But if you’re looking at buying the G903 for a Powerplay mouse, just know it works perfectly. Whether Powerplay is something you need….Well, I’ll let our review address that (expensive) question. When I came back the next morning it had charged up to 95 percent, and from there the mouse continually cycles between 85 and 95 percent to keep the battery healthy. That’s slow, sure, but the mouse is still usable the entire time so it’s not like you’d notice. I received the mouse at 20 percent charge, and it trickle-charged while I used it at a rate of about 1 or 2 percent per hour. Put it on the mouse pad and the mouse charges. The Powercore connects to the mouse magnetically, and this also serves as the charging leads. Non-Powerplay users can stick an optional 10 gram weight in this slot, but Powerplay users will instead insert the “Powercore,” which despite the name is really just another small circle of plastic. Making your G903 a Powerplay mouse is as easy as removing the circular piece of plastic embedded in the bottom.

You can read our lengthier Powerplay review, but I’ll give you a brief rundown.

With Powerplay there’s no need for that cable. At that point, you’ll need to plug in the included Micro USB cable and temporarily turn your G903 into a wired mouse for about two hours as the battery recharges. That’s in line with Logitech’s figures, which tout 24 to 30 hours of battery depending on your lighting setup. I got two to three days of hard use (10-12 hours) out of the G903 while reviewing Divinity: Original Sin II before the battery ran down to zero. Moving from the G502, I entered all my usual dpi settings, and aside from the shape it was like I hadn’t even changed mice.Īs for the battery, even without Powerplay the G903 is respectable. We’ve written at length about the 3366 in the past, but suffice it to say, it’s still one of the most accurate and precise sensors on the market, and the implementation here is spot on. Like the G502 and most other high-end Logitech mice, the G903 uses the PWM3366 sensor. I’ve had zero interference, even in my signal-drenched apartment. That’s the only time I’ve ever noticed that the G903 isn’t wired. There’s about a quarter of a second of dead time when I first move the mouse in the morning, as I go to wake up my computer. The G903 is indistinguishable from any wired mouse I’ve used. Point being, wireless mice used to get a bad rap for being undependable, with interference, low polling rates, bad sensors, and latency among the many trade-offs. When Logitech debuted the G903’s predecessor, the G900, it claimed that its wireless technology (known as Lightspeed) was not just faster than other wireless mice, but also many wired competitors. Logitech has been the market leader lately in wireless technology, and the G903 is another excellent Logitech wireless mouse. That’s the mode I’ve used the majority of my time with the G903, though I haven’t noticed any real difference between the two. If, on the other hand, you’re using the G903 with Powerplay, the mouse pad itself acts as your wireless receiver. If you’re using the G903 as a normal wireless mouse, you’ll use much the same USB dongle as Logitech has used on its other wireless devices for a few years now. Instantaneous, eh? I guess that brings us to our wireless-performance section. There’s no disputing though that the G903 is excellent turning reflexes into registered actions. I get that-the G903 lacks that reassuring “yes, you’ve clicked me” feel that some mice have. Some might dislike how light a touch the G903 demands, preferring a meatier and more solid click. Palm grippers should probably look for something with more support, unless there’s a very good reason to go ambidextrous. I’m a claw gripper myself, and that’s no doubt why I find it easy to go back and forth between scooped and ambidextrous mice. Palm gripping inevitably leads to pinky and maybe even ring fingers dragging along the mouse pad, while a good claw grip gets them up out of the way. That being said, this mouse (as with any ambidextrous mouse) is definitely more suited to claw grippers. You lose the support under the ring and pinky fingers, but the rear is flared a bit outward and nestles right in your palm, giving you the secure grip you need to make precise movements. Using the G903 was surprisingly easy though, and for an ambidextrous mouse I think it’s actually pretty comfortable. I used to use an ambidextrous mouse daily (a Zowie AM) but gave it up for the Logitech G502’s contoured curves-still to this day the most comfortable mouse I’ve used. As I said up top, the G903 is an ambidextrous mouse.
