If your iPhone is unable to use the fast charge feature, there may be several possible reasons:
< br >
1. Power adapter: Apple's fast charge function requires the use of a power adapter that supports fast charge. Make sure you are using an original Apple power adapter or a third-party power adapter that has been certified by Apple to be compatible with fast charge. Non-original or uncertified adapters may not provide enough current to support fast charge functionality.

2. Charging cable: In addition to the adapter, the charging cable is also an important factor affecting the fast charging function. Make sure you are using an original Apple charging cable or a certified third-party charging cable that is compatible with fast charge. A low-quality or damaged charging cable may not provide the required current and power.

3. Device support: The fast charge function also depends on the Apple device model you are using. Only devices that support fast charging can benefit from fast charging technology. For example, Apple's iPhone 8 and later models support fast charging, while older devices may not.

4. Software Settings: Sometimes, the software Settings of Apple devices may affect the fast charge function. Make sure your device has fast charge enabled and the latest operating system version. You can click on \"Settings\" > \"Battery\" > \"Power adapter
2. Apple's mobile phone cannot use fast charge because it adopts its own unique charging technology, namely Lightning interface and Apple's patented charging protocol. This charging technology is relatively slow compared to the fast charging technology of other mobile phone brands. 3. In addition, the iPhone's battery capacity is relatively small, so even using a fast charge will not significantly improve the charging speed. In order to ensure battery life and safety, Apple has chosen a more conservative charging scheme.
If users are after faster charging speeds, they can consider purchasing a third-party fast charger or using a wireless charger to improve charging efficiency.
Possible reasons are as follows:
1, the mobile phone suddenly not fast charging may be the charger failure, should be replaced with a suitable charger to try.

? 2, it may also be that the charging port is in poor contact, and it is necessary to plug the charging port out and then plug it in.
< br >
? 3, it may also be the battery of the phone is damaged, it should be taken to the mobile phone repair shop for inspection and maintenance.
1, the data cable, charger, charging interface and socket voltage contact is poor, voltage contact needs to be reinserted.
2, the temperature of the mobile phone is too high, the mobile phone has the thermal protection function, when the temperature is high, it will stop charging, if the battery is completely exhausted, it is recommended to use the original charger to charge for 5 minutes, and then check whether it is normal.
3, mobile phone battery aging, mobile phone because of long-term use, inside the battery will gradually aging, this time the use of fast charger is likely to appear in the mobile phone itself is too high temperature and can not charge the situation, which is a normal phenomenon.
