iFixIt tears down the Apple Smart Battery Case

Yesterday Apple surprisingly — well, to me anyway — released the $99 iPhone 6s Smart Battery Case. Now iFixIt has torn it apart to look at its innards. You should read the complete teardown, but here are some of the highlights:

  • Apple uses a soft, reinforced elastomer hinge design to accommodate all that bump in the trunk and to allow your phone to slide easily in and out of the case. 
  • With 7.13 Whr (1877 mAh at 3.8 V) capacity, this battery more than doubles your iPhone 6s (6.55 Whr) capacity.
  • For such a smart battery, it looks like most of the brains probably live in software on your iPhone.  iFixIt only found some rudimentary ICs inside: NXP NX20P3 load switch, also found in Lightning to USB cables; and NXP 1608A1 charging IC, also found in all of the new Magic accessories
