    Using Chrome and Safari.


    Apple completely replaced my 1 month old 15" MBP with touch bar at the Apple store in Boston.

    One of the managers said that he has seen bad battery life on a small handful of new MBP's and that Apple was starting to hear about this issue.

    You seriously get 12 hours of battery life with Safari while at 80% brightness, and this is with timed real-world results, not just estimates? And this is a MacBook Pro 2016 15"?

    Out of curiosity, what is it that you like about Chrome that would make you sacrifice battery life over using Safari?

    Day 1: I am seeing slightly better battery performance but not a huge difference from my previous machine. This confirms (for me) that this is most likely a Software/Firmware issue that Apple should address in *.2, or *.3.

    Yup, but I can also seriously get 4-5 hours when I'm using a heavy workflow of Xcode, Postman, Slack, Photoshop etc. Also, I noticed Dropbox using a lot of cpu when nothing major seems to be happening.

    Chrome has a much better plug-in library, and I personally like the interface better. Once they adopt touch bar, I will switch from Safari

    Been having a close eye on this thread. I had the same problem as many of you have described and I tried the following:

    1. Reset SMC
    2. Reinstall Sierra from boot with Option + R (I restored at first from Time Machine backup)
    3. Run diagnostics with Option + D
    4. Install Sierra 10.2.2 Beta (16C63A)

    I have used the MBP on a regular basis, browsing, watching movie with VLC, typing in Word, etc. Before I could get 3.5 hours but now it shows me about 7.5 hours, which is better than before. If in fact it's 10.2.2 that have contributed to the increase in battery, I look forward to get the final release and hopefully it will give us some peace of mind.

    This isn't the first time I have experienced myself battery issues with a new MBP but I was patient last time and Apple came through. I hope they will this time as well.

    Current statistics are:

    - Remaining charge: 87%
    - Time remaining: 6:18
    - Time on battery: 1:08

    Forgot to mention that I also disabled Siri and Spotlight indexing. Will wait for a while before turning them back on just to see what happens.

    I have noticed that Microsoft Outlook for Mac is TOTALLY draining my battery life way more than any other program. Has anyone else noticed this? Using 15 inch W/ Touch Bar.

    Apple really should just make at least one of their laptops a bit thicker like they used to. To give it amazing battery life, power, graphics etc... without it costing 5K of course.

    Spoke with Apple Care support today and told him two things:

    1) I am not happy with the battery time of 7 hours since it has been marketed as to 10 hours.
    2) I have tried everything to fix the issue (NVRAM, SMC, update to latest beta, clean install of Sierra, etc)

    He acknowledged that Apple know this issue and (surprisingly) told me that the laptop needs to go into repair. When I asked how come, his reply was that the battery is faulty and needs to be replaced.

    He could not give me any further details whether this issue was limited to the initial batch but that replacing the battery has fixed the issue for previous customers. Finally, since I got the laptop a couple of days ago the customer agent told me that if I would still not be happy after the repair I would be able to get a refund. Obviously, he was confident about the solution.

    Since I really like the 2016 version, I am going to give Apple a chance to fix it. But I have to admit, in line with many of you, that this is quite an embarrassment on behalf of Apple.

    Now, I am on my way to hand in the laptop to get the battery replaced. I will report back with the results once I get the laptop back.

    10.12.2 was just released, not seeing any release notes related to battery improvement unfortunately. Maybe 10.12.3?

    Monty, very interested with what Apple replies with. Please update when you can, thanks!

    In my case (no battery issues to begin with) it was more like a 10-20% improvement. Still significant though.

    Lot of users reporting 8-9-10h of battery life after updating Sierra

    Seriously, about 25% of the web pages I try to access with Safari go into this endless loop, "Error on page, reloading". Safari has some serious problems, none of which are being solved by Apple. Its been this way through several releases.

    After the dramatic improvement I had with 10.12.2 (16C67), I updated again to 10.12.3 Beta (16D12b), sad to report that battery is back to old 4-5 hours, I have coconut battery installed so I can see consumption all the time, with 10.12.2 (16C67) consumption is around 5-7 W most of the time, but with 10.12.3 Beta (16D12b) its around 9-11 most of the time, so its not an estimation or a a shot in the dark, these are actual numbers for consumption

    I had Outlook 2016 running all day yesterday with no significant effect on battery drain.

    Just wanted to add 10.12.2 has fixed my battery issues completely. Not at first, I was getting 4hrs surfing in safari and watching movies in iTunes. Battery Health 2 said I was discharging at 20w.

    I booted into recovery mode and reinstalled Sierra having read this would replace all the system files, leaving my apps and data intact. It did exactly that and now with the same usage I discharge at 5.5w and get 11-12 hours real world usage.

    How long did it take you to complete this process?

    from hitting reinstall to being back on the desktop around 30-40 minutes which included downloading a fresh copy of Sierra I guess.
