Today (Tuesday), Apple is expected to unveil a new lineup of iPhone 15 devices, with questions about market access in China and competition for the most valuable listed company in the world.

The iPhone accounted for more than half of Apple‘s sales, which amounted to $394.3 billion last year, but it faces new challenges with selling in China, which is the third largest market for the, California-based company.

Apple‘s latest phones are expected to contain new charging ports, titanium cases and cameras, but their debut at its headquarters in Apple Park at 10 a.m. (1700 GMT) will come at a time when the Chinese government has expanded some restrictions. To use iPhones.

Apple will also have to deal with Huawei Technologies, which was its primary competitor in China’s premium smartphone market.

Last week, Huawei began selling the Mate 60 Pro, an advanced phone that uses Chinese-made chips that some US lawmakers believe were manufactured in violation of US trade restrictions.

Huawei wants to gain an advantage over Apple, with additional features such as satellite connectivity that relies on the Chinese government-backed network. The current Apple iPhone lineup includes satellite capabilities, although it is intended only for emergency situations.

Apple is likely to focus on its new product lineup on Tuesday. The shift will be such that Apple customers will be switching from Apple’s proper Lightning cables to USB-C, a standard Apple already uses on laptops and some high-end iPads.

Analysts also expect new periscope camera technology that could give phones better zoom capabilities and titanium cases, in addition to upgraded chips. These “periscope” lenses can use mirrors or prisms to obtain a longer lens without having to make the camera unit much larger.

The biggest question today will be whether Apple keeps these features for a new, high-end device, and makes smaller upgrades to its cheaper models.

Apple is expected to increase the average selling price of a phone to increase its revenues, but the question is whether it does so by raising prices in all areas… or just the premium versions.

The global smartphone market declined from 294.5 million phones shipped to 268 million in the second quarter, but Apple’s shipments fell less than any major smartphone manufacturer, falling from 46.5 million phones to 45.3 million, according to data from Counterpoint Research. ».
