Every time your phone buzzes with a notification of a new Snapchat, tweet or Instagram like, it loses a little bit of power. Keep the notification alerts to a minimum to maximize that battery life.
We know, you don’t want to miss an e-mail. But the fetch function—which is always looking for new mail and pings you with inbox updates—is a major battery drainer. Turn the function off on the weekends (at least) to extend the power while you’re out and about. – Kevin Aeh
