Despite the fact that wireless charging has been used in consumer products for over a decade, there are still a number of misunderstandings about the technology—particularly concerning its safety—that may deter customers from making the transition. Moreover, wireless charging is deemed by tech companies like Apple and Samsung as the future of charging. When it comes to some of the most frequent wireless charging myths, we’re separating reality from fiction today.
One of the major myths about wireless charging is that it’s slow. The early version of Qi wireless charging only had a maximum charging power of 5 W, which is considered very underwhelming by today’s standards. However, advancements in the standard have allowed for power outputs of up to 15 W, which is more than the output of many wired chargers. A quite recent myth that has surfaced about wireless charging is that wireless charging can overheat your phone’s battery. Heat levels can be kept low enough to prevent battery damage with good design and electrical engineering. Both wireless chargers and smartphones must manage to charge power in order to prevent excessive heat accumulation in the phone’s battery when charging. Using wireless chargers made with high-quality components can prevent your battery from being damaged when charging.
Lastly, there is a common misconception that charging your phone wirelessly over the night can damage your phone. Many folks find that charging overnight is the most convenient option. However, some people are concerned that charging over long periods of time might lead to overcharging and inevitable battery damage. While this may have been accurate in the past, present smartphone batteries have a built-in battery management mechanism that turns off charging power as soon as the battery reaches 100%. No matter how long the phone is connected to the charger, it will be cut off from the charging power, ensuring that it does not overcharge.
