With the arrival of 5G, the requirements for all aspects of mobile phones have become more stringent, of which battery life is undoubtedly a crucial part. In addition to larger and larger batteries, higher and higher charging power has become imperative. In the first few years of smartphone development, although mobile phone charging has been developing, but the presence has been very low. No wonder, because for one thing, the battery capacity at that time was already small, and secondly, charging in the overall mobile phone experience is not as direct as the performance improvement and camera pixel increase, so it is understandable.
Now, mobile phone fast charging has undoubtedly stood in the C position in the whole experience of mobile phones. Since the launch of iPhone 8, the new iPhone has been supporting fast charging, you can use the USB PD fast charging plug can be used in 30 minutes to charge the power from 0% to 50%, but Apple has been only 5W power supply adapted to touch the stove adapter and Lightning to the USB-A cable, which means that the user wants to experience this function, you must spend extra money to buy a fast charging head and cable. charging head and cable. Until 2023 newer Apple's will be giving away fast charging charging plugs straight out of the box.
From the middle of 2020, 100W or more high-power fast charging entered the market, which even shortened the charging time to more than ten minutes. Xiaomi, OPPO, vivo, Huawei have all achieved wired fast charging with more than 60W power, which can be filled in about half an hour, and mobile phone charging completely says goodbye to the long wait. Recently, Xiaomi brought 200W wired fast charging and 120W wireless fast charging, which can charge the mobile phone display power from 0% to 100% in 8 minutes and 15 minutes respectively.
Faster and faster charging rate, making consumers, manufacturers, managers have to face three concerns:
1. the use of safety: safety will become an important concern, Samsung explosion that year gave the user the impact of too strong, and 100W fast-charging speed of more than the introduction of smart phones, will be in the follow-up to the issue of security to make a rigorous gatekeeping and interpretation.
2. For the impact of the battery: super fast charging will accelerate battery aging, shorten the cycle of the battery. Will it affect the charging equipment and shorten its service life? All these have to be coordinated and considered.
3. Charger size: the previous traditional 50W, 60W level charging head is not small, 120W charging head is equivalent to the weight of a mobile phone, so 200W super fast charging in the charging head of the solution needs to be standardised. Need to do some small and portable, only more convenient to use.
From the beginning of the 5W to today's 200W, the change is not just a literal number, the charging time has dozens of times the difference. The invention of fast charging has brought us a lot of convenience. Not only has the charging time been greatly reduced, so that our electronic devices can be more quickly restored to power, saving valuable time. Fast charging technology also reduces the wear and tear on batteries, extending their life. In addition, fast charging reduces the need for power, helping to conserve energy. The invention of fast charging has made our lives more convenient and efficient, and is a reflection of the times and market progress.
