When the moment comes to charge your smartphone, it's important to take the right steps to avoid damaging the battery.

The first mistake that many people make is to systematically try to charge it to 100%. It's better to let it charge up to 80% and leave it at that. In the same vein, it's better not to wait until it's nearly completely discharged to get to it. As soon as it reaches a level below 30%, you can set it to charge This simple routine will ensure that in the long run the battery doesn't get overly damaged. In fact, a complete cycle, from 0 to 100%, is only recommended very rarely, just to boost the battery from time to time, without affecting its optimal functioning.
