The battery is inside your iPhone, sealed behind the back glass or aluminum frame
You cannot open an iPhone yourself to reach the battery the way you might with an older Android phone. Apple glues the battery inside the device, and removing it requires specialized tools and training. The battery sits behind the back panel of your phone — you will not find a removable battery door or a slot on the side.
If your battery is failing, you have two realistic options: take your iPhone to Apple or an authorized repair shop, or contact Apple Support to arrange a mail-in repair. Attempting to open the phone yourself will damage it and void any remaining warranty.
Key Takeaways
- The battery is sealed inside your iPhone behind the back glass or aluminum casing and cannot be removed by the user.
- If your battery drains too quickly or will not hold a charge, Apple offers battery replacement through Apple Stores, authorized repair shops, and mail-in service.
- Battery replacement costs vary by iPhone model but typically range from $50 to $100 when done through Apple.
- You can check your battery health in Settings > Battery > Battery Health & Charging to see if replacement is needed.
How to check if your battery needs replacement
Before you arrange a repair, look at your battery's actual health. Open Settings, tap Battery, then tap Battery Health & Charging. You will see a percentage labeled "Maximum Capacity" — this tells you how much charge your battery can hold compared to when it was new.
If the percentage is 80% or higher, your battery is still in reasonable condition. If it has dropped below 80%, Apple considers the battery degraded. At 50% capacity or lower, you will notice the phone draining much faster than normal, and Apple will definitely recommend replacement.
You will also see a "Condition" line that says either "Normal" or "Service Recommended." If it says "Service Recommended," your battery should be replaced soon.
Getting your battery replaced at an Apple Store
The fastest way to replace your battery is to visit an Apple Store in person. Go to apple.com/retail, find the store nearest you, and use the "Genius Bar" booking system to schedule an appointment. Tell them you need battery service. Bring your iPhone and your Apple ID password.
The repair usually takes 1 to 3 hours if the store has the part in stock. If they do not, they may order it and you will pick up the phone later that day or the next day. You will pay at the time of service — the cost depends on your iPhone model, but Apple publishes the price before you book.
If your iPhone is still under warranty or covered by AppleCare+, the battery replacement may be free or discounted. The technician will check your coverage when you arrive.
Using an authorized repair shop
If there is no Apple Store near you, find an authorized Apple repair shop through apple.com/repair. These are independent businesses that Apple has trained and certified to do repairs using genuine parts. The process is the same as an Apple Store: book an appointment, bring your phone, and wait for the repair.
Authorized shops charge the same prices as Apple Stores for battery replacement. The repair time is usually similar, though it can vary depending on how busy the shop is.
Mailing your iPhone for battery service
If you cannot visit a store or authorized shop, you can send your iPhone to Apple for repair. Call Apple Support at 1-800-MY-APPLE or start a repair request at support.apple.com. Apple will send you a prepaid shipping box, you pack your phone inside, and Apple handles the repair at their facility.
Mail-in repair typically takes 5 to 7 business days from the time Apple receives your phone. You will be without your device during this time, so this option works best if you have a backup phone or can wait.
Apple will contact you if the repair costs more than expected or if they find other damage. You will pay for the service before they ship the phone back to you.
What happens if you try to open the iPhone yourself
Opening an iPhone requires heating the back glass to soften the adhesive, then prying it off with a suction cup and specialized tools. Even small mistakes can crack the glass, damage the display, or break the logic board. If you damage the phone while trying to replace the battery yourself, Apple will not repair it under warranty, and the repair cost will be much higher than a straightforward battery replacement.
Third-party repair shops that are not Apple-authorized may offer cheaper battery replacement, but they often use non-genuine parts that do not perform as well and may damage your phone in the process. If something goes wrong, you have no recourse.
Battery replacement costs and what affects the price
Apple charges different amounts depending on your iPhone model. Older models like the iPhone 11 or iPhone XS typically cost less to replace than newer models like the iPhone 15. The price also depends on whether your phone is under warranty or covered by AppleCare+.
If your iPhone is out of warranty and you do not have AppleCare+, you will pay the full service fee. If your battery is failing due to a manufacturing defect and your phone is still under the one-year limited warranty, the replacement is free. AppleCare+ covers battery replacement at no cost if the battery capacity has fallen below 80%.
Contact Apple Support or visit your local Apple Store to find out the exact price for your model before you book the repair.
Frequently Asked Questions
Can I replace the battery myself with a kit from online?
You can buy battery replacement kits online, but they require heating tools, adhesive removal, and reassembly skills that most people do not have. The risk of breaking your screen or damaging internal components is high. A professional replacement through Apple or an authorized shop is safer and often not much more expensive when you factor in the cost of tools and the risk of ruining your phone.
How long does an iPhone battery last before it needs replacement?
Apple designs iPhone batteries to retain 80% of their capacity after 500 full charge cycles. In real use, this usually means 2 to 3 years before the battery noticeably degrades. The exact timeline depends on how often you charge, the temperatures you expose the phone to, and your usage patterns.
Will replacing the battery fix my phone if it keeps shutting down?
If your phone shuts down suddenly even when the battery shows charge remaining, a failing battery is often the cause. Check Battery Health in Settings first — if the capacity is very low, replacement should fix the problem. If the capacity is still high, the shutdown may be caused by something else, and a technician should diagnose it before you pay for a battery replacement.
What should I do with my old battery after it is replaced?
Do not throw the old battery in the trash — lithium batteries can catch fire in landfills. Apple and authorized repair shops will recycle the old battery for you at no cost. If you mail in your phone, Apple handles the recycling. If you visit a store, ask the technician to recycle it.
Can I use my iPhone while it is being repaired?
At an Apple Store or authorized shop, the repair usually takes a few hours, so you will be without your phone during that time. For mail-in service, you will not have access to your phone for 5 to 7 days. If you need your phone during the repair, ask the store if they have a loaner device available, though availability varies by location.
