At this autumn conference, Apple finally launched the iPhone 15 series models in response to the market.All replaced with USB-C portsnot only simplifies the difficulty of connecting iPhone to current Mac models, but also greatly reduces the trouble of users who can only charge iPhone with Lightning cable. What kind of benefits and disadvantages will this adjustment bring?
▲The iPhone 15 series finally has a USB-C port interface
First of all, let’s explain why the USB-C used by iPhone 15 and iPhone 15 Plus only corresponds to the USB 2.0 specification and the data transfer capacity is only 480Mbps, while the USB-C ports of iPhone 15 Pro and iPhone 15 Pro Max correspond to USB 3.0 specification, the data transmission speed can reach 10Gbps.
As for the charging specifications, all iPhone 15 series models are marked as being able to charge 50% of their power in 30 minutes using a 20W charger. This part is basically the same as the iPhone 12, iPhone 13, and iPhone 14 series. However, it may still vary depending on the specifications of the charger and charging cable.
They are both USB-C, so why are they different?
As for both using USB-C ports, why are there still differences in specifications?
the reason isEU requirementsIt just depends on the use of the same charging interface. For example, the micro USB, which was mainstream in the market at the time, was first used as a unified charging interface. Later, it was changed to USB-C in response to market demand. However, it did not stipulate the use of the same specifications and standards, only for cases where the charging power exceeds 15W. , there will be additional requirements to be compatible with the USB PD specification. Therefore, even if there are many mobile phones, game consoles, and laptops on the market that use USB-C as the charging interface, there are differences in actual corresponding transmission rates and power supply power.
On the other hand, USB-IF, which develops USB interface design andNot enforcedAll designed cables must be submitted for inspection and certification, and the specification design uses a large number of options. Therefore, even if they are USB-C cables or ports, the actual transmission and power supply specifications are different.
Until the recently proposed USB 4 2.0 version, due to the addition of higher power charging specifications, connecting cables and connection ports will be directly marked with corresponding wattage for corresponding high-wattage outputs, for example, up to 240W. However, since USB-IF still does not mandate that all cables must be submitted for inspection, it only states that consumers can choose suitable products through the corresponding wattage marked on certified cables. Therefore, it is still inevitable that consumers will use ordinary USB-C cables. When charging laptops and other products, it may not be possible to charge smoothly, or the cable may be burned due to poor quality.
▲USB-IF It was not until the recently proposed USB 4 2.0 specification that cables that comply with the specification certification can be directly marked with easy-to-identify data transmission capacity and power supply wattage, but it still does not mandate that all accessory manufacturers must submit the production cables for inspection
In addition, Intel has also changed from Thunderbolt 3 to USB-C interface design. However, compared to the USB-IF proposed specifications, many of them are added as options. Intel has incorporated all specifications into the design and added its own certification. Even if the Thunderbolt 3 specification is later open sourced, cables can be built using the Thunderbolt 3 specification even without using Intel chips.
The subsequent Thunderbolt 4 and Thunderbolt 5 basically integrate USB-IF and subsequently propose specifications. The difference is that Intel has added all the specifications and ensured through its own certification that the wires comply with the specifications. Therefore, Thunderbolt 3 and Thunderbolt 4 will also be relatively , and even the Thunderbolt 5 cables that will enter the market in the future are much more expensive. Even because different manufacturers use different covering materials and other designs, the actual price may increase even higher.
Therefore, although they may all appear to be USB-C ports, there may be significant differences in functionality due to different specifications and designs, which may even be reflected in the actual selling price.
▲Comparative data released by Intel shows that Thunderbolt 3, Thunderbolt 4, or Thunderbolt 5, which is about to enter the market, are all designed with a USB-C interface, and have completed the design specifications proposed by USB-IF, and in addition USB-IF has its own specification certification to ensure the reliability of Thunderbolt cables. However, USB-IF does not mandate that all USB cables must pass specification certification before they can be sold. Therefore, the market is flooded with many products that appear to be USB-C but do not conform to the specifications. The phenomenon of uneven quality of wires
Can the iPhone 15 series be charged with the USB-C cable of an Android phone?
Returning to the iPhone 15 series, which has all been replaced with USB-C ports, many people may be curious whether they can use the USB-C cable of an Android phone to charge the iPhone 15 series models?
The answer is yes, because the bottom layer adopts the specifications proposed by USB-IF, and USB cables of different specifications are still backward compatible, so even if they correspond to the USB 3.0 specification or natively adopt the Thunderbolt 4 specification The designed USB-C cable can still be used on the iPhone 15 or iPhone 15 Plus that only supports the USB 2.0 specification port, but charging and data transfer will operate according to the USB 2.0 specification.
▲As long as the USB-C cable and charger meet the standard design, it can be safely used to charge the iPhone 15 series models.
If you want the iPhone 15 Pro and iPhone 15 Pro Max to charge according to USB 3.0 specifications or transmit data faster, then the connecting cable must use products designed to comply with USB 3.0 specifications, which will naturally be more expensive.
There are rumors that it is necessary to use MFI (Made for iPhone) designed wires so that the wires will not affect charging or even cause damage to the phone. This is actually not accurate. To be precise, you should choose cables that comply with the USB-IF certification specifications. To put it in simpler terms, it is to choose companies with brand reputation to make cables, and avoid mass production, uneven quality, and even very cheap prices. Cables for sale (for example, a cable worth XX yuan at the night market).
Charging cables that usually have problems are mostly made of wires with poor conductivity quality or poor tensile resistance. There may not be much problem in initial use, but after long-term use such as pulling, curling, etc., it may cause internal damage to the wire. If the wire core is broken, it may not be able to charge smoothly at least, or it may cause unpredictable results such as short circuit, fire and combustion.
Therefore, we still call for charging cables to be as reputable as possible. Even the Lightning cables used by Apple in the past are still of varying quality, and there are also concerns about their safety.
What are the benefits of switching to the USB-C series iPhone 15 series?
The first advantage is of course that you can share the charging cable with your Android phone. If you need to borrow a charging cable from others temporarily, you basically don’t need to worry about the different specifications of the charging cable, unless the other party is using an older model that earlier adopted the micro USB charging port. Mobile phones, otherwise currently launched Android phones have basically adopted USB-C port design, and the difference is only in charging efficiency and data transfer rate.
Another benefit is that the iPhone 15 series is more convenient to connect to Mac models and Windows devices. All wired connection needs can be solved through a single USB-C cable, and it also allows the iPhone 15 to use more peripheral accessories. For example, on the iPhone 15 Pro and iPhone 15 Pro Max, you can use an external storage device to transfer data, or you can directly connect to the computer via USB-C for video shooting, and transfer the shooting content directly to the computer for storage, making it possible to create creative photos taken with the iPhone. It has more application flexibility, and you can even charge your Apple Watch directly with iPhone power through the Apple Watch charging cable designed with USB-C interface.
▲Replace the USB-C port and support the USB 3.0 specification iPhone 15 Pro or iPhone 15 Pro Max. You can directly connect peripheral accessories and storage devices also designed for the USB-C interface, or directly connect to Mac and Windows models. Use in conjunction
As for the downside, peripheral accessories built with the Lightning interface in the past will no longer be usable. Some accessories may continue to be used through adapters. For example, branded headphone accessories originally built with the Lightning interface can still be connected to Lightning via USB-C. The adapter cable can continue to be used, but if it is a battery protective case or an external game controller handle accessory, it will not be able to accommodate the space for the adapter accessory, so it will not be able to continue to be used.
Apple has switched to a USB-C port starting from the iPhone 15 series, which means that many peripheral accessories originally designed with the Lightning interface, such as headphones, cables, and speakers, may gradually enter the discontinuation stage, or directly convert to USB-C interface specifications, and as Apple gradually phase out older iPhone models in the future, accessory manufacturers may also stop producing Lightning cables.
But it shouldn’t cause too much of a problem in the short term. After all, Apple still sells iPhone 13, iPhone 14, and iPhone SE. Therefore, the Lightning cable will not officially enter history too soon, but other peripheral accessories may become more popular. Quickly move to USB-C interface design.
