The Rival 3 Wireless has many configuration settings that can improve your battery life. These settings can be accessed in Engine.
These settings can only be changed while the mouse is in 2.4Ghz mode. When the mouse is in Bluetooth mode, it will be automatically set to a polling rate of 125hz and all other settings will be set to their defaults.
If you wish to automatically have the best recommended power saving settings, please turn on "High-efficiency Mode" in Engine.
Even though the Rival 3 Wireless only has a single RGB LED in the scroll wheel, it draws a significant amount of power. Out of the box, the default Orange LED color that we ship the mouse with draws almost 40% of the total power draw from the batteries.
To optimize the battery life, we recommend disabling the LED. (The LED will still blink as needed to indicate the battery level.) If you wish to leave the LED on, we recommend keeping the default LED settings of Illumination Smart Mode and Multi Color Breathe set to "On"
The Polling Rate is the frequency that the mouse sends data to the PC. Out of the box, Rival 3 Wireless' polling rate is set to 1000 Hz. But many folks don't really need their mouse to be set to 1000 Hz for games. Try lowering the polling rate and see how it works for you. Dropping the polling rate to 125 Hz reduces the power usage to almost 20% compared to 1000 Hz.
Sleep timer and Power Switch
The mouse is constantly drawing power from the batteries until the Sleep Timer powers down the mouse. It’s best to keep the Sleep Timer as short as tolerable, and also to use the power switch on the bottom of the mouse to turn the power off right away when the computer is not in use. The default Sleep Timer is set to 5 minutes and it’s adjustable in Engine.
The Rival 3 Wireless was designed to run off 1 or 2 AAA batteries. Running on one battery lowers the weight of the mouse, but it also greatly reduces the time between battery changes.
We also recommend using high quality batteries in your mouse when possible. Rechargeable batteries can be used in the mouse, but please be aware that rechargeable batteries have a lower capacity than their disposable counterparts, so you may have a shorter battery life when using rechargeables.
