    Hey all. I got a macbook pro 13" 2017 without touch bar and I charged it to 100% and rebooted to check how much remaining battery life the activity monitor would show. Could it be true that it shows 15 hours remaining? I uploaded a picture of my programs running and I'm running at full brightness except for the 4 last bars. When I ie. watch twitch.tv streams on 1080p without flash player (with the ht5ml thing) it tend to drop at 5-6 hours, is that normal or?

    It's an estimate based on usage. So with little previous usage it estimates a lot of time. As you use the system more the estimates will grow more accurate.

    How much battery life do you think I'll get if I'm going to study at med school where I would probably be using word and other light stuff? Will it reach the 10 hours as described by Apple?

    From what I have read the 10 hours listed by Apple seems reasonable. But, hopefully people that own the unit will chime in with their experiences.

    If you close Chrome it helps a lot. The battery estimates are estimates, but 10 hours is about right. Some have reported up to 12. Only way to tell is set a stop watch and go use it off power. I watched a film on Netflix last night on battery, and it dropped about 14%. Which I consider pretty good going. Other times I've had Chrome running in the background, AI/PS and stuff, and it's dropped 30% in a couple of hours.

    So depends on your usage, if you're trying to maximise battery life just shut down apps you aren't using.
