About genuine iPhone batteries

All rechargeable batteries are consumables and have a limited lifespan. Eventually their capacity and performance decline and they need to be replaced. iPhone uses built-in, high-quality lithium-ion batteries. They're designed, tested and manufactured rigorously to meet Apple’s quality and performance standards. These genuine Apple batteries have also been certified for safety.

Importance of servicing by trained technicians using genuine Apple batteries

For most customers, visiting a professional repair provider with certified technicians who use genuine Apple parts is the safest and most reliable way to get a repair. These providers include Apple and Apple Authorised Service Providers, and Independent Repair Providers, who have access to genuine Apple parts.*

Lithium-ion batteries are sensitive components and should be serviced with care. To avoid damage that could cause overheating, fire or injury, only trained technicians should replace the battery in your iPhone. Repairs performed by untrained individuals using non-genuine parts may affect the safety of the device or cause the device to function incorrectly.

Depending on your location, you can get your iPhone battery replaced – in or out of warranty – by visiting an Apple Store or Apple Authorised Service Provider, or by sending your iPhone to an Apple Repair Centre. Independent Repair Providers* also offer genuine parts by trained technicians for out-of-warranty battery replacements. Genuine Apple parts are also available for out-of-warranty repairs from Independent Repair Providers or through Self Service Repair.*

Get started with battery service.

Also, if a service provider uses non-genuine battery parts, the replacement battery may be:

  • Poorly designed or manufactured
  • A previously used battery
  • A damaged battery
  • An incorrect battery for your iPhone model

Any of the above could lead to insufficient battery capacity, improper fit or performance issues. Using non-genuine batteries may also result in unexpected behaviour after installation, after device software updates or while charging. Using non-genuine batteries may also lead to safety issues.

Genuine batteries are designed to work with iOS to function properly, including to report charge levels and battery health. Non-genuine batteries or repairs therefore won't be able to obtain battery health information.

* Independent Repair Providers have access to genuine Apple parts, tools, training, service guides, diagnostics and resources. Repairs by Independent Repair Providers are not covered by Apple's warranty or AppleCare plans, but may be covered by the provider's own repair warranty. Self Service Repair provides access to genuine Apple parts, tools and repair manuals so that customers who are experienced with the complexities of repairing electronic devices can perform their own out-of-warranty repairs. Self Service Repair is currently available in certain countries or regions for specific iPhone models introduced in 2021 or later. To view repair manuals and order parts for eligible models, go to the Self Service Repair page.


Parts and service history

With iOS 15.2 and later, and iPhone XR, iPhone XS and later models – including iPhone SE (2nd and 3rd generation) – you can go to Settings > General > About for the parts and service history of your iPhone. You can also find out whether the battery has been replaced. If the replacement was completed using genuine Apple parts and processes, "Genuine Apple Part" will appear next to Battery. If your iPhone hasn't been repaired, this section won't appear.


An Unknown Part  message will appear if the battery installation is incomplete or if the battery:

  • Was replaced with a non-genuine battery
  • Was already used or installed in another iPhone
  • Isn't functioning as expected

An additional message may appear that says "Apple has updated the device information for this iPhone". This means that Apple has updated the device information maintained for this iPhone for service needs, safety analysis and to improve future products.

These messages don't affect your ability to use your iPhone or your battery.

With iOS versions earlier than iOS 15.2, an Important Battery Message will appear instead of an Unknown Part message. You can find the message by going to Settings > Battery > Battery Health & Charging.
