The iPhone is all anyone cares about when it comes to Apple earnings

Apple is due to release earnings today, and analysts will be watching closely.

Apple is due to release earnings today, and analysts will be watching closely, even though they expect the results from this quarter to be pretty boring.

The tech giant is expected to report US$44.9 billion in revenue over the past three months. But what analysts and Apple fans really want to know is any information about what's coming this fall, when Apple is expected to release its next models of the iPhone. That includes a rumored 10th-anniversary edition of the iconic smartphone - an "iPhone 8" or "iPhone X" - with an all-new design and a price tag that could top $1,000.

Reports based on leaks from Apple's supply chain indicate that the high-end phone will have an edge-to-edge, super-sharp OLED screen and may have a fingerprint reader embedded in the glass. Other models may keep Apple's current LCD screen. A recent leak that originated from Apple itself (through its documentation for its upcoming HomePod speaker) indicates that its next phones may also have wireless-charging, fast-charging and facial-recognition capabilities.

But a completely redesigned model of the iPhone may come with a downside: delays. OLED screens, in particular, are difficult to manufacture. Some worry Apple will be unable to keep up with demand for the phone.

Analysts will be looking closely at Apple's projections for the next quarter to try to determine how the company is thinking about its short-term future. Lower guidance for revenue in the fourth quarter - below US$49b - could mean Apple will delay all of its models or cut the prices of the LCD phones, UBS analysts Steve Milunovich and Benjamin Wilson said in an investor's note ahead of the report.

Experts say Apple's future depends a lot on this next generation of iPhones, as the smartphone industry faces slower growth and higher competition. Sales of the iPhone have been somewhat disappointing for several quarters, as consumers save their dollars for the new, redesigned model.

"Investor focus over the next two quarters should be on the iPhone 8 cycle," KeyBanc Capital Markets analysts said in a note to investors earlier this month.

In a survey of potential iPhone buyers, analysts at UBS found the greatest level of interest was focused in the high-end model, noting that respondents were more interested in the "iPhone 8" than they have been in Apple's last two iPhone generations.

If it takes Apple too long to get its phones to customers, it could hurt its performance in the all-important holiday season. Apple's chief rival, Samsung, just reported record-breaking profits despite a very tough year when it suffered the recall of its Note 7 smartphone. (Much of Samsung's success comes from its business selling smartphone components to other manufacturers, including Apple.) The strong quarter put Samsung in position to actually top Apple's profit, as Samsung reported about US$12.6b in profit. That's more than the projections of about US$10.5b in profit for Apple.

Plus, Samsung is already generating good buzz about its upcoming Note 8, due to debut later this month.

Any disruption of iPhone sales could be damaging to Apple, which has counted on strong smartphone sales to weather problems in the past. Now the company faces slowing demand, including in China, the world's largest smartphone market. Some analysts have pointed to China's market as a possible reason why Apple capitulated to Chinese government demands earlier this week to stop distributing apps that iPhone users downloaded to avoid government censorship.

The app store and other Apple services, such as Apple Music, have become an increasingly important part of the company's business as it looks for ways to keep users happier with their devices for longer. Services, the second-largest segment for Apple, make up 13 per cent of revenue. But the lion's share of the company's money is still tied to the iPhone, which accounts for nearly 63 per cent of its sales revenue.
