Display Comparison

The Galaxy S23 Ultra’s 1274 nits measured brightness is slightly lower than the iPhone 15 Pro’s 1786 nits, but both displays are exceptionally bright and visible outdoors. While Samsung boasts an 'Infinite' contrast ratio, the practical difference is minimal. Both utilize adaptive refresh rate technology, but the iPhone 15 Pro’s ProMotion technology dynamically adjusts up to 120Hz, while Samsung’s is also 120Hz. The iPhone 15 Pro benefits users sensitive to flicker with a higher PWM dimming rate, though specific frequencies aren’t provided in the data. The S23 Ultra’s larger screen size is a boon for media consumption, while the iPhone 15 Pro’s smaller form factor offers greater one-handed usability.

Camera Comparison

Both phones excel in photo and video capture, but approach it differently. The S23 Ultra’s camera system is renowned for its versatility, particularly its impressive zoom capabilities (not detailed in the provided data, but a key feature). The iPhone 15 Pro focuses on delivering cinematic-quality video recording. While sensor sizes aren’t specified, the S23 Ultra’s larger sensor generally captures more light, improving low-light performance. Both devices feature optical image stabilization (OIS). The iPhone 15 Pro’s image processing prioritizes natural colors, while Samsung’s tends towards more vibrant, saturated tones. The absence of detail on specific lens apertures makes a precise comparison difficult, but both offer excellent image quality.

Performance

The Apple A17 Pro, fabricated on a 3nm process, boasts a hexa-core CPU configuration with peak clock speeds of 3.78 GHz. This contrasts with the Samsung Galaxy S23 Ultra’s octa-core Snapdragon 8 Gen 2 (4nm). While the Snapdragon 8 Gen 2 has more cores, the A17 Pro’s architectural advantages and smaller node size translate to superior single-core performance. The A17 Pro’s GPU is also expected to deliver a significant performance uplift, particularly in graphically intensive games. The Snapdragon 8 Gen 2’s 4nm process offers excellent thermal efficiency, potentially mitigating throttling during sustained workloads, a common concern with previous Snapdragon generations. Both devices utilize LPDDR5X RAM, ensuring fast memory access.

Battery Life

The Samsung Galaxy S23 Ultra demonstrates superior battery endurance with an active use score of 13:24h and an endurance rating of 126h, compared to the iPhone 15 Pro’s 12:58h and 86h respectively. While the iPhone 15 Pro supports both MagSafe and Qi2 wireless charging (requiring iOS 17.2), the S23 Ultra’s 45W wired charging (65% in 30 minutes) is significantly faster than the iPhone 15 Pro’s 50% in 30 minutes. Both offer 4.5W reverse wired charging, a niche feature for topping up accessories.

Buying Guide

Buy the Apple iPhone 15 Pro if you need a compact flagship with industry-leading single-core CPU performance, a tightly integrated ecosystem, and prioritize video recording quality. Buy the Samsung Galaxy S23 Ultra if you prefer a larger display, longer battery life, a more versatile camera system with greater zoom capabilities, and the flexibility of the Android operating system.

Frequently Asked Questions

❓ Does the A17 Pro chip in the iPhone 15 Pro get noticeably hotter than the Snapdragon 8 Gen 2 during extended gaming sessions?
While the A17 Pro is incredibly powerful, its smaller 3nm node and efficient design should mitigate excessive heat. However, the Snapdragon 8 Gen 2’s 4nm process and larger die size offer excellent thermal headroom, potentially resulting in less throttling during prolonged gaming. Real-world testing is needed to determine which device maintains peak performance for longer.
❓ Is the 2MP macro camera on the Galaxy S23 Ultra actually useful, or is it just a marketing gimmick?
The 2MP macro camera on the S23 Ultra, while present, is often considered a secondary feature. Its limited resolution and fixed focus distance mean it doesn’t offer the same level of detail or flexibility as dedicated macro lenses found on some other smartphones. It’s usable for casual close-up shots, but serious macro photography enthusiasts will likely be disappointed.
❓ Does the iPhone 15 Pro support 90fps or 120fps gameplay in demanding titles like PUBG Mobile?
The iPhone 15 Pro’s A17 Pro chip and ProMotion display are capable of rendering games at high frame rates. While specific support depends on the game developer, the iPhone 15 Pro is expected to support 60fps and potentially higher frame rates (90fps or 120fps) in optimized titles like PUBG Mobile, offering a smoother and more responsive gaming experience.
❓ How does the iPhone 15 Pro's MagSafe charging compare to the S23 Ultra's wireless charging in terms of convenience and speed?
MagSafe offers a more secure and convenient wireless charging experience due to its magnetic alignment. However, both devices support 15W wireless charging. The S23 Ultra uses the standard Qi wireless charging protocol, while the iPhone 15 Pro also supports Qi2 (with iOS 17.2), potentially offering slightly improved efficiency. The iPhone 15 Pro's MagSafe ecosystem also allows for attaching accessories.
