When Apple released the iPhone 12 in October 2020, it marked a significant shift in design and technology for the company’s flagship lineup. But for owners of the iPhone 11 Pro — a device widely praised for its camera system and premium build — the question remained: is upgrading to the iPhone 12 truly worthwhile? After all, both phones share many core features, including top-tier processors, triple-camera systems, and high-end displays. This article dives deep into the differences that matter most: performance, camera quality, battery life, display technology, and long-term value.
Design and Build: A Return to Flat Edges
The most immediately noticeable difference between the iPhone 12 and 11 Pro is the design language. The iPhone 11 Pro followed the curved-edge aesthetic introduced with the iPhone X, featuring rounded corners and a sleek, glass-and-stainless-steel profile. In contrast, the iPhone 12 brought back flat aluminum edges reminiscent of the iPhone 5 era, giving it a more modern, minimalist look.
Despite the visual refresh, both devices are built with premium materials. The 11 Pro uses surgical-grade stainless steel, which feels heavier and more luxurious in hand. The iPhone 12 swaps this for aerospace-grade aluminum, making it slightly lighter but less resistant to scratches. Both feature glass backs for wireless charging, though the 12 introduces Ceramic Shield front cover glass, which Apple claims offers four times better drop performance.
Display Technology: OLED Evolution
Both phones use Super Retina XDR OLED displays, a major advantage over LCD models. However, there are subtle but meaningful improvements in the iPhone 12’s screen. It has a peak brightness of 1,200 nits (compared to 800 nits on the 11 Pro), which enhances HDR video playback and improves visibility under direct sunlight.
The resolution is nearly identical — 2532 x 1170 pixels on the 12 versus 2436 x 1125 on the 11 Pro — but the newer panel benefits from improved color accuracy and contrast ratios thanks to tighter integration with iOS 14 and later updates. For media consumers and photographers, this means richer blacks and more vibrant highlights.
One trade-off: the iPhone 12 is slightly larger (6.1 inches) than the 11 Pro (5.8 inches), which may affect one-handed usability for some users. However, the bezels are thinner, so the overall footprint isn’t drastically different.
Performance: A14 Bionic vs A13 — Real-World Impact
Under the hood, the iPhone 12 is powered by Apple’s A14 Bionic chip, the first smartphone processor built on a 5-nanometer process. Compared to the A13 in the 11 Pro, the A14 delivers about 16% faster CPU performance and 8% better GPU efficiency. While these numbers sound modest, they translate into tangible benefits.
- Faster app launches and multitasking responsiveness
- Better sustained performance during intensive tasks like video editing or gaming
- Improved machine learning capabilities for photography and AR applications
In everyday use, the difference may not be dramatic. Apps open quickly on both devices, and neither shows signs of lag. However, the A14’s architectural improvements mean longer software support. Apple typically supports iPhones for five to six years, and the iPhone 12 is likely to receive updates until at least 2027, compared to 2025–2026 for the 11 Pro.

Camera Comparison: Incremental Gains
The camera systems on both phones include dual 12MP rear sensors (wide and ultra-wide) plus a telephoto lens on the 11 Pro. The iPhone 12 retains the same setup but introduces Night mode across all lenses — a feature previously limited to the main sensor on the 11 Pro.
In low-light conditions, the iPhone 12 produces noticeably brighter and cleaner images, particularly on the ultra-wide lens. Smart HDR 3, powered by the A14, also improves dynamic range, preserving more detail in shadows and highlights. Video recording sees a bigger leap: the iPhone 12 supports Dolby Vision HDR at 4K/30fps, allowing for professional-grade video capture straight from your pocket.
| Feature | iPhone 11 Pro | iPhone 12 |
|---|---|---|
| Night Mode (Main) | Yes | Yes |
| Night Mode (Ultra-Wide) | No | Yes |
| Dolby Vision Video | No | Yes (4K/30fps) |
| Sensor Size (Main) | 1/2.55\" | 1/2.55\" |
| Deep Fusion | Yes | Yes (enhanced) |
For casual photographers, the improvements may not justify an upgrade. But for creators who shoot frequently in varied lighting or want to record cinematic video, the iPhone 12 offers measurable advantages.
Battery Life and Charging: Efficiency Over Endurance
Battery capacity hasn’t increased significantly — in fact, the iPhone 12 has a slightly smaller battery (2,815 mAh) than the 11 Pro (3,046 mAh). Yet, thanks to the energy-efficient A14 chip and optimized iOS power management, real-world usage shows comparable endurance.
Both phones last about 17–19 hours of mixed usage, including browsing, messaging, and media playback. The iPhone 12 gains an edge in standby efficiency due to better background task handling. However, it lacks the higher-capacity batteries found in the 11 Pro Max or 12 Pro Max, so heavy users might still find themselves reaching for a charger by late afternoon.
Charging speed remains unchanged: 20W fast charging supported via USB-C to Lightning cable (sold separately), and 15W MagSafe wireless charging introduced with the iPhone 12. The 11 Pro only supports 7.5W Qi wireless charging, making the upgrade appealing for those adopting Apple’s new magnetic ecosystem.
5G Connectivity: The Game Changer?
The most significant hardware addition in the iPhone 12 is 5G support. This enables faster download and upload speeds where networks are available, reducing buffering for streaming and improving cloud-based workflows. However, the practical benefit depends heavily on location and carrier coverage.
In urban areas with mmWave or mid-band 5G, users report near-instantaneous app downloads and smoother live video uploads. But in rural or suburban zones, 5G often reverts to LTE speeds, and the radio can drain the battery up to 20% faster when constantly searching for signal.
Mini Case Study: Sarah’s Upgrade Decision
Sarah, a freelance photographer based in Austin, TX, used her iPhone 11 Pro daily for client work, social media content, and personal photos. By late 2022, she noticed slower performance when editing RAW files in Lightroom and wanted better low-light results.
She upgraded to the iPhone 12 primarily for Night mode on the ultra-wide lens and Dolby Vision video. The ability to shoot high-dynamic-range footage without external gear streamlined her workflow. Though she initially missed the heft of the stainless steel frame, she appreciated the improved screen brightness outdoors and faster app response times. Most importantly, knowing her device would be supported for several more years gave her peace of mind.
For Sarah, the upgrade was justified — not because of radical changes, but due to consistent refinements that added up across her daily routine.
Is the Upgrade Worth It? A Practical Checklist
Before deciding whether to move from the iPhone 11 Pro to the iPhone 12, consider the following checklist:
- ✅ Do you need 5G for faster connectivity in your area?
- ✅ Are you interested in shooting Dolby Vision HDR video?
- ✅ Do you frequently take photos in low light, especially with the ultra-wide lens?
- ✅ Do you value longer software support (iOS updates through 2027)?
- ✅ Are you looking for a lighter, flatter design with improved drop resistance?
- ❌ Are you satisfied with current performance and camera quality?
- ❌ Is budget a constraint? (Used 11 Pro models now offer excellent value.)
If most of your answers are “yes” to the first five and “no” to the last two, the iPhone 12 is a logical next step. Otherwise, sticking with the 11 Pro — or even waiting for a newer model — may make more financial sense.
