Not charging but Draining (samsung galaxy s3)

[solmaz]

I have a Samsung Galaxy S3 I bought it in feb or march of 2013 and recently my phone has been acting very strange. Every time I charge it I can not use it or it will drain , it takes about the whole night or day to charge but before it would only take 1hr-2hrs. As well if i leave it to charge and once its reached a 100% and I dont take it out for awhile it will drain not knowing since its telling me 100% so when i do take it out tells me 0% , 5% , 10% or 15% please plug in charger. I've tried putting it on flight mode to make it charge quicker but once i take it out it tells me 5% and ive tried turning my phone of then charging but sometimes my phone will just stop charging all in all . I'm not suire whats wrong since i have bought a new charger for it in april and it was working fine . I think its the battery itself that needs to be changed since I have now gone through 3 chargers . Please someone help me

Welcome to the forums.
I am inclined to agree that the battery may need to be replaced.

Well, having a spare isn't a bad idea either.

I have this same problem. Got me 2 2100mah anker batteries and a charger for $21. Worked well. Always had a 100% on my other battery when one died. Had a 3 battery rotation for about a year now. About 2 months ago. One anker battery went out. About a couple weeks ago my other battery went out too. So I'm back to one now. But I have more coming in again. It's efficient, cheaper, and better than charging the phone for multiple hours.
