 * Background app refresh is disabled.

Low Power Mode is automatically turned off when a charging an iPhone or iPad reaches 80% battery life, though it can be manually enabled again. A user is normally prompted to turn on this feature when the battery level of their iOS device has been drained down to 20%, and once again at 10%. iPadOS users only receive a single warning at 10%.
