Until a few weeks ago, the MB Pro was almost always on a desk with an external monitor and power cord attached. More recently, I have used it on battery power. I'm surprised at how quickly the battery charge seems to get low when I'm usually just checking email and on the internet (very little video playing). Battery System Preference shows condition as Normal.
Somewhere I read to check the Energy tab in Activity Monitor. Currently it reads as follows:
Remaining charge: 38%
Time remaining: 2:03
Time on battery: 9:07
What is the meaning of the last item, Time on battery? I think somewhere I read that it's the time since the laptop was last on external power. I assume, given the 9 hour number, that includes time the laptop isn't even being used.
Edited: One more observation. A couple of times recently when I did a video conference (Zoom meeting which I do in browser) if I start out with a well-charged battery, say 85% or higher, it usually goes down to about 5% at the end of an hour. Is that to be expected?
