Display Comparison
The iQOO 15 boasts a significantly brighter display, reaching a measured 2933 nits, compared to the OnePlus 12R’s 1181 nits. This difference is immediately noticeable in direct sunlight, where the iQOO 15 remains easily readable. While both likely utilize AMOLED panels, the iQOO 15’s higher peak brightness suggests a more advanced panel technology. We expect the iQOO 15 to offer superior HDR content viewing. Details regarding refresh rate and PWM dimming are missing, but the brightness difference is a key differentiator.
Camera Comparison
Without detailed camera specifications, a direct comparison is limited. However, given the iQOO 15’s focus on performance, it’s reasonable to expect a capable camera system. The OnePlus 12R likely benefits from OnePlus’s established image processing algorithms. The absence of information regarding sensor size and OIS makes it difficult to assess image quality definitively. We anticipate both phones will offer acceptable camera performance for social media and casual photography, but the iQOO 15’s processing power could provide an edge in computational photography features.
Performance
The iQOO 15’s Qualcomm SM8850-AC Snapdragon 8 Elite Gen 5 (3nm) represents a substantial leap in performance and efficiency over the OnePlus 12R’s Snapdragon 8 Gen 2 (4nm). The iQOO 15’s octa-core CPU, featuring Oryon V3 Phoenix cores clocked up to 4.6 GHz, promises faster processing speeds for demanding applications and gaming. The 3nm process node of the Snapdragon 8 Elite Gen 5 translates to improved thermal efficiency, potentially reducing throttling during sustained workloads. While the Snapdragon 8 Gen 2 is still a powerful chip, the iQOO 15’s processor offers a clear advantage in raw performance and sustained performance.
Battery Life
The iQOO 15 delivers a remarkable 21:47h of active use, significantly outperforming the OnePlus 12R’s 14:32h. This difference is primarily attributable to the more efficient Snapdragon 8 Elite Gen 5 chipset. Both phones support 100W wired charging, with the OnePlus 12R claiming a full charge in 26 minutes. The iQOO 15 adds 40W wireless charging and bypass charging, offering greater charging flexibility. While the OnePlus 12R’s charging speed is competitive, the iQOO 15’s superior battery life and wireless charging capabilities provide a more comprehensive charging experience.
Buying Guide
Buy the vivo iQOO 15 if you need exceptional battery life for all-day use, a vibrant and bright display for outdoor visibility, and the latest Snapdragon processing power for demanding tasks. Buy the OnePlus 12R if you prioritize a well-rounded experience with fast 100W charging, a familiar OxygenOS interface, and a slightly more established ecosystem of accessories and support.
