What you should know
Why this 2024 phone still matters
ASUS Zenfone 11 Ultra is a deliberate break from the Zenfone’s compact heritage: a 6.78-inch display and 5,500mAh battery make it an ordinary-sized flagship with uncommon ASUS camera and software touches.
Hardware and real trade-offs
GSMArena called the size jump surprising. The full-width chassis helps battery and thermals but eliminates the single-hand selling point many Zenfone 9/10 owners wanted. Compare it against mainstream big flagships rather than against the small Zenfone 10. The manufacturer documentation lists display as 6.78-inch up to 144 Hz AMOLED. The manufacturer documentation lists battery as 5500 mAh. The manufacturer documentation lists charging as 65W wired.
What independent reviewers found
The GSMArena assessment specifically discusses 6.78-inch screen shifts Zenfone away from compact roots and towards broad flagship use.
Software lifespan and regional compatibility
For October 2026 ownership planning, the recorded update policy is: A model-specific long-term OS and security commitment is not established in the currently attached primary sources; verify the vendor support page and the exact sales market. Check the original country model, radio bands, carrier lock status, eSIM and local manufacturer repair coverage before treating an imported handset as interchangeable with the domestic version.
Who should consider it in October 2026?
For owners wanting larger media and navigation space; avoid if you expected a one-handed Zenfone successor. In October 2026, a discounted 2024 flagship can remain compelling, but compare its actual used condition and software support with a new midranger. A promotional AI feature or camera megapixel count is not an independent quality measurement.
Alternatives and buying conditions
ASUS ROG Phone 8 for gaming controls; Galaxy S24+ for Samsung support. Distinct storage, carrier and national SKUs are treated as variations of this model, not separate phones, unless different essential hardware is verified. A practical comparison should also include battery health, camera condition and remaining updates; compare this with the asking price and warranty on the exact device offered.
