Reduces automatic shutdown time
When you leave your smartphone after using it, there is a period for the screen to remain completely locked, however this tool can be configured to lock automatically in the seconds that you indicate. The shorter the time it is active, the longer your battery life will be.
Close heavy background-operated apps
Applications tend to send messages or operate in the background, which many times users cannot perceive, however if you are one of those who do not know which apps have these permissions, you can go to the application settings, click on the part where it indicates which ones have permission to use in the background and choose which ones to remove the permission from.
Turn off Bluetooth and GPS if you use it little
If you are at home and you do not use other devices to connect directly with your smartphone, the ideal is to deactivate bluetooth and GPS, as these two services will be constantly updating themselves, which translates into battery use. In some cases you can even define the use of GPS only when certain apps are active.
