The Samsung Galaxy S III Mini that I currently have is actually handed over to me by my mother, who had used it for over a year. She used to call a lot.. And now the total call time is 637 hours. The original battery had many issues, it would immediately get switched off when the battery was at a normal level, sometimes even when the battery is at 99 percent.
This is my first ever post. I'm having nexus 4 from past 1.5 years and very inexperienced user in terms of development stuff. I dont know if my battery is gone n i should buy new one or just the processes running up. Earlier when i used to wake up after 6-7 hours of sleep i could see only 10% max battery drain. But nowadays I have never seen my mobile in 'Switched On' mode after i wake up.
