Battery life may vary based on user and computing conditions.
Mouse battery life isn’t a one-size-fits-all number. It varies more from person to person than just about any other battery-powered device. And there’s no industry standard for calculating it. What is the best battery life, that a typical user can expect to get. But this can vary greatly depending on your situation. A light user might get over three years of battery life with a mouse, while a very heavy user might only get one year with the same mouse.
There are a lot of variables that can affect the battery life of your mouse. While there’s no magic formula to figure out exactly how long your batteries will last, knowing the main factors can help you get a better idea of what to expect—and in some cases help you go longer between battery changes.
- How much you use your mouse: This can vary a lot depending on whether you’re using the mouse all day, every day for work or just a few hours here and there at home.
- How you navigate: The more you move your mouse, the more power it uses. If you use keyboard shortcuts that reduce how much you use your mouse, you’ll get more life out of your mouse batteries.
- The types of tasks you do: Do you spend a lot of time doing mouse-intensive activities, such as browsing the Internet? Or do you spend most of your time typing e-mails or documents that involve very little mouse movement?
- The type of surface you use it on: The tracking sensor uses more power than anything else in the mouse. And the type of surface you use your mouse on affects how much power the sensor uses. While the best surfaces can vary depending on the mouse, in general, it’s best to avoid dark, rough or dull surfaces.
- Unintended motion: On the move with your mouse? Be sure to turn it off with the On/Off switch. While our mice are designed to go to sleep when they’re not being used, they’ll wake up when they move around inside your bag or in your hand—and this movement can use a lot of power.
- The batteries you use: Using old, cheap or rechargeable batteries? All of these could reduce the battery life you get with your mouse. You’ll typically get the most life from high-quality, fresh batteries. And for best results, you should replace both batteries at the same time with batteries from the same package. Mixing brands, types or expiration dates can decrease battery life, too.
