While the sixth-generation iPod touch shipped with Bluetooth 4.1, the original iPad Air, iPad mini 2, and iPhone 5s all remain on Bluetooth 4.0.īluetooth 4.2 notably promises up to 2.5x faster speeds and up to 10x greater data capacity over its predecessor, as well as improving privacy, security, and power efficiency. At some point following the September 9th announcement of the 2015 iPhone 6s, iPhone 6s Plus, iPad Pro and iPad mini 4, Apple quietly modified the tech specs and comparison pages for 2014’s iPhone 6, iPhone 6 Plus, and iPad Air 2 to bump them all from Bluetooth 4.0 to Bluetooth 4.2, the latest version of the increasingly popular wireless standard. Changes to Apple’s published tech specs for various products are rare, but when they happen, they’re typically interesting - and under-the-radar.
