Yes, iPhone batteries can be replaced, but where and how depends on your model and warranty

Your iPhone battery can be replaced through Apple, an Apple Authorized Service Provider, or an independent repair shop. Apple will replace the battery in any iPhone model, though the cost and time vary. If your phone is under warranty or covered by AppleCare+, the replacement may be free or discounted. Independent shops often charge less but may void your warranty, and the quality of parts and work varies widely.

The process itself is straightforward for Apple and authorized providers—they remove the old battery, install a new one, and run diagnostics. You do not need to back up your data or erase your phone; the battery replacement does not touch your files. Turnaround time ranges from same-day at some Apple Stores to several days by mail.

Key Takeaways

  • Apple replaces iPhone batteries at its stores and through mail-in service, with costs ranging from free (under warranty or AppleCare+) to around $69 for out-of-warranty replacements.
  • An Apple Authorized Service Provider can also replace your battery and may have shorter wait times than an Apple Store in some areas.
  • Independent repair shops charge less but use parts that may not be genuine Apple batteries, and the work typically voids any remaining warranty.
  • Battery replacement does not erase your data or require you to set up your phone again—only the battery is swapped out.
  • You can check your battery health in Settings > Battery > Battery Health & Charging to see if replacement is worth considering.

How to get your battery replaced at Apple

Start by visiting apple.com/support or opening the Support app on your iPhone. Select your device, then choose "Battery and Charging" as the issue. You will see options to book an appointment at an Apple Store or arrange mail-in service. If you choose the store, you can often get a same-day replacement if you arrive early, though busy locations may ask you to return later.

For mail-in service, Apple will send you a prepaid shipping box. You pack your iPhone, drop it off at a carrier location, and Apple receives it within a few days. The battery replacement itself takes one to two business days once Apple has your phone. You will receive it back with a new battery and a tracking number so you can monitor its return.

Bring your phone and a valid ID to an in-store appointment. If your iPhone is under warranty or you have AppleCare+, bring proof—your receipt, order confirmation email, or the original box. Apple will check your coverage before quoting a price.

Cost of battery replacement at Apple

If your iPhone is within one year of purchase and the battery is defective, Apple replaces it free under the standard limited warranty. If you have AppleCare+, battery replacement is free for the duration of your coverage, even if the battery is straightforward worn out from normal use.

Out-of-warranty battery replacement costs approximately $69 for most iPhone models, though the exact price varies slightly by model. Older iPhones like the iPhone 6s or iPhone 7 may cost slightly less; newer models like the iPhone 15 may cost slightly more. Apple will quote the exact price when you book your appointment.

If your phone has other damage—a cracked screen or water damage—Apple may require you to repair those issues first or may charge a higher fee. Ask about the total cost before you authorize the work.

Using an Apple Authorized Service Provider

Apple Authorized Service Providers are independent businesses certified by Apple to perform repairs using genuine Apple parts. You can find one near you by visiting apple.com/support and searching for service locations. Many Best Buy locations, carrier stores, and local repair shops hold this certification.

Authorized providers follow the same warranty and pricing rules as Apple Stores. Out-of-warranty battery replacement costs the same, and AppleCare+ coverage works the same way. The main advantage is convenience—an authorized provider near your home or work may have shorter wait times than your nearest Apple Store.

Ask the provider whether they have the battery in stock before you visit. Some authorized providers order parts from Apple and may take longer than an Apple Store for less common models.

Independent repair shops and what to know

Independent repair shops—local businesses not certified by Apple—typically charge $30 to $50 for an iPhone battery replacement, significantly less than Apple. However, they usually use third-party batteries rather than genuine Apple parts. Third-party batteries work, but they may not hold a charge as long, may not report accurate health information to your phone, and occasionally fail sooner than Apple batteries.

Choosing an independent shop voids any remaining manufacturer warranty on your iPhone. If something else breaks after the repair, Apple will not cover it under warranty, though the shop's own warranty on the battery repair usually lasts 30 to 90 days. Check the shop's reviews on Google or Yelp before you go, and ask whether they offer a warranty on the battery itself.

Some independent shops also use refurbished or used batteries instead of new ones. Ask explicitly whether the battery is new before you authorize the work. A new third-party battery is usually reliable; a used one carries more risk.

What happens during the battery replacement

The technician will power off your iPhone, remove the screen or back panel (depending on the model), disconnect the old battery, and install the new one. For newer iPhones, this takes 30 minutes to an hour. Older models with removable batteries take less time. The technician will then power on the phone, run diagnostics to confirm the new battery is recognized, and check that charging works.

Your data, apps, photos, and settings remain untouched. You do not need to back up your phone beforehand, and you will not see a setup screen when you turn it back on. The phone will work exactly as it did before, except with a fresh battery.

If the technician discovers other damage during the replacement—a swollen battery that damaged the phone's frame, or corrosion inside—they will let you know before proceeding. You can then decide whether to authorize additional repairs or just replace the battery.

When to replace your battery

Check your battery health by opening Settings, tapping Battery, then Battery Health & Charging. The "Maximum Capacity" percentage shows how much charge your battery holds compared to when it was new. If it is below 80 percent and your phone is more than two years old, replacement is worth considering. If it is below 50 percent, the phone will drain quickly and replacement will noticeably improve daily use.

You may also notice your phone shutting down unexpectedly at 20 or 30 percent battery, or taking much longer to charge. These are signs the battery is failing and replacement will help. If your phone is still under warranty or you have AppleCare+, there is no downside to replacing it sooner rather than later.

If your maximum capacity is above 85 percent and your phone is less than three years old, replacement is probably not necessary yet. Batteries degrade naturally over time, and waiting until capacity drops further will save you money.

Frequently Asked Questions

Does replacing the battery erase my phone or require me to set it up again?

No. Battery replacement does not touch your data, apps, or settings. Your phone will turn on exactly as it was before, with all your information intact. You will not see a setup screen or need to sign in again.

How long does a new iPhone battery last?

A new battery is designed to retain 80 percent of its capacity after 500 full charge cycles, which typically takes two to three years of normal daily use. After that, capacity gradually declines. Most people notice a significant difference in battery life after three to four years.

Can I replace the battery myself?

You can, but it is difficult and risky. iPhones are glued together, and opening one without the right tools can damage the screen or internal components. If you damage something during the attempt, Apple will not repair it under warranty. Unless you have experience with phone repair, professional replacement is safer and often cheaper than replacing a broken screen.

Will replacing the battery fix my phone if it is running slowly?

Not always. Slow performance is usually caused by software, storage space, or a damaged processor—not the battery. A worn battery can cause unexpected shutdowns that feel like slowness, but if your phone is slow even when the battery is fully charged, replacement will not help. Check your storage in Settings > General > iPhone Storage; if you are using more than 90 percent, freeing space may improve speed.

What is the difference between AppleCare+ and the standard warranty for battery replacement?

The standard one-year warranty covers battery replacement only if the battery is defective—meaning it fails to hold a charge through no fault of yours. AppleCare+ covers battery replacement even if the battery is straightforward worn out from normal use, and it extends coverage for two or three years depending on your plan. AppleCare+ costs extra upfront but saves money if you need multiple repairs.
