Method 1: Check the Spec Sheet of the Device
The official specification sheet will mention the version of Bluetooth present on your smartphone. The spec sheet will be present on the manufacturer’s website for the device.
Here’s Apple’s iPhone 15’s technical specification sheet, which mentions Bluetooth 5.3. When you open the spec sheet, use Ctrl + F (Windows) or Cmd + F (Mac) to open the search box and search for Bluetooth on the page.
Method 2: Use a Third-Party Website
If you can’t find the Bluetooth version on your smartphones from the official specification sheet—or if the manufacturer’s website hasn’t listed the specifications at all—you can use a third-party website. I’d recommend using GSM Arena. Search for your device and look at the Bluetooth version.
Search for GSMArena, followed by your phone’s name. Find the Bluetooth version under the COMMS section.

Method 3: Download the AIDA64 App (Android)
AIDA64 is a free app available for your Android device. I installed several device info apps, and AIDA64 was the only one that provided information about the Bluetooth version.
Download and install AIDA64 from the Play Store > open the app > go to System > check the Bluetooth info.
Understanding the Latest Version of Bluetooth
Some of the latest smartphones today use Bluetooth 5.3 – this includes the likes of Google Pixel 9, iPhone 15, and Samsung Galaxy S24. Compared with Bluetooth 5.2, the latest version improves latency and efficiency, as Bluetooth 5.3 introduces a new feature called Connection Subrating. Instead of maintaining a constant communication interval, which can consume more power and potentially introduce unnecessary latency, devices can now check-in with each other only when necessary.
You might not notice a tremendous amount of enhancements, but Bluetooth 5.3 offers improved battery/power consumption, performance, and reduced latency.
