I have the same problem. The battery life was great for the first couple of months, then it suddenly got much worse (that was about 6 months ago). It will go quite slowly (approx. 2hrs) from 100% to about 65%, then drop very quickly to about 15%, and take a couple more hours of use to deplete to zero. I’ve tried recalibrating a couple of times but didn’t make any noticeable difference.
The attached screengrab from HW Monitor is confusing – designed capacity is less than half the full charge capacity. Has anyone else seen that? Could it be because there are 2 batteries and the software can’t handle it?
