Yes, iPhone batteries can be replaced, but where you go and what you pay depends on your phone's age and condition

Apple replaces iPhone batteries at its stores and authorized repair shops. If your phone is still under warranty or covered by AppleCare+, the replacement is free. If not, you'll pay a flat fee — typically $69 for most models, though some newer iPhones cost $79. The process takes a few hours to a few days depending on whether the store has the battery in stock.

You can also have the battery replaced by independent repair shops, which often charge less than Apple but may not use genuine Apple parts. Some third-party batteries work well; others drain faster or swell over time. The trade-off is lower upfront cost against uncertainty about longevity.

If your iPhone is old enough that repair costs more than a used replacement phone, or if the battery is swelling visibly, you may want to consider whether replacing the phone makes more sense financially.

Key Takeaways

  • Apple charges $69 to $79 for an out-of-warranty battery replacement at its stores or authorized repair shops.
  • AppleCare+ covers battery replacement at no cost if the battery capacity has fallen below 80 percent.
  • Independent repair shops typically charge $30 to $50 but may use non-genuine batteries with shorter lifespans.
  • Battery replacement takes a few hours to several days depending on stock and store availability.
  • If your iPhone is more than five or six years old, the total cost of repair plus future maintenance may exceed the price of a used replacement phone.

Apple's battery replacement service and pricing

You can start a battery replacement at apple.com by selecting your device and choosing the battery service option. You'll see the price for your specific model and can book an appointment at a nearby Apple Store or Apple Authorized Service Provider. Apple will also mail you a shipping box if no store is nearby.

The standard out-of-warranty fee is $69 for iPhone 11 and earlier models, and $79 for iPhone 12 and newer. If you have AppleCare+, the service is free as long as the battery capacity has dropped below 80 percent — Apple tests this during diagnosis. If the battery is still above 80 percent, AppleCare+ doesn't cover it, and you'll pay the standard fee.

Turnaround time varies. If the store has the battery in stock, replacement usually happens the same day or within a few hours. If not, you may wait three to five business days. Mail-in service typically takes one to two weeks total.

What happens during a battery replacement

When you arrive for your appointment, Apple runs a diagnostic test to confirm the battery is the problem and to check the phone's overall health. The technician then removes the display, disconnects the old battery, and installs a new one. The display is resealed and tested before you leave.

The entire process usually takes 30 minutes to an hour if done in-store. During this time, your phone is in the shop's hands. Apple backs the replacement battery with a one-year limited warranty, so if the new battery fails within that year, they'll replace it again at no cost.

Your data stays on the phone — Apple doesn't erase it during battery replacement. However, if the technician discovers other hardware problems during diagnosis (a cracked screen, water damage, or a failing logic board), they'll tell you before proceeding, and those repairs cost extra.

Independent repair shops and third-party batteries

Repair shops outside Apple's network — including some Best Buy locations, local phone repair stores, and mail-in services — typically charge $30 to $50 for battery replacement. The lower price comes from lower overhead and sometimes from using non-genuine batteries.

Third-party batteries vary widely in quality. Some are made by the same manufacturers that supply Apple and perform nearly identically. Others are cheaper clones that may hold a charge for only a year or two, or that swell and damage the phone's internal components. There's no reliable way to know which you're getting until after the replacement.

If you choose an independent shop, ask whether they use genuine Apple batteries, OEM (original equipment manufacturer) batteries, or generic third-party batteries. Genuine Apple batteries cost more but come with the same reliability as an Apple Store replacement. OEM batteries are usually reliable but may not carry a warranty. Generic batteries are the cheapest but carry the most risk.

When battery replacement makes sense versus buying a new phone

A battery replacement costs $69 to $79 at Apple. A used iPhone from the same generation typically costs $100 to $300 depending on storage and condition. If your phone is four years old or newer and otherwise works well, replacing the battery is usually the cheaper option.

If your phone is six years old or older, the math changes. You may spend $70 on a battery now, then face screen repairs, speaker issues, or other age-related failures within the next year or two. A used phone of a newer generation might cost only $150 to $200 more and come with several more years of software support and fewer repair needs ahead.

If the battery is visibly swollen — the back of the phone is bulging or the screen is lifting — stop using it and get it replaced immediately. A swollen battery can damage the display, logic board, and other components, turning a $70 repair into a $300+ one.

How to check your iPhone's battery health

On iPhone XS and newer, go to Settings > Battery > Battery Health & Charging. You'll see the maximum capacity as a percentage. If it's below 80 percent, the battery is degraded. If it's below 50 percent, you'll notice the phone shutting down unexpectedly under load.

On iPhone 8 and earlier, the same path shows battery health but with less detail. Third-party apps like Coconut Battery can also show capacity on any iPhone, though they require a computer connection.

Battery capacity naturally declines over time. Most iPhones lose 10 to 15 percent capacity per year of normal use. If you've had your phone for three years, seeing 70 to 80 percent capacity is normal. If you're seeing 50 percent or lower after only two years, the battery may be defective, and Apple will replace it free under warranty.

Preparing for your appointment or mail-in service

Before you book, back up your phone to iCloud or your computer. While Apple doesn't erase data during battery replacement, backups protect you if something unexpected happens. You'll also need your Apple ID and password to reactivate the phone after service.

Bring your phone, a photo ID, and proof of purchase if you're claiming AppleCare+ coverage. If you don't have proof of purchase, Apple can look up your account if you bought it from an Apple Store or online at apple.com.

If you're using mail-in service, Apple will send you a prepaid shipping box. Pack the phone carefully, include a note with your contact information, and drop it at a UPS location. Don't include accessories — just the phone itself.

Frequently Asked Questions

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

Most iPhone batteries are designed to retain 80 percent of their capacity after 500 full charge cycles, which typically takes two to three years of daily use. After that, capacity declines gradually. Most people notice a significant difference by year four or five.

Can I replace the battery myself?

Technically yes, but it's difficult and risky. iPhones are glued together, and opening one requires heat, special tools, and steady hands. One slip can damage the display, logic board, or battery itself. If the battery is swollen, opening the phone can cause it to catch fire. Unless you have experience with phone repair, professional replacement is safer and often cheaper than replacing parts you damage.

Will replacing the battery fix my phone if it's slow or freezing?

Sometimes. If slowness started after the battery capacity dropped below 50 percent, a new battery may help because iOS throttles performance on degraded batteries to prevent unexpected shutdowns. If the phone was slow before the battery degraded, the problem is likely something else — storage space, too many background apps, or aging hardware — and a battery replacement won't fix it.

What's the difference between AppleCare+ and the standard warranty?

The standard one-year limited warranty covers defects, including battery failure if capacity drops below 50 percent in the first year. AppleCare+ extends coverage to two years and covers battery replacement if capacity falls below 80 percent at any point. AppleCare+ also covers accidental damage like drops and water exposure, though you pay a deductible per incident.

Can I get my old battery back after replacement?

No. Apple and most repair shops recycle old batteries rather than return them to customers. If you want to keep your old battery for any reason, ask before the replacement starts — some shops may set it aside, though they're not required to.
