Why do our smartphones lose battery power so quickly?

The lithium batteries contained within our devices have a natural life cycle that can be influenced by various factors.

Among these, night-time charging, which lasting on average 8 hours per night, negatively affects the capacity of the lithium-ion cells. In fact, the battery is kept at its end-of-charge voltage of 4.35V even after having reached 100% to ensure that does not discharge during the night.

As a result, the useful life of the battery is halved, forcing us to buy a new battery or change devices .

Here is the solution
