Just an update (and a lesson learned), for others that still consider buying gear from Chuwi:
I just received an message through aliexpress from Chuwi:
“We had been trying to solve the issue, and now there is result for the dispute, please do as it shows”.
I’m sorry Chuwi, but I’ve left to open a dispute on the very last couple of hours remaining that were still in my right to return the laptop and get a refund, if I would have waited half day longer, I would have to be stuck with a very expensive paperweight because I really doubt you would do anything to fix a defective battery, as you spend most of the 15 day limit either not answering any communication or trying to blame me for the error (how can it be a customer error to plug the charger and not get a full battery after a day?!?!).
So lesson to others: If your product is faulty, seems Chuwi will do all it can to exceed your limit to return the product and get a refund, so they can offer any crap solution and you will have to stick with it, simply because you have no further options. Also before considering the “cheap prices” and “sales” of Chuwi, take into consideration to look at your local post how much it costs to ship the device back to China with tracking code, because it is not covered.
I work as system administrator and most of my days I need a computer to connect to SSH and Remote desktop to other machines where the work is done, so a cheap laptop with a promised 9h runtime battery with good display and decent keyboard would do the job instead of carrying around 1.5K laptops. If the company didn’t provided me such as awful experience, my colleagues might have bought further devices, as I would have recommended to other light users.
Instead what did I’ve got from trying to give Chuwi products a chance? 20 days of annoying messages exchange with “aftersales”, having to ship back the product to a different place where I’ve bought it from and a 45 euro bill to be paid on my own to send it back with a tracking code otherwise I won’t get my refund.
Honestly, I will have better chances in getting a used thinkpad from ebay than buying a new product from Chuwi.
