Edit: 1st Feb 2017. Thanks to Yoni for sending me these photos of the insides of the Hi12 keyboard dock.
Thanks to Matthew from the Forum, we have our first look at the Chuwi Hi12 internals. I haven’t gotten around to opening up mine for a teardown with all the tablets I have stacked up to review. But we can see now and as I thought, Chuwi used a rather large thermal pad to transfer heat away from the Atom X5 Z8300 and RAM and onto the rear metal housing. Cube did a similar thing with the i7 Stylus and it’s rather effective. I would like to see all Chinese tablet manufacturers do this. How much is a thermal pad like this? 10 cents cost to reduce temps and throttling?
Chuwi Hi12 Internals / teardown.
So this was the reason my Hi12 never throttled once or went over 75 degrees during normal use. Even running a ridiculous simultaneous Intel CPU burn and Fur mark test I wasn’t even able to my Hi12 to go over 79 degrees. Most Atom Cherry Trails, at least the first models, always hit 85 degrees and throttle. Hell, even my Microsoft Surface 3 did.
Well done Chuwi, now if you could just fix my Chuwi Hi8 Pro power issues!
Poor Matt’s Hi12 wasn’t so lucky and the display DOA, a suspected display ribbon cable issue for poor assembly line quality control? Remember it’s a bit of a lottery at times. What I call the Chinese Tablet Lottery.

My Hi12 has a problem. The battery has expanded. LCD display has a bulged in the middle.
Any idea how to dismantle this unit and remove the battery. I want to save the main board.

My HI12 had some off brand eMMc and gets 192MBs random reads, everything else seems fine other than the lower spec eMMc than expected.
Can this stuff be replaced?
I am guessing the “e” stands for embedded.

Yes Embedded Multi Media Card, it card be replaced, you must have a BWIN or FORSEE eMMC, they are a bit slower, but it doesn’t really seem to effect performance. It’s down to luck with you get a brand unit. But I didn’t know Chuwi were also using the cheaper ones.

Hey, Chris, can you suggest a good tablet for a kid? Just watching cartoons and playing casual games such as melody puzzles, jewez, etc. At least 5-6hrs runtime.

Hi, something cheap like a Teclast X98 Air III http://techtablets.com/teclast-x98-air-iii/review/ I have a 2 year old daughter and I let her use this with basic learning games and it works fine. Depends on the kids age. But if they are young get one of those super thick cases around it. Battery life depends on the game and screen setting. But it’s better than the cheap 8 imch ones that only last around 3-4 hours and gaming about 2 max. The Air II should be able to do around 4-5 hours. Just remember to power it off to not loose battery in sleep.
