    That’s great that they are willing to fix it, but it is going to be a pain to ship back to china and wait for it.  It also means it is more than just a simple software fix  🙁  Is this affecting all units?  I hope that maybe mine isn’t affected. I’ll find out when it arrives.

    In the mean time, that should also mean they are going to apply this fix to the new tablets that are coming out with Remix OS.  I might upgrade to that just to get the new OS and fixes.  This can be passed to my wife, or sell it.

    do not be so sure that with the upcoming HW release definitely  CHUWI will solve all the problems.
    The first model had the bios chip that melted and was single os
    the second off under the 30% charge
    in Italy it says “there is no two without three”

    the worst thing is that Chuwi doesn’t stop trying to fix their mistakes through SW fixes but continues to produce new versions completely abandoning its customers .
    The only thing They know to say when asked to solve a problem is ” send it to the seller”

    I have the same problem and it shut down at 70% while playing hearthstone. It’s definitely not a gaming tablet

    there are settings in the bios for battery in relation to voltage and resistance. Would tweaking these settings help?

    I know with some older battery technology you need to charge the battery overnight before turning the system on for the first time. Or else it does not calibrate properly and gives a false battery reading for life of product. I don’t know if that might be what is happening. I will charge my tablet overnight before turning it on for the first time. This might not even help if they are testing them in factory, though. I will let you know if this makes a difference. And what do you mean Remix OS? Are they about to change it again? I’m gonna be pissed. (see my earlier post)

    i’m simply pragmatic. just have a look on chuwi chinese and international forum and here on techtablets.

    there are tons of thread all around the world about hi12  issues and chuwi after sale support (may i say customer satisfaction?).

    would underclocking the cpu/igpu help?

    don’t know

    The first batch has got a bad chipset layout.

    Bios chip is too close to cpu and the quality of chip used for bios is one of the worst seen on chinese tablet

    hi all, I tried flashing the bios successfully and I went back into the bios to switch the memory back to 1600mhz.

    But I stopped myself and I gave it a shot at 1067mhz.

    Its currently running at 19% battery and I finished a game of hearthstone. give it a shot and see if ur battery problems go away.

     

    Can anyone explain what vbattery and the ohm settings for batteryID in bios do?

     

    There’s a battery setting under the android sub menu under the advance menu as well. Not sure what that does either.

    Same battery issue for me, my Chuwi Hi12 shutdown itself when is around 27-30% of battery, if I turn it on again it works during 5-10 min and shutdown again, hope Chuwi say something about this cause is a general problem

    Just to update, I ran the battery down to critical 2% and into hibernation.

    the auto shutdown did not happen. Was streaming 1080p YouTube vids with 25% brightness at 70% volume.

    anyway, i can’t feel the difference of the memory at 1067mhz but I’ll try it again another day when I’m feeling more adventurous

    Ben may be on to something. Might be why they sent these out with the memory turned down.  If they used non low voltage memory it might be pulling too much on the system, so they had to underclock it to avoid that.  Can someone else who has this repeated issue also turn their memeory back down and try the same game/setup?

    Ben is, this explains why my Chuwi Hi12 Dual OS was fine when I did the review video. My unit had 1066Mhz RAM and after the reviews I later increased the RAM to 1600Mhz and then is when it crashed! I’m going to move it back to 1066Mhz, you only loose about 10% performance.
