Apple Watch battery replacement: How much does it cost and is it worth it?

Should you replace your Apple Watch's battery or upgrade to a new model?

When you spend a lot of money on one of the best Apple Watch models , you want it to last as long as possible. But inevitably, as with any device that uses lithium-ion batteries, the battery will slowly degrade over time. You'll find it draining faster and faster, and you'll have to recharge it more often. Thankfully, this doesn't necessarily mean you'll have to toss the watch into a recycling bin and buy a new one. Apple Watch batteries can be replaced, which is a consideration worth making to extend the life of the device while also helping the environment.

Spending the $99 it typically costs to fix the watch through Apple can be worth it to get more usage from a wearable that cost you hundreds of dollars — assuming it still has life left it in otherwise. You'll have to determine if that money is better spent on an upgrade for the refined design and exclusive features of a more recent model, keeping watchOS compatibility in mind.

You can arrange Apple Watch repairs directly through Apple , and the price is generally a flat fee of $99. Other retailers like Best Buy serve as Apple authorized Apple Watch service and repair providers, offering the same repair or replacement service for an equal fee. Typically, the process will take about a week, and you can schedule it online or in store.

If you have an active AppleCare plan on your device, that covers battery issues, including if the battery capacity drops below 80%. However, it does not cover normal degradation of the battery over time. Chances are, if this is the case, your Apple Watch is long outside of its warranty and extended warranty period anyway. There is an option to get ongoing AppleCare for Apple Watch for a monthly or yearly fee until you cancel. But this still includes service fees and/or deductibles and doesn't cover battery depletion from normal use.

Another option, if you're confident enough to consider it, is a DIY replacement. You'll find batteries offered by companies like iFixit, though the company only sells batteries for the original and Series 1 models. After acquiring a replacement battery for a newer model elsewhere, you can use iFixit's detailed instructional guides on how to swap it out manually. But this is not recommended unless you feel comfortable handling the intricate repair process; there are risks that come with attempting it yourself.

While eliminating e-waste and extending the life of tech products is great, there comes a time when an Apple Watch isn't worth bringing back to life with a new battery. First, consider software support. The latest watchOS 27 drops support for many older devices ; it's only available for the Apple Watch Series 9, SE 3, and Ultra 2 and newer. That means if you own an Apple Watch Series 8 or older model, you won't get the latest software update. Your watch will continue to work just fine, though.

In fact, many people report still using models as old as the Series 4 today. The previous generation watchOS 26 had wider compatibility, working with models dating back to the Apple Watch Series 6 and second-generation SE. This means the Apple Watch Series 5 and first-generation SE (and older) are no longer supported, with their software end of life dating back to September 2024.
