Apple opens new tab on Monday unveiled its long-awaited, artificial intelligence-boosted iPhone 16 and promised improvements in its Siri personal assistant as it rolled out new software, beginning in test mode next month, Reuters reported.

"The next generation of iPhone has been designed for Apple Intelligence from the ground up. It marks the beginning of an exciting new era," Chief Executive Tim Cook said at a product launch.

Shares of Apple closed barely changed for the day at $220.91. Apple's event came hours before China's Huawei launches a tri-fold phone, underscoring the competitive challenge the iPhone maker faces. Apple has yet to announce an AI partner in China to power the 16s.

Apple and technology companies around the world are racing to add AI to products, and phones are expected to be among the most important battlegrounds. The Cupertino, California-based company also is betting the AI feature will drive consumers to upgrade amid a slowdown in iPhone sales.

Apple Intelligence, the company's AI software, will be used to improve Siri as well as enhancing features such as understanding and identifying objects captured by the phone camera, executives said.

A test version of Apple Intelligence will be available in the U.S. version of the English language next month. It will be available for other localized versions of English in December, with versions in languages including Chinese, French, Japanese and Spanish next year. Features including improvements to Siri will be rolled out over time, Apple said. It did not say, however, when it would move beyond test, read the report.

The iPhone 16 and 16 Plus will cost the same as models they replace and use a new chip and an aluminum case. A customizable button that can control the camera was one of the most touted hardware features in a format that looks similar to previous models.

The higher-end 16 Pro and 16 Pro Max are made from titanium and have more AI capability, such as offering suggestions on how to set up a photo shoot more effectively and audio-editing capabilities aimed at professional-level video production.

Apple's new iPhone chips use the latest version of Arm's architecture that includes specific features to speed AI applications.

"Existing iPhone users who have had their device for 3-4 years will definitely be enticed to upgrade, even if some things are rolling out later, as this will future-proof their device for AI," said International Data Corp analyst Nabila Popal.

Still, several analysts described the delays in features as keeping many potential buyers on the sidelines initially.

"You might see people wait a little bit to see how these things work out, how well they function, and then they'll start to investigate it. But I don't think we'll see the mad rush that we've seen in years past," said TECHnalysis Research founder Bob O'Donnell.

By comparison, Huawei's website showed on Monday that it had garnered more than 3 million pre-orders for its Z-shaped tri-fold phone ahead of its official unveiling. This underscores Huawei's ability to navigate U.S. sanctions and solidifies its position against Apple in China, where consumers are hankering for more AI features and are willing to pay for them, Reuters reported.

Apple also unveiled new Watches and AirPods with health-focused capabilities, as well as hardware-design improvements. Apple highlighted the Watch's ability to discover longer-term health conditions such as sleep apnea as well as detecting and responding to emergencies such as a fall.

As it updated AirPods, Apple rolled out hearing-aid features that it has submitted for U.S. regulatory review.

Apple fans globally have been waiting to see the new phones with AI. IPhones accounted for more than half of Apple's $383 billion sales last year.

"While Android phones may have some of these features, Apple has packaged them well and will be able to market them far more broadly," said D.A. Davidson analyst Gil Luria.

China offers particular challenges to Apple.

"Apple fell out of the list of top five smartphone vendors in China in Q2," said eMarketer senior technology analyst Gadjo Sevilla. "It was the first time that China's domestic smartphone firms held all five spots. Since Apple Intelligence still needs to be approved by Beijing for a rollout in China, it will likely not initially be a key driver for adoption in the region."

In China, Apple aggressively slashed prices earlier this year, prompted by government restrictions and increased domestic competition, read the report.

The iPhone 16 lineup is the first Apple smartphones designed around these AI features though those are expected also to be available on iPhone 15 Pro and Pro Max, the top-end versions of the previous-generation devices.

Rivals including Alphabet's, opens new tab Google are also showcasing AI features to try to upend Apple's dominance in the high-end smartphone market.

Google, developer of the Android operating system which competes with Apple's iOS, focused its Pixel smartphone rollout event in August on AI features including Gemini Live, which allows users to hold live voice conversations with a digital assistant. Many of the AI features Google announced were also rolled out to the Android-based devices made by manufacturers such as Samsung, opens new tab and Motorola, opens new tab.

In June, one week after its developer conference, Apple said it would delay the release of AI-powered features in Europe due to European Union tech rules.

Huawei has scheduled an official announcement of its Mate XT Z-fold phone on Tuesday in China, Reuters reported.

Apple’s latest iPhone with its A18 chip, which is set to be unveiled at an event on Monday, has been developed using SoftBank-owned Arm’s newest V9 chip design, the Financial Times newspaper reported on Saturday.

Apple is set to host its fall event on Sept. 9 at its headquarters in Cupertino, California, where it will likely unveil a series of new iPhones and updates to other devices and apps, Reuters reported.

Apple signed a deal with Arm in September last year that "extends beyond 2040" in a boost for Arm for chip technology.

Arm had said in July that its V9 chip accounts for 50% of smartphone revenue.

Arm owns the intellectual property behind the computing architecture for most of the world's smartphones, which it licenses to Apple and many others.

Apple uses Arm's technology in the process of designing its own custom chips for its iPhones, iPads and Macs.

The two companies have a long history - Apple was one of the initial companies that partnered to found the firm in 1990, before the release of its "Newton" handheld computer in 1993, which used an Arm-based processor chip.

The Newton flopped, but Arm went on to become dominant in mobile phone chips because of its low power consumption, which helps batteries last longer.

Pavel Durov, the Russian-French billionaire founder and CEO of the Telegram messaging app, was arrested at Bourget airport outside Paris on Saturday evening, TF1 TV and BFM TV said, citing unidentified sources.

Durov was travelling aboard his private jet, TF1 said on its website, adding he had been targeted by an arrest warrant in France as part of a preliminary police investigation, Reuters reported.

TF1 and BFM both said the investigation was focused on a lack of moderators on Telegram, and that police considered that this situation allowed criminal activity to go on undeterred on the messaging app.

Durov faces possible indictment on Sunday, according to French media.

The encrypted Telegram, with close to one billion users, is particularly influential in Russia, Ukraine and the republics of the former Soviet Union. It is ranked as one of the major social media platforms after Facebook, YouTube, WhatsApp, Instagram, TikTok and Wechat.

Telegram did not immediately respond to a Reuters request for comment. The French Interior Ministry and police had no comment.

Russian-born Durov founded Telegram with his brother in 2013. He left Russia in 2014 after refusing to comply with government demands to shut down opposition communities on his VKontakte social media platform, which he sold.

"I would rather be free than to take orders from anyone," Durov told U.S. journalist Tucker Carlson in April about his exit from Russia and search for a home for his company which included stints in Berlin, London, Singapore and San Francisco.

After Russia launched its invasion of Ukraine in 2022, Telegram has become the main source of unfiltered - and sometimes graphic and misleading - content from both sides about the war and the politics surrounding the conflict, read the report.

The platform has become what some analysts call 'a virtual battlefield' for the war, used heavily by Ukraine's President Volodymyr Zelenskiy and his officials, as well as the Russian government.

Telegram – which allows users to evade official scrutiny - has also become one of the few places where Russians can access independent news about the war after the Kremlin increased curbs on independent media following its invasion of Ukraine.

The Russian foreign ministry said its embassy in Paris was clarifying the situation around Durov and called on Western non-governmental organisations to demand his release, Reuters reported.

Russia began blocking Telegram in 2018 after the app refused to comply with a court order to grant state security services access to its users' encrypted messages.

The action interrupted many third-party services, but had little effect on the availability of Telegram there. The ban order, however, sparked mass protests in Moscow and criticism from NGOs.

TF1 said Dubai-based Durov had been travelling from Azerbaijan and was arrested at around 8 p.m. (1800 GMT).

Durov, whose fortune was estimated by Forbes at $15.5 billion, said some governments had sought to pressure him but the app should remain a "neutral platform" and not a "player in geopolitics".

Telegram's increasing popularity, however, has prompted scrutiny from several countries in Europe, including France, on security and data breach concerns.

Russia's representative to international organisations in Vienna, Mikhail Ulyanov, and several other Russian politicians were quick on Sunday to accuse France of acting as a dictatorship - the same criticism that Moscow faced when putting demands on Durov in 2014 and trying to ban Telegram in 2018.

"Some naive persons still don't understand that if they play more or less visible role in international information space it is not safe for them to visit countries which move towards much more totalitarian societies," Ulyanov wrote on X.

Elon Musk, billionaire owner of X, the social media platform formerly known as Twitter, said after reports of Durov's detention: "It's 2030 in Europe and you’re being executed for liking a meme."

Robert F. Kennedy Jr, who on Friday abandoned his U.S. presidential campaign and endorsed Republican Donald Trump, said on X after the reports that the need to protect free speech, "has never been more urgent."

Several Russian bloggers called for protests at French embassies throughout the world at noon on Sunday.
