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?

Hey everyone,


Received a new MacBook Pro with Touch Bar 15" as well, and like several of you, was shocked by the short battery life, even with the software updates. After some extensive trial and error, I have remedied my battery woes! Sharing out in case it helps any of you.


The largest change in my case was as some suggested, an SMC reset AND a NVRAM Reset. After doing both, my time remaining shot from 3-4 hours to 9-10 hours and even longer with further tweaks. I was shocked, but was able to verify the change based on using the Battery Guru app. The Milliamp output has been cut nearly in half to ~600 and the machine is significantly cooler during light usage. See below.


A little background:

  • As mentioned, my average was 3-4 hours with light usage. This was playing Spotify, writing emails, and surfing Safari only.
  • I have been using Fruitjuice and Battery Guru to monitor and verify usage time and energy output. Both put the machine at roughly 3-4 hours of battery time and on BG, I had an average ~1100 Milliamp output.
  • Assuming the higher output was the screen, kept brightness to 75% and reduced keyboard lighting to its lowest setting.
  • Confirmed Spotlight, Photos and iCloud had finished indexing before making a judgement.
  • Even after all of the above, still 3-4 hours.


But then: I noticed something was amiss when charging the device. The last time I did so, I found the machine running hot and I noticed the fan was going nuts. That lead to the SMC and NVRam reset. After doing so, voila! 9-10+ hours of battery life!


But not only that, I've been able to extend the battery even more so, doing some additional suggestions that the forums have suggested.:


  • Revisited my startup apps in Login Items and removed things like Skype for Business, Adobe Creative Cloud and several update checkers. Though several of these were negligible, some suggested S4B and Adobe may be eating up more resources and some have reported improvements.
  • Due to the recharge incident, I decided to disable Power Nap while on battery. I'm going to see if I run into the issue again while Power Nap is on charge, will report if it occurs again.
  • Download Turbo Boost Switcher to disable Turbo Boost. I found this adds around an hour of battery life back and the milliamp output can drop around 400 during light usage. Performance doesn't seem to be affected when doing light usage. I turn it back on when I'm working on more intensive applications or plugged in.
  • I keep my keyboard lighting low and brightness around 75%.


Anyway, that's been my experience, and I'm now very happy with the machine and thrilled that I don't feel the battery anxiety I once had. It would seem that there is something glitchy in either the hardware and software still, but hopefully it's just a SMC/NVRAM reset fix for many.


Good luck out there.

So things getting more weird. This timer has really gone wild, but im satisfied about battery life with 100% satisfaction 🙂
Its already the end of the day in my region, i've done all my work today and i've been using it the whole time with medium load (such as Safari 4-5-6-7 tabs (5 mostly), whole time using xCode, a lot of Pages, and i even played a game Human Resource Machine for ~20 minutes and its using dGPU, and just a little bit of Spark, the whole time brightness was set to 75% aka 12 clicks from 0) for about 4-5 hours with 2-3 times of 15 mins sleeping. So look at the screenshot

I dont know why there is 20:31 of use but i do really like that with 56% of charge i have 7 hours estimated time. I think this is really good result

Just relax and use it without any doubt. Just fall in love with it and don't think about your battery time so much, you've got 7 hours of use, for 7 hours i hope you could find a place to charge your laptop. Just wait until the update. I'm sure, Apple does know about this problem, it's 100% software, next update should fix this madness.

JohnZonie: I wanted to mention, in case you are still reading the thread, that I found a setting for Parallels which has substantially reduced its energy use when running my W7 VM when on battery. In the dialog below, the radio button:


(o) Start up and shut down manually


was originally checked. I've since changed it to the second option:


(o) Always ready in background...


The key point, from what I can tell is it also now "pauses when closed or not in use." What appears to be happening is that when I'm busy on the macOS side of the world for 5-10 minutes or more, it is pausing the VM--but in a way where it isn't visually noticeable--and when you cycle back to a window in the VM (I'm using coherence) it picks up without a beat. But the resulting power drain, average, is significantly better.

To JohnZonie - yes it makes a big difference for me. I can essentially leave parallels running when on battery and not really think much about the power draw beyond what I'm actually using. If I'm on the mac side, then parallels is behaving very well power-wise.


For example, I've been preparing a sermon this morning and have been on battery for 2.5 hours with W7 VM "running" the entire time--but really only using a windows-based bible study program periodically during that time. As you can see, energy use is looking pretty good. Most of the time has been spent in two editors (workflowy--a chrome-based outlining app and macvim) and a couple of other macOS-based bible study programs.


You can see that Parallels is pretty far down on the list of energy users for this scenario:

I have display brightness at 50% with keyboard backlight, bluetooth, and time machine backups all turned off.

Seems like there are quite a few anecdotal reports of poor battery prediction and fewer posts with hard data from actual full run-down times. So I thought I'd contribute this snapshot for any who may find it helpful. Have spent the past 8 hours continually using my MBP/15"/16GB/1TB unplugged at 50% display brightness, keyboard backlight, bluetooth, and time machine all disabled. The dgpu was off almost all the time (except occasional websites with a bit of video--and I made sure to close those tabs after accessing the content). Most of the time was spent studying information, both online and locally (digital library) as well as writing. Some of the studying was done using apps within W7 VM running under parallels the entire time. So no video streaming or continuous music--just a fairly representative full non-work day (no SW development, compilation, but ran a few python scripts from time-to-time).


The results: even though I was quite cognizant of energy use, I was unable to get to a full 10 hours. On the other hand, my use involved almost constant typing and user activity (not passive viewing) so the touch bar was lit the vast majority of the time--and as you can see I'm not far off the 10 hour mark (at 8 with a predicted hour left = 9).

Here's what the energy usage looks like after 8 hours in my particular scenario:
