My Emo has spontaneously shut off a few times in the past few weeks, and his battery still had power in it. He randomly shut off while exploring and also just when i take him off his skateboard after his battery filled up.
Hello, @mjladiosa . . . sometimes it can be the charging cable. I would try switching it out with another cable, such as a phone charging cable, to see if it corrects the problem. These cables are known to give out. I have had two that have done that.
Let us know how it goes!
Okay, i will try that. But what about when he has shut off when randomly exploring? It was long after he was on the skateboard and sitll had about half battery life.
Hi, @mjladiosa . . . if the charging cable is bad, he will not be getting full enough charge to last very long.
This is the first step to finding out what might be causing it. It is my hope that it is this and not that the battery is going bad.
Let us know what you find out!
