Apple has updated its flagship iPhone X handset with two more powerful models, one of which is larger than before.
The iPhone XS Max has a 6.5in (16.5cm) display. The iPhone XS has the same 5.8in-sized component as the original.
Apple said that its Face ID system now works faster than before, and is still unveiling other features.
There had been concerns that the relatively high £999 entry price of iPhone X would limit its appeal when it was announced a year ago.
But Apple said it had consistently proven more popular than either of the lower-priced iPhone 8 models. Market research firms suggest it also outsold rival companies’ flagship devices.
That helped propel Apple to become the world’s first company with a market capitalisation above $1tn (£768m).
However, China’s Huawei still managed to overtake it in terms of overall smartphone market share in the April-to-June quarter, putting Apple into third place.
“Huawei was able to overtake it because Apple is not playing in the mid and low ends of the market,” commented Francisco Jeronimo from IDC.
“But Apple is very well positioned in the premium segment, and we don’t expect that to change over the next 18 months.”
Earlier at its California event, Apple unveiled a new smartwatch whose display extends further towards its edges than earlier models.
The firm said the Watch Series 4’s usable screen was more than 30% larger despite the device itself having similar dimensions to its predecessor.
It also gains the ability to detect if its wearer has fallen and to take electrocardiogram heartbeat readings.
Apple overtook Xiaomi and Fitbit to become the world’s bestselling wearable tech company in the second half of 2017 thanks to strong demand for the last generation of its smartwatch. It has held on to the top spot ever since, according to IDC.
“The reason it performed so well is that many network operators are only willing to focus on smartwatches with their own [built-in cellular] connectivity,” said Mr Jeronimo.
“That’s why they are shipping about as many watches as the whole Swiss watch-making industry.”
Several insurance firms and employers already offer the Apple Watch because of its health-tracking features and its new facilities should add to its appeal.
Apple said that the Watch would warn users if it detected abnormally fast and slow heart rhythms, and added that it had already been given “clearance” by the US Food and Drug Administration.
“Getting FDA approval for health features on the new Watch underlines Apple’s leadership in wrist-worn tech,” commented Ben Wood from the CCS Insight consultancy.
“It’s an arduous process that no other consumer wearable company has successfully navigated.”
Apple added that a fall-detection facility had been made possible because of the introduction of “next-generation” gyroscope and accelerometer sensors that sampled data eight times faster than before.
If it believes the user has fallen and remained immobile for a minute or more, it will call the emergency services for help, if set to do so.
