Place the second battery in a USB-powered docking station, where it can be charged while you use the first. When the battery starts to run low, the mouse alerts you with a flashing LED, allowing you to quickly swap it out for a fully charged one. This means you can basically enjoy infinite battery life with the mouse, minus the half a minute it might take to change the battery. The process is very easy and very fast.
Is it more convenient than having a built-in battery and plugging in a USB-C cable from time to time to charge while in use? Maybe. Maybe not. But you don’t have to worry about the mouse having a tail that restricts your freedom of movement and affects accuracy.

SteelSeries Sensei Pro: a new approach to wireless connectivity
A single charge is said to last 16 hours in performance mode, which means a high polling rate of 8 kHz (the mouse can handle up to 9 kHz with so-called overpolling). That seems correct. Perhaps best suited for esports players who need extreme precision or professional graphic designers who want a level of precision beyond the ordinary. If I switch to a more modest 1kHz polling rate, the battery life increases to about 60 hours, depending on the specs.
The other new feature is that it doesn’t communicate via a 2.4GHz RF signal or 2.4GHz Bluetooth, like almost all other wireless mice. Instead, it uses new Ultra Wideband (UWB) technology and the charging station also acts as a receiver. Plug it into a computer to power the charger and the mouse will connect automatically.
UWB is a wireless standard designed primarily for short-range positioning and is also used in some other devices, such as electronic car keys. Here it uses a high frequency of around 6 GHz and, as the name suggests, greater bandwidth per channel to transmit data more quickly.
This gives you the benefit of a very high polling rate and even shorter response times than possible at 2.4 GHz. It is also much less susceptible to interference. At 2.4 GHz, you have to compete with other Bluetooth devices and even Wi-Fi for the same radio spectrum. Here you largely save that. Not that I’ve ever found this to be a problem, but who knows, there may be situations where it makes a noticeable difference.
