Apple is also expected to announce new Apple Watch models, with low-end and high-end iPads, and more Macs also expected either at this event or another one later in the year.
But this year's iPhone models arrive as consumers lower their spending due to inflation pressures.
Apple typically unveils its new iPhone models at launch events around September and this year it will be an online-only event, in line with others since the pandemic began. Past rumors suggested a September 6 launch date, with sales starting on September 16.
Apple will also unveil the Watch 8 series, along with a rugged model aimed at extreme sports users. This will feature a bigger display area, a more shatter-resistant screen, a tougher frame, and a bigger battery. The rugged model will be called the Apple Watch Pro, and will have a Pro-level price tag of as much as $900 or $999 -- well above the entry level $399 model. A low-cost Apple Watch SE is also mooted for the September 7 event.
The iPhone 14 launch, if it happens on September 7, will take place in the same week that Apple staff return to the office for at least three days a week, starting on Monday, September 5.
CEO Tim Cook's memo to staff, viewed by the Financial Times, said that all staff at its Cupertino headquarters must come in on Tuesday and Thursday plus one other day nominated by team managers. This is a pilot return-to-office program and follows several earlier attempts that were delayed by new variants of COVID-19.
