Many iPhone users who are new to fast charging often have questions about battery life: a large amount of current is input into the iPhone in a short period of time, and the battery will not be able to withstand one day and fail. In fact, in a strict sense, the scientific use of fast charge does not affect the battery life of the iPhone. As a professional manufacturer of data lines, Sinodec Industrial Co., ltd. in China provides customers with many high-quality iphone PD charger cables (USB C to USB lightning cable).
The iPhone uses a lithium-ion battery that works with lithium ion Li+ moving between the positive and negative terminals of the battery. During charge and discharge, the Li+ of the positive electrode is released to the negative electrode through the electrolyte and embedded in the carbon structure of the negative electrode. The more Li+ is embedded, the larger the battery capacity is. The opposite of the discharge process, the negative electrode Li+ returns to the positive electrode through the electrolyte.
When performing normal fast charging, due to the protection mechanism, the iPhone can limit the charging power to ensure the safety and longevity of the battery. The main reasons that really affect the iPhone's battery life are the following two points: 1. Charge the iPhone in a high temperature environment; 2. The iPhone has been over-discharged many times, resulting in damage to the carbon structure of the negative electrode. The battery capacity cannot be reduced due to the inability to embed sufficient lithium ions. Apple said in the official document: "Charging the device in a high temperature environment may further damage the device. When the battery exceeds the recommended temperature, the software may limit the charge after the battery reaches 80%. Even storing the battery in a high temperature environment may cause "Impossible damage." It is especially important to keep the equipment in a location where the ambient temperature is above 35 °C, otherwise the battery capacity may be permanently damaged."
In general, the optimal temperature for charging and unloading iPhone batteries is between 0°C and 35°C, so avoid battery heating when using fast or slow charging. Once the battery temperature is too high, stop it in time. Charge and remove the phone case to fully dissipate the iPhone. In addition, regular manufacturers will also set some protection “levels” in the fast charge charger. For example, the 18W PD charger mentioned in this article can automatically adjust the current while improving the compatibility of the charger based on PowerIQ 3.0 technology. In addition, there are five major safety protection measures: overcurrent protection, overvoltage protection, short circuit protection, over temperature protection and anti-interference protection.
The PD fast charger is not necessarily large in size Due to the larger current and voltage, the components inside the fast charge charger are also more complicated than the general 5W charger, which leads to the oversize of the finished product, which is one of the reasons why people do not want to use the fast charge charger. . However, with the development of technology in the past two years, more and more fast charge chargers have gradually become "small". Many Chinese manufacturers' 18W PD chargers are almost the same size and weight as Apple's original 5W chargers. It can almost reach the level of "fake the real thing", let you "lightly" enjoy the 18W fast charge. Due to market demand, China USB cable factory Sinodec Industrial Co., ltd. recently launched a number of PD charger cable that meet the needs of iphone fast charging. We accept wholesale and OEM services.
