Apple will replace your battery, but you cannot do it yourself

You cannot open an Apple Watch and replace the battery on your own. Apple Watch models are sealed devices — the back is glued shut and contains no user-accessible parts. If your battery no longer holds a charge, your only option is to send the watch to Apple or visit an Apple Store for a battery replacement.

Apple charges a flat fee for this service regardless of which model you own. The cost is typically $79 for the battery replacement itself, plus $6.95 for shipping if you mail it in. Some Apple Stores may charge slightly different amounts depending on your location, so calling ahead is worth doing.

The entire process usually takes 5 to 7 business days if you mail the watch to Apple, or 1 to 2 hours if you have an Apple Store nearby and can drop it off in person. During this time, you will not have access to your watch.

Key Takeaways

  • Apple Watch batteries are not replaceable by the user because the watch is sealed with glue and contains no removable parts.
  • Apple charges $79 for battery replacement plus $6.95 shipping if you mail the watch, or you can visit an Apple Store for same-day or next-day service.
  • The repair takes 5 to 7 business days by mail or 1 to 2 hours at a physical store.
  • If your watch is still under warranty or covered by AppleCare+, the battery replacement may be covered at no cost.

When your Apple Watch battery stops holding a charge

Apple Watch batteries degrade over time with normal use. Most Apple Watch batteries are designed to retain about 80 percent of their original capacity after 1,000 charge cycles. A charge cycle is one full discharge and recharge, so this typically happens after 2 to 3 years of daily use.

You will notice the battery draining faster than it used to, or the watch shutting down even when the battery indicator shows charge remaining. At this point, the battery has degraded enough that replacement makes sense. Continuing to use a degraded battery will not damage the watch, but you will lose the ability to wear it for a full day without charging.

How to start a battery replacement with Apple

You have two paths: mail the watch to Apple, or visit an Apple Store in person. To mail it in, go to apple.com/support, select your watch model, and choose the battery service option. You will receive a prepaid shipping label and instructions for packing the watch safely. Apple will inspect it, replace the battery, test it, and ship it back to you.

If you have an Apple Store nearby, you can make a Genius Bar appointment through the Apple Support app or by calling the store directly. Bring your watch and your proof of purchase if possible. The technician will inspect the battery, confirm it needs replacement, and either do the work while you wait or order the part if it is not in stock that day.

Before you send the watch in, back up any data you want to keep by syncing it with your iPhone. The battery replacement itself will not erase your data, but it is good practice to have a backup.

What AppleCare+ covers for battery replacement

If you purchased AppleCare+ for your watch, battery replacement is covered at no cost as long as the watch is still within the AppleCare+ period. AppleCare+ typically lasts 2 years from the date you buy it and covers accidental damage, hardware failures, and battery service.

If your watch is still within the original 1-year limited warranty but you did not buy AppleCare+, Apple will replace the battery at no cost only if the battery has failed due to a manufacturing defect — not normal wear. This is rare. In most cases, you will pay the $79 fee.

To check whether your watch is covered, open the Apple Support app, select your watch, and look at the coverage details. You can also call Apple Support at 1-800-MY-APPLE and provide your serial number.

Third-party repair shops and why they are risky

Some independent repair shops advertise Apple Watch battery replacement for less than Apple's $79 fee. These shops must break the seal on the back of the watch to access the battery, which requires heat, prying tools, and careful handling. If the seal is not properly resealed, water can enter the watch and damage the internal components.

Apple Watch models are water-resistant, not waterproof. That water resistance depends on the seal being intact. Once an independent shop opens the back, the watch's water resistance rating is no longer may provide, even if the shop claims to reseal it properly. You also lose any remaining warranty coverage.

If you choose to use a third-party shop, understand that you are accepting the risk of water damage and losing Apple's support. For most people, the extra cost of going through Apple is worth the assurance that the repair is done correctly and the watch remains water-resistant.

Extending battery life before replacement becomes necessary

You can slow down battery degradation by adjusting how you charge and use your watch. Avoid letting the battery drop to zero percent regularly — instead, charge it when it reaches 20 percent. Avoid leaving the watch plugged in and charging overnight every night; charge it during the day and unplug it when full.

In the watch settings, turn off features you do not use regularly, such as always-on display, background app refresh, or continuous heart rate monitoring. These features drain the battery faster and cause more charge cycles, which speeds up degradation. Keeping the watch software up to date also helps, since Apple sometimes releases updates that improve battery efficiency.

Even with these steps, the battery will eventually degrade. These practices simply slow the process and give you more time before you need to pay for replacement.

Frequently Asked Questions

How much does it cost to replace an Apple Watch battery?

Apple charges $79 for battery replacement plus $6.95 for return shipping if you mail the watch in. If you visit an Apple Store in person, you pay $79 and do not pay shipping. If you have AppleCare+ and it is still active, the replacement is covered at no cost.

Can I replace the battery myself with a kit from the internet?

You can buy battery replacement kits online, but opening an Apple Watch requires specialized tools and skill. If you damage the seal, the watch will lose its water resistance. If you damage internal components, the watch may stop working entirely. Apple's $79 service is usually cheaper than the cost of replacing a damaged watch.

What happens to my data when Apple replaces the battery?

Battery replacement does not erase your data. Your watch will still have all your apps, settings, and activity history after the repair. However, it is good practice to sync your watch with your iPhone before sending it in, just in case.

How long does battery replacement take at an Apple Store?

If the store has the battery in stock, the replacement takes 1 to 2 hours. If the battery is not in stock, the technician will order it and you will need to return to the store or have it shipped to you. Calling ahead to ask about stock can save you a trip.

Will my Apple Watch still be water-resistant after Apple replaces the battery?

Yes. Apple uses the same sealing process for battery replacement that was used when the watch was manufactured. Your watch will maintain its original water-resistance rating after the repair.
