How's the battery life on 2018?

[Pangalactic]

Since Apple has upped the batteries a little bit and the new MBPs run on new hardware, has anyone had a chance to test the battery life on the new machines?

This is something I also would like to know. Especially how the battery lasts in normal non-demanding web usage. Not that interested in battery life when crunching numbers with 4 cores. Then I'd anyway plug it in.

... the first reviews seem to indicate that the battery life of the MB Pro 13 (2018) is not very well ...

Can you post links?

Damn, looks like 15% less Battery life than on the previous model (yes, depending on configuration).

This is the only one I was able to find. Its hard to measure realistic battery life when the thing is still so new. Takes a about 8-10 full charge cycles for the battery to really calibrate itself so I wouldn't take too much stock in these super early reviews. If other reviewers and publications echo these battery claims, I'll be pretty disappointed. With my current Pro, I can only get 6 hours with the least intensive workload I can do (few Safari tabs, Pages, Evernote & iTunes open with 60% brightness). I was hoping it would be closer to 9 hours but we'll see.

Way to early to judge this. Ask again in a month when all these machines are broken in

I'd guess they are as much "broken in" as when the earlier models were reviewed: immediately after the release. So there should be no difference there whatsoever.

Waiting on 15" battery life performance w.r.t. last year's also. I'm expecting decreased performance due to ddr4 and hexa core CPUs. I would be very surprised if anyone reports increased battery performance compared to last year especially considering how apple is touting such performance leaps from last year. Usually if there is such a big performance leap, then the battery department takes a hit. After all this is a laptop. It has to give in somewhere in exchange for better speeds. I don't think 10% increase in battery size is enough to offset the increased power consumption, but we will see what the media say.

So the hex core chips are 45Watt chips. Last years quad core chips were also 45Watt chips. 45Watt = the power consumption. Why do people keep thinking they consume more power when they are rated with same power consumption ?? The RAM might use more all right

Id love a comparison between the 13 inch touch bar 2018 and the 2017 macbook pro(Without touch bar which is the one that I have now) as far as as the battery life..since I want to upgrade

TDP doesn't mean much in the sight of real life applications. I've seen reports that the hexa cores pull in as much as 90w. It is not as simple as believing what the paper says. I wish I could just believe I could get 10 hours of battery life as apple claims and believe it because it was 45w from last year and it hasn't changed this year hence it will be the same. No, it doesn't work like that. Anyone would be foolish to take their claims for granted without proper testing.

That’s the thermal design envelope for a family of processors. Real power consumption is entirely different. Unless you believe 4 core and 6 core Coffee Lake both magically consume 45W.

I believe thru improvements in the silicon they engineered them to have the same TDP on average - even if individual processors might vary from that depending on flaws and usage patterns etc

Actual TDP varies even for processors within a power family.

TDP is for thermal engineers so they don’t have to design several dozen cooling solutions for different processor bins.

For example, 65W for Intel simply means the processor won’t likely dissipate much more than 65W under normal circumstances.

Generally speaking, the 13” touch bar from 2016 wasn’t exactly great for battery life (Apple went from ~76w to ~49w if I recall off the top of my head) - I’m sure the latest revision will be around the same or a bit longer, but the 10 hour mark was hard to reach for most users and reviewers - 5-6 hours of general use is what I understood from what I’ve read, with a few who managed to get 7-9..
