If you’re upgrading your current device to iOS 7, you will see a noticeable decrease in battery life.
If you’re looking to avoid dead batteries, here are a few settings you can tweak to keep iOS 7 from sucking your iPhone’s life.
iOS 7 lets certain apps refresh even when you’re not using them, which is both super convenient and a big problem for users who want the most out of their batteries.
For some apps, like Maps, this makes a lot of sense, but if you’ve authorized other apps (Twitter, Facebook) to track your location without actually using the in-app features that go along with it, you should turn it off. If you don’t use the apps to begin with, turning off the GPS tracking won’t do much, but if you can disable tracking for a few of your most-used apps, you could see a decent boost in battery life.
iOS 7 introduces AirDrop to the iPhone for the first time, but even if you find yourself using the handy Dropbox-style feature from time to time, you should be turning it off when you don’t need it. From here, it’s just two taps to either enable or disable AirDrop, and while you’re here, you can also disable Bluetooth and/or WiFi to help save additional battery life when you’re not using them.
