You can replace an iPhone battery yourself with the right tools, or have Apple do it for a flat fee

Apple charges a fixed price to replace your battery — usually between $69 and $99 depending on your model — and the work takes three to five business days at an Apple Store or authorized service provider. If you want to do it yourself, you will need a pentalobe screwdriver, a suction cup, plastic pry tools, and a replacement battery that matches your exact iPhone model. The process takes 30 minutes to an hour if you follow the steps carefully, but opening the phone risks cracking the screen or damaging internal components if you slip.

Your choice depends on whether you trust your own hands with small electronics, whether you have the tools already, and whether you want a warranty on the work. Apple's service comes with a may provide; a DIY replacement does not.

Key Takeaways

  • Apple's battery replacement costs $69 to $99 and takes three to five business days, with a warranty on the work.
  • A DIY replacement requires a pentalobe screwdriver, suction cup, plastic pry tools, and a battery kit specific to your iPhone model.
  • Opening the phone yourself voids any remaining warranty and risks cracking the screen or damaging the logic board if tools slip.
  • Third-party repair shops often charge less than Apple but may use non-original batteries and offer no manufacturer warranty.

Apple's Battery Replacement Service and Cost

Apple replaces batteries at any Apple Store or through their mail-in repair service. You can start the process by visiting apple.com/support, selecting your device, and choosing "Battery Service." Apple will ask you to describe the issue and then direct you to book an appointment or arrange a mail-in repair. If you mail the phone, Apple covers return shipping both ways.

The flat fee is $69 for iPhone 11 and earlier models, and $79 for iPhone 12 and later. This price includes the battery itself, labor, and a 90-day warranty on the repair. If your phone is still under AppleCare+, battery replacement is covered at no cost as long as the battery has lost less than 80 percent of its original capacity. Check your coverage at apple.com/support by entering your serial number.

Turnaround time at a physical store is usually same-day or next-day if you book an appointment. Mail-in service takes five to seven business days total, including shipping time. During the wait, you lose access to your phone unless you have a backup device.

What You Need to Replace the Battery Yourself

A complete DIY kit includes a pentalobe P2 screwdriver (the five-pointed bit that opens iPhones), a suction cup to lift the screen, plastic pry tools or spudgers to separate components without scratching them, tweezers, and a replacement battery designed for your exact iPhone model. Kits are sold on Amazon and other retailers for $20 to $40, often bundled with all tools included.

The battery itself must match your model number exactly. An iPhone 13 battery will not work in an iPhone 13 Pro, and using the wrong battery can cause the phone to shut down unexpectedly or not charge properly. Before you order, look up your iPhone model in Settings > General > About, then search for a kit labeled for that specific model.

You will also need a clean, well-lit workspace — a desk or table with a lamp — and a small container to hold the screws you remove. Many people use a muffin tin or ice cube tray with one screw per compartment so they do not lose track of which screw goes where.

Step-by-Step Process for Replacing the Battery

Start by powering off your iPhone completely. Then use the pentalobe screwdriver to remove the two screws at the bottom of the phone on either side of the charging port. Place these screws in your container when ready — they are straightforward to lose and hard to replace.

Wet the suction cup and press it firmly to the screen, then pull gently upward while using a plastic pry tool to work the edge of the screen away from the body. Work slowly around all four sides; the screen is glued down and will resist. Once you have a gap large enough, slide the pry tool around the perimeter to separate the adhesive. This step takes the longest and requires patience — rushing risks cracking the screen.

Once the screen is free, you will see the battery connector at the top of the phone. Use your plastic tool to gently pry the connector upward and away from the logic board. This disconnects the battery from power so you can safely remove it. Next, peel away the adhesive strips holding the battery in place — they are usually white or clear plastic tabs. Pull slowly at an angle; if they tear, use a plastic tool to scrape away the remaining adhesive.

Slide the new battery into the empty space, making sure it sits flat. Reconnect the battery connector by pressing it down firmly until it clicks. Then reconnect the screen by pressing it down around all edges until the adhesive seals. Power on the phone and check that the battery percentage appears in the status bar. If it does not, the connector may not be fully seated — power off and try again.

Risks and Limitations of DIY Battery Replacement

The most common mistake is cracking the screen while prying it open. The adhesive is strong, and if you rush or use too much force, the glass breaks. A replacement screen costs $200 to $400, which erases any savings from doing the battery yourself. The second risk is damaging the battery connector or the logic board with your tools. If the connector breaks, the phone will not recognize the new battery, and repair becomes expensive.

A DIY replacement also voids any remaining manufacturer warranty. If something else fails in your phone within the next year, Apple will not cover it under warranty because you opened the device. AppleCare+ coverage may also be voided, depending on the damage Apple finds during inspection.

Finally, opening the phone exposes internal components to dust and moisture. If you work in a humid environment or do not reassemble the phone carefully, water can seep inside and damage the logic board later. Apple's service includes a clean room and proper sealing techniques that reduce this risk.

Third-Party Repair Shops as an Alternative

Independent repair shops and chains like uBreakiFix, Best Buy's Geek Squad, and local phone repair stores offer battery replacement for $40 to $80, usually faster than Apple. Many offer same-day service if you drop off the phone in the morning. However, quality varies widely — some shops use original Apple batteries pulled from recycled phones, while others use cheaper third-party batteries that may not hold a charge as long.

Ask the shop whether they use original or third-party batteries before you commit. Original batteries last longer and are less likely to cause problems, but they cost more. Third-party batteries are cheaper but may degrade faster or cause unexpected shutdowns. Also ask about their warranty — reputable shops offer at least 30 days of coverage on the battery itself.

One advantage of third-party shops is that they often do not require an appointment and can fit you in the same day. If your battery is failing and you need your phone working when ready, a local shop may be faster than waiting for an Apple Store appointment.

When to Choose Each Option

Choose Apple's service if you want a warranty, do not have the tools, or are uncomfortable opening electronics. You pay more, but the work is may provide and your phone remains under warranty. This is the safest choice if your phone is still relatively new or if you plan to keep it for several more years.

Choose DIY replacement if you have done similar repairs before, have a steady hand, and want to save money. You need to be comfortable with the risk that you might crack the screen or damage internal parts. This makes sense if your phone is older and you do not plan to keep it much longer anyway.

Choose a third-party shop if you want a middle ground — faster than Apple, cheaper than Apple, but with some warranty protection and no risk to you. Ask about their battery source and warranty before you hand over your phone.

Frequently Asked Questions

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

Apple designs iPhone batteries to retain 80 percent of their original capacity after 500 full charge cycles. In real use, this usually means two to three years before the battery noticeably degrades. You can check your battery health in Settings > Battery > Battery Health & Charging — if it shows below 80 percent, replacement will improve performance.

Can I replace the battery myself if I have never opened a phone before?

It is possible but risky. The hardest part is opening the screen without cracking it, which requires patience and a steady hand. If you have never done this type of work, watch a full video tutorial for your exact model first. Many people succeed on their first try, but some crack the screen and end up paying more than Apple would have charged.

Will replacing the battery fix my phone if it shuts down randomly?

Random shutdowns are often caused by a failing battery, so replacement usually fixes the problem. However, they can also be caused by software issues or damage to the logic board. If the shutdowns started after a drop or water exposure, the problem may not be the battery. Try restarting the phone and updating to the latest iOS version first — this solves random shutdowns in some cases.

What happens to my data when I replace the battery?

Battery replacement does not affect your data. The battery is a separate component, and replacing it does not erase anything on your phone. Your photos, messages, and settings remain unchanged whether you use Apple's service or do it yourself.

Is it safe to use my phone while the battery is being replaced?

No. You must power off the phone completely before opening it. If you try to replace the battery while the phone is on or in sleep mode, you risk damaging the logic board or the new battery. Always power off first and wait a few seconds before you start opening the phone.
