Yes, you can replace your iPhone battery, but where and how depends on your model and warranty

Apple will replace your iPhone battery for a flat fee at any Apple Store or Apple Authorized Service Provider. If your phone is still under warranty or covered by AppleCare+, the replacement may be free. You can also mail your phone to Apple for battery service. Third-party repair shops offer battery replacement too, though this voids your warranty and may affect water resistance on newer models.

The cost and process differ based on whether your iPhone has a removable battery (it doesn't — all modern iPhones have sealed batteries) and your phone's age. Older iPhones outside warranty cost less to repair than newer models. The entire process typically takes three to five business days if you mail it in, or same-day if you book an appointment at an Apple Store.

Key Takeaways

  • Apple charges a flat fee for out-of-warranty battery replacement, ranging from $69 to $99 depending on your iPhone model.
  • If your phone is under warranty or you have AppleCare+, battery replacement is free if the battery health has degraded below 80 percent.
  • You can start a repair at apple.com, by calling Apple Support, or by walking into an Apple Store with an appointment.
  • Third-party repair shops cost less but may damage water sealing and will void your Apple warranty.
  • Battery replacement takes one to five business days depending on whether you choose in-store, mail-in, or third-party service.

How to check if your battery needs replacement

Your iPhone tells you when the battery is degrading. Go to Settings, then Battery, then Battery Health & Charging. Look at the number next to "Maximum Capacity." If it shows 80 percent or lower, your battery is wearing out and Apple will replace it for free if you have AppleCare+ or are still under the original one-year limited warranty.

You will also see a section called "Charging Optimization" that shows whether your phone is slowing down to protect the battery. If you see a message saying your battery needs service, that is Apple's way of saying the battery is failing and should be replaced soon. Do not ignore this — a failing battery can shut your phone off suddenly even when it shows charge remaining.

Getting a battery replacement at an Apple Store

Visit apple.com/repair, select your device, and choose "Battery" as the issue. Enter your phone number and zip code. Apple will show you nearby stores with available appointment slots. Book the time that works for you. Bring your iPhone and a valid ID.

When you arrive, a technician will confirm your battery health, tell you the cost, and perform the replacement while you wait — usually within two hours. You will get your phone back the same day with a new battery and a 90-day warranty on the repair. If the store is busy, they may ask you to leave your phone and pick it up later that day or the next morning.

Mailing your iPhone to Apple for battery service

If no Apple Store is near you, start a repair at apple.com/repair and select "Mail-in Repair." Apple will email you a prepaid shipping label. Pack your iPhone in a box with padding and drop it at any UPS location. Apple receives it, diagnoses the battery, performs the replacement, and ships it back — all within five to seven business days.

You do not need to include the charger or cables, only the phone itself. Apple will text and email you updates as your phone moves through the repair process. Once it ships back to you, you will have 90 days to report any problems with the repair. If something goes wrong during shipping, Apple's insurance covers it.

What Apple charges for battery replacement

Out-of-warranty battery replacement costs $69 for iPhone SE and iPhone 11, and $79 to $99 for iPhone 12 and newer models. The exact price depends on your specific model — newer and larger phones cost more. These prices are the same whether you go in-store or mail-in.

If you have AppleCare+, battery replacement is free as long as the battery health is below 80 percent. If your phone is within one year of purchase and shows a battery defect, the replacement is also free under Apple's limited warranty. Ask the technician to check your warranty status before you pay.

Using a third-party repair shop

Independent repair shops and chains like iFixit, uBreakiFix, and Best Buy Geek Squad offer iPhone battery replacement for $40 to $70, undercutting Apple's prices. The work is usually done the same day. However, third-party repairs void your Apple warranty immediately, and the shop may not be able to restore full water resistance on iPhone 11 and newer models because the seal requires special equipment.

If you choose a third-party shop, ask whether they use genuine Apple batteries or third-party batteries. Genuine batteries last longer and charge more reliably. Also ask about their warranty on the repair itself — reputable shops offer 30 to 90 days of coverage if the battery fails prematurely. Check reviews on Google or Yelp before you go, because quality varies widely between locations.

What happens during a battery replacement

The technician removes the screen, disconnects the old battery, and installs a new one. The entire process takes 30 minutes to two hours depending on the shop and how busy they are. Your data stays on the phone — the technician does not erase anything. You will not lose photos, messages, apps, or settings.

After the replacement, your phone will show 100 percent battery capacity in Settings > Battery > Battery Health & Charging. The new battery will charge and drain normally. If you notice the phone still shuts off unexpectedly or charges slowly after replacement, contact the shop or Apple within the warranty period — the battery may be defective.

When you should not replace the battery yourself

iPhone batteries are glued in place and require special tools to remove safely. Attempting a DIY replacement risks damaging the screen, logic board, or battery itself. A punctured battery can catch fire. Unless you have professional electronics repair experience, the cost of fixing accidental damage will exceed what you save on labor.

If you are determined to try, iFixit sells battery replacement kits with tools and instructions for around $30 to $50. The kit includes the battery, adhesive strips, and a pentalobe screwdriver. Even with a kit, the process takes one to three hours and requires patience. Most people find it easier and safer to pay a technician.

Frequently Asked Questions

How long does an iPhone battery last before it needs replacement?

Apple designs iPhone batteries to retain 80 percent capacity after 500 full charge cycles. In real use, that usually means two to three years before the battery noticeably degrades. Some people see degradation sooner if they charge in extreme heat or cold, or if they drain the battery to zero frequently.

Will replacing the battery fix my phone if it keeps shutting off?

If your battery health is below 80 percent and your phone shuts off unexpectedly, a replacement will almost certainly fix it. If your battery health is still above 80 percent but the phone still shuts off, the problem is something else — possibly the power management chip or logic board — and a technician should diagnose it before you pay for a battery replacement.

Can I replace the battery on an older iPhone model?

Yes. Apple replaces batteries on iPhone 6 and newer. Older models are no longer serviced by Apple, but some third-party shops still work on them. Call ahead to confirm they have the right battery in stock, because older batteries are harder to find.

What is the difference between a genuine Apple battery and a third-party battery?

Genuine Apple batteries are made to Apple's specifications and last longer. Third-party batteries are cheaper but may not hold a charge as well or last as long. Some third-party batteries also report incorrect capacity to your phone, so Settings shows 100 percent when the battery is actually degraded.

Do I need to back up my phone before battery replacement?

No. Battery replacement does not erase your data. However, it is always good practice to back up your phone regularly in case something unexpected happens during any repair. Use iCloud or a computer to back up before you go in.
