How to enable Low Power Mode on your iPhone or iPad and what happens when you do so

In this tutorial, we’ll share how to toggle Low Power Mode on and off on your iPhone or iPad and tell you what happens when you do that.

How to use Low Power Mode on iPhone

Low Power Mode is a built-in battery-boosting feature on your iPhone, iPad, Apple Watch, and Mac. When Low Power Mode is enabled, it can extend your iPhone’s battery life with up to three additional hours of run time before you need to charge your device again.

How Low Power Mode saves battery

Low Power Mode was introduced for iPhone in iOS 9 and for iPad in iPadOS 15. Apple says Low Power Mode “pulls switches you didn’t even know existed.” These switches optimize your iPhone for power efficiency by throttling down its processor and shutting down a few non-essential features like Background App Refresh, mail fetch, automatic downloads, fancy visual effects, etc.

With Low Power Mode enabled, your device temporarily reduces power consumption until you can fully charge it.

What happens during Low Power Mode on iPhone and iPad

During Low Power Mode:

  • Display refresh rate is limited to up to 60Hz on iPhone and iPad models with ProMotion display. iPhone 13 Pro, 13 Pro Max & later and iPad Pro 10.5-inch, iPad Pro 11-inch, iPad Pro 12.9-inch (2nd generation) & later have 120Hz ProMotion display.
  • Low Power Mode disables 5G on the iPhone 12 series (except for video streaming and large downloads).
  • Background App Refresh is turned off.
  • Display brightness is reduced.
  • Auto-Lock defaults to 30 seconds.
  • Some visual effects are affected or reduced.
  • iCloud Photos gets temporarily paused.
  • Automatic downloads are disabled.
  • Email fetch is disabled.
  • CPU may be throttled down by as much as forty percent.

Enable or disable Low Power Mode on iPhone and iPad

When your iPhone battery falls to 20%, it shows a popup asking if you would like to enable Low Power Mode. But you can also enable it manually whenever you want.

  1. Open the Settings app and tap Battery.
  2. You will see a toggle for Low Power Mode. Flip the switch to the on position to enable Low Power Mode or to the off position to disable it.

Note: When Low Power Mode is active, the battery icon in the top status bar turns yellow instead of the standard white, black, or green.

Other ways to turn Low Power Mode on or off

In addition to the Settings app, here are a few other ways to toggle Low Power Mode on iPhone and iPad.

Ask Siri

Invoke Siri and ask it to “enable Low Power Mode” or “disable Low Power Mode.”

To make things super quick, you can even add this shortcut to your iPhone Home Screen and turn on or off Low Power Mode from there.

Use a custom automation

As mentioned earlier, you see a prompt on the screen or the Dynamic Island to enable Low Power Mode when your iPhone reaches 20% battery or your iPad reaches 10% or 5% battery. However, you can use simple automation to automatically enable Low Power Mode when your iPhone reaches a specific battery percentage, such as 35% or 40%. You can even force your iPhone to always stay in Low Power Mode.

Should I use Low Power Mode?

Different people have different needs. Should your iPhone run low on power and there isn’t an outlet nearby, or you don’t have the charger on you, Low Power Mode is a viable option for conserving juice. People who are unhappy with their iPhone’s battery are definitely advised to try out Low Power Mode for a day or two to see if it works for them. But as mentioned above, the extra juice comes at a price.

If you don’t mind manually checking your email and app updates in the App Store, waiting a little longer for your favorite apps to load, and not seeing fancy visual effects, then I’d say these tradeoffs are worth taking Low Power Mode for a spin.

Just don’t use it while playing games, as Low Power Mode was discovered to throttle down the iPhone 6 by as much as forty percent, making the device comparable to the iPhone 5s in terms of sheer CPU performance.

Even if you don’t turn on Low Power Mode manually, your iPhone will still put up a prompt when you’re nearly out of juice, asking if you’d like to turn it on. It’s worth reiterating that Low Power Mode is a completely optional feature, meaning Apple doesn’t force you into using it.

While useful, I do not put my iPhone or iPad in Low Power Mode as it turns off the 120Hz ProMotion display. So, I’ve set up an automation on my iPhone that forces it never to enter Low Power Mode.
