Yes, you can replace an iPhone battery, but Apple and authorized repair shops are your only reliable options

Apple designs iPhones so the battery is glued inside, not user-replaceable like older phones. You cannot open an iPhone yourself without damaging the screen, logic board, or waterproofing. However, Apple and Apple Authorized Service Providers will replace the battery for you — and as of 2021, Apple offers this service at a lower cost than it did before.

The real question is not whether replacement is possible, but where to get it done and what it will cost you. A battery replacement through Apple takes a few days to a week. Third-party repair shops can do it faster, but the quality and warranty vary widely. If your iPhone is still under warranty or AppleCare+, the cost may be zero.

Key Takeaways

  • Apple and Apple Authorized Service Providers are the only places that should replace your iPhone battery, because they have the right tools and parts to avoid damaging the screen or waterproofing.
  • Battery replacement costs between $69 and $99 depending on your iPhone model, but is free if your phone is under warranty or you have AppleCare+.
  • You can check your battery health in Settings > Battery > Battery Health & Charging to see if replacement is worth considering.
  • Apple's mail-in repair service lets you send your phone in if no local Apple Store is nearby, though it takes longer than in-store service.

What happens when you try to replace an iPhone battery yourself

Opening an iPhone requires removing the screen first, which is glued on with a strong adhesive. The battery sits underneath, also glued down. If you pry the screen without heating it, you will crack it. If you heat it unevenly, you risk melting the display cables or damaging the logic board underneath.

Even if you successfully remove the battery, the waterproofing seals are broken. Your phone will no longer be water-resistant. Reassembling it without the right adhesive and tools means the screen may separate later, or water may seep in during normal use.

Third-party repair shops that advertise fast battery replacement are doing this work, and they may do it well — but they are not using Apple parts or Apple's process. If something goes wrong, Apple will not repair the phone under warranty, and you have no recourse if the shop closes or refuses to stand behind their work.

How to get a battery replacement through Apple

Start by checking your battery health. Go to Settings, tap Battery, then Battery Health & Charging. You will see a percentage labeled "Maximum Capacity." If it is below 80 percent, your battery has degraded enough that replacement may be worth the cost. If it is above 80 percent, the battery is still functioning normally.

Once you decide to replace it, you have three options: visit an Apple Store in person, use Apple's mail-in repair service, or go to an Apple Authorized Service Provider. To find the nearest location, go to apple.com/support, enter your zip code, and select "Repair & Physical Damage." Apple will show you stores and authorized providers near you, along with wait times.

If you visit in person, bring your iPhone and a photo ID. The store will run a diagnostic to confirm the battery needs replacement, then do the work while you wait — usually within an hour. If you use mail-in service, you will pack your phone, ship it to Apple, and receive it back in five to seven business days. Mail-in service is free; you only pay for the repair itself.

What battery replacement costs

Apple charges $69 to replace the battery in an iPhone 15, iPhone 14, or iPhone 13. For older models like the iPhone 12 or iPhone 11, the cost is $69. For iPhone X, iPhone XS, or iPhone XR, it is $69. For iPhone 8 or earlier, it is $49.

If your iPhone is under the one-year limited warranty and the battery is defective, replacement is free. If you have AppleCare+, battery replacement is also free as long as the battery capacity has dropped below 80 percent due to normal use — not physical damage.

AppleCare+ costs $99 to $199 depending on the model and covers two years of accidental damage, hardware failures, and battery service. If you do not have it and your phone is out of warranty, you pay the full battery replacement cost.

Why authorized service providers are sometimes faster

Apple Authorized Service Providers are independent repair shops that Apple certifies and supplies with genuine parts. They follow Apple's repair procedures and can offer the same warranty as Apple on the work they do. Many of them have shorter wait times than Apple Stores, especially in areas where the nearest Apple Store is far away.

To find an authorized provider, search "Apple Authorized Service Provider" plus your city name, or use the Apple Support app. Call ahead to ask about wait times and whether they have your iPhone model in stock. Some providers can do the repair same-day; others may take a few days.

The cost is the same as Apple's, and the warranty is the same. The main difference is convenience — if an authorized provider is closer to you or has a shorter wait, it is a reasonable choice.

What to do if your iPhone is still under warranty

If your iPhone is less than one year old and the battery has degraded to below 80 percent capacity, Apple considers this a defect and will replace it for free. You do not need to pay anything. Bring your phone to an Apple Store or authorized provider with your receipt or proof of purchase.

If your phone is older than one year but you have AppleCare+, battery replacement is still free as long as the degradation is from normal use, not physical damage. AppleCare+ covers battery service for two years from the date you bought the phone.

If you are unsure whether your phone qualifies, ask the technician before they start the repair. They can check your purchase date and warranty status in their system.

When to replace your battery versus buying a new phone

A battery replacement costs $69 to $99 and takes a few days. A new iPhone costs $800 to $1,200. If your phone is otherwise working well — the screen is not cracked, the camera works, and it runs the apps you need — battery replacement is almost always the cheaper choice.

Battery degradation is normal and happens to every iPhone. At 80 percent capacity, your phone will still hold a charge for a full day of normal use, but you may notice it drains faster during heavy use or in cold weather. At 50 percent capacity, you will need to charge it more often. At very low capacity, the phone may shut down unexpectedly even when the battery shows charge remaining.

If you are considering a new phone because the battery is bad, replace the battery first. You may find the phone feels new again. If you want a new phone for other reasons — a better camera, faster processor, or newer features — that is a separate decision from battery health.

Frequently Asked Questions

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

Apple designs iPhone batteries to retain 80 percent of their capacity after 500 full charge cycles. In real use, this usually takes two to three years. A charge cycle means draining the battery from 100 percent to zero and charging it back to 100 — not the same as plugging it in once. Most people reach 500 cycles in two to three years of normal use.

Can I replace the battery myself if I buy the parts online?

You can buy replacement batteries and tools online, but doing the work yourself risks breaking the screen, damaging the logic board, or destroying the waterproofing. If something goes wrong, Apple will not repair the phone, and you have no warranty on the parts or the work. The $69 Apple charges for professional replacement is worth the safety and warranty.

What if I go to a non-Apple repair shop?

Non-Apple shops can replace your battery faster and sometimes cheaper, but they may use non-genuine parts, and Apple will not service the phone afterward if something goes wrong. If the shop closes or the battery fails early, you have no recourse. Authorized Service Providers are a safer middle ground — they use genuine parts and offer the same warranty as Apple.

Will replacing the battery erase my data?

No. Battery replacement does not touch your data. Your photos, messages, apps, and settings will be exactly as they were before. The technician only removes and replaces the battery itself.

How do I know if my battery needs replacement?

Go to Settings > Battery > Battery Health & Charging and look at the "Maximum Capacity" percentage. If it is below 80 percent and you notice the phone drains faster than it used to, replacement is worth considering. If it is above 80 percent, the battery is still healthy and replacement is not urgent.
