Yes, you can replace an iPhone battery, but the method depends on your phone model and whether you do it yourself or use Apple

You can replace an iPhone battery in three ways: through Apple's official service, through an authorized Apple repair partner, or by doing it yourself if you have the right tools and your phone model supports it. Apple charges between $69 and $99 for a battery replacement depending on your iPhone model. Self-replacement is possible on some newer iPhones, but it requires opening the phone and disconnecting components—a process that voids your warranty if something goes wrong.

The easiest and safest route for most people is Apple's service. You can start a repair through Apple's website, visit an Apple Store, or contact an authorized repair shop. The process typically takes three to five business days if you mail it in, or same-day if you have an appointment at a physical location.

Key Takeaways

  • Apple charges $69 to $99 for a battery replacement depending on your iPhone model, and the repair usually takes three to five business days by mail or same-day at an Apple Store.
  • You can replace the battery yourself on iPhone 15 and newer models using Apple's Self Service Repair program, which requires purchasing or renting a battery replacement kit.
  • Self-replacement voids your warranty and requires opening your phone, disconnecting the display, and removing adhesive strips—mistakes can damage the phone permanently.
  • Authorized third-party repair shops often charge less than Apple but may not use genuine Apple batteries, which can affect performance and longevity.
  • If your iPhone is still under warranty and the battery has degraded due to a manufacturing defect, Apple will replace it at no cost.

Using Apple's official battery replacement service

Apple's battery replacement is the most straightforward option. Visit apple.com/support, select your iPhone model, and choose "Battery Service." You can schedule an appointment at an Apple Store, mail your phone to Apple, or find an authorized repair location near you. Apple will test your battery first to confirm it needs replacement—if your battery health is above 80 percent, they may decline the service.

The cost is $69 for iPhone 15 and iPhone 15 Pro, $79 for iPhone 14 and earlier Pro models, and $69 for standard iPhone 14 and earlier models. If your phone is under warranty or covered by AppleCare+, the replacement is free. Bring your phone and a valid ID to an Apple Store, or pack it securely if mailing it. Apple will return your phone within five to seven business days of receiving it.

Self-replacement using Apple's Self Service Repair program

Apple introduced Self Service Repair in 2022, starting with batteries. As of now, it covers iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max. You can order a battery replacement kit from apple.com/repair for around $69, which includes the battery, adhesive strips, and a pull-tab tool. You can also rent the specialized opening tool (called the iPhone Battery Replacement Kit) for $4.99 if you do not want to buy it.

The process takes about 30 to 45 minutes if you follow Apple's step-by-step guide. You will need to remove the display using heat and a suction cup, disconnect the battery connector, peel away adhesive strips holding the old battery, install the new one, and reassemble the phone. If you make a mistake—such as cracking the display or damaging the battery connector—you will have to pay for those repairs separately. This option is only worth it if you are comfortable with detailed, delicate work and have a clean, well-lit workspace.

Third-party repair shops and their trade-offs

Independent repair shops and chains like iFixit, Best Buy's Geek Squad, and local phone repair stores often charge $40 to $60 for a battery replacement—less than Apple. However, they may use non-genuine batteries, which can have shorter lifespans or cause unexpected shutdowns. Some shops offer a warranty on their work, typically 30 to 90 days, but this does not cover damage from the replacement process itself.

Before choosing a third-party shop, ask whether they use genuine Apple batteries or aftermarket ones, and request their warranty in writing. Check online reviews for that specific location, not just the chain. Keep in mind that using a non-Apple battery may affect your phone's battery health reporting in Settings—it may show as "Service Recommended" even if the battery is new.

What to do if your battery is still under warranty

If your iPhone is less than one year old and the battery has degraded to below 80 percent capacity due to a manufacturing defect, Apple will replace it for free under the standard one-year limited warranty. You can check your battery health in Settings > Battery > Battery Health & Charging. If it shows below 80 percent and your phone is within the warranty period, contact Apple Support or visit an Apple Store with your phone and proof of purchase.

If you have AppleCare+, battery replacement is free for the duration of your coverage, regardless of how much the battery has degraded. AppleCare+ costs $99 to $199 depending on your iPhone model and covers two years of accidental damage and hardware issues.

Signs your iPhone battery needs replacement

Your iPhone battery is likely due for replacement if your phone shuts down unexpectedly when the battery shows 20 to 40 percent charge, if it drains noticeably faster than it did six months ago, or if the phone feels warm during normal use. You can confirm this by checking Settings > Battery > Battery Health & Charging. If the "Maximum Capacity" percentage is below 80 percent, the battery has degraded and replacement will improve performance.

Another sign is if your phone throttles performance—meaning apps run slower or the camera takes longer to open—when the battery is low. This is Apple's way of protecting an aging battery from sudden shutdowns, but it makes the phone feel sluggish. A new battery restores full performance.

Timeline and what to expect during the repair

If you use Apple's mail-in service, the entire process takes seven to ten business days from the moment you ship your phone until it arrives back. If you visit an Apple Store with an appointment, you may wait one to three hours while they perform the replacement, or you can leave it and pick it up the same day. Third-party shops typically complete the work in 30 minutes to two hours while you wait.

During the repair, Apple will back up your data if you have not already done so, replace the battery, and run diagnostics to may support everything works. Your data and settings remain on the phone—you will not lose anything. When you get your phone back, check that the battery health shows 100 percent in Settings and that the phone no longer shuts down unexpectedly.

Frequently Asked Questions

How much does an iPhone battery replacement cost at Apple?

Apple charges $69 to $99 depending on your iPhone model. iPhone 15 models cost $69, iPhone 14 and earlier Pro models cost $79, and standard iPhone 14 and earlier models cost $69. If your phone is under warranty or covered by AppleCare+, the replacement is free.

Can I replace my iPhone battery myself if I don't have a new iPhone?

Self Service Repair is only available for iPhone 15 and newer models. For older iPhones, you will need to use Apple's service, an authorized repair shop, or a third-party repair store. Opening older iPhones to replace the battery is possible but requires specialized tools and risks damaging the phone.

Will replacing my battery void my warranty?

No. Apple's battery replacement service does not void your warranty. If you use Self Service Repair and make a mistake that damages your phone, that damage is not covered by warranty. Third-party repairs may void your warranty depending on the shop and Apple's assessment of the damage.

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 use. After that, the battery will gradually degrade. Factors like heat exposure, frequent fast charging, and leaving your phone at 0 percent for long periods can shorten battery life.

What's the difference between a genuine Apple battery and an aftermarket one?

Genuine Apple batteries are engineered to match your iPhone's power management system and typically last longer. Aftermarket batteries may work but can have shorter lifespans, show incorrect health readings, or cause unexpected shutdowns. They are usually cheaper but carry more risk.
