Apple's refreshed 12-inch Retina MacBook has been carefully torn apart, revealing the upgraded internals that makes everything work like magic.
Here's some of the take away from iFixit:
The battery's form factor seems 100% identical to the multi-lobed cell we found in the 2015 Macbook.And yet somehow, Apple managed to squeeze in a 4% capacity increase from the 7.55 V, 39.71 Wh battery in last year's model. Apple claims this new 7.56 V, 41.41 Wh Li-ion power source should provide up to 11 hours of iTunes movie playback.We're guessing this capacity increase is owed to improved battery chemistry (though it's also possible that Apple's engineers have shaved away just enough material from the lower case to allow for a thicker battery).
Bottom line, this year's MacBook is exactly like last year's MacBook — except in the ways Apple's made it better.
