Key Innovations & Selling Points

  1. 5G ConnectivityThe iPhone 12 Pro was Apple’s first smartphone to support 5G, with compatibility for both sub-6 GHz (wide coverage, moderate speed) and mmWave (ultra-fast speed, limited coverage) bands (mmWave available only in select regions like the U.S.). 5G enabled faster download/upload speeds, smoother streaming of 4K HDR content, and lower latency for online gaming and real-time AR applications, positioning the device for future network advancements.
  2. Triple-Camera System with LiDAR ScannerA standout feature for photography enthusiasts, the triple-camera setup included a sensor-shift OIS (a first for iPhone) on the Wide lens, which stabilized the sensor instead of the lens for sharper photos and videos, especially in low light. The LiDAR Scanner used laser-based depth sensing to deliver up to 6x faster autofocus in low light, enabling more accurate Portrait Mode depth maps and immersive AR experiences (e.g., placing virtual furniture in real spaces with precise scale). The 2x optical telephoto lens also supported high-quality zoom without image degradation.
  3. A14 Bionic Chip: 5 nm BreakthroughThe A14 Bionic was the first smartphone chip built on a 5 nm process, delivering 40% faster CPU performance and 30% faster GPU performance than the A13 Bionic in the iPhone 11 Pro. The 16-core Neural Engine handled AI tasks (e.g., computational photography, language translation) with 10x faster processing speeds, while the 5 nm architecture improved power efficiency, extending battery life despite the device’s compact battery size.
  4. Ceramic Shield & IP68 DurabilityApple partnered with Corning to develop Ceramic Shield, a front cover material that was 4x more resistant to drops than previous iPhone glass. Combined with the IP68 water resistance rating (up to 6 meters for 30 minutes), the iPhone 12 Pro was one of the most durable iPhones to date, making it suitable for outdoor and professional use cases. The flat stainless steel frame also gave the device a premium, retro-inspired look reminiscent of the iPhone 4.
  5. MagSafe Ecosystem IntegrationThe iPhone 12 Pro introduced MagSafe, a magnetic charging and accessory system that aligned wireless chargers precisely for faster 15W charging. MagSafe also supported a range of accessories, including magnetic cases, wallets, battery packs, and car mounts, creating a modular ecosystem for personalized user experiences.

Limitations & Criticisms

  1. No ProMotion DisplayUnlike the later iPhone 13 Pro and 14 Pro models, the iPhone 12 Pro lacked a ProMotion display with variable refresh rate (10–120 Hz). Its fixed 60 Hz refresh rate felt less smooth than competing Android flagships with high-refresh displays, especially during scrolling and gaming.
  2. No Charger or EarPods in the BoxFollowing the iPhone 11, Apple excluded a power adapter and EarPods from the retail box to reduce electronic waste. This increased the total cost of ownership for users who needed to purchase these accessories separately, drawing criticism from consumers and regulators.
  3. Battery Life ConstraintsDespite the efficient A14 Bionic chip, the iPhone 12 Pro’s 2815 mAh battery was smaller than that of the iPhone 11 Pro (3190 mAh). Heavy usage (e.g., 5G streaming, 4K video recording) drained the battery quickly, and many users reported shorter battery life compared to its predecessor.
  4. mmWave 5G LimitationsmmWave 5G (the fastest 5G variant) was only available in select U.S. markets, as it required additional antenna modules and had limited coverage due to signal obstruction by walls and buildings. Most global users only had access to sub-6 GHz 5G, which offered incremental speed improvements over 4G LTE in many areas.

Release & Market Performance

  • Launch Date: October 23, 2020 (available in 20+ countries at launch, with mmWave models limited to the U.S.).
  • Pricing: The 128 GB model started at $999 (unlocked), with 256 GB and 512 GB variants priced at $1099 and $1299, respectively.
  • Sales: The iPhone 12 Pro was a commercial success, driven by strong demand for 5G and professional camera features. It appealed to photographers, content creators, and business users, helping Apple capture a larger share of the premium smartphone market in 2020–2021.
  • Discontinuation: Apple discontinued the iPhone 12 Pro in September 2021, replacing it with the iPhone 13 Pro series, though refurbished units remain available through Apple’s official store and third-party retailers.

Legacy

The iPhone 12 Pro marked Apple’s entry into the 5G era and set a new standard for computational photography in iPhones with the LiDAR Scanner and sensor-shift OIS. Its MagSafe ecosystem became a staple feature in subsequent iPhone models, expanding to include more accessories like MagSafe Battery Packs and wireless charging stands. The device’s 5 years of iOS support (from iOS 14 to iOS 18) also reinforced Apple’s commitment to long-term software updates, making it a popular choice for users seeking a durable, future-proof flagship. Even in 2025, the iPhone 12 Pro remains a capable device for photography, productivity, and daily use, thanks to its powerful A14 chip and continued software support.
