battery time just fell off

without doing anything new my battery time just droped off the face of the earth.. its down about 75%. i was getting a full day mixed use now all of a suden im getting 6-8 hours with just a few phone calls.
my awake time is at 16%
I havent done anything new that i can think of.
im using (and have been for awhile) the mugen 1800 extended battery.
trying to think what might be doing it and cant come up with anything i havnt found in the forums already.

you probably downloaded some app that is running in the background continuously. check with a task manager to see what's running, and then try uninstalling some recent apps to test it out.

thats what i was thinking but i cant find anything new running with the task manager

Could just be a bad battery? I'm having same problem, maybe worse with stock battery. I went from 100% down to 15 in like 5 hours just reading my RSS feeds every hour or so. I think I may have fried my battery using it to tether for excessively long periods.
You're not using your phone to tether are you?

Mine is way down this week too. Initially I thought it was Swype, but not so sure anymore because no other users are reporting problems.

Are you using Modaco's rom and kernel ? or any new kernel for that matter? Ever since I switched kernels my battery hasn't made it through the day.

I'm using gbhil's custom kernel and seeing BETTER battery life when used with setCPU (using ondemand setting with 'standby/sleep' profile turned on, and set to 160/480).

No I'm not.. Turned a few more newer apps off and still no good today.. I was at 5% batt left after 9 hours with about 10 minutes web browsing (not wifi) 4 or 5 text messages and about 45 minutes talk time. That's down about 90% from were I was a week ago .

I managed to narrow my problem down to the Taskiller widget. Removed the widget (still running the app full time) and all is well.

Last night I rolled back to before I used a custom Kernel. I rather battery life over speed. I need my phone to last from 6am to at the very least 7pm. I think once people get over the performance boost, we'll see a lot more posts relating to battery issues.

might be that too, i hope not as i love that keyboard. just having it installed shouldn't drain the battery, should it? im on day 2 with the custom kernel and i too noticed more battery drain. at 1pm my hero was fully charged. i only played a bit with the phone and made two short calls and it's down to 86% already at 4pm. i want to roll back but i do like the speed of the new kernel. ill see how it does tonight.

Yeah going back to regular input sucks. Swype was only some leaked beta version, we don't really have right to complain; however, I bet their end product will be much better. I just hope they'll release it as an app and not as part of custom Android phone so we can get it sooner.

figured I woud resurect this thread rather than start a new one.
yesterday I decided to RUU my phone to pull the completely stock apks out of it. after I did that I restored my backup of fresh 1.1 with gbhils kernel and now I am at 90% awake time spare parts shows that "android system" as something keeping it awake. any suggestions on what this could be? could it have something to do with restoring the back up with the kernel over stock without a wipe?

CM5 or CM6 Battery Life ?

Which provides more battery life.
Im on CM5 now and my battery dies SO FAST you can almost see it going down just watching the screen, i have the screen turned all the way down, use only 2g networks. ever tried to under-clock, when i check battery usage says system idle uses 49%
any ideas ?

Are you serious?
Better yet, don't use the phone at all, that might save the battery.
Dude with those settings its like having a 20th Century device.
Flash another ROM or something, try wiping battery stats, it has been suggested all over the forum...
Why do I even bother...when the mods see this youre a gonner anyway.

It's not so much the ROM, its the apps and widgets you have installed. Some are poorly written, some don't play nice with other apps or certain set ups.
All you can do is install a monitoring app like system panel, and remove the apps that are using alot of CPU.
That's what I have done.

listen pal what im saying is my battery doesnt last for **** since i flased CM5 so im wondering if thats to be expected with CM5 and maybe fixed in CM6. but yea ur super helping that for the sarcastic reply, next time dont bother. ooh and btw i dont have to use the phone for it to die with in like 10 hours it will be idle the entire time and it will die.
Edit : OH LOOKY (Dev)CM's2.6.34.2(NR-6.35)(v0.63_08/16)(git updated-08/16)

and thank you for your helpful reply i will look into the apps i have.
EDIT: Battery usage says system idle is nearly 50% of usage, even after i kill all the apps :[

LOL! Wow, someone's a little edgy...
It's definitely not a "CM5 issue" that would be fixed in CM6 (CM6 is still in RC, CM5 has had several stable releases!) eyegor's suggestion to wipe battery stats was probably good advice believe it or not. Charge full, power off, leave plugged in. Boot into recovery and wipe battery stats. Power down, unplug and start up, let it drain allllll the way.
Check out xda homepage even - a battery calibration post!!

Battery life is pretty variable as you can see in the numerous threads on this topic. CM's forum has one with a poll with most saying CM6 is better, but not a clear cut answer.
I used SystemPanel's monitor function to identify which app was eating battery. It worked great! My biggest offender was Weather and Toggle widget. I loved its customization but its battery gulping was just not worth it. Got rid of it and my battery life is much more consistent.
I also got a cheapie battery off eBay which helped.

Both CM5 and 6 run perfect on my phone. No battery drains.
My point was that you're in the wrong section, pal.

You also might want to watch logcat while the phone is idle or sleeping to see if there are numerous errors or warnings scrolling by when there should be very little activity.

I have a similar issue. Initially I had the rediculous drain, but as mentioned wiping battery stats from recovery fixed it for the most part. Once it says its fully charged and you turn the phone off, let it sit charging overnight. Then wipe the stats in the morning and don't charge again until the phone turns itself off. Only issue I have now is that when I've got my GPS turned on, in use or not, it kills the battery. While in use I get about 2 hours from a full battery to the phone turning itself off. Haven't figured that one out.

thus far ur method has worked ! my battery so far seems to last longer then when i first got the phone LOL
i was playing music at the loudest volume for an our just to test it and it only went down 3 percent battery life
thanks man

No worries. It freaked me out when I first flashed 5.0.8. I use my phone as an MP3 player in my truck with it plugged in to my CD players AUX Jack. Did a 5 hour road trip and only lost around 10% including a few phone calls.

Rar! Faux-mod is angry!

A battery issue that's driving me insane.

Ok, my battery(atleast I believe it's my battery) is having a serious issue, so hopefully someone will be able to help me out on this one. After flashing multiple roms and such over time now, this has never happened till now, basically whats going on is my phone will be completely charged, then ill unplug it and mess around with it for a short time then say the battery percentage is at 75% well randomly the phone will just completely shut off. When turning it back on the battery will be completely dead, or on occasion it will either be slightly the same percentage or lower, but most of the time completely dead. Ive been running the same old stock evo battery since the day the evo came out and im currently running Gruesomwolf's shooter e3d rom which ironically this all started happening the first time I flashed it. So hopefully someone can help out with this, been thinking the battery is just done for, but im not sure. So I figured i'd ask for some help and opinions on what to do haha

Sounds like the battery is done to me.

Your battery is toast.

since no one's said it, I think your battery is pining for the fjords.
Might want to clear battery stats and charge to full once while the phone is turned off, but I really think daisies are being pushed up...

Check and clean the contacts on both the battery and on the phone itself, being careful not to short the battery while cleaning it. Then, reinstall the battery and make sure theres not too much or any play where contact may be lost. If you do that and still have a problem, its definitely new battery time.

your battery might be dead but you should either try 1 of 3 things first:
1 - you can calibrate your battery
2 - Flash a new Kernel
3 - Flash a new Rom
you may find aosp roms/kernels in the link in my sig, if you are interested. hope i helped ^_^

Sounds like its toast to me as well. But you can try calibrating like others have mentioned just for sh*ts and giggles. It may or may not help.

Unplugging your battery and dropping a ton of percentage...that's normal with most evos...lack of an SBC kernel

If u clean the contacts use a qtip and 91% rubbing alcohol. Let it sit for 30 mins so the alcohol can completely evaporate. Then charge til green light with phone off, boot into recovery wipe battery stats, and cache and dalvik while ur there, reboot to phone run it completely dead recharge to green while phone is still off. Use like normal afterwards if battery is still acting up time to euthanize it and get a replacement
Edit: by 91% alcohol I mean the bottle says 91% on it not like 91% alcohol mixed with 9% water its the purest alcohol u can buy at the store

Terrible battery life

Hello everyone, i purchased my Nexus 7 and it arrived in the mail 3 days ago. And as with every other Android device ive ever owned, the batter is absolutely terrible. I get about 2hrs on screen time when browing the web and maybe playing an occasional game. Does anyone have any idea whats going on? Or have any way to help? Thanks so much

That is pretty bad. Try a factory reset. Might be something you installed.

I'd hate to do a factory reset cause I just barely got it set up but..I'll try it anyway tonight

Doing a factory reset before installing anything is becoming the gold standard.
Hope it helps you.

I get between 7-9 hours of active use. Sounds like some process is running amok on yours. I didn't factory reset when I bought it either....though I have rooted it since then, but battery life is about the same pre and post root.
You might want to consider a program to monitor battery use to see what's eating it up. Maybe do that before you factory reset it so you don't install the same thing again.

System panel is a good app to find what's using your CPU and better batterystats can help find what's keeping your phone from going to deep sleep. An easy way to see if this is the case is go into battery setting and select the first option(history details). Compare the Awake bar with the screen on bar. Those two should be nearly identical if not then you have a rogue app.

have you flashed any kernels or roms? sometimes this makes the tablet report the wrong battery stats for a bit.
did you run the battery down until it turns off and then give it a full charge? sometimes you have more juice than what is being reported. ive been stuck at 1-2% for over an hour before. Most likely its a rogue app though, system panel and better batterystats should find out what app it is. if they dont then it could be that you have a defective battery...

Been on mine continuously for 3 hrs 18 mins and at 60%. Excellent if you ask me. Next step up in battery life would be Transformer series with dock.

Quite the opposite for me; unlike every other Android device I've had (Nexus One, GS2) the battery life is excellent. I watched 720p mkv video on the train yesterday for a good 3 hours, and still had ~70% by the time I got home, from a full charge.
The battery life is excellent, as far as I'm concerned.

Don't think you needed to calibrate the battery to begin with. I usually get fine battery life without doing anything special.

Something must be causing the poor battery on your Nexus, Yesterday after my N7 was fully charged, I watched the movie Thor for 1hr and 54 minutes n and my battery only dropped to 83%.

I'm at 16 hours and 52 minutes with 3 hours and 44 minutes of on screen time, the battery is at 51%

My N7 is completely stock and has never been rooted. I also did do a couple charge cycles which didn't seem to help much. And better batterystats has AudioOut_2 at 38% (while I'm playing music) but other than that it doesn't seem to be a rogue app

Unless you listen to music for over 5 hours or streaming the songs it shouldnt use that much battery. If you can't find a wakelock with better battery stats then it might just be a bad unit.

Massive battery drain and an eternity to charge

Hi,
This past week, my G2 has had massive problems with the battery draining when I have been doing basic things like web browsing etc.... I can literally watch the battery drop %'s every few minutes... the phone also gets extrmely hot up the top of the phone around near camera, it gets to about 50 degree... and to make things even more worringly it takes all day to charge to full, instead of it charging to full in an hour or so it will barely get to 50% overnight..
Does anyone have any ideas what the hell is going on??? It's running stock EU KK ROM

I'm having the same issue. For me it seems to be triggered when I connect to bluetooth in my car. Once the battery drain is triggered it continues even after I get of the car. I've gotten in the habit of rebooting my phone every time a turn off the car. A major pain but it works until I find a better solution. I've been thinking about wipping the phone but I don't want to go through the hassle if I can avoid it.

First thing I guess would be to try a battery stats app (Gsam for instance) and have that running from a full charge to see if anything is running without your knowledge.

Not even with a separate app, did you guys take a look at the "stock" battery stats?
I had once a big battery drain that was caused by the media server.
If I helped you, please thank me

Ive currently tried every battery stats app i can get my hands on lol..... I've gone through the 50+ battery guide using titanium back up.... I've disabled startup programs.... Geez even Sonic the hedgehog Ep2 was for some reason just always doing something and i never touch it lol.... Anyway I'll keep a close eye on it but i still can't explain the long charge times.... Maybe something will come up
Yeh I checked stock battery stats, the main hog seems to be bluetooth when it's not even switched on :/

I actually *think* I found the very unlikely culprit.... Google Chrome Camera!!!!!! Someone else commented on the exact same problems as me on the Play Store... which sounds about right because I've had the charging probs about as long as I installed the app.... So I've removed it and hopefully thats fixed it

I could see the app maybe causing the drain but I think it highly unlikely it affecting charging. I still like the cable idea for your slow charge. Go find your white one the phone came with and try it =)
