The design of the Redmi Note 11S is a bit too bland. The plastic frame and back panel are well built and the phone is quite comfortable to hold. 
Xiaomi has gone for a 6.43-inch AMOLED display with a pretty high peak brightness of up to a claimed 1000nits. This phone is powered by the MediaTek Helio G96 SoC. The Redmi Note 11S runs MIUI 13, but this version is still based on Android 11 and not 12.

The Redmi Note 11S offers enough grunt to handle basic apps and games well. Certain apps in MIUI 13, such as GetApps, can be spammy. Videos looked good on the phone’s display but the stereo sound wasn’t well balanced as the bottom speaker sounded a lot clearer than the earpiece. Battery life was thankfully pretty good. The 5,000mAh battery easily offered an entire day’s worth of runtime, even with heavy use. The 108-megapixel camera is this phone’s main selling point. It can capture good photos if you’re shooting at the native resolution during the day, but otherwise it’s strictly average, as are the rest of the sensors.

I think it would be best to hold off for a while before you make any purchase decision regarding this phone, as better options are sure to launch soon.
