In this context, a recent technical report revealed that the answer is not what some expect, as modern phones do not actually allow for benefiting from both methods.
Smartphones operate via a sophisticated internal power management system that determines the most efficient power source. When the phone is connected to a USB cable and placed on a wireless charger at the same time, the device automatically selects wired charging, and turns off or ignores wireless charging.
This is because wired charging is faster and more efficient, so it is always given priority. The phone’s power circuits are designed to avoid conflicting power sources and prevent potential malfunctions.
Extra heat
Experts point out that combining wired and wireless charging may generate additional heat inside the device, which is not desirable. Excessive heat is one of the most important factors that affect battery life and quality in the long term. For this reason, manufacturers program phones to prevent this type of dual usage to protect the battery and internal components.
Each method has its uses
Although dual charging isn’t actually possible, each method has its uses. Wired charging is convenient when you need a quick charge, while wireless charging provides greater convenience and ease of use, especially while working or sleeping. Some users rely on the wireless charger to continuously power the phone on the desk, while they use the cable when fast charging is needed.
Combine the two methods
Even assuming the phone allows both methods, this could result in overheating of the device, additional stress on the battery, decreased charging efficiency, and potentially reduced battery life in the long term. This is why this scenario is avoided in modern designs.
In conclusion
Charging the phone via cable and a wireless charger at the same time is not practically possible in most modern phones, as the device automatically selects wired charging and turns off wireless.
The goal is to protect the battery and avoid overheating, not just random technical limitations. Thus, the best option is to use each method as needed, wired charging for speed, and wireless charging for convenience.
