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

You can have an iPhone battery replaced through Apple, an Apple Authorized Service Provider, or an independent repair shop. Apple will replace the battery in any iPhone model, though the cost and turnaround time depend on whether your phone is under warranty or AppleCare+. Independent shops often charge less and work faster, but the quality and warranty on their work varies widely.

The key difference is that Apple uses genuine Apple parts and maintains your device's water resistance seal, while independent shops may use third-party batteries that work fine but carry different risks. Your choice depends on cost, speed, and how much you trust the shop doing the work.

Key Takeaways

  • Apple replaces iPhone batteries for a flat fee (usually $69 to $99 depending on model), or free if your phone is under warranty or AppleCare+ covers battery service.
  • Apple Authorized Service Providers offer the same genuine parts and warranty as Apple stores, but availability depends on your location.
  • Independent repair shops typically charge $30 to $60 and work faster, but use third-party batteries that may not last as long or hold their warranty.
  • You can check your battery health in Settings > Battery > Battery Health & Charging to see if replacement is worth doing now.
  • Removing and replacing an iPhone battery yourself is possible but voids your warranty and risks damaging the screen, logic board, or water resistance seal.

How to check if your battery needs replacement

Open Settings, tap Battery, then tap 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 it is below 80 percent, Apple considers the battery degraded. If it is below 50 percent, the phone may shut down unexpectedly even when the battery shows charge remaining.

You will also see a "Condition" line that says either "Normal", "Service Recommended", or "Service Not Available Yet". If it says "Service Recommended", Apple's system has detected a problem and replacement is the right move. If it says "Normal" but your maximum capacity is below 80 percent, the battery is aging normally and you can decide whether the reduced runtime bothers you enough to replace it.

Getting a battery replaced at Apple

Go to apple.com/support or call Apple Support to schedule a Genius Bar appointment at an Apple Store, or mail your phone to Apple for service. You will need your device and a valid ID. Apple will run a diagnostic to confirm the battery is the problem, then replace it while you wait (usually 1 to 2 hours) or ship it back to you in 3 to 5 business days if you mail it in.

The cost is $69 for iPhone 15, $79 for iPhone 14 and earlier models, and $99 for iPhone 11 Pro and Pro Max — though the exact price varies slightly by region. If your phone is under the one-year limited warranty and the battery is defective, replacement is free. If you have AppleCare+, battery service is free as long as the battery capacity has dropped below 80 percent or the Condition line says "Service Recommended".

Using an Apple Authorized Service Provider

Apple Authorized Service Providers are independent businesses certified by Apple to perform repairs using genuine Apple parts. They follow the same standards as Apple Stores and offer the same warranty on the battery replacement. You can find one near you by going to apple.com/support, clicking "Find Locations", and filtering for Authorized Service Providers.

Turnaround time and pricing vary by location, but most charge the same flat fee as Apple and can often fit you in faster than an Apple Store. Call ahead to confirm they have your iPhone model in stock and ask whether they can do the work same-day or if you need to leave the phone overnight.

Independent repair shops and third-party batteries

Independent repair shops typically charge $30 to $60 for a battery replacement and can often do the work the same day. They use third-party batteries made by companies like Anker, Spigen, or generic manufacturers — these batteries work and hold a charge, but may not last as long as Apple's original battery or maintain the same capacity over time.

The main risk is that an independent shop may not reseal your phone's water resistance properly after opening it, which can lead to water damage months later. Ask the shop whether they use a pressure test or water resistance test after reassembly, and whether they warranty their work if the phone develops water damage. Get the warranty terms in writing before you hand over your phone.

Replacing the battery yourself

You can buy a replacement battery kit online (usually $20 to $40) that includes the battery, adhesive strips, and tools like a pentalobe screwdriver and plastic pry tools. iFixit and other repair sites publish step-by-step guides with photos for most iPhone models. The process takes 30 minutes to an hour if you follow the guide carefully.

The downsides are significant: opening your iPhone yourself voids any remaining warranty, and one slip with a pry tool can crack the screen or damage the logic board. You also need to reapply adhesive strips correctly to restore water resistance, which is harder than it sounds. Unless you have done phone repairs before, this route is riskier than it is worth — the money you save is small compared to the cost of fixing a cracked screen or water damage.

What happens after your battery is replaced

After replacement, your phone's maximum capacity will reset to 100 percent (or close to it). Your battery health will be tracked from that point forward, and you will see the capacity drop gradually over the next two to three years as the new battery ages. This is normal and does not mean the replacement was defective.

If you had AppleCare+, the replacement battery is covered and you do not need to do anything. If you paid out of pocket, keep your receipt — Apple's battery replacement comes with a 90-day limited warranty on the battery itself, and Authorized Service Providers typically offer a one-year warranty on their work.

Frequently Asked Questions

How long does a battery replacement take?

At an Apple Store, usually 1 to 2 hours if you wait, or 3 to 5 business days if you mail it in. Independent shops often finish same-day. Mail-in service through Apple takes the longest but is an option if no store is nearby.

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

Only if the slowness or crashes are caused by battery degradation. iPhones throttle performance when the battery is very old to prevent unexpected shutdowns. If your battery health is below 50 percent, replacement may help. If it is above 80 percent, the problem is likely something else and a battery replacement will not fix it.

Can I use my phone while the battery is being replaced?

No. If you go to an Apple Store, you will need to leave your phone for the duration. If you mail it in, you will be without your phone for several days. Plan ahead and consider backing up your data before you drop it off.

What if my battery fails again after replacement?

If you had the work done at Apple or an Authorized Service Provider, the replacement battery is warranted. Contact the place that did the work and explain the issue — they will replace it again at no charge if the failure is within the warranty period (usually 90 days to one year).

Is it worth replacing the battery if my phone is old?

If your phone is more than 5 or 6 years old, a new battery may not be worth the cost — you might be better off upgrading. But if your phone works fine otherwise and you want to keep it, a $70 battery replacement is much cheaper than a new phone and can add another year or two of usable life.
