Hi again. Today I have charged it and it has a 14.4%. What can i do?

Hello, i have same problem of you.

By anywy tablet come discharged when you first got it and can’t power on before charge? If yes lithium bateries get damaged when they are very time discharged, discharge bellow 3V (each cell), full charged for a lot of time. Wear can’t be fixed. I will build a pack myself to solve the problem

+1 cycle, drop to 35W total with 17.9% wear 🙁

Also i have buy two new dedicated 12V chargers stabilized (power brick 3A/5A), both do the same issue of ghost touch. It seen only to like my universal charger…

Also i have made a driver set for who want to update drivers to the most recent versions and safe, will upload latter

Yes its horrible, here in Portugal it took almost 2 month to get the goods if they stop at custom check… Sometime they forget packages and return them without refund

Dam thats a way to high! Gov is terrible, sucking all our money and doing bad stuff with it

I’m from Brazil, the tax hungry Country. I’m glad you are managing to solve your issues.

That explains the high tax… I’m from Portugal, tax here is high too 23% + 10 €, but using priority line we can avoid it (Gearbest and banggood. Not Ali…)

New update: Tried a good stabilized 12V transformer and works without touch issue!

Now i have plugged a usb c hub to test it (HDMI/USB3.0/USB-C/RJ45) and it works. After disconenct i see sparks from tablet USB-C connector and screen do some horizontal blank lines and disconnect the keyboard xD This tablets have a very high quality 😀

What is your country?

I only buy from gearbest and Banggood because no EU Tax, otherwise aliexpress all the way too.

And i can say Banggood have the best service for return, because they instant refund postage fee and send replacement before recieve the faulty unit, after i have sent the photos of package and receipt they sent another replacement. Gearbest is trying to scam me, 1 month after they recieve my tablet and still they say not recieved, full tracking and they still saying not recieve and have to wait…

Also i will not send this back, if battery goes worse i will build a pack my self and replace it using the pcb and wire from the original.

I already have done the heatshink mod, getting 20-28ºC idle and max 70ºc burn test

Chuwi from Gearbest with same touch problems, returned and get a worse unit with serious problems

Cube i7 book from Banggood, touch problems, and now they sent me a unit discharged over a month or more

Battery report says 11% wear, 2 cycles with me

And the fun fact was in both times a fear that could happen (get a even worst replacement

Note: First Chuwi i get from gearbest havent touch issues when charging, but scren cracked, my luck i guess

It’s the secound time in row i send a china table to warranty for a replacement and i get a worse unit 🙁

[Tiago Conceição]

Now i got other problem (i think and i still testing) when i get this tablet it have 0% charge, it took a while before i can turn it on. As i know lithium can’t be discharged to low levels or damage may occur. And i think is the case… I charge to full 100% then i disconnect and windows report 50% battery only, automaticly drop 50% after remove the jack, and windows battery report show same result from 40.000mW to 20.000mW. I fear i get even a worst tablet because this one may have a battery that is already damaged. At least other table come with more than 50% charge at first use 🙁

I will try another cycle to test

[Tiago Conceição]

I doubt about that but i will try on other houses too. If is a housing AC problem should type c have same problem? both chargers are not grounded.

But yes they should drop that DC jack and provice already a good type charger

Hello again

I have recieved today the replacement, i test it again and still same problem… Touch issues when charging.

This time i have buy a good USB-C Charger and use it directly on tablet and problems gone, no more touch issues. From now i will use alywas the USB-C Charger. They should build cube i7 and future tablets with usb-c charger in box instead of crappy power supply
