Is your Apple Watch 4 lagging, freezing, or just taking forever to respond? A slow smartwatch can be incredibly annoying, especially when you rely on it for quick glances and seamless performance. Whether the slowdown started after a watchOS update, app install, or seemingly out of nowhere, here’s how to get your Apple Watch 4 running fast again.
Check Your Storage First
Before anything else, check how much free space your watch has. Go to the Watch app on your iPhone > General > About and see how much storage is available. If it’s under 1GB, that’s likely the culprit—clear out unused apps, music, or photos to free up space.
1. Restart or Force Restart Your Watch
A simple reboot can clear temporary bugs and refresh your watch’s memory.
To restart (soft reset):
- Press and hold the Side button until the power slider appears.
- Drag the slider to turn off the watch.
- After 30 seconds, press and hold the Side button again until the Apple logo shows up.
If your watch is frozen:
- Press and hold both the Side button and Digital Crown for at least 10 seconds, until you see the Apple logo.
2. Reduce Motion (Turn Off Animations)
Too many visual effects can slow down your Apple Watch.
To reduce motion:
- Open the Settings app on your watch.
- Go to General > Accessibility.
- Turn Reduce Motion on.
This disables fancy animations and can instantly make your watch feel snappier.
3. Update Your Watch and Apps
Outdated software or apps can cause performance issues. Make sure everything is up to date.
To update watchOS:
- Open the Watch app on your iPhone.
- Go to My Watch > General > Software Update.
- Download and install any available update (your watch must be on the charger and connected to Wi-Fi).
To auto-update apps:
- In the Watch app on your iPhone, go to My Watch > General.
- Turn on Automatic App Install.
4. Delete Unused or Problematic Apps
Bad or bloated apps can slow your system down—especially if they’re misbehaving after an update.
To remove apps from your watch:
- Open the Watch app on your iPhone.
- Tap My Watch, then scroll to the app you want to remove.
- Tap the app and toggle off Show App on Apple Watch.
Repeat this for any apps you no longer use or suspect might be causing problems.
5. Factory Reset and Set Up as New
If the lag continues after everything else, a clean slate might help. This will erase all data and settings, so make sure to back up your watch first.
To erase your Apple Watch:
- On the watch, go to Settings > General > Reset.
- Tap Erase All Content and Settings.
- Choose whether or not to keep your cellular plan.
- Tap Erase All to confirm.
Once done, set it up as new instead of restoring from backup. That way, you avoid reintroducing the same problem.
Still Slow? Time for a Hardware Check
If your Apple Watch 4 is still sluggish after all these fixes, it might be a hardware issue—especially if it’s been dropped, exposed to moisture, or experiencing battery-related symptoms. Book an appointment with an Apple Store or authorized repair center to get it checked out.
