• Non-Expandable Storage: The 128 GB storage might not be expandable via microSD card, limiting flexibility for users who require additional storage space.

• Plastic Build: If the phone features a plastic body, it may not feel as premium or durable compared to metal or glass-bodied smartphones.

• Camera Performance in Low Light: Despite having multiple cameras, the performance in low-light conditions may not be as impressive as more expensive models with advanced night photography features.

• Software Updates: While it runs on Android with a custom POCO interface, the frequency and longevity of software updates may vary compared to flagship devices.

• Display Quality: Depending on the specific panel used, the display quality (brightness, color accuracy, etc.) might not match higher-end smartphones.

• Audio Quality: The quality of speakers and audio output through headphones might be average, affecting the overall multimedia experience.

• Availability of Accessories: Limited availability of official accessories or third-party options specifically designed for the device could be a consideration for some users.

• No Wireless Charging: Some users may miss the convenience of wireless charging, which is not typically included in budget-friendly smartphones.

• Performance Longevity: While the processor and RAM are sufficient for current usage, future-proofing for intensive apps and games may be a consideration as technology advances.

• Network Compatibility: Although it supports 5G, the compatibility with specific carrier bands may vary, so users should check if it supports the bands used by their network provider.

These cons should be weighed against the pros and the intended use case to determine if the POCO M6 Pro 5G (128 GB) (6 GB RAM) (Power Black) meets your specific needs and expectations in a smartphone.
