Yes, you can replace an iPhone battery, but your options depend on whether your phone is still under warranty and how much you want to spend

Apple will replace your iPhone battery for a flat fee at any Apple Store or Apple Authorized Service Provider. If your battery health has dropped below 80 percent and your phone is under warranty or covered by AppleCare+, the replacement is free. If you are out of warranty, Apple charges a set amount — typically $69 to $99 depending on your iPhone model — and the job takes one to two hours, though you can often book an appointment online and drop it off.

You can also take your phone to an independent repair shop, which usually charges less than Apple but may void any remaining warranty coverage. A third option is to buy a battery replacement kit and do it yourself, though this requires opening your phone and carries a real risk of damaging the screen, logic board, or other components if you slip.

Key Takeaways

  • Apple replaces iPhone batteries for free if your phone is under warranty or covered by AppleCare+, and charges $69 to $99 out of warranty.
  • Independent repair shops typically cost less than Apple but may not honor your warranty after the work is done.
  • You can check your battery health in Settings > Battery > Battery Health & Charging to see if replacement is worth the cost.
  • DIY battery kits exist but require opening your phone and risk permanent damage to the screen or internal components.
  • Apple's mail-in repair service is an option if no local store is convenient, though it takes longer than an in-store visit.

How to check if your battery actually needs replacing

Before you pay for a replacement, check your battery health. Go to Settings, tap Battery, then tap Battery Health & Charging. You will see a percentage labeled "Maximum Capacity" — this tells you how much charge your battery can hold compared to when it was new.

If the number is above 80 percent, your battery is still in reasonable shape. If it is between 70 and 80 percent, you may notice the phone drains faster than it used to, but replacement is optional. Below 70 percent, the phone will drain noticeably during normal use, and below 50 percent, it may shut down unexpectedly even when the battery indicator shows charge remaining.

You will also see a "Condition" line that may say "Normal" or "Service Recommended." If it says "Service Recommended," Apple considers the battery degraded enough to warrant replacement, and you should plan to have it done within a few months.

Apple Store replacement: cost, time, and warranty

An Apple Store replacement is the safest option because Apple uses genuine parts and guarantees the work. Book an appointment through the Apple Store app or website, or walk in and ask for a Genius Bar appointment. You will need your phone and a valid ID.

If your phone is under the standard one-year limited warranty and the battery health is below 80 percent, the replacement is free. If you bought AppleCare+ (which costs $99 to $379 depending on your model and covers two years of accidental damage plus battery service), battery replacement is also free. Out of warranty, you pay the service fee — $69 for iPhone 11 and older, $79 for iPhone 12 and 13, and $99 for iPhone 14 and newer — plus tax.

The job usually takes one to two hours if you wait, though you can often leave your phone and pick it up the same day. Apple backs the replacement with a 90-day warranty on the battery itself, so if it fails within that window, they will replace it again at no charge.

Independent repair shops: lower cost, higher risk

Independent repair shops like iFixit, uBreakiFix, and local phone repair stores typically charge $40 to $70 for a battery replacement, undercutting Apple's price. The work is usually done the same day, and many shops will replace your screen or other parts while they have the phone open if you ask.

The trade-off is that using a non-Apple repair shop may void any remaining manufacturer warranty. Apple's warranty explicitly excludes damage caused by unauthorized repairs, so if something else breaks after you have had the battery replaced elsewhere, Apple may refuse to cover it. Some independent shops carry genuine Apple parts, but others use third-party batteries that may not hold a charge as long.

Before you choose an independent shop, ask whether they use genuine or third-party batteries, what warranty they offer on the replacement, and whether they are certified by Apple (some are Apple Authorized Service Providers, which means Apple backs their work). Read recent reviews on Google or Yelp to check for complaints about quality or reliability.

DIY battery replacement: what you need and what can go wrong

Battery replacement kits are sold on Amazon and eBay for $15 to $40 and include a replacement battery, adhesive strips, and tools like a pentalobe screwdriver and plastic pry tools. The process involves removing the bottom screws, heating the edges to soften the adhesive, prying open the phone, disconnecting the old battery, and installing the new one.

The main risk is that the screen is glued to the frame, and if you pry too hard or in the wrong spot, you will crack it. Replacing a cracked screen costs $200 to $400 at Apple, which wipes out any savings from the cheap battery kit. You also risk damaging the logic board, battery connector, or other components if your tools slip or if you accidentally short something with a metal tool.

If you decide to try it anyway, watch a video specific to your exact iPhone model first — the process differs between models — and work slowly. Use a heat gun or hair dryer to warm the edges, not a lighter or heat source you cannot control. If you feel significant resistance, stop and take the phone to a professional instead of forcing it.

Mail-in repair through Apple

If you do not have an Apple Store nearby, you can mail your phone to Apple for battery replacement. Start a repair request on Apple's support website, choose "Mail In," and Apple will send you a prepaid shipping box. You pack the phone, drop it off at a UPS location, and Apple sends it back within five to seven business days.

The cost is the same as in-store repair — free if under warranty or with AppleCare+, otherwise $69 to $99 plus tax. The downside is that you will be without your phone for a week to ten days, and if Apple finds other damage during the inspection, they may contact you before proceeding. For most people, an in-store visit is faster if one is available.

What to do if your phone is too old for a battery replacement

Older iPhone models like the iPhone 6, 6s, and 7 are no longer supported by Apple for battery service. Apple stopped stocking parts for these models, so even if you take one to an Apple Store, they cannot replace the battery.

Your options are to use an independent repair shop (which may still have parts in stock) or to replace the phone. If the phone is otherwise working and you just need longer battery life, a portable charger is a cheap alternative — a 10,000 mAh power bank costs $15 to $30 and will charge your phone two to three times over.

Frequently Asked Questions

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

Apple designs iPhone batteries to retain 80 percent of their capacity after 500 full charge cycles. In real use, that usually means two to three years before the battery noticeably degrades. If you charge your phone every day, you will hit that point faster than someone who charges every other day.

Will replacing the battery fix my phone if it keeps shutting down?

If your phone shuts down unexpectedly even when the battery shows charge, a battery replacement will usually fix it. However, if the phone shuts down even after the replacement, the problem is likely the power management circuit on the logic board, which requires a more expensive repair or phone replacement.

Can I replace the battery myself without opening the phone?

No. The battery is glued inside the phone and cannot be accessed without opening the case. There is no external battery door on modern iPhones like there was on older Android phones.

Does AppleCare+ cover battery replacement?

Yes. AppleCare+ includes battery service, so you can get a replacement for free as long as the battery health is below 80 percent. AppleCare+ costs $99 to $379 depending on your model and covers two years from the date you buy it.

What happens to my data when the battery is replaced?

Your data stays on the phone. The battery replacement does not erase anything. However, you should back up your phone to iCloud or a computer before you take it in, just in case something unexpected happens during the repair.
