Hello, I've recently installed Battery Circle from the F-Droid repos on my SG Wifi 4.2 (UK version).
I don't know how accurate the voltage readings are but I have noticed that when the battery drops to 15% capacity (and you get a warning to plug the charger as soon as possible), the battery is still on 3.55/3.6 Volt, which is way above the safe limit of 3 Volt, as suggested by this article on Battery University:

Over-discharging Lithium-ion
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow.
I've let the battery drop down to 3% and it was still above 3.5V.
I always switch off the device when I charge it, it that makes any difference.
Any clues? Thanks
