Check Apple Watch Battery Health and When It Should Be Replaced

Is your Apple Watch no longer lasting throughout the day? Before you take it in to trade it or get it repaired, it's worth checking your Apple Watch battery health. This will help you decide if it's time to have your battery replaced so your watch is running at its best and your trade-in value is maximized.

Why Apple Watch Battery Health Matters

The Apple Watch contains a lithium-ion battery that will degenerate over time and cause:

Decreased battery life
Random shutdowns
Slower performance

Checking your battery capacity will give you an understanding of the condition of your watch before a trade-in, resale, or repair. If the battery health of your Apple Watch is low, replacement can significantly extend the life of your device.

How to Check Apple Watch Battery Health

Checking your Apple Watch battery health is a breeze:

Press the Digital Crown and open the Settings app.
Tap Battery.
Tap Battery Health.
Take a look at the maximum capacity shown.
- - 100% - 85%: Healthy battery
  - 84% - 80%: Monitor this; consider replacing if battery life is poor
  - Below 80%: Apple Watch battery time to replace

Tip: You can also enable Optimized Battery Charging here to slow down battery aging.

When to Replace Your Apple Watch Battery

You may want to replace Apple Watch batteries if:

Your battery health is below 80%
Your watch dies before the day ends
You experience unexpected shutdowns
You plan to trade in and want maximum value

Most Apple Watch batteries decline to 80% within 2-3 years of daily use. Replacing your battery can refresh your device at a lower cost than buying a new watch.

How to Make Your Apple Watch Battery Last Longer

Prior to replacing, use the following tips to enhance battery life:

Turn on Low Power Mode when necessary
Limit Always-On Display usage
Turn off Background App Refresh
Install the latest watchOS
Avoid frequent full discharges

These are habits that lower battery wear and tear and make your Apple Watch last longer.
