Use Low Power Mode to reduce power usage on iPhone
Low Power Mode reduces the amount of power that your iPhone uses when the battery gets low. It optimizes performance for essential tasks like making and receiving calls, sending and receiving email and messages, accessing the internet, and more. On an iPhone model with ProMotion display technology, Low Power Mode limits the display refresh rate to 60 frames per second.
Note: Your iPhone might perform some tasks more slowly when in Low Power Mode.
If iPhone switches to Low Power Mode automatically, it turns off Low Power Mode after charging to 80%.
