Apple boasts of the “battery life varies by use and configuration” and “wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 50%”

On the official website, Apple claims that the battery life was originally tested using a pre-production version of the 2.5GHz Core i5 13-inch Retina Display Pro and then later updated in January 2013 with a pre-production 2.6GHz Core i5 MacBook Pro series. On the other hand, the regular 13-inch Mid-2012 MacBook Pro has an integrated, un-glued, 63.5-watt-hour battery while the 13-inch Mid-2012 MacBook Air has the same integrated, un-glued battery, only with a 50-watt-hour capacity. As for the 15-inch Retina Display MacBook Pro models, they have an integrated and glued lithium-polymer battery but with the 95-watt-hour capacity.

This is largely due to the same integrated and glued 74-watt-hour lithium-polymer battery used in both 13-inch Retina Display MacBook Pro laptops. The same 7 hours of runtime is Apple’s estimate for both the Mid-2012 and Early 2013 15-inch Retina Display MacBook Pro, as well as in the 13-inch regular Mid-2012 MacBook Pro laptops.

Just the same, this is an up-to-date guide which you can find useful if you are interested in getting a new notebook from the used market.Īpple’s official release for both the 13-inch Late 2012 and Early 2013 Retina Display MacBook Pro laptops (A1425), based on the company’s test results, is that these notebooks have “up to 7 hours” runtime in “wireless web” use. In the meantime you already have the tools to start tweaking and optimizing your system.Disclaimer: All models mentioned in this FAQ’s page have been discontinued by Apple.

Note: I acknowledge that setting your system to behave as you expect regarding power consumption isn't as easy as 1,2,3 GO! in Linux and I myself have been researching the subject for quite some time now, I will be updating this answer with a step-by-step guide when the blog post is ready.

Use PowerTop to learn what parts of your HW should be set to stand-by and make the changes permanent by loading them on every boot by using /etc/rc.local and /etc/pm/sleep.dĪs a result of applying these simple steps I could squeeze an extra and half hour when using battery on my crappy laptop (HP Pavilion dv7-4287cl) not to mention it keeps cold almost all the time: it isn't just when using the DIS GPU or 'forcing' the IGD GPU when watching 1080p videos full-screen, running Google Earth and so on.

Use TLP - and ThermalD when your HW allows it.

Switch off your DIS (discrete) GPU if you're not using it.

With that in mind there is a couple of things you can do to achieve a near perfect power consumption performance under Ubuntu - as well under most other distributions:

The biggest problem nowadays regarding laptops becoming hot is the GPU hybrid model as its management still's not fully implemented in all GPUs combinations under GNU+Linux.

It is easy for other platforms to achieve great power consumption performance when manufacturers build their products specifically tailored for those systems following their specs.

GNU+Linux has made a lot of improvements in the lasts years regarding power consumption and most of it thanks not to HW manufacturers but to the amazing hackers that contribute their grey-matter to the kernel and the different open-source related projects as Ubuntu.

But when you install anything else to the same HW - or conversely their SW on another HW - it is logical to expect rough edges and funny behaviour.

Apple manufactures their products in a tightly integrated way to achieve the great performance one often can appreciate on them as such it is absolutely normal that when running their HW with their SW it behave (almost) as an homogenous unit.

There are a few things you can do to get your computer behave as it should when running Ubuntu, I will describe them next but first there is some theory you should know:

No wonder you are having power issues with your computer.
