​ Short answer: Yes it can! If it's a 2-in-1/Y-cables. Let's look at why they are so dangerous and whether exceptions exist. ​ Factor1. What voltage is transmitted through the USB cable?​ ​Regular USB cables with any type of connectors (UsbC, micro Usb, UsbA etc.) if it is not broken or damaged cannot harm your device because safety is built into the USB standard and all USB devices are either able to accept 5V or simply won't turn on because the voltage is too low for opera

​The short answer is that it could be due to a cable, charging adapter, and/or an incompatible fast charging protocol. Let's take a closer look at each of these factors. ​ Situation : Your smartphone supports fast charging, but when connected to a charger, it charges slowly. Here are a few reasons for this unpleasant situation. Reason1. The charger and/or cable is defective. Try connecting using the same cable and the charger to another smartphone that supports fast charging

Short answer: No the fast charging doesn't harm it and let's figure out why. ​ To answer this question there are 3 factors to consider: First factor: Battery chemistry and its limitations. Smartphones most commonly use Li-Ion and Li-Pol batteries, which are very similar in terms of their design and chemical processes, although Li-Pol batteries may have slightly higher voltages (up to 4.35V). These two types of batteries are often referred to by the generic term, lithium batte
