Battery problems

Hi, my s2 is using villainrom 1.4 as an attempt to improve battery life. At the moment i am on 50% battery after 4 hours and a bit with screen on time at 2 hours. Even with moderate usage i hav never gotten over 12 hours...
Could someone give me tips how to get my battery to at least a day, desperate for help. I have auto sync off and use a mixture of wiki and 3g.
I will post the screenshots of battery later as i dont have enough posts yet.
Thanks

What apps u have installed?
Go to the built in battery monitor and check for wakelocks (when the screen is off, but the device is awake)

as what BSAKSOUK said, what apps do you have installed?
Try to uninstall all apps you have installed and see if you get some improvements, then install one, test again.
I found that NetCounter kicked in on my SGII and the phone never went to sleep, just screen off but it was awake and drained the battery in 12h
//Mike

I will try and post the sreenshots soon. It seems that awake and screen on is largely related. I may have to factory reset and see how the battery fairs then.
I did a *#1234# and saw my csc is unknown? Do u think there is somethin wrong with my modem? It seem when wifi is on it always drains the battery alot faster.
Ia there any app to monitor how much drain apps cause? Thanks guys

since you say you had the screen on for 2 hours, your battery seems correct. other people on this forum are claiming they get 4 hours of screen on time from a full charge. so if you had 2 hours and 50%, that seems right in line with proper results.

I am in WAKELOCK HELL

I'll start by saying that the attached pictures say it all folks.
I'm simply at a complete loss as to how my phone can be so awake ALL the time.
If anybody could give me ANY insight as to why it might be the case, I'd REALLY appreciate it.
Also, I can post my alarmdump.txt if anybody wants to see it.
Again, any and ALL help would be greatly appreciated. Feel free to ask me for any more info that might be of use in diagnosing the problem.

That NYC map app seems to be the culprit. As well as the Google Search widget, for some reason.
Uninstall the app, remove the widget, reboot and see if it's much better

Phones with insomnia... now I've seen it all.

lol bro well only about 30 minutes of that time the screen was on and I was doing stuff.
Thanks for the insights so far bros.
I'll say that I actually DO NOT have the google search widget. In fact, the only widgets I have are a watchdog widget and SwitchPro lockscreen button widget.
I'll keep investigating.
Thank you guys for the quick responses.

Well I've frozen the default ADW launcher that CM7 comes with. I'm pretty sure I took off all homescreen icons and widgets before I switched the default to Zeam.
Does anybody know if freezing the Modem Fastdormancy element in Titanium Backup would cause any problems?
Please help me fellas.
I'M DYING HERE.

im also curious about modem fastdormancy... i froze it because it was a wakelock culprit, but am getting really fast battery drain as well. not sure exactly what modem fastdormancy does tho

http://groups.google.com/group/android-platform/browse_thread/thread/9cb9c3e94da63110?pli=1
So basically, Modem Fast Dormancy = do not freeze. In my understanding, it has to do with the radio and disabling it when not in use, or something to that affect. I haven't studied it, but that's a quick 10 second synopsis from reading that article. I would stay away from disabling it.

Right on. And thanks for the info.
When I froze ADW I also UNfroze Fastdormancy, and then rebooted, so hopefully that'll help.
What about the wakelocks for Event Log Services?
Does anybody know if there's a way to find out exactly what that is, and if there's anything I can do about it?
Thanks for the input so far guys I REALLY appreciate, and little by little I think things are working out.

You're showing 27 hours there..................many people struggle to get 1/2 of that. I am one of the few who gets 28-30 hrs from full charge with moderate usage. I think it's fair to say you have fairly decent battery life, even with only low usage. I wouldn't complain too much.................just keep trying to make it better!

The thing is, he might have good battery life compared to others but his screen was barely on, he shouldn't be having all those wake locks. I have a similar amount too. If we could get this settled our 1 day battery life might turn into 2 days which would be amazing. I'm sure many people's phones are like this.

Yup bro this is exactly it.
It might be good battery life- but I'm not using my phone at all.
After unfreezing Modem Fastdormancy I've definitely got less unexplained blue in the "awake" time graph. I also froze ADW and that seemed to help.
Thing is, there is still lot of mysterious chunks when my phone is awake.
BetterBatteryStats says Alarm Manager and Event Log services are to blame (top two- represent a substantial percentage of the partial wakelocks and thus time awake).
I'm about to terminal emulator dumpsys my alarmdump.txt, but is there a similar solution for Event Log Services that will allow me to see EXACTLY what's putting it at the top? Only clue it gives is that it's apparently "Google Services."
Past that I've got no clue what it's pointing to.
If I get the Event Log Services fixed, I'd venture to say that would solve a LOT of problems for me.
Thank you guys for everything so far. You laid out some really good and interesting ideas- ones that I definitely wouldn't have thought of.
I'm very, very appreciative, and if it's not too much trouble, bros, KEEP IT COMING!
Ultimately, I want OTHERS to be able to reference this thread in their quest for a better Atrix, and maybe even a better android phone in general!

Quick question bros:
If I get my alarm manager dump, will that have any or all of the things contributing to the Event Log Services wakelock?
Like I've been saying, it looks like all I need to solve this is some breakdown of the Event Log Services to see what's putting it at the top.

I honestly always had battery issues with cm7 keeping the phone awake. I switched back to Alien ROM an now my battery life is back to normal, around 42hours. I also saw great improvement when I uninstalled Watchdog while I was on cm7 and so thus I have never reinstalled it again.

Well,
Due to this post I checked my Atrix and saw that it wont go to sleep as well, and stay practically always awake. I started using AntTek App manager to freeze some apps that worked all the time (mainly Facebook and an israeli VOD app) and the phone started to go in sleep. I dont know how it will affect the battery life (which is about 16 hours from 100% to ~5%, with data always open), but I will test it for now and report once I have some news...
BTW Im running CM7-Ba2tF, with faux123 enhanced 1.0 Ghz Kernel, and UV.

Torch widget draining battery really fast.

Hello! I was wondering why suddenly my Android OS was at 70-90% when it was below 50% when i got the phone in first place. I then started thinking what could cause the drain and then i remembered someone saying that the torch needs a lot of permissions, so i thought that was it, and yes that was causing the drain. So all i wanna say is not to use the torch widget because it apparently likes eating your battery... My battery goes about like 10% in 30min not using the phone at all with the torch widget, but if i remove it from the homescreen, it goes only like 2-5% in a hour. I hope this helps people struggling with battery problems. Please use the thank you button if this helped you.

I have noticed some odd behavior from that widget, such as it becoming unresponsive. Although I did find it handy I am taking it off immediately.
Know of any alternatives to try out?

Yeah i experienced the unresponsiveness too some times. If you want an alternative, you should look for them in the Android market. Theres heaps of them. I cant link any yet because im on my phone. When i get to a computer i will.
EDIT: This is a really good alternative i think https://market.android.com/details?...sMSwxLG51bGwsImNvbS5kZXZ1bmkuZmxhc2hsaWdodCJd

Anyone can recommend a good flashlight app which allows to adjust the brightness of the LED flash, just like the widget does? Thanks.

Hmm SanQ, I was thinking about what you said here and tried removing the battery widget and see if it was true. And hey, the battery life does improve! Looks like the widget got some serious problem. So many permission accesses!

Good to see that my tip is working for you guys.

Is the torch widget a stock widget?

Yes it is on KL7 and up i think.
Sent from my GT-N7000 using xda premium

Today I went from 70% battery to 20% in under 3 hours of mostly idle usage after using the widget. The strange thing is that yesterday I used it, too, and I had no adverse effects. So... sooooo strange. Hello new app!

yeah... Mine is about 3 months old.. I got it from technotradinghouse in the US..local in Missouri..
Mine never did have a torch widjet..
Still doesnt..
what gives???
I had to d/l mini flashlite from the market.

Same here. Mine is only 10 days old (on Vodafone UK, stock 2.3.6, KK9) and I don't have a torch widget.
I'm using one called "Tiny Flashlight + LED" and it's great.
Also, people are saying that with the torch widget removed their battery is only using 2-5% per hour when idle. I don't get it... that's a lot isn't it?
Are custom ROMs really power hungry or something? I'm on the stock ROM and it uses about 0.5% per hour when idle for me.

Ridiculous battery drain on standby

It seems that the battery drain on my newest N7 (RMA'd first one) is waay worse than on the other, I'll attach some screen shots of what I mean.. it may be just the WiFi is using a lot more than the other's :S I left it 4 hours alone with WiFi and the battery drained 20+ % which even with WiFi on seems excessive does it not? Is it possible I got one with a faulty WiFi radio? I will be testing tomorrow (or maybe tonight) to see battery drain with WiFi turned off to compare, because it also seemed to drain fast when I was just out and about with WiFi off :/ worried I have bad battery, deep sleep isn't working right (it is going into deep sleep or at least thinks it is from looking at cpuspy), or faulty WiFi... or just too early to judge XD has anyone noticed battery improve over time ? I forget if I did was a month ago I got the original
BTW first screen shot was taken pretty much right as I was leaving for work, so you can compare the battery drain there..

I doubt it's a bad wifi radio, its probably an app that is syncing like crazy in the background.

I'm currently watching the MediaServer app use a disproportionate amount of battery (14% and rising). I deleted a number of images which must of kicked in the scanner which must be very inefficient.
I also noticed my N7 become very slow at the same time.
Possibly you downloaded a large amount of images/music/etc before putting your device to sleep...

I really wish I could figure out why maps keeps starting a process.. can you check to see how many instances of maps there are ? In particular one running Prefetcherservice.. as for the other comment, media server is sitting at 6%, android is at 14%, and screen at 67%.. though I did copy a bunch of songs and pictures over after the RMA, is there a way to fix these or should I delete them to see if it gets better ?

Sigh, I might just have a bad battery, or preferably poorly calibrated, since another hour of use, just browsing and such, and I'm down 20% more -_- hope I don't have to RMA again

Bahaha good one I dunno, the problem is that this is literally my fourth N7 since the other three allll suffered from major screen lifting, so maybe I am looking for something wrong just so i can make sure it's perfect... Though I do think the battery life is pretty weak, I think I may have figured SOMETHING out, the only difference between this and my original is that my original had a huge section of the map of my area downloaded, and since I did that maps hasn't started any additional processes.. so good sign ? maybe ? haha

Yeah this might be a good time to stop looking for trouble and just enjoy the tablet for a while. I drop mine on the charger in the morning and don't ever really think about the battery other than that. Whatever the battery stats say now they won't say in a week and they won't say after you flash to a different ROM. If you have wifi on apps will sync and the tablet will loose it's charge. I'm never far enough away from an outlet to make it much of a concern. So maybe just take a breather, install the Angry Birds and have some fun for a bit. Eventually we'll have ROM's and kernels that make this thing sip electricity but for now I get the few hours a day I need out of it on one charge so I'm set.

You think the battery life will get much better than what it is? My only other android experience is my HTC Desire Z which has a horrible battery as it is so it didn't improve much at all with custom roms
Speaking of improved life through ROMs and kernels, have you noticed any kernel providing particularly better battery life ? I'm on trinity right now, no voltage changing, but underclocked to 1.1 ghz from 1.3

Factory reset, see if the problem continues. That's the only way decide if it's a HW problem.
And my N7 uses effectively 0% battery in standby, it was off the charger yesterday for 6 hours and when I started playing around it was still at 99%. I turn off wifi on screen off, however.

Use http://forum.xda-developers.com/showthread.php?t=1179809 to find out what's waking up your phone, the apk is in the second post. Install, charge it up, unplug, leave for 4 hours idle then look at partial wakelocks and alarms.
I saved quite a bit of standby time by disabling location services and Facebook.

If your not using nfc that could save battery?

So it seems like partial wakelock is mostly audioout_2 which i assume comes from me playing a game with music amongst other things?
Alarms says com.google.android.googlequicksearchbox has 50 wakeups, and maps has 38 :S why does maps keep trying to kill me?! and what is the googlequicksearchbox doing waking the tablet up...

Wlan_Rx_wake seems to be the culprit of semi bad battery. Is there a way to prevent the tablet from waking up all the time? Maybe just unsync or turn off WiFi instead?

When my battery drain was bad I had something like 250+ wakeups from maps under the alarms section in only a few hours off the charger and Maps was showing up as the most common reason for partial wakelocks.
I think AudioOut_2 is normal - Im not sure what it does though. Im now at 8+ hours of standby with 99% battery. Under alarms im showing 138 Maps wakeups and 76 from google quick search box. My drain is all gone now though so i assume this is within normal range. The better battery stats thread and a few other threads on XDA have detailed descriptions of the different battery draining wakelocks and possible remedies. Not all wakelocks are bad though.

Battery Life is absolutely horrible

Ive been using an iphone 5 and Optimus G Pro for the past 8 months waiting for the new androids to come out this fall and I am quite disappointed. I have the ATT version, i have wifi, gps, bluetooth all off, never had to do that on the iphone. I close out all the apps and clear the ram, and I went through 30% overnight while I was sleeping. My Optimus G Pro was far better on battery and that seems kinda backwards?
Is there like a break in period or something, what is the deal here

You have to figure out what application is causing the "wake lock"
What a wake lock is; Its something running in the background that is not letting the phone "sleep" or otherwise go idle. Meaning your phone is running full speed ahead while you are sleeping.
It could be all sorts of things causing a wake-lock. I had one guy on my ROM have a wakelock because his internet connection was so poor the phone just kept searching and he was draining about what you are draining everynight.
Another thing I would look at are your location settings, not just GPS. The new Google settings Icon has a bunch of crap that it syncs and tracks you via all sorts of stuff. Go in there and make sure nothing is turned on you dont need...
And lastly, like the other guy said, check for a battery stat app. They can show you what app is not sleeping or why your phone is not sleeping like it should.

Facebook is a notorious offender. With refresh off I would get over 140 wakelocks in a 7 hour period.

mine is way better now, after being off the charger for 3 hours I'm at 94% where as yesterday I was probably at like 70% at this point.

Don't forget most android handsets need a 72 hour battery calibration window before you will see a more even battery level. After 72 hours your phone should have a good batch of data to help gauge its power levels.

Battery is fantastic on this phone. Coming from an X and Note 2.

I'm still on my 2nd full charge but notice once the phone huta around 60% the percentage drop starts to slow down, I figure this is just calibration getting dialed in and so far I'm very happy with battery life.

fd toggle
Hi there, I am not sure if this is the reason but I used to have Fast dormancy toggle apk on my old lgog to prevent the phone from complete discharge even though I was not actively using the devicd. I installed the fd toggle here,too and I can honestly say that if I am charged 100 % at about midnight, I have the same 100 at about 6:30 when I get up. Of course, no data,no sync,no wifi and no active use of any kind during that time. I do not know if the app is the key but the result is pretty impressive. I have the korean version F320K.

I was using the Snapdragon Battery app on my DNA. Never sure if it did anything. Is it worth using on the G2 as well? Love the phone! Less gimmicky than the S4 and more interesting than the Maxx.

You have to figure out what application is causing the "wake lock"
What a wake lock is; Its something running in the background that is not letting the phone "sleep" or otherwise go idle. Meaning your phone is running full speed ahead while you are sleeping.
It could be all sorts of things causing a wake-lock. I had one guy on my ROM have a wakelock because his internet connection was so poor the phone just kept searching and he was draining about what you are draining everynight.
Another thing I would look at are your location settings, not just GPS. The new Google settings Icon has a bunch of crap that it syncs and tracks you via all sorts of stuff. Go in there and make sure nothing is turned on you dont need...
And lastly, like the other guy said, check for a battery stat app. They can show you what app is not sleeping or why your phone is not sleeping like it should.

This is dumb. My G2 was at 100% battery for 3 hours! You either have a lemon or your cell reception is poor where you are. The battery life is not horrible.

Yeah, I'm with the rest. I'm coming from a MAXX HD (insane battery) and the battery optimization on the G2 is far superior (albeit smaller battery).

Bought the phone over 24 hours ago and I am still on the charge from the box. Its running great for me with LTE on.
