Hello,

XPS 15 9570 user here. My laptop was about half charged, when I put it to sleep and tried to open it again after about an hour. I immediately got a message that the battery is critically low and I had to plug it in, and it went into hybernation. I plugged it in, and the battery went up to 43% almost instantly. 

It seems like a bug, given that the battery was actually not drained. Anyone else had the same?

Here is the battery report:

Thanks for the help.
