Logitech G915, G915 TKL and G613 Wireless Gaming Keyboards Compared

The Logitech G915 and G915 TKL suit players who want a slim low-profile wireless mechanical keyboard with Lightspeed and Bluetooth, while the G613 suits buyers who prefer a full-height tactile keyboard with six macro keys and an AA battery that lasts for many months. The G915 X is the newer generation of the low-profile line, so anyone buying new in 2026 should look at it before the original G915 unless stock or pricing favours the older model.

The G915 and G915 TKL

The G915 line is Logitech’s low-profile wireless mechanical keyboard, first released around 2019. It uses low-profile GL switches in three types: tactile, clicky and linear. For the GL Tactile, a listing gives 2.7 mm total travel and a 1.5 mm actuation point at 50 g. The brushed aluminium faceplate is praised by Tech Report for resisting fingerprints and grease, and for very little flex.

Connection options are Lightspeed wireless with a 1 ms report rate, Bluetooth, and wired USB. Digital Trends says Logitech rates the TKL at about 40 hours at full brightness and the full-size model at about 30 hours, and a Logitech representative reply on a retailer Q&A page backed the TKL figure. The TKL measures 368 x 150 x 22 mm and weighs about 810 g, while the full-size weighs about 1,025 g.

Charging is by micro-USB, with Logitech claiming a 0 to 100 percent charge in under four hours. Digital Trends says you can keep using the keyboard while it charges. TechSpot and other reviewers note the micro-USB port as a disappointment for a premium board, and a 2026 review calls it outdated.

Strengths and Limits of the G915 Line

• Strengths: thin body that suits a low wrist angle, strong build, reliable wireless link, quick actuation from low-profile switches, three switch types, per-key RGB, wired and Bluetooth fallbacks.
• Limits: price tier, micro-USB on the original, limited keycap options (Digital Trends notes it is incompatible with most mechanical keyboard accessories), switches that some find less clicky than expected, and no wrist rest or USB passthrough in the box according to Tom’s Hardware.

The G915 X Generation

The G915 X launched in September 2024 as the follow-up to the G915 released about four years earlier. Gaming Nexus reviewed the G915 X TKL, and Versus lists the TKL at about 860 g and the full-size at about 1,080 g, both 22.6 mm thick. The new GL switches use a cross-style stem instead of the earlier hook system. Switch options are clicky (48 g), linear (43 g) and tactile (45 g), with the tactile having a 1.3 mm actuation point and 3.2 mm total travel.

Battery figures differ by source. Gaming Nexus cites 46 hours for the TKL and found it roughly accurate, GamerGear lists up to 42 hours at 100 percent brightness and about 100 hours at 50 percent, and Versus lists 40 hours. There is also a wired-only G915 X at about 1,040 g without a cable. In short, the X generation changes the switch stem and refreshes the build, and the base idea of a slim Lightspeed board stays the same.

The G613

The G613 is a full-height wireless mechanical keyboard from around 2018 that uses Logitech’s Romer-G switches. Listings give a 1.5 mm actuation point, 45 g actuation force, 3.2 mm total travel and a rated life of up to 70 million keypresses. Jabba Reviews calls the switch Logitech’s answer to Cherry MX Brown, so expect a tactile feel.

It supports Lightspeed 2.4GHz (1 ms report rate) and Bluetooth, with multi-host use over Bluetooth. It has six macro G-keys and multimedia hotkeys. Size is 478 x 216 x 33 mm, and weight is 1,410 g without batteries and 1,460 g with two AA batteries. Logitech rates two AAs at up to 18 months, with a low-battery warning at 15 percent shown by the keyboard LED and in Logitech Gaming Software. PCWorld said the 18-month figure appears to apply to Bluetooth, and Lightspeed will cut life a bit, while Techaeris said Logitech claims the figure over Lightspeed. Reviewers could not test the full 18 months.

None of the sources consulted addressed whether the G613 is discontinued. Windows Central calls it a few years old but still a good option, and Logitech’s current store pages should be checked for availability. The G613 suits users who want a tactile board with long battery life and macro keys more than slim looks.

Low-Profile vs Full-Height Switches

Low-profile switches have shorter travel and actuate sooner, which Tom’s Hardware credits for the G915’s responsiveness in games. The trade-off is feel: Tom’s Guide says they take a little getting used to, and others find them less clicky than expected. Full-height Romer-G switches in the G613 have a longer 3.2 mm travel and a conventional keycap shape, so they feel familiar to anyone used to standard mechanical boards. If you rely on aftermarket keycaps, the G613 and most full-height boards offer more choice than the G915 line.

Size and Desk Fit

• G915 TKL: compact, about 368 mm wide, leaves room for mouse movement.
• G915 full size: adds a number pad and is heavier at about 1,025 g.
• G613: 478 mm wide and 33 mm tall, so it needs a deeper desk and a bit of space for the macro column.

Compatibility and Software

The G915 line works with Logitech G HUB for lighting, macros and profiles. The G613 is listed with Logitech Gaming Software, and reviewers note its low-battery warning in that software. Bluetooth lets either keyboard connect to a laptop or tablet, and Lightspeed uses a USB receiver for the PC. Console use depends on the console accepting USB keyboards for the games you play.

Frequently Asked Questions

How long does the G915 battery last?

Digital Trends reports Logitech rates the G915 TKL at about 40 hours and the full-size G915 at about 30 hours with lighting at full brightness. Dimming or turning off the lights extends it. The G915 X TKL is quoted from about 40 to 46 hours depending on the source.

Does the G915 charge with USB-C?

Reviews of the original G915 and G915 TKL say it charges over micro-USB, and a 2026 review calls that outdated. Check the maker’s page for the G915 X charging port before buying.

What is the difference between the G915 and the G915 X?

The X generation, launched in September 2024, uses updated GL switches with cross-style stems and a slightly heavier, 22.6 mm build. The core idea of a low-profile Lightspeed, Bluetooth and wired keyboard stays the same.

Is the G613 still worth buying?

It suits buyers who want a full-height tactile board with six G-keys and a long AA battery rating. It is an older design with the heaviest weight in this group, and the sources did not address its discontinuation status.

Can I change the keycaps on the G915?

Digital Trends notes it is incompatible with most mechanical keyboard accessories, and a 2026 review says finding compatible low-profile keycaps remains challenging. A full-height board gives more choice.

Which is better for gaming, the G915 or the G613?

Both offer a 1 ms Lightspeed report rate. Tom’s Hardware credits the G915 for responsive low-profile switches, while the G613 offers macro keys and standard-height keys. The choice depends on feel and layout preference.
