Display Comparison

Both the iQOO Pro and Realme X2 Pro feature displays with an 'Infinite' (nominal) contrast ratio, suggesting excellent black levels typical of AMOLED panels. However, specific details like peak brightness and color accuracy are missing. Given Realme’s history with vibrant displays, it’s likely the X2 Pro leans towards a more saturated look, while iQOO might aim for greater color accuracy. The lack of information on refresh rates (beyond standard 60Hz) is a notable omission, impacting smoothness for gaming and scrolling.

Camera Comparison

Both devices are listed as having 'Photo / Video' capabilities, but lack specific details. Without sensor size, aperture, or OIS information, a direct comparison is difficult. However, the market positioning suggests the Realme X2 Pro might prioritize camera versatility, potentially offering a wider range of shooting modes. The absence of details regarding image processing algorithms is also significant; Realme UI often emphasizes vibrant, social media-ready images, while iQOO might lean towards a more natural look. The inclusion of a 2MP macro lens on either device is likely a marketing gimmick with limited real-world utility.

Performance

Both phones are powered by the Qualcomm Snapdragon 855+ (7nm), but the Realme X2 Pro boasts a slightly higher peak CPU clock speed – 2.96 GHz versus 2.84 GHz on the iQOO Pro. While this difference is unlikely to be noticeable in everyday tasks, it *could* translate to marginally better performance in sustained, CPU-intensive workloads. Both utilize an octa-core configuration (1xKryo 485 prime core, 3xKryo 485 performance cores, and 4xKryo 485 efficiency cores). Thermal management will be crucial; the 7nm process is efficient, but prolonged gaming will generate heat. RAM configurations are not specified, but both likely offer LPDDR4X, a standard for this generation.

Battery Life

Both the iQOO Pro and Realme X2 Pro achieve an impressive Endurance rating of 94 hours, indicating excellent battery life. However, the key differentiator is charging speed. The Realme X2 Pro’s 50W SuperVOOC charging can fully charge the battery in just 35 minutes, a substantial advantage over the iQOO Pro’s 44W charging. While both offer comparable endurance, the X2 Pro’s faster charging minimizes downtime and provides a more convenient user experience. Battery capacity is not specified, but the charging speed suggests the X2 Pro may have a slightly larger cell.

Buying Guide

Buy the vivo iQOO Pro if you prioritize a slightly cleaner software experience and are less concerned with absolute charging speed. Buy the Realme X2 Pro if you value rapid charging, a potentially more aggressive price point, and don't mind Realme UI. Both phones are excellent for gaming and demanding tasks, but the X2 Pro’s charging speed offers a tangible daily benefit.

Frequently Asked Questions

❓ Will the Snapdragon 855+ in either phone struggle with demanding games like Genshin Impact?
The Snapdragon 855+ is still a capable chipset, but demanding games like Genshin Impact may require reduced graphics settings for consistently smooth frame rates. Both phones will likely experience some thermal throttling during extended gaming sessions, but the performance should remain playable.
❓ Is the 50W charging on the Realme X2 Pro compatible with all USB-PD chargers?
No, the Realme X2 Pro utilizes Realme’s proprietary SuperVOOC charging protocol. While it can charge with standard USB-PD chargers, it will do so at a significantly slower rate. You’ll need the included SuperVOOC charger to achieve the advertised 35-minute full charge time.
❓ How does Realme UI compare to vivo’s Funtouch OS in terms of bloatware?
Historically, both Realme UI and Funtouch OS have been criticized for pre-installed bloatware. However, Realme UI has made strides in recent versions to reduce unnecessary apps and offer a cleaner user experience. The amount of bloatware can also vary depending on the region and carrier.
