Here is the thing...
Yes the phone has a voltage shut off when it reached 100%.
However, it will start to drain battery immediately once it cuts off charging. Even when idle with teh screen off it uses some power. And once it drops to 99% it will start charging again until it reached 100%.
Depending on your set up and how much the phone runs when idle it would keep 'topping off' the battery several times overnight. This is harsh on the battery.
So it's not like once it cuts off charging it stays off until it's unplugged and replugged in. It'll keep charging everytime it drops to 99%
Never have I felt so close to another soul and yet so helplessly alone
As when I Google an error and there's one result
