I'm happy to take it apart and put a new battery in, though it would be nice try a non-destructive way first - is there a recommended way to drain the battery? Wait ages? Short pins on the USB? No power lights, so no way of knowing if it's even on.
Thank you so much for the suggestions
EDIT: Got the back off, battery (fully charged?) voltage is 2.92V, whereas it should be 3.7V
