2016 macbook pro 15" with touch bar poor battery life

Pselok, I have no idea what might be causing this. Maybe a software bug or the iGPU needs optimisation, not sure. One thing's for sure though, the draining to 0% method worked for me. Look at these results, after a day's work! (About 2 hours of sleep in the "Time on Battery", so this adds up to a solid 10 hours)

Yeah, i saw it, thats nice, im happy you're good with this thing. Just a few hours ago i've been able to see 8:30 estimated on 80% and after an xCode update and Spotlight i can only see 4 hours 🙂

You're right. Wished they had listened to me the first time. Have to think about asking for a replacement or a refund. Not very happy with it right now, and seeing all these posts not really confident another one will behave as promised. First generation Apple product. Allways something not right.

Well, its not hard to discharge it 🙂

Give it a couple of days / at least a week.

I had problems with only getting 4 hours..

I get at least 9 every charge now.. Thats on safari, watching activity monitor, iMessage, coconut battery open and Spotify at times.

I am currently on 30 hours of my battery with still 19% (obviously a solid 15 to 20 hours of it was asleep) but that still is around 10 hours while I'm on it along with losing a couple % here and there while asleep.

I have also had Lightroom opened for about 30 minutes during this period too which takes up A LOT of energy.

I am currently on cycle 13 of my battery charge and I am getting the correct reads.

Never had problems like this with Apple. Untill this year. The MBA for my girlfriend came out of the box with a hinge that wasn't attached correctly, so the screen lost its connection ever more often. Had a lot of discussion in the Apple Store before they were willing to repair it for free. The TimeCapsule I bought came out of the box with a faulty harddrive that stopped backing up everytime after a few runs. It took Apple three months to acknowledge the problem and replace it. An iPhone 6s came in january out of the box with the battery issue Apple only recently acknowledged, mine first came back repaired but had still the same problem, only then I got another one (a refurbished one, that is). So maybe you understand that I am not so confident that everything will be fine in time, or otherwise Apple will help me. Besides that: I need the machine, and I need to get to work again. Don't have time for this. It should come out of the box perfectly. It's expensive enough.

I think I'm on to something. I think is the WindowServer. Its CPU usage is almost constantly 130%, so that's way to much by any measure. Found an article on this: https://www.macissues.com/2014/10/20/prevent-the-windowserver-process-from-dragg ing-yosemite-down/ and a guide to solve it on this forum (although related to an external monitor, which I haven't): Guide: How to solve Yosemite memory leaks and CPU usage. Reduced the tranparancy, changed the systemfont back to San Francisco (hate it), quit Dorpbox and Sync, and did everything the guide said, but it hasn't helped. Anyone has some suggestions?

[I was unable to start up in Safe Mode, don't know why, so just Onyx instead to fix permissions. I did the SMC-reset as I did before, but wonder how one knows if it's succesful, since these machines don't have an orange/green light anymore on the charging cable.]

It's a normal things? I cant fully charge it, Sierra shows 100%, but CoconutBattery shows 95%. And since December 05 i've lost 100 mAh of battery? what?

Same thing here. Mentioned it before. Discrepancy between what the MBP says en Coconut Battery says. With me also a difference of 5 percent.

The app which i use "Battery Health" says i have more W or V cant remember what it is than my capacity , lol.

Update. Did a clean install, nothing further. Again I get a enormous battery estimate of more then 17 hrs with the battery charged 87%. CPU-usage of WindowServer is down to 2 percent. So what can cause is to run on 130 percent? Anyone an idea? Besides that: what is this WindowServer anyway? Don't have it on my MBA. Something to do with the Retina screen or what?

Once you understand that estimates are what they are it's not so difficult to understand why it changes, if the power consumption is high the estimate will be short, if low then it will be long. Windowserver is part of OS X that draws Windows on your screen, it is supposed to be there otherwise you would not see anything. In general it is best not to guess what is happening.

In other words: I should stop thinking about it and be happy with an expensive computer that has a battery time of less then 2 hrs and gets so heated up and can't barely touch it? Well that's helpfull. And I couldn't have guessed it has something to do with displaying windows on my screen. Therefor the name! Wow. What would be more helpful is some suggestions as to what gets this part of the OS to draw a crazy 130% of my CPU.

I don't think I said that, perhaps you can quote it as I believe that you just made that up.

Mate why are you still fighting this through. You and we know there's something wrong with your machine. If you're not happy get it replaced.
