If the user knows and remembers the impact of factors such as charging cycle, voltage level and temperature conditions on battery life, he will be able to extend the life of his smartphone battery. Dmitry Strinadyuk, head of MegaFon’s department of accessories, portable equipment and specialized equipment, told socialbites.ca.
Smartphone batteries have a limited number of charging cycles before their performance is expected to decrease. A cycle is charging the battery from 100% to 0%. According to Strinadyuk, the best option is to plug the device into the charger when it has at least 20% of the charge remaining, charge it to 100%, and unplug it immediately.
“This way, the battery will last significantly more charging cycles. The maximum number of cycles may vary depending on the smartphone model. For example, an iPhone battery retains 80 percent of its original capacity after 500 full charge cycles. It takes 800 for the capacity to drop below 80 percent.” More than 100,000 full charging cycles will be required,” said the expert.
Modern smartphone models are equipped with controllers that monitor the charging process. As soon as the battery is 100% charged, the current supply stops. It only continues after a certain amount of energy has been expended, so even a phone left plugged in overnight will stop charging due to the controller.
The expert said that it is not desirable to use a smartphone while charging because the battery will be charged and discharged at the same time. Active use of the smartphone while charging increases the load, which forces some battery cells to work constantly, leading to increased wear.
“Some modern models are equipped with bypass charging technology for situations where you need to use only one smartphone but do not want to damage the battery, for example, while playing games – in this case, the smartphone is powered by bypassing the battery. To avoid causing wear and tear on the smartphone battery,” He added.
Strynadyuk said it’s also important to understand that any high temperature can negatively affect the lithium-ion (Li-Ion) and lithium polymer (Li-Pol) batteries in a smartphone. The optimal temperature for charging the battery is room temperature 18-22 Celsius. You should not leave your smartphone in the sun or near a heating device, or even leave it charging.
