iPhone 15 charging slowly? How to fast charge iPhone with USB-C
The charging landscape for the iPhone 15 and iPhone 15 Pro has undergone a significant transformation this year with the introduction of USB-C, replacing Apple’s proprietary Lightning port. This shift opens up a world of possibilities, allowing users to charge their iPhones with a wide range of USB-C cables and power adapters available online. In this guide, we explore the nuances of fast charging for the iPhone 15 and provide detailed insights on how to optimize charging speeds.
Understanding USB-C Compatibility:
With USB-C being an open standard, users have the flexibility to utilize nearly any USB-C cable in their possession. While the iPhone 15 comes with a high-quality woven braided cable in the box, it’s worth noting that any USB-C cable, including those labeled as ‘Android’ phone cables, can be employed. However, if your iPhone appears to be charging slowly, the culprit may be the charging brick.
Historical Context:
In the era when Apple included accessories in the iPhone box, the devices were accompanied by small 5-watt power adapters. Due to their longstanding inclusion, many of these adapters are still in circulation. Users possessing these adapters can continue using them with the iPhone 15 by pairing them with a USB-C to USB-A cable. However, it’s crucial to recognize that this combination will only charge the phone at 5W speed, resulting in a prolonged charging time, especially given the increased battery capacities of modern smartphones.
Unlocking Fast Charging:
To leverage the fast charging capabilities of the iPhone 15, a higher wattage charging brick is essential. While the iPhone’s USB-C port can technically receive power up to 27 watts, practical considerations suggest that charging speeds plateau above approximately 20 watts. With an Apple 20W USB-C power adapter and a USB-C cable, users can achieve impressive charging speeds, going from zero to 50% in about 30 minutes and zero to 100% in under 2 hours.
Diversifying Charging Options:
The realm of fast charging for the iPhone 15 is not confined to Apple accessories. Numerous higher-wattage USB-C charging alternatives exist in the market, offering enhanced convenience compared to Apple’s adapters. Notable among these is the dual USB-C compact charger from Anker, providing a safe and efficient charging solution. Importantly, users can explore power adapters rated higher than 20 watts, with the iPhone automatically adjusting to the maximum supported speed.
Harnessing MacBook Power:
An exciting aspect of the USB-C transition is the compatibility with MacBook power adapters. For instance, a USB-C MacBook power adapter rated at 60 watts or higher can be employed to fast charge the iPhone 15. This cross-device compatibility extends further; if a MacBook is connected to power, users can even utilize one of the laptop’s USB-C ports to charge their iPhone at near-full speed. The unification of charging cables allows users to streamline their charging setup, utilizing a single cable and power adapter for multiple Apple devices.
Conclusion:
As the iPhone 15 embraces the USB-C standard, users are empowered with newfound flexibility in charging options. From choosing diverse USB-C cables to exploring higher-wattage power adapters, the potential for optimizing charging speeds is vast. This comprehensive guide underscores the importance of selecting the right combination of cables and adapters to unlock the full fast charging potential of the iPhone 15, enhancing the overall user experience in a world where speed and efficiency are paramount.
