I have experienced it on multiple mobile phones and my laptop. If i charge the battery to 100% the discharge to 99% is way slower than if i charge the battery to 90% and discharge to 89%. And this makes me charge the battery to 100% even when I know that it is bad for the battery just because the charge lasts much longer than charging to 90 or 80%. Is it related to some kind of chemistry?
I am ok with eli 20 also. Thanks.

My understanding is that when you charge to 100%, it is really ~90% (for example), which is the “safe spot” you are thinking of. Thus if you charge up to 100% for a little longer, you really get closer to “100”. And then as you use battery life and it starts to drain, it isn’t really registered as falling until you get down to the point where the software was telling that you were at 100. So effectively, it is not a linear sliding scale yet. By contrast, if you stopped charging at 80 or 90%, say, then you are already in the linear sliding scale, and you see the delta in % immediately.
Similar to how old cars’ gas tank gauges behave. You fill the car up beyond the 100% point, and fuel starts to fill the path to where the cap is screwed on, then as that gas is consumed, the car still sits at 100% Full. The gauge starts to move after you settle into consuming what’s in the actual tank.
I think.
