Wireless charging more harmful for batteries than wired charging: Researchers

[KomalJain]

With phone makers now offering a more premium glass build, wireless charging is being added into the mix not only for the sake of it but for the added convenience as well. The appeal of wireless charging has piqued over the past couple of years, but what effect do you think this charging method has on battery health? Well, researchers decided to find an answer to this question and found that the primary issue with wireless charging is the amount of heat it generates. They say that wireless charging could generate an unwanted amount of heat due to the proximity of the devices involved - the charger and smartphone. This heating is much worse than simple thermal conduction and convection. And it is well-known that batteries (not just lithium-ion ones) in general age rapidly in higher temperatures. This means extensive heating of the smartphone, with the Li-ion battery close to the back panel, could significantly influence the health of your battery. Their temperatures should not go upwards of 50-60 degree Celcius. In real-life tests conducted by researchers, smartphone charged via your conventional wired method reached a maximum average temperature of 27-degree Celcius over a charging period of 3 hours. Inductive charging method, i.e wireless charging, saw the temperature rise up to 30.5-degree Celcius both in perfect and misaligned positions. It was, however, observed that the temperature dropped later in the charging cycle. The researcher noticed a similar temperature increase for the charging pad, ultimately concluding that wireless charging does heat up your device more as compared to your wired means. This means it will affect battery health more than wired charging, so the latter is recommended over wireless charging. However, the added convenience of the wireless charging technology and the ability to simply place the phone on your nightstand to charge seems to trump these issues for most people.

who told you that it is a myth wireless or wire charging does not matters . wireless charging does not harm the battery at all .

The one who posted it is not mad for sure and also the one who researched about it.

they are mad

there is a reason why Samsung has provided the fan on their charging pad why dont you understand about it . should I show you what wireless charger I am using .

[Anonymous]

this is very wrong info

[Anonymous]

lower than 10 or higher than 40 degrees harms the lithium ion battery . I use wire less charging. do you know that wireless charger have cooling fan to keep the phone cool while charging the device . stop spreading wrong info about wire less charging . should I show you my wireless charger . only thing that damages the battery is either very hot climate or very sunny day or extreme cold climates .

this is why the phone back glass to dissipation the heat of wireless charging.

I have wireless charger there is cooling fan on it's back . in order to keep the device and charger cool .
wireless charging have many benefits
as for your concern do ask one of your friends about wireless charging.

as for the wire charging phone also heats up while you use the phone plugged in charge and you are using the phone also heats up but that amount of heat is produce by processor not by the battery . modern cell phone batteries have the protection layer in order to avoid disasters.
