Adaptive Power in iOS 26 Could Boost Your iPhone Battery Life, but It’s Not on All Models

The new iPhone 17 models get better battery life, partly through this iOS 26 feature that is available on other iPhones, too.

When Apple announced the iPhone 17, iPhone 17 Pro and iPhone Air earlier this month, it touted improved battery life across the board and “all-day” battery for the iPhone Air, which has a physically smaller battery to fit inside its thin design. Some of that is due to physically larger batteries, but a new feature called Adaptive Power in iOS 26 is also contributing. And it’s available on any iPhone capable of running Apple Intelligence. 

Currently, the iPhone uses as much power as it needs to perform its tasks. You can extend the battery life by doing a number of things, such as decreasing screen brightness and turning off the always-on display. Or, if your battery level is starting to get dire, you can activate Low Power Mode, which reduces background activity like fetching mail and downloading data in addition to those screen adjustments. Low Power Mode also kicks in automatically when the battery level reaches 20%.

If Low Power Mode is the hammer that knocks down power consumption, Adaptive Power is the scalpel that intelligently trims energy savings here and there as needed. Based on Apple’s description that accompanies the control, the savings will be felt mostly in power-hungry situations such as recording videos, editing photos or perhaps even playing games:

“When your battery usage is higher than usual, iPhone can extend your battery life by making performance adjustments, such as lowering display brightness, allowing some activities to take longer, or turning on Low Power Mode at 20%.”

Apple says Adaptive Power takes about a week to analyze your usage behavior before it begins actively working. It works in the background without needing any management on your part. The iPhone user guide describes it as follows: “It uses on-device intelligence to predict when you’ll need extra battery power based on your recent usage patterns, then makes performance adjustments to help your battery last longer.”

Which iPhone models can use Adaptive Power?

The feature uses AI to monitor and choose when its power-saving measures should be activated, so that means only phones compatible with Apple Intelligence get the feature. These are the models that have the option:

• iPhone 17
• iPhone 17 Pro and iPhone 17 Pro Max
• iPhone Air
• iPhone 16 and iPhone 16 Plus
• iPhone 16 Pro and iPhone 16 Pro Max
• iPhone 16e
• iPhone 15 Pro and iPhone 15 Pro Max

Although some iPad and Mac models support Apple Intelligence, the feature is only available on iPhones.

How to turn Adaptive Power on

On the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max and iPhone Air, Adaptive Power is on by default. For other models, you must opt in to use it. In iOS 26, you’ll find the Adaptive Power toggle in Settings > Battery > Power Mode. If you want to be alerted when the feature is active, turn on the Adaptive Power Notifications option.

Adaptive Power sounds like an outgrowth of Gaming Mode, introduced in iOS 18, which routes all available processing and graphics power to the frontmost app and pauses other processes in order to deliver the best experience possible — at the notable expense of battery life.

What does this mean for your charging habits?

Although we all want as much battery life as possible all the time, judging by the description, it sounds as if Adaptive Power’s optimizations will not always be active, even if you leave the feature on. “When your battery usage is higher than usual” could include a limited number of situations. Still, considering that according to a CNET survey, 61% of people upgrade their phones because of battery life, a feature such as Adaptive Power could extend the longevity of their phones just by updating to iOS 26.

I also wonder whether slightly adjusting display brightness could be disruptive, but in my experience so far, it hasn’t been noticeable. Because the feature also selectively de-prioritizes processing tasks, the outward effects will likely be minimal.

We’ll get a better idea about how well Adaptive Power works as more people adopt iOS 26 and start buying new iPhone models. Also, remember that shortly after installing a major software update, it’s common to experience worse battery life as the system optimizes data in the background; Apple went so far as to remind customers that it’s a temporary side effect.

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.
