Hello! I was wondering what everyone's views are on how to best extend battery health and life. I have an iPhone 4 and I would like to keep using it for as long as possible, without having to plug it every night hoping it will make it till the end of the next day. Obviously, all depends on the way you (want to be able to) use your phone. My strategy to extend battery life: disable bluetooth when possible, indexing and push/auto-fetching emails. My tactic to battery health: let the iPhone reach 0% as often as possible, and then try to charge it to 100% as often as possible. Please share your ideas!
