For me it’s even worse: it will charge to 80% during the times I’m working. So, when I unplug the MacBook to work somewhere off a power source, I’m left with 80%. Then, when I finish my work day, it immediately charges to 100% and stays that way until the next morning. It’s the complete opposite of what makes sense.
