Bluetooth technology is moving forward again. The Bluetooth Special Interest Group (SIG), the organization that develops the Bluetooth standard, officially unveiled the Bluetooth 6.1 specification today. It's the first update in a new biannual update cycle that aims to drive faster innovation and continuous improvements to wireless communication between devices. And while this may seem like news for geeks, it should also be a wake-up call for most everyday users—especially those who use iPhone.
Privacy protection and longer battery life
The main innovation of Bluetooth 6.1 is a technology called Randomized Resolvable Private Address (RPA). Translated into everyday language: devices will “appear” differently to their surroundings every time and in a completely unpredictable way. This fundamentally complicates any attempt to track Bluetooth devices, for example in shopping malls or airports. While previous systems changed the Bluetooth address at predetermined intervals, the new feature randomly changes the time when this happens. Moreover, the control unit (for example, your iPhone), and not the accessories themselves. The result? Better privacy protection and longer battery life for headphones or trackers like AirTags.
What does it mean for iPhone?
Bluetooth 6.0, released in September 2024, brought features like Channel Sounding – the ability to locate devices with centimeter-level accuracy. In practice, this means an improved Precision Finding feature, which we know from, for example, AirTags. At the same time, latency has been reduced and scanning for nearby devices has been accelerated. Bluetooth 6.1 builds on this and adds an emphasis on security and energy saving – two areas that Apple prefers in the long term. Even though Apple has not officially announced anything yet, it is highly likely that this year's iPhone 17, which traditionally arrives in September, will support miniBluetooth 6.0 at least and very likely 6.1. This, combined with the new chip and improved artificial intelligence, would Appcould bring real changes in the functioning of AirPods, AirTags and smartwatches Apple Watch.
Thanks to the new six-monthly update cycle, we should see Bluetooth 6.2 by the end of this year. It should offer further improvements related to localization, security, and perhaps even connection speed.
Bluetooth is thus confirmed as the cornerstone of the wireless world in 2025, in which Apple plays one of the main roles. And although the changes in version nomenclature may not excite the average user at first glance, the consequences of these changes in your daily use of the device will be more than noticeable.
