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

Apple will replace your iPhone battery for a flat fee, usually between $69 and $99 depending on your model. You can also visit an Apple Store, an Apple Authorized Service Provider, or certain third-party repair shops. If your iPhone is still under warranty or covered by AppleCare+, the replacement may be free if the battery has degraded below 80 percent capacity. The catch: Apple's official route takes one to three business days, while some third-party shops can do it the same day.

You can technically replace the battery yourself if you have the right tools and patience, but it voids your warranty and risks damaging the phone. Most people find it easier and safer to use a service, even if it costs more upfront.

Key Takeaways

  • Apple charges $69 to $99 for a battery replacement at an Apple Store or Apple Authorized Service Provider, depending on your iPhone model.
  • If your iPhone is under warranty or you have AppleCare+, battery replacement is free when capacity has dropped below 80 percent.
  • Third-party repair shops often charge less ($30 to $60) and can complete the work the same day, but may not use genuine Apple parts.
  • Self-repair requires specialized tools, voids your warranty, and risks cracking the screen or damaging internal components.
  • You can check your battery health in Settings > Battery > Battery Health & Charging to see if replacement is worth the cost.

How to check if your battery needs replacement

Open Settings, tap Battery, then tap Battery Health & Charging. You will see a percentage labeled "Maximum Capacity." This number tells you how much charge your battery holds compared to when it was new. If it is below 80 percent, the battery is degraded enough that most people notice slower performance or shorter time between charges.

You will also see "Condition" listed below the percentage. If it says "Normal," your battery is fine. If it says "Service Recommended," Apple's system has detected degradation. If it says "Service Not Available," the phone cannot read the battery properly—a sign the battery itself may be failing.

Getting a replacement at an Apple Store

Go to apple.com, click Support, and select your iPhone model. Choose "Battery Service" and select your nearest Apple Store. You can book an appointment online or walk in, though appointments are faster. Bring your phone and a valid ID.

The technician will confirm the battery capacity in front of you, then either replace it on the spot (usually within an hour for a standard battery) or order a replacement if your model requires it. You pay at the time of service. If you have AppleCare+, show your coverage proof—the replacement will be free if the battery is below 80 percent.

Using an Apple Authorized Service Provider

Apple Authorized Service Providers are independent shops certified by Apple to use genuine parts and follow Apple's repair standards. They charge the same flat fee as Apple ($69 to $99) and often have shorter wait times because they are less busy. To find one near you, go to apple.com/support, search for your location, and filter for "Authorized Service Providers."

Call ahead to confirm they have your battery model in stock and to book an appointment. Bring your phone, ID, and proof of purchase or AppleCare+ coverage if you have it. Turnaround is usually one to three business days.

Third-party repair shops and mail-in services

Independent repair shops (not Apple-certified) typically charge $30 to $60 for a battery replacement and can often do it the same day. Popular chains include iFixit, uBreakiFix, and Best Buy's Geek Squad, though prices and turnaround vary by location. The trade-off: they may not use genuine Apple batteries, and the replacement voids any remaining Apple warranty.

Mail-in services like iFixit and Puls send you a prepaid box, you ship your phone, and they return it in three to five business days. This option works if no local shop is nearby, but you lose access to your phone during the repair. Check reviews and confirm the shop's warranty on the replacement battery before you commit.

Self-repair with a kit

iFixit and other retailers sell battery replacement kits ($20 to $40) that include the battery, adhesive strips, and tools like a pentalobe screwdriver and plastic pry tools. The process involves removing the screen, disconnecting the battery connector, peeling out the old battery, and gluing in the new one. It takes 30 minutes to two hours depending on your skill level.

The risks are real: the screen is glued on and straightforward to crack, the battery connector is small and fragile, and reassembling the phone without dust inside the screen is difficult. If something goes wrong, you have a broken phone and no warranty to cover it. Apple will refuse to service a phone you have opened yourself. Self-repair makes sense only if you are comfortable with electronics and have done it before.

What happens to your old battery

Apple and Authorized Service Providers recycle your old battery as part of the service—you do not pay extra and do not have to handle it. They extract materials like cobalt and lithium for reuse. If you use a third-party shop, ask what they do with the old battery; most recycle it, but confirm before you leave.

Do not throw a lithium battery in the trash or recycling bin. If you removed the battery yourself and need to dispose of it, take it to an electronics recycling center or a Best Buy (which accepts batteries for free).

Frequently Asked Questions

Will replacing the battery fix my iPhone if it keeps shutting down?

Maybe. If your battery capacity is below 80 percent and your phone shuts down at 20 or 30 percent charge, a replacement usually fixes it. But if the phone shuts down even with a full battery, the problem is likely the power management chip or logic board, not the battery. Check Battery Health first; if it says "Normal" but the phone still shuts down, you need a different repair.

How long does a new iPhone battery last?

Apple designs batteries to retain 80 percent capacity after 500 full charge cycles. In real use, that is roughly two to three years for most people. After that, capacity drops gradually. You will likely want another replacement around year five or six, depending on how often you charge.

Can I replace the battery myself without voiding the warranty?

No. Opening your iPhone voids the warranty when ready, even if you use genuine parts. Apple's warranty covers manufacturing defects, not user-opened phones. If you self-repair and something else breaks later, Apple will refuse to fix it under warranty. AppleCare+ also does not cover damage from self-repair.

Is it cheaper to replace the battery or buy a new phone?

A battery replacement ($69 to $99) is almost always cheaper than a new phone ($800 and up). Unless your phone is five or more years old and has other hardware problems, battery replacement extends its life by two to three more years at a fraction of the cost.

What if my iPhone battery is swollen?

A swollen battery is a safety hazard and needs when ready replacement. Do not try to open the phone yourself—a swollen battery can catch fire if punctured. Take it to an Apple Store or Authorized Service Provider right away. Tell them the battery is swollen so they handle it carefully. Most places will prioritize this as an urgent repair.
