The Low Power Mode setting on your iPhone 7 is one of the most useful features on the device. If you find that you are often running out of battery charge before the day is over, or if you know that you aren’t going to be able to charge your device for a while, then using Low Power Mode can help make your remaining battery charge last a bit longer. Low Power Mode also pauses Background App Refresh, which you can turn off separately in Settings.
You may already be familiar with how to enable Low Power Mode by going to Settings > Battery, but there is an even faster way to do it. Our guide below will show you how to add a Low Power Mode button to the Control Center so that you simply need to swipe up from the bottom of your screen and tap a button to put your iPhone in Low Power Mode.

How to Add a Low Power Mode Shortcut to the Control Center on an iPhone 7
The steps in this article were performed on an iPhone 7 Plus in iOS 12.2. Note that there are a lot of other shortcuts on the Control center menu that you can also add if you’ve been looking for some other ways to perform certain tasks more quickly.

Step 3: Touch the Customize Controls button.

If Low Power Mode doesn’t help
- The battery icon stays yellow after charging. Low Power Mode turns off by itself once the battery reaches 80 percent while charging. You can turn it off sooner in Control Center.
- Email or apps don’t update. That’s expected. Low Power Mode pauses mail fetch, background app refresh, and some automatic downloads until you turn it off.
- The battery still drains fast. Check Settings > Battery to see which apps use the most. An older battery may need replacing. Look at Battery Health under the same menu.
Frequently asked questions
Is it bad to leave Low Power Mode on all the time?
No. It won’t harm the battery. Your iPhone just does less in the background, so some apps may update less often.
Can I ask Siri to turn it on?
Yes. Say “Turn on Low Power Mode,” and Siri switches it on without opening Settings.
How much longer does the battery last?
It depends on how you use the phone, but Low Power Mode usually adds a few extra hours. It helps most when the battery is already low and you can’t charge soon.
