TL;DR in bold.
Whenever I boot my 2015 13" MacBook Pro from sleep (I leave it for 10-16 hours in sleep), it boots up and often times the battery % shown is stuck at 100%. I have to reboot the system to get a proper reading on the battery %. The same goes for storage when this happens... storage remaining reading is constantly "updating" until I restart.
I was using my MacBook Pro for about 15 minutes, and noticed it was stuck at 100%. So I restarted. When I restarted, it showed 100% battery life still, and then went from there. So obviously the system recalibrated, but incorrectly. After those 15 minutes, I should've been down to 97% at least, given I was running videos.
An additional 30 minutes later and I'm at 95% battery life, but the system keeps reading in the range of 4-6 hours of battery life left. It never reads 9+. I am running nothing in the background, brightness is at one notch above 50%, Wi-Fi is on, and I'm on a fresh reboot. I'm only running Safari and Spark. Nothing is out of the ordinary in terms of the battery usage information (no apps are hogging anything at all).
I seem to get proper battery life out of the machine, but it's always estimating much less battery life than I am getting. And, given the battery life remaining shot back up to 100% after a reboot, I wonder how accurate that is?
When I operate at about 55% battery, if I'm web browsing only with no videos, I usually get 5% battery life to 30 minutes, which is the correct 10 hours. I just don't understand why the battery life estimate never ever reads 10 hours remaining. I've only seen "7 hours remaining" maybe once or twice over a few days of usage, nothing ever over that.
