Hey guys, I'm on a 2016 15 TB, 16gb/512GB.


Regular surfing, I'm getting about 15W consumption (using coconuts battery tool).

Thiscan suddenly spike to 30-50W depending on the site I'm loading. But otherwise, stabilizes to about 15W.

What are you guys getting?
 
MBP 15", 2.9, 512, 460

Usually around 15W when browsing on Safari.

Can this be lowered with SMC reset? Or is that the baseline?

I've done every possible reset. including a fresh install of Sierra formatting ssd and still have the same value from day 1.

I don't know if its the base consumption or its a bug.

Why would it be a bug? Was it lower in other machines? I doubt it considering SL improved power consumption compared to previous generation processors.

I think it's not a battery problem but the consumption of the components. maybe the real usage of the processor should be of 5-7W and what we see is a bug or an unoptimized firmware

I doubt it, highly doubt it. And wouldn't count on any updates from Apple doing anything more than marginally improving battery life.
 
I get 4-6w on browsing and background productivity apps. 7, maybe 8w on certain video. Flash is the worst, HBOgo uses it. I have a 13" and I know the 15" draw more power, but some of those numbers I'm seeing are crazy. CPU/GPU are doing tasks that are irregular for lack of a better term. Spotlight indexing pops back up once in awhile, ads and trackers, old processes from your old hardware carried over, all will kill battery without doing anything to add to your workflow. I had minor battery issues before like Safari spiking watts between 7 and 12, but that was taken care of with UBlock. There's a lot of little weird things that draw more power than needed. Once these are addressed or worked around, you should be able to get claimed battery. Apple should have optimized software to begin with, but they didn't. I'm sure software will fix these things so that we won't have to tinker.
 
15" 2.7/512/455 @ 90% screen brightness -

5.7w little idle with Safari, Mail and iMessage running.
Between 7-11w while switching pages, opening links, etc., in Safari.
 
15" 2,7/ 1TB / 460 @ 50% brightness

19-23 Watt idle with Safari, Mail and Finder. Horrible 3 hours until empty.
(edit: 6-8 Watt after restart. Seems to be a bit random)

for my 15W surfing average, I'm on Chrome.

Will try later on and do basic word processing with chrome closed and update this thread.
[doublepost=1481177189][/doublepost]one intereting point.

Looking at my top CPU users,
culprits are:
Chrome
Google Drive
Istats menu
Box Driver

And last but not least.
COREAUDIOD --> This eats 4.5% of CPU constantly.

I disabled coreaudio D

http://apple.stackexchange.com/questions/24913/why-is-the-coreaudiod-daemon-using-5-or-more-cpu

And just eyeballing my power consumption, i'm using a ~2-3 watts less.
 
I'm getting between 20-30W with just basic Safari browsing... I don't know how mine is so horrible. 2016 15" 16gb/512/Radeon455
 
I've got a 2016 MBP 13" w/ TB 2.9/16gb/512gb @80% brightness

When idle with finder, calendar, and chrome open I'm getting 3-4W (>10 hrs)
With surfing on chrome (I always have >10 tabs open) I'm averaging 7-9W
With heavier use (multiple videos playing, games) I'm getting ~15W (~6 hrs)
 
Are there different battery manufacturers? Coconut says my battery is made by Simplo, I'm sure my defective TB was a different manufacturer.
 
2016 15" 16gb/512/Radeon460/Simplo battery

Around 20-27 Watt using only Safari browsing (active apps in background Mail, Hipchat, Messages, WhatsApp, Steam, Fantastical2, Steam, Coconut battery (but according to Activity Monitor they almost don't use any energy)
 
Just the fact that 'similar' machines doing similar things vary so wildly in power consumption is weird. I'm still betting on a software issue somehow. In the mean time I stopped worrying. Yes, on battery it will last a few hours, but I have a power outlet nearby most of the time anyhow, so I can live with this. Not prepared to give up on using macOS, and I need a dGPU and refuse to buy a 2nd hand or refurbished 2015.

I get 28W at idle on mine with 70% brightness and the same configuration. That explains my < 3 hr battery life.
 
15/2.7/1TB/460/Simplo using 10.12.1. Have reset NVRAM and SMC.

At about 70% brightness, about 10W surfing Chrome with a couple tabs, Evernote in the background, and one or two message apps. I find 10W and under puts me on pace for about 8 hours of battery.

Power spikes above 20W if I open something like Google Maps (which triggers the GPU). 15W-ish if I'm watching a high-res Youtube clip.
