Reasons for Not Charging/Unstable Data Transfer

A data cable failing to charge properly or providing unstable transmission is a very common and frustrating issue. The root causes can generally be grouped into three categories: physical connection problems, cable and accessory issues, and device-related problems. When encountering such issues, stay calm and troubleshoot step by step, following the order of “from external to internal, from simple to complex.”

What to do if the data cable gets hot while charging?

It is normal for a data cable to become slightly warm during charging or data transfer, as resistance generates heat when current flows through it. However, if it feels hot to the touch (uncomfortable to hold for long), that is an abnormal condition and should not be ignored. First and foremost: if the data cable or charger becomes excessively hot, stop using it immediately and disconnect all devices! Safety comes first.
