What will you mostly use it for?
The layout difference dictates the winner for most use cases. The B35's 96% layout with a number pad wins for office work and content creation. The B31's compact 75% form is better for gaming and travel where space is at a premium. For programming and modding, the keyboards are evenly matched, as they share the same core typing experience and customization limitations.

Keychron B31 vs B35: your questions
The main difference is the layout size. The B31 is a 75% keyboard, which omits the number pad and some navigation keys for a compact footprint. The B35 is a 96% keyboard, which includes a number pad and arrow keys in a condensed layout that is longer than the B31.
No. According to the specifications listed on the vendor pages, both the Keychron B31 and B35 are not hot-swappable. This means you cannot physically replace the scissor switches without soldering.
The Keychron B31 product description explicitly states its ABS keycaps are not replaceable. While not explicitly stated for the B35, both keyboards use a unique scissor switch mechanism, making it unlikely standard mechanical keyboard keycaps will be compatible.
No. Both the Keychron B31 and B35 are listed as non-backlit in their specifications. They do not feature any form of key lighting.
Both keyboards are equipped with an 800mAh rechargeable battery. Keychron states they can deliver up to 320 hours of continuous use on a single charge based on lab tests, though actual battery life will vary with usage.
Both keyboards support a 1000 Hz polling rate when using the 2.4 GHz wireless dongle or the wired USB-C connection. When connected via Bluetooth, the polling rate is 125 Hz.
Yes. Both keyboards have a system toggle switch to change between Windows and macOS layouts. Furthermore, the Keychron Launcher web app for customization is compatible with macOS, Windows, and Linux.
Both keyboards use a scissor switch mechanism, not traditional mechanical switches. Keychron describes them as having an innovative design that is 59% taller than standard scissor switches, with pre-lubed keys for a silent and smooth typing experience.
Customization is done through the Keychron Launcher, a web-based app. It allows for key remapping, creating macros, and setting up shortcuts. The Launcher works in browsers like Chrome, Edge, and Opera and does not require software installation.
The Keychron B31 is better for a small desk due to its 75% layout. With a length of 327mm, it takes up significantly less space than the 381mm long B35, freeing up valuable room for your mouse and other peripherals.
The product descriptions and specifications do not mention an included wrist rest. Both keyboards feature adjustable typing angles (5°, 6.5°, 9°) for ergonomic support instead.
Both the Keychron B31 and B35 have a magnetic storage slot, located at the top right corner of the keyboard, where you can store the USB Type-A receiver when not in use.
