How to Turn On Battery Saver Mode on Your Phone

Tap a platform to see how to turn it on.

iPhone

Go to Settings > Battery and turn on Low Power Mode, which reduces background app refresh and dims some visual effects to save power.

Android

Go to Settings > Battery and turn on Battery Saver, which limits background app activity and screen brightness to make your charge last longer.

Turning It On Automatically

You can set battery saver to switch on by itself once your remaining charge drops below a certain percentage, so you don't have to remember to enable it manually.

Why It's Useful

Turning on battery saver before a long day out without a charger stretches how long your phone lasts when you need it most.

Stretch Your Battery When You're Away From a Charger

Battery saver mode won't work miracles, but trimming background activity and screen brightness adds up over several hours, which can be the difference between your phone dying mid-afternoon and lasting until you get home.

What Battery Saver Actually Changes

Turning it on doesn't disable calls, texts, or basic functions β€” it mainly throttles background app refresh, automatic downloads, and some visual effects, so apps you're actively using still work normally, just with a bit less happening behind the scenes.

Frequently Asked Questions

Will I stop receiving messages or photos while battery saver is on?

No, core functions like calls and texts continue to work normally. Only certain background refresh and auto-download features are limited.

Can I turn on battery saver while charging?

Yes, though many phones are set to automatically turn battery saver back off once the battery reaches 100%.
