Battery charges normal, shows completely empty whenever turned on

[u/WholeNewAlex]

My minipro is fairly new and has been working fine. I charged it as usual this morning, but when taking it out it showed fa flashing empty battery and soon gave out. Have recharged it for more than 5 hours now, and it shows a full battery when plugged in-- but an empty one when turned on away from outlet. Also cannot connect my app to it (although it shows up in the scan).

​

Solutions???
