Powering your mouse

The power of convenience

For you, having a wireless mouse is all about convenience. Any time you need new batteries it’s a hassle.

That’s why we’re hard at work figuring out ways to extend the battery life of every mouse we sell. And it’s why we make some mice that let you go more than a year without changing the batteries. Because we happen to think that fewer batteries are better for you. (And better for the planet, too.)

On and on and on

The longer your battery life, the less hassle you face. No lugging around batteries when you’re on the go. No wasting time and money on frequent changes.

Pick a mouse with batteries that last a year, 15 months, 18 months—or even three years—and you might just forget it runs on batteries at all.

Charge, not change

Don’t want to deal with changing batteries at all? We’ve got rechargeable mice, too. You just place your mouse in its recharging stand or plug in the USB cord when you’re done using it, and you’ll always be ready to go.

Check out all of our rechargeable mice.

Bells and whistles

Mice that turn off automatically. Buttons that help you conserve battery life. Battery indicator-lights.

Many Logitech wireless mice are designed to help your batteries last longer. By automatically putting your mouse to sleep when you aren’t using it. By offering On/Off buttons that let you manually turn off your mouse. With battery indicator-lights that help prevent surprises—so you know you can count on your mouse when you need it most.

Some mice combine auto off, On/Off buttons, and battery indicator-lights.

If you love the convenience of long battery life, Logitech mice will make you happy. In fact, the Logitech® Marathon Mouse M705 will last you up to three years without a trip to the store for two AAs.

But do you ever wonder how we determine battery life? And what about the disclaimer that’s on every box? “Battery life may vary based on user and computing conditions.”

In this article, we’ll power you through all the details and go behind the battery-life scene.

Behind the numbers

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. We do our best to come up with a 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.

So how do we calculate our battery life? We studied a variety of real mouse users and created a profile of a typical user. We then used that to create a simulation that we run on actual mice.

During the simulation, we measure how much power the mice use and come up with a battery life estimate—taking into account factors such as how battery voltage changes over time, which impacts how much power the mouse uses.

Behind numbers
The big factors  

The big factors

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.

Looking for a mouse with a battery life so long you won’t remember the last time you changed batteries?
