I do most of my daily work on my 24-inch iMac and I have several bluetooth accessories—a Magic Mouse, Magic Keyboard, Magic Trackpad, AirPods Max, and a DUALShock Wireless Controller. It’s a pain in the butt when I’m working (or playing) and a peripheral is suddenly running low on juice.
I’ve made it a habit to check my accessories’ power levels at least once a month. There’s little point in checking them more often as most will run for weeks when fully charged. (The exception is the AirPods Max, which can get up to 20 hours of listening time, talk time, or film playback when you have Active Noise Cancellation and spatial audio turned on.)

You should probably set up a similar battery level check routine. There are two ways to check the amount of juice per device with macOS:
° Go to System Preferences > Bluetooth.
° You’ll see all your Bluetooth devices and a graphic illustrating their power level. (You’ll also see whether or not the accessories are connected via Bluetooth.)
For more details, go back to System Preferences and choose the Keyboard, Mouse, or Trackpad panes. Now you can see, among other useful information the exact percentage level of each device.
You can also quickly check the battery levels of your Bluetooth devices by going to the menu bar at the top of your Mac’s screen and clicking the Bluetooth icon.
You’ll see the names of all your Bluetooth peripherals and the percentage of battery power the ones connected via Bluetooth are packing.
