The Viper V4 Pro has been officially revealed.

The Razer Viper V4 Pro has been officially revealed, featuring new sensors and wireless technology, along with an impressive battery life of up to 180 hours.

The Razer Viper V4 Pro has finally launched officially, with Razer announcing an update to its hugely popular gaming mouse line. This new version is lighter, faster, and has longer battery life than before, although the price remains as high as usual.

Competition from more affordable options is increasingly fierce, but with a lighter design and significantly improved battery life, the Viper V4 Pro could once again impress the gaming community.

The most significant change here is battery life. Razer is using the new Focus Pro 50K Gen-3 optical sensor, which only activates when needed, reducing power consumption. As a result, battery life has doubled, from 95 hours on the Viper V3 Pro to 180 hours on the Viper V4 Pro. This is only an improvement of about 30 hours compared to the recently released Deathadder V4 Pro, but it's still an impressive figure. It also maintains that battery life while operating at a fairly fast 1kHz sampling rate, not being limited to the slower 250Hz rate or using Bluetooth (which this mouse doesn't support).

This mouse can, of course, also increase the sampling rate to 2kHz, 4kHz, and even 8kHz, but the result is a gradual decrease in battery life and performance. The new mouse uses the same wireless transceiver introduced on the Deathadder V4 Pro. This rather solid-weight unit, with three green lights to indicate connection status, battery life, and sampling rate, is located at the end of the USB-A to USB-C cable, and you need to remove it to charge the mouse via the front USB-C port.

Another major change in this mouse is the weight reduction, from 54g of the V4 Pro to just 49g. This is still not considered ultralightweight by today's standards, but it's still a fairly light option. For comparison, the ultralightweight Corsair Sabre V2 Pro weighs only 36g, but Logitech's new high-end mouse, the G Pro X2 Superstrike, weighs a hefty 61g.

Another difference compared to Logitech mice is that the Viper V4 Pro has an extra button, in addition to the left, right, middle, and side buttons. On the underside of this button is the DPI toggle button, which can be used to switch between DPI levels with a single press, or if the gamer holds this button while scrolling the wheel, can even fine-tune the settings instantly.

Regarding the switches, Razer has yet to create a replica of Logitech's Superstrike technology; instead, this mouse uses conventional switches. However, these are optical switches, with no latency, no double-click issues, and a lifespan of up to 100 million clicks. Similarly, the scroll wheel uses an optical encoder, which Razer claims is more accurate and durable than conventional mechanical encoders.

Also launching today is Razer Synapse Web, which allows you to configure several aspects of your Razer device via a web interface, instead of having to install Razer Synapse. The Viper V4 Pro is priced at $159.99, making it a typical premium option for a Razer flagship mouse.
