Yes, you can change your iPhone battery, but your options depend on the model and whether it's still under warranty

Apple will replace your iPhone battery for a flat fee at any Apple Store or Apple Authorized Service Provider. If your phone is still covered by warranty or AppleCare+, the replacement may be free if the battery has degraded below 80 percent capacity. You can also mail your phone to Apple for a battery replacement. Outside of Apple, independent repair shops and some electronics retailers offer battery replacements, usually for less money, though this voids any remaining warranty.

The process takes anywhere from same-day service at an Apple Store to one to two weeks by mail. You'll need to back up your data first, though the technician typically doesn't erase your phone during a battery replacement. If you choose an independent repair shop, confirm they use genuine or high-quality third-party batteries—cheap replacements may fail quickly or damage your phone.

Key Takeaways

  • Apple charges a flat fee for out-of-warranty battery replacements, ranging from $49 to $69 depending on your iPhone model.
  • If your battery health is below 80 percent and your phone is under warranty or AppleCare+, Apple replaces it at no cost.
  • Independent repair shops typically charge $30 to $50 for battery replacement but may use non-genuine parts that carry unknown durability.
  • Back up your iPhone before any battery service, and expect the process to take a few hours at an Apple Store or one to two weeks by mail.
  • Replacing the battery yourself using a kit is possible but requires opening your phone and risks damage to the display or internal components.

Check your battery health before you decide

Your iPhone displays battery health information in the Settings app. Open Settings, tap Battery, then Battery Health & Charging. You'll see a percentage labeled "Maximum Capacity"—this tells you how much charge your battery holds compared to when it was new. A battery at 80 percent or higher is considered normal; below 80 percent, Apple considers it degraded.

You'll also see "Condition" information. If it says "Your battery is in good condition," you likely don't need a replacement yet. If it says "Service Recommended" or "Service Battery," the battery is degraded enough that Apple will replace it. This information matters because Apple's warranty covers battery replacement only if capacity has dropped below 80 percent within the first year, or if AppleCare+ covers your phone.

Getting a replacement at an Apple Store

Visit apple.com, click Support, and use the Repair & Service tool to find the nearest Apple Store or Apple Authorized Service Provider. You can book an appointment online or walk in, though appointments are faster. Bring your iPhone and a valid ID. The technician will confirm the battery health, discuss your options, and either replace the battery on the spot or schedule a later appointment if they're busy.

Same-day service is common at busy locations, though it may take a few hours. The technician will back up your data if needed, replace the battery, and run diagnostics to confirm the new battery works. You'll pay at the time of service. If your phone is under warranty or AppleCare+, the technician will check whether the battery replacement is covered before charging you.

Mailing your phone to Apple for battery service

If no Apple Store is nearby, you can mail your phone to Apple for battery replacement. Go to apple.com/support, select your device, and choose "Mail In Repair." Answer a few questions about your phone's condition, and Apple will email you a prepaid shipping label. Pack your iPhone in a box with padding, attach the label, and drop it at any shipping location.

Apple typically receives your phone within three to five business days, diagnoses it the same day, and ships it back within one to two weeks. You'll receive email updates at each step. The cost is the same as in-store service. This option takes longer but works if you're far from an Apple Store or prefer not to visit in person.

Using an independent repair shop

Electronics retailers like Best Buy, local phone repair shops, and mail-in repair services like iFixit or uBreakiFix offer battery replacements for $30 to $50, usually cheaper than Apple. Many can complete the work the same day. Before you choose a shop, confirm they use genuine Apple batteries or high-quality third-party batteries—ask what brand they use and whether they warranty the replacement.

The trade-off is that using a non-Apple repair shop voids any remaining manufacturer warranty on your phone. If something goes wrong during the repair, Apple won't cover it. However, reputable shops typically warranty their own work for 30 to 90 days. Read online reviews for the specific location you're considering, and ask whether they back up your data and test the new battery before returning your phone.

Replacing the battery yourself with a kit

Battery replacement kits are sold online for $20 to $40 and include a new battery, tools, and instructions. This option is the cheapest but also the riskiest. Opening an iPhone requires prying off the display, which can crack if you use too much force. You'll also need to disconnect the battery connector and remove adhesive strips holding the old battery in place. One slip with a tool can damage the logic board or other components.

If you decide to try this route, watch a video guide for your specific iPhone model first—the process differs between models. Work on a clean, flat surface with good lighting. Take photos as you go so you remember how to reassemble. If anything feels stuck or you're unsure, stop and take your phone to a repair shop instead. A cracked display or damaged connector costs far more to fix than a professional battery replacement.

What to expect after your battery is replaced

After replacement, your iPhone should charge faster and hold a charge longer. The Battery Health display will show 100 percent maximum capacity for a new battery. Your apps, photos, and settings remain unchanged—the technician only swaps the battery, not the storage.

If you used an independent shop or a DIY kit, monitor your phone for the first week. The new battery should charge normally and not overheat. If it drains unusually fast, won't charge, or gets hot, contact the shop or consider taking it to Apple for diagnosis. A faulty replacement battery is rare but possible, especially with very cheap third-party batteries.

Frequently Asked Questions

How much does Apple charge for a battery replacement?

Apple charges $49 to $69 depending on your iPhone model, with newer models costing more. If your phone is under warranty or AppleCare+ and the battery is below 80 percent capacity, the replacement is free. Out-of-warranty replacements are the flat fee with no additional charges.

Will my data be erased if I get a battery replacement?

No. A battery replacement does not erase your phone. The technician removes and replaces only the battery, leaving your apps, photos, and settings intact. You should still back up your phone before service in case something unexpected happens.

How long does a new iPhone battery last?

A new battery is designed to retain 80 percent capacity after about 500 full charge cycles, which typically takes two to three years of normal use. After that, capacity degrades gradually. Most people notice a need for replacement around three to four years of daily use.

Can I replace my iPhone battery at Best Buy?

Yes, Best Buy offers battery replacements at many locations through their Geek Squad service, usually for $40 to $60 depending on the model. You can check availability and book an appointment on bestbuy.com. Turnaround is often same-day or next-day.

What happens if I replace my battery at a non-Apple shop?

Your manufacturer warranty ends, but the repair shop typically warranties their work for 30 to 90 days. If the battery fails or causes damage after that period, Apple won't cover it under warranty. Choose a reputable shop with good reviews to reduce this risk.
