At ZDNET, we follow a comprehensive testing method to evaluate Bluetooth trackers and provide insights into their performance and reliability to help buyers choose the best one for their circumstances.

We test Bluetooth trackers by noting the entire experience, from unboxing and setup to features and performance. This involves evaluating whether the location tracking for a Bluetooth tracker is accurate when compared to its actual location, monitoring signal strength when trying to find a tracker, and assessing how reliably it connects and reconnects to your main device, which is commonly a smartphone.

During testing, we also evaluate the maximum signal range, the app experience, and the effectiveness of proximity alerts, measure the battery life, perform drop tests, and test how each Bluetooth tracker performs in areas with a lot of Bluetooth interference.
