Apple won't replace the battery in your watch — you have to send it to Apple or go to a third-party repair shop

Apple does not sell watch batteries to consumers or let you open the watch yourself. If your battery no longer holds a charge, you have two paths: pay Apple to replace it, or take the watch to an independent repair shop. Apple's service costs between $70 and $100 depending on the model, takes about a week, and comes with a warranty. Third-party shops typically charge $40 to $80, work faster, but the repair is not covered by Apple if something goes wrong.

The battery in an Apple Watch is glued to the case, not screwed in. Opening it yourself will almost certainly damage the watch beyond repair. Even small mistakes — a slip with a tool, a drop of liquid on the circuit board, a bent ribbon cable — can cost you more than the repair itself.

Key Takeaways

  • Apple charges $70 to $100 to replace a watch battery and takes about a week, but the repair is covered if something goes wrong.
  • Third-party repair shops charge $40 to $80 and often complete the work in one to three days, but Apple will not warranty the repair.
  • The battery is glued into the case, so opening the watch yourself will almost certainly damage it permanently.
  • You can check your battery health in the Watch app on your iPhone to confirm the battery is the problem before paying for a repair.

How to check if the battery is actually the problem

Before you pay for a replacement, confirm that a failing battery is what you are dealing with. Open the Watch app on your iPhone, tap the Health tab at the bottom, then scroll down and tap Battery Health. The percentage shown is the maximum charge your battery can now hold compared to when it was new. If it is above 80 percent, the battery is probably not your problem — the watch may just need a restart or a software update.

If the percentage is below 80 percent and your watch drains in a few hours instead of a full day, a battery replacement will likely fix it. If the watch drains quickly but the battery health is still above 80 percent, the problem is probably a buggy app or a setting like always-on display that is using too much power. Try restarting the watch first: press and hold the side button until you see the power-off slider, then slide it to turn off the watch. Wait 10 seconds and press the side button again to turn it back on.

Sending your watch to Apple for a battery replacement

Go to apple.com/support, select Apple Watch, and choose the option for battery service. You can also call Apple Support at 1-800-MY-APPLE. They will ask for your watch model and serial number — you can find the serial number in the Watch app under General, then About. Apple will give you a shipping label and instructions for packing the watch safely.

Send the watch to Apple in its original box if you still have it, or in a small padded box with bubble wrap around it. Do not send the band unless Apple specifically asks you to. The repair usually takes five to seven business days after Apple receives it, plus shipping time both ways. You will get an email when the watch ships back to you.

Apple's battery replacement comes with a one-year limited warranty on the repair itself. If the new battery fails within that year, Apple will replace it again at no cost. Keep your receipt and the email confirmation from Apple in case you need to reference the warranty later.

Using a third-party repair shop

Search for "Apple Watch battery replacement near me" to find local shops. Check their reviews on Google Maps or Yelp, and call ahead to ask how long the repair takes and what they charge. Most independent shops can do the work in one to three days, and many offer same-day service if you drop it off in the morning.

Prices vary by location and shop, but expect to pay $40 to $80 for the battery and labor. Ask whether the shop uses genuine Apple batteries or third-party batteries — genuine batteries are more reliable but cost a bit more. Also ask what warranty they offer on the repair. Some shops may provide the battery for 30 days, others for a year.

The main trade-off is that Apple will not service your watch again if something goes wrong after a third-party repair. If the shop accidentally damages the screen or the case during the battery replacement, you are responsible for that damage. Choose a shop with good reviews and a clear warranty policy so you know what you are covered for.

What to do if your watch is still under AppleCare+

If you bought AppleCare+ when you got your watch, battery service is usually covered. Check your coverage by opening the Watch app on your iPhone, tapping the Health tab, and scrolling to the top — it will show your AppleCare+ status if you have it. You can also go to apple.com/support and sign in with your Apple ID to see your coverage.

If you have AppleCare+, contact Apple Support and mention your coverage. You will pay a service fee of $0 to $29 depending on your plan, instead of the full $70 to $100. The process is the same — Apple will mail you a shipping label and handle the repair.

When the watch is too old to repair

If your watch is more than five or six years old, Apple may tell you that parts are no longer available and they cannot repair it. This happens most often with the original Apple Watch (Series 0) and Series 1. In that case, your only option is to buy a new watch or try a third-party shop that specializes in older models.

Before you replace the watch, check the current price of a new model. If your watch is several years old and a new entry-level model costs less than $200, replacing it might be cheaper than paying for a repair plus shipping. If your watch is newer or you want to keep it, a third-party shop may still be able to help even if Apple cannot.

Frequently Asked Questions

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

Most Apple Watch batteries last three to four years with normal use. After that, the battery starts to hold less charge. You will notice the watch drains faster than it used to, even if you are not using it more. The battery health percentage in the Watch app will drop below 80 percent when it is time to think about a replacement.

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

You can buy a battery replacement kit online, but opening the watch yourself is not recommended. The battery is glued in, and the case is sealed with adhesive that is very hard to remove without damaging the screen, the case, or the internal components. Even if you succeed, you may break the water resistance seal, and the watch will no longer be waterproof. If something goes wrong, the repair cost will be much higher than paying Apple or a shop to do it.

Will Apple replace the battery for free if it is defective?

If your watch is still under the one-year limited warranty that comes with every Apple Watch, and the battery failure is a manufacturing defect rather than normal wear, Apple may replace it for free. Contact Apple Support with your purchase receipt. If the watch is older than one year, you will pay the standard service fee.

What happens to my data when I send the watch to Apple for repair?

Back up your watch data before you send it in. Open the Watch app on your iPhone, go to General, then About, and scroll down to see your storage. Your data is stored on your iPhone as well, so you will not lose it, but backing up first is a safe step. When you get the watch back, your data will sync automatically when you pair it again.

Is it cheaper to buy a new watch than to replace the battery?

If your watch is three or four years old, a battery replacement for $70 to $100 is usually much cheaper than a new watch, which costs $250 and up. If your watch is six or seven years old and a new model is on sale, do the math: add the repair cost to the cost of keeping the old watch running, and compare that to the price of a new one. Older watches may also start having other problems soon, so a replacement might make sense.
