Yes, you can replace an iPhone battery, but the method depends on your model and whether you do it yourself or use a service

iPhone batteries wear out over time—typically after 500 full charge cycles, your battery holds less charge than it did new. Apple rates their batteries to retain 80 percent of their capacity after that point. You have three real options: replace the battery yourself if you have the right tools and your model supports it, take it to Apple, or use an independent repair shop. The easiest and safest route for most people is Apple or an authorized repair center, but it costs money and takes time. Self-repair is possible on newer models but requires specific tools and patience.

The cost ranges from free (if you are still under warranty and your battery is below 80 percent capacity) to $69–$99 at Apple, or $40–$80 at independent shops. The time commitment ranges from 20 minutes if you do it yourself on an iPhone 15 or newer, to one to two hours at an Apple Store, to five to seven business days if you mail your phone in.

Key Takeaways

  • Apple's official battery replacement costs between $69 and $99 depending on your iPhone model, and takes one to two hours at most locations or one to two weeks by mail.
  • Newer iPhones (iPhone 15 and later) have a removable battery design that makes self-replacement possible with basic tools, while older models require heating and prying that risks damage.
  • Independent repair shops often charge less than Apple but may void your AppleCare+ warranty, so check your coverage before choosing.
  • You can check your battery health in Settings > Battery and Device Care > Battery Health to see if replacement is necessary now or can wait.
  • Mail-in repair through Apple takes longer but works if no local service center is nearby.

How to check if your battery actually needs replacement

Before you spend money or time, open Settings, then tap Battery (or Battery and Device Care on newer models), then Battery Health. You will see a percentage—this is your battery's maximum capacity compared to when it was new. If it is above 80 percent, your battery is still within normal wear. If it is below 80 percent and you notice your phone shuts down unexpectedly or drains quickly even when you are not using it heavily, replacement makes sense.

Apple also shows you whether your battery is in "Peak Performance Condition" or if it has been throttled. Throttling means Apple has slowed down your processor to prevent unexpected shutdowns—a sign that replacement would improve real-world speed. If your battery is at 50 percent capacity or lower, you will almost certainly notice a difference after replacement. Check this number before you book an appointment, because it tells you whether the cost is worth it right now or whether you can wait a few more months.

Getting your battery replaced at Apple

Visit apple.com/support or call Apple Support to find a nearby Apple Store or Apple Authorized Service Provider. You can book an appointment online or by phone. Bring your iPhone and your Apple ID password—Apple will ask for it to back up your data and disable Find My iPhone before the repair.

The repair itself takes one to two hours at most Apple Stores if you wait, or you can drop it off and pick it up the next day. Apple replaces the entire battery unit and tests it before handing your phone back. Your warranty covers battery replacement if your battery capacity has dropped below 80 percent within one year of purchase. After one year, the cost is $69 for iPhone 15 and 15 Plus, $79 for iPhone 15 Pro and Pro Max, and varies for older models—ask when you book. If you mail your phone to Apple instead, the process takes five to seven business days plus shipping time. You can start a mail-in repair through apple.com/support by selecting your device and choosing "Battery Service."

Self-replacement on iPhone 15 and newer models

Apple introduced a removable battery design starting with iPhone 15, which means you can replace the battery yourself without heating or prying. You will need a pentalobe screwdriver (the five-pointed star shape Apple uses), a plastic spudger or opening tool, and tweezers. These tools are sold together in iPhone repair kits for $15 to $30 on Amazon or at electronics retailers. Replacement batteries for iPhone 15 cost $40 to $60 from Apple or third-party sellers.

Power off your phone completely. Remove the two pentalobe screws at the bottom of the phone near the charging port. Use the plastic spudger to gently pry up the bottom edge—start at a corner and work slowly around the edge. The screen will separate from the body. Disconnect the battery connector (a small plug near the top of the battery) by gently pulling the tab. Remove the battery pull-tab and slide the battery out. Insert the new battery, reconnect the battery plug, and reassemble the phone by pressing the screen back down until it clicks. The whole process takes 20 to 40 minutes if you move carefully. If you rush or explore too much force, you risk cracking the screen or damaging the battery connector, so take your time.

Why self-replacement is difficult on older iPhone models

iPhones before the iPhone 15 use adhesive to hold the battery in place, not a straightforward connector. To remove the battery, you must heat the phone to soften the adhesive, then carefully pry the battery out with a spudger without puncturing it or damaging nearby components. A punctured lithium battery can catch fire, and the adhesive is strong enough that you risk cracking the screen or logic board if you explore too much force.

If you still want to try, you will need a heat gun or hair dryer, a plastic spudger, tweezers, and iFixit's battery removal strips (thin adhesive tabs that help lift the battery safely). Even with the right tools, the risk of damage is real. Most people find it worth paying Apple or a repair shop to avoid that risk, especially on phones that are still under warranty or AppleCare+ coverage.

Using an independent repair shop

Independent repair shops like uBreakiFix, Best Buy's Geek Squad, or local phone repair stores often charge $40 to $80 for battery replacement, which is less than Apple's price. Many offer same-day or next-day service. Before you go, ask whether they use original Apple batteries or third-party batteries—original batteries are more reliable and less likely to cause problems down the road.

One trade-off: using an independent shop may void your AppleCare+ warranty if you have one, depending on the terms. Check your coverage before you decide. If your phone is still under the standard one-year warranty and your battery is below 80 percent capacity, Apple's warranty covers the replacement at no cost, so there is no reason to go elsewhere. After the warranty expires, the cost difference between Apple and an independent shop becomes the main factor in your decision.

What to expect after battery replacement

A new battery will show 100 percent capacity in Settings > Battery Health. Your phone should hold a charge noticeably longer and should not shut down unexpectedly. If your phone was throttled before replacement, it will run at full speed again. The new battery will start wearing down when ready—this is normal and expected. You will not need another replacement for at least two to three years if you use your phone normally.

If you replaced the battery yourself, your phone should work exactly as it did before, with no difference in performance or features. If you used Apple or an authorized service, your data and settings remain unchanged because Apple backs everything up before the repair. Either way, your phone will feel noticeably faster and more responsive if it was throttled, and the battery drain will slow down significantly.

Frequently Asked Questions

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

Apple rates their batteries to retain 80 percent capacity after 500 full charge cycles, which is roughly one to two years of normal use. Some people reach that point faster if they charge their phone multiple times daily or use power-hungry apps constantly. Others go three years or more before needing replacement.

Will replacing my battery fix a phone that shuts down randomly?

If your battery health is below 80 percent and your phone shuts down even when the battery percentage shows 20 or 30 percent remaining, replacement will almost certainly fix it. If your battery health is still above 80 percent, the shutdowns may be caused by something else—contact Apple Support to troubleshoot before paying for a replacement.

Can I replace my iPhone battery at a non-Apple store without losing my warranty?

If your phone is still under the one-year limited warranty and your battery capacity is below 80 percent, Apple covers the replacement at no cost. Using an independent shop may void AppleCare+ coverage if you have it, so check your plan first. After the one-year warranty expires, using any repair shop will not affect your coverage because the standard warranty is already gone.

Is it safe to replace an iPhone battery myself?

On iPhone 15 and newer, self-replacement is safe if you follow the steps carefully and use the right tools. On older models, the adhesive and risk of puncturing the battery make self-replacement risky for most people. If you are not comfortable with small, precise work, paying a professional is worth the cost to avoid damage.

What should I do with my old battery after replacement?

Do not throw it in the trash—lithium batteries are recyclable and contain materials that can be recovered. Apple takes old batteries back for free at any Apple Store. Most independent repair shops and Best Buy also accept batteries for recycling. Some retailers like Best Buy have battery recycling kiosks near the entrance.
