    I charged my Black keyone from 44 to 60 percent then I unplugged it, 10 minutes later (without using it) I put it on charging again and the battery percentage increased quickly from 60 to 68 in less than a minute!

    And no, the battery doesn't drain fast.

    Does anyone have any idea?

    Sounds like it has lost its calibration memory. Try using a lower amp charger and take all the way to full. Like a trickle charge.

    Frankly, I would not worry about it if it only happened that one time and battery life seems normal otherwise.

    Correct me if I'm wrong, but if you were to hold the power for 32+ seconds for the full restart, wouldn't that recalibrate the battery read out?
    Also I have noticed that at work if I were charging my KEYone and then take it off the charge for a short break and put it back on it charges pretty fast.

    Speed of the charge depends on the amperage out put of your charger. More amps, faster charge for any type of battery. Simple as that
