Hello Yes everything runs like butter is a great mobile phone but what irritated me was that it was extremely dusty for being refurbished but otherwise all good.

The Asus Zenfone 11 Ultra, released in March 2024, is the latest addition to Asus’s lineup, bringing a large display and flagship performance to users who want everything but the kitchen sink in their smartphone. Only one generation old as of 2025, it stands out with its powerful internals and a robust camera system, making it suitable for demanding daily use well into the future.
Key features:The Asus Zenfone 11 Ultra is made for users who won’t compromise on screen size or performance. It’s ideal for mobile gamers, multitaskers, and social media power users who want a large, vibrant display and a camera ready for everything from pet portraits to panoramic landscapes. If you’re deciding between this and older Zenfone models, the 11 Ultra steps up with its speedy Snapdragon 8 Gen 3, advanced camera setup, and future-ready Wi-Fi 7. Be aware, though—it’s not the most pocket-friendly phone out there.
Pros & Cons:| Pros | Cons |
|---|---|
| Large AMOLED display with up to 144Hz refresh rate—great for gaming and streaming. | Chunky build—definitely not one for small pockets or one-handed use. |
| Triple rear camera system including a telephoto lens with optical zoom. | No official IP rating—not the best if you’re clumsy around puddles. |
| High-end Snapdragon processor keeps things speedy for years. | Software customisation might not be everyone’s taste if you like “pure” Android. |
| Wi-Fi 7 support for the fastest wireless connectivity going. | Big size can feel unwieldy for some users. |
