I know this question has been asked to death but I have yet to find a case like mine. I have had my S3 for a 2 years and my step mom had it for 3 years before that. It has been an awesome little phone and even with all its issues I still think it's a better phone than any replacement I could afford right now. About 3 months ago I started having trouble with my power button sticking. It eventually got so bad that I had to let the screen timeout because if I pressed the power button it would stick and get stuck in a reboot loop. This issue last a couple of weeks and eventually seemed to clear itself up. Then it started charging ridiculously slow and draining super fast, but only on Wednesdays and Thursdays. I also began having trouble with chargers at this time. I went from being able to use any charger or cable to only being able to use certain ones. If I plug others (that have previously worked fine and work fine on other devices) in it will start and stop charging. After about a month of this and being ready to toss the phone. it all got better. For the past month I have had no problems out of the phone other than being limited on what charger I can use. Now all of a sudden today we are back to the same problem. Overnight my phone only charged to 56%. By the time I got to work and hour later it was at 22%. I plugged it in to charge and at lunch it was up to 26%. I took it with me to lunch but did not use it. When I arrived back an hour later it was at 10%. It has been plugged in since then and is only now at 16%. At first I thought it was a hardware issue but hardware doesn't pick and choose when to malfunction does it? Any help would be greatly appreciated.
