Hey all, I've started using my Pocket now that the Beta 1.1 has been released, and am encountering some concerning and inconsistent issues with my battery.  I have upgraded my firmware to Beta 1.1.

My battery will sometimes die, showing "Battery Too Low" while displaying 100% battery. When I turn it back on, it shows 0% battery, so I plug it in, and it stops charging at 1% and shows a green light on the bottom. 

I saw one suggestion on Reddit to downgrade the firmware to 1.0b, and then re-upgrade it to 1.1 Beta, which I did. Now, my battery "charges" way too quickly. It goes from 0% to 100% in about 5 minutes, often jumping numbers (ie 42%-47% in 2 seconds). When I start playing it now, the battery drains normally from 100%-91%, and then the battery dies at 91%. 

Last night, I tried charging it overnight to see if it made a difference, and now it's showing the "fully charged" green light at 61%. I have tried using a Pixel3 charger, a Pixel2 charger, and the Nintendo Switch charger, after reading that other users have had success with these, but I cannot fix this.

I have no idea what's going on with this battery, but I'm afraid to play anything on this Pocket now because it dies at random battery levels. I don't trust the display anymore. What are my options here?
