I am having a similar battery issue. It was fluctuating wildly during initial charging. It maxed at 86% after being left plugged in during use first day after update. I unplugged and used battery until completely drained at 0%. I fully recharged it with power off after this and it fully charged at 87% and would not go any higher. Seems like a few batteries are not functioning properly.
