iPhone 17 Pro Named Fastest-Charging Smartphone

Apple's iPhone 17 Pro has been named the fastest-charging phone overall in a new CNET lab test covering 33 smartphones, with Samsung's Galaxy S26 Ultra taking the top spot for wired charging speed.


To determine the rankings, CNET's lab team ran each phone through a 30-minute wired charging test starting at 10% battery or less, using the phone's included cable and a wall charger rated at or above the device's maximum supported speed. Phones that support wireless charging went through a matching 30-minute wireless test using a Qi (7.5W), Qi2 (15W), or Qi2.2 (25W) charger matched to the phone's peak supported speed. CNET then averaged the wired and wireless results into an overall charging score.

The ‌iPhone 17 Pro‌'s win in the overall category is partly a function of its relatively compact 4,252mAh battery, which is smaller than the 5,000mAh or larger capacities common among competing flagships. With less capacity to fill, the 17 Pro charges faster in absolute terms, and it supports both 40-watt wired charging and 25-watt Qi2.2 wireless charging. CNET notes that battery size is just one factor in overall battery life, alongside processor and software efficiency, and in its battery life testing, the ‌iPhone 17 Pro‌ Max came out on top for endurance.

For wired charging, Samsung's Galaxy S26 Ultra took the top spot, adding 76% charge in 30 minutes via its 60-watt wired charging speed, the fastest of any Samsung flagship to date. The ‌iPhone 17 Pro‌ came in second at 74%, tied with Motorola's Moto G Stylus (2025). The OnePlus 15 followed with 72%, while the iPhone 17, ‌iPhone 17 Pro‌ Max, and Samsung Galaxy S25 FE each reached 69%.

Apple's ‌iPhone 17 Pro‌ also claimed the fastest wireless charging result, gaining 55% in 30 minutes. The ‌iPhone 17 Pro‌ Max added 53%, followed by the ‌iPhone 17‌ at 49%, the iPhone Air at 47%, and the Galaxy S26 Ultra at 39%. CNET again attributes the 17 Pro's edge over the 17 Pro Max largely to its smaller battery, since both devices share the same A19 Pro chip and software.

Across all brands tested, Apple had the most consistent fast-charging performance by a considerable margin, averaging 54.6% across the four ‌iPhone 17‌ models and the ‌iPhone Air‌. Samsung's nine-phone average came in at 38.5%, with the Galaxy S26 Ultra as its strongest performer and the Galaxy Z Fold 7 as its weakest at 29%.

Silicon-carbon batteries, which use a silicon-based anode rather than graphite to enable higher capacities and faster charge rates, appeared among several of the top performers. The OnePlus 15, for example, recharged 72% of its 7,300mAh silicon-carbon battery in 30 minutes using a proprietary 80-watt charger. Silicon-carbon phones in the U.S. remain limited to OnePlus, RedMagic, and Poco. Apple, Samsung, and Google have not yet adopted the technology.

The MacRumors Show: Gemini Announcements and Apple Watch Series 12 Rumors

On this week's episode of The MacRumors Show, we discuss Google's latest wave of announcements for Android and Gemini, the newly announced Fitbit Air, and Apple Watch Series 12 rumors.


The centerpiece of Google's announcements this week was Gemini Intelligence, Google's new umbrella platform for AI across phones, watches, cars, and laptops. Its headline capability is cross-app automation: users can photograph an event flyer and ask Gemini to find tickets on Expedia, or pull up a grocery list and have it build a cart in a shopping app. A companion feature called Create My Widget lets users describe a home screen widget in natural language and have Gemini generate it, drawing from Gmail and Calendar to build a personalized dashboard.

Google also unveiled the Googlebook, a new laptop category designed from the ground up around Gemini with partners including Acer, Asus, Dell, HP, and Lenovo arriving this fall. Gemini in Chrome for Android gained an agentic browsing layer rolling out end of June, and Android Auto received AI-generated contextual replies and DoorDash voice ordering. A Meta partnership brings Ultra HDR, native stabilization, and night mode to Instagram on Android flagship devices.

In January, Apple and Google announced a partnership under which Gemini would power the next generation of Apple Foundation Models, including a more personalized Siri expected this year. Apple's equivalent cross-app ‌Siri‌ actions were announced at WWDC 2024 but have not yet shipped; Gemini Intelligence is rolling out this summer using the same underlying technology.

Google also unveiled the Fitbit Air this week, a screenless fitness tracker priced at $99 that ships on May 26. The device weighs just 12 grams with the band and tracks heart rate, AFib, HRV, SpO2, and sleep stages in a small pill-shaped design with no display, no buttons, and no notifications. Battery life lasts for seven days, with a five-minute fast charge delivering a full day of use. A Stephen Curry Special Edition is priced at $129, with core tracking free and Google Health Premium adding an AI Coach for $9.99 per month after a three-month trial.

The launch accompanies a broader rebrand. The Fitbit app becomes Google Health on May 19, with Google Fit folded in, Apple Health data supported on iOS, and APIs for Garmin, Whoop, and Oura. Bloomberg's Mark Gurman reported earlier this year that Apple has scaled back a comparable Health+ coaching service, with the feature now unlikely to launch. The Apple Watch SE starts at $249 and requires daily charging, and the Fitbit Air's $99 price with no mandatory subscription addresses a segment Apple does not cover.

We also discuss the Apple Watch Series 12, which is shaping up to be an incremental upgrade. Bloomberg's Mark Gurman said in March that he does not expect any major design changes, and a significant redesign is now not expected until 2028.

The leaker known as "Instant Digital" said this week that Touch ID, which appeared in leaked Apple code last year, has been deprioritized in favor of battery life improvements. DigiTimes previously reported on an eight-sensor array on the back of at least one 2026 model, though blood pressure monitoring is said to be further out. A new chip is expected, with leaked code indicating a meaningful upgrade from the S10 used across the last three series. watchOS 27 will be previewed at WWDC on June 8.

Spotify to Adopt Apple's Technology for Video Podcasts

Spotify today announced plans to adopt Apple's HTTP Live Streaming (HLS) technology for video podcasts, a move that will allow creators to distribute video shows across both platforms without changing their existing setup.


Apple introduced an enhanced HLS-based video podcast experience for the iPhone, iPad, Apple Vision Pro, and the web at the end of March. The upgrade significantly improves how video shows are delivered and consumed within Apple Podcasts, but Mac and Apple TV support is not yet available.

Spotify says its Spotify for Creators and Megaphone platforms will support Apple's HLS video technology later this year, describing the move as "a major step toward truly platform-agnostic video distribution." The company says it is "actively working on this integration in coordination with Apple" and will share timeline details in the near future.

This will enable Spotify-hosted creators to distribute their video podcast content across platforms, reaching audiences on both Spotify and Apple Podcasts without changing their existing setup.


Monetization will carry over alongside distribution. Spotify says it plans to support "monetization for video content on ‌Apple Podcasts‌ so creators don't have to choose between audience reach and revenue," with further details on how that will work across platforms to follow.

The company noted that video shows must be uploaded directly to Spotify rather than distributed via RSS, which the company says is necessary to enable engagement-based monetization, real-time analytics, and other Spotify-first features. RSS distribution to other platforms, including ‌Apple Podcasts‌, remains unchanged.

Separately, Spotify also announced that several podcast hosting providers are now live with video support through the Spotify Distribution API. Libsyn, Podigee, Audioboom, Audiomeans, and Podspace have all completed integration, allowing creators on those platforms to distribute video content directly to Spotify and monetize eligible content through the Spotify Partner Program. Additional partner integrations are said to be in progress.
