- Bluetooth Low Energy (BLE): Allows wireless connection to computers with built-in Bluetooth. The mouse can maintain connections with up to 3 Bluetooth devices.
Unifying Receiver Pros
- More stable connection
- Lower latency (1-2ms vs 8-15ms for Bluetooth)
- Works with older computers without Bluetooth
- Supports Logitech Flow for seamless cross-computer control
Bluetooth Pros
- No USB port required
- Works with tablets and smartphones
- Easier to switch between devices
- Lower power consumption in standby

Advanced Configuration and Optimization
For power users who want to maximize their MX Master 2S experience across two computers, these advanced tips will help optimize performance, battery life, and functionality:
1. Customizing Button Assignments Per Device
The MX Master 2S allows different button configurations for each connected device:
- Open Logitech Options on the computer you want to customize
- Select your MX Master 2S from the device list
- Go to the “Buttons” tab
- Choose which button you want to customize
- Select an action from the dropdown menu (or create a custom gesture)
- Repeat for each button you want to customize
- Switch to your other computer and repeat the process for device-specific configurations
Recommended Button Configurations
| Button | Windows PC | Mac | iPad |
|---|---|---|---|
| Thumb Wheel | Horizontal Scroll | Mission Control | Volume Control |
| Gesture Button | App Switcher | Expose | Home Screen |
| Middle Click | Middle Click | Middle Click | Spotlight Search |
| DPI Shift | Precision Mode | Precision Mode | Zoom In/Out |
2. Optimizing Battery Life
The MX Master 2S has impressive battery life (up to 70 days on a full charge), but connecting to multiple devices can reduce this. Here’s how to maximize battery performance:
- Use Smart Sleep: Enable in Logitech Options to put mouse to sleep when not in use
- Adjust Polling Rate: Lower to 500Hz when not gaming (in Logitech Options > Performance)
- Disable Unused Features: Turn off gesture button if not using
- Use Wired Mode When Possible: Connect via USB for charging while using
- Update Firmware: Newer versions often include battery optimizations
- Connection Management: Disconnect from unused devices via Easy-Switch button
3. Troubleshooting Common Issues
Even with proper setup, you might encounter issues when using the MX Master 2S with two computers. Here are solutions to the most common problems:
Common Issues and Solutions
| Issue | Possible Cause | Solution |
|---|---|---|
| Mouse not switching between computers | Easy-Switch button not working | Hold button for 5 seconds to reset, then re-pair |
| High latency on one computer | Bluetooth interference | Switch to Unifying Receiver or change Bluetooth channel |
| Logitech Flow not working | Computers not properly positioned | Recalibrate in Logitech Options > Flow |
| Battery draining quickly | Multiple active connections | Disable unused connections via Easy-Switch |
