My Choice

If I had to choose between these two, I would choose the Apple iPhone 12 mini. My priority when choosing a smartphone is a fluid user experience with performance and a high quality camera. While the Samsung Galaxy M15 has a much larger battery and screen, the iPhone 12 mini wins in terms of responsiveness and image quality. The higher pixel density of the iPhone 12 mini display, combined with its premium build and camera quality makes it a better option for daily use. I also have experience using the Apple ecosystem, so moving to another iOS device would be the most natural transition for me. Though its smaller size may not appeal to everyone, I prefer a smaller and more compact device for one-handed use, which is another reason for my preference. Ultimately, the significantly better processing power and camera on the iPhone 12 mini are worth more to me than the larger screen and battery of the Samsung Galaxy M15.
