iFixIt Tears Down New Unibody MacBooks, Discovers 10-Hour Battery Is Backwards Compatible
With their usual alacrity, the dissection fiends over at iFixIt have again donned their Kruger-like gloves tipped with T6 Torx screwdrivers and gutted a freshly speed bumped plastic unibody MacBook.
Not surprisingly, there’s not a lot of new information: since only the CPU, GPU and battery have changed since the last MacBook refresh, there’s not much new going on in the innards.
However, there was, at least, one pleasant surprise: the new plastic MacBook’s 10 hour battery is an easy swap into older unibody plastic MacBooks. While dropping a new MacBook battery into an old machine isn’t likely to get you the full 10 hours of battery life you’d expect from the newer models, it should still get you some extra oomph…. a nice bonus if you happen to get your existing MacBook’s battery replaced under warranty, and Apple efficiently drops one of the higher-capacity batteries instead.
