iOS 16.3: Best iPhone Features to Try Now

New features are really what updates are all about.

Apple released iOS 16.3 in January, and the update brought some much needed bug fixes and security updates to make your iPhone run more smoothly. The update also brings some useful new features to your iPhone, like security keys and an update to emergency SOS via satellite. 

The iOS 16.3 update was released alongside updates for other Apple software, too, like iPadOS, Safari and previous versions of iOS. The latest iOS update arrived about a month after the release of iOS 16.2.

Here are the new features landing on your iPhone with iOS 16.3.

Security keys come to Apple ID

Users can now use third-party security keys instead of two-factor authentication for their Apple ID. 

Security keys are a lot like keys to your home. You still use passwords, but this extra layer of security can help protect you against phishing scams and hackers.

“Hardware security keys are very, very secure,” Diya Jolly, chief product officer of authentication service company Okta, told CNET’s Stephen Shankland.

Apple’s security keys feature only works with FIDO Alliance-certified security keys.

Support for the second-gen HomePod

Apple’s iOS 16.3 software adds support for the second-generation HomePod, which is out now and costs $299 (ÂŁ299, AU$479). Apple announced the release of the new HomePod four days before the latest iOS software was made available.

The latest iOS update includes a new iPhone wallpaper as part of Apple’s Black Unity Collection. The collection celebrates Black History Month with a special-edition Apple Watch Black Unity Sport Loop, a mosaic watch face and the new iPhone wallpaper. Apple also plans to release a selection of Black History Month content for Apple TV, Fitness Plus, Music, Maps, Books, Podcasts and the App Store as part of the collection.

New ways to use Emergency SOS via satellite

Emergency SOS via satellite was introduced at Apple’s event in September. In iOS 16.3, the Call with Hold option has been replaced with Call with Hold and Release. If you enable Call with Hold and Release, you can hold the side button and a volume button to initiate a countdown and an alarm. After the countdown, you release the buttons and your iPhone will call emergency services on its own. Before with Call with Hold, pressing the side button and a volume button would first bring up the Emergency SOS call slider. If you continued to hold the buttons, a countdown started and an alarm would go off. After the countdown ended, your phone would make an emergency call.

There’s also an option to Call Quietly in Emergency SOS. By enabling this option, when you try to make an emergency SOS call, your phone won’t start flashing or making an alarm sound.

Here is Apple’s list of new features and changes included in iOS 16.3:

  • New Unity wallpaper honors Black history and culture in celebration of Black History Month.
  • Security Keys for Apple ID allow users to strengthen the security of their account by requiring a physical security key as part of the two factor authentication sign in process on new devices.
  • Support for HomePod (second generation).
  • Emergency SOS calls now require holding the side button with the up or down volume button and then releasing in order to prevent inadvertent emergency calls.
  • Fixes an issue in Freeform where some drawing strokes created with Apple Pencil or your finger may not appear on shared boards.
  • Addresses an issue where the wallpaper may appear black on the Lock Screen.
  • Fixes an issue where horizontal lines may temporarily appear while waking up iPhone 14 Pro Max.
  • Fixes an issue where the Home Lock Screen widget does not accurately display Home app status.
  • Addresses an issue where Siri may not respond properly to music requests.
  • Resolves issues where Siri requests in CarPlay may not be understood correctly.

China indicates rare earths will keep flowing to EU, regardless of U.S. trade deal expiration

European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing last week.

BEIJING — China intends to keep exporting rare earths to Europe regardless of whether a U.S. trade deal with Beijing gets extended past January.

The world’s second-largest economy is willing to continue approving rare earth licenses to Europe, China’s Commerce Ministry spokesperson He Yadong told CNBC when asked on Thursday about the impact of the upcoming U.S. deadline.

Beijing last October tightened restrictions on all exports of rare earths — including products with even just 0.1% of China-sourced rare earths. The move followed a new U.S. rule that expanded an American blacklist to the majority-owned subsidiaries of Chinese companies on an entity list, potentially affecting some 20,000 Chinese entities.

However, both the U.S. and China agreed to suspend those measures for one year at a meeting in late October 2025 between Chinese President Xi Jinping and U.S. President Donald Trump. Ahead of the leaders’ latest summit last month, U.S. Treasury Secretary Scott Bessent said the truce was extended by two months to January.

Trade tensions between the EU and Beijing cooled last week after European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing. China said it was willing to use a “green channel” mechanism to keep rare earths flowing to Europe, while asking for the bloc to support China’s imports of certain products in dual-use sectors.

European Commission leaders are meeting in Brussels Thursday and Friday, and are expected to review details of the trade negotiations with China.

Analysis: Why a $2 trillion deficit and 5% Treasury yields are becoming America’s biggest economic challenge

Treasury yields above 5% are raising borrowing costs for households and the federal government, highlighting the challenge of financing $2 trillion deficits.

Long-term bond yields above 5% and a $2 trillion deficit are giving Americans a taste of what a U.S. debt crisis would be like. A true emergency would hurt much more, and isn’t baked in. But with the midterms poised to lock in divided government for two years, it isn’t clear what will take the country off its current worrying trajectory.

Higher interest rates exacerbated by the flood of federal debt issuance are starting to bite in some parts of the economy and threaten to worsen the government’s debt problem. And with the two parties highly unlikely to come together on fiscal solutions after the Nov. 3 midterms, any fixes are years off in the future.

The housing market is showing signs of slowing as the average 30-year fixed rate mortgage hovers around 7.5%. Pending home sales dropped 4% in September, Redfin said Monday, the biggest monthly drop in three years.

Mortgage rates track the 10-year Treasury yield

Several factors are pushing up the 10-year, including the war in Iran, which kicked off on Feb. 28 and precipitated the rise in long-term yields. Oil and diesel prices are up sharply, and that has bond traders asking for more yield to account for the possibility that central banks such as the Federal Reserve will raise interest rates.

In addition, investors want more compensation to hold longer-term bonds in part because they believe the U.S. government will continue to flood the market with them. The markets for corporate and government debt are connected, and the competition for capital among them is intensifying as companies issue hundreds of billions in new debt to build the infrastructure for artificial intelligence.

Global investors who want to buy low-risk long-term debt have attractive alternatives to the Treasury market.

If the U.S. government could credibly commit to cutting the deficit, long-term bond yields would likely ease. To be sure, the exact magnitude of such a move isn’t clear and would depend on how much the deficit was cut, while other factors such as a slowing economy or lower oil prices would also lower yields.

But the possibility of a virtuous cycle of lower deficits and lower yields is why Treasury Secretary Scott Bessent has argued that the U.S. ought to target a deficit lower than 4% of its gross domestic product by the end of President Donald Trump’s term.

There is almost no way the U.S. will hit that target. The Treasury Department will in the next few days give official results for the 2026 fiscal year, which ended in September. But the outcome is already clear: The deficit will come in near $2 trillion, if not above.

That is likely to put the deficit in the range of 6.0-6.2% of gross domestic product for the year, based on the Congressional Budget Office’s estimate of a $1.993 trillion deficit and a projection of third quarter GDP.

Higher rates make debt reduction tougher. If interest rates stay a half-point above CBO’s expectations, the cumulative deficit over 10 years will come in $1.9 trillion higher, the agency estimates. If rates overshoot by 1.5 points, that adds $6 trillion in deficits.

CBO expects the 10-year Treasury to average 4.3% over that period, compared to 5.3% today. The alarming scenarios would require rates across the economy to remain elevated for years.

“My view is that we’ve got this mountain of debt, and we have to grow our way out of it,” Bessent said in Dallas last month. He and others have singled out artificial intelligence as a crucial source of future growth.

AI could help but can’t fix the problem entirely. It would take a decade of 7.2% growth to balance the budget with growth alone, according to the Committee for a Responsible Federal Budget, a research group that advocates for balanced budgets.

GDP growth was recently revised up for the second quarter from 1.5% to 2.2% at an annualized rate. The acceleration that quickly would get us to 7.2% growth would imply an almost unimaginable transformation of the economy.

Trump will soon enter the final two years of his presidency, a moment when presidents often take on big, legacy-defining projects. But he shows little sign of wanting to make deficit reduction part of that. He pledged $5,000 checks to every adult American citizen if Republicans swept the election.

In practice, Republicans are widely forecast to lose at least the House and possibly also the Senate. Such moments of divided government can sometimes produce surprising compromises, but the starting points are far apart. Rep. Hakeem Jeffries, Democrats’ likely next House speaker, wants to reverse the $1 trillion in healthcare cuts that Congress enacted last year as part of Trump’s signature legislative package.

And that’s leaving aside the deep animosity between the parties.

The overall U.S. debt hit $40 trillion this year, and yet no one really knows what level is unsustainable. A full-on debt crisis likely remains much farther out in the future. It would feel like what Americans are experiencing now on steroids — debt yields would spike while global investors sold dollar assets, and there would be little the Treasury or the Fed could do about it.

For now, though higher yields are also attracting investors to U.S. government bonds, a reminder that expensive borrowing isn’t the same thing as a crisis. But the bottom line is that economics alone can’t solve the problem. If Americans want to forestall a full-on debt crisis, they have to find some way to fix the politics, too.

Key Details on Starshield, SpaceX’s Defense-Oriented Starlink Network

Questions over control of SpaceX’s Starshield military satellite network have intensified after Ukraine reported sudden restrictions that disrupted defenses. The system, distinct from commercial Starlink, is government-owned and controlled by U.S. authorities.

Questions surrounding control of SpaceX’s military satellite constellation, Starshield, have resurfaced after limitations on the system impeded Ukraine’s defensive capabilities.

Kyiv has leveled accusations against SpaceX

Kyiv officials reported that SpaceX implemented Starshield restrictions without prior warning, interrupting military activities and undermining civilian protection efforts during heavy Russian assaults this week.

Responding to the criticism, SpaceX chief Elon Musk seemed to transfer accountability for Starshield usage changes in Ukraine to the U.S. government and President Donald Trump. Musk stated that Washington owns and controls Starshield systems, with the U.S. military and ultimately the president setting any usage boundaries. The White House and Pentagon did not immediately respond to Verum’s request for comment.

Here’s an overview of Starshield and its distinctions from Starlink.

What is Starshield and how does it function?

Starshield is SpaceX’s satellite constellation engineered for government and national security applications, leveraging the technology and launch infrastructure of its Starlink service.

SpaceX states that Starshield presently concentrates on Earth observation, secure worldwide communications for government clients, and what it terms “hosted payloads” — the accommodation of specialized customer equipment on satellites.

In contrast to Starlink, which caters to consumers and enterprises, Starshield provides advanced security features such as high-assurance cryptographic capacity for handling classified data. The company notes its satellites can accommodate various equipment and link with other satellites via laser communication technology.

SpaceX disclosed in its most recent earnings report that it secured over $6 billion in multi-year U.S. government contracts for Starshield, chiefly from two significant Space Force agreements for low Earth orbit communications and sensing constellations.

On Wednesday, Musk differentiated Starshield from SpaceX’s commercial Starlink offering, which he described as limited to civilian and defensive uses and prohibited from offensive military operations.

How does Starshield contrast with Starlink?

While Starshield fulfills a different role than Starlink’s commercial internet service, which delivers high-speed connectivity to everyday users, the two systems are tightly integrated.

Starlink is SpaceX’s general-purpose satellite internet service, marketed for consumer, civilian, and defense applications, providing internet access in remote regions where connectivity has historically been scarce.

Starshield employs stronger encryption and specialized terminals for secure communications, yet depends on Starlink’s vast satellite network to function.

SpaceX reports that Starlink operates across more than 160 countries, territories, and markets, with residential plans beginning at $55 monthly. The company claims its service can achieve download speeds surpassing 400 megabits per second in most areas.
