You can replace an iPhone battery yourself or have Apple do it

An iPhone battery replacement costs between $69 and $99 at an Apple Store or Apple Authorized Service Provider, depending on your model. You can also buy a replacement battery and tools online and do it yourself, which costs $20 to $40 for the battery alone but requires opening your phone and risks damaging it if you make a mistake. Apple's route takes one to three days. The DIY route takes one to three hours if you follow the steps carefully.

Which option makes sense depends on whether you have the patience for a delicate repair and whether you want a warranty on the work. Most people choose Apple's service because the risk of breaking something else is low and you get a may provide. But if your phone is old, you are comfortable with small repairs, or you cannot afford the Apple price, the DIY path is possible.

Key Takeaways

  • Apple charges $69 to $99 to replace your battery and usually finishes in one to three days, with a warranty on the repair.
  • A DIY battery replacement costs $20 to $40 for the battery and tools but requires opening your phone and risks cracking the screen or damaging internal parts.
  • You need a pentalobe screwdriver, spudger, and suction cup to open most iPhones — these come in kits online for under $15.
  • The battery is glued down and connected to the logic board, so removing it without breaking the adhesive strips or connector takes patience and the right technique.
  • Apple's service is the safer choice unless you have done phone repairs before or your phone is too old to justify the cost.

Getting a battery replacement from Apple

Visit apple.com/support or call Apple Support to check your phone's battery health first. Open Settings, go to Battery, then Battery Health & Charging. If your maximum capacity is below 80 percent, Apple will replace the battery. If it is above 80 percent, Apple may decline unless the battery is failing in other ways — for example, if your phone shuts down at 20 percent charge.

Once you confirm your phone qualifies, schedule a repair at an Apple Store or find an Apple Authorized Service Provider near you through apple.com/support/repair. Bring your phone and a photo ID. Apple will back up your data before the repair, replace the battery, and test it before handing the phone back. The repair comes with a 90-day warranty on the battery and the work.

The cost varies by model. An iPhone 15 battery replacement is $69. An iPhone 14 Pro Max is $99. Older models like the iPhone 11 or iPhone XS are usually $69. Ask the price when you schedule, because it depends on your exact model.

Doing a DIY battery replacement

Before you start, back up your phone to iCloud or a computer. Then power it off completely. You will need a pentalobe screwdriver (the five-pointed star shape Apple uses), a plastic spudger, a suction cup, and tweezers. Buy a kit online — search "iPhone battery replacement kit" and you will find sets with all four tools plus a replacement battery for $25 to $40. The battery itself costs $15 to $25 if you buy it separately.

The first step is removing the screen. Use the suction cup on the bottom of the phone and pull gently while heating the edges with a heat gun or hair dryer on low for 30 seconds. This softens the adhesive. Once there is a small gap, slide the spudger around the edge to break the seal. This is the most fragile part — if you pull too hard, the screen cracks. Take your time.

Once the screen is off, you will see the battery connector at the top of the phone, near the speaker. Disconnect it by gently prying the connector straight up with the spudger. The battery itself is stuck down with adhesive strips underneath. Pull the strips slowly and at an angle — they should come out without tearing. If a strip breaks, use the spudger to scrape the remaining adhesive off the battery. Do not scrape the phone itself, because you can damage the logic board.

Slide the new battery in, reconnect the battery connector, and press it down firmly. Then reattach the screen by pressing it down evenly from the center outward. The adhesive on the screen's edge will hold it, but it takes a few seconds of pressure. Power the phone on and check that the battery percentage shows correctly in Settings.

What can go wrong with a DIY replacement

The most common mistake is cracking the screen while opening the phone. If you rush or use too much force on the suction cup, the glass breaks. A replacement screen costs $200 to $400, which wipes out any savings from doing the battery yourself. Heat the edges longer and pull more gently.

The second mistake is breaking the battery connector. This small plastic piece at the top of the phone connects the battery to the logic board. If you pry it too hard or at an angle, it snaps off and the phone will not recognize the battery. You cannot solder it back easily without specialized equipment. Pry straight up, not sideways.

The third issue is leaving adhesive residue on the battery or the phone. If you do not clean it off before installing the new battery, the battery will not sit flat and the screen may not close properly. Use a plastic spudger to scrape old adhesive, not a metal tool that can scratch the logic board.

When to choose Apple over DIY

If your phone is less than five years old and still worth $300 or more, Apple's service is the better choice. The $69 to $99 cost is small compared to the risk of a $200 to $400 screen replacement if something goes wrong. You also get a warranty, so if the battery fails within 90 days, Apple replaces it for free.

If your phone is older, worth less than $200, or you have replaced phone batteries before, DIY makes more sense. You save money and you already know the risks. But if this is your first phone repair, watch a full video walkthrough for your exact model before you start. Different iPhone generations have slightly different layouts, and a video will show you exactly where the connector is and how much force to use.

How long a new battery lasts

A new iPhone battery is designed to retain 80 percent of its capacity after 500 full charge cycles. One charge cycle is when you use 100 percent of the battery's power, whether in one day or spread across several days. In real use, most people see a new battery last three to four years before it drops below 80 percent capacity.

To extend battery life, avoid letting your phone get too hot, charge it before it drops below 20 percent, and use optimized battery charging in Settings. This feature slows charging to 80 percent overnight and finishes the last 20 percent right before you wake up, which reduces stress on the battery. None of these steps will make a battery last forever, but they add a year or more to its useful life.

Frequently Asked Questions

How do I know if my iPhone battery needs replacing?

Open Settings, tap Battery, then Battery Health & Charging. If maximum capacity is below 80 percent, the battery is degraded. If your phone shuts down suddenly even though the battery shows 20 or 30 percent, that is also a sign the battery is failing. Apple will replace it in either case.

Can I replace the battery myself if my phone is water-resistant?

Yes, but you will lose the water resistance seal when you open it. The screen has a rubber gasket that keeps water out. Once you remove and reattach the screen, that gasket is no longer reliable. Your phone will still work in light rain, but it is no longer rated for submersion. If water resistance matters to you, use Apple's service.

What if I break the screen while opening the phone?

You can still replace the battery, but you will also need to replace the screen. A screen replacement costs $200 to $400 depending on your model. If you break the screen, you can either pay for both repairs or take the phone to Apple and have them do both at once, which usually costs less than buying parts separately.

Does Apple use the same battery as third-party kits?

Apple uses batteries made by companies like TSMC and Sunwoda, the same manufacturers that supply third-party kits. The battery itself is often identical. The difference is that Apple tests the battery before installation and guarantees it for 90 days. Third-party batteries come with a warranty from the seller, which is usually shorter and harder to claim.

How long does an Apple battery replacement take?

If you schedule an appointment at an Apple Store, the repair usually takes one to three days. Some stores can do it same-day if they have the battery in stock and are not busy. Call ahead or check the Apple Support website to see the estimated wait time for your location.
