The lower processing rate is likely one reason why the battery life when using Bluetooth is 50% longer than when using Hyperspeed. It implements a similar adaptive scheme but depending on implementation at a lower speed than the Hyperspeed technology does. So if there are multiple devices (such as Wi-Fi) using a region of frequency, Hyperspeed technology makes sure that your mouse avoids it and uses a quieter region.īluetooth by comparison hops over a range of frequencies at a rate of 1600 hops per second. It can quickly switch to the fastest and cleanest channel one and prevent lag or stutter.

With this knowledge the internal radio knows which frequencies to avoid and which to use. You can think of this as a tiny spectrum analyzer in every mouse that’s able to perform a Fast Fourier Transform (FFT) quickly analyze the best channel to communicate over. Razer Hyperspeed technology utilizes improved Adaptive Frequency Technology, which scans available and interference free channels every millisecond. Newer wireless devices like Bluetooth and Hyperspeed use techniques to avoid this interference. Unfortunately this causes RF interference and the mouse can experience jitter or lag. This frequency band is shared by other devices such as Wi-Fi, Bluetooth, Microwave ovens and more. A significant difference! RF InterferenceĪll wireless mice operate at 2.4 GHz. Bluetooth on the other hand has a latency in the range of 10 to 20 milliseconds. Hyperspeed boasts a latency of less than 1 millisecond.

The lower the latency the faster and more responsive the peripheral. Latency is a measure of the response time of the mouse or keyboard.

The battery life using hyperspeed is quite a bit shorter than when using Bluetooth.
