If you charge using inappropriate and low-quality cables, the smartphone battery can run out very quickly. Technical director of the MTS Urent Powerbanks service Ilya Kazakov told socialbites.ca how to choose a cable so as not to damage the battery.
According to the expert, the problem is usually in the battery; we use the phone incorrectly and charge it incorrectly, which causes the battery to drain. To make sure your battery lasts as long as possible, you need to use the right charger and cable.
“The first and most obvious factor to consider is compatibility. Make sure the charging cable you choose is compatible with your device. If you have an iPhone, you’ll need a Lightning cable; if you have an Android phone, you’ll need a micro USB or USB-C cable. The wrong cable probably won’t even fit into your device’s socket, let alone charge it,” he explained.
Another factor is the output current.
“You can find the output current and voltage on the power supply body. If it produces 2A, then the cable should be taken at least for its current capacity. Otherwise, charging will take longer. Most budget charging blocks provide an output of up to 1.5A. With them, you can use cables for 1.5-2A. If the charger is capable of providing 2-2.5A, then the wire can be selected for 2-3A. At the same time, many smartphones support fast charging technologies; then you can choose a more expensive cable with an output current of 3A,” Kazakov added.
As for cable length, the rule of thumb is that the longer the cable, the higher the resistance of the cable cores and the greater the voltage drop across the cable. Thin, long cables can extend the charging time.
“At the same time, long cables are more convenient, but they get tangled easily. Short ones are easier to use, but they are not as flexible. For portable units, it is better to use cables of minimum length. In other cases, the optimum cable length is 1.5 meters,” the expert emphasized.
A quality cable should stand up to daily use without breaking or fraying. Nylon cables are generally more durable and flexible than plastic (PVC) cables, while rubber (TPE) cables may be better suited for outdoor use or extreme temperatures.
“At the same time, a thicker cable will be more durable and will carry more current than thin wires that heat up during charging,” Kazakov said.
