I have had my samsung for approx 8 months and I havent done anything different or added any new apps in the last 3 months. I have had a sd card in since I got the phone and I have it on power saving setting since the first month. In the last few days it is starting to get really hot and not holding a charge. I charge my phone overnight and then unplug in the morning. This morning I went out for 1/2 an hour and did not use the phone and when I got home it was telling me that I had a low battery warning and that it needed to recharge. This is my only contact and I need a solution quickly as I am also a shift worker who is on call. Can anyone please help.
