The “Wi-Fi only” setting is a prudent one, especially for those with cellular data caps, and it’ll also spare your battery from grinding that much harder to upload hefty images over a 3G or LTE connection.
But unless you’re dead-set on backing up your snapshots the very moment you connect to Wi-Fi, there’s an even more power-conscious setting for Google Photos’ auto-backup feature.
Open the app, tap the menu button in the top-left side of the screen, tap Settings > Back up & sync, then enable the “While charging only” setting.
Pick a static wallpaper image
I’m a sucker for “live” wallpaper—that is, animated wallpaper images that pulse, shimmy, and otherwise dance across your home and/or lock screen.
Unfortunately, those eye-popping live wallpaper images put additional—and unnecessary—strain on your handset’s already maxed-out battery.
Tap Settings > Display > Wallpaper, and pick a static background image instead. Boring, yes, but your phone’s battery will thank you.
