Tried your charger trick but no effect. Still waiting for full discharge. Poly was fully charged when this happened. Just disconnected MojoPoly from the charger a few minutes earlier after a whole night charging session, went to the bus stop, turned on the device, started Gofigure, turned on Hotspot mode, and that was it. The same thing happened several times before with earlier firmwares. Discharging takes around 20 hours as I bought it in January so the battery is still in good condition. (When I'm clever enough I switch on Hotspot mode before connecting it to the charger so I don't have to wait that long for the full discharge. I forgot to do it last night. I prefer Hotspot mode on the go because it reduces the wifi noise on my sensitive IEMs and because it's simpler to connect the phone. Maybe I will have to reconsider it because of this recurring annoyance.) Looking forward to charging it and using it tomorrow. Today I had to use Mojo via cables which was very inconvenient. I am pretty happy with Poly when it works.
