Navigation apps are certainly handy, but they’re also pretty bad for your battery. That’s because they often use Background App Refresh, Location Services and hardware like your phone’s GPS chip to keep their data current. (This also goes for location-using ride share apps like Uber or Lyft.)
To cut down on their battery drainage, when recommend going into Location Services and setting the apps to only use your location when they’re open. Unless you have a specific reason to use a third-party app like Waze or Google Maps, it may also be worth ditching them in favor of the native Apple Maps. It’s better for battery life — and comes with some privacy bonuses, too.
