You can replace an iPhone battery yourself if your model is designed for it, or have Apple do it for a flat fee

Whether you can replace your own iPhone battery depends on which model you own. Starting with iPhone 15 (released in 2023), Apple designed iPhones so the battery can be removed without tools by the owner—you heat the phone, peel back the battery, and slide out the old one. Older models require opening the phone with a pentalobe screwdriver and disconnecting cables, which risks damage to the display and logic board if you slip. For any iPhone, Apple will replace the battery for a set price, usually between $50 and $80 depending on the model, and your phone stays under warranty during the repair.

The choice comes down to your comfort level, your phone's age, and whether you want a may provide. If your iPhone is still under warranty or AppleCare+, battery replacement may be covered at no cost if the battery health has dropped below 80 percent. If you own an iPhone 15 or later and feel confident following video instructions, a DIY replacement takes 20 to 30 minutes and costs $20 to $40 for a replacement battery. For any other model, or if you want professional installation, an Apple Store or authorized repair shop is the safer route.

Key Takeaways

  • iPhone 15 and newer models have user-removable batteries that require heat, a plastic tool, and no screwdrivers—the process takes 20 to 30 minutes and costs $20 to $40 for the battery itself.
  • iPhone 14 and older models require opening the phone with a pentalobe screwdriver and disconnecting internal cables, which can damage the display if you slip, so professional replacement is safer.
  • Apple replaces any iPhone battery for $50 to $80 at an Apple Store or through mail-in service, and the repair is free if your phone is under warranty and battery health is below 80 percent.
  • You can check your battery health in Settings > Battery > Battery Health & Charging to see the current capacity percentage before deciding whether to replace it.
  • Third-party repair shops often charge less than Apple but may void your warranty, so compare prices and reviews in your area before choosing.

How to check your iPhone battery health before replacing it

Open Settings, tap Battery, then tap Battery Health & Charging. You will see a number labeled "Maximum Capacity"—this is the percentage of the battery's original charge your phone can now hold. A new iPhone battery is at 100 percent. At 80 percent, the battery is considered degraded. At 50 percent or lower, you will notice the phone drains quickly and may shut down unexpectedly even when the battery percentage shows 20 or 30 percent.

If you are under warranty or have AppleCare+, Apple will replace the battery at no cost if the maximum capacity is below 80 percent. If you are out of warranty, you pay the standard replacement fee. Many people replace their battery when it drops to 70 to 75 percent, before the phone becomes unreliable, rather than waiting until it fails.

Replacing an iPhone 15 or later battery yourself

iPhone 15, 15 Plus, 15 Pro, and 15 Pro Max all have removable batteries. You will need a replacement battery (sold by Apple or third-party makers like iFixit), a heat gun or hair dryer, a plastic pry tool or old credit card, and tweezers. Do not use a metal screwdriver or knife—you will puncture the battery or scratch the phone's interior.

Heat the back of the phone with a heat gun on low setting or a hair dryer for 2 to 3 minutes until the adhesive softens. Insert the plastic tool at the bottom edge and gently pry upward to create a gap. Slide the tool along the edge to loosen the battery, then use tweezers to pull the battery tab and lift it out. Insert the new battery, press it down firmly, and let the adhesive set for a few minutes before powering on. Apple's support page has a step-by-step video for your specific model.

The battery itself costs $20 to $40 depending on the model. If you damage the display or internal components during removal, repair costs will be much higher, so take your time and do not force anything.

Replacing an iPhone 14 or older battery yourself

Older iPhones require you to remove the display first, which is glued to the frame. You need a pentalobe screwdriver (size P2), a heat gun or hair dryer, a suction cup, a plastic pry tool, tweezers, and a replacement battery. The display is the most expensive part to replace if you crack it, so this repair carries real risk.

Heat the edges of the display for 2 to 3 minutes, use the suction cup to create a gap at the bottom, and slide the plastic tool around the edge to break the adhesive seal. Once the display is loose, carefully lift it and prop it open—do not fully remove it yet, because the display cable is still connected. Disconnect the battery connector first (a small plug on the logic board), then disconnect the display cable. Now you can fully remove the display and set it aside.

Remove the pentalobe screws holding the battery connector bracket, then peel back the battery adhesive tabs and lift out the old battery. Insert the new battery, reconnect the battery connector, reconnect the display cable, and press the display back down. Let the adhesive cure for 24 hours before using the phone heavily. iFixit and Apple both publish detailed guides with photos for each model.

Having Apple or an authorized shop replace your battery

Visit an Apple Store, schedule a mail-in repair through apple.com, or find an authorized Apple repair shop in your area. At an Apple Store, battery replacement usually takes 3 to 5 business days because they order batteries in batches. Mail-in service takes 5 to 7 business days plus shipping time. You will need to back up your phone before dropping it off, though Apple will not erase it during a battery replacement.

The cost is $50 to $80 depending on your iPhone model—check apple.com/support/repair for your exact model. If your phone is under warranty or AppleCare+, the replacement is free if the battery health is below 80 percent. If you are out of warranty and the battery is straightforward old but still above 80 percent capacity, you pay the full fee.

Authorized third-party shops (look for the "Apple Authorized Service Provider" badge) often charge $10 to $20 less than Apple, but confirm they use genuine Apple batteries and offer a warranty on the repair. Some third-party shops use lower-cost aftermarket batteries, which may not last as long or hold a charge as reliably.

What to expect after battery replacement

After replacement, your phone's battery health will show 100 percent in Settings > Battery > Battery Health & Charging. The new battery will charge and drain normally, and you should not notice any change in how the phone performs. If you replaced the battery yourself and the phone does not power on, or if the display does not work, you may have disconnected a cable incorrectly—do not force anything, and take the phone to a repair shop to diagnose the problem.

A new battery typically lasts 3 to 5 years before capacity drops noticeably, depending on how often you charge it and whether you keep the phone in hot conditions. Charging the phone to 100 percent every day and leaving it plugged in overnight will degrade the battery faster than charging it to 80 percent and unplugging it. You can set a charging limit in Settings > Battery > Battery Health & Charging on newer iPhones to slow degradation.

When to call a professional instead of doing it yourself

If your iPhone is an older model (iPhone 14 or earlier), the display is cracked, or you have never opened a phone before, take it to Apple or an authorized shop. The cost of a professional replacement ($50 to $80) is much less than the cost of repairing a broken display ($200 to $400) if you slip with a screwdriver.

If your phone is under warranty or AppleCare+, opening it yourself will void the coverage. Apple can tell if a phone has been opened by checking for tamper indicators inside, so if something goes wrong after a DIY repair, Apple will not cover it. If you are not certain you can complete the repair without damage, the warranty protection is worth the service fee.

Frequently Asked Questions

Can I replace my iPhone battery without going to Apple?

Yes, if you own an iPhone 15 or later, you can replace the battery yourself with a heat gun, plastic tool, and a replacement battery from Apple or a third-party maker. For iPhone 14 and older, you can do it yourself but it requires opening the phone with a pentalobe screwdriver and disconnecting cables, which risks damage. Third-party repair shops are also an option and often cost less than Apple.

How long does it take Apple to replace a battery?

At an Apple Store, battery replacement usually takes 3 to 5 business days. Mail-in service takes 5 to 7 business days plus shipping time. Some stores may have batteries in stock and complete the repair the same day, so call ahead to ask.

Will replacing the battery erase my data?

No, battery replacement does not erase your phone or require a backup. Apple does not touch the storage during the repair. You should back up your phone before any repair just in case, but it is not necessary for a battery replacement.

Is it cheaper to replace the battery myself or use Apple?

For iPhone 15 and later, DIY replacement costs $20 to $40 for the battery. Apple charges $50 to $80. For older models, DIY requires more tools and carries a higher risk of damage, so the Apple fee is usually worth it unless you are experienced with phone repairs.

What if my phone is still under warranty?

If your battery health is below 80 percent and your phone is under warranty or AppleCare+, Apple will replace the battery at no cost. Check your coverage at apple.com/support by entering your serial number. Opening the phone yourself will void the warranty.
