• Solid Performance: Under the hood, the SnapD. 8 Elite Octa-Core is supported by 12 GB of RAM. The AnTuTu score of 2,265,528 testifies to considerable firepower, even if the performance rating (4/5) places it slightly behind the Xiaomi.
• High-Resolution Photography: Samsung bets on an impressive 200 MP main sensor. On paper, it’s huge! The overall photo rating is 4/5, indicating very good capabilities, but suggesting that megapixels aren’t everything.
• Battery Life & Storage: A 5000 mAh battery (battery life rating 4/5) and a comfortable storage capacity of 512 GB complete the picture.
• Overall Rating: An excellent 5/5.

• The King of Performance? With the same SnapD. 8 Elite Octa-Core but boosted by 16 GB of RAM, the Xiaomi 15 Ultra reaches a stratospheric AnTuTu score of 2,746,580. The 5/5 performance rating confirms its dominance in this field.
• Optimized Photography: Xiaomi opts for a 50 MP main sensor. Fewer megapixels than the Samsung, but a higher photo rating of 5/5, suggesting fearsome software and hardware optimization.
• Endurance and Storage: The battery climbs to 5410 mAh (battery life rating 4/5, identical to the Samsung despite the higher capacity) and storage is also 512 GB.
