Apple Watch batteries can be replaced, but not by you
You cannot replace an Apple Watch battery yourself. The watch is sealed with adhesive, and opening it risks breaking the screen, the case, or the water resistance seal. Apple's official route is to visit an Apple Store or an Apple Authorized Service Provider, where a technician will remove the old battery and install a new one. The process takes about an hour, and you will pay a flat fee that varies by watch model — typically between $70 and $100 for most models, though newer or larger watches may cost more.
If your watch is still under warranty or covered by AppleCare+, the battery replacement may be free or cost only the AppleCare+ service fee. Outside warranty, you pay the full replacement cost. A third-party repair shop may charge less, but Apple does not may provide their work, and some shops may damage your watch in the process.

How to book a battery replacement at Apple
Start by visiting apple.com/support or opening the Apple Support app on your iPhone. Select your Apple Watch model and describe the issue — choose "Battery" or "Power" from the menu. The site will show you nearby Apple Stores and authorized service providers, along with their hours and whether they have same-day appointments available.
Click "Book a Repair" next to the location you prefer. You will need to sign in with your Apple ID and provide your watch's serial number, which you can find in the Apple Watch app under General > About. Select your preferred date and time, and Apple will send you a confirmation email with instructions on what to bring — usually just your watch and your ID.
If no Apple Store is near you, search for "Apple Authorized Service Provider" plus your city name to find independent shops that Apple has certified. Call ahead to confirm they do battery replacements and ask about their current wait time, since some locations book weeks out.
What happens during the replacement
When you arrive, the technician will inspect your watch to confirm the battery is the problem. If your watch has other damage — a cracked screen, for example — they will tell you the cost before proceeding. For a battery-only replacement, they will remove the back case, disconnect the old battery, and install a new one. They will then test the watch to confirm it powers on and holds a charge.
The technician will also re-seal the case and re-explore the adhesive that makes your watch water-resistant. This is why you cannot do this at home — the seal is critical. Once the adhesive sets, your watch will be water-resistant again to its original rating (usually 50 meters for most models).
The whole process usually takes 30 minutes to an hour. Some locations may ask you to leave your watch and pick it up later if they are busy, so ask when you book whether you can wait.
Cost breakdown by Apple Watch model
| Watch Model | Typical Battery Replacement Cost |
|---|---|
| Apple Watch Series 3 or earlier | $70 |
| Apple Watch Series 4–8, SE | $79 |
| Apple Watch Ultra | $99 |
| With AppleCare+ (in warranty) | $0 or $69 service fee |
Prices may vary by region and are subject to change. If your watch is out of warranty but you have AppleCare+, you will pay a $69 service fee instead of the full replacement cost. AppleCare+ covers two accidental damage incidents per year, plus battery service.
If your watch is damaged in addition to the battery — for example, a cracked screen — the technician will quote you for both repairs. You can choose to replace only the battery and leave the screen damage, or pay for both at once. Some people prefer to replace the battery first and then decide whether to repair cosmetic damage.
When to replace your battery
Apple Watch batteries degrade over time. A new battery holds a full charge for about 18 hours of typical use. After two to three years, the battery may hold only 80 percent of its original charge. After three to four years, you may notice the watch dies by mid-afternoon even with light use.
You do not have to replace the battery the moment it degrades — if you are comfortable charging your watch more often, you can wait. But if the watch no longer lasts a full day, replacement is the only way to restore it. Closing apps, reducing brightness, or disabling features like the always-on display may extend battery life temporarily, but they do not fix a worn battery.
If your watch is more than five years old, consider whether replacement is worth the cost. A new Apple Watch often costs $250 to $400, so if your current watch is very old and has other wear, you may prefer to upgrade rather than repair.
Third-party repair shops and mail-in services
Some independent repair shops and mail-in services advertise Apple Watch battery replacements for $40 to $60, significantly less than Apple's price. These shops are not authorized by Apple and do not have access to genuine Apple parts or the same tools that Apple technicians use.
The main risk is that opening the watch incorrectly can crack the screen, damage the logic board, or break the water resistance seal. If something goes wrong, you have no recourse — Apple will not repair a watch that has been opened by an unauthorized shop, and the third-party shop may not cover the damage. Some shops do offer a warranty on their work, so ask before you commit.
Mail-in services ask you to ship your watch to them, they replace the battery, and they ship it back. This adds shipping time (usually one to two weeks total) and the risk that your watch could be lost or damaged in transit. Use a mail-in service only if no Apple Store or authorized provider is within reasonable distance.
What to do if your watch is still under warranty
If your Apple Watch is less than one year old and the battery is failing, the replacement is free under Apple's standard warranty. Bring your watch and proof of purchase (your receipt or your Apple ID order history) to an Apple Store or authorized provider. They will verify the warranty status and replace the battery at no cost.
If you purchased AppleCare+ when you bought the watch, you have two years of coverage from the purchase date. Battery service is included, so you pay only the $69 service fee (or nothing if the battery failure is not due to accidental damage). Check your AppleCare+ status in the Apple Watch app under General > About > AppleCare+ Status.
If you are not sure whether your watch is still under warranty, visit apple.com/support, enter your serial number, and Apple will tell you the coverage status and expiration date.
Frequently Asked Questions
How long does an Apple Watch battery last before it needs replacement?
Most Apple Watch batteries degrade noticeably after two to three years of daily use. By year four or five, the watch may not last a full day on a single charge. The exact timeline depends on how often you charge it and which features you use — always-on display and constant heart rate monitoring drain the battery faster.
Can I replace the battery myself with a kit from online?
You can buy battery replacement kits online, but opening the watch yourself risks breaking the screen, damaging the water resistance seal, or destroying the logic board. Unless you have experience with watch repair, the cost of a failed DIY attempt will exceed the cost of professional replacement. Apple does not support self-repairs.
What if my Apple Watch battery swells or overheats?
A swollen or overheating battery is a safety issue. Stop using the watch when ready and do not attempt to open it. Take it to an Apple Store or authorized provider as soon as possible. If the battery is visibly swollen, tell the technician when you arrive so they can handle it safely.
Will I lose my data if I replace the battery?
No. The battery replacement does not erase your watch data. Your activity history, apps, and settings will remain on the watch after the technician installs the new battery. The watch will sync with your iPhone as usual once you turn it back on.
How do I find an Apple Authorized Service Provider near me?
Visit apple.com/support, select your Apple Watch, and choose "Repair and Physical Damage." The site will show you nearby Apple Stores and authorized providers with their addresses and hours. You can also call Apple Support at 1-800-MY-APPLE to find a provider in your area.
