Summary
While charging the phone overnight with its charger using AC (not USB), in the morning the phone has not reached 100%. This is not occurring all the times but only occasionally. The phone is connected to wifi but no application is actually draining battery.

The phone could take up to 6 hours to charge from 76% to 100% or 4 hours to charge from 85% t0 100% (see screenshots)

Full charge should happen in about 4 hours and take no more than a night in any case
