One of the most beneficial features of the 15-inch model has been covertly added to the new 13-inch MacBook Airs.

It appears that Apple has secretly added Bluetooth 5.3 capability to the new 13-inch MacBook Air models, bringing them up to par with the features of the just-released 15-inch MacBook Air.

When the most recent 13-inch MacBook Air model was introduced last year, it enabled Bluetooth 5.0; nevertheless, some keen-eyed web users have noticed that the 13-inch model's specifications page now lists Bluetooth 5.3 (as noted by MacRumors).

Since Bluetooth 5.3 is the most recent version of wireless technology and delivers faster communication and higher energy efficiency, connected Bluetooth devices should operate better and last longer, this is good news for those considering purchasing the smaller MacBook Air have longer battery lives if they can connect to Bluetooth 5.3.

It's encouraging to see the 13-inch MacBook Air join the list of high-end Apple products that support Bluetooth 5.3, which includes the iPad Pro 12.9 (2022) and new Apple Watch models. Although Apple has been hesitant to incorporate Bluetooth Low Energy (also known as BLE) or employ LC3 (Low Complexity Communication Codec) for music, the most recent AirPods Pro headphones do support Bluetooth 5.3. This implies that you won't fully benefit from Bluetooth 5.3 even if you pair the AirPods Pro to the MacBook Air, which is irritating.

Since the Bluetooth 5.3 hardware update is also a compatibility update, it appears that only new MacBook Airs will receive it You won't get this upgrade if you purchased a 13-inch MacBook Air with Bluetooth 5.0 capability last year.

Don't worry if you already own a MacBook Air because Bluetooth 5.0, despite being a few years old, is still suitable for most users. However, for those seeking to purchase a new one, this is a wonderful update that is provided for free to one of the best laptops money can buy.
