Importance of service 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 Authorized 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 a trained technician should replace an iPhone battery. Repairs performed by untrained individuals using nongenuine parts might affect the safety of the device or might cause improper function.
Depending on your location, you can get your iPhone battery replaced — in or out of warranty — by visiting an Apple Store or Apple Authorized Service Provider, or by shipping your iPhone to an Apple Repair Center. 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.*
Additionally, if a service provider uses nongenuine battery parts, the replacement battery might 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 nongenuine batteries might also result in unexpected behavior after installation, device software updates, or while charging. Using nongenuine batteries might also lead to safety issues.
Genuine batteries are designed to work with iOS to function properly, including to report charge levels and battery health. Therefore, nongenuine batteries or repairs won't have the ability 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 might 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 experienced with the complexities of repairing electronic devices can perform their own out-of-warranty repair. 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 models, and later — 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 if the battery has been replaced. If the replacement was done using genuine Apple parts and processes, "Genuine Apple Part" will appear next to Battery. If your iPhone hasn't been repaired, this section doesn't appear.
An Unknown Part message will appear if the battery installation is incomplete or if the battery:
- Was replaced with a nongenuine battery
- Was already used or installed in another iPhone
- Isn't functioning as expected
An additional message might 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.
