My Choice
I would choose the Xiaomi Mi 11. While the Samsung Galaxy A15 offers a newer OS, larger battery, and a lower price point, the Mi 11 wins by a large margin in almost all other criteria. The performance difference is night and day - the Snapdragon 888 in the Mi 11 is far superior to the Helio G99 in the A15. This means the Mi 11 will be smoother for all tasks, including intensive gaming and multitasking, while the A15 will be slow.
The display is another key factor, the Mi 11 has a sharper, brighter, and smoother screen, which is crucial for an enjoyable viewing experience. The camera system is also significantly better on the Mi 11 with higher resolutions, 8K recording, and OIS. The faster charging speeds and better audio on the Mi 11 are additional benefits.
Even though the Mi 11 is an older phone, it provides a much better experience overall, despite the trade offs in battery and updates, the massive improvement in all other areas is worth the compromise. The Mi 11 was a flagship phone when it was released and still packs a punch, while the A15 is an entry-level phone.
