Is there a way to work on a MacBook Pro on >10 hour flights?

The latest version of OS X (Mavericks) is available as a free upgrade, and reports are that it lives up to its promise of conserving battery life. The Mavericks battery monitor also tells you which applications are consuming the most power: you may find find that some seemingly-innocuous background apps are consuming much more power than you expect, and can be safely deactivated.
Other than that, just follow the usual advice. Dim the screen, turn off the wireless, close the laptop when not in use, turn off Flash animations, and so on.
And if you have money to burn, treat yourself tothe latest model Macbook Air. It will easily see you through a 10 hour flight if you’re not maxing out the CPU.
One of the big consumers of electricity is powering the screen. Lower the brightness to the lowest you can possibly tolerate. The other big consumer of the electricity is the CPU. While you can’t avoid using the CPU, you can reduce the strain on it by shutting down any unnecessary programs in the background such as iTunes.
You also need to ask yourself if it’s reasonable to expect 10+ hours of battery power if your laptop is anything less than new. Battery lifetime can be shortened drastically after a couple years of use. From personal experience every laptop I have owned has gone down in battery life by 50% after a year. I’ve improved this number a bit with better battery charging habits, but the decline is inevitable.
But those are more technical tips. As far as travel goes, there are airlines that have outlets at every seat. The only one that I have personally been on to offer outlets and powered USB ports is Air Canada. If writing during a long flight is this important, you should do a little homework to find an airline with power outlets. I know that Virgin Airlines also has outlets and I’m sure with a little searching you will find many many more.
Three approaches:
- choose an airline that has in-seat power.
- get a sheet battery – the one I have for my Windows laptop adds another 7 hours or so – that attaches to the laptop and doesn’t look external, so you can use it in place
- get an external battery and take a break for a little while to let it do its charging under your seat or somewhere the crew can’t see it, then remove it and go back to working
My old laptop used to trip the breakers on planes if I tried to both use it and charge it, so I’d use it a while, close the lid, plug it in and set it aside while I ate or whatever, then pick it up and work again. And yes, I choose my work wisely. If I’m rendering video then my 9 hours of battery life will disappear in an hour or two. Still I occasionally render video on planes anyway.
External battery packs for Macs surely exist. Here’s a review and another review. It says 32 hours for MBA, and 8 for MBP. That should help. And in a pinch, you might even carry two 🙂
Apple claims the 2013 version of MacBook Air has battery that can last up to 12 hours. MacBook Air-Wikipedia
A test performed by The Verge, for example, found Apple’s claim to be accurate, with the laptop running for 13 hours and 29 minutes while “[cycling] through a series of websites and images at 65 percent brightness.” Theverge.com MacBook Air review
Of course, if this guy is coding and testing a CPU-intensive program (such as a 3D game), that will use up the battery faster. But, for “normal” programming, it should be comparable to the test The Verge has performed.
The most obvious solution is to procure an extra, external battery.
