Hello, Most phone use Lipo battery 🔋 if you don’t use phone for long time like 1 week, you have to put battery storage mode You can’t do this from settings etc Storage mode is equal to 3.80v per cell, phones use a single cell, which means 1 s. If you do not have an industrial charger, you have to turn off the phone at 50 - 54 percent charge and put it there, this will reduce the battery life. This method gives the longest usage time, but if you use the phone all the time, you will either buy a really expensive and high-quality charger or use your own charger. Most of it is already charged. The device has a power of 25w, which I think is quite sufficient.
