It is no exaggeration to say that modern technology is leading all kinds of devices to go wireless. Smartphones, headphones, network connections, etc. are gradually realizing wireless transmission, and fully wireless charging of smartphones is just around the corner. Nonetheless, the operational safety of a wireless charger cannot be ignored, ensuring that your phone charges efficiently and gets the most out of it – which is what this article is about.
1. What is wireless charging?
Wireless charging is a technology that transfers energy from a charger to a device through an electromagnetic field, allowing devices to be charged without a physical connection. It mainly uses the principle of electromagnetic induction or magnetic resonance to achieve energy transmission.
2. What is Qi certification?
If you use a wireless charger with the "Qi" or "Qi2" logo, then charging is safe. On the other hand, if these signs are not present, you need to be extra careful.
Qi certification is a wireless charging technology standard launched by the Wireless Power Consortium (WPC). The core purpose of this standard is to ensure the safety, interoperability and energy efficiency of wireless charging products. Qi-certified products mean they have passed rigorous testing and comply with a range of rules, regulations and manufacturing requirements. To verify that a product is Qi certified, you can access the Qi Product Certification Database:

3. The importance of choosing Qi wireless charging
With efficiency and security at its core, the Qi standard is trusted by many leading global brands including Apple, Samsung, Google, Amazon, Belkin, Huawei, Xiaomi, vivo, OPPO, Honor, Tesla and Anker. Additionally, Qi keeps you and your phone safe with the following specifications:
1. Foreign Object Detection (FOD) function: Have you ever accidentally placed your keys or coins on the charging pad? Qi chargers can detect foreign objects and prevent accidental heating, thereby avoiding sparks or overheating caused by debris. The charger is able to distinguish whether it is a phone or another object that is being touched.
2. Heat monitoring function: It is never a good thing for a mobile phone to heat up, because it may cause minor or even serious damage to the mobile phone. Qi chargers are able to monitor device temperature while charging. Once the device overheats, the charger will automatically adjust or pause charging to allow the device to cool down. This helps keep the battery in good condition and prevents accidents.
3. Using wireless charger: There are many different brands of wireless charging mobile power / charger on the market, but the Qi charger has the unique features we mentioned earlier, including foreign body detection, heat monitoring, and interoperability with Qi products. Also, it is easy to carry, allowing you to escape the anxiety of a battery shortage.
4. Safe fast charging function: Qi charger is designed to provide appropriate power, ensure safe charging speed, and avoid damaging the device battery. Many products also support fast charging, so you don’t have to wait long to charge your phone.
5. Monitor battery health: Most smartphones come with settings to check battery health. Regularly checking battery status can help you detect problems early. If you notice a decrease in your battery's ability to store electricity, you may need to have it inspected or perform a self-check. Battery failure is often related to storage space, usage patterns and number of charges. Optimizing usage or adopting safer charging methods can often improve battery health.
6. Use a wireless charging stand with cooling function: Some wireless chargers are equipped with built-in fans or cooling systems, which can help dissipate heat while the phone is charging. A cooled charging stand is useful if you often charge overnight or use your phone intensively while charging. It helps keep your device cool and helps your battery stay in good condition for the long term.
7.Fully charge your phone: There is a common misconception about charging your phone: you should wait until the battery is exhausted before recharging your phone. However, this is not true. In fact, modern lithium-ion batteries are better suited to always being fully charged. Frequent short-term charging is better than charging from zero to full. So whenever you get a chance, put your phone on a wireless charger and it's great for your battery.
In conclusion, is wireless charging safe? Totally safe - especially if you use a Qi-certified charger and take a few precautions. Stick to Qi chargers with built-in safety features, monitor battery health through your phone settings, and consider using a cooled charging stand when charging for long periods of time to keep your battery fully charged at all times. Enjoy the convenience of wireless charging with confidence that your devices will keep running smoothly when used wisely.
