Yes, iPhone batteries can be replaced, but where and how you do it matters

Every iPhone battery degrades over time. After roughly 500 full charge cycles—usually two to three years of normal use—your battery will hold less charge than it did when new. Apple designs iPhones so the battery can be swapped out, but you have only a few reliable paths to get it done. You can go to Apple directly, use an Apple-authorized service provider, or visit an independent repair shop. The cost, time, and warranty coverage differ significantly depending on which route you choose.

The battery itself is not user-replaceable on any current iPhone model. It is glued into the phone, and removing it requires tools and training. Attempting to pry it out yourself risks damaging the display, logic board, or battery itself—which can be a fire hazard. That is why the official routes exist.

Key Takeaways

  • Apple and Apple-authorized service providers will replace your battery for a flat fee, usually between $50 and $100 depending on your iPhone model.
  • Battery replacement at Apple typically takes three to five business days, though some locations offer same-day service if you book ahead.
  • Independent repair shops often charge less and work faster, but the battery quality and warranty coverage vary widely by shop.
  • If your iPhone is still under warranty or covered by AppleCare+, battery replacement may be free if the battery health has dropped below 80 percent.
  • You can check your battery health yourself in Settings > Battery > Battery Health & Charging to see if replacement is worth considering.

How to check if your battery needs replacement

Before you spend money on a replacement, look at your actual battery health. Open Settings, tap Battery, then Battery Health & Charging. You will see a percentage labeled "Maximum Capacity." This tells you how much charge your battery holds compared to when it was new.

If the number is 80 percent or higher, your battery is still in good shape. If it has dropped below 80 percent, you may notice your phone shutting down unexpectedly under load, or the battery draining faster than it used to. That is the point where replacement becomes worth considering. Some people wait until it drops to 50 percent or lower; others replace it as soon as it hits 79 percent. There is no single right answer—it depends on how much the degradation bothers you.

You will also see a "Condition" line that says either "Normal" or "Service Recommended." If it says "Service Recommended," Apple's diagnostics have flagged the battery as degraded beyond normal wear, and replacement is the next step.

Getting your battery replaced at Apple

Apple replaces batteries at its retail stores and at Apple Authorized Service Providers (AASPs). To find a location near you, go to apple.com/support, select your device, and choose "Repair and Physical Damage." You can book an appointment online or call the store directly.

The cost depends on your iPhone model. As of now, out-of-warranty battery replacement ranges from $50 for older models to $100 for the newest Pro models. If your phone is still under the one-year limited warranty or covered by AppleCare+, and the battery health has dropped below 80 percent, the replacement is free. AppleCare+ also covers accidental damage, which can be useful if the battery replacement reveals other problems.

Turnaround time is typically three to five business days. Some Apple retail locations offer same-day service if you arrive early and the store is not busy, but do not count on it. If you cannot be without your phone, ask whether they can loan you a device while yours is being serviced.

Using an Apple Authorized Service Provider

Apple Authorized Service Providers are independent businesses that Apple has trained and certified to repair iPhones. They use genuine Apple parts and follow Apple's repair standards. You can find them on apple.com/support under "Find Locations" by selecting your device and entering your zip code.

Pricing is the same as Apple's official stores—$50 to $100 for out-of-warranty battery replacement. Turnaround time varies by location but is often faster than Apple retail, sometimes same-day or next-day. The warranty coverage is also the same: if you have AppleCare+, the replacement is free if the battery has degraded below 80 percent.

The main advantage of AASPs is convenience. They are often in smaller towns where Apple retail stores do not exist, and they may have shorter wait times. The main disadvantage is that quality and customer service vary by location. Before you book, read recent reviews on Google or Yelp to see what other customers experienced.

Independent repair shops and third-party batteries

Independent repair shops—sometimes called "third-party" or "non-authorized" shops—will replace your iPhone battery for less money, often $30 to $60. They work faster too, sometimes while you wait. But there are real trade-offs to understand.

The biggest issue is battery quality. Independent shops source batteries from various suppliers. Some use refurbished or aftermarket batteries that may not hold a charge as long as genuine Apple batteries. Others use genuine parts but cannot verify the supply chain. You have no way to know which you are getting until after the work is done. If the battery fails six months later, you may have limited recourse—many independent shops offer only 30 to 90 days of warranty on parts.

There is also a small risk of damage during the replacement. Removing an iPhone battery requires heating the adhesive, carefully prying the battery out, and reinstalling a new one without damaging the display or other components. Experienced technicians do this routinely, but mistakes happen. If something goes wrong, you may have to pay for additional repairs.

If you choose an independent shop, ask directly: Are you using genuine Apple batteries or aftermarket batteries? What is your warranty on the battery? Can you show me the battery packaging? Reputable shops will answer these questions without hesitation.

What happens to your data and settings

Battery replacement does not erase your data or settings. The technician removes only the battery; everything else stays in place. Your photos, messages, apps, and login information remain unchanged. You will not need to set up your phone again or restore from a backup.

Before you hand over your phone, back it up anyway—just as a precaution. Use iCloud or connect to a computer and use Finder (on Mac) or iTunes (on Windows). It takes 10 minutes and gives you peace of mind in case something unexpected happens during the repair.

Warranty and what is covered

If you have AppleCare+, battery replacement is free as long as the battery health has dropped below 80 percent. AppleCare+ costs $3 to $17 per month depending on your iPhone model and covers two accidental damage incidents per year, plus battery replacement and hardware repairs.

If you do not have AppleCare+ and your phone is still under the one-year limited warranty, battery replacement is free only if Apple's diagnostics show the battery is defective—not straightforward degraded from normal use. Normal battery degradation is not covered by the standard warranty.

After you get your battery replaced at Apple or an AASP, the replacement battery itself is covered by a 90-day limited warranty. If the new battery fails within 90 days, you can return for a free replacement. Independent shops typically offer 30 to 90 days of warranty on parts, so ask before you commit.

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 full charge cycles. For most people, that is two to three years of daily use. After that, the battery will continue to work but will degrade gradually. You can extend battery life by keeping your phone cool, avoiding extreme heat, and not letting it drain completely every day.

Can I replace my iPhone battery myself?

Technically yes, but it is not recommended. Batteries are glued in, and removing one requires heat, special tools, and steady hands. One slip can damage the display, puncture the battery (a fire risk), or break the logic board. Unless you have done this before, the cost of a professional replacement is worth avoiding the risk of a $300+ repair bill.

Will replacing the battery make my iPhone feel new again?

A new battery will restore your phone's charging speed and battery life, but it will not speed up the processor or improve performance. If your phone feels slow, the issue is likely the storage, RAM, or processor—not the battery. A battery replacement is worth doing if you are happy with your phone otherwise and just want it to hold a charge longer.

What if my iPhone battery is swollen?

A swollen battery is a safety hazard and should be replaced when ready. Do not attempt to remove it yourself. Take your phone to Apple or an authorized service provider right away. A swollen battery can leak chemicals or catch fire, so do not leave it plugged in or use it while waiting for an appointment.

Is it cheaper to buy a new iPhone than replace the battery?

Almost never. A battery replacement costs $50 to $100. A new iPhone costs $800 to $1,500. Unless your phone is very old or has other serious damage, replacing the battery is the far more cost-effective choice. Most people keep their phones for four to six years, so a $70 battery replacement halfway through is a good investment.
