I don’t own a chuwi but i do have a bayTrail laptop by i-Life. I bought it for 130$. The way that they implemented the charging is horrible. The charging port is right next to the soc, so, when it charges it heats up the soc as well resulting in heavy throttling up to 0.3 ghz and the right side of the laptop gets so hot to the point where it’s untouchable.
If you’re going to get a laptop, make sure the charging port is on the opposite side of the SoC / CPU.
I personally try my best not to use the laptop while charging since the adapter isn’t strong enough to handle charging and usage at the same time (12V, 2A).
And after exactly owning my laptop for a year, battery has degraded by about 9% (I do charge this everyday) and it’s still enough to last a full day’s work (capacity is around 35 Wh and degraded to 31 Wh)
Good luck on your next purchase
