Your wireless Razer mouse's battery level in the Windows tray, without Razer Synapse.
- Installation: download, first start, start at login, updates, and uninstall.
- Using the tray: the icon colors, the menu, and how often razertray checks the battery.
- Low-battery notifications: when alerts appear and how to change them.
- Configuration: every setting in
config.toml, and the other files razertray keeps. - Supported devices: which mice razertray knows, and what happens with other Razer devices.
- Troubleshooting: no device found, no notifications, and where to find the log.
- Development: build from source, checks, and the device list generator.
- Battery in the tray: a small battery icon fills up and changes color: green, orange at 35% or less, red at 15% or less, and blue while charging.
- Percentage as text: show the exact number as colored digits instead of the battery.
- Low-battery alerts: a Windows notification when a mouse drops to 15% or less, repeated at most every two hours per device.
- Several devices: see every connected Razer device in the menu and pick the one the icon tracks.
- Known by name: 66 Razer mice and wireless receivers, from the OpenRazer device list. Newer mice still get a reading under their system name.
- Quiet and small: one portable
.exe, no installer, no background service, and no Razer software. - Start at login: turn it on from the tray menu.
razertray needs Windows 10 or 11 and a Razer mouse that is connected by cable or through its wireless receiver.
- Download
razertray.exefrom the latest release. - Move it to a folder where it can stay, for example
%LOCALAPPDATA%\Programs\razertray. - Double-click it. razertray has no window. A battery icon appears in the notification area next to the clock. If you cannot see it, open the hidden icons with the arrow (^) next to the clock.
- Hover over the icon to see the mouse name and the battery percentage. Right-click it for the menu.
- Optional: select Start at login in the menu, so razertray starts each time you sign in to Windows.
The first reading can take a few seconds. If the icon shows a gray x, see Troubleshooting.
razertray asks the mouse for its battery level directly over USB, with the same commands that the OpenRazer Linux driver uses. It checks once a minute and keeps everything on your computer: it has no account, no network access, and no telemetry.
- GitHub Issues: bug reports and feature requests. Please attach the log file; see Troubleshooting.
