You cannot replace an Apple Watch battery yourself — Apple does it for you

Apple Watch batteries are sealed inside the case and require specialized tools to open without damaging the screen or internal components. Apple does not sell replacement batteries to consumers. Instead, you send your watch to Apple or an authorized service provider, they open it, swap the battery, and seal it back up. The process takes a few days to a couple of weeks depending on where you send it and how busy the service center is.

The cost varies by watch model. Older models (Series 3 and earlier) typically cost less to service than newer ones. You can get an exact price quote before you commit by starting a repair request on Apple's website or by visiting an Apple Store in person.

Key Takeaways

  • Apple Watch batteries cannot be replaced by the owner; only Apple or an authorized service provider can open the case safely.
  • You can request a battery replacement through Apple's website, by visiting an Apple Store, or by calling Apple Support at 1-800-MY-APPLE.
  • The repair typically costs between $70 and $100 depending on your watch model, though prices vary by region.
  • The process usually takes 5 to 10 business days if you mail it in, or same-day to next-day service at some Apple Store locations.
  • If your watch is still under warranty or covered by AppleCare+, the battery replacement may be covered at no cost.

How to request a battery replacement through Apple

Start by going to support.apple.com/repair and selecting your Apple Watch model. You will be asked to describe the issue — select "Battery" or "Battery not holding charge" from the menu. Apple will show you the repair cost for your specific model and let you choose how you want to proceed.

You have three main options: mail it to Apple, visit an Apple Store, or go to an authorized service provider. If you choose mail-in service, Apple will email you a prepaid shipping label. You pack the watch in the box they provide, drop it off at a carrier location, and Apple receives it within a few days. Once they complete the repair, they ship it back to you at no extra charge.

If you have an Apple Store nearby, you can often get same-day or next-day service. Call ahead or book an appointment through the Apple Support app to avoid a long wait. Some locations keep batteries in stock; others may need to order one.

What to do before you send your watch in

Back up any data you want to keep. Your watch stores activity rings, workouts, and some app data locally. If your watch is paired to your iPhone, most of this syncs automatically to iCloud, but it is worth checking the Health app on your phone to confirm your recent activity is there.

Unpair your watch from your iPhone before you send it in. Open the Watch app on your iPhone, go to the My Watch tab, tap the watch at the top, then tap the info icon and select "Unpair Apple Watch." This removes your personal data from the device and resets it to factory settings. Apple will not do this for you, and leaving it paired can slow down the repair process.

If you have a cellular model, remove your cellular plan before sending it in. Contact your carrier to deactivate the eSIM. This step is not always required, but it prevents billing issues while your watch is in repair.

Understanding repair costs and warranty coverage

Battery replacement without a warranty typically costs $70 to $100, depending on your watch model. Newer models and larger sizes cost more. You will see the exact price when you start your repair request online.

If your watch is still under the one-year limited warranty that comes with every Apple Watch, battery replacement is covered at no cost as long as the battery failure is not due to accidental damage or liquid damage. If your watch is older than one year, you can purchase AppleCare+ for your watch, which covers battery replacement and other repairs. AppleCare+ costs between $80 and $100 depending on the model and covers two years of service from the date you buy it.

Accidental damage and liquid damage are not covered under the standard warranty or AppleCare+. If your battery failed because you dropped the watch or exposed it to water beyond its rated water resistance, you will pay the full out-of-warranty repair cost, which is higher than the standard battery replacement fee.

How long the repair takes

Mail-in service typically takes 5 to 10 business days from the time Apple receives your watch. Add 2 to 3 days for shipping each way. If you send it on a Monday, expect it back the following week or the week after.

Apple Store service is faster. Many locations can complete a battery replacement the same day if you drop it off in the morning. Some offer next-day service. Call your local store to ask about their current turnaround time, as it varies by location and how busy they are.

Authorized service providers (usually cellular carriers or electronics retailers) have varying turnaround times. Some offer same-day service; others may take a week. Ask when you contact them.

What happens if your watch is too old to repair

Apple Watch Series 1 and Series 2 models are no longer serviced by Apple. If you own one of these and the battery fails, Apple will not repair it. Your only option is to replace the watch itself.

For Series 3 and newer, Apple continues to offer battery replacement service, though parts availability can vary. If Apple determines that your watch cannot be repaired, they will offer you a discount on a new watch. The discount amount depends on your model and condition.

Alternatives if you do not want to use Apple's service

Third-party repair shops can replace Apple Watch batteries, and they are often faster and cheaper than Apple. However, opening the watch voids any remaining warranty, and the quality of the repair depends entirely on the shop. If something goes wrong during the repair, you have no recourse with Apple.

Before choosing a third-party shop, check reviews on Google and Yelp, and ask whether they use genuine Apple parts or aftermarket batteries. Aftermarket batteries may not last as long or perform as reliably as genuine ones. Some third-party shops offer a warranty on their work, which is worth asking about.

Frequently Asked Questions

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

No. Apple Watch cases are sealed with adhesive and require specialized heating and prying tools to open without cracking the screen. Attempting it yourself will almost certainly damage the watch beyond repair. The cost of a replacement screen alone exceeds the cost of professional battery service.

Will Apple replace the battery if my watch got wet?

If water damage caused the battery to fail, Apple will not cover it under warranty. You will pay the out-of-warranty repair cost, which is higher than a standard battery replacement. If the watch still powers on and the battery is straightforward old, water exposure is not relevant to the repair.

Do I need to buy AppleCare+ before I request a battery replacement?

You can buy AppleCare+ after your watch is out of warranty, but it only covers repairs from the date you purchase it forward. If your battery is already failing, buy it only if you plan to keep the watch for at least two more years and want coverage for other potential repairs.

What if I lose my watch while it is being repaired?

Apple is responsible for watches in their possession. If your watch is lost during mail-in service, Apple will replace it or refund you. Keep your shipping tracking number and the repair authorization number from your confirmation email in case you need to file a claim.

Can I use my watch while I wait for the battery replacement?

If the battery is draining quickly but still holds a charge for a few hours, you can use it normally while you wait for your repair appointment. If the battery is completely dead or drains in minutes, the watch is not usable. Either way, the repair process is the same.
