Nubia NaviX Ultra AI phone launches with Doubao and 7,100mAh battery

Nubia’s NaviX Ultra is its second attempt at an AI-first phone, and this one leans harder into hardware. The China launch pairs ByteDance’s Doubao Mobile Assistant with Qualcomm’s Snapdragon 8 Elite Gen 5, plus a 200MP triple camera, a 7,100mAh battery, and 90W wired charging.

The Nubia NaviX Ultra AI phone launches with Doubao Mobile Assistant and a massive 7,100mAh battery. It also packs the Snapdragon 8 Elite Gen 5 chip and a 200MP camera, combining AI features with flagship-level hardware.

That combination gives the phone a clearer identity than Nubia’s earlier M153 effort, which reportedly did not land as strongly. In the NaviX Ultra, the company is trying to make AI feel built in rather than added later, with new controls, screen-aware features, and broader assistant actions across everyday tasks.

AI button fingerprint sensor and full-duplex voice model define the control system

The standout hardware change is the orange-accented AI button, which Nubia says also works as a fingerprint sensor. The company calls that an industry first. It is a small detail, but it changes how the phone is meant to be used day to day, since the AI entry point and unlock function sit in the same place.

Nubia NaviX Ultra AI phone launches in China with Doubao Mobile Assistant, a 7,100mAh battery, Snapdragon 8 Elite Gen 5, and a 200MP camera, offering a powerful AI-focused smartphone package.

That button ties into a full-duplex voice model, which means the assistant is designed to handle back-and-forth speech more naturally. Nubia also says Chinese dialect voice support is included. In practice, that suggests the company wants the assistant to stay usable in noisy settings, while the user is moving around, or when interaction is not perfectly controlled.

This is where the NaviX Ultra feels more deliberate than a typical phone with an assistant app tucked inside. The control system is part of the device design, not just software running in the background. For an AI-first phone, that matters.

Screen-aware AI shopping and app handoff aim to make Doubao useful

Beyond voice, the phone can read what is on screen, identify products through the camera, and move users into a shopping page without leaving the assistant. That gives Doubao a more practical role, since it is not limited to answering questions or opening apps. It can also react to what the user is already looking at.

Nubia says Doubao can also book rides, check schedules, and summarize meetings inside third-party services. Those are the kinds of tasks that usually get mentioned in AI phone launches, but here they are tied to a more specific idea: folding the assistant into everyday Android workflows instead of making it feel separate from them.

The broader picture is fairly clear. Nubia is treating the NaviX Ultra as a corrective to the M153, which had a more limited reception. The new model still needs real-world testing before anyone can judge how well the AI features work, but the direction is obvious. More hardware support, more direct control, and a stronger push to make the assistant useful in ordinary tasks. That is the bet Nubia is making with this launch.
