Putting your phone on maximum brightness can be very energy-consuming. It is therefore better to reduce it if our environment allows it, in other words if there is not too much sun. Auto-brightness is an option that allows the phone to adjust the brightness level on its own depending on the lighting conditions.
It is also possible to switch your phone to “dark mode”, that is to say switch the background color of the system to black. This will allow the device to illuminate fewer pixels and therefore consume less power.
In the same way, replacing your beautiful wallpaper with a black screen or making sure that your screen stays on for as short a time as possible by reducing the time before going to sleep in the settings are other solutions.
