I wanna ask if a damaged battery can affect performance of my S3 Mini and what's the average time the phone is able to stay charged with a completely new battery. My battery time sucks (i get max 9 hours if I don't do almost anything on my SMARTphone ). So will replacing my battery solve some of the lag on my device and how many hours should I expect from the newly purchased battery with average usage (max 2 hours music, a few phone calls, max 1 hour gaming-small games mainly and sometimes web surfing). Thanks to anyone that replies. Cheers
EDIT : My battery also heats up to 36-39 degrees celsius while just playing Soccer Stars while listening to music from PowerAmp. I think this isn't even close to normal. If a new battery solves all these issues, I'm willing to buy the best one (presumably original by Samsung)!
EDIT 2 : My phone charges from 1% to 50% for about 30 mins o.O
