iPhone 15 new C-port analysis: 15 and Pro 'plug in at the same time but at different speeds', is Apple strong enough to innovate on its own?

In 2023, we finally saw an iPhone that can be charged with a Type-C cable. To be honest, Xiao Lei was a little confused when he got these iPhones. The expensive and difficult-to-use lightning port finally disappeared. From now on, I can just pull a cord out of the drawer to power my phone.

But judging from recent comments from netizens, everyone seems to be very interested in the C port of the iPhone 15 series. Some are curious about its charging power, and some are curious. Does it really have a "password lock"? Others are curious about whether the Android charger at home can charge it, etc.

In this case, Xiaolei will give you details today Let’s test it out and see what little surprises the iPhone 15 series released this year has in the most basic and important “charging port”.

Very good, still a familiar "taste"

Obviously, Apple still does not mark its maximum charging power on the official website like Android manufacturers do, leaving only the sentence "about 30 minutes" "Can be charged up to 50%", but readers who are familiar with mobile phones know that the first 50% of the charging process of the mobile phone is the fastest, and once it reaches about 80%, it will enter trickle charging (in order to protect the battery, the charging power is reduced ), the charging time will be much longer.

So can the charging speed of the iPhone 15 series pass the current standards? Woolen cloth?

Before the official start, Xiaolei first introduces the devices participating in the test today: iPhone 15, iPhone 15 Pro, iPhone 15 Pro Max, Apple official 30W charging head, Zimi 65W (supports 65WPD protocol) charging head , Apple original charging cable, a Type-C data cable supporting 100W PD protocol, and power tester.

In order to ensure that the maximum power can be achieved during charging, three models The power of the models is kept at about 15% and the screen is turned off. The specific charging data is as follows:

Obviously, the charging power of the three models has not been improved compared to the previous generation. The charging speed is almost at the bottom at the moment, let alone compared with those Android phones with more than 100 and 200W. , even the 100-yuan phone can basically be fully charged in one hour. Obviously fast charging is not "high-tech". Even Apple can directly use the 65W or even 100W PD fast charging protocol, but Apple does not. In addition to saving money, Xiaolei really can't think of a second reason.

It can only be said that Apple does have some "disagreements" in this aspect. Want to make progress”. As for wireless charging, Xiaolei really doesn't have any thought or time to test it. Only Apple can do such a "horrendous" charging speed.

What surprises are there in the new C-port?

Of course, the entire iPhone 15 series has been replaced with Type-C ports. In addition to changes in charging, according to official descriptions, the current iPhone 15 series can also connect to a variety of peripherals, such as U disk high-speed peripherals. storage devices, 4K displays, microphones, and more.

In the early years, when Xiaolei was using iPhone 13 Pro, he suddenly discovered that the speed of transferring photos or files using the lightning port was very slow. In most cases, its transfer speed was not even as fast as AirDrop. Later, after a query, We know that the Lightning port only supports the USB 2.0 transmission protocol, that is, the theoretical transmission speed is 480Mbps, and the actual transmission speed is around 30MB/s.

Since the entire iPhone 15 series has discarded the lightning port, what about Are there any changes in transmission speed? (iPhone 15 and iPhone 15 Plus are USB 2.0, iPhone 15 Pro series is USB 3.0)

In order to verify Xiaolei’s conjecture, Xiaolei conducted three rounds of tests on it. Import RAW photos from the memory card, transfer large files from the computer to the phone, and transfer videos from the phone to the computer.

The first step is to import photos. The maximum read and write speed of the mobile hard disk used by Xiaolei is around 1500MB/s, and the size of a photo is around 110MB. The actual measured time spent by three iPhones in transferring these photos is: 126 seconds, 9.9 seconds, and 7.3 seconds, which means the transfer speeds are 43.6MB/s, 555MB/s, and 753.4MB/s respectively.

For comparison, Xiaomi Mi 13 Ultra also supports USB 3.0 transmission protocol The time required for transmission is 20.03 seconds (transmission speed is 280MB/s). It seems that the USB 3.0 of the iPhone 15 series is truly full-blooded 3.0.

The second is the computer introduction process. The output speed of Xiaolei's computer can reach 40Gbps (i.e. 4000MB/s) at the fastest, but for some reason the transmission speed is greatly reduced (perhaps it is an early system bug, and this has been true for many attempts) ). It was measured that the iPhone 15 took 85 seconds to import a file with a size of 3G, and the transfer speed was 35.2MB/s. The transfer time and speed of the iPhone 15 Pro and iPhone 15 Pro Max were both 38 seconds and 78MB/s.

The last part was also the most troublesome part for Xiaolei. Before, there were only two ways to transfer the videos shot on the mobile phone to the computer. One was to use WeChat to transfer, but this would severely compress the image quality and increase the transfer rate. It is also very low; the second is to directly connect the computer and the mobile phone with a data cable, but as mentioned earlier, the actual transmission speed of the lightning port is only 30MB/s, and it takes four to five minutes to transmit a video of about 6.7G, which greatly affects work efficiency.

The new iPhone 15 Pro and Pro Max will be 220 The seconds were successfully reduced to 8.58 seconds, and the speed increased by 28 times. This experience was something Xiaolei had never dared to imagine before. The iPhone 15 is still the same. It took more than 230 seconds to completely export the file to the computer. So if you often like to transfer some large files to the computer, you have to get a Pro even if you pay a little more, otherwise the transfer experience will be poor. It's really too bad.

By the way, the data cable included in the iPhone 15 series box only supports USB 2.0 transmission protocol, so users who often need to use iPhone to transfer or import files still have to purchase an additional full-featured Type- C data cable can basically reach its maximum transmission speed of 10Gbps.

Is Apple’s C port not C port?

Recently, Xiaolei has seen a lot of interesting remarks on the Internet, saying that using an Android charger to charge the iPhone 15 will burn out the phone. Some netizens even explained seriously that ordinary Type-C cables only have 9 cables. The iPhone 15 series has 11 interface pins, so it may burn out if it is incompatible.

There are also a group of netizens who claim that they cannot charge the iPhone 15 series using their old Android chargers at home, believing that this is due to Apple’s relevant interface restrictions. But as we can see from the previous article, Apple has not tampered with the C port. The charging head that Xiaolei uses every day can fully power it.

As for the "unable to power supply" situation expressed by netizens, Xiaolei It is speculated that the charging head or data cable used by this netizen does not support the PD protocol. In addition, the original chargers provided by some mobile phone manufacturers do not support the PD protocol. Therefore, when purchasing chargers for the iPhone 15 series, we only need to look for the word "PD". Agreement" and "not less than 30W" is enough. Today's charging heads are also very cheap. There is no need to spend four to five hundred yuan to buy the so-called Apple original charger.

As for how to choose the appropriate charging head and data cable, Xiaolei can briefly summarize it here: For charging needs, it is first recommended that everyone buy a full-featured Type-C data cable. Most of the current ones on the market Most data cables that support the 100W PD protocol are between 30 and 100 yuan. In fact, we almost don’t need to buy 100W data cables. However, the price difference between the current rated power of 100W and ordinary cables is not big, so it is a no-brainer to buy 100W PD data cables. That’s it. And after all, it is mainly for charging, so you don’t need to pay too much attention to the data transmission speed of the cable. This function will basically not be implemented with it.

If you also value transmission speed , you can give priority to the Thunderbolt 3 data cable, which can easily run the iPhone 15 Pro series and provide up to 100W PD fast charging. You can charge mobile phones, computers and other devices with one when you go out. Its price is mostly 50- Between 200 yuan, you can buy it according to your needs.

As for the charging head, there is nothing much to say. As long as the product page is marked "Support PD protocol" and the power is not less than 30W, as for those netizens who say that Android chargers cannot charge the iPhone 15 series, Xiaolei It is recommended to see if it supports the PD protocol, otherwise it will be in vain.

In general, the replacement of the C port on the entire iPhone 15 series is indeed very convenient for users. At least we no longer need to carry a separate lightning cable to the iPhone when we go out. The blessing of the USB 3.0 transmission protocol also makes it easier to Its application scenarios have become more abundant, but judging from the current charging speed, it is hard for Xiao Lei to believe that this is actually a mobile phone sold for more than 9,000 yuan.

It is undeniable that the configuration of the iPhone 15 series is indeed more advanced. It is getting closer and closer to mainstream flagship phones. It’s a bit funny to say that in the early years, the iPhone was the real benchmark product in the mobile phone market, but in recent years, it has gradually been separated by Android flagships. The proud A-series processors have also fallen behind due to heat dissipation and other issues. With Snapdragon and Dimensity processors, perhaps today’s iPhone only has one ecosystem left and iOS can compete with Android.
