The I25 Ultra 5G Unlocked Smartphone positions itself as a feature-rich option for users who want a large-screen Android phone with a spacious storage capacity, dual SIM convenience, and extended battery performance. In this review, we take a closer and practical look at the device’s display quality, performance, camera system, battery life, usability, and care considerations to help determine who this smartphone is best suited for.
Display and Design
The I25 Ultra 5G features a 6.99-inch HD+ display, offering a wide visual field ideal for video viewing, browsing, social media, and general multitasking. The screen resolution is listed at 1440×3040, which contributes to sharper text and clearer visual details compared to standard HD screens.
Key characteristics of the display include:
-
Large Viewing Space: The nearly 7-inch display provides room for media consumption and split-screen multitasking.
-
Vivid Color Output: The screen is designed to produce bright colors and high contrast, offering a visually appealing experience.
-
Comfort for Reading: The extended vertical size gives more visible text per page when reading articles, e-books, or emails.
The device’s overall design includes a slim frame and a Gold finish, presenting a sleek appearance consistent with modern smartphone styling. Users who prefer phones with a bold presence and noticeable screen real estate may find the I25 Ultra particularly appealing.
System Performance and Storage Capacity
One of the central features of the I25 Ultra 5G is its 12GB of RAM and 512GB internal storage, which provides room for apps, photos, downloaded media, and large files. Additionally, the phone supports expanded storage up to 512GB with a memory card, providing flexibility for users who need even more space.
The phone is described as being powered by a Snapdragon 888+ Octa-Core processor, designed for smooth operation during everyday use. Performance capabilities may include:
-
Efficient App Switching: The high memory capacity supports multiple apps running concurrently.
-
Responsive Touch Navigation: The processor is optimized for fluid scrolling and quick UI responses.
-
Gaming and Streaming: Games and videos should run smoothly under moderate to high settings, depending on optimization and network conditions.
While the device is advertised as supporting 5G connectivity, actual speeds and coverage depend heavily on the user’s mobile network provider and regional availability of 5G infrastructure.
Software and User Interface
The phone runs on Android 13.0, offering:
-
Updated privacy settings
-
Improved notifications and app permission control
-
Cleaner visual layout and widget flexibility
Users who are familiar with recent Android phones should find the interface intuitive and straightforward. The phone supports facial recognition and screen fingerprint unlocking, offering multiple methods to secure access depending on user preference.
Camera System and Photography Capabilities
The I25 Ultra includes a 108MP main rear camera and a 48MP front-facing camera, aimed at delivering high-resolution images and clear selfies.
Rear Camera Usage
-
Suitable for outdoor photography under natural lighting
-
Supports portrait and landscape capture
-
Can document travel, family gatherings, and daily experiences
Front Camera Features
-
Optimized for video calls, selfies, and social media recording
-
Works with facial recognition for unlocking the phone
The overall camera performance will depend on lighting conditions. As with many smartphones in this price range, shots taken in low-light environments may show noise or reduced clarity. Users who primarily capture photos during the day or in well-lit indoor spaces may see the best results.
Battery Life and Charging
A significant strength of the I25 Ultra 5G is its 6800mAh battery, designed for extended usage without frequent charging breaks. This capacity allows:
-
Long hours of gaming and video playback
-
Multi-day standby time under moderate usage
-
Extended performance during travel or outdoor activities
The device supports 20W fast charging, which helps restore power more quickly compared to standard charging rates. While not the fastest charging technology available, it is practical for users who prefer minimal downtime.
Dual SIM and Connectivity
The phone supports Dual SIM functionality, which is beneficial for:
-
Users who manage separate work and personal numbers
-
Travelers who switch between local and international SIM cards
-
Individuals in areas where network coverage varies by provider
The SIM tray is shared with the TF memory card slot, meaning users may need to choose between dual SIM use or storage expansion depending on their needs.
The phone offers global band compatibility, though actual network support varies by country and carrier. It is recommended to check supported bands with your service provider before use.
Included Accessories and Build Considerations
This model is shipped with several included accessories, such as:
-
Built-in stylus pen
-
Screen protector
-
Earphones
-
Charger
Having these accessories included reduces the need for separate purchases, which can be convenient for users setting up the phone right out of the box.
Because the device has a large display and lightweight frame, users may want to apply a protective case to help prevent damage during drops or daily handling. Fold-free large screens generally benefit from careful carrying and storage to avoid scratches.
Ideal User Profile

| User Type | Why It Works |

| Users in Areas Without Strong 5G | Some features depend on stable network coverage. |

It is a device suited for users who value screen size, storage, and flexibility in daily use.
