Limited Storage Options: While 128GB of storage may be sufficient for many users, some may find it lacking, especially if they store a large amount of media or install numerous apps and games.

No Expandable Storage: The absence of a microSD card slot means you can’t expand the storage capacity beyond the built-in 128GB. This limitation may be a concern for users who frequently require extra storage space.

Availability: Depending on your region, the iQOO Z9 5G may not be widely available, which could make it difficult to purchase or obtain support and accessories.

Price: While the device offers high-end features, its price point may be relatively high compared to other smartphones with similar specifications. This could be a deterrent for budget-conscious consumers.

Battery Life: While fast charging is convenient, the overall battery life of the device may not be as long-lasting as some competing models, especially under heavy usage scenarios.

Camera Performance in Low Light: Despite the presence of optical image stabilization, the camera’s performance in low-light conditions may not be as impressive as some flagship smartphones with dedicated night mode features.
