Stay clear of the Hi8 Pro for now, many users including myself have powering on issues and battery calibration problems. And even some owners have reported the units dying completely in the forum.
It was all smooth sailing for my Hi8 Pro, until it suddenly died on me with around 36% battery when running 3DMark. It powered on 3 times and off, finally reporting I had 2% battery. So I suddenly lost 34% battery? Or it was almost dead to begin with it seems and the battery levels are not being reported correctly. It would not power on, but holding the power button for 12 seconds and then letting it charge overnight it’s alive again. But others haven’t been so lucky.
So for now, I recommend the Chuwi Vi8 Plus which is working perfectly, with good thermals and free of this issue.
Chuwi Hi8 owners. Do you have issues with your Hi8 Pro? Please post in this thread.
Update:
Well as soon as I posted this I got a message from my Aliexpress seller, Chuwi is aware of the issue and working on a software fix. A bios update I guess?
