Why does battery efficiency decrease a few months after purchase?

Video laden:

Once the charge is completed, the device is directly charged through its cable. However, this means that the battery is kept at its end-of-charge voltage (4.35V), which causes an irreversible deterioration of its lithium during the night.

Video laden:

By using Witty instead, your device is isolated and disconnected from the power grid once the charge has reached 100%. This allows a reduction of the battery voltage to non-harmful values.

Video laden:

Preventing the battery lithium from being exposed to harmful voltage values for a long period of time is crucial to protect your battery health and, consequently, double its lifetime.

The Optimized Battery Charging won’t engage when your usage habits are more variable, such as when you travel. This results in a battery stucked at 80% or mainteined at 100% charge (end-of-charge voltage). Witty A always disconnects the device from the power supply once it has reached 100% charge, avoiding the end-of-charge voltage.
