Depends on battery management system (BMS) built into your device. some Hms is smart. It cuts off charge once battery fully charged. Li ion batteries typicallly have upper voltage limit of 4.1 or 4.2 volts. Once that voltage reached the charge current decreases. Once it goes below certain limit charger should shut off automatically.

Even if it doesn’t the charge current should. Reach very very low values < c/50 where is is capacity.

So I don’t think any damage if u don’t take device off charger. But if manual instructs take it off charger.

Sorry, didn’t get this last statement.

For most rechargeable batteries the best way to use them is to keep charging them up to 100% and then discharging them down as low as possible. If you keep them charged up all the time it would forget what it to have low power. Just like how we fast in Ramadan (phones actually have battery statistics to keep track of this).

In the olden days (3-4 yrs ago ) these power cut-off mechanisms were either not put in place or didn’t always work. To give you an example a friend (Khan) and I bought cordless phones at the same time. I would always take mine off the cradle when it was charged (2-3 hrs per day) where as Khan would always leave the phone on the charge when not in use. The result is that I still have my phone which holds a charge for most of the day and Khan’s phone crapped out last year.

Oh, excellent explanation. I totally get it now.

I’m going to tell my daughter exactly what I tell her about everything she owns: Treat it like a humin. It has feelings too.
