Low Power Mode is an iOS setting that disables some iPhone features to conserve battery power when it’s low. Your iPhone will ask you if you want to turn on sleep mode when your battery drops to 20% and then back to 10%.

Apple says that the battery saver mode reduces the amount of energy your iPhone uses to extend the life of your battery.
You can tell if you’re in sleep mode because your battery icon is yellow. Your iPhone will turn off sleep mode automatically when the battery charge reaches 80%.
What features does iPhone sleep mode disable?
According to the official Apple support page, Battery Saver makes these changes to conserve charge on your battery:
- Turns off 5G (except for video streaming)
- Sets your iPhone’s screen to turn off after 30 seconds of inactivity
- Reduces the display brightness
- Decreases the display refresh rate for iPhones with ProMotion
- Eliminates some visual effects
- Stops syncing iCloud photos
- Pauses automatic downloads
- Pauses email retrieval
- Prevents background apps from updating
Power saving mode also disables the display of videos in HDR, turns off the Always On display in iPhone 14 Pro and Pro Max, disables automatic video playback, and reduces CPU and GPU performance.
How do I put the iPhone into sleep mode?
The manual way to keep the sleep mode on all the time is to just put your iPhone to sleep every time after charging. You can turn it on manually by going to settings > battery and turn on Low power mode.
You can also turn on Low Power Mode manually through iPhone Control Center or with Siri.
How do I keep iPhone in sleep mode on all the time?
But there is an easy way to “set and forget”. To always keep your iPhone on sleep mode automatically, you need to get a little crafty and create your own Personal automation Use of abbreviations apartment
There are many ways to automatically set the power saving mode abbreviations, but for me the easiest method is to turn on the power saving mode when the battery is less than 100%. This essentially lets your iPhone sleep all the time, but also allows it to back up, complete downloads, and get updates when it’s plugged in and 100% charged.
On your iPhone home screen, scroll all the way to the right to get to yours App Librarythen scroll down and tap abbreviations. Once the app is running, select automation at the bottom of the screen, then tap the blue Create personal automation Button.
Creating a personal automation in Shortcuts takes just a few steps.

On the New animation Scroll down and select battery level. Tap on the bottom option falls underand then move the slider all the way to the right for 100%. Then click Next. You have set your condition for triggering an action.
Now create the action to put your iPhone to sleep. On the Actions screen, click on the blue Add action Button. You can then type “Low” in the search box and type Set energy saving modeor tap scripting and see it below device.
After you add the Sleep Mode action, you can set it to run without prompting.

Once you have chosen Set energy saving modeit will appear on your Actions screen as “Turn on battery saver mode”. click Next. On the following New Automation screen, toggle Ask before you run off so that the energy saving mode is switched on automatically. If you want, you can request a notification for each execution of the automation.
Confirm “Don’t ask,” then tap Finished break up. You are done. Every time your battery drops below 100%, your iPhone will automatically go into sleep mode.
How much battery does the power saving mode save?
You won’t get a definitive answer here. The value of power saving mode has been debated since its release with the iPhone 9. While some estimates say batteries last about one and a half times longer in sleep mode, others show very little difference in battery usage.
If you’re interested in keeping your iPhone battery charged longer, you simply have to try the power saving mode for yourself and see the difference.
My own experience agrees with this early estimate of a battery charge lasting about 50% longer in sleep mode. Anecdotally, I find that power saving mode becomes less important as I use the phone more. The power saving mode benefit seems greater when my phone is idle or being used sparingly for texts and 2FA messaging.
How to get rid of the power saving mode
Disable auto-sleep mode by disabling or deleting automation.
If you find that the low power mode isn’t saving your battery, you can turn off the automation by going in abbreviations and turn off Activate this animation. To delete it completely, on your automation in sleep mode, swipe left on the automation’s main screen, then tap the red icon Extinguish Button.
You can also create your own customized version of Battery Saver by customizing your iPhone settings to take some of the actions that Battery Saver takes. For example, you can significantly save battery by using Stop background apps from updating or Adjust your brightness settings.
