The Logitech MX Mechanical at $159.99 (logitech.com, 2026-09-06, in stock) is the pick for work: up to 15 days of battery with the backlight on and roughly 10 months with it off, from a 1500mAh cell, over Logi Bolt or Bluetooth LE. For office use the axis that matters is battery life and multi-device switching, not report rate, which is why that figure decides it. The Keychron V5 Max ($109.99, keychron.com, unchanged across the 2026-08-26 and 2026-09-06 checks, in stock on both) is the value runner-up: $50.00 cheaper, full tri-mode with a 2.4GHz option and wired USB-C, plus QMK/VIA and hot-swap the MX Mechanical lacks — but its 4000mAh battery only rates up to 190h with backlight off, far short of the MX's figure, because RGB and a busier radio stack draw much more power than the MX's simple white LED and proximity sensor. Caveats: no battery figure here was measured by us, Logitech quotes days and months of typical use where Keychron and NuPhy quote continuous bench hours, every figure is a manufacturer specification read on the date given, and prices and stock change without notice.
The limits first: no runtime here was measured by us and Logitech's figures are quoted in days and months of typical use where the others are continuous bench hours, every figure below is a manufacturer specification read on the date given, and prices and stock are the 2026-09-06 re-check unless a line names 2026-08-26. For office use, report rate barely matters — 90Hz Bluetooth is invisible for word processing and email — so the deciding factors are how rarely you charge and how cleanly the board moves between a laptop, a desktop, and a tablet.
The Logitech MX Mechanical is built for exactly that: Bluetooth LE or a Logi Bolt 2.4GHz receiver, a hand-proximity sensor and ambient-light sensor that only light the backlight when you're at the keyboard, and battery ratings of up to 15 days backlit or about 10 months with backlight off from a 1500mAh cell. The trade-off is real: USB-C on this board is charging only, with no wired data mode, so there is no fallback if the wireless connection ever misbehaves, and it has one fixed switch type per SKU with no hot-swap.
The Keychron V5 Max covers the same office duty for $109.99 and adds what the MX Mechanical doesn't: a genuine 2.4GHz radio (1000Hz) alongside Bluetooth 5.1 and wired USB-C, QMK/VIA firmware, hot-swap sockets, and a rotary knob. Its 4000mAh battery is nearly three times the MX Mechanical's capacity, yet its own rated figure — up to 190h with backlight off, 100h RGB at lowest brightness — is a small fraction of the MX's ~10 months. Bigger capacity does not mean longer runtime; LED design and always-on radio scanning matter more, and the V5 Max also drops to 90Hz the moment you switch it to Bluetooth mode.
The NuPhy Halo75 V2 (A$229.00, nuphy.com.au, 2026-09-06 — an Australian-dollar figure at an Australian store, not comparable to the US-dollar prices above, and out of stock there on that date) sits between them: up to 307h with backlight off (a NuPhy lab figure) from its own 4000mAh cell, 3/5-pin MX-style hot-swap, but only 125Hz over Bluetooth — the lowest of the three. This comparison is not for gamers chasing report rate (all three fall to 90-125Hz over Bluetooth) and not for anyone who needs a wired-data fallback if wireless drops — only the V5 Max and Halo75 V2 offer one; the MX Mechanical does not.
