hI,I just got a Samsung Galaxy S5 few weeks ago, and I find the battery life of the phone is good but I have had to recharge it each night because my heavy usage. I have read some articles on saving battery life, like switching off GPS, WiFi and apps when not using, lowering screen brightness and I even waiting for a slim extended battery from mpj. I noticed that the phone was getting hot when playing game, will this damage the battery? How do you get more battery life?
