So.. I managed to get 10 hours on my 13 inch MacBook Pro. I've already decided I'm not keeping this thing, but before I sent it back, I've been running countless ways to achieve 10 hours of battery, and I think I've finally figured it out. It is obtainable... turn your screen brightness to about 70%, then, find a video that's local to the hard drive. Make sure auto brightness is off, then make sure you close all programs ( no mail fellas ). Once you do that, go ahead and make sure -everything- is closed. No battery management software ( I couldn't do this even with battery health 1, or 2 running ), anyhoo, close it all. go ahead and start the video, If you have anything other than half volume up, you won't get 10 hours, so set your volume to about 50%.. once you do that, start the video, and start a stop watch. Make sure you're at 100% battery, don't unplug once you hit 100%, use a battery monitor to ensure you're at the max capacity. Once you do that, play your video in full screen, and set it to the side. With what I listed above, I got 10 hours, and 5 minutes of battery usage. I did the same thing, and had slack / mail open, and got 9 hours and 15 minutes ,I did the SAMe thing, and had safari, mail, slack open, and got 8 hours and 45 minutes. I did the same thing and had mail, slack, safari, and I also had photo's syncing with my phone, I was gone much of that day, and my photos were obviously syncing, I got 7 hours, and 10 minutes. There you go, you now all know the super secret to getting 10 hours of battery life. Apple didn't lie to anyone, they just didn't do any real world expectations. I did manage to squeeze 9 hours and 25 minutes on my very first try, I noticed when you watched a popular youtube video in a loop, the touch bar would light back up during a commercial, not sure why, but this drove usage time down to about 45 minutes less than the it remains off, and it will remain off if you watch a video on the hard drive. I'm assuming you can probably get the same battery life if you did it streaming, but I did not try, doing 10 hour tests all day every day unfortunately becomes time consuming lol. Note : this is a touch bar model, has the I7 3.3, 256GB disk, and 16GB ram.
