroll down and click on "applications", and from there, open "running processes". Check out some of the processes. There may not be any, and if you see processes running for games or apps you haven't used in the last few minutes, it may mean that they are constantly running in the background. In that case, you may want to consider uninstalling. Try to use wifi over 3g wherever available. Screen brightness is a major battery killer, and as such, may want to keep it on the lowest setting; I've found it to be the most noticeable improvent in battery life. People are going to tell you to calibrate your battery, but I've done that many times on 2 X2s, never seen a difference. My friends and I agree its just a myth, but there's no reason not to try.
Honestly I don't know squat about batteries, but I remember hearing that the voltage of our batteries is 4.2 volts. If that's a measure of capacity like I think, you can try the app "battery left", which I believe has a voltage meter. If its less than that, maybe you should consider a replacement. Please don't take my word on this though, I can't confirm any of this to be true lol. Maybe someone else can offer their opinion on battery health.
This whole post probably seems like a big collection of thoughts. I'm tokin' right now, took me like 20 minutes to type this.
Hope I could help
To add to theredvendetta's comment, if you have your email set to check for messages, it can really have an effect on your battery. If you set it to never check, I'll bet you will see a difference.

I am using the Beta.
@theredvendetta: I installed the Battery Left widget, and when I go into details it's saying some interesting things.
I'm at 50% battery right now. For one, its saying my battery is at 3787 mV. 3.8 volts I would say considerably lower then the 4.3 it should be. My battery is only ~6 months old, but, for 4 of those months it sat unused, uncharged, and in my hot/cold car. I've only run it down a bit and charged it up 4 or 5 times this week since then.
It is reporting "battery health" as good, but idk.
Under "Accuracy" it's saying the charge reading is "Inaccurate" and the bar is totally red, indicating that the estimation of charge is very inaccurate.
Where can I calibrate the battery? I'll look around under Settings for now. EDIT: It's likely I was only around 60% charged or so when I installed the rom.
And as for background tasks, aside from the default stuff and my few widgets (not a heavy user of those) there's just Facebook+Words with Friends, Songbird, GO Keyboard. Not too terrible, I think.

I probably should have said this to begin with, but when I was talking about the voltage, I meant 4.2 was the charge when at full charge. I can see I worded my original statement poorly, apologies. Try charging up to full, and then check battery left.
When it says "innacurate", its reffering to the battery percentage reading its giving you. When you have cycled the battery once or twice, it will tell you it is "accurate", and the bar Williams turn green. You may notice parts of the bar turn green while first using the app; this means its picking up readings for the percentage of battery you're on at the time. I mean if you're on 50%, it will soon turn green halfway through the bar. After you have completely cycled the battery once or twice, it will stay green and accurate until you reset it or uninstall.
To calibrate the battery, you have to enter Android recovery. I can't remember 100%, but I believe that you hold the up volume button while booting up the phone. It may be down, you can try both. Hold it until you see text pop up that I think says "fastboot". When you see this, let go of the volume button, and now hit volume down until you see text that says "android recovery". If you accidently cycle past it, keep clicking volume down, as the list loops. When you stop on android recovery, press the up volume key. After a few seconds you will see a new screen with an exclamation mark. Press the up and down keys at the same time. A list of options will now appear. Don't use any of them unless you know what you are doing. There should be an option called advanced or something similar. Cycle to it by using the volume keys, and hit the power button to select it. There will be an option to calibrate you battery in there. Itbwill take a few seconds, and after that, return to the main menu and reboot the phone.
Good lord that took me ages to type. There's no hope with dope kids.
I feel like a broken record, but again, battery calibration does not do anything. If there's a chance the meter is off, just charge until your battery's voltage levels off and use the battery fully before charging again.

I agree with you. He asked and I answered. 'Sides, there's no harm in trying it, as there are no negative aspects to it.
Im running cm7 and the only mod im running is the 8 touch points. I do have my screen set to the most dim setting thoough. My phone gets unplugged at 5:30 in the morning though out the day I'll talk send some text might play a few games and usually be on the internet about a hour or so. When I get off at 7pm my battery is usually anywhere from 75% to 69%. A few times it has gone 18 hours and only been down to 52%. Give it some time, CM7 has by far the best battery life that Ive seen for this phone.
Yeah, after clearing the davlic cache and going through a few charge cycles, it seems to of improve greatly.
I'm running CM7 and my phone has been unplugged for 23.5 hours with medium usage including 72 minutes total voice call time and I'm currently sitting at 23%, hence my signature lol and this is a stock battery.
SBF'd from my tasty X2 MAXX
give it a few days but cycle it hard, like don't plug it in until you're below 5%. I have the BH6X (1850mAh vs. 1600mAh) so it's not much of a jump in capacity... your voltage should start out right around 4.2v and drop to about 3.5 when it's close to dead. My phone sucks at telling me how much battery is left, it always has, I typically run this thing dead every day, but some days I'll have upwards of 40% left (voltage is still above 3.8v)
I honestly don't even pay attention to the percentage 'cause I can watch an entire episode of beavis and butthead in HD with the brightness all the way up using software rendering (more power consumption) when I'm below 10% and it won't shut off on me.
it takes me almost a solid two days to kill my battery and I've been on CM7 Beta for a week as of yesterday. at first my battery life was absolute crap, but it has improved... every time you wipe the dalvik it'll take a solid 2-3 days to rebuild it. that uses much more power.
I am prepping for CM7 now. With my mostly stock X2 using Juice Defender I am getting about 1.5 days between charges. When I charge I am about 20% or less on the battery and this is with mostly lite usage. I expect once I make the switch it could take up to a week for everything to level out as it will have to synchronize many things because it will be like having a new phone. When my X2 was new it took about a week to settle in and stop the random crashes. That was also about the time the battery improved from about 1 day between charges. I will write back in a week or two once I have my phone switched and stable.
I used juice defender for awhile but I realized I was really only using it to control data. I just keep a data toggle in the notifications bar. It's really not that much of a hassle to switch it off and it reconnects fast enough. Saves quite a bit of battery power. When I was doing that with my extended battery on liberty I could get about three days.
I am actually impressed with my x2's batt life (although it is a brand new batter when I got the phone a few months ago). I used to have the HTC Desire, and it wasn't the greatest with battery life. My bone stock x2 didn't have the greatest batt life when I first got it, and still wasn't a whole lot better with cm7 installed. But now that I have installed miui on it, and screen brightness is about 70% constant, with wifi ALWAYS enabled. I am going on almost 24 hours now (maybe more??) and I am at 57% with little usage. I've used the phone maybe 2 times today for a total of about 10 minutes talk time, I have no 3g/data, other then wifi when I am at home, so I'm sure that has alot to do with it.
Another tip, that probably everyone already knows, and some people say it doesn't matter, but it seems to for me. ONLY charge your phone when it is less than 10% left, and then make sure it is charged for at least 6-8 hours before you unplug it. I know they say the newer batteries are not effected by this but my wife had the HTC Hero (worst android phone ever IMO), but she would charge it every chance she got, even if it was at 80%. Now, the phone is lucky to hold a charge for 5-6 hours with NO USAGE at all (except wifi always turned on). Granted the phone is older than dirt, and so is the battery, but still. My desire still holds a decent charge considering how old it is. I can get maybe 14-18 hours with no use on it (or very little use) with wifi always on (granted, the phone is bone dead after this time though).
I just altered the cm7 performance settings... back to normal. This combined with a custom juice defender ultimate profile has easily tripled my battery life..

Yeah I've seen nothing come from battery calibration. I have problems with my meter some days draining really quick and some days just normal. If it's bothering my I'll do a reset and that will usually sync it up. I'll try the charged voltage level off and empty thing and see if that helps.
Thanks.
First of all, let me say thanks to Scott for all of his work on CleanRom. I know there has been a lot of discussion lately in his thread about battery usage. Some people are getting outstanding battery life and some people can't make it more than a few hours. I have been one of the people that can't make it more than a few hours no matter what I do. I did a clean wipe of everything before installing the ROM and have even tried to reinstall. The odd thing is my wife's phone does fantastic with this ROM. I finally decided to test things side by side lastnight. My phone should have had the clear advantage because I turned off all syncing options and froze any apps that had been downloaded just to make sure there was nothing running. Meanwhile, her phone syncs like crazy to facebook, email, etc and also has various apps running like weatherbug. I let them both sit overnight and after ~9hrs here are the stats I measured:
Battery % left : 79% (mine) vs 88% (hers)
Data used overnight: 75kb (mine) vs 744kb (hers)
Time awake: 3min 32sec (mine) vs 9 min 42sec (hers)
Time in Deep Sleep: 9hr 19mins (mine) vs 9hr 6min (hers)
Everything points to the fact that I should easily have more life left than hers. I am also attaching a couple of screenshots and the betterbatterystats files to this post. Maybe we can track down why everyone's battery life is so different. Tonight I plan to swap batterys between the phones to try to determine if my battery is the problem.
wow that's pretty good on your wife's phone but horrible for yours especially considering you turned off syncing.
I agree. I have no doubt that her phone could easily still be at 95% or more if I made all of the same adjustments to hers as I did to mine. That is why I am hoping someone on here with more knowledge about this stuff can help to determine what is going on.
It honestly might just be a faulty battery, I was having similar results with mine and my friend's phone, too. I tried multiple ROMs, Kernels, etc. But it slowly got worse and worse to the point that I would go down from 100% to 60% in little over an hour, doing nothing but listening to music with the screen off and auto-sync etc off. I bought a replacement battery, though. And this one is working just fine. You might just be having bad battery luck, or it might be your device, I know some people have returned their Rezounds because of battery life/heat problems, and the replacement generally fixes their woes.
so what did your betterybattery stats report?
Thanks for running this test. It would be very helpful to everyone if you could pinpoint this to a battery difference and I'm waiting to hear your results after the battery swap.
What helped my battery life most was to uncheck the box under "settings -> applications -> start automatically" It has something to do with a task manager. It probably wouldn't explain why your wife's phone does better but it could help both of you get better battery life.
bik- The betterbatterystats file is attached. I see a lot of activity on her phone but very little for mine. The only thing that stands out to me is I have alarmmanager waking my phone for 10 mins and she had it waking hers for only 5 mins. I am not sure exactly what alarmmanager is though.
HTGaming- Thank you for the suggestion but I have already done that as well. I think I have literally turned off everything possible on this phone because it is driving me nuts to burn through battery like this. My OG droid used to us 30% in a day max and now I burn through that in an hour if I am using the phone for anything at all. Pretty much the only thing I had running on the phone lastnight was 4g service which her phone also had.
Another thing you can do to compare the two phones is to install battery monitor widget to see what the drain is on the phones. I used to have decent battery life but ever since the update, it's been worse. The one thing I noticed is that now my phone draws more current when sleeping than it used to. The drain is consistently close to 300ma, whereas before it would be less than 200ma when sleeping.
You have to have the widget on for the monitoring to be active unless you change the preferences.
I swapped the battery's lastnight and here's the results. Hers is still clearly better than mine even though betterbatterystats shows way more activity on her phone again.
Battery % left : 84% (mine) vs 90% (hers)
Data used overnight: 279kb (mine) vs 498kb (hers)
Time awake: 5min 32sec (mine) vs 12 min 8sec (hers)
Time in Deep Sleep: 7hr 58mins (mine) vs 7hr 59min (hers)
Someone posted that they saw different PRIs on phones even after the OTA. Do your two phones have the same PRIs?
damnn thats just weird
Im starting to think that some Rezound batches are differently tweaked than others. My first Rezound had great battery, I would stream music for 5-6 hours on 4G and would still be above 60%. My last two however were completely horrible, on 4-5 hours standby it losses closed to 20% with lil to no use. Same settings/apps as my first Rez. I regret returning my first Rezound, it truly was the perfect phone.
There really has to be a reason why some come with a 3.8 V bat. opposed to a 3.7 V. HTC wouldn't just send out two different types of battery for no reason.
You are missing 1 key info in your analysis, which people always seem to leave out when talking about battery life. The screen on time. I see in in the graphs but it's hard to tell the exact number. Because of the 720p screen on our phones, that makes a big difference. When my screen is on, the phone uses up at least 600 ma/hr. That is conservative, usually it is more like 700-800. We'll assume 600 for now. That's 10 ma/minute. Based on the stock battery, that is 0.6% per minute. So having a difference in screen on time of 10 minutes will give you 6% difference in battery life.
i am also unable to go for even most of a day on one battery charge - and i have 3 extra batteries that were from ebay that dont work even that long...
i do notice it when the screen is on the most - yest i used the gps for an hour and a hlaf without plugging the phone in and my battery lasted about 3 hours after that and died....
very bad....
very interested to see if its the phone or not - great work...
I'll try to answer a couple of questions in here. I got very frustrated yesterday so I flashed an ICS rom to see how my phone did with it. It is equally as bad. This morning, I got into work with 97% life, checked my email for about 2 mins and was already down to 90%. I have the screen display set to 30% brightness too. I am amazed that people can used 2-3 hours of display and still have 70% battery after 10 hours. My screen at 30% brightness probably drains 2% per minute. I think tonight I am going to try to install one of the stock RUU's just to check and see if the OTA upgrade possibly didn't install itself correctly.
HTGaming - I will check the PRI's tonight.
Bluesnake - Both phones were purchased the same day so I would guess they are from similar if not the same batch. Both have 3.7 batteries. Infact when I first got my phone, I could have display on auto, sync everything every half hour, use the screen for random browsing throughout the day and still go home with over 70% left. Somewhere along the line my phone has developed some sort of draining problem though and no amounts of clean installs seem to fix it.
b5fan - Both phones were off the entire night. I think screen usage was maybe 10 seconds for both of them. They literally just sat there on the nightstand while we slept and mine drained 2x faster with nothing running while hers ran facebook, email etc.
I checked the PRI on both phones and they are the same. I re-ran the stock RUU tonight so I will see if that makes any difference. I highly doubt it will but I am running out of ideas.
I guess I was thrown by the screen shots. They both show some noticeable screen time.
the only other thing I could think to check is the email type, push versus pull, and the frequency.

The screen time was probably just from me getting all of the data off in the morning like the screenshots and battery stats. Her email was on push and my email was set to not sync at all. Basically she had a fully functional phone and mine was set to do nothing which is why the battery drain is so hard to explain.
I did run the stock RUU image lastnight for my phone. I put it in airplane mode overnight and it was at 97% when I got up which is a huge improvement. I took it off airplane mode at 6am today and when I got to work at 7am, it was down to 90% so I guess I am in wait and see mode now. I have no email accounts/facebook accounts/ or anything else setup right now. It is only the stock image so there should be nothing draining battery today.
I can confirm the phone is no better now after the clean RUU install. Let it sit overnight and it was down to 80% this morning. I did not even setup any email accounts or download any apps yet. This is just the stock image from verizon.
Hello everyone, I'm using Motorola Atrix with Epinter CM10 4.1 ROM for last 2 months, I was very happy with battery life. Phone wasn't getting hot and with normal usage, even with 3G on (in my country only options are 2G and 3G), I could get %40 of battery end of the day. But for no reason, phone has started to get hot (only 2G on) and drains battery really quickly for last 1 week. I can't even get %5 battery left from morning to evening now. I didn't change anything, only installed Adobe Flash 11.1, then I deleted it but nothing has changed. Phone gets into deep sleep no problem with that, no background apps. I did a virus scan both on phone and from computer, both came out clean. I reinstalled rom. Nothing. I'm gonna crash my phone against wall it's really annoying. I think I'm gonna do factory wipe and reinstall rom again.
Any ideas? Thanks in advance.
Do you leave wifi switched on at all times?
I use MIUI on my Atrix (partially based on epinter's work, I believe? Correct me if I'm wrong), but I have found that the phone suddenly starts staying awake for no apparent reason a while (often a couple of days) after I've left wifi switched on. This obviously causes bad battery drain. I can usually get the phone to sleep again by rebooting with wifi switched off (I think) and a battery pull is invariably required.
I now just switch on wifi when I have large files to download then turn it off straight afterwards.
Not sure if it is the same issue or not, but Better Battery Stats (which can be downloaded on xda) indicated the Rilj process was stopping the phone from sleeping when this problem occurred. It is worth trying this app to see if it gives any indication what is causing your battery drain.

No I switch between mobile data and wifi. Thank you for your suggestions and opinions but I really don't think my problem is about sleep. It started to get hot and drain when I actually use the phone. For example, I was checking Twitter for 10 min. with 3G and battery was dropping %1. Now it drops %5 with 2G on and gets really hot like 35-37 Celsius degree. I'm using Watchdog to oversee processes and nothing is working without my knowledge on background.
Hi,
I have the same problem on the nottachtrix roms since the last 2 weeks, I tried switching to epinter cm10 with no luck. Ordered a new battery to check if the battery is dead or if the atrix is faulty
if you find a fix, please post it here

install gsam battery monitor to see your phone's awake time. this drain happens to me also when i listen to music or take a photo. something with mediaserver keeps the phone awake and then only thing to do is kill mediaserver or a reboot.
Regardless of which other apps you are using to monitor app and process usage, I'd recommend trying Better Battery Stats as this is much more detailed and low-level than other apps I've encountered.
It's a free download for xda members:

Little update.
I turned back to factory settings, then did a full wipe, cache wipe, dalvik wipe. I was so annoyed I even did system wipe manually from advanced options in recovery. I reinstalled Epinter CM10 rom, got my apps back thanks to Titanium Backup. Installed GSAM (thanks to saldirai), downloaded SetCpu and chose Nvidia Tegra 2 T20/AP20H, underclocked to 912 mhz. Couldn't done any undervolting sadly, says something about governor.
Now I'm checking battery stats and temperature by GSAM, so far no complaints and better from yesterday BUT I haven't use my phone heavily yet. Temperature changes between 26-31 Celsius degrees, battery drops %1-2 percent on use -also it needs calibration- with only wifi use which is always on. I'll update this post if anything changes.
Update: I think I've found the problem. When I choose The Weather Channel widget to "use my location" phone immediately starts to get warm. Weird point is, this wasn't an issue before. Apart from that I'm playing New Star Soccer and Carmageddon for 3-4 hours with wi-fi full time on and battery drops to %30. I'm really happy about that. Normal battery temperature is about 25-32 during the day and different from before it quickly gets cold after I stop playing games. Just like before.
I am starting this thread to see how you fell about new OS and do you have significant battery life change after 8.1 update.
Mine experience is not so good, at least to say, noticable battery drain...on slight use I manage to hold about 15h on NL 920, with battery saver and disabling backgroud apps as it was on WP 8.
Tell us your experience!
My battery life is also gone for the worse. With very moderate usage it barely keeps 16-17hrs, anything else is killing the battery dead.
my battery also worse but i make hard reset and do new settings manually (not restored from backup) and battery is much better
Battery life sucks on 8.1
I used to only charge every 2 (two) days and even managed to get 3 full days now and again depending upon work, but now it needs charging every night before bed . I charged it last night and went to bed and woke up today and 75% charge remaining, so it used 25% power doing nothing but hiding in my pocket. It used to only use 1% or 2 % charge overnight but not now.
Other thing i noticed is background tasks config page is missing and now the calander once open stays as a runnning task in task switcher.
I know after a firmware update the battery needs a few charge cycles to sort itself out but i am about to start the 4th cycle now and its still seems to be sh1t

Just found background tasks again. yeehaaa

Yeehaa time ti kill some apps again and save some juice
in my lumia 920 battery life is terrible after the 8.1
ie and whatsapp are sucking my battery juice as hell
guys, you must make hard reset and you must set all settings from fresh, not use old backup settings and dont forget block unnecessary apps in background... after this battery work much longer. this worked for me...

But.... but.... I just flashed the ROM two weeks ago, I don't want to have to reload everything AGAIN!!!. That said, with most of the settings synced, I'm willing to give it a go. Will report back tomorrow.
After a few tweaks in the background settings and an empty to full recharge everything is now back to normal. Yeehaa 2 days between charges and 1%-2% drain overnight. SWEET so no need to hard reset unless you have major problems. just sort the background apps and see how it goes
Im having a nightmare after 8.1 battery drain is the least of my worries..
my phone becomes unresponsive and only a hard reset brings it back to life .
I also get the screen crash and it looks like a old tv not tuned in
but it is an early release so hopefully ms will look and fix he problems because the update is worth it
Hey, I have the same problem. But not only the battery draining, the phone heats up. And I mean REALLY heats up. I gets hotter than my Laptop. Yesterday, while videocalling on skype over WIFI, the camera went dark, and 10 seconds later the picture was green. I don't mean just a completely green picture, It still showed me, but I was green. I then ended skype, opened the camera app and it was just awfully bright. With the flash off, the lights in my room out I could still see everything through the camera, but it was corny as hell. I then had to reboot the phone and everything worked again, but still. It's quite concerning, specially considering the heat.
did you make hard reset and set phone setting without using old backup settings?
phone work much better if you setup all from fresh beginning... seems old WP8.0 settings sometimes mess up things...

In Lumia Black and older versions the "background tasks" was in applications menu.
In 8.1 preview I can't find it.
Thanks!
Find in App list Battery Saver :victory:

Well, I did reset it a few times. The first time I got it it had 8 on it, upgraded to 8.1. Then reflashed it, upgraded and used the backup. You really think it could help? If so, I may try it later today.
The skype thing frightened me the most to be honest.
I never used the 920 before the 8.1 update as I bought it on the 8.1 release day so can't compare the battery life before & after.
So far ive found the biggest hog on battery was the intermittent glance screen though proximity glance is ok but the biggest culprit was having 3 email accounts set to push receive emails. After changing to sync 2 email accounts manually & the other every hour I noticed a big improvement in battery life & its now similar to my previous Galaxy Nexus.
Worse battery life
My battery life was terrible, but after the last update it is much better and with 3-5 minutes of calls a day and HSDPA internet enabled it can last for 24 hours.
My battery life has increased significantly. With 8.0, the battery life was frankly pathetic. I couldn't even get a day out of the phone, and that's with only having 3 mail accounts and Facebook active (NFC & BT off), and only moderate use. It was bad enough that I couldn't use it as my daily phone.
After 8.1, it's a dramatic change, it easily lasts me a whole day - used it moderately today, and now 15 hours since taking it off the charger, there is still 45% battery left. I love 8.1

I agree, 8.1 has extended battery life... Not that I had any issue with it lasting the day before!

For me battery life has become alot worse after 8.1. And there's nothing I can turn off in battery saver
