Yes, you can replace an iPhone battery, but where you do it matters

You can replace an iPhone battery through Apple, an Apple Authorized Service Provider, or an independent repair shop. Apple charges between $69 and $99 depending on your model, takes one to two business days, and backs the work with a one-year warranty. Independent shops often cost less and work faster, but quality varies widely and you lose any remaining manufacturer coverage. The choice depends on whether you prioritize warranty protection, speed, or cost.

Before you replace the battery, check whether your phone is still under warranty or covered by AppleCare+. If it is, battery replacement may be free or heavily discounted if the battery has degraded below 80 percent capacity. You can see your battery health in Settings > Battery and Device Care > Battery Health (on newer iPhones) or Settings > Battery > Battery Health & Charging (on older models).

Key Takeaways

  • Apple charges $69 to $99 for battery replacement and completes the work in one to two business days at most locations.
  • Battery replacement is free under AppleCare+ if your battery has degraded below 80 percent capacity, or free under warranty if the degradation is a manufacturing defect.
  • Independent repair shops typically charge $30 to $60 and can often complete the work same-day, but quality and warranty coverage vary.
  • Replacing the battery yourself using a kit is possible but voids your warranty, risks damage to other components, and requires tools and skill most people do not have.

Apple's battery replacement service and pricing

Apple replaces batteries at its retail stores and through mail-in service. You can start the process by visiting apple.com/support, selecting your device, choosing "Battery and Charging," and then selecting "Battery Replacement Service." You can also call Apple Support at 1-800-MY-APPLE or walk into an Apple Store and ask for a Genius Bar appointment.

Pricing is fixed: $69 for iPhone 11 and earlier, $79 for iPhone 12 through iPhone 14, and $99 for iPhone 15 and later. If you have AppleCare+, the service is free. If your phone is still under the one-year limited warranty and the battery has degraded due to a manufacturing defect rather than normal use, Apple replaces it at no charge — but you will need to prove the degradation is not from physical damage or liquid exposure.

Apple's mail-in service ships you a box, you send your phone in, and Apple returns it within five to seven business days. In-store service is faster: most locations complete battery replacement within one to two business days, though busy stores may take longer. Apple uses genuine parts and guarantees the work for one year.

Independent repair shops: speed and cost trade-offs

Independent repair shops charge $30 to $60 for battery replacement and often complete the work same-day or within a few hours. Many shops in malls, downtown areas, and shopping centers advertise battery replacement prominently because it is one of their most common repairs. The appeal is obvious: lower cost and faster turnaround than Apple.

The downside is inconsistency. Some independent shops use genuine Apple batteries; others use third-party batteries that may not hold a charge as long or may swell over time. Some technicians are skilled and careful; others rush the job and damage the screen or logic board in the process. You have no way to verify quality before you hand over your phone, and most independent shops offer no warranty on the work itself.

If you choose an independent shop, ask whether they use genuine or third-party batteries, how long they warranty the replacement, and whether they have online reviews on Google or Yelp. A shop willing to answer these questions directly is usually more trustworthy than one that deflects. Avoid shops that pressure you to decide on the spot or refuse to show you the old battery after removal.

DIY battery replacement kits: why most people should not attempt this

Battery replacement kits cost $20 to $40 and include a replacement battery, adhesive strips, and tools like a pentalobe screwdriver and plastic pry tools. iFixit and Amazon both sell kits with video guides. On the surface, this looks like the cheapest option.

In practice, DIY battery replacement is difficult and risky. The battery is glued to the phone's interior with strong adhesive, and prying it out without damaging the logic board or battery connector requires patience and a steady hand. If you slip, you can crack the screen from the inside, bend the battery (which can cause a fire), or disconnect a ribbon cable that controls Face ID or the camera. Once you open the phone, you also void any remaining warranty coverage, including AppleCare+.

The tools in a kit are cheap and often break or slip. A pentalobe screwdriver that costs $3 is not the same as a precision tool a technician uses daily. If something goes wrong mid-repair, you are stuck with a partially disassembled phone and no recourse. For most people, the $30 to $60 saved is not worth the risk of a $300 to $800 repair bill if something breaks.

How to prepare your phone before battery replacement

Back up your data before you take your phone in for service. Use iCloud (Settings > [Your Name] > iCloud > iCloud Backup) or connect to a computer and use Finder (Mac) or iTunes (Windows). Most repair shops do not erase your phone during battery replacement, but backups protect you if something unexpected happens.

Disable Find My iPhone before you hand over your phone. Go to Settings > [Your Name] > Find My > Find My iPhone and turn it off. If you do not, the repair shop may not be able to complete the work without your Apple ID password, which can delay service by hours or days.

If your phone has a screen protector or case, remove it before you arrive. Repair shops sometimes need to remove the screen to access the battery, and a protector or case can get in the way. Bring your phone charger so the technician can test the battery after installation.

What happens to your old battery

Apple recycles old batteries through its trade-in and recycling program. When you replace a battery at an Apple Store or through mail-in service, Apple removes the old battery and sends it to a recycling facility where lithium and other materials are recovered. You do not pay extra for this, and you cannot keep the old battery.

Independent repair shops handle old batteries differently. Some recycle them responsibly; others may not. If you care about environmental impact, ask the shop what they do with the old battery before you authorize the replacement. A shop that can answer this question clearly is more likely to handle the rest of the repair carefully too.

Signs your battery needs replacement

Your battery needs replacement if your phone shuts down at 20 or 30 percent charge, drains noticeably faster than it did a year ago, or swells visibly (the back of the phone bulges or the screen lifts slightly). Check Settings > Battery and Device Care > Battery Health to see the percentage. If it shows below 80 percent, the battery has degraded and replacement will improve performance.

A phone that is two to three years old and used daily will almost always show battery degradation. This is normal wear, not a defect. Lithium batteries lose capacity with every charge cycle, and by design they are meant to be replaced eventually. If your battery is below 80 percent and you use your phone heavily, replacement is worth the cost because a fresh battery restores the phone's speed and responsiveness.

Frequently Asked Questions

How long does a new iPhone battery last?

A new battery is designed to retain 80 percent of its capacity after 500 charge cycles, which is roughly one to two years of daily use depending on how often you charge. After that, capacity declines gradually. Most people notice a significant difference in battery life after three to four years of daily use.

Will replacing the battery fix my phone if it is slow?

If your phone is slow and your battery health is below 80 percent, a new battery may help. iPhones throttle performance when the battery is degraded to prevent unexpected shutdowns. A fresh battery removes this throttling. If your battery health is above 80 percent, slowness is likely caused by something else, and battery replacement will not fix it.

Can I replace the battery myself without voiding the warranty?

No. Opening your phone voids the manufacturer warranty and AppleCare+ coverage when ready. If you replace the battery yourself and then damage another component, Apple will not cover the repair. Only Apple and Apple Authorized Service Providers can replace the battery while preserving warranty coverage.

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

Genuine Apple batteries are manufactured to Apple's specifications and tested to hold their charge longer. Third-party batteries are cheaper but may degrade faster, hold less charge, or swell over time. You cannot always tell the difference by looking, which is why independent shops vary in quality.

Should I replace the battery or buy a new phone?

If your phone is two to four years old and works otherwise, battery replacement is usually cheaper and faster than buying a new phone. A $70 to $100 battery replacement extends the life of a $400 to $1000 phone by one to two years. Buy a new phone only if the battery is the last problem — if the screen is cracked, the camera is broken, or the phone is five years old or more.
