Frequently Asked Questions
Why did my phone suddenly start charging slowly?
Common causes are a worn or damaged cable, an underpowered charger that doesn’t support your phone’s fast-charge protocol, or debris/damage in the phone’s charging port. Test with a known-good PD charger and cable, inspect and clean the port gently, and reboot your phone to rule out software-related throttling.
How can I test whether the cable or the charger is the problem?
Swap components: try a different high-quality USB-C or Lightning cable with the same charger, then try the suspect cable with a known-good charger. If charging speed returns with the alternate cable, the original cable is the problem. If not, try another charger. This isolates which piece is failing.
Will a higher-watt charger harm my phone?
No — modern phones negotiate power using USB Power Delivery or the device maker’s protocol. The charger and phone communicate and the phone only draws the wattage it can accept. Using a charger that supports the correct protocol and sufficient wattage simply allows the phone to charge at its designed fast rate.
