You’re on a Microsoft Teams call, trying to type something quickly—and suddenly your Bluetooth keyboard lags, skips, or even double-enters keys. It’s frustrating. Worse, it only seems to happen during calls.
This isn’t random. It’s a common issue tied to how your device handles Bluetooth, CPU load, and real-time video processing. The good news? You can fix it fast.
Quick Fix (Try This First)
- Turn Bluetooth OFF and back ON
- Move your keyboard closer to your device
- Close unused apps running in the background
- Switch Teams video OFF temporarily
- Reconnect the keyboard (forget → pair again)
Try this first. In many cases, this usually fixes it instantly.
Why This Happens
Here’s the short answer:
Bluetooth keyboard lag or double typing during Teams calls happens because your device is overloaded handling video, audio, and Bluetooth signals at the same time.
When CPU or Bluetooth bandwidth gets tight, keystrokes can get delayed, repeated, or dropped.
This usually happens after updates or when using wireless devices together (like headphones + keyboard). Most people don’t notice it until they’re on a video call.
Here’s what’s going on behind the scenes:
- Teams video calls consume high CPU and RAM
- Bluetooth shares bandwidth across devices
- Interference increases when Wi-Fi + Bluetooth run together
- Input buffering causes delayed or repeated keystrokes
This is where things get tricky—because it’s not just one issue. It’s a combination.
Step-by-Step Fixes
Reduce System Load (Most Effective Fix)
If your device struggles during calls, your keyboard is the first thing to glitch.
- Turn off video if not needed
- Close Chrome tabs or heavy apps
- Disable background sync apps (Dropbox, Google Drive)
This usually fixes it instantly on mid-range devices.
Reconnect Your Bluetooth Keyboard Properly
Most people skip this step—but it matters.
- Go to Bluetooth settings
- Remove (forget) the keyboard
- Restart your device
- Pair the keyboard again
This clears corrupted pairing data that can cause double typing.
Disable Bluetooth Power Saving
On many devices, Bluetooth goes into low-power mode during heavy usage.
Windows:
- Open Device Manager
- Find Bluetooth adapter
- Go to Power Management tab
- Uncheck “Allow the computer to turn off this device”
This is one of the most overlooked causes.
Switch Wi-Fi Band (Reduces Interference)
Bluetooth and Wi-Fi can interfere—especially on 2.4 GHz.
- Switch to 5 GHz Wi-Fi if available
- Move away from routers or crowded networks
You’ll often notice typing becomes instantly smoother.
Update Teams and System Drivers
This usually happens after updates—but sometimes updates fix it too.
- Update Microsoft Teams
- Update Bluetooth drivers (Windows/macOS)
- Restart after updates
Device-Specific Fixes
On Windows PC
- Disable “Enhance Pointer Precision” (yes, it affects input timing)
- Check Task Manager → CPU usage during calls
- Use USB Bluetooth dongle if built-in adapter is weak
On Mac
- Reset Bluetooth module (Shift + Option → Bluetooth menu)
- Disconnect extra Bluetooth devices
- Keep macOS updated
On Android / iPad
- Turn off battery optimization for Teams
- Disable keyboard auto-correction temporarily
- Forget and reconnect Bluetooth keyboard

If It Still Doesn’t Work
Now we’re into less common causes.
- Keyboard battery is low (causes unstable signal)
- Too many Bluetooth devices connected at once
- Cheap Bluetooth keyboards with poor buffering
- USB 3.0 interference (yes, this is real)
In some cases, switching to a wired keyboard immediately solves everything.

Extra Tips to Prevent This Issue
- Keep keyboard battery above 30%
- Avoid using too many wireless devices at once
- Restart your device before important calls
- Use 5 GHz Wi-Fi whenever possible
- Keep your OS and apps updated
Small habits make a big difference here.
FAQ
Why does my Bluetooth keyboard double type only on Teams?
Because Teams uses high CPU and network resources, which can delay Bluetooth input and cause repeated keystrokes.
Does turning off video help keyboard lag?
Yes. Disabling video reduces system load and often fixes keyboard lag instantly.
Is this a keyboard problem or a system problem?
Usually a system performance and Bluetooth interference issue—not the keyboard itself.
Can Wi-Fi affect Bluetooth keyboard performance?
Yes. Especially on 2.4 GHz networks, interference can cause lag and input errors.
Should I switch to a wired keyboard?
If the issue persists, yes—it’s the most stable solution during video calls.
