Notification on charge complete

[SubhadeepJasu]

Battery health is very important for laptops, and the easiest way to kill batteries (for some devices) is to leave them plugged in after they have charged fully. An user aware of this may still be late in reviewing the charging status.

This can be fixed by having a notification (high priority) that says "Charging complete. Please unplug you device", something along those lines.

We can also have a notification (low priority) when the battery reaches the 80% mark ("Your device is sufficiently charged"), because technically charging the battery above 80% usually puts additional strain on it. Its like trying to fit more passengers in a bus. Even though the bus isn't filled yet, the filling process is significantly slower. In case of battery, the resistance increases which causes more heating which causes more damage. (Optimal range of operation that ensures maximum number of cycles is 60% to 80%).
