Some time after the presentation of the year’s new iPhone model, Apple took the opportunity to surreptitiously upgrade some existing iPhone and iPad models with support for the latest Bluetooth standard version 4.2. The models affected are the iPhone 6, iPhone 6 Plus and iPad Air 2, the remaining mobile products from Apple remains at version 4.0, apart from the latest iPod touch that has version 4.1.
The news in Bluetooth 4.2, released in December 2014 is both less power consumption both during operation and when resting but also faster transfer speeds. Up to 2.5 times higher transmission speeds combined with up to 10 times the capacity (the amount of data that can be shuffled at the same time).
What Apple’s purpose upgrading last year’s models, we know at the moment not, but probably have it with future products to make.
When Apple Watch, BT 4.0 should at least not this first Watch-generation be the reason for this – Perhaps Apple has begun to lay the groundwork for the next generation Watch as reasonably should have BT 4.2.
