I24 Ultra Unlocked Phone with Built-in Pen - Large Battery

Our review of the I24 Ultra finds it best suited for users who want a large-screen Android phone with long battery life and generous on-board memory. The single biggest reason to consider this model is its combination of a 6800mAh battery and 16GB+512GB memory, which together make it a practical choice for heavy daily use, media consumption and multitasking without constant charging or storage anxiety. It is an unlocked Android 14 device with a built-in pen, so it appeals to power users who value productivity on a big display.

Key Features

• Large battery: The 6800mAh battery provides extended runtime so users can stream, game or work through a full day without frequent recharging.
• High capacity memory: The 16GB RAM and 512GB internal storage handle multiple apps and large files, and adding a 128GB TF card expands storage further.
• Big HD display: The 6.82in HD+ screen with 14403040 resolution makes reading, video and multitasking comfortable on a wide canvas.
• Camera setup: A 108MP rear camera and 48MP front camera offer high-resolution imaging for photos and video calls.
• Security options: Face ID and screen fingerprint unlocking provide two quick biometric ways to protect personal data.
• Dual SIM and global 5G: Dual SIM/TF card slot and broad 5G band support suit travelers and users who need two active numbers.

Who It's For

The I24 Ultra is a solid choice for multitaskers, mobile professionals and media consumers who need long battery life, a large screen and abundant memory for apps, photos and offline media. The built-in pen also makes it useful for note taking and light creative tasks without adding an accessory.

It may be less appropriate for someone who prioritizes the absolute lightest pocketable phone or expects flagship-level camera tuning and ultra-premium build; customer feedback shows mixed impressions on build quality, so buyers seeking the highest-end fit and finish might want to compare alternatives first.
