Lightning comparison to USB
Compare Lightning with USB for charging, data, accessory support, connector availability, certification, and the transition from Apple’s proprietary connector to USB-C.
| Factor | Lightning | USB |
|---|---|---|
| Connector ownership | Apple proprietary connector ecosystem | Open industry standard family maintained through USB-IF specifications |
| Charging | Supported on compatible Apple devices and accessories | Supported across a very broad range of devices, with USB-C supporting modern negotiated power delivery |
| Data | Supported for compatible Apple devices and accessories | Core USB function across many generations and device classes |
| Accessory certification | MFi certification is important for many third-party Lightning accessories | USB compliance and certification programs vary by product and implementation |
| Current device trend | Primarily existing Apple devices and accessories | USB-C is now used across newer Apple hardware and a broad cross-platform ecosystem |
| Best fit | Maintaining compatibility with existing Lightning hardware | New multi-platform devices, charging, data, and peripherals |

Lightning use cases
See where Lightning still makes sense for older Apple devices and accessories, and when USB-C or another modern connection is the better choice.
| Use case | Why Lightning fits | Better modern option |
|---|---|---|
| Older iPhones and iPads | The device may have Lightning as its native wired connector | Keep Lightning for that hardware; use USB-C on newer devices |
| Existing accessories | Some docks, audio accessories, remotes, and peripherals were designed specifically for Lightning | USB-C equivalent when replacing or upgrading the accessory |
| Charging existing devices | Lightning remains required on compatible older hardware | USB-C for newer Apple and cross-platform devices |
| Accessory data | MFi accessories can communicate through Lightning on supported iOS and iPadOS devices | USB-C for newer accessory ecosystems where supported |
| New purchases | Little reason to choose Lightning unless compatibility with existing equipment is required | USB-C is generally the more future-facing connector |
