My Choice: Xiaomi 13 Ultra

While the Samsung Galaxy M15 offers a larger battery and a lower price, the Xiaomi 13 Ultra is the clear winner for me. Its superior performance, stunning display, and advanced camera system make it a compelling device. I prioritize a smooth and responsive user experience, high-quality visuals, and the ability to capture excellent photos and videos. The price difference is significant, but the Xiaomi 13 Ultra offers a substantial upgrade in almost every aspect of the user experience. The larger battery of the M15 is tempting, but the Xiaomi's LTPO display likely offsets the difference in battery capacity in real-world usage. The investment in the Xiaomi is justified by its significantly better overall experience for my needs.
