Hey guys. I bought Xioami Notebook AIR 13.3 inch (2018) laptop. Guy that was selling won it as a prize at local contest. Package was sealed, and unopened for a year. So, it's brand new, unused, and he had it for a year stored at his house. When I got it and turned it on, it just said that battery level is low and after few sec it turned off. As expected, because it wasn't charged, but it was stored, so battery drained. I charged it, 100%, used it, and when it comes to 56%, 45%, 40%, depends, it just drops to 0% and says battery low. Here comes the fun part. Yesterday it came to 45% after 2 hours of using (at high perfomance), and after that it just drops to 0%. But, after that, I just kept using it for 2 more hours, until it completely turned off. So, somehow it has false information about battery status. I tried to update windows, and few more tricks but its always the same. It's also fun the fact that I used it today, it came to 40% from 100% normaly, and I restarted it, and it just came with 0% battery left after quick restart. But I just continue to used it normaly, for about 1 hour with 0% battery status. Anyone has some advice? Can it be somehow bios problem? Maybe battery from bios? I just dont know... Tnx!
