Is your iPhone 15 charging slowly? Is it heating up or refusing to connect? Maybe the cable is to blame. Many people still use old cables or low-quality adapters because they’re unaware of the damage they do to the battery over time. An iPhone 15 needs the right charging cable to work instead of a cord that just “fits.” We’ll tell you exactly what you should use and how you can get the best charging speed.
The iPhone 15 uses USB-C
Apple introduced the Lightning port with the iPhone 15 series. Most models now use USB-C for charging and transferring data. This means:
- Lightning cables won’t do the trick
- Old USB-A to Lightning bricks won’t work
- Only a USB-C cable can charge an iPhone 15 fully
Shifting to USB-C increases charging speed and improves compatibility, but you still need the right cable.
Why USB-C Matters for Fast Charging
The iPhone 15 supports USB-PD Power Delivery (PD), which ensures faster charging when paired with the right cable and adapter. Using a weak or old cable can slow things down.
Here’s what you need for high-speed charging:
- A high-quality USB-C to USB-C cable
- A 20W or higher USB-C power adapter
This setup takes your iPhone 15 from 0% to 50% in just 30 minutes!
