When and How to Replace Your Apple Watch Battery
Apple Watch batteries cannot be replaced by the owner — you must send the watch to Apple or visit an Apple Store to have the battery swapped out. Apple does not sell replacement batteries for individual purchase, and opening the watch yourself will damage the water resistance seal and void any warranty. The process takes about one to two weeks if you mail it in, or same-day if you visit a physical store with an appointment.
Most Apple Watch models need a battery replacement every two to three years of regular use, though this varies based on how often you charge it and which model you own. The original Series 1 and Series 2 watches are no longer serviced by Apple, so if you own one of these, replacement is not an option through official channels.
Key Takeaways
- Apple Watch batteries must be replaced by Apple or an authorized service provider — you cannot do it yourself without breaking the water seal.
- Battery replacement costs between $79 and $99 depending on your watch model, plus tax, and takes one to two weeks by mail or same-day at an Apple Store with an appointment.
- You can check your battery health in the Settings app under Battery, and a watch that holds less than 80 percent of its original charge is a candidate for replacement.
- If your watch is out of warranty, you still pay the same service fee; AppleCare+ does not cover battery replacement unless the battery fails unexpectedly.
- Authorized third-party repair shops may offer battery replacement at lower cost, but they cannot may provide water resistance after the repair.
How to Check Your Apple Watch Battery Health
Before you decide to replace the battery, check how much capacity it has lost. Open the Settings app on your Apple Watch, scroll down to Battery, and tap Battery Health. The screen will show the maximum capacity as a percentage of the original. A battery at 80 percent or higher still holds most of its charge, but one below 60 percent will drain noticeably faster than when the watch was new.
You can also check battery health from your iPhone: open the Watch app, go to General, then About, and look for Battery Health. This shows the same information and is often easier to read on a larger screen. If the percentage is dropping quickly month to month, the battery is degrading faster than normal and replacement is worth considering sooner rather than later.
Replacing Your Battery at an Apple Store
The fastest way to replace your battery is to visit an Apple Store in person. Go to apple.com, click Find a Store, and locate the nearest location. Call ahead or use the Apple Store app to book a Genius Bar appointment — walk-ins may wait several hours or be turned away if the store is busy. Tell the appointment scheduler that you need battery service.
Bring your Apple Watch and your ID. The technician will confirm the battery capacity in front of you, discuss the cost (typically $79 to $99 depending on your model), and replace the battery while you wait. Most in-store replacements take 30 minutes to an hour. You will pay at the time of service, and the watch comes back with a new battery and a 90-day warranty on the repair.
Mailing Your Watch to Apple for Battery Service
If no Apple Store is nearby, you can mail your watch to Apple for battery replacement. Start at support.apple.com, search for "battery service," and select your watch model. Click the option to set up mail-in service. Apple will email you a prepaid shipping label and instructions for packing the watch securely.
Place your watch in a small box with padding, print the label, and drop it at any UPS location. Apple typically receives it within three to five business days, completes the replacement within two to three business days, and ships it back. Total time is usually one to two weeks. You will receive an email when the watch arrives at Apple and another when it ships back to you. The cost is the same as in-store service, and you pay when you set up the order online.
What Happens If Your Watch Is Still Under Warranty
If your Apple Watch is less than one year old and the battery is failing due to a manufacturing defect — meaning it drains much faster than normal for its age — Apple may replace it at no cost. However, normal battery degradation after one year is not covered by the standard one-year warranty. You will still pay the service fee.
If you purchased AppleCare+ for your watch, the coverage extends to two years from the purchase date and includes accidental damage protection, but it does not waive the battery service fee. AppleCare+ only covers battery replacement if the battery fails unexpectedly and is not caused by normal wear. In most cases, you will pay the standard $79 to $99 fee regardless of whether you have AppleCare+.
Third-Party Repair Shops and Battery Replacement
Some independent repair shops and authorized service providers offer Apple Watch battery replacement at lower prices — sometimes $40 to $60 instead of $79 to $99. These shops are listed on Apple's official Authorized Service Provider directory. Before you choose one, confirm that they are on that list, because unauthorized shops may use lower-quality batteries or damage the watch during repair.
Keep in mind that third-party repairs do not may provide the same water resistance as Apple's service. If water resistance is important to you — for swimming or showering — stick with Apple or a shop that explicitly guarantees water resistance after the repair. Ask the shop in writing what warranty they offer on the battery and the water seal before you leave your watch with them.
Common Mistakes to Avoid
Do not attempt to open your Apple Watch yourself. The case is sealed with adhesive, and prying it open will crack the screen, damage the battery connector, and destroy the water resistance seal. Even if you succeed in replacing the battery, the watch will no longer be waterproof and may not function correctly.
Do not wait until your battery is completely dead to seek service. A battery that no longer holds a charge at all may be harder to test and diagnose, and the watch may not power on during the repair process. If your watch will not turn on, mention this when you book your appointment so the technician is prepared.
Do not assume that a slow watch is always a battery problem. If your watch is running slowly or freezing, the issue may be software-related, not the battery. Restart the watch by holding the side button until the power-off slider appears, then drag it to turn off the watch. Wait 10 seconds and hold the side button again to turn it back on. If performance improves, the battery may not be the issue.
Frequently Asked Questions
How much does an Apple Watch battery replacement cost?
Battery replacement costs between $79 and $99 depending on your watch model, plus applicable sales tax. The price is the same whether you go to an Apple Store or use mail-in service. AppleCare+ does not reduce this fee for normal battery degradation.
Can I replace the battery myself?
No. Opening an Apple Watch yourself will break the water resistance seal and likely damage internal components. Apple does not sell replacement batteries for individual use, and any damage from self-repair voids your warranty.
How long does battery replacement take?
At an Apple Store with an appointment, replacement usually takes 30 minutes to an hour. Mail-in service takes one to two weeks total, including shipping time both ways. Some authorized third-party shops may be faster, but confirm their turnaround time before you drop off your watch.
Will my watch still be waterproof after battery replacement?
Yes, if the replacement is done by Apple or an authorized service provider. Apple's technicians reseal the watch to the original water resistance rating. Third-party shops may not may provide water resistance, so ask in writing before you use them.
What if my Apple Watch battery drains in a few hours?
Rapid battery drain can be caused by a failing battery, but it can also be caused by background app activity, high screen brightness, or a software bug. Before you pay for battery service, try restarting the watch, turning off background app refresh in Settings, and lowering the brightness. If the problem persists after a restart, battery replacement may be necessary.
