Can I swap the switches on the G915 X later?

No. The GL switches are fixed at the factory and are not hot-swappable, so the switch type you buy (Tactile, Linear, or Clicky) is permanent.

Does the full-size and TKL version have the same battery life?

No, Logitech rates them differently: the full-size is rated up to ~800 hours (lighting off) and ~36 hours (full RGB on LIGHTSPEED), while the TKL is rated up to ~1,000 hours and ~42 hours respectively.

Logitech G915 X LIGHTSPEED: What to Know

The configuration verified here is the full-size G915 X LIGHTSPEED in Black with GL Tactile switches. Logitech's low-profile GL switches sit at a 1.3mm actuation point with 3.2mm of total travel, which is noticeably shorter than the roughly 4mm travel of a standard mechanical switch like the ones in the Keychron or Razer boards below, and is the main reason this keyboard has a slim, low-desk-clearance profile rather than a tall, chunky one.

Connectivity is tri-mode: Logitech's proprietary LIGHTSPEED 2.4GHz wireless, Bluetooth, or wired USB-C. Logitech's official battery figures differ by keyboard size: the full-size G915 X is rated up to about 800 hours with backlighting off and up to about 36 hours of continuous use at 100 percent RGB brightness over LIGHTSPEED, while the separate tenkeyless (TKL) version of the same line is rated higher, at up to 1,000 hours lighting-off and 42 hours at full brightness. We're calling that out because it's easy to see the TKL model's numbers online and assume they apply to the full-size board.

One notable gap compared to several other boards in this guide: the G915 X's switches are not user hot-swappable. They're fixed per SKU, so the Tactile, Linear, and Clicky variants are separate products rather than something you can change after purchase, though Logitech does use a standard Cherry-style stem so aftermarket low-profile keycaps are compatible.

The rest of the feature set is aimed squarely at a hybrid gaming/work desk: a brushed aluminum top plate, double-shot PBT keycaps (more durable against shine than the ABS keycaps on some gaming boards), LIGHTSYNC RGB with roughly 16.8 million colors, nine programmable G-keys, dedicated media controls, and a volume roller.
