If your phone is constantly going flat then here are three simple ways to save your phone battery.
Turn off your data
For Apple, go to “settings”, “mobile data” and turn off your data so that the icon is no longer green.
For Android phones or tablets swipe down from the top of the screen, go to settings, click “data usage” and then flick the “mobile data” icon to off.
Disable Location Services
For Apple, this is found under “settings”, “privacy” and then select “off” for “location services”.
For Android, again go to “settings”, “location”, “Google location settings” under “location reporting” and “location history” switch the slider bar off for each option.
Dim your phone brightness
For Apple, this is found under “settings”, then “display & brightness”, then slide the brightness bar down as low as it can go. Additionally you should turn off “auto-brightness”.
For Android, go to “settings”, “display” in the “device” section, “brightness” and adjust the brightness to the lowest level.
Please note that Samsung phones are are very similar to Android devices but sometimes have small differences.
