Bluetooth 6.1 Update Set to Improve Privacy, Battery Life of iPhone Accessories

by

The Bluetooth Special Interest Group (SIG) has released Bluetooth 6.1 as part of its new bi-annual update schedule. The update introduces Randomized Resolvable Private Address (RPA), a feature designed to enhance both privacy and power efficiency.

This new feature makes tracking Bluetooth devices a lot more difficult because it randomizes the timing of device address changes, instead of just using predictable intervals. It also offloads address change operations to the controller device, which should help extend the battery life of the accessory device.

The specification follows Bluetooth 6.0, which arrived in September 2024. That update brought Channel Sounding for centimeter-level location accuracy, lower latency, and faster scanning capabilities, all of which could theoretically enhance the iPhone's Precision Finding feature.

For iPhone users, the upcoming iPhone 17 series expected to be released in September will likely support Bluetooth 6.0 and possibly incorporate the new 6.1 features. All in all, it should bring improved privacy protections and better battery performance when using Bluetooth accessories.

With Bluetooth now on a twice-yearly release schedule, the next update, Bluetooth 6.2, is expected to arrive by the end of 2025 with additional refinements and features.

Glad all of this attention is being paid to Bluetooth. Who knew in 1989 research by Nila Rydbeck of Ericsson would wind up where it is today.

Sounds good. I'll be surprised if it's included with the iPhone 17. Seems like it would most likely be the 18 or later.

I turn Bluetooth off when I'm not using it, which is most of the time, because of the Bluetooth tracking beacons.
While that's generally nice, you do need Bluetooth if you're using wireless headphones or are in a vehicle with wireless Apple CarPlay.

Yeah, I was wondering the same. It would be so much more convenient to be able to update the firmware of BT chips on our devices, instead of having to replace the entire device for a brand new one…
Firmware update is the best way to go. Makes no sense to go buy a new product just to be able to access to newest technology unless your product is really old.

Just a question: Can the Bluetooth be updated via software update or is it some new piece of hardware with the newest Bluetooth technology that have to be installed into the hardware? Just wondering.

Improving accessory battery life is great, but will the device need to conform to the new spec to take advantage of it? Or will devices simply take advantage of teh new addressing scheme?

At any rate, anything that makes tracking more difficult is a win for privacy.
I assume the device needs to have the hardware in place to transmit using the newer standard.
