Key published specifications for each selected phone.
⚠ Some specifications are based on currently reported information and may change.
Each card names the phone with the higher measured value, or the lighter/thinner body. No overall winner.
A short list generated from the compared specifications.
Follow each link to verify the stored specifications and benchmark samples.
A highlighted percentage compares the higher measured value with the lower value, using the lower value as the baseline. Larger screens are physical differences, not overall wins; lighter and thinner describe size and weight. Specifications vary by region and configuration; Galaxy S24 Ultra weight is the 232 g Sub6 variant. Samsung battery values are typical capacities; capacity is not a battery-life result. The iPhone 18 Pro and Pro Max mAh values are for EU models and come from Apple's EU product information sheets. Wired adapter ratings describe the adapter used for a published fast-charge claim, not the measured charging draw or a shared charging-speed test. RAM varies by storage configuration or market for some models, so those presets leave the single RAM value blank. Other iPhone battery capacities are omitted here until a device and region-specific source is added. Brightness values here are manufacturer-rated outdoor peaks and are only comparable within the same published test description. Video playback is a manufacturer claim and is not compared across brands. Geekbench 6 CPU scores, where present, come from Tom’s Guide lab results across its 2025 and 2026 coverage; results vary by device, run and software. Missing scores remain unavailable. Camera details describe hardware and modes, not image quality.
