Smartphone Battery Smartphones are pocket-sized computer that can do almost every whim. But it will be futile if it runs out of power. It would be easy if you have extra battery but removable batteries becoming more and more rare, you've got to take good care of the one you got. Good thing, today's lithium-ion can keep powering your smartphones keep kicking if you follow a few simple rules. 1.) Don't use up all your battery life playing games and walking around with Wi-Fi and GPS enabled when you're not using either. 2.) So if you're really particular about optimizing your battery's life, you should try to go from around 40 percent to around 80 percent in one go, and then back down whenever possible. A bunch of tiny charges throughout the day is your second best bet, and going from zero to 100 and then 100 to zero on a regular basis will put the most strain on your lithium-ion battery. 3.) Keep it cool. Heat is lithium-ion battery's worse enemy than sub-optimal charging. Smartphone's battery will degrade much, much faster when it's hot, regardless of whether it's being used or just sitting around doing nothing. 4.)No to wireless charging. It is very convenient if your phone can do wireless charging. However wireless chargers generate a fair bit of waste heat. It may be little less convenient, but standard plug-in charging is going to keep your battery in better shape. It's easy to keep your battery reasonably healthy just by avoiding particularly terrible torture like letting your phone discharge from full to zero almost every day, or leaving it in a hot places all the time. Try to do those tips, after all we love our smartphones and we want to keep it as long as it takes.
