Your iPhone will automatically prompt you to Turn On Low Power Mode once the battery is down to 20% level. However, you can also manually Enable Low Power Mode on iPhone at any time and extend its Battery Life by as much as 40%!
Enable Low Power Mode on iPhone
The Low Power Mode feature on iPhone claims to Increase iPhone Battery Life by as much as 3 hours.
This power saving is achieved by reducing brightness, shutting down Email Fetch, Automatic Downloads, Background App refresh, iCloud Photos and other non-essential services.
When iPhone is placed in Low Power, essential services like Calls, Messages will still work as usual and you won’t really notice anything different on your device, other than its screen being less bright and slower.
