iPhone 17 Pro Review: Apple's Vapor Chamber Thermal Management and Other Improvements

HTX Studio

Introduction to iPhone 17 Series [0:00]

• The video begins by introducing the new iPhone 17 models, highlighting major upgrades.
  • The standard iPhone 17 gets a high refresh rate display after four years [Image 49][0:47].
  • The Pro model features a powerful telephoto lens and a new design [Image 51][0:58].
  • A new ultra-thin "iPhone Air" model is introduced [Image 60][1:42].
• The most useful upgrade, according to the reviewer, is the vapor chamber on the Pro model for thermal management.

Design and Display Improvements [0:45]

• iPhone 17 Standard Model:
  • The back design is similar to last year, but with softer colors [Image 48][0:49].
  • The front adopts the Pro's display with a larger size and slimmer bezels, giving it a more refined look.
• iPhone 17 Pro Model:
  • The camera bump is stretched out [Image 54][1:08].
  • The frame and the camera bump area are now metal, extending into the back glass.
    • This design change is said to improve durability against drops, making the back glass less likely to break [Image 57][1:23].
    • The middle glass still allows for wireless charging.
  • The mixed material design (metal and glass) loses the seamless look of pure glass.
  • The titanium frame from the iPhone 15 Pro is replaced with aluminum.
    • The upside is a unibody design that allows for better cooling [Image 56][1:16].
• iPhone Air Model:
  • This is presented as the most eye-catching design due to its ultra-thin profile [Image 60][1:42].
  • It's 5.6mm thick and weighs 165g, with super-slim bezels, making it feel like holding a piece of glass [Image 63][1:50].
  • A dummy model was used for filming due to the limited availability of review units.

Battery Life and Charging Enhancements [2:05]

• Significant Battery Life Improvements:
  • The iPhone 17 Pro improved by 18 percentage points (43% remaining vs. 25%) compared to the iPhone 16 Pro, lasting longer than the regular version [Image 68][2:16].
  • The iPhone Air performed surprisingly well, with only a 6% battery drop after 50 minutes of 4K video streaming, comparable to the iPhone 17's 7% drop [Image 71][2:36].
• Faster Charging Speeds:
  • iPhone 17 and 17 Pro: Stable charging power jumped from 20W to 29W, reducing full charging time by approximately 25 minutes [Image 74][2:57].
  • iPhone 17 Pro Max: Stable charging power increased from 27W to 35W, saving about 30 minutes in charging time.
  • This marks the first significant iPhone charging upgrade in four years.

Screen Technology and Eye Comfort [3:03]

• High Refresh Rate for Standard Models:
  • For the first time, the standard iPhone 17 gets a 120Hz high-refresh-rate ProMotion display, a feature previously exclusive to Pro models since 2021 [Image 87][3:03].
• Ceramic Shield 2 for Enhanced Durability:
  • The iPhone 17 features the second generation of Ceramic Shield, with Apple claiming 3x better scratch resistance [Image 91][4:13].
  • A hardness test demonstrated the iPhone 17's screen could withstand 8.4 Newtons of force before scratching, significantly more than the iPhone 16's 3.3 Newtons [Image 92][4:24].
• Display Pulse Smoothing (PWM) for Eye Comfort:
  • A new accessibility switch called "Display Pulse Smoothing (PWM)" is introduced [Image 95][3:41].
  • This feature allows iPhones to adjust PWM dimming, which traditionally causes flicker for some sensitive users [Image 97][4:00].
  • Enabling PWM smoothing reduces the black areas and enlarges the white areas, making the brightness adjustment appear smoother and closer to real brightness control [Image 101][4:37].

Camera System Upgrades [4:50]

• Front Camera Improvements:
  • It now uses a square sensor, allowing for wider landscape shots even when holding the phone upright [Image 109][5:20].
  • The lens itself is also wider, making it ideal for group selfies [Image 104][4:56].
  • Front camera comparison between iPhone 16 Pro Max and iPhone 17 Pro Max shows improvements [Image 112][5:29].
  • A new "Dual Capture" mode lets users record both the scene and their reaction simultaneously [Image 115][5:46].
    • The two views are merged, meaning the smaller window cannot be removed or repositioned after recording [Image 117][5:58].
• Telephoto Lens on Pro Models:
  • The main and ultra-wide cameras remain similar to the iPhone 16 Pro.
  • The real upgrade is the telephoto lens on the Pro, now a 100mm equivalent with a 48MP sensor [Image 121][6:15].
    • Sample images demonstrate clearer and sharper results, especially in videos and low-light conditions [Image 122][6:25][Image 131][6:47].
    • The larger sensor and more pixels allow for 8x optical-quality zoom via cropping [Image 130][6:39].
• ProRes RAW HQ Video Recording:
  • The system now supports Apple ProRes RAW HQ video recording, offering superior sharpness and editing flexibility [Image 142][7:00].
  • However, a 15-second video can take up to 4GB of storage, making it impractical for daily use [Image 143][7:06].

Performance and Cooling [6:57]

• New A19 and A19 Pro Chips:
  • The iPhone 17 series and iPhone Air use the new A19 chip.
  • The regular iPhone 17 and iPhone Air feature the A19 chip.
  • The iPhone 17 Pro and Pro Max use the A19 Pro chip, which has one extra GPU core [Image 152][7:06].
• Benchmark Scores:
  • CPU scores improved by 8% for the regular iPhone 17 and 10.7% for the iPhone 17 Pro compared to their predecessors.
  • GPU improvements were more significant: 16.5% for the regular iPhone 17 and 24.2% for the iPhone 17 Pro [Image 153][7:17].
  • The iPhone 16 Pro showed an average framerate of 34.8 FPS in Resident Evil: Village, while the iPhone 16 achieved 36.6 FPS [Image 155][7:27].
• Vapor Chamber Cooling System on Pro Models:
  • The iPhone 17 Pro models are the first to incorporate a vapor chamber for cooling [Image 157][7:39].
    • Thermal imaging shows the iPhone 17 Pro Max distributes heat more evenly across the device, resulting in significantly lower overall temperatures compared to the iPhone 16 Pro Max [Image 158][7:55][Image 160][8:10].
    • Better cooling means less brightness throttling in games: iPhone 16 Pro dimmed significantly after a minute of gaming, dropping brightness from 500 nits to 170 nits, while iPhone 17 Pro maintained higher brightness (500 to 400 nits) and experienced much less disruption [Image 162][8:26].
  • For 4K 60fps video recording, the iPhone 17 Pro Max lasted 19 minutes before dimming, compared to 13 minutes for the 16 Pro Max [Image 165][8:47].

iOS 26 and Software Innovations [9:18]

• "Liquid Glass" Design Language:
  • iOS 26 introduces a new "Liquid Glass" design language with rounded icons and dynamic lighting effects [Image 180][9:30].
    • Icons and folders appear more three-dimensional with shifting highlights [Image 183][9:44].
    • Transparent folders bend the wallpaper like light refraction [Image 186][10:04].
  • Initial feedback was mixed due to potential readability issues and a "too glassy" look [Image 188][10:20].
• Enhanced System Animations and Usability:
  • Almost all system animations are bouncier, making the interface feel more responsive.
  • Common actions in Apple apps are now placed at the bottom for easier reach, as seen in Apple Music UI comparison (iOS 18 vs iOS 26) [Image 202][11:15].
  • A full-screen swipe-back gesture is introduced, allowing users to swipe from any part of the screen to go back [Image 205][11:25].
• Call Screening:
  • A new call screening feature allows the iPhone to answer unknown calls, ask for the caller's identity and reason, and provide a live transcript before the user decides to answer [Image 238][12:12].
• Spatial Photo/Video Feature:
  • Almost any photo can be "3D-ified" and used as a lock screen wallpaper, which actually works quite well [Image 190][10:37].
• Seamless Track Switching in Apple Music (AutoMix):
  • AI stitches song endings and intros to create DJ-smooth transitions between tracks [Image 261][13:00].
• Apple Intelligence (AI) - Delayed and Speculative:
  • Apple's promised personalized Siri from iOS 18 [2024] was delayed due to technical challenges [Image 291][16:03].
  • The video speculates on the future of Apple Intelligence and its potential to revolutionize iPhone usage, if successfully integrated. Examples of proposed AI features include: Siri providing flight reminders based on calendar events [Image 254][15:58], assisting with payments by reading screen context [Image 311][17:05], providing contextual navigation and meeting information in CarPlay [Image 321][17:34], and advanced image recognition [Image 331][18:03]. The vision for AI involves deep integration with the OS to contextually assist users [Image 306][18:23].
