Reviews for the Xiaomi Redmi 15C 4G

70.5% Xiaomi Redmi 15C 4G smartphone review - Ideal second phone with 120 Hz display & audio jack? | Notebookcheck
The Redmi 15C 4G offers a lot for very little money: A PWM-free 120 Hz screen, for example, and a large battery. While you will get your money's worth if you want a large screen, there are disadvantages to the inexpensive phone for the reader to be aware of.
Redmi 15C Review: Are the slight upgrades worth it?
Source: Unbox English
The Redmi 15C feels more like a modest update to last year’s Redmi 14C with a bigger battery, slimmer design, and faster charging speeds, but the changes in pricing makes it a better offering if you opt for at least the 6GB/128GB variant.
