You can replace your iPhone 13 battery yourself or have Apple do it

Apple will replace your iPhone 13 battery for a flat fee of $69 if your phone is out of warranty, or free if you have AppleCare+. The process takes three to five business days at an Apple Store or Apple Authorized Service Provider. If you want to do it yourself, you will need a pentalobe screwdriver, a heat gun or hair dryer, adhesive strips, and a battery replacement kit — the total cost runs $20 to $40, but the work requires patience and carries the risk of damaging your screen or logic board if you slip.

Your choice depends on whether you value speed and a warranty over cost and control. Apple's route is safer for your phone but slower and more expensive. The DIY route is cheaper and faster but demands a steady hand and careful attention to several fiddly steps.

Key Takeaways

  • Apple charges $69 for an out-of-warranty battery replacement and completes the work in three to five business days at an Apple Store or authorized service provider.
  • A DIY replacement costs $20 to $40 in parts and takes one to two hours, but requires a pentalobe screwdriver, heat gun, and careful handling of adhesive strips and delicate ribbon cables.
  • The iPhone 13 battery is glued to the phone's interior, so you must heat the adhesive first or risk cracking the screen during removal.
  • Apple's battery replacement comes with a 90-day warranty on the battery itself, while DIY replacements carry no warranty if something goes wrong.

What you need to replace the battery yourself

Start with a pentalobe screwdriver — the five-pointed tool Apple uses on the iPhone 13's bottom screws. A standard Phillips head will not work. You can buy one for $5 to $10 at electronics retailers or online.

You will also need a heat gun or hair dryer to soften the adhesive holding the battery in place. A hair dryer on high heat works, though a heat gun gives you more control. Do not use an oven or microwave — the risk of fire or damage is too high.

A battery replacement kit for the iPhone 13 costs $15 to $30 and includes the battery itself, new adhesive strips, and usually a plastic pry tool and tweezers. Buy from a reputable electronics supplier; cheap kits sometimes include batteries with lower capacity than Apple's original.

You will also need a clean, well-lit workspace, a small container to hold the five screws you will remove, and a soft cloth to wipe away old adhesive residue.

Step-by-step: removing the screen and battery

Power off your iPhone 13 completely. Use the pentalobe screwdriver to remove the two screws at the bottom of the phone on either side of the charging port — these hold the screen in place.

Heat the edges of the screen with your heat gun or hair dryer for 30 to 60 seconds. The goal is to warm the adhesive, not to make the phone too hot to touch. Use the plastic pry tool to gently lift one corner of the screen — start at the bottom and work your way around. The screen is connected to the phone by ribbon cables at the top, so do not pull it all the way off yet. Lift it slowly and prop it open at an angle so you can access the battery underneath.

Locate the battery connector — a small rectangular plug near the top of the phone's interior. Disconnect it by gently prying the connector away from its socket with the plastic tool. This step disables the battery and prevents accidental short circuits while you work.

Heat the battery area for another 30 to 60 seconds. The battery is glued down with strong adhesive, so take your time. Use the plastic tool or tweezers to peel away the battery slowly from one corner. If it resists, heat it again rather than forcing it — forcing can crack the screen or damage the logic board underneath.

Installing the new battery and reassembling

Clean any old adhesive residue from the battery compartment with a soft cloth. Do not use solvents or water — they can damage the phone's interior components.

Remove the backing from the new adhesive strips that came in your kit and press them into the battery compartment in the same pattern as the old ones. If your kit did not include adhesive strips, you can use thin double-sided tape, though Apple's adhesive is stronger.

Slide the new battery into place and press it down firmly for a few seconds so the adhesive sets. Reconnect the battery connector by pressing it back into its socket until you hear or feel a click.

Carefully lower the screen back down and press it into place around all edges. The adhesive on the screen should hold it, but if it feels loose, you can add a thin line of adhesive around the perimeter before closing it. Replace the two pentalobe screws at the bottom of the phone and tighten them by hand — do not over-tighten, as this can strip the threads.

Power on your phone and check that the battery percentage appears in the status bar. Go to Settings > Battery > Battery Health & Charging to verify that the new battery is recognized. The health percentage may show as unknown for the first few charge cycles.

When to choose Apple's service instead

Apple's battery replacement makes sense if you are uncomfortable opening your phone, if you want a warranty on the work, or if you are in a hurry and can visit an Apple Store or authorized service provider nearby. The $69 fee is reasonable for the labor and the 90-day warranty on the battery itself.

You can schedule a battery replacement appointment through Apple's website or by calling your local Apple Store. Bring your phone and a form of identification. If your phone has a cracked screen, Apple may ask you to repair that first, since the screen must be opened to access the battery.

If you have AppleCare+, the replacement is free. Check your coverage by going to Settings > General > About and scrolling to the bottom, or by visiting apple.com and signing in with your Apple ID.

Signs your iPhone 13 battery needs replacement

Your battery is degrading if your phone shuts down unexpectedly when the battery percentage is still above 20 percent, if it drains noticeably faster than it did six months ago, or if the phone feels warm during normal use. You can also check the battery's health directly: go to Settings > Battery > Battery Health & Charging and look at the Maximum Capacity percentage. If it is below 80 percent, the battery is aging and a replacement will improve performance.

The iPhone 13 battery is rated for 1,000 full charge cycles before it degrades to 80 percent capacity. A full charge cycle means draining the battery from 100 percent to zero and charging it back to 100 — not necessarily in one day. Most people reach this point after two to three years of normal use.

Common mistakes to avoid

Do not skip disconnecting the battery connector before you start removing the old battery. Even though the phone is powered off, the battery still holds a charge, and touching the wrong component while it is connected can cause a short circuit.

Do not use excessive heat. If you overheat the phone, you risk damaging the screen, the logic board, or the battery itself. If the adhesive is not softening after 60 seconds of heat, wait a moment and try again rather than turning up the heat.

Do not reuse the old adhesive strips. They lose their stickiness once removed and will not hold the new battery securely. Always use fresh adhesive from your replacement kit.

Do not force the screen or battery. If something is stuck, heat it again. Forcing can crack the screen, which is expensive to replace, or damage ribbon cables, which can disable parts of your phone permanently.

Frequently Asked Questions

How long does a DIY battery replacement take?

Most people complete the job in one to two hours on their first attempt. If you are experienced with phone repairs, you can do it in 30 to 45 minutes. The longest part is usually waiting for the adhesive to soften and carefully peeling the old battery away.

Will replacing the battery myself void my warranty?

Yes. Opening your iPhone 13 voids any remaining manufacturer warranty. If something breaks during the replacement or shortly after, Apple will not cover it under warranty. AppleCare+ coverage may also be affected — contact Apple before you open the phone if you want to confirm your coverage status.

Can I use a hair dryer instead of a heat gun?

Yes. A hair dryer on high heat works, though it takes longer to soften the adhesive and gives you less precise control over the temperature. Keep the dryer moving so you do not overheat one spot. A heat gun is faster and safer if you have access to one.

What should I do if I crack the screen while removing the battery?

Stop when ready and do not continue. A cracked screen can cut your fingers and the cracks can spread as you work. Take the phone to Apple or an authorized service provider for screen replacement. The screen replacement fee is separate from the battery replacement fee.

Is the iPhone 13 battery the same as the iPhone 13 Pro?

No. The iPhone 13 and iPhone 13 mini use the same battery, but the iPhone 13 Pro and iPhone 13 Pro Max use different, larger batteries. Make sure your replacement kit is labeled for your specific model before you start the repair.
