Design and Build Quality
iQOO Z11x Design Experience
The iQOO Z11x provides a great build at an affordable price. The matte-like surface on the phone’s rear part avoids many fingerprints. Additionally, the phone’s massive 6000mAh battery makes it smooth to use even after long-term gaming sessions, considering its weight of almost 199 grams.
I found this really impressive about the iQOO Z11x:
- Improved grip while gaming
- The fingerprint sensor on the side works faster
- The backside is more elegant than anticipated
In hot weather, I have not experienced any uncomfortable warming of the phone.
Redmi Note 15 SE 5G Design Experience
From its front side, the device appears to be somewhat higher in terms of build quality owing to thinner bezels. Xiaomi’s design is rather contemporary, particularly for those who are using Redmi phones for the first time.
However, because the phone is smooth, fingerprints are quickly left on its back.
It offers improved aesthetics for one-handed use because it is shorter compared to the iQOO Z11x variant.
Positives:
- Compact body
- Lighter design
- Improved camera module aesthetics
However, the overall construction does not seem as solid as that of the iQOO.
Winner: iQOO Z11x
