Recently, I feel like I'm getting very good battery life on my MBP 2016 15" - it feels comparable to previous models, certainly. But that's how I 'feel'. Out of curiosity, I wanted to see how long I've been actually using my computer on battery. The only indicator I know of is the one in Activity Monitor - but that just shows how long the computer has been unplugged. During a lot of that time the MBP was sleeping, so I wonder - is there a way to tell how long it has been running with the screen on? A 3rd party app perhaps? (I was a bit disappointed I couldn't find this information in iStat Menus) For example, iOS shows Usage and Standby separately. So, I'm interested in usage time on battery. Thanks!
