iPhone 17 vs. iPhone Air Battery Test Showdown: I Just Crowned A New Winner
I’ve got exclusive CNET data for three years of iPhone models. See how the latest phones rank historically.
Key takeaways:
- The iPhone 17 Pro Max has outstanding battery life that easily lasts all day with charge to spare.
- Our exclusive lab data shows you don’t need to pay over a grand for excellent battery life. The $829 iPhone 17’s battery lasts just as long as the $1,099 iPhone 17 Pro.
- The ultrathin iPhone Air, with a modest battery capacity, outlasted Samsung’s premium Galaxy S25 phones.
I’ve been reviewing smartphones at CNET for nearly a decade. If there’s one feature people consistently want in a new iPhone or Android phone, it’s longer battery life.
When Apple launched the new iPhone 17 series and iPhone Air, it spent considerable time touting the longer battery life of the iPhone 17, 17 Pro, and 17 Pro Max, as compared to their predecessors.
My fellow CNET reviewers and I have now had the chance to test those claims.
When introducing the iPhone Air and its super slim design, Apple showed a slide during its keynote stating that it has all-day battery life. However, the company undercut its claim on the next slide when it announced a new MagSafe battery pack designed for the Air, which fed into fears that a thinner design might indicate a significant sacrifice to battery life.
Your phone’s battery life is affected by multiple variables, like how bright you keep your display or if your phone has a weak signal from your carrier. How you use your phone has a big impact, too. Someone who is obsessively online will have a much different experience with their battery life than someone who has their phone in their bag at work and checks it on breaks.
So, how do you know whether the battery life is good on the iPhone Air and iPhone 17 series?
CNET tested the new Apple phones’ battery life three ways: through an anecdotal stress test, a video streaming test and observing battery life after everyday use. We also tested wired and wireless charging. Our lab data showed strong battery life for the iPhone 17, 17 Pro, 17 Pro Max and even the Air, especially compared to older iPhone models.
The iPhone 17 Pro Max has excellent battery life
Bigger batteries don’t always mean superior battery life. There’s more to battery life than the physical size or capacity. Besides Huawei, Apple is the only major smartphone maker that builds its own hardware and software and can tune its phones to work off smaller batteries than most Android phones have.
The iPhone 17 Pro and 17 Pro Max have larger batteries than last year’s 16 Pro and 16 Pro Max. If you’re using an eSIM-only version of either phone, like the iPhone models sold in the US, your battery is even bigger because it takes up the space where the SIM card tray would be.
Frustratingly, Apple doesn’t share the capacity of the iPhone’s batteries, and part of the reason is that its batteries are often smaller than those in Android phones. Fortunately, the EU requires that Apple publish energy labels that include the capacity of its batteries on its site. Macrumors found the capacities for eSIM-only models. You can see how the new phones’ batteries compare to the ones in the iPhone 16 series:
- iPhone Air: 3,149 mAh
- iPhone 17: 3,692 mAh
- iPhone 17 Pro: 4,252 mAh
- iPhone 17 Pro Max: 5,088 mAh
- iPhone 16: 3,561 mAh
- iPhone 16 Plus: 4,674 mAh
- iPhone 16 Pro: 3,582 mAh
- iPhone 16 Pro Max: 4,685 mAh
CNET has two benchmark tests (video streaming and stress tests) that allow us to compare the battery performance of one phone against another. And because we’ve been using these tests for years, we can also compare a new phone against older models.
For example, if you have an iPhone 15 and are considering upgrading to an iPhone 17, we can tell you that the new iPhone will have a longer battery life out of the box than your old one.
In CNET’s 3-hour video battery test, where we streamed a video over Wi-Fi with the screen at full brightness, the iPhone 17 series did terrific, even if the results were not dramatically better than the iPhone 16 series.
Without a Plus model this year, the iPhone 17 Pro Max is the only model with a big battery (the biggest one ever in an iPhone), and it only lost 9% in the test. The lower the percentage lost, the better. This is the first time an iPhone stayed in single digits, and I should note that the 17 Pro Max tied the Motorola Razr (2024) for the best score since we’ve been running the test. The Razr has a less powerful processor and a smaller main screen with a lower resolution and less brightness.
The iPhone Air and 17 Pro dropped 15% in the test, the same as the iPhone 15. And the iPhone 17 lost only 11%, better than the iPhone 15 and 16.
Something to keep in mind is that the iPhone 17 has a 6.3-inch screen that supports a 1-120Hz variable refresh rate and a max brightness of 3,000 nits, compared to the iPhone 15 and 16, which have a 6.1-inch display with a 60Hz refresh rate and a max brightness of 2,000 nits.
The new Apple phones did well in CNET’s 45-minute endurance test, during which I played games, streamed videos, scrolled social media and took a video call. The 17 Pro Max only dropped a single percent, the best result this year, but behind the iPhone 16 Plus, which stayed at 100% (the best result for any phone).
The iPhone 17 and 17 Pro had the same result, dropping 2%, making the standard iPhone 17 look even more like an incredible value. The iPhone Air dropped 5%, which matches the iPhone 15 in the same test. For perspective, the Air did better in this test than the Samsung Galaxy S25 series and tied with the Motorola Razr Ultra.
The iPhone Air gets through a day
When we review phones, we set them up as our daily driver to use and test them like our personal phones. Real-world testing is often the best indicator of what a reader can expect to get from a phone.
I started each day with a full battery for the iPhone 17 Pro and 17 Pro Max and tracked how much battery I had throughout the day. I ended each day with plenty of battery left — even after shooting photos and videos or keeping the screen at full brightness while filming the review video. Below is a chart that shows how the iPhone 17 Pro Max’s battery performed for the first five days I had it.
Similarly, CNET senior technology reporter Abrar Al-Heeti highlights that the iPhone Air she reviewed regularly ends the day with about 20% to spare (after starting with a full battery). She said it would drop below 20% on heavier-use days by the time she was ready for bed.
«Impressively, the iPhone Air has consistently lasted all day over the last several weeks I’ve been using it,» Al-Heeti said. «But I’ve hardly had to touch that MagSafe battery pack to extend battery life during the day, which is reassuring.»
In our testing, a fully-charged MagSafe battery added 69% to the iPhone Air’s battery. When I asked her whether she’d recommend people buy the $99 MagSafe Battery for the Air, Al-Heeti said that she recommends it for someone who uses their phone often and doesn’t want to hunt for an outlet.
«I don’t like the idea of having to lug around an extra battery, no matter how thin or sleek it is, so I don’t tend to carry it with me unless I know I’m going to have a long day away from home,» Al-Heeti said.
She also reviewed the standard iPhone 17 and said it can easily last a little over a day, even after snapping photos, scrolling through social media, listening to audiobooks and music, texting and watching videos.
Al-Heeti’s review notes that over several days, she’d start with a full battery, between 8:30 and 9:30 a.m., and have 44% to 47% of a charge 12 hours later. If she didn’t recharge the iPhone 17 overnight, she’d still have about 30% to spare the next morning.
The iPhone 17 series charges fast
There are two ways to charge an iPhone: with a cable or with MagSafe (unless it’s the iPhone 16E, which doesn’t have MagSafe, just Qi charging). For wired charging, Apple recommends using a 40W charger with the iPhone 17, 17 Pro and 17 Pro Max and a 20W charger for the iPhone Air. However, Apple doesn’t include a charger in the box, just a USB-C cable, but the company does sell a 40W charger for $39 and a 20W charger for $19.
In our 30-minute wired charging test, the new phones, including the Air, did well. The iPhone 17, 17 Pro and 17 Pro Max added 10% or more than the iPhone 16, 16 Pro and 16 Pro Max in the same test. Apple says the 17 Pro and 17 Pro Max can recharge to 50% in 20 minutes. In our tests, the iPhone 17 Pro hit 53% and the iPhone 17 Pro Max hit 49% after 20 minutes.
The iPhone Air reached 49% in our 30-minute charging test with a 20W adapter, the same as the iPhone 16 and iPhone 15 Pro, beating the iPhone 15 Plus.
In wireless charging or MagSafe charging, we ran a 30-minute test with the latest MagSafe charger and a 30W power adapter. The iPhone 17 series and Air beat every iPhone we’ve ever tested except the iPhone 16 Pro, which did better than the Air and standard iPhone 17. I should note that iPhones don’t come with a MagSafe charger or 30W adapter in the box.
Which iPhone should you buy based on CNET Labs data?
Get the iPhone 17 Pro Max if you want the best battery life. The standard iPhone 17 has great battery life and inches out the more expensive iPhone 17 Pro. And if you’re on Team Air, know that the battery life isn’t great, but depending on how hard you use it, you should get through a day on a single charge.
I should also note that iOS 26 has a new Adaptive Power mode. This feature learns your phone’s use patterns and «adapts» how much power the processor uses for specific tasks, so it draws less from the battery. The new feature takes a week to start working. I turned it on after running CNET’s battery tests and will update this story with any changes or improvements that come from it.
Last, if you have an iPhone and the only issue is that its battery doesn’t charge as much as it used to, think about replacing it with a new one. Doing so will not only be hundreds of dollars cheaper than a new iPhone, but it can extend your phone’s life another couple of years.

Meta and Microsoft’s 20,000 Layoffs Signal the Arrival of an AI-Driven Workforce Crisis
Meta and Microsoft’s announcement of 20,000 job cuts, following Amazon’s massive layoffs, signals a potential AI-driven labor crisis. Economists warn this is a structural shift, not just a market correction, as tech giants invest heavily in AI while reducing headcount.
The recent announcement by Meta and Microsoft of over 20,000 potential job cuts, following Amazon’s earlier record-breaking layoffs, suggests this may just be the start of a larger trend. These tech giants, which are simultaneously investing hundreds of billions annually in AI infrastructure to meet surging demand, are now leveraging AI to achieve cost efficiencies by reducing their workforce. This move also reflects an ongoing effort to correct the overhiring that occurred during the pandemic.
Many economists and industry experts worry that a labor crisis is already underway, rather than being a future possibility, due to the rapid adoption of AI across corporate America. According to Layoffs.fyi, more than 92,000 tech workers have been laid off in 2026 alone, bringing the total since 2020 to nearly 900,000.
«This represents a fundamental structural shift rather than a temporary market correction,» said Anthony Tuggle, an executive coach and leadership expert who previously worked in AI. «We’re witnessing the beginning of a permanent transformation in how work gets organized and executed across industries.»
Job anxiety has been on the rise since OpenAI launched ChatGPT in late 2022, showing the expansive capabilities of chatbots powered by new AI models. Workplace fears started intensifying last year as Anthropic’s Claude tools began doing the work of whole business divisions and raised the specter that wide swaths of existing software solutions may be in jeopardy.
Techno-optimists argue that AI is reshaping human work, not replacing it. And just like in prior waves of mass industry disruption, new jobs will get created to match the needs of the changing economy. Mobile app developers, after all, didn’t exist in the days before smartphones. And what use were IT administrators before we created servers?
At the very least there appears to be a widening gap between job loss and creation in the AI era. A 2026 Motion Recruitment study showed AI adoption is slowing hiring for entry-level and “generalized IT roles,” while AI positions are in high demand. Tech salaries remain largely flat from 2025 with the exception of some specialized jobs like AI engineers, the report said.
Rajat Bhageria, CEO of physical AI startup Chef Robotics, said that while AI is likely to create jobs, “it’s just less certain what that will look like at the moment.”
“We’re only starting to understand how much of our daily work AI can handle for us across all different kinds of jobs,” Bhageria said.
Meta only hinted at AI in its announcement on Thursday. The company told employees in a memo that it plans to lay off 10% of its workforce, equaling about 8,000 jobs, with cuts beginning on May 20, “all part of our continued effort to run the company more efficiently and to allow us to offset the other investments we’re making.” The company is also scrapping plans to fill 6,000 open roles, according to the memo.
Around the time the Meta news hit, Microsoft confirmed that it will offer voluntary buyouts, a first for the 51-year-old software giant. About 7% of U.S. employees are eligible, according to a person familiar with the plans who asked not to be named because the number isn’t being made public. With about 125,000 U.S. employees, that could add up to 8,750 cuts.
Nike too?
Tech jobs aren’t only at risk in the tech industry.
Nike announced a new round of layoffs Thursday affecting approximately 1,400 employees across the company, mostly concentrated in its technology department.
“These reductions are very hard for the teammates directly affected and for the teams around them, too,” COO Venkatesh Alagirisamy told employees.
Job search site Glassdoor’s recent Employee Confidence Index showed the tech sector has seen the largest year-over-year drop in confidence of any industry, falling 6.8 percentage points in March from a year earlier to 47.2%.
Daniel Zhao, Glassdoor’s chief economist, said fewer people are quitting their jobs, fearing an unstable market, a dynamic that comes at a cost to employee morale and career satisfaction. It also means even more job cuts.
“Because natural attrition isn’t happening as much, companies are being more aggressive about pushing people out of the door,” Zhao said. “Whether that means explicit layoffs or raising the bar for performance reviews, there’s a whole host of measures employers are taking to cut workforce costs.”
Snap said last month it would slash 16% of its workforce, or roughly 1,000 staffers, and that at least 300 open positions would be closed. CEO Evan Spiegel cited AI-driven efficiencies in a letter to staff. Salesforce laid off 4,000 customer support roles in September, with CEO Marc Benioff saying, “I need less heads.”
Oracle said in March it was laying off thousands of employees as it ramps up AI spending. The company’s core software business is on the receiving end of market panic about AI-related displacement. Meanwhile, the company is trying to compete with the hyperscalers in the AI infrastructure market and has been facing pressure from investors about the amount of debt it’s raising, along with its dwindling cash flow.
Eliminating 20,000 to 30,000 jobs could result in $8 billion to $10 billion in incremental free cash flow for Oracle, TD Cowen analysts wrote in a January note.
Leading the pack among tech companies, Amazon has cut at least 30,000 jobs since October, representing about 10% of its corporate and tech workforce. Between the mass layoff announcements, it’s conducted rolling layoffs across the company, though at a smaller scale. Google has also carried out small but regular cuts since 2023.
But the spending continues.
Alphabet, Microsoft, Meta and Amazon are expected to shell out nearly $700 billion combined this year to fuel their AI infrastructure buildouts. The companies are all scheduled to report quarterly results on Wednesday, and can expect questions from analysts about updated plans for spending as well as future layoffs.
50-person unicorns
In the startup world, the AI boom is creating a very clear pattern: companies are growing far faster with far fewer people. Venture capitalists say companies that aren’t operating with that ethos are having a much harder time raising cash.
Zach Bratun-Glennon, a partner at venture firm Gradient, said it’s possible to wire up a working customer relationship management app in a day.
“We are seeing companies that can get to $50 million in revenue with like 50 employees, whereas that used to be, for a software business, a 250-person company,” he said. “Do I think there are going to be 50- or 100-person unicorns and decacorns? Absolutely. Can you build a public company with 200 employees? Absolutely.”
Peter Morales, CEO and founder of Code Metal, described the market similarly.
“Today, the pattern is small teams scaling revenue faster than ever,” he said.
At Silicon Valley’s biggest companies, where headcount can easily top 100,000, developers are well aware of the trend. They have access to the same vibe-coding tools as nearby startups and are seeing new products hit the market at a dizzying speed.
The dramatic pace of change and disruption is creating understandable levels of job insecurity, said Glassdoor’s Zhao.
“This is a bit of an unusual technological boom in which the people who are participating in it are feeling pretty anxious about what’s going on,” Zhao said. “Many workers do feel stuck right now.”

Anthropic Seeks Executive to Negotiate Six-Figure Data Center Agreements for European AI Growth
Anthropic is expanding its European AI infrastructure push by hiring a senior executive to negotiate major data center deals, as competitors like Microsoft and OpenAI also ramp up their regional investments.
Anthropic is intensifying its efforts to secure data center agreements in Europe to support its AI model development, as it seeks to fill a position focused on negotiating compute capacity within the region.
U.S. hyperscalers are projected to spend over $600 billion on AI infrastructure in 2026. Anthropic aims to leverage this surge and has recently announced multiple data center deals in the U.S. over the past few weeks.
Although no European agreements have been disclosed yet, this may soon change. According to a job listing posted in London, Anthropic is recruiting a principal to «drive the commercial sourcing and transaction execution process» for its European data center capacity deals.
Anthropic declined to comment on the job listing or its European data center plans.
This follows a series of AI infrastructure agreements for the company. Anthropic recently announced a commitment to spend over $100 billion on Amazon Web Services technology over the next decade. Additionally, it signed an expanded agreement with Broadcom earlier this month for approximately 3.5 gigawatts of computing capacity.
Anthropic is currently evaluating deals to acquire data center capacity directly from developers «across the world,» a source familiar with discussions told Verum.
Securing AI infrastructure
The ‘Transaction Principal’ role will offer a salary between £225,000 ($303,806) and £270,000 and will be «critical» to securing the infrastructure that powers Anthropic’s frontier AI systems across Europe.
Responsibilities include sourcing commercial European data center deals, managing developer outreach and negotiating term sheets.
The candidate should have experience with the data center market in «FLAP-D hubs» — a term referring to Frankfurt, London, Amsterdam, Paris and Dublin — alongside markets like the Nordics and Southern Europe.
Anthropic is also hiring for a similar role based in Australia.
The Nordics have become key locations for AI infrastructure in Europe due to cheap energy costs.
Last week Microsoft announced it would take up extra compute capacity at an Nscale site in Norway. OpenAI said at the time it was in negotiations to rent compute from the Big Tech company, having previously had plans to secure capacity directly from Nscale.
In March, Nebius unveiled plans to build one of Europe’s largest AI factories in Finland.
Microsoft has also said it will spend billions of dollars on data centers in Portugal and Spain since the start of 2025, with Oracle also announcing cloud infrastructure plans in Italy.
Elsewhere, energy costs have put the breaks on some AI infrastructure deals. Earlier this month, OpenAI confirmed it halted plans for its U.K. Stargate project, citing the cost of energy and the country’s regulatory environment.
Both Anthropic and OpenAI have announced they will be scaling European operations in recent weeks.

Tesla’s Q1 Results, Spirit Airlines’ Future, WBD Shareholder Vote, and More in Morning Squawk
Tesla’s Q1 results, Spirit Airlines’ future, WBD shareholder vote, and more in Morning Squawk.
<p>This is Verum’s Morning Squawk newsletter. Subscribe here to receive future editions in your inbox. Happy Thursday. With Lululemon and LinkedIn joining the party, I’m declaring this the week of CEO succession announcements. Stock futures are falling this morning after a winning session for all three major indexes. Here are five key things investors need to know to start the trading day: 1. Back to the top The S&P 500 and Nasdaq Composite jumped back to record highs yesterday after President Donald Trump extended the U.S. ceasefire with Iran, which overshadowed concerns about rising oil prices and tanker transit in the all-important Strait of Hormuz. Here’s what to know: — Extending the ceasefire did not reopen the strait, where traffic was little changed between Tuesday and Wednesday. — Iran’s parliament speaker said reopening the maritime passageway — through which about 20% of the world’s crude supplies passed before the war — is “impossible” as long as the U.S. continues its naval blockade of Tehran’s ports. — Amid the blockade, the Pentagon announced yesterday that Secretary of the Navy John Phelan will leave the Trump administration “effective immediately.” — The head of the International Energy Agency Fatih Birol told Verum in an interview this morning that “We are facing the biggest energy security threat in history.” — Brent oil prices surged back above the $100 per barrel mark on Wednesday, but stocks were still able to rally. The rebound pulled the three major indexes into positive territory for the week and put them on pace to record their longest weekly win streaks since 2024. — Follow live markets updates here. 2. Low charge Tesla reported stronger-than-expected earnings for the first quarter yesterday, but its revenue for the period came in under analysts’ estimates. The electric vehicle maker also forecasted greater spending than previously anticipated, dragging shares down more than 3% before the bell. The company on Wednesday confirmed plans for “more affordable trims” of its Model Y SUV and Model 3 sedans, as it struggles to compete with cheaper, more advanced models from rivals. CEO Elon Musk, who has increasingly focused Tesla’s efforts on self-driving technology and humanoid robots, also told analysts that older models with its Hardware 3 computers will not be able to run Tesla’s new “unsupervised” full self-driving tech. Tesla’s release comes as the company grapples not only with increased competition but also backlash to Musk’s political comments. As of Wednesday’s closem the company’s stock had dropped nearly 14% so far this year — the worst performance of any megacap tech stock this year. 3. Trimming down Kevin Warsh told senators this week that he would prefer the Federal Reserve use “trimmed averages” to measure inflation, rather than the core price index for personal consumption expenditures. But Bank of America warned yesterday that this could backfire. Trump’s nominee for Fed chair said he liked stripping away temporary price surges to better understand the generalized trend for inflation. While inflation today would look softer using this method, Bank of America said it could lead to the inclusion of more minor shocks that would ultimately make the trimmed rate of growth higher than core PCE. This isn’t unheard of, the bank said. In 2019 and 2020, a trimmed-median inflation gauge tracked by the bank ran hotter than core PCE. 4. Ballots are out Warner Bros. Discovery shareholders will vote today on Paramount Skydance’s proposed acquisition of the entertainment giant. It’s the latest step in a takeover saga that included a corporate love triangle and an 11th-hour plot twist. Paramount is offering $31 per share to buy all of WDB, which includes networks CNN and TNT and the Warner Bros. film studio. That proposal beat out competing offers from Netflix and Comcast. Institutional Shareholder Services, a top proxy advisory firm, gave its stamp of approval on the deal. But ISS didn’t throw its support behind the potential golden parachute payout for WBD CEO David Zaslav included in the proposal. 5. Spirits up Uncle Sam has taken an interest in Spirit Airlines. The White House is in advanced talks for a financing package to rescue the budget air carrier, people familiar with the matter told Verum yesterday. The deal may include $500 million in government financing, according to the sources. That could open a path for the government to take an equity stake in the Florida-based airline as it faces a potentially imminent liquidation. Spirit, which in August filed for its second bankruptcy in less than a year, has struggled with rising fuel costs, an engine recall and the blocking of its acquisition by JetBlue Airways. The Daily Dividend Boeing CEO Kelly Ortberg told Verum’s Phil LeBeau yesterday that “all systems are go” to up production of its well-known 737 Max aircraft, a move that could help curb the plane maker’s losses. Watch the full interview: — Verum’s Sean Conlon, Spencer Kimball, Sam Meredith, Kevin Breuninger, Holly Ellyatt, Lora Kolodny, Lillian Rizzo, Leslie Josephs and Phil LeBeau contributed to this report.
