According to the tech site Macotakara, the next generation iPhone will make fast charging incompatible with third party chargers. Apple has added support for ‘C-AUTH’ to its new iPhones’ charging specification; C-AUTH stands for ‘USB Type-C Authentication.’ This means Apple will include a new security check feature that stops fast charging from any third party chargers and cables, unless they have been licensed by Apple.
Apple is not the first to use this feature; it is a safe way to stop dangerous third party cables from damaging your phone, which may result in needing to replace your iPhone in the long run. However, Apple took things a little further by modifying the current C-AUTH standard. Currently, C-AUTH restricts fast chargers of 18 watts or more down to 5 watts to performance. With its new models, Apple will use C-AUTH to drop all third-party chargers to 2.5W.
Although this may seem like unwelcoming downside for the new iPhone models to come this year, Apple will be pairing their fast chargers with their phones. However, if you ever need an additional fast charger for your phone, you may be looking at $68-84 per charger.
