When your iPhone battery falls to 20%, you see a popup asking if you would like to turn on Low Power Mode. But what if you don't want to wait for it to reach that low before being asked to enable the power-saving mode?

Sure, you can manually switch on Low Power Mode anytime you like using one of these three methods. Or, you can automate this task and have your iPhone automatically enter Low Power Mode at the battery percentage of your choosing.

For example, if you want your iPhone to activate Low Power Mode when the battery falls below 40%, 50%, or any other level, you can easily do that.
