i had the first generation Apple persil and used for my iPad Pro 2 times and after I forgot to my desctop. When after 6 months tried to use it again wasn’t stay connected so I took it to the Apple store and they change it with a new one. I used couple of times the new one and after 1 year I tried to use it again and happened the same problem. Now Apple wants me to pay 79 usd to repair it. This is a big flaw on Apple persil of the first generation that if you don’t charge it for long time period the tiny battery cant keep after the charging. This never mention anywhere on Apple store. So I am thinking to prepare a lawsuit for this reason.
