Today we’re going to talk about Apple’s new iPhone 15.
On September 12, Apple launched a new iPhone, iPhone 15 Pro.
This new iPhone 15 Pro uses a titanium alloy body as its selling point and is designed to attract users who pursue the latest iPhone every year or prefer to use the original model.
If you use a protective case or don't care much about small improvements in screen size, it may not be very attractive to the average user.
However, for those who upgrade to a new iPhone every year, this is a welcome upgrade option.
However, for users with protective cases, the need for upgrades may be lower.
The new iPhone 15 Pro abandons the stainless steel body and uses titanium alloy, reducing the overall weight by 19 grams.
However, some people worry that titanium may not be as durable as stainless steel.
Apple seems to want users to upgrade more frequently and purchase Apple Care Plus.
The iPhone 15 Pro is equipped with a 3x telephoto lens, while the Pro Max is equipped with a 5x telephoto lens, but for most users, the performance of the main lens is not significantly improved.
Apple's A17 processor offers some performance gains, but it's not a huge upgrade.
The iPhone 15 Pro uses a titanium alloy body, making it lightweight but potentially less durable.
The new action button provides additional functions such as mute switching, starting recording, and more.
The iPhone 15 Pro uses a USB-C interface and finally abandons the Lightning interface.
USB-C offers faster data transfer speeds, which is great news for users.
However, Airdrop speeds don't seem to improve, which is a shame.
The A17 Pro offers an AV1 codec, but I haven’t yet seen an app on the iPhone that requires AV1.
Today we will talk about the AV1 decoder, especially its application on Apple processors. If it launches this codec on the A17 Pro, it could be an upgraded version of the M3 or even the M4. It won't be until about one generation, or more likely the M4, that the M5 will be equipped with this AV1 decoder. In the future, Apple may also apply the AV1 hardware decoder to MacBook to achieve better acceleration.
However, as far as the iPhone is concerned, I haven't seen any apps that require AV1 yet. I think Apple incorporated this mainly to allow developers to take advantage of the AV1 accelerator, or to enable editing tools like Cut Screen to be tested on the iPhone. And when used directly on an M3 or M4 processor, it will be able to achieve excellent hardware acceleration.
But for the average consumer, there doesn't seem to be much advantage yet. Perhaps Apple is doing this because KZitem is gradually moving to AV1 streaming, which can save data for operators, and the AV1 hardware decoding part can help KZitem and telecom companies (such as AT&T, T-Mobile and Verizon) save a lot of money on data. . For consumers, as long as the experience is not much different, they will not actually feel much difference.
Apple also integrates the USB controller directly into the chip, which is a fairly unique technology. Apple uses the 3nm process to integrate USB 3 into the chip, which is difficult for other manufacturers to match. The advantage of this is that it is very energy-saving, while other Android manufacturers' USB 3 chips may use older process nodes such as 14nm or 7nm, and the power consumption may not reach as low a level as Apple's. Therefore, integrating the USB controller into the chip may be to achieve this energy saving effect.
In addition, Apple's ISP (Image Signal Processor) is very close to the USB chip, which allows it to instantly transmit camera signals out via USB 3. This technology may be useful for some professional cameras, but they may have overheating issues because they may still use more mature process nodes (such as 28nm or 14nm). The iPhone can continue recording without overheating because its chip uses a 3-nanometer process, a specialized technology that only Apple can achieve.
The iPhone 15 Pro is absolutely stunning and has some impressive pro features.
