I have had my Osmo 2 for around 10 months. I last use it about 3 months ago. Preparing to use it again I got it out to top up the battery. The battery has gone dead flat while stored in the case.
Charging has no effect. One white light flashing with a grenn light flashing while tryin to charge.
I have now been charging for an hour and all that happens is the charge and charge lead get hot and the Osmo gets warm near the USB charge lead intput.
I am happy to replace the battery if that is possible but can find no reference on doing so on the internat.
