Wireless Mobile Phone Charging: Convenience and Popularity! | ZONSAN
Wireless mobile phones are charging, no need to be complicated chargers and cables, which are becoming more and more popular! Simply put the front of the smartphone upside down on the charging board, you can charge the phone! Today, wireless charging can be described as everywhere.
Mainstream wireless charging technology
When it comes to wireless charging, everyone must first think of QI and Magsafe. The Magsafe charger has a maximum power of 15 watts, but only supports Apple and some Android phones. The Qi charger is suitable for all equipment with the QI logo, which is even more common.
The popularity of wireless charging technology has expanded the wireless charging market. In fact, wireless charging has a history of more than a century! Its working principle is based on magnetic resonance coupling, which is the first time by power pioneer Nicholas Tesla in the late 19th century. Although it starts slowly, the advantages of this technology are changing the appearance of multiple industries, especially in the field of IoT (IoT).
In today's era, wireless charging is over! But this progress also brings some challenges. For example, does wireless charging affect the battery life?
The working principle of wireless charging
1. Tight -coupled electromagnetic induction
Through the electromagnetic induction process of wireless charging, electricity is transmitted to the device. The magnetic field generated by the charging board interacts with the copper coil in the device, and the power is generated, and then charges the battery. The most common thing in the present is the tight coupling electromagnetic induction charging.
2. Scientific principles
If the charger is connected to the power supply, there will be AC (AC), flowing through the transmitted coil, and then receiving the voltage of the coil inside the device. The equipment converts this voltage into DC power (DC) and charge the battery.
3. The importance of alignment and distance
Wireless charging efficiency is highly dependent on the alignment and distance of the transmitter and receiver coil! The two coils must be fully aligned to achieve the best energy transmission. Most wireless chargers and equipment have built -in protection measures to ensure alignment, but it is still critical to put the device on the charger correctly!
The effect of wireless charging on smartphones
Wireless charging has become the standard function of Apple and most Android flagships and mid -range smartphones. But you may have heard that wireless charging may be harmful to the phone because it produces more heat than charging with the socket on the wall. In fact, this problem is much more complicated.
1. Increased calories
Wireless charging generates additional heat because the electrical energy conversion efficiency is low. The charging efficiency of cables is higher, while wireless charging efficiency is between 50-80%. The energy that does not change becomes calories. However, high -quality wireless chargers have the mechanism of regulating temperature and preventing mobile phones from overheating.
2. Charging speed
Wireless charging is usually slower than wired charging, but it is faster enough. Like the Magsafe charger, you can charge iPhone 14 Pro Max in 45 minutes to 50%.
3. Charging cycle
The charging cycle refers to the number of times the battery is completed and discharged. Over time, the charging cycle will reduce the battery performance and shorten life. To extend the battery life, try to only wireless charging when necessary, and do not over -charge. Moreover, using high -quality wireless chargers can reduce the negative impact of the charging cycle.
4. Compatibility
Selecting a wireless charger compatible with smartphones is super important, otherwise it may be slow to charge or even charge!
Tips for extending battery life
Want to extend the battery life of smartphones and consider these suggestions:
Keep battery battery balance! Try to make the battery battery of mobile phone between 20%and 80%, but this is the best battery life range.
Check the health status of the battery! Android phones can be applied with accounts and other applications. The iPhone has built -in battery monitoring tools.
Use cautiously charging wireless! Don't put your mobile phone on the wireless charging board for a long time to prevent excessive charging.
Avoid extreme temperature! The battery works best at room temperature, don't use mobile phones in extremely heat or cold environment.
Avoid playing games or watching videos when charging! This will increase battery heat and accelerate battery aging.
Reduce fast charging! Fast -charging calories are much, which may be unfavorable to battery health.
Invest in high -quality charging equipment! High -quality chargers and accessories can reduce excessive charging, overheating or short -circuit risks.
Avoid wireless charging all night! If you charge at night, consider using the socket on the wall, do not use wireless chargers to reduce the risk of excessive charging.
Through these suggestions, you can extend the battery life to the greatest extent when enjoying the convenience of wireless charging!
