Apple Watch batteries can be replaced, but not by you — Apple or an authorized repair shop must do it

The battery in your Apple Watch is glued to the case and soldered to the logic board. There is no user-accessible battery compartment. If your watch no longer holds a charge through the day, you have two paths: send it to Apple for a battery replacement, or take it to an Apple Authorized Service Provider. Both involve opening the watch with specialized tools and replacing the entire battery unit.

The cost and timeline depend on which route you choose and whether your watch is still under warranty. Out-of-warranty battery replacement at Apple typically costs between $70 and $100, though the exact price varies by watch model and your location. The process usually takes 3 to 5 business days if you mail it in, or same-day to next-day service if you visit an Apple Store in person.

Key Takeaways

  • Apple Watch batteries are permanently glued and soldered into the case, so opening the watch yourself will damage it beyond repair.
  • Apple and Apple Authorized Service Providers can replace the battery by opening the case with specialized equipment.
  • Out-of-warranty battery replacement costs $70 to $100 depending on your watch model and location.
  • If your watch is under warranty or covered by AppleCare+, the replacement may be free or cost only the service fee.
  • Mail-in service takes 3 to 5 business days; in-store service at an Apple Store is often same-day or next-day.

Why you cannot open an Apple Watch yourself

The Apple Watch case is sealed with a strong adhesive that requires heat and specialized prying tools to remove without cracking the glass or damaging the aluminum frame. Once open, the battery is soldered directly to the main circuit board — it is not a plug-in component. Removing it requires a soldering station and desoldering equipment that most people do not own.

Attempting to open the watch yourself will almost certainly crack the screen or bend the case. Even if you succeed in removing the old battery, you will likely damage the logic board in the process. At that point, the watch is no longer repairable — Apple will not replace a board that was damaged by unauthorized repair, and the cost of a new board exceeds the cost of a replacement watch.

Getting a battery replacement through Apple

You can start a battery replacement by visiting an Apple Store, calling Apple Support at 1-800-MY-APPLE, or starting a repair request on Apple's website. If you go to a store, bring your watch and your receipt or proof of purchase if you have it. The Genius Bar will run a diagnostic to confirm the battery is the problem — sometimes what feels like a dead battery is actually a software issue that a restart can fix.

If the battery is confirmed faulty and your watch is under the one-year limited warranty, the replacement is free. If you have AppleCare+ for your watch, battery service is covered at no cost. If your watch is out of warranty and you do not have AppleCare+, you will pay the out-of-warranty service fee, which ranges from $70 to $100 depending on the model.

For mail-in service, Apple will send you a prepaid shipping label. You pack the watch, drop it off, and Apple processes it at a repair facility. Turnaround is typically 3 to 5 business days from the time Apple receives it, not including shipping time. In-store service is faster — many Apple Stores can replace the battery same-day or next-day if they have the part in stock.

Using an Apple Authorized Service Provider

If you do not have an Apple Store nearby, an Apple Authorized Service Provider can replace your battery. These are independent repair shops that Apple has certified and supplied with genuine parts and training. You can find one near you by visiting Apple's service locator on their website or calling Apple Support for a referral.

Authorized Service Providers charge the same out-of-warranty rates as Apple — $70 to $100 — and honor the same warranty coverage. Turnaround time varies by location but is often faster than mail-in service because you can drop off and pick up locally. Call ahead to confirm they have the battery in stock for your specific watch model, as some smaller shops may need to order it.

What to do if your watch is still under warranty

If you bought your Apple Watch less than one year ago, the battery is covered under Apple's limited warranty as long as the battery failure is not caused by physical damage or liquid damage. Bring your watch and proof of purchase to an Apple Store or Authorized Service Provider. They will run a diagnostic to rule out physical or water damage, and if the battery is straightforward worn out, the replacement is free.

If your watch has been dropped, cracked, or exposed to water and the battery is failing, Apple may classify it as damage-related rather than a manufacturing defect. In that case, you may be charged the out-of-warranty rate even though the watch is within the one-year window. AppleCare+ covers accidental damage, so if you have that plan, battery replacement is still free.

AppleCare+ and battery coverage

AppleCare+ for Apple Watch extends coverage to two years from the date of purchase and covers battery service at no cost. It also covers accidental damage like drops and water damage, with a small service fee per incident ($0 to $99 depending on the damage). If you are considering AppleCare+, you must purchase it within 60 days of buying the watch.

If you already have AppleCare+ and your battery is failing, battery replacement is free — you pay nothing. You can start the service request the same way you would for a standard warranty repair. AppleCare+ is optional and costs extra, but if you plan to keep your watch for two years or longer, it can save money on battery and accidental damage repairs.

Signs your Apple Watch battery needs replacement

A failing battery usually shows itself in one of three ways: the watch drains from full charge to empty in a few hours instead of a full day, the watch shuts down at 20 or 30 percent battery even though the battery indicator shows more charge remaining, or the watch will not turn on at all even after charging overnight.

Before you assume the battery is dead, try a force restart. Hold the side button and the Digital Crown together for 10 seconds until you see the Apple logo appear. If the watch restarts and holds a charge normally, the battery was fine — it just needed a restart. If the problem returns within days, or if the watch still will not turn on after a restart, the battery likely needs replacement.

Frequently Asked Questions

How long does an Apple Watch battery last before it needs replacement?

Apple Watch batteries are designed to retain 80 percent of their original capacity after 1,000 charge cycles, which typically takes 2 to 3 years of normal daily use. Most people notice the battery draining faster around year 2 or 3. If you charge your watch every night, you will likely need a replacement sometime in the third year of ownership.

Can I replace just the battery, or does Apple replace the whole watch?

Apple replaces only the battery, not the entire watch. The cost is the service fee ($70 to $100 out of warranty), not the cost of a new watch. If the watch has other damage — a cracked screen or water damage — those are separate repairs with separate costs.

What happens if I try to replace the battery myself and break the watch?

Apple will not repair a watch that was opened by someone other than an authorized technician. If you crack the screen or damage the logic board while trying to replace the battery, you will need to buy a replacement watch. The repair cost will exceed the price of a new watch, so it is not worth attempting.

Is there a way to make my Apple Watch battery last longer between charges?

Yes. Turn off features you do not use daily — disable background app refresh, reduce screen brightness, turn off always-on display, and disable location services for apps that do not need it. Keeping your watch software up to date also helps, as updates sometimes improve battery efficiency. These steps extend battery life but do not prevent the battery from aging over time.

Can I get a battery replacement if my watch is out of warranty but I did not buy AppleCare+?

Yes. You will pay the out-of-warranty service fee of $70 to $100 depending on your watch model. There is no way to avoid the fee if the watch is out of warranty and you do not have AppleCare+, but the replacement is still straightforward — contact Apple or an Authorized Service Provider and schedule the service.
