(Q) battery drain

OK, my wife has had this phone since last September and it has just recently been suffering from some very unusual battery drain. Tonight I placed a fully charged battery in it at 9:30 pm killed all the non essential apps via menu / settings / running services. And by 11:00 it was already at 50%. What could be causing this issue? It is fully stocked and not rooted. Thanks for the help

Possibly a app that u downloaded is waking it up or an update u did recently.

I'm having similar battery drain problems with my SGS2. My phone shuts down, like empty battery power, when I'm online for a few minutes or playing a game when in fact the battery still has more than 50% stored power. This started happening a few weeks ago. I didn't download or update any app before I noticed this "phenomenon".
Anyone has an idea what could be causing this battery drain? How can I resolve this?

Thee have been a few times where my battery drained overnight where it only usually goes down like 5-6%. Both times I run found out there was either a tower down nearby or they were doing work. Check an app like badass battery moniter, it gives you a rundown of apps and modem drain.

Download system panel and see what programs are eating up CPU and using data. Also consider Wi-Fi and data toggles they save a ton of battery and turning off background data. If your still have major drain issues hope got insurance...bring it down and get a new battery.

What issues do you have after Bell update

Well I updated because I was thinking it was going to save some battery life, maybe a bit fast (Lets be honest, I may of had a little chubby thinking it was jelly bean, blah so disappointed)
Anyhoo the 2 days that I have had the update Iv noticed worse battery life and for the first little bit it was LAAAGGYY. I called 2 of my other buddies who advised that they did not notice anything laggy but did notice battery life was way worse.
Anyone else?

Brutal battery life over here.

No complaints thus far. All bloatware removed and unnecessary widgets frozen using TB.

I guess I shoulda been more specific. So before the update I was getting a full 13+ hours with normal use. Now I will be lucky to get 8 hours. I actually had to buy a usb charger...I never owned one before this.
I could try rooting, removing and stopping some programs to see if that helps, it's just weird how I lost that much batt. I wonder what changed.

use can freeze most apps without root/TB in the app manager in settings. Just click the app force stop and freeze. Some may need to have the update uninstalled before freeze options shows up.

Yeah, my battery life is much worse now, need to charge everyday rather than every 1.5 days..
I do notice lag as well. Need to clear my recent apps much more frequently.
Seriously, for me, the only advantage for updating was enabling the Allshare Cast option..

[Q] Sudden drop in Note II's battery life

I have a Note II that is around three months old. The battery would last around 1.5 days with normal usage.
Then, about a week ago, I noticed that it was not even lasting a day. Often 'media' uses more battery than the screen, which I have never seen before.
Last night, I fully charged it to 100%. I woke up 7 hours later and took the screenshot below - 49%! 51% used in 7 hours standby time. This cannot be right? Surely? I have noticed something going on with my SD card, where when I unlock the phone, it "prepares" the SD card. I had not seen this before.
Also, a strange phenomenon occurs where when I delete an app, it leaves a hole/gap in it's folder. (see screenshot 2). I cannot get rid of it. Any ideas?

Having the same problem. Mine used to get almost 2 days and after the latest OTA update "Media" seems to be using a ton of power. It seems to be related to scanning the media files. When I try to force stop the app, it just restarts itself. I thought maybe it was a bad SD card, so I tried a fresh one, but the problem is still there. Any ideas if this was introduced in the update and whether or not we can stop the process. I am not rooted on stock ROM.

Download media scan root from play store. It will disable media scan and you can re enable it with just a click If you have new media files. But root is required for this app.
Alternatively if you do not have root. Try format the sd card. It might solve the problem a while but not sure why it comes back again. It s a known issue for jellybean

I have not, no. I am not rooted and personally do not want to be. It sounds like this is a fairly widespread issue. I will talk to Samsung and hopefully get a replacement or refund. No way that I paid $1000 for a phone that only lasts 12 hours.
Thanks for your help.

Are you also on 4.1.2 like bwallis?

Nope, still on 4.1.1.
Also, Google+ is now using a fair amount of battery too, usually around 10%. Strange when I don't actually use G+...

I tried a new freshly formatted SD card and today I am at 70% after about 12 hours. This is what I was getting before the upgrade. Will keep everyone posted if it happens again. Before the new card I also noticed the system was unmounting and remounting the card frequently. I am sure this is what was causing the rescans. It was only 2 months old so perhaps the card was bad.

there is something weird going on with the battery after updating to .283 . i tried to investigate this with the help of wakelock detector and apperars myxperia and update center are eating up lot of battery. froze them and so far so good.

Froze those as well and still massive battery drain. Checked the battery usage and it seems the OS is the culprit. Any suggestions?

if you flash rom for several item ..........you can get a battery calibration app and calibrate your battery.

Downloaded that app and ran it. Still testing. Will keep the thread updated with any abnormalities.

haha same hir , I thought my battery is the problem, seem im not the only one facing this problem, hope there is a bug fix for 4.4.4 or maybe we should wait for android L

Download BetterBatteryStats (there's a free version on XDA)
You can get a decent amount of information regarding wakelocks, partial wakelocks, alarms, etc..
There's also the possibility that your battery could by dying, if you want to know for sure either use something like BBS or reflash/reset to factory.
