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.

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?

Plug-and-forget nano-receiver

You can forget about it

Here’s one less thing to worry about when you’re on the go - your wireless receiver. That’s because our plug-and-forget nano-receiver isn’t just small - it’s tiny. You can literally plug it in once and forget about it.

See all mice with a plug-and-forget nano-receiver

Leave it and love it

With most wireless receivers, you need to plug and unplug them every time you pack up your notebook. The plug-and-forget nano-receiver is different. It’s so small it stays nearly flush with your notebook - so it’s always ready. You just turn off your mouse and go.

It’s a stowaway

If you ever want to store the receiver, you can do that, too. Plus, because you’re not using it, storing your receiver will help conserve battery life.

Depending on the mouse you’re using, you can put the nano-receiver in the storage slot (inside the mouse) or slide it into a port (on the back of the mouse) and - presto! - your mouse turns off.

When you’re ready to get back to business, you simply press the eject button to release the receiver, plug it into your notebook, and start working. (Did we mention the nano-receiver is plug and play?)

Pint-sized power

Sure this little guy is about the size of a small coin, but it packs plenty of power. Nearly all mice that come with the nano-receiver offer Logitech Advanced 2.4 GHz wireless connectivity.* That means you’ll experience virtually no delays or dropouts, even in the busiest high-tech environments, such as an airport, a coffee shop, or your neighborhood coffee shop.

If it weren’t so easy to forget about, you might just find this receiver unforgettable.

* The Logitech® VX Nano Cordless Laser Mouse for Notebooks was introduced before we offered Logitech® Advanced 2.4 GHz wireless.

Mice you can get comfortable with

It all adds up

Do you spend a lot of time with your mouse? Repeating the same hand and arm movements over and over again hundreds, if not thousands, of times a day? Even the littlest difference in design can make a big difference in your comfort.

Logitech mice have all sorts of features that help increase your comfort and help reduce the amount of movement, effort, and strain needed to get around your computer.

A natural fit

If your hand had a choice in the matter, it would naturally take the angle of a handshake when your arm is bent.

We figured nature might be on to something and created mice that are sculpted and sloped to let your hand take a more comfortable, handshake-like position. And that means your hand can relax.

See all sculpted mice.

A better grip

You lift and move your mouse again and again, all day long. If it’s hard to hold, it’s going to put a little extra strain on your hand. But don’t worry—we added non-slip rubber grips to many of our mice to increase friction and make it easier for you to hold and grab your mouse without squeezing.

Pick out an easy-to-pickup mouse with rubber grips.

All about angles

Extending your wrists and flexing your fingers for hours may not feel so good. That’s why we make low-profile mice that reduce the angle you need to extend your wrist. And we carefully place controls so that most hands can use them without flexing fingers more than 45 degrees.

Navigating to comfort

Comfort features aren’t the only ones that help your hand out. If you can get where you want to go faster, your hand does less work. Less work equals more comfort.

Hyper-fast scrolling lets you fly through 10,000 lines of a spreadsheet with a single spin of the nearly frictionless wheel—something that would take 1,000 spins and seven minutes to do with a traditional scroll wheel. In the long run, that’s a whole lot less work that your finger has to do.

Check out all mice with hyper-fast scrolling.

Want more time-saving controls that can save your hand, too? Side-to-side scrolling plus zoom, application switching, and Forward and Backward buttons all help you do more things with less effort.

See all mice with advanced navigation controls.

Smooth moves

Is your mouse fighting your moves? We’ve got mice with slick, low-resistance feet that allow them to glide more smoothly than your average mouse. When your mouse resists less, you don’t need to work as hard.

Find a mouse with low-resistance feet.

The easy track

You can even choose a mouse that doesn’t make you move very much at all. A trackball mouse stays in one place—you just move the ball with your finger or thumb. Plus, customizable buttons help you do more, more easily.

Logitech® Advanced Optical Tracking: More Mousing on More Surfaces

From Amazon® to Netflix® to Facebook® , the computer has become the hub of entertainment and information. But in order to enjoy all computers and the Internet have to offer, you need something to help you navigate through this vast digital world. That’s where the trusty computer mouse comes in.

While more and more people are using laptops and netbooks, many prefer the ease of a mouse to the tricky finger maneuvers needed to navigate with a built-in touchpad. However, thanks to the portability of these computers, mice are now being used in more places and on more surfaces—from the local café’s metal tables to your tile kitchen countertop to the polished wood desk in your home office. Glossy surfaces such as these can be a challenge for standard optical mice without a mouse pad. But who wants to carry around one more thing?

Logitech Advanced Optical Tracking can track on most of these challenging surfaces and improve battery life—making it an ideal choice wherever you use your mouse.

Tracking innovation: It’s all about the angles

When Logitech engineers sought to improve the performance of optical technology on these glossy surfaces, they took inspiration from laser mice—which offer more precision on more surfaces than their optical counterparts.

Standard optical and laser mice have the same basic components—a light source that illuminates the surface beneath the mouse, a lens that captures the scattered light and a sensor that processes the image captured by the lens. The more surface detail the light can illuminate, the easier it is for the sensor to identify reference points that it can use to accurately measure motion.

The main differences between optical and laser mice have been the light source used and the angle of the sensor. Standard optical mice use an LED light and look for scattered (or diffused) light from a sensor directly above the surface. Laser mice use laser light, which illuminates surfaces in far greater detail than LED light, and typically look for scattered light from the specular (or reflective) direction, which also helps illuminate greater surface contrasts. Because of the stronger light source and more efficient placement of the sensor, traditional laser mice are superior to standard optical mice at tracking on smooth, glossy surfaces with little contrast such as ceramic tile, metal and polished wood.
(Some Logitech laser mice can even track on glass thanks to their use of darkfield microscopy.)

Tracking innovation: It’s all about the angles

Building a better (optical) mouse

While Logitech Advanced Optical Tracking uses LED light, we’ve moved the sensor from a position perpendicular to the surface to an angle similar to that of a laser mouse. Logitech mice with Advanced Optical Tracking look for scattered light from the specular (or reflective) direction—like a laser mouse—instead of capturing light from above—like standard optical mice.

By changing the angle, the sensor can collect more light and get a clearer snapshot of the surface. And as a result, the sensor registers surface contrast better. Because Logitech mice with Advanced Optical Tracking can process more surface contrast, tracking is more precise over a greater variety of surfaces, including many of the smooth, glossy surfaces that are problematic for standard optical mice. And—as an added bonus—because the sensor collects more light than a traditional optical mouse’s sensor, less light is needed to illuminate the surface. So mice with Logitech Advanced Optical Tracking can conserve power and you’ll enjoy the convenience of a longer battery life.

Get into your digital world

If you think about it for a moment, when you have a mouse that tracks on more surfaces and gets a better battery life, then you can forget about the tools (i.e., the mouse) that help you get into your what you love more, and focus more on what you love. While that might not be sexy, we think it’s pretty important.
