In the moment I am getting 6 hours out of my MacBook Pro 2016 15" high spec doing simple tasks like Safari and Mail. If I edit pictures with Photoshop I am getting around 3 hours. Apple admits that those times are too short but are not capable and willing to improve anything. They say that all the hardware components are working alright so there is nothing they can do. It's frustrating for me as I am a professional photographer and do use the computer often at locations without power supply. I am very frustrated with Apple's arguments and incapabilty to find a solution for that specific problem, especially as I've paid around £3300 for the device.
Got a tip for us?

Battery Life 2017 TB Models

Not solving your MBP battery issue but a couple of power banks will let you charge your Mac on the go.
What kind of research?
Battery has the same capacity. Processor might use the same amount of energy, but because it is faster it might need less energy for the same tasks.
Reason I ask is because I see YouTube videos of people having both who report the 2017 model lasts longer on the battery. Not scientific, but field experience.

Are you saying the 2 ports on the right side of the 13" TB are full speed? How did you know?
It says "upto 40GBPS". So it's not all conclusive to me.
I can't recall what the page said for the 2016 model.
It listed 20 GBPS for the 2016 models also. The 15" models are listed at up to 40, and all they have are 40. Up to 40 means all of the ports are at least capable of 40GBPS, it just depends on the cable you're using. They have to list 20 if some of the ports are only available with 20GBPS.
Doesn't seem quite conclusive to me.

All say “up to 40 Gbps”, even though we know for the sure the 2017 15” and 2016 13” have different capabilities. IIRC, the limitation was due to the number of available PCI-e lanes, which I’m not sure has changed for Kaby Lake.
I'm also a pro shooter with the 15" and I was using the 2015 previously.
I use the 2016 15" tethered (most often to a Nikon D810) and with screen set for 75% I certainly get more than 3 hours while running PS and Lightroom along with a few plug-ins.
Typically I get 5 hours, which is better than last years MBP, though not by a lot. That said, I could certainly get less time depending on what I'm doing, but the Dell units we tried were worse.
What kind of shooting are you doing where you do post on location without power? Most pro's don't do a whole lot of PP without a large calibrated screen, myself included.

Right... Apple used to have a page somewhere advising people to use the left side ports for high performance devices. Can people still find that page and in reference to the 2017 models?
I was investigating the 2017 Macbook Pro 15" model with a Radeon Pro 560. When I looked up the specs, the 560 model was shown to have a 75W TDP.
The 2017 base 15" model has the Radeon Pro 555, which is listed to have a 100W TDP even though the card is less powerful.
It seems to me that the Radeon 560 graphics card in the higher spec 15" Macbook Pro may use slightly less power. Not sure that this will equate to battery life savings but worth considering.
If I've interpreted this info wrong, feel free to correct me.

I believe you've got the numbers for the Radeon RX 500 series desktop cards.

Has anyone seen any tests benchmarking the MB Pro TB 13 2016 vs. 2017 on battery? It would be good to see, especially with both running the latest OSX.
Hi, I'm shooting often environmental portraits for publications, often tethered and somewhere outside, so no power supply. I am not dimming the display down, my clients want to see what the get 
And yes I am doing all my post production whenever I have the time with an external Eizo display at home, but sometimes I have to do it on the spot as it is for edition and needs to be filed over quickly. I am using C1 for tethering though and that seems to use up a lot of battery... well, let's see what the future holds, I was told to wait for High Sierra... best

One of many apps for this. I'm using Battery Health 2, though it will actually shorten battery life! LOL
