The only chance for a fix is to replace the battery with one that isn’t trash. I will return mine, it’s not worth the money if the tablet can’t be relied on.

And I have no idea why it can’t play 4K, I suspect some corners were cut and there is a bottleneck somewhere, not good.

The battery  gets better and better for each charge. I am on my 5th charge and this time it give me 7 hours and 16 minutes with screen on all the time and brightness set to 25% I did normal websurfing an around 2 hours youtube. But its very strange it cant play 4k videoes.

define “4k videos”.

z8300 have hw decoder for both h264 and h265 up to 4k so it should play smoothly, when the software is properly using acceleration.

if you’re using a software that does not, and/or view a file that is compressed with another codec (say, vp9 for example) then no acceleration for you.

Try using Furmark. I’m on battery at 75% atm and the moment I start the stress test at any resolution it triggers the shutdown.

This entire tablet model has defective internal power regulators by design.

Edit: When connected to a power supply, Furmark draws 7-8.5 Watts, something that’s clearly beyond this battery. Maybe all Chuwi is guilty of is not installing proper buffers to simply ensure so much power is never requested on battery.

Try to go into intel graphic panel, and choose power. Then turn of power saving for games.

Now I got something new.

After the screen was turned off and I turned it back on, every few seconds there would be a massive artifact on the screen until eventually the whole thing powered down. Power consumption was a mere 2.5W at the time.

This tablet is trash, not going to waste any more time on it.
