Impact of continuous charging on iPad battery health

Does leaving the charger connected while using my ipad impact battery health and life? Once the level reaches 100% does it stop charging? Thank you.

Per my reply to your post earlier today...


Your iPad will suffer no ill effects through being connected to its Power Adapter for extended periods. Your iPad will automatically regulate and optimise charging - and will not overcharge the battery. 


When used in retail or kiosk applications - where external power is connected for extended periods of time - the iPad may automatically modify its charging strategy and limit battery charge to ~80% of maximum. This modified charging strategy is designed to reduce chemical ageing that might otherwise occur if 100% charge is maintained at all times.


Nominal 100% charging will be restored when a normal charge/discharge routine is restored.
