You cannot safely remove an iPhone battery yourself
iPhones are sealed devices. Apple does not design them for you to open, and the battery is glued to the inside of the case. Prying it out risks damaging the phone permanently, breaking the screen, puncturing the battery (which can cause a fire), or cutting yourself on sharp internal parts. Even small mistakes during opening can destroy components worth more than the repair itself.
If your battery is failing, draining too fast, or swelling, the safe path is to have Apple or an authorized repair shop remove and replace it. This takes about an hour and costs less than you might expect—often $50 to $100 depending on your iPhone model.
Key Takeaways
- iPhone batteries are permanently glued inside a sealed case and cannot be removed without professional tools and training.
- Attempting to open your iPhone yourself can damage the screen, break internal components, or cause the battery to catch fire.
- Apple Stores and authorized repair shops have the right equipment to remove batteries safely and replace them in under an hour.
- Battery replacement costs between $50 and $100 at most Apple locations, depending on your iPhone model and whether you have warranty coverage.
- If your battery is swelling, bulging, or leaking, stop using the phone and take it to a repair shop when ready rather than trying to open it.
Why iPhones are sealed and what that means for repairs
Apple sealed iPhones starting with the iPhone 6s in 2015. The battery is adhered to the internal frame with strong adhesive, and the case itself is fused together. This design makes the phone thinner and more water-resistant, but it also means battery replacement requires disassembly by someone trained to do it without destroying the device.
Opening an iPhone without the right tools—specialized screwdrivers, pry tools, heat guns, and adhesive remover—almost always results in cracked screens or damaged logic boards. The parts inside are tightly packed, and one slip can sever a ribbon cable that connects the screen or camera. Replacing that cable costs more than a battery replacement would have.
What happens when you take your iPhone to Apple for battery replacement
Apple Stores and authorized service providers have the equipment and training to safely open your iPhone. They use heat to soften the adhesive, specialized pry tools to separate the case without cracking it, and the correct screwdrivers for internal fasteners. The whole process takes 30 minutes to an hour.
You will need to back up your data before you go, though the technician will not erase your phone during a battery replacement. Bring your iPhone and a form of ID. If you have AppleCare+ coverage, battery replacement is usually free if the battery health has fallen below 80 percent. Without coverage, the cost is typically $69 for an iPhone 15, $79 for an iPhone 14, and $89 for older models, though prices vary slightly by location.
How to find an Apple Store or authorized repair shop near you
Visit apple.com/repair and enter your zip code. Apple will show you nearby Apple Stores and authorized service providers, their hours, and whether they have same-day appointments available. You can book directly from that page or call the location to schedule.
If no Apple Store is nearby, authorized repair shops—often found at Best Buy, carrier stores, or independent repair centers—can also replace your battery. Ask whether they use genuine Apple parts and whether the repair comes with a warranty. Some third-party shops use lower-cost batteries that may not last as long or hold a charge as well as Apple's original batteries.
Signs your battery needs replacement soon
Your iPhone will tell you when the battery is failing. Go to Settings > Battery > Battery Health & Charging. If the maximum capacity shows below 80 percent, your battery is degrading and will continue to lose capacity. If it shows 50 percent or lower, replacement is urgent—the phone may shut down unexpectedly even when the battery percentage reads 20 or 30 percent.
Other signs include the phone draining from 50 percent to dead in an hour or two, the phone shutting down suddenly and then turning back on when you plug it in, or the back of the phone feeling warm or slightly swollen. A swollen battery is a safety hazard and should be taken to a repair shop when ready. Do not attempt to open the phone or charge it further.
What to do if your battery is swelling or leaking
A swollen battery pushes against the screen and case from the inside, and it can rupture. If you notice the back of your phone bulging, the screen lifting away from the frame, or liquid leaking from the seams, stop using the phone and take it to a repair shop the same day. Do not charge it, do not try to open it, and do not leave it in a hot car.
Tell the repair shop that the battery is swollen when you arrive. They will prioritize it and take precautions to prevent the battery from rupturing during removal. In rare cases, a swollen battery can catch fire if punctured, so professional handling is essential.
Third-party repair shops and mail-in options
If you cannot reach an Apple Store, independent repair shops and mail-in services like iFixit or uBreakiFix can replace your battery. Costs are often similar to Apple's prices, sometimes lower. Ask whether they use genuine Apple batteries or third-party replacements, and whether the repair includes a warranty.
Mail-in services will send you a prepaid shipping label, you mail your phone to them, and they return it within 5 to 10 business days. This is slower than an in-store visit but works if no local shops are available. Read reviews before choosing a mail-in service, and confirm their warranty policy in case something goes wrong during the repair.
Frequently Asked Questions
Can I replace my iPhone battery with a non-Apple battery?
Yes, but Apple batteries are designed specifically for your iPhone model and tend to last longer. Third-party batteries are cheaper upfront but may not hold a charge as well after a year. If you choose a third-party battery, ask the repair shop for a warranty—usually one year—in case it fails early.
How long does a new iPhone battery last?
A new battery should hold 80 percent of its capacity for about two to three years under normal use. After that, it will begin to degrade. Most people replace their battery once every three to four years, though heavy users may need replacement sooner.
Will replacing my battery erase my photos and data?
No. Battery replacement does not touch your data. Your photos, messages, and settings will remain exactly as they are. You do not need to back up before going to the repair shop, though it is always a good idea to have a recent backup for any reason.
What if my iPhone is still under warranty?
If your iPhone is less than one year old and the battery capacity has fallen below 80 percent due to a manufacturing defect, Apple will replace it free. If you have AppleCare+, battery replacement is free if capacity is below 80 percent. Otherwise, you pay the standard fee. Bring your receipt or proof of purchase to confirm your warranty status.
Can I use my iPhone while I wait for battery replacement?
Yes, but avoid heavy use—gaming, video streaming, or charging to 100 percent repeatedly. A failing battery can overheat during heavy use, which speeds up degradation and can damage other components. Use the phone normally for calls, texts, and light browsing until you can get it repaired.
