Apple Watch Series 11 (46 mm, aluminum, GPS, space gray, 2025)

Among the 12 press releases of the “base” Apple Watch models (original Apple Watch through the Series 11), 7 of the 12 have mentioned health and/or fitness features in the headline (or subhead). The Apple Watch Series 11 press release leads with “groundbreaking health insights” and specified hypertension notifications and sleep score as its primary new features along with battery improvements and a more scratch-resistant display.

Stan Ng, Apple’s vice president of Apple Watch and Health Product Marketing, said in the press release that “Apple Watch is the world’s most popular watch, using advanced sensing capabilities to empower millions of people around the world to better understand their health simply by wearing it, while also serving as a fitness coach, message center, mobile wallet, and beautiful timepiece.” He added that the “Apple Watch Series 11 is an indispensable companion that supports users’ health, fitness, safety, and connectivity throughout the day and night.”

The durability of the screen is described in more detail, noting that it is “Made from a unique Ion-X (ion-exchanged strengthened) glass…treated with a breakthrough Apple-designed ceramic coating that bonds to the glass at an atomic level through a physical vapor deposition process, significantly hardening the surface.”

The Apple Watch Series 11 was released with watchOS 26, using the Liquid Glass design also available on all Apple devices as of late 2025. Some of the new features added:

  • 2 new watch faces (Flow and Exactograph)
  • A new one-handed wrist flick gesture to easily dismiss notifications
  • Live Translation in Messages with Apple Intelligence
  • A Watch version of the Notes app (finally!!)

The Aluminum case options for Apple Watch Series 11 were available in Rose Gold, Silver, Jet Black, and a new Space Gray option. Titanium case options included Gold, Natural, and Slate.

The 46 mm model measured 46mm x 39 mm and was 9.7 mm thick. The aluminum/GPS model weighed 37.8 grams.

The screen was 416 x 496 pixels at 326 pixels per inch with an always‑On Retina display with wide‑angle OLEDs. It could display up to 2000 nits peak brightness down to 1 nit minimum brightness.

The Series 11 had an impressive list of sensors:

  • Electrical heart sensor
  • Third‑generation optical heart sensor
  • Blood oxygen sensor
  • Temperature sensor
  • Compass
  • Always‑on altimeter
  • High‑g accelerometer
  • High dynamic range gyroscope
  • Ambient light sensor
  • Depth gauge to 6 meters
  • Water temperature sensor

Connectivity options included support for 2.4GHz and 5GHz Wi-Fi networks with Wi-Fi 4 (802.11n); Bluetooth 5.3; GPS systems including L1, GLONASS, Galileo, QZSS, and BeiDou. It used a second-generation Ultra Wideband chip.

iPad (A16) (Generation 11, 11-inch, Wi-Fi, 128GB, Yellow, 2025)

On March 4, 2025, when Apple introduced the iPad Air with the M3 chip, they also announced the iPad Generation 11 with an A16 chip. The entire press release for this iPad device release amounted to one paragraph:

“Apple today also updated iPad with double the starting storage and the A16 chip, bringing even more value to customers. The A16 chip provides a jump in performance for everyday tasks and experiences in iPadOS, while still providing all-day battery life. Compared to the previous generation, the updated iPad with A16 is nearly 30 percent faster. In fact, compared to iPad with A13 Bionic, users will see up to a 50 percent improvement in overall performance, and A16 makes the updated iPad up to 6x faster than the best-selling Android tablet.”

This iPad update was released soon after the announcement of Apple Intelligence. While Apple was touting Apple Intelligence and updating its devices to take advantage of the new features, the iPad Generation 11 was given a chip that did not allow Apple Intelligence. While this updated iPad is faster than the previous Generation 10 model, it does not meet the minimum specification of the A17 Pro chip to allow Apple Intelligence compatibility. Apple provided no explanation for this omission.

One notable upgrade was in storage on the A16 iPad. The iPad Generation 11 doubled its base storage from 64 to 128GB and was also available in 256 and 512GB configurations. 

Except for the A16 chip and upgraded storage, this iPad was nearly identical to the iPad Generation 10. 

The iPad Generation 11 measured 9.79 x 7.07 inches, and was 0.28 inch thick. It weighed 1.05 pounds (Wi-Fi model). It had stereo speakers, a front camera and microphone centered on the “long”landscape” (long) side to enhance the FaceTime experience, and included both USB-C and a Smart Connector.

Its Liquid Retina display was 2360 x 1640 pixels at 264 ppi and delivered up to 500 nits brightness. It supported the Apple Pencil (USB-C) and also the Apple Pencil Generation 1 (although clumsily since the original Apple Pencil used a Lightning connector for charging). 

The back camera was 12MP with digital zoom up to 5x supporting Smart HDR 4, geotagging, auto image stabilization, and burst mode. It could capture video up to 4K. The similar front camera was also 12MP and supported Center Stage in Landscape mode. It supported Smart HDR 4, but only could record 1080p HD video. 

The iPad Generation 11 had 5 sensors, including Touch ID, 3‐axis gyro, accelerometer, barometer, and an ambient light sensor.

iPad (Generation 2, Wi-Fi, 32 GB, white, 2011)

The iPad 2 represented a major update to the original iPad by allowing the iPad to begin its move from a content-consumption device to a content-creation device, mostly due to the addition of front and back cameras. Apple’s press release led with its subhead, “All New Design is Thinner, Lighter & Faster with FaceTime, Smart Covers & 10 Hour Battery.”

Like the original iPad, the iPad 2 was described as a “magical device for browsing the web, reading and sending email, enjoying photos, watching videos, listening to music, playing games, reading ebooks and much more.” The iPad 2 added “two cameras, a front-facing VGA camera for FaceTime and Photo Booth, and a rear-facing camera that captures 720p HD video, bringing the innovative FaceTime feature to iPad users for the first time.”

The iPad 2 had a silver aluminum back and was available with a white or black front. This example is white.

The iPad 2 had a 9.7-inch glossy LED backlit display (1024×768 at 132 ppi) and could run both iPhone and iPad-specific apps. It shipped with the A5 processor with storage options including 16, 32, or 64 GB. In addition to its front and rear cameras, it had 802.11a/b/g/n Wi-Fi support, an accelerometer, a three-axis gyroscope, an ambient light sensor, digital compass, a speaker and a built-in microphone. The iPad 2 was 33% thinner than the original iPad and weighed 1.33 pounds.

The iPad 2 was also released with the Smart Cover. The Smart Cover used magnets to attach and, when closed, automatically put the iPad 2 into Sleep mode, and would wake the iPad when opened.

AirPods 4 (2024)

Beginning in 2024 Apple began offering the entry-level AirPods 4 product in two versions: AirPods 4 and AirPods 4 with Active Noise Cancellation. These AirPods 4 are the “base” model without the additional features.

As Apple often mentions, “AirPods 4 are the best headphones Apple has ever created.” The updated headphones offer “open-ear design, setting an entirely new benchmark for fit and comfort.”

Apple improved the fit and comfort of these AirPods:

“The new design is built with an unparalleled data set that uses advanced modeling tools, like 3D photogrammetry and laser topography, to precisely map and analyze thousands of ear shapes and over 50 million individual data points in total. This process helped refine the design to deliver the most comfortable AirPods ever with one shape that naturally fits even more users around the world.”

AirPods 4 offer the following core technologies:

  • Custom high-excursion Apple driver
  • Custom high dynamic range amplifier
  • Voice Isolation2
  • Personalized Spatial Audio with dynamic head tracking3
  • Adaptive EQ
  • Vent system for pressure equalization

The AirPods 4 with Active Noise Cancellation add 4 features, including Active Noise Cancellation, Adaptive Audio, Transparency mode, and Conversation Awareness. These additional features also allow this model to use Live Translation for communicating across languages.

AirPods 4 are powered by Apple’s H2 headphone chip. Built-in sensors include:

  • Dual beamforming microphones
  • Inward-facing microphone
  • Optical in-ear sensor
  • Motion-detecting accelerometer
  • Speech-detecting accelerometer
  • Force sensor

These sensors offer many new features not available in previous “base” AirPods models:

“With the H2 chip, AirPods 4 unlock intelligent audio experiences only Apple silicon can deliver, such as Voice Isolation, enabling clearer call quality no matter the environmental conditions, and Siri Interactions, allowing users to simply nod their head yes or gently shake their head no to respond to Siri announcements. For even more control, AirPods 4 also feature a new force sensor on the stem to play or pause media and mute or end calls with a quick press.”

Each AirPod 4 is 1.19 inches (30.2 mm) x 0.72 inch (18.3 mm) and 0.71 inch (18.1 mm) deep. Each weighs 0.15 ounce (4.3 grams). The AirPods 4 case measures 1.82 inches (46.2 mm) x 1.97 inches (50.1 mm) and is 0.83 inch (21.2 mm) deep. The case weighs 1.14 ounces (32.3 grams).

The base AirPods 4 allows only USB-C connector charging, while the AirPods 4 with Active Noise Cancellation adds Apple Watch or Qi‑certified charging. AirPods 4 allow up to 5 hours of listening time on a single charge, however, 5 minutes of charging provides around 1 hour of listening time.

AirPods 4 connect using Bluetooth 5.3.

iPhone 14 Pro (Deep Purple, 2022)

The iPhone 14 Pro was announced on September 7, 2022; began pre-orders on Friday, September 9, 2022; and was available beginning Friday, September 16, 2022. Apple’s website led with the following description of the iPhone 14 Pro:

“A magical new way to interact with iPhone. Groundbreaking safety features designed to save lives. An innovative 48MP camera for mind-blowing detail. All powered by the ultimate smartphone chip.”

The primary new technologies used in the iPhone 14 Pro included: “Always-On display, the first-ever 48MP camera on iPhone, Crash Detection, Emergency SOS via satellite, and an innovative new way to receive notifications and activities with the Dynamic Island.”

The four colors available at release were deep purple, silver, gold, and space black. The iPhone 14 Pro had a 6.1-inch “Super Retina XDR display with ProMotion” with an Always-On display (for the first time on an iPhone) that used a 1Hz refresh rate with power-efficient technologies. In practice, the Always-On display faded to a dim/dark version of the Wallpaper and allowed the time and up to four widgets to show (a widget above the time and up to 3 below the time). Other “Live Activities” showed in the bottom two-thirds of the Lock screen, including alerts and play/pause options for media.

The iPhone 14 Pro also delivered “the highest outdoor peak brightness in a smartphone: up to 2000 nits, which is twice as bright as iPhone 13 Pro.”

The Dynamic Island was also introduced in the iPhone 14 Pro. The design of this iPhone removed the “notch” that had been used since the iPhone X and moved the functions slightly lower into a pill shape. Apple described the Dynamic Island system as one “that blends the line between hardware and software, adapting in real time to show important alerts, notifications, and activities. With the introduction of the Dynamic Island, the TrueDepth camera has been redesigned to take up less of the display area.”

Apple continued, “Without impeding content on the screen, the Dynamic Island maintains an active state to allow users easier access to controls with a simple tap-and-hold. Ongoing background activities like Maps, Music, or a timer remain visible and interactive, and third-party apps in iOS 16 that provide information like sports scores and ride-sharing with Live Activities can take advantage of the Dynamic Island.”

The iPhone 14 Pro camera system added a 2x camera (in addition to the 0.5x, 1x, and 3x options on the iPhone 13 Pro). The iPhone 14 Pro also offered a new “48MP Main camera with a quad-pixel sensor that adapts to the photo being captured, and features second-generation sensor-shift optical image stabilization.”

Other new camera features included a front TrueDepth camera with an ƒ/1.9 aperture for better low-light photos and video, adaptive True Tone flash with an array of nine LEDs, and Action mode for “incredibly smooth-looking video that adjusts to significant shakes, motion, and vibrations, even when video is being captured.”

All iPhone 14 models added Crash Detection that used a variety of built-in sensors (dual-core accelerometer, gyroscope, barometer, GPS, and microphone) to “detect a severe car crash and automatically dial emergency services when a user is unconscious or unable to reach their iPhone.” Additionally, Emergency SOS via satellite was added, “which combines custom components…to allow antennas to connect directly to a satellite, enabling messaging with emergency services when outside of cellular or Wi-Fi coverage.”

The iPhone 14 Pro models are powered by the A16 Bionic chip that includes two high-performance cores and four high-efficiency cores, an accelerated 5-core GPU with 50% more memory bandwidth, and a new 16-core Neural Engine capable of nearly 17 trillion operations per second.

Many of the new features of the iPhone 14 Pro were enabled by iOS 16, released along with the entire iPhone 14 line.

This iPhone 14 Pro example is Deep Purple.
