Hi all, So I got my iphone a week and a half ago and i am wondering how to make the most of the battery life. I have optimized the settings and turn off the wifi when i'm not home and haven't set it too permanently search for wifi spots. However, when I am at work i do set the phone to check my emails on a hourly basis. Now I have read that if your battery is completely dead you would need to send it to Apple and get another one for...$100. I dont know if this is still true. Also there is this video which explain how to change it yourself. My battery lasts about 3 to 4 days and i'm honestly quite satisfied with that. Now how can I get as much battery cycles as I can? Sometimes I'm like "OK i'm not gonna sync my phone because it will also charge it and it might be more valuable to charge it when the battery is really low". Am I correct to believe that if you keep charging your battery(or plugging your phone) everyday, it will weaken the overall battery life? I think I heard that to optimize your overall battery like you have to use it in full cycles. What do you think?
