G603 Gaming Mouse: More Battery Juice, Minus Flashy Lights

Having a wireless gaming mouse is all about accepting compromises: along with superior mobility, freedom, and performance, you also have to deal with frequent battery recharges. As one of the Titans in the world of gaming peripherals, Logitech has several solutions to this problem. A charging mousepad is a pricey option. But if you want something else on a budget, the G603 might be just what your pocket can handle. Read on to find why.

Main Features

The G603 is a wireless gaming mouse from Logitech, with a focus on battery life. Instead of inbuilt rechargeable batteries, the G603 uses AA batteries to power its internals wirelessly. It promises 500 hours of gaming and 1400 hours of regular use on a pair of these batteries. Other than that, the features are pretty basic for a gaming mouse. You get the Logitech Software Suite and a new High-Efficiency Rated Optical (HERO) sensor with max 12000 DPI.

Design & Ergonomics

This is a mouse designed for right-handers, so it does not have any ambidextrous features. The extra thumb buttons are on the left, and the ergonomic slope is towards the right.


Logitech G603 LIGHTSPEED Wireless Gaming Mouse

If you are familiar with another premium Logitech wireless gaming mice series like the G703, this mouse should look pretty familiar. In fact, it is almost indistinguishable from the G703 on a cursory look. It has a generic mid profile curve, which works well for gamers who prefer a palm grip or a claw grip. On the whole, the mouse is comfortable to grip, nothing special.


The main buttons have a smooth and firm feel and click. The scroll wheel is plenty wide, with a textured rubber grip. The side buttons are also quite firm and easy to reach. The clicking action is not the softest though, and this might hamper you in RTS games where you need rapid clicking.

One thing that sets apart the G603 from other gaming mice is the total absence of any lighting. And this makes perfect sense if battery life is your primary focus. But if you love programmable RGB lights on all your gaming gear, the G603 is not the mouse for you.

Software & Customization

With such bare-bones button setup and no lights, the software for the G603 only needs to be functional. This mouse uses the same Logitech Gaming Suite used by other peripherals from the brand. The software shows battery info, DPI settings, and button customization options. There are lots of commands to choose from, even though the number of buttons is limited.

Gaming Experience

The sensor onboard the G603 is almost flawless, which something you would expect from a brand like Logitech. It has some really impressive numbers. With low latency, and 200-12000 DPI tracking at 400 inches/second, this is a very smooth and responsive mouse indeed. There is never an instance when you feel like you are not in control. But one thing you will have to get used to is the weight of the mouse in your hand. Those two AA batteries inside push the weight of this device north of 130g. If you want a lighter feel, this mouse will work with a single battery as well.

The battery performance also seems to live up to its promise. We are not yet sure if this will last for the promised 500 hours of gaming, but the early signs are very promising indeed. You can definitely expect at least four months of gaming from this mouse on a pair of AA batteries at the very least.

Final Thoughts

If you want a simple, straightforward wireless mouse that doesn’t clamor for a recharge every few days, the G603 is a fantastic choice. It is based on a very reliable sensor and mouse design and has enough features to keep the average gamer happy. The lack of lighting effects is entirely justifiable and not a significant con at all. Serious pros might need something more premium, but for everyone else, the performance on offer here should be good enough.
