i have a big problem with my hi13. since two week the battery work only less an hour and the computer stop without warning.

When i used (on battery) my Hi13 and launch big application the computer stop immediatly without warning and i can't restart it if i don't plug in the charger before.
I full charge the tablet for about 8hours on each test.

I check if it is charger problem and change another charger to try. (ali express offical chuwi store send me an additional charger)

Here is the graph i made with the computer data :

When i check the battery is say : ""design capacity 4406 mAh, last full capacity 4406 mAh = 100%" not 10000 mAh

I used the originals chargers .

I try to have answer on aliexpress , mail support chuwi and twitter ... and nothing ... any help ? Please !

What's the voltage for your 4406mAh reading?
10000mAh => 10Ah * 3.7V => 5Ah * 7.4V

Anyway my reading is:
37Wh ~ 7.4V (by HWINFO64)

the voltage depends on the speed of the processor. No matter what type of power management I set up on my PC, the difference in usage time was minimal or the PC stopped suddenly without a warning message.

When I run a game or a heavy application, the battery could be 100% or 80 or 20, some seconds after launch, it was black screen and impossible to restart the PC without replug the alimentation.

Here I indicate that the maximum charge capacity of my battery is ~ 5000 mAh.

The sensors included in the machine only retrieve the max / acutelle capacity + the remaining time calculation.

It is besides with these datasets that I could generate the graph above.

It isn't voltage of the CPU,system,floating in time etc but constant spec. of the battery (combos of the two batteries exactly). Run HWINFO64 and read your stats.

I have contacted Chuwi support and got a definitive answer to this. The battery has a short life cycle. They don't expect it to last much more than a year. 300 to 500 charges.
Nor do they carry many spares, they consider it obsolete and we should buy a new one.
You can obtain a new battery via ebay or such.. based on size and change it. The good news is if plugged in all the time, the device works.
