I25 Ultra 6.99in FHD+ Android 14 Smartphone - Powerhouse Performance

Our review of the I25 Ultra finds it best suited for users who want a large display and long battery life without compromising speed. The single biggest reason to consider this phone is its combination of a huge 6.99in FHD+ screen, a 7000mAh battery and a robust 12GB RAM that keeps heavy multitasking and gaming fluid. In everyday use the phone feels fast and responsive, the built-in stylus adds genuine utility for handwritten notes and precision tasks, and the camera system produces highly detailed images in good light.

Key Features

• 12GB RAM Performance: Multitasking and app switching remain smooth under heavy loads, making editing and gaming feel uninterrupted.
• 512GB Storage: Massive onboard storage lets users keep hundreds of apps, thousands of songs and tens of thousands of photos without relying on cloud space.
• 6.99in FHD+ Display: The large edge-to-edge screen delivers vivid color and 500-nit brightness for comfortable media viewing and outdoor readability.
• 108MP + 68MP Camera System: The dual high-resolution sensors capture detailed daytime photos and offer an ultra-wide option for landscapes and group shots.
• 7000mAh Battery: Long endurance supports extended streaming or gaming sessions and fast 33W charging reduces downtime when recharging is needed.
• Built-in Stylus: The pressure-sensitive stylus is integrated for note-taking, sketching and precise edits without carrying extra accessories.

Who It's For

The I25 Ultra is aimed at power users who prioritize a big, cinematic screen and multi-day battery life, such as mobile content consumers, commuters, and students who annotate and sketch with a stylus. Creators who need high-resolution photos and sizable local storage will also appreciate the 108MP sensor and 512GB capacity.
