Who can do without their smartphone these days? The time spent on phone screens requires almost daily recharges. Suffice to say that the quality and robustness of the battery must be optimal…
For some time now, manufacturers have been offering wireless charging to make our lives easier! The use of these wireless chargers is enjoying undeniable success for practical reasons, but is it without risk?
Risks observed when using a wireless charger
British researchers from the University of Warvick demonstrated in spring 2019 that the use of these chargers can harm your cell phone . Does wireless charging really damage your smartphone battery? So let's take a look at the benefits and risks of using a wireless charger, as well as tips for extending the life of your phone.
The advantages of the wireless charger
Using a charging station definitely simplifies your life. Telephone cables are no longer lying around. The risk of biting by your pets disappears. You get less caught up in the son. The possibility of dropping and breaking your device disappears. The icing on the cake is that wireless chargers offer an aesthetic appearance.
How does the wireless charger work? A transmitter placed in the charging base transfers energy to the receiver of the phone's battery, using the principle of electromagnetism. This physical phenomenon is called inductive energy.
Two international standards coexist for inductive charging: the Qi standard and the PMA standard. The main distinction between these technologies is a different range of wavelengths. Currently, Qi technology dominates the global market.
Specialists advise keeping your cell phone battery between 20 and 80% charged to ensure the lifespan of your smartphone. This instruction is more easily achieved with the use of a Qi charger.
Furthermore, charging your device with a cable-free charger preserves the life of the lightning port. Repetitive plugging and unplugging damages this connector. A faulty port makes charging the device impossible. Thanks to the use of the wireless charger, this problem disappears.

Problems observed: do wireless chargers really damage your battery?
The study criticized wireless induction technology for reducing the number of charging cycles compared to using a wired charger. In reality, there is no evidence of the existence of this risk. This drop is rather due to energy-intensive applications. To prevent them from draining the phone too quickly, put these applications on standby.
Compared to charging with a wired charger, the temperature of the mobile increases by 3°, or even more when charging by magnetic induction. This excess heat can harm the durability of your smartphone battery. Temperature readings have demonstrated that the latter do not exceed 27° with a wired charger, while their temperature is around 35° with an induction charger.
The researchers also put forward the inconveniences linked to the incorrect positioning of the laptop on the charging station. The receiver and transmitter work best when placed close together. The further away they are, the more energy and heat they develop to successfully charge the phone.
However, security protocols have recently improved this aspect. From now on, charging of the mobile stops as soon as it heats up too much.
Doubts remain regarding the risks caused by electromagnetic waves. They do in fact produce a certain amount of radiation. However, manufacturers assure that they remain minimal and harmless to health.
Five tips to preserve the life of your smartphone
- In order to preserve the life of your battery, prefer to use chargers certified and recognized by the brand of your mobile. A wide variety of chargers exist. Choose a charger that properly dissipates the heat generated by charging.
- When charging your handheld terminal, remember to remove the case. The heat produced by loading can thus volatilize more easily and limit overheating.
- Avoid using your phone while its battery is charging. Relax, you will find healthy and beneficial activities without necessarily using your mobile.
- Make sure to position your phone correctly on the base.
- Refrain from placing it in an overheated room during induction charging. This only increases the temperature of your mobile.
Using a wireless charger in poor conditions can damage your smartphone's battery. However, if you follow the advice above and those of the manufacturer, you will ensure the longevity of your laptop. You will even want to change it before its battery weakens. Avoid low-end accessories and take a look at the site www.easycash.fr .
