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

Apple will replace your iPhone battery for a fee at an Apple Store or through mail-in service. You can also take your phone to an authorized third-party repair shop. If your iPhone is still under warranty or covered by AppleCare+, the cost may be reduced or free. The process takes anywhere from same-day service at a store to one to two weeks by mail, depending on which route you choose and how busy the location is.

Opening an iPhone yourself to swap the battery is technically possible but voids your warranty, requires specialized tools, and risks damaging the screen, logic board, or battery connector. Most people find it simpler and safer to use an official or authorized repair path.

Key Takeaways

  • Apple charges between $69 and $99 for an out-of-warranty battery replacement, depending on your iPhone model.
  • AppleCare+ covers battery replacement at no cost if your battery health has dropped below 80 percent.
  • Apple Store appointments usually take one to three hours for in-store replacement, or you can mail your phone in for one to two weeks.
  • Authorized third-party repair shops often charge less than Apple and may offer faster turnaround, but verify they use genuine or quality parts.
  • DIY battery replacement requires a pentalobe screwdriver, spudger, and adhesive strips, and carries real risk of breaking your screen or internal components.

Apple Store and Apple Mail-In Battery Replacement

The official route is to visit an Apple Store or request mail-in service through Apple's website. At a store, you book an appointment through the Apple Support app or website, bring your iPhone, and a technician replaces the battery while you wait—usually one to three hours depending on how busy the location is. You pay at the time of service unless your device is under warranty or AppleCare+.

If you cannot visit a store, Apple offers mail-in service. You start a repair request on apple.com, receive a prepaid shipping label, send your iPhone to Apple, and they return it within one to two weeks. You do not pay for shipping either direction. This option works well if your nearest Apple Store is far away or if you prefer not to hand over your phone in person.

Costs vary by model. Older iPhones (iPhone 8 and earlier) typically cost $69 to replace; newer models (iPhone X and later) cost $79 to $99. If you have AppleCare+, battery replacement is covered at no cost as long as your battery health is below 80 percent. Without AppleCare+, you pay the full out-of-warranty price.

Authorized Third-Party Repair Shops

Authorized Apple repair partners—such as Best Buy's Geek Squad, carrier stores (Verizon, AT&T, T-Mobile), and independent shops certified by Apple—can also replace your battery. These shops often charge $20 to $40 less than Apple and may have faster availability. Many offer same-day service if you drop off your phone in the morning.

Before choosing a third-party shop, confirm it is officially authorized by Apple. You can search for authorized providers on Apple's website by entering your zip code. Authorized shops use genuine Apple parts and honor your warranty, whereas non-authorized shops may use aftermarket batteries that wear out faster or do not report accurate health data to iOS.

If you use a non-authorized repair shop, your warranty may be voided for that repair and potentially for future issues. The trade-off is lower cost and sometimes faster service, but you lose the may provide that comes with Apple's work.

What to Know Before You Replace Your Battery

Before you schedule a replacement, check your battery health. Go to Settings > Battery > Battery Health & Charging and look at the "Maximum Capacity" percentage. If it is above 80 percent, your battery is still in good condition and replacement is not urgent. If it is below 80 percent and you notice your phone shutting down unexpectedly or draining quickly, replacement will improve performance.

Bring your phone fully charged to your appointment or when you mail it in. If you have a passcode or Face ID enabled, you will need to unlock your phone for the technician, so be prepared to do that. Back up your data beforehand using iCloud or a computer, though the technician should not erase your phone during a battery replacement—they only swap the battery and reseal the device.

If your iPhone has physical damage—a cracked screen, water damage, or a swollen battery—the repair shop may refuse the battery replacement or charge an additional fee to fix the damage first. A swollen battery is a safety issue and should be addressed when ready; do not attempt to use or charge the phone if the back is visibly bulging.

DIY Battery Replacement: Tools, Steps, and Risks

If you decide to replace the battery yourself, you will need a pentalobe screwdriver (P2 size), a spudger or plastic pry tool, tweezers, adhesive strips or double-sided tape, and a replacement battery compatible with your iPhone model. You can buy battery kits online that include most of these tools, though quality varies widely.

The basic steps are: power off your phone, remove the two pentalobe screws at the bottom, use the spudger to gently pry up the screen from the bottom edge, disconnect the battery connector and screen cables, remove the old battery (which is glued down and requires careful heating and prying), install the new battery with fresh adhesive, reconnect the cables, and reseal the screen. The whole process takes 30 minutes to an hour for someone with experience.

The risks are significant. The iPhone screen is fragile and straightforward to crack if you pry too hard or at the wrong angle. The battery connector is small and can break if you pull at the wrong angle. The screen cable is delicate and can tear. If anything goes wrong, you may end up with a phone that does not turn on, a screen that does not respond to touch, or a battery that does not charge. Repair shops charge $200 to $400 to fix these mistakes, which is far more than the original battery replacement cost.

DIY replacement also voids your warranty when ready. If something else fails in your phone later, Apple will not cover it under warranty because you opened the device. For most people, the $69 to $99 cost of professional replacement is worth the safety and warranty protection.

How Long a New Battery Lasts and When to Replace Again

A new iPhone battery is designed to retain 80 percent of its capacity after 500 full charge cycles. A charge cycle is one complete discharge from 100 percent to 0 percent, though partial charges count toward cycles too. In real-world use, this typically means two to three years before the battery degrades noticeably.

After replacement, your new battery will show 100 percent maximum capacity in Settings > Battery > Battery Health & Charging. Over time, it will decline by roughly 1 percent per month with normal use. When it drops below 80 percent again, you will notice the phone draining faster or shutting down unexpectedly, and you can consider another replacement.

If you replace your battery every two to three years and keep your phone for five to six years total, you will likely need two battery replacements over the phone's life. This is normal wear and much cheaper than buying a new phone.

Frequently Asked Questions

Does Apple replace batteries for free?

Apple replaces batteries at no cost if your phone is under the one-year limited warranty and the battery is defective, or if you have AppleCare+ and the battery health is below 80 percent. Otherwise, you pay $69 to $99 depending on your model. Authorized third-party shops may charge less.

Can I replace my iPhone battery myself without voiding the warranty?

No. Opening your iPhone yourself voids the warranty when ready. Only Apple and authorized repair partners can replace your battery while keeping your warranty intact. If you open the phone yourself and something else breaks later, Apple will not cover it.

How do I know if my iPhone battery needs replacing?

Check Settings > Battery > Battery Health & Charging. If maximum capacity is below 80 percent, the battery is degraded. You may also notice your phone draining quickly, shutting down unexpectedly, or running slowly. Any of these signs mean replacement will improve performance.

How long does an iPhone battery replacement take at an Apple Store?

In-store replacement usually takes one to three hours, depending on how busy the location is. Mail-in service takes one to two weeks from the time you ship it until it arrives back. Some authorized third-party shops offer same-day service if you drop off your phone early in the day.

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

Genuine Apple batteries are made to Apple's specifications and report accurate health data to iOS. Third-party batteries are cheaper but may degrade faster, report incorrect health percentages, or trigger warning messages in iOS. Authorized repair shops use genuine parts; non-authorized shops may use aftermarket batteries.
