vivo iQOO 15
- Blazing-fast Snapdragon 8 Elite Gen 5 performance
- Incredibly fast 100W wired and 40W wireless charging
- Significantly brighter display for outdoor visibility
- Shorter battery life compared to the S24 FE
- Software experience may not be as refined as Samsung’s One UI
Samsung Galaxy S24 FE
- Exceptional battery life and longevity (2000 cycles)
- Polished software experience with Samsung’s One UI
- Reverse wireless charging for accessories
- Less powerful processor than the Snapdragon 8 Elite Gen 5
- Slower charging speeds compared to the iQOO 15
Display Comparison
The iQOO 15 boasts a significantly brighter display, reaching a measured 2933 nits compared to the S24 FE’s 1372 nits. This translates to superior visibility in direct sunlight. While both likely utilize OLED panels, the iQOO 15’s higher peak brightness and potentially higher PWM dimming rate (data unavailable) could make it more comfortable for prolonged use, especially for users sensitive to flicker. The S24 FE benefits from Samsung’s display expertise, likely offering excellent color accuracy, but it can’t match the iQOO 15’s sheer luminance.
Camera Comparison
Without detailed camera specs, a direct comparison is difficult. However, the S24 FE likely benefits from Samsung’s established image processing algorithms and potentially larger sensor sizes. The iQOO 15’s camera performance will depend heavily on its sensor and lens choices, which are currently unknown. It’s reasonable to assume the S24 FE will offer a more consistent and refined camera experience, particularly in challenging lighting conditions. The presence of a 2MP macro camera on either device is largely irrelevant, offering minimal practical benefit.
Performance
The iQOO 15’s Qualcomm SM8850-AC Snapdragon 8 Elite Gen 5 (3nm) is a substantial leap forward in mobile processing. Its octa-core configuration, featuring Oryon V3 Phoenix cores clocked up to 4.6 GHz, promises significantly higher CPU and GPU performance than the S24 FE’s Exynos 2400e (4nm). The Exynos 2400e’s 10-core design attempts to compensate with core count, but the architectural advantages and smaller node of the Snapdragon 8 Elite Gen 5 should result in superior sustained performance and thermal efficiency. This means less throttling during extended gaming sessions on the iQOO 15. The iQOO 15 also benefits from faster LPDDR5x RAM, further enhancing responsiveness.
Battery Life
The Galaxy S24 FE’s 42:00h endurance and 2000 cycle rating is a major advantage. While the iQOO 15 delivers a respectable 21:47h of active use, the S24 FE’s longevity is significantly higher. The iQOO 15 compensates with incredibly fast 100W wired charging (with PPS and PD support) and 40W wireless charging, allowing for a full charge in a fraction of the time compared to the S24 FE’s 25W wired charging. The S24 FE also offers reverse wireless charging, a feature absent on the iQOO 15. The iQOO 15’s bypass charging feature, allowing direct power from the charger to the phone while in use, is a unique benefit for gamers.
Buying Guide
Buy the vivo iQOO 15 if you demand the absolute fastest performance for gaming and demanding applications, and value incredibly rapid charging. You're willing to trade some battery life for this speed. Buy the Samsung Galaxy S24 FE if you prioritize all-day battery life, a polished software experience with Samsung’s One UI, and a more balanced feature set, even if it means sacrificing some peak performance.
