Apple's new ultra-thin iPhone Air will be officially launched on Friday, and some subtle details about this device are worth paying attention to. Here are five important things to know about the iPhone Air:

1. As previously rumored, the iPhone Air is only equipped with a single speaker. The earpiece on the top of the fuselage doubles as a speaker, but there is no speaker on the bottom of the fuselage. The openings on both sides of the USB-C interface are actually microphones. If you need stereo sound effect, you need to use it with AirPods or other external speakers.
2. The position of the Dynamic Island on the iPhone Air on the display is slightly lower than that of the iPhone 17 and iPhone 17 Pro models. This is mainly due to the internal structural adjustments brought about by the ultra-thin body design.
3. iPhone Air’s data transmission only supports the USB 2 standard, with a maximum speed of 480 Mbps, while the iPhone 17 Pro model supports USB 3.2 Gen 2’s 10 Gbps high-speed transmission.
4. Officials say that the iPhone Air can be charged to 50% in about 30 minutes, while the iPhone 17 Pro series only takes about 20 minutes. Achieving these charging speeds requires the use of higher-power chargers and cables. In addition, the iPhone Air’s MagSafe wireless charging power is up to 20W, which is lower than the 25W of the iPhone 17 Pro series.
5. The iPhone 17 Pro series is equipped with the A19 Pro chip with a 6-core GPU, while the iPhone Air has a 5-core GPU, so the graphics performance will be slightly reduced.
