Hunt your assumptions, wireless charging does not spare the battery of your smartphone. On the contrary, it reduces it. In any case, this has been demonstrated by researchers from the American Chemical Society in a new study.
According to a study by Morning Consult (November 2018), autonomy is the number 1 choice criterion for consumers when they buy their smartphone. The life of the product comes in third place. For most users, the latest technologies that some call “gadgets” (facial recognition, fingerprint reader, wireless charging, etc.) hardly weigh on the scale. However, the directions taken by the manufacturers go against the grain.
A study conducted by researchers from the American Chemical Society reveals that wireless charging reduces the life of smartphone batteries. In other words, a “gadget” function affects two essential criteria (autonomy and sustainability).
Wire charging more reliable
According to the ACS study, the problem of wireless charging lies in temperature management. For optimal charging, the smartphone and charger must align perfectly. However, positioning the smartphone on the base accurately is difficult. This causes higher temperatures during charging and reduces battery life.
The temperature can therefore significantly affect the health (SoH) of the batteries and their lifetime. – ACS study –
To support their comments, the researchers compared the charge cycles of smartphones connected wired and others on wireless stations. They indicate that to maintain a healthy battery for as long as possible, the temperature during recharging must be between 15 and 40 ° C. The lower it is, the more the battery is spared.
The results of the study show that with wired chargers the temperature never exceeds 27 ° C. With a wireless charging system and a smartphone well positioned on the station, the temperature rises to 30.5 ° C and then decreases in the second part of the recharge. However, if the smartphone is not perfectly aligned, this peak of 30.5 ° C is maintained for nearly 70 minutes.
While these figures are not alarming, they nonetheless demonstrate that wireless charging is more damaging to the battery than wireline charging. The study does not specify whether fast recharge has been specifically researched. Reverse wireless charging is not included in the results of this research.
How to save your battery
To avoid damaging the batteries , the researchers give some practical advice. First, try charging the smartphone in a room where the temperature remains adequate. When charging, avoid launching applications too greedy. Finally, remove the protective shell even if the prop has compatibility with wireless charging. Finally, make sure that the smartphone is perfectly positioned on the station.
