The solution

Simply turn down the brightness of your screen. Some manufacturers also offer an automatic mode, allowing the screen to adjust to the light that surrounds you. The result is more or less optimal depending on your smartphone, but already saves a few minutes or overtime.

Your battery no longer holds up

Sometimes the problem is not necessarily due to the system: it may be that your battery runs out of steam altogether. If your smartphone a few years, then it is pretty standard. Indeed, a battery is designed for a number of charging cycles. Once exceeded this quota, your battery will gradually falter.
