Apple Watch battery health
Every refurbished Apple Watch we sell has a battery at 80% or better. Here’s what that means and how to look after it.
What “battery health 80%+” means
Just like iPhone, Apple Watch battery health is a percentage that compares the current capacity to brand-new. 100% is as-new; 80% means it holds 80% of the original charge. Below 80% you notice the Watch not lasting a full day.
We test every Watch during refurbishment — anything under 80% gets a new battery before it can be sold.
How to check your Watch’s battery health
- On your Watch, open Settings → Battery.
- Tap Battery Health.
- Look at Maximum Capacity.
Only available on Apple Watch Series 4 and later, running watchOS 7 or later. Older models don’t show the percentage.
Battery warranty
Batteries are covered for 6 months from delivery (the Watch itself is covered for 12). If Maximum Capacity drops below 80% in the first 6 months, we’ll replace the battery free.
After 6 months, batteries fall outside warranty. We can quote for a paid battery service through Apple’s service network.
Looking after your Watch’s battery
- Use the magnetic charging puck that came in the box — third-party fast chargers can stress the battery.
- Don’t leave the Watch in a hot car or direct sunlight.
- Take it off the charger when full — sitting at 100% for hours accelerates wear.
- If you don’t need Always-On Display, turn it off. It’s the single biggest battery user on most Watches.
