You cannot remove an iPhone battery yourself without damaging the phone

Unlike older phones, iPhones are sealed devices. The battery is glued to the inside of the case, and removing it requires heating the adhesive, prying open the screen, disconnecting internal cables, and using specialized tools. Attempting this at home will almost certainly crack the screen, damage the logic board, or break the battery itself—which can be a fire hazard if punctured.

If your battery is failing, your options are to have Apple or an authorized repair shop remove and replace it, or to use iOS settings to manage the battery's performance while you decide what to do next.

Key Takeaways

  • iPhone batteries are permanently glued inside the case and require heating tools and specialized equipment to remove safely.
  • Apple and authorized repair providers can replace your battery in one to three hours, and the cost depends on your iPhone model and warranty status.
  • If your battery is degraded but your phone still works, you can extend its life by enabling Low Power Mode and checking battery health in Settings.
  • Third-party repair shops can replace batteries at lower cost than Apple, but may void your warranty or use non-original parts.

Why the battery is sealed inside

Apple designs iPhones to be waterproof and dustproof. The sealed case protects the internal components from moisture, which is why the battery cannot be accessed from the outside. The battery is adhered to the aluminum frame with a strong adhesive, and removing it means disassembling the entire phone.

This design also makes the phone thinner and lighter than it would be if the battery were user-removable. The trade-off is that battery replacement requires professional tools and training.

Getting a battery replaced at Apple

Apple offers battery replacement through the Apple Store or by mail. You can start by visiting apple.com/support, selecting your device, and choosing "Battery and Charging" from the support topics. This will show you the current battery health status and let you book a repair appointment.

At an Apple Store, a technician will run a diagnostic to confirm the battery is the problem, then replace it while you wait—usually within one to three hours. The cost varies by iPhone model. If your phone is still under the one-year limited warranty or covered by AppleCare+, the replacement may be covered at no charge. If not, you will pay a flat fee that ranges depending on your model.

If you cannot visit a store, Apple also offers mail-in repair. You can request a prepaid shipping label through the support page, send your phone to Apple, and they will replace the battery and return it to you within five to seven business days.

Using an authorized repair provider

Authorized Apple repair shops (often called AASP locations) can replace iPhone batteries using genuine Apple parts. These shops are certified by Apple and follow the same repair standards as the Apple Store. You can find one near you by visiting apple.com/support, clicking "Find Locations," and filtering for "Authorized Service Providers."

Authorized shops often have shorter wait times than Apple Stores and may offer same-day service. The battery replacement cost is the same as at Apple, and your warranty coverage remains unchanged.

Third-party repair shops and the risks

Independent repair shops can replace an iPhone battery at a lower cost than Apple—sometimes 30 to 50 percent less. However, there are real risks. Third-party shops may use non-original batteries that do not hold a charge as long or may fail sooner. They may also damage other components during disassembly, such as the screen, camera, or logic board.

If you use a third-party shop, your AppleCare+ coverage will end, and Apple will not service the phone under warranty afterward. Some third-party batteries also lack proper safety certification, which increases the risk of overheating or swelling. If you choose this route, research the shop's reviews and ask whether they use original or aftermarket batteries before committing.

Checking your battery health before you replace it

Before paying for a replacement, check whether your battery is actually the problem. Go to Settings > Battery > Battery Health & Charging on your iPhone. This screen shows your battery's maximum capacity as a percentage—for example, "80% maximum capacity."

A battery at 80 percent or higher is considered normal. Between 75 and 80 percent is still acceptable for most users. Below 75 percent, you may notice the phone shuts down unexpectedly under load or drains faster than it used to. If your battery is above 75 percent and your phone is still working well, you may not need a replacement yet.

The Battery Health screen also shows whether the battery is in "Peak Performance Condition" or whether iOS has applied performance management to prevent unexpected shutdowns. If performance management is active, your phone may feel slower than usual—this is a sign the battery is degraded.

Extending battery life while you decide

If your battery is degraded but you are not ready to replace it, you can reduce the strain on it. Enable Low Power Mode by going to Settings > Battery > Low Power Mode and toggling it on. This reduces background activity, limits performance, and can extend your battery's life by several hours per charge.

You can also reduce battery wear by keeping your phone cooler (avoid direct sunlight and hot environments), avoiding deep discharges (do not let the battery drop to zero regularly), and disabling features you do not use, such as location services, Bluetooth, and background app refresh. These steps will not restore a degraded battery, but they will make it last longer while you arrange a replacement.

Frequently Asked Questions

Can I replace my iPhone battery myself?

You can, but it is not recommended. Removing the battery requires heating the phone to soften the adhesive, prying open the screen (which often cracks), disconnecting delicate ribbon cables, and using specialized tools. Most people damage the phone in the process. If you do puncture the battery, it can catch fire or explode.

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

Apple designs iPhone batteries to retain 80 percent of their capacity after 500 full charge cycles. In real use, this typically means two to three 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.

What is the cost of a battery replacement?

The cost varies by iPhone model and ranges from about $50 to $100 at Apple or authorized shops. If your phone is under warranty or covered by AppleCare+, the replacement may be covered at no charge. Third-party shops often charge $30 to $60, but use non-original parts and may void your warranty.

Will replacing the battery erase my data?

No. A battery replacement does not affect your data, photos, apps, or settings. The technician only removes and replaces the battery itself. Your phone will have the same content and configuration when you get it back.

Can I use my phone while the battery is being replaced?

No. The phone must be powered off and disassembled to access the battery. At an Apple Store or authorized shop, the replacement usually takes one to three hours. If you use mail-in repair, you will be without your phone for five to seven business days.
