@mrt10001 That's really weird I just popped open the back and checked the model of battery just in case it was replaced but it is the original battery from lenovo model L18D1P32. I will keep investigating...

@mrt10001 I am also experiencing something similar on my X605F (32Gb-3Gb). No data on battery in the stats and shows battery fully charged at all time. Charging is very slow. In android no problem. Did you figure out where this error is coming from? Reported it in the gitlab.
