2016 macbook pro 15" with touch bar poor battery life

I just received my new 15" MacBook Pro with touch bar. The battery life is horrible!!! I have Safari open with 6 tabs and with 95% battery, I am told that I have under 3 hours of battery life left! I thought these things were supposed to get 10 hours? I ran the battery down in 3 hours last night only browsing the web. I wasn't watching videos, just browsing. Is there something wrong with my laptop?

Can anyone say what is yours Full Charge Capacity of the 15" with touch bar? Having the same battery troubles but after reducing brightness from 100% to 75% i have a 2 hours advantage. I jumped from 4-6 hrs to 7-8 with 75% brightness and light use such as safari with 2-3 tabs. Still far away from 10 hours of "heavy" apple using.

My Full Charge Capacity jumps from 6830 to 6880 is this normal? What is yours?

No, I am a macOS developer so I have access to beta software. I was having issues with 10.12.1 so I figured I didn't have much to lose and low and behold it seems they may have found a fix. My best guess is something to do with the Photos app trying to parse facial recognition data in the background and hanging for some reason. I noticed after the upgrade that Photos dumped its derived data cache and re-created it. My laptop ran with high CPU for about 40 minutes then everything spun down as normal and I am on track to get about 8-9 hours of battery life using 10-15 apps regularly at 75% brightness.

I have the problem of poor battery life. I do not run Photos at all. I don't do anything more graphics-intensive than occasionally playing YouTube videos. Yet in a session where all I have done is email and web browsing my computer still thinks it has a battery life of about 3.5 hours. So the problem is not related just to graphics-intensive programs like Photos.

I am also victim of the dreaded battery drain on the new MBP with touch bar. I'm lucky if I get 4 hours on my 13" fully specced machine. I have ordered a replacement from apple which arrives next week.



Whilst waiting for the new one to arrive I have also been experiencing problems with my Time Machine backups failing. Whilst troubleshooting this with Apple over the phone, we discovered that my HDD is showing it's SMART Status as "Not Supported". This is obviously a fault. The support engineer susects that this is very likely the cause of the battery problems I'm experiecning as well. Might be worth checking if you are seeing a similar problem with your HDD (can be viewed in Disk Utility when focussing on the physical drive). I hope my replacement does not have this same issue!

LidoShuffling: Hope you are correct. Mine says S.M.A.R.T. not supported as well (2 TB SSD). Seems logical that this would not be supported on SSD although I suppose there could be bad memory slots even on an SSD that need to be skipped. Never checked on previous MacBook Pro (early 2012 with 750 MB SSD). My battery life on new 15" with TouchBar has slowly grown from less than 3 hours on a full charge to more than 8.5 hours just by using it for a couple of weeks. I'm hopeful this is fixing itself.
