What customers dislike about Xiaomi Redmi 15 4G (8GB + 256GB)?

Performance is considered a major weakness, with the Snapdragon 685 processor struggling with heavy gaming and sometimes feeling laggy in daily use.
Camera performance is generally mediocre, especially in low light conditions, and lacks an ultra-wide sensor.
Charging speed is slow (33W wired for a 7,000 mAh battery), taking around two hours for a full charge, and lacks wireless charging support.
Only has a single, mono loudspeaker, which delivers flat sound quality, a drawback compared to competitors offering stereo speakers.
The large battery and screen make the phone heavy and large, not suitable for users preferring a compact, lightweight device.
Lacks 5G connectivity and a 3.5mm headphone jack.
Display is an IPS LCD panel, not AMOLED, so it has less vibrant colors and deep blacks compared to some competitors in the same price range.
Some users report UI bugs and a less polished software experience compared to other brands.
