Your iPhone will automatically prompt you to Turn On Low Power Mode once the battery is down to 20% level. However, you can also turn on Low Power Mode on iPhone at any time and expect to extend its Battery Life by as much as 40%!
Low Power Mode on iPhone
The Low Power Mode feature on iPhone claims to increase your iPhone’s battery life by as much as 3 hours.
This power saving is achieved by reducing brightness, slowing down CPU/GPU and shutting down Email fetch, “Hey Siri”, Automatic Downloads, Background App refresh, iCloud Photos and certain visual effects like animated wallpapers.
All Essential features like Calls, Messages will work as usual and you won’t really notice anything different than your iPhone being less bright and slower.
In case you can manage to live without the above non-essential services, you can manually enable Low Power Mode at any time on your iPhone and extend its battery life.
Once you plug your iPhone for charging and the charge reaches 80%, Low Power Mode will be automatically disabled on your iPhone and you will have to manually enable it back again.
