Yes, you can replace an iPhone battery, but Apple and most users go through Apple or an authorized repair shop instead of doing it at home

Apple will replace your iPhone battery for a flat fee — usually between $69 and $99 depending on your model — at any Apple Store or through mail-in service. An authorized Apple repair partner will do the same. If your phone is still under warranty or covered by AppleCare+, the cost may be lower or free. That is the route most people take because it takes one to three days, carries no risk to the rest of your phone, and comes with a may provide.

You can buy a replacement battery online and swap it yourself, but it requires opening your phone, disconnecting the display, removing the old battery, and reassembling everything. The tools cost $15 to $30, the battery itself runs $20 to $40, and one mistake — a torn ribbon cable, a cracked screen, a short circuit — can cost you $200 to $400 in additional repairs. Most people who try it at home either succeed and save $50 to $60, or damage something and end up paying more than Apple would have charged.

Key Takeaways

  • Apple charges $69 to $99 to replace your battery at an Apple Store or through an authorized repair partner, and the work takes one to three days.
  • A DIY battery replacement costs $35 to $70 in parts and tools but requires opening your phone and risks damaging the display, logic board, or battery connector if you slip.
  • iPhones are glued shut, not screwed together, so you need a heat gun or hair dryer, a suction cup, and plastic pry tools — not a screwdriver.
  • If your battery health has dropped below 80 percent and your phone is under warranty or covered by AppleCare+, Apple may replace it at no cost.
  • Third-party repair shops (not Apple-authorized) often charge $40 to $60 but may use non-Apple batteries that degrade faster or trigger warning messages.

What you need to know about Apple's battery replacement service

Apple replaces batteries at any Apple Store without an appointment if you walk in during business hours, though you may wait. You can also book a Genius Bar appointment online through the Apple website or app, which usually gets you in within a few days. Mail-in service is available if no store is near you — you pack your phone, ship it to Apple, and they send it back within a week.

The cost depends on your model. An iPhone 15 battery replacement is $69; an iPhone 14 or 13 is $69; older models like the iPhone 12 or 11 are also $69. If your phone is under the one-year limited warranty and the battery is genuinely defective (not just worn out from normal use), Apple replaces it free. If you have AppleCare+, battery replacement is covered at no cost as long as the battery health has dropped below 80 percent.

Apple will also run a battery health check for free. You go to Settings > Battery > Battery Health & Charging, and the phone shows you the maximum capacity as a percentage. If it is 80 percent or higher, Apple considers it normal wear. Below 80 percent, you are a candidate for replacement.

How to do a DIY battery replacement and what can go wrong

The process starts with heat. iPhones are sealed with adhesive, not screws, so you use a heat gun, hair dryer, or heat pad to warm the edges of the phone for two to three minutes. This softens the glue enough to pry the screen away. You then use a suction cup to pull the screen up slightly, slide a plastic pry tool into the gap, and work your way around the edge. The display is connected to the logic board with ribbon cables, so you have to disconnect those before you can fully remove the screen.

Once the screen is off, you can see the battery. It is also glued down and connected with a battery connector — a small plug you have to unplug before you can remove the old battery. You peel away the adhesive strips, pull the battery out, insert the new one, plug in the connector, and reassemble in reverse. The whole job takes 30 to 60 minutes if you have done it before, and 90 minutes to two hours if you are doing it for the first time.

The risks are real. If you pull the screen too hard, you crack the display — a $200 to $300 repair. If you slip with the pry tool and puncture the battery, it can catch fire or damage the logic board. If you disconnect a ribbon cable wrong or don't seat it fully, the screen or Face ID stops working. If you reassemble the phone and leave a gap, dust gets in and causes problems later. Most people who attempt this succeed, but the margin for error is small.

What tools and parts you need for a home battery replacement

A basic DIY kit includes a heat gun or hair dryer, a suction cup, plastic pry tools (metal can damage the phone), a spudger (a flat plastic tool for disconnecting cables), and tweezers. These tools together cost $15 to $30 on Amazon or at electronics retailers. The replacement battery itself — a genuine Apple battery or a high-quality third-party battery — costs $20 to $40 depending on your model and the seller.

You also need a clean, well-lit workspace and a way to keep track of small screws and parts. Many people use a magnetic mat or a small container divided into sections. If you lose a screw or a bracket, you can order replacements, but it adds time and cost.

Before you start, watch a video walkthrough for your specific iPhone model. iFixit and YouTube both have detailed guides with close-up shots. Every model is slightly different — the iPhone 15 layout is not the same as the iPhone 13 — so following the exact steps for your phone matters.

Third-party repair shops and what to expect

Independent repair shops that are not Apple-authorized often charge $40 to $60 for a battery replacement and can do it the same day. The trade-off is that some use non-Apple batteries, which may not perform as well or last as long. A non-Apple battery might show a "Unable to verify this iPhone has a genuine Apple battery" message in Settings, and it may degrade faster or not report its health accurately.

If you choose a third-party shop, ask whether they use Apple batteries or third-party batteries, and whether they offer a warranty on the replacement. A reputable shop will stand behind the work for at least 30 days. Avoid shops that cannot or will not answer these questions.

When a DIY replacement makes sense and when it does not

A DIY replacement makes sense if you are comfortable working with small electronics, you have a clean workspace, you have watched a full video guide for your model, and you can afford to pay for a professional repair if something goes wrong. It also makes sense if you live far from an Apple Store and do not want to mail your phone in.

A DIY replacement does not make sense if your phone is still under warranty or covered by AppleCare+, because you lose the coverage by opening it. It does not make sense if you are in a hurry — a mistake will cost you more time and money than waiting for Apple. And it does not make sense if you are not confident in your ability to follow detailed instructions, because the cost of a mistake is high.

Frequently Asked Questions

Will opening my iPhone void the warranty?

Yes. Opening your phone yourself voids the limited warranty and AppleCare+ coverage. If something else breaks during the replacement or shortly after, Apple will not cover it. If your phone is still under warranty, have Apple replace the battery instead.

Can I use a non-Apple battery in my iPhone?

Yes, but it may trigger a warning message and may not report its health accurately in Settings. Non-Apple batteries often degrade faster. If you use one, buy from a reputable seller with good reviews, and expect the battery to last shorter than an Apple battery would.

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 is usually two to three years. After that, the battery degrades gradually. You do not have to replace it when ready — you can keep using your phone — but performance may slow down as the battery weakens.

Is it cheaper to replace the battery or buy a new phone?

A battery replacement costs $69 to $99 through Apple. A new iPhone costs $800 to $1,200. Unless your phone is very old or has other damage, replacing the battery is far cheaper and extends the life of your current phone by two to three years.

Can I replace the battery on an older iPhone model?

Yes. Apple will replace batteries on any iPhone model that is still in use, though older models may have higher battery costs or longer wait times. DIY replacement is also possible on older models, but the process varies — always check a guide for your specific model before you start.
