Here’s how to have your iPhone or iPad automatically turn on Low Power Mode when the battery charge hits a custom percentage threshold, such as 50% or 40%.

Your iPhone or iPad alerts you when the battery charge falls to 20% and again when it drops to 10%. On older iPhones without Dynamic Island, iOS pops up a message offering to turn on Low Power Mode. On recent iPhones with Dynamic Island, you can touch and hold this alert to activate Low Power Mode manually.
The low-battery notification is handy, but what if you’d like your iPhone to enter the power-saving mode sooner? You can always switch on Low Power Mode manually, but why not automate this task to make your iPhone or iPad activate Low Power Mode when the battery charge hits a custom threshold, like 50% or 40%?
Automatically enable Low Power Mode when your iPhone battery drops to a specific percentage
1) Open the built-in Apple Shortcuts app, select the Automation tab at the bottom, and choose New Automation. If you already have an automation, tap the plus button (+) instead.
2) Scroll down and tap Battery Level from the list of conditions.
3) Drag the When slider to a custom percentage, triggering the automation. For instance, you can set the slider to 50% to have Low Power Mode auto-enable when the battery drops to 50%. After that, select Equals 50% or Falls Below 50% to start the automation when the battery drops to 50% or below 50%.
From the same screen, select Run Immediately so the automation runs without confirmation, and hit Next to continue.
4) Swipe the options under the Get Started section to find and pick the Set Low Power Mode action. If you can’t find it, use the search bar at the top.
5) Make sure the Set Low Power Mode action says Turn Low Power Mode On and hit Done. If it reads Off, tap the word to change the option back to On.
Congratulations, you’ve successfully created custom automation that’ll enable Low Power Mode when the battery charge hits your desired percentage.
Stop iPhone from automatically entering Low Power Mode
If you no longer need this automation, you can deactivate it or delete it.
1) Go to the Automation tab in the Shortcuts app.
2) To deactivate: Tap the automation, and then set Automation to Don’t Run.
3) To delete: Swipe left across the automation and hit Delete.
Your iPhone will no longer automate Low Power Mode
