I25 Ultra Unlocked Smartphone 16+512GB Wine Red - Big Battery & S Pen

Our review of the I25 Ultra Unlocked Smartphone summarizes who will get the most from this large-screen, unlocked Android device and the single biggest reason to buy it: its combination of a massive 7000mAh battery and included S Pen makes it a practical all-day device for power users who sketch, take notes, or multitask. The I25 Ultra runs Android 14 and pairs a 6.99 in HD+ display with a high-resolution 108MP rear camera and a 68MP front camera, so it aims to serve mobile photographers and heavy app users without tying them to one carrier.

Key Features

• 6.99 in HD+ display: A large 14403040 screen gives ample workspace for viewing documents, watching videos, and drawing with the included S Pen.
• 7000mAh battery: A very large battery supports long days of use and gaming without frequent recharging, reducing anxiety for heavy users.
• Snapdragon 8 Gen3 CPU: A 12-core processor with 16GB RAM and 512GB storage handles multiple apps and demanding tasks simultaneously.
• Pro-grade S Pen included: The 4096-pressure stylus with magnetic attachment enables precise note taking, photo editing, and sketching without buying an accessory separately.
• High-resolution cameras: A 108MP main camera and 68MP front camera capture detailed photos and clear selfies for social sharing or casual content creation.
• Dual SIM and global bands: Two 5G SIM slots plus a dedicated microSD slot let users run two numbers and expand storage for travel or business use.

Who It's For

The I25 Ultra suits mobile professionals, students, and creators who need long battery life, a large screen for reading or drawing, and the convenience of a built-in S Pen for handwriting and precise editing. Its large memory and storage make it attractive to people who keep many apps and media files on-device.

Users who prioritize the very latest camera software features, ultra-compact size, or a lightweight pocket phone should look elsewhere; the I25 Ultra is sizable and geared toward endurance and productivity rather than minimalism.
