[Q] Words With Friends - SGS2 Killer ?

Hey y'all, I've been seeing a strange thing on my SGS2 recently with Words With Friends: It totally kills the battery.
I just recently wiped my phone and put in VillainRom 1.1 with CF-Root kernel and charged up my phone. I then randomly checked words with friends and played a few words.

In 4 minutes and a half, it pulled 43% total battery use from a total uptime of just under 40 minutes.
Anyone else seen this happening with WwF ?

I've noticed Words with Friends taking up a lot of battery whenever I use it, so your not alone on this.

Yes i've noticed it too. it uses 100% cpu in one of the 2 cores while the game is open.

You're definitely not alone and I tried the application on both of my phones (Captivate and S II) and all I can tell you is that words with friends drains the battery like mad.
Furthermore, the app hasn't been optimized for dual core processor handsets yet (as it is the case with most apps). When developers start optimizing their apps for dual core processors we should definitely see an increase in battery life as optimized apps can utilize the two cores more efficiently.

Any fix for this yet? It's killing both mine and my wife's SgSII's, but my desire Z is fine.
Biggest priority for the wife is WwF so she's not happy about the battery usage! Lol

lol it's funny i played this with the gf yesterday and it killed my battery as well. i knew immediately it was the culprit

[Q] G2 Battery Life Issue

For the past couple of weeks ive been having issues with the battery life on my G2. I used to get 12+ hours of battery life on it but now im only getting about 7 or 8. Ive tried recalibrating the battery, clearing the dalvik cache, and changing settings on certain apps but that hasnt seemed to make a difference. Ive noticed that at the end of the day, the android system takes up a huge chunk of my battery. Any ideas?

I've had the same issues as the builds of CM have gotten higher in numbers. The ROM that's given me the longest life is the stoock Gingerbread rooted ROM. I switched back to CM because oof the Text MMS & them always being Slideshow issues as well as no ability to stoop the phone from vibrating when I'm on a call. Same issue with CM too actually.
I'm bumping this because I feel your pain.

you can fix that in call settings you know!

Are you running CM7? If you are, open up spare parts and look at the battery information under Partial Wake. See if there's something tying up the system.

There are a few things listed but I dont think its anything that would eat a whole lot of battery. Should I be looking for something in specific?

Anything that's more than a sliver is eating the battery and keeping your phone from sleeping.

I'm getting 24 plus hours on glite which is aosp also. Maybe the battery is finally giving up the ghost. They do have a finite amount if charge cycles. If nothing else has changed and all things being equal to your 12 hour charge cycles maybe you could try a different battery.

Weird battery activity

So I charge my phone all night, take it off the charger to go to work at 6am by 3pm my battery is at about 8 percent. Here is where it gets funny, if I turn the phone off then back on I have about 59%. How does that happen

Sorcery. That's how.

I'm guessing the reason your battery gets drained so quickly is because of the poor network coverage.
Could you also provide a screenshot of the apps/programs/hardware that have drained your battery? By that I mean the screen you see after hitting battery under settings.
The fact that it goes up so much after a reboot is very weird indeed. It usually happens the other way around with mine, the battery level drops about 15% for me after a reboot, which I also find weird.

I have had the same expierence with my phone as well. Dont understand it either.

I suggest you use a battery calibration app or s-off/root and install Clockwork Mod recovery to clear your battery stats and run a few cycles. Your phone doesn't know where full is and can't detect it as well as we'd like.

I think you need a battery calibration. Before i calibrated mine would drop 10-15% sometimes but now it is good. I would also add expect a small margin of error if you were using your phone heavily and it is warm/hot and you reboot. Some people report, myself included, that you might see a slight spike after your phone cools down.

[Q] possible battery issues with darkside digital warfare

I can't seem to get the battery results people are claiming. It seems like I lose 10 percent usage per hour during the day. I am starting to think I might need to replace my battery. Last night I left my phone unplugged and It drained over 25 percent with 7 hours sleep. When I installed the rom I used the wipe flag. I haven't touched a CPU controller cause it was suggested not to.
How do I find out exactly what is draining the battery so much?
I heard about battery calibration. I have read about a few techniques. I have also read that it is a placebo.
I am not sure what to do. Here are some screens. The drainage doesn't seem normal.

Battery life really depends on the user much moreso than the rom. are you constantly using gps? google location? Wifi? Facebook sync? Twitter sync? Google talk? Other im's thru social hub? max screen brightness? constantly receiving calls and texting?
All of these factors influence your battery life. its probably not the roms fault.

I am not saying its the rooms fault. I am trying to figure out what is causing the drain. I don't use social hub or the Facebook aphp. Only thing I kesync is Gmail, contacts, calander. Also, I use gtalk. I don't GPS at all.
Something is draing the battery.

Large battery Drain after newest update

So a month ago I upgraded my epic 4g touch to stock rooted most current official release, and flashed the newest clock work mod... Not sure what kernel. And anyhow, after flashing it, basically my battery dropped in more than half.. After an hour of it sitting around I drop 30%. I even have greenify keeping my apps hibernated. Since I'm use to the s3, I'm not sure what to do.. Do I just flash a new kernel or what? Yes I did search and got nothing about battery drain after flashing an update.

Try the suggestions here-http://forum.xda-developers.com/showthread.php?t=2474084

Those are all common sense and app suggestions... This isn't an issue to be fixed with an app.. It's something going on.. Maybe the kernel

Most likely an app causing wakelocks that isn't allowing your phone to sleep. Look in Settings/About Phone to see what kernel you flashed.

I believe that your power drain issues are related to mine. Sometime in the last two months I found my battery draining about twice as fast. Upon investigation i found that nlpcollector was the culprit (google location services). After turning off google location services I found that my battery life went back to normal. I understand that this isn't an ideal fix, but hopefully it is temporary and google fixes nlpcollector so it isn't doing wakelocks like crazy.
