About genuine iPhone batteries
All rechargeable batteries are consumables and have a limited lifespan — eventually their capacity and performance decline so that they need to be replaced. iPhone uses built-in, high-quality lithium-ion batteries. They're rigorously designed, tested, and manufactured to meet Apple quality and performance standards. These genuine Apple batteries have also been certified for safety.
Learn about your repair options
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. Independent Repair Providers also have access to genuine Apple parts.1
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. Genuine Apple parts are also available for out-of-warranty repairs from Independent Repair Providers or through Self Service Repair.2
Get started with battery service
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 won't have the ability to obtain battery health information.
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 to see the parts and service history of your iPhone, and you can see if the battery has been replaced. If the repair was done using genuine Apple parts and processes, you will see Genuine next to Battery.
With iPhone 15 and later using iOS 18, you'll see a Used message if the battery was already used or installed in another iPhone.3
After a new Apple battery has been installed, you'll see Finish Repair next to Battery until you finish the repair with Repair Assistant.
You'll see an Unknown
message4 if the battery:
Was replaced with a nongenuine battery
Isn't functioning as expected
With iPhone 15 and later with iOS 18, a genuine battery can be reused on another iPhone of the same model. A reused battery might not perform as well as a new genuine Apple battery. You'll see Used next to Battery for a genuine Apple part that was used previously in another iPhone.
You can see your battery’s date of first use, capacity, and cycle count in Settings > Battery > Battery Health.

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.
A previously used part might function in a different iPhone, but because of prior use or modification, the performance and quality might be inconsistent.
With iOS 15.1 or earlier, an Important Battery Message will appear instead of an Unknown message. You can find the message by going to Settings > Battery > Battery Health & Charging.
