Got a long journey ahead? Avoid being stuck with a dead device by prolonging your tablet’s battery life: Go to your device settings and tap “Battery.” If you’re on a Samsung device, you can then toggle on “Power saving” (or just swipe down twice from the top of the screen to open the Quick Panel, then tap “Power saving” ). For Pixels, tap “Battery Saver,” then toggle on “Use Battery Saver” and select from the options below.
You can also preserve battery power by turning off your Wi-Fi, Bluetooth, or data via the Quick Panel; tap the airplane button to activate flight mode and turn off all three.
