For the last month my Samsung phone has had a terrible problem. The phone is completely charged and when the battery indicator goes down--literally just a sliver--the phone shuts off. After I turn it back on the battery is completely drained. It seems to happen primarily if I use any apps, but it happens every time I use them. The phone is only a year old and until now I have loved everything about it. Please tell me someone knows what the problem is.

You most likely have a faulty battery. If you still have warranty, bring it to where u got ur phone and get a replacement battery.

Hi anellah and welcome to the forums.

I was thinking along the same lines as Serdroid. How fast does your battery drain? Is there any one certain app you use when you notice this? Is there any certain app you downloaded a month ago? Next time just before it dies, go to settings > battery and see what is using the battery. Maybe even take a screenshot and post it.

I have been using Samsung GS2 for six months and recently been suffering from severe battery drain. I would get just 8-9 hours on a full charge with very light use.
Went through the Internet and searched forums and finally hit jackpot.

Here's wht I did:
1. Calibrated the battery. I let the battery drain completely and allowed the phone to automatically shut down. Then charged the battery from zero till 100 per cent.
I did it three times over a week.
The last time I did this, once my battery was 100 per cent, I removed the battery, waited for 5 minutes, reinserted it and switched on.

2. Turned location services off
Go to Settings, Location services:
Untick Google's location service
Untick GPS satellites
Untick Location and Google search
(Unless u r using Google Navigation a lot u dont need these)

Optional settings:
3. If u want to desperately save battery life...
Turn Auto Sync off:
Settings-Accounts and sync
Turn it off

4.Turn wi-fil off during sleep
Settings--wifi--Advanced (menu key) Keep wi-fi on during sleep ---Never

These steps hve worked for me, especially the first two, hope u guys will find them useful.

Thanks
