Why Your Apple Watch Battery Drains So Quickly
Several settings, apps, and background activities can cause your Apple Watch battery to drain faster than expected.
1. Always-On Display Uses More Power
The Always-On Display keeps your screen active all day. While convenient, it constantly uses battery power.
This feature affects battery life more on older Apple Watch models.
How to Turn Off Always-On Display
- Open Settings
- Tap Display & Brightness
- Tap Always On
- Turn it off
This single change can noticeably improve battery life.
2. Too Many Notifications Wake the Screen
Every notification lights up the display and activates the watch. Hundreds of alerts per day can drain your battery quickly.
Common battery-draining notifications include:
- Social media apps
- News alerts
- Shopping apps
- Email sync
- Messaging apps
How to Reduce Notifications
- Open the Watch app on iPhone
- Tap Notifications
- Disable unnecessary apps
Focus only on important alerts.
Background Apps May Be Running Constantly
Some apps continue updating in the background even when you are not using them.
This includes:
- Weather apps
- Fitness apps
- Music streaming apps
- Stock trackers
Turn Off Background App Refresh
- Open Settings
- Tap General
- Tap Background App Refresh
- Disable apps you do not need
You can also turn the feature off completely.
GPS and Workouts Drain Battery Faster
Workout tracking uses GPS, heart rate sensors, and motion tracking at the same time.
Activities that use the most battery include:
- Outdoor running
- Cycling
- Hiking
- Navigation
Long workouts can significantly reduce battery life.
Tips to Save Battery During Workouts
- Lower screen brightness
- Download music instead of streaming
- Turn off cellular if not needed
- Use Power Saving Mode
Enable Workout Power Saving Mode
- Open Settings
- Tap Workout
- Turn on Power Saving Mode
This reduces heart rate sensor usage during walking and running workouts.
Poor Cellular or WiFi Signal Causes Battery Drain
When your Apple Watch struggles to find a signal, it uses more power trying to stay connected.
This happens often in:
- Basements
- Rural areas
- Elevators
- Buildings with thick walls
Quick Fixes
- Turn on Airplane Mode in weak-signal areas
- Use WiFi instead of cellular when possible
- Keep your iPhone nearby
Outdated watchOS Can Cause Battery Problems
Software bugs sometimes cause abnormal battery drain.
Apple regularly fixes these issues in watchOS updates.
How to Update Apple Watch
- Open the Watch app on iPhone
- Tap General
- Tap Software Update
- Install available updates
Keep both your iPhone and Apple Watch updated.
Battery Health May Be Degraded
Like all rechargeable batteries, Apple Watch batteries wear out over time.
Older batteries hold less charge and drain faster.
How to Check Apple Watch Battery Health
- Open Settings
- Tap Battery
- Tap Battery Health
If Maximum Capacity is below 80%, battery performance may be reduced.
Third-Party Apps Can Drain Battery
Some apps are poorly optimized and constantly run in the background.
Battery-draining apps often include:
- Streaming apps
- Fitness trackers
- Navigation apps
- Messaging apps
How to Find Problem Apps
Check battery usage after installing a new app. If the issue started recently, remove the newest apps first.
Remove Unused Apps
- Press the Digital Crown
- Find the app
- Hold the app icon
- Tap delete
Screen Brightness Affects Battery Life
A brighter display uses more battery power.
Lower Apple Watch Brightness
- Open Settings
- Tap Display & Brightness
- Reduce brightness
Even one level lower can help.
Raise to Wake Can Drain Battery
Raise to Wake turns the screen on every time you move your wrist.
Frequent wrist movement means more battery usage.
Turn Off Raise to Wake
- Open Settings
- Tap Display & Brightness
- Tap Wake
- Disable Wake on Wrist Raise
Bluetooth, WiFi, and Cellular All Use Power
Keeping every wireless feature enabled all day increases battery drain.
Best Practice
Use only the connections you actually need.
For example:
| Feature | When to Turn Off |
|---|---|
| Cellular | When iPhone is nearby |
| WiFi | When not connected |
| Bluetooth | Rarely disable unless troubleshooting |
