Yes, Apple Watch batteries can be replaced, but the process and cost depend on your model and warranty status
Apple Watch batteries do wear out over time. Most batteries retain about 80 percent of their capacity after 1,000 charge cycles, which typically takes two to three years of normal use. When your battery no longer holds a charge through the day, you have two main routes: Apple's official service or a third-party repair shop.
Apple replaces batteries through its service centers and authorized repair providers. The cost ranges from $70 to $100 depending on your watch model, plus $6.95 shipping if you mail it in. The process takes five to seven business days after Apple receives your device. If your watch is still under the one-year limited warranty and the battery failure is a manufacturing defect, Apple replaces it at no cost.
Third-party repair shops often charge $30 to $60 and can complete the work in one to two hours while you wait. However, opening your watch yourself or using an unauthorized repair shop voids any remaining warranty coverage and may damage the water resistance seal.
Key Takeaways
- Apple charges $70 to $100 for battery replacement plus shipping, with a turnaround of five to seven business days.
- If your watch is under one year old and the battery failure is a manufacturing defect, Apple replaces it free under warranty.
- Third-party repair shops charge less ($30 to $60) and work faster (one to two hours), but opening your watch voids the warranty and may break the water-resistant seal.
- Battery degradation is normal after two to three years of daily use, and you cannot replace the battery yourself without specialized tools.
How to tell if your Apple Watch battery needs replacement
Your battery is failing if your watch shuts down before the end of the day despite a full charge, or if it drains 10 to 15 percent per hour during normal use. You can check battery health in the Watch app on your iPhone: open Settings, tap Battery, then Battery Health. If the maximum capacity is below 80 percent, replacement will noticeably improve performance.
Some watches show a red battery icon or enter low-power mode frequently. This is a sign the battery can no longer deliver the power the watch needs. Older models (Series 3 and earlier) are more likely to need replacement after three to four years.
Apple's official battery replacement process
You can start a repair through Apple's website, in an Apple Store, or by calling Apple Support at 1-800-MY-APPLE. Apple will ask your watch model, serial number, and description of the problem. If you choose mail-in service, Apple sends you a prepaid shipping label. You pack the watch and drop it off at any UPS location.
Apple receives your watch, diagnoses it, and performs the replacement. The entire process takes five to seven business days after arrival. You receive the watch back with a new battery and a 90-day warranty on the repair. If you take it to an Apple Store in person, the wait is usually one to two hours for a same-day replacement, though availability varies by location.
The cost is $70 for Series 3 and earlier, $79 for Series 4 through Series 8, and $99 for Ultra models. AppleCare+ covers battery replacement at no cost if the battery capacity drops below 80 percent, but you must have purchased AppleCare+ within 60 days of buying the watch.
Third-party repair shops and their trade-offs
Independent repair shops and electronics retailers like Best Buy's Geek Squad offer faster service at lower cost. Typical pricing is $30 to $60, and most shops complete the work while you wait. Some shops can replace the battery in 30 minutes to two hours depending on how busy they are.
The main risk is that opening your watch can damage the adhesive seal that makes it water-resistant. If the technician does not properly reseal the watch, water can enter and damage the internal components. Additionally, using a non-Apple battery may result in reduced battery life or compatibility issues with future watchOS updates.
Once you use a third-party repair shop, any remaining Apple warranty is void. If something else fails on the watch within the next year, Apple will not cover it under warranty. Check whether the repair shop offers its own warranty on the battery and labor before you commit.
What to do if your watch is still under warranty
If you purchased your Apple Watch less than one year ago and the battery is failing, contact Apple before paying for any repair. Apple's one-year limited warranty covers manufacturing defects, which includes premature battery failure. You will not pay anything if Apple determines the battery failed due to a defect rather than normal wear.
Apple will ask you to describe the problem and may ask when you purchased the watch. Have your receipt or order confirmation ready. If you bought it from an Apple Store, they can look up the purchase date using your phone number or email. If the watch is still under warranty, Apple will replace the battery at no cost and return it within five to seven business days.
AppleCare+ and battery coverage
AppleCare+ is a two-year protection plan that costs $79 for most models and $99 for the Ultra. It covers battery replacement at no cost if capacity drops below 80 percent. Without AppleCare+, you pay the standard service fee ($70 to $99) for battery replacement.
AppleCare+ also covers accidental damage with a $99 deductible per incident, which can be valuable if you drop your watch or get it wet. However, you must purchase AppleCare+ within 60 days of buying the watch. If your watch is already two years old, AppleCare+ is no longer available.

Frequently Asked Questions
Can I replace the Apple Watch battery myself?
You can, but it is not recommended. The watch is sealed with adhesive, and opening it requires a heat gun, specialized prying tools, and steady hands. If you crack the screen or damage the seal, repair costs jump to $200 or more. Most people are better off paying a professional.
How long does an Apple Watch battery last before it needs replacement?
Most Apple Watch batteries last two to three years with daily use. After that, capacity drops below 80 percent and you will notice the watch drains faster. Older models (Series 3 and earlier) may need replacement sooner, sometimes after 18 to 24 months.
Will Apple replace my battery if I bought the watch used?
Yes, but only if it is still within the one-year warranty period from the original purchase date. If the watch is older than one year, you pay the standard service fee. Apple does not require proof of purchase for warranty service if they can verify the device in their system.
What happens if I use a non-Apple battery?
Third-party batteries may work, but they often have shorter lifespan and may not be optimized for your watch model. Some users report reduced battery life or issues with watchOS updates. The bigger risk is that opening the watch to install a third-party battery can break the water-resistant seal.
Is it worth buying a new watch instead of replacing the battery?
If your watch is more than three years old, replacement might make sense. A new entry-level Apple Watch (Series 9 or SE) costs $249 to $399, while battery replacement costs $70 to $99. However, if your watch still works otherwise and you like the model, battery replacement is the cheaper option.
