Logitech M325 - Battery life, Receiver and Sensor



A simple-to-open panel in the M325’s base gives access to

a single AA battery. This means that once the provided alkaline battery is

drained, it’s easily replaced with an affordable, long-life rechargeable such

as an Eneloop. Either way this rodent won’t have too much of an impact on the

environment, as Logitech claims a single battery will last up to a whopping 18


Obviously we couldn’t test this claim if we wanted to bring you our review

anytime this year, but we have found the company’s battery life claims to hold

up fairly well in the past. There’s a handy little off switch on the M325’s

base too, if you won’t be using it for a while.Logitech M325 2

Also behind the battery panel, you’ll find the slot for

storing the USB Nano receiver, which plugs into your laptop or desktop PC to

allow the mouse to communicate wirelessly.  To be honest we would have preferred an

exposed slot you can just stick the dongle straight into, as found on the Microsoft Wireless Mobile Mouse 6000, but overall it’s a minor quibble. As

seems to be the standard on high-end wireless peripherals these days, the

receiver is tiny, measuring 18mm from tip to tail. When plugged into a USB

port, the protruding bit is a mere 7mm. Logitech M325

As is typical for the majority of Logitech’s wireless

gear, the M325 uses 2.4GHz RF technology rather than the more complex Bluetooth,

so it also offers longer range, and we had no trouble using the mouse from over

10 metres away. Thankfully, and this is a major benefit over rivals, the

receiver is of the ‘unifying’ kind, which means it can be used with all recent

Logitech RF keyboards or mice. Just ‘program’ the device into your single

receiver using the appropriate Logitech software and viola, one-for-all.

Only when we come to the mouse’s sensor do we find our first

disappointment: it uses an 1000dpi optical sensor, rather than the newer and

more accurate laser variety. Let’s put this into perspective for a second

though. On most surfaces and for most tasks, optical is more than adequate.

After all, this isn’t a gaming or performance beast. But with the likes of

Microsoft’s 6000 rival using BlueTrack, which can track across virtually any

surface with better accuracy to boot, it is a limitation worth keeping in mind.

We would love to see a mobile mouse that utilizes Logitech’s Dark Laser tech

for tracking across glass.
