The real touch-screen smart phone has been developing rapidly since 2007. Since then, iPhone has been making great progress. However, the momentum of smart phone brands such as Nokia and Motorola, which have always been dominated by positive physical buttons, is gradually fading away. The influence of Apple’s iPhone today is needless to say. Compared with the Android camp, the battery capacity of Apple’s iPhone has always been an unusual existence. No matter how crazily the competitors piled up the materials, apple always sticks to its own path and develops steadily step by step. Including fast charging technology, apple is not slow to follow its own pace. < / P > < p > so today we will not discuss the development of mobile phone performance. Xiaobian would like to talk about how the built-in battery capacity has evolved from the first generation of iPhone to today’s iPhone 12 series. Combined with the change of charging power, we can see the progress of iPhone in this respect in recent years. < / P > < p > first of all, I want to use a graph to visually reflect the battery capacity change from iPhone 2G to iPhone 11 Pro max, from 1400mAh of iPhone 2G to iPhone 11 Pro max For Max’s 3969mah, Apple has released 25 models with a time span of 12 years. Although the battery capacity span is not large, the change of charging power supported is also very stable. The attached charger only increases from 5W to 18W, and the supported charging power is only 5w-12w-18w. It’s just that the random ancestral 5W charger dominates most iPhone products, which is a bit conservative compared with the Android camp. < / P > < p > 2007 was the era of Nokia and Motorola. With the popularity of functional computers, people’s impression of smart phones is just like that in the above picture. The front is occupied by the screen and physical buttons, and all operations are completed by physical keys and stylus. Users can use physical buttons to complete the operation. Now it seems that the experience is not good enough. However, at that time, users were used to using such smart phones. At that time, charging didn’t receive much attention, because most of the time, it was charged once and could be used for several days. < p > < p > and in 2007, jobs revolutionized the first generation of iPhone, removing all the other physical buttons on the front, leaving only one home key. This time, jobs transplanted the functions of the computer to the mobile phone, which greatly improved the performance of the phone, and carried the largest 3.5-inch mobile screen at that time. At this time, the iPhone 2G battery capacity is 1400mAh, and users did not pay attention to charging at that time, because it was only the beginning. < / P > < p > the next year, the iPhone 3G was launched, which was just catching up with the launch of 3G. IPhone 3G supports the latest 3G network and can get a fast online experience at that time. But compared with the first generation iPhone, the battery has shrunk to 1150mAH. The iPhone 3GS was launched in 2009, but the battery capacity only increased by 50mah to 1220mah, and the charging power was still 5W. < / P > < p > the year 2010 is a special day for apple, because Steve Jobs brought the iPhone 4, which adopted a new design appearance and created a classic styling design. What’s important is that this is also the last press conference hosted by jobs. The battery power of the iPhone 4 has increased to 1420mah. Similarly, the iPhone 4S, released the next year, has a battery capacity of 1420mah. < p > < p > in 2012, under the leadership of cook, Apple launched the iPhone 5. For the first time, it increased the screen size from 3.5 inches to 4 inches, and adopted a three-stage shell design. The battery capacity was greatly upgraded to 1440mah. In 2013, the iPhone 5S and 5C were launched, and the battery capacity continued to increase to 1560mah, but the standard configuration was still 5W charger and a to lightning fast charging cable. It’s a coincidence that Xiaobian’s first iPhone was the iPhone 5S. At that time, it was still in school. Although the standard configuration was 5W charging head, there were many chargers supporting 5v2.4a on the market. Charging for the iPhone 5S can obviously perceive that the charging speed has become faster. Now think about the charging protocol of apple2.4a. < p > < p > in 2014, for the first time, apple enlarged the iPhone screen from the traditional 4-inch to 4.7-inch, and added a plus product line. Due to the increase of the screen, the capacity of the battery has also increased greatly, to 1810mah. The plus version also broke through the 2000mAh battery capacity for the first time, and the iPhone 6 plus even touched the ceiling of 3000mAh, which is the first time in the history of iPhone development. But The complimentary charger is still 5W. The good news is that the phone supports apple 2.4a charging, and you can purchase additional chargers to get faster charging. < / P > < p > in the following years to 2017, Apple has launched two models of iPhone 6S and iPhone 7, which also have plus version. The battery capacity of the basic model is about 1800mAh, and the plus version is between 2500mah and 3000mAh. There is little change in the battery and the charging is basically at the same level. < / P > < p > 2017 is the 10th anniversary of the launch of the iPhone, which is a special day for apple. At the conference, phone8 and 8p and iPhone x, which symbolize the 10th anniversary, were launched. The reason for this is that Apple supports the rapid charging of PD on iPhone for the first time. The battery of iPhone 8 is 1821mah. Apple announced to use PD charger with usb-c to Lightning can charge 50% of the iPhone 8 in half an hour. Since then, the saying that the iPhone PD can charge 50% in half an hour has spread. < / P > < p > in 2018, Apple launched the new iPhone XS series. All three new iPhones are full screen design, and the 6.5-inch iPhone XS Max has a battery capacity of 3174mah, which is the first time that the iPhone’s battery capacity has exceeded 3000mAh. The three new iPhones all support PD fast charging, charging 50% of the power in half an hour. However, due to the increase of battery capacity, it is found in the actual test that the charging power has exceeded 9V 2A 18W, and the power has even reached the height of 21W. This is not easy for apple, which has always been cautious in charging. < / P > < p > the new iPhone 11 series released in 2019 is a turning point in the development of iPhone. For the first time, the iPhone 11 Pro Series is equipped with C to lightning fast charging cable and 18W PD fast charger. Although the power of iPhone 11 Pro Series can reach 22W at this time, the standard fast charging is not easy for apple. < / P > < p > it was introduced at the press conference that plus is Apple’s large screen iPhone. Why is a bigger screen than plus? Max, which is the origin of the naming of iPhone XS Max and iPhone 11 Pro max, and since the screen has grown to 6.5 inches, the battery has also increased from about 1800mAh to 3000mAh + even touching the ceiling of 4000mAh, and the power has exceeded 22W. < / P > < p > the premise of providing fast PD charging for iPhone is to use the charger with usb-c output interface, and shake hands with 9V voltage when charging, but because of iPhone The battery capacity of 8 is small, so the actual charging power can not reach 18W. The charging head network found that the change curve of charging mobile phone with PD charger and 5v2.4a charger in standby mode is almost the same. That is to say, although the charging voltage can jump from 5V to 9V, the limited current of mobile phone cannot reach 2a, so it is 9V 12W for iPhone 8 PD instead of 18W. < p > < p > since 2007, Apple’s iPhone has been with us for 13 years. From iPhone 5, the screen has increased to 4 inches, iPhone 6 has expanded to 4.7 inches for the first time, and added 5.5-inch plus models, to 5.8-inch full-scale screen for iPhone x, 6.1-inch full-scale screen for iPhone XR, and finally 6.5-inch max level screen. The screen size of the iPhone has gone through several iterations, and the battery capacity has also increased from the most basic 1400mAh to 3969mah, and the charging power has experienced a dimension of 5w-12w-18w. From this, we can see that apple is very cautious about the increase of battery capacity and charging power. < p > < p > at 1:00 am on October 14, 2020, Apple released the iPhone 12 series, the first 5g iPhone of apple, which expanded the product line of iPhone to four for the first time, and the extra one is the currently smallest, lightest and thinnest 5g iPhone 12 Mini. Although the new iPhone hasn’t been put on sale since the launch, it can be found on the Internet that the battery capacity of four new iPhones is 2227mah, 2775mah, 2815mah and 3687mah. It is obvious that compared with the iPhone in 2019, the battery capacity of the 11 series has not increased, but has decreased Series 12 uses a 5nm chip, so the endurance performance is still worth looking forward to. < / P > < p > the iPhone 12 series no longer comes with charging head and headset, and the packaging content is only iPhone and C to lightning fast charging cable. If users need quick charging but do not have a quick charging head in hand, they can only purchase them separately. Charging head network will launch charging compatibility test of four new iPhones in the future. Which charger can be used for iPhone 12 provides fast charging and can feed the new iPhone, interested friends remember to pay close attention. Global Tech
