There’s a lot of controversy over the battery of smartphones and tablets, especially as to the proper way to recharge them. Many experts say that we should avoid the practice – a commonplace – of letting the device charge overnight. In fact, the community also backs this type of recommendation.
But there are other experts who say there is no problem. This is the case of Kyle Wiens, head of iFixit, a repair company famous for its dismantling of expensive devices such as iPhones and top-of-the-line Galaxys. He states categorically that this is a myth and that there is no problem in leaving your cell phone charged at night.
“Having your phone plugged in at night doesn’t diminish the battery,” iFixit head Kyle Wiens told the site. “It’s all about cycle count, it’s all about how you actually use the battery — how much work you’re making the battery do.”
“In terms of the gradual erosion of battery life, what must be understood is that phone batteries are constantly in a state of decay,” a spokesperson for Anker, a company that makes battery and charger accessory, said. “Sleeping with a phone charging overnight will make no noticeable difference in the process.”
For the specialist in question, what really matters are the recharge cycles. But what a recharge cycle. That’s when the battery goes from 100% to 0% and then it’s completely full. This characterizes 1 cycle. But let’s assume your cell phone has reached 50% and have you recharged it? This corresponds to half cycle. I think you’ve figured out the logic.
According to him, all batteries currently used have perfect operation up to about 400 cycles. That is, during these 400 cycles, the battery of your cell phone will use its maximum capacity. Once it has passed this barrier, its ability to retain energy gradually diminishes.
And he went even further. He stated that people need to understand that smartphone batteries are in a constant degradation process since their first use. And it’s not the fact of not letting your smartphone charge during the night that will change that.
However, the specialist stresses that it is important to always use the original charger and cable, which came with the device. Using generic chargers or even other devices can cause damage to the battery and even to your health in more extreme cases. So, who do you think is right?
