Xiaomi 12S Ultra

The Xiaomi 12S Ultra is a dual-camera powerhouse that boasts impressive specs, but its performance is uneven. The phone's main camera, backed by Leica's color science, delivers stunning results with rich and cinematic shots. However, the ultrawide camera struggles to produce accurate colors, particularly when switching between modes. In contrast, the Samsung Galaxy S series, although not as strong in the main camera department, excels with its ultrawide and zoom cameras. The overall color science of the Samsung phone is also more pleasing, especially when capturing skin tones. Battery life is another area where both phones shine. Despite having a slightly lower battery capacity, Xiaomi's 12S Ultra manages to keep up with Samsung's power-hungry device, thanks to its more efficient chip. Wireless charging speeds are also significantly faster on the Xiaomi phone, making it a clear winner in this department. Charging times and software features further sway the balance towards Xiaomi. The company's battery management software is intuitive and helpful, while its charging capabilities outpace those of Samsung. Ultimately, the Xiaomi 12S Ultra is a capable camera phone that edges ahead in some areas but lags behind in others. If you prioritize photography, this phone may be worth considering, but if other features like battery life, charging speed, or software are more important to you, Samsung's offerings might still take the cake. Both phones have their strengths and weaknesses. While Xiaomi takes the lead in some areas, Samsung excels in others. The decision ultimately comes down to your personal priorities.
