HelioBook 14 Ultra Review

The trade-off this laptop is built around

Every thin 14-inch laptop makes the same bargain: cut thickness, cut cooling, cut sustained power. The HelioBook 14 Ultra is unusually honest about it. Helio publishes the 28 W sustained figure rather than burying it, and the machine is designed around that number instead of pretending otherwise.

That makes it easy to recommend or reject. If your workload is bursty, you will only ever see the 45 W boost behaviour and the laptop feels fast. If your workload is sustained, you will live at 28 W and a thicker machine at the same price will beat it.

Display

This is the standout feature. The 2.8K OLED panel covers effectively the full DCI-P3 gamut, arrives calibrated close enough that most people will never touch it, and runs at 120 Hz. Blacks are true black, which makes a real difference for video and dark-mode work.

The glossy finish is the catch. Near a window you will see yourself. There is no matte configuration.

Performance in practice

For the work most buyers actually do, performance is not the limiting factor. Thirty browser tabs, a code editor, a video call and a music app run together without stutter. Compilation and photo edits finish quickly because they fall inside the boost window.

Where it slows down

Start a twenty-minute video export and the pattern changes. Clock speeds drop after the second minute and settle. The export still completes, just noticeably slower than the same chip in a thicker chassis. If that is your daily job, this is the wrong laptop.

Battery and charging

The 70 Wh cell is large for this weight class, and the efficient panel helps. A realistic office day at 40 percent brightness runs 9 to 10 hours. Charging over USB-C from any 65 W adapter reaches roughly 50 percent in half an hour.

Build, keyboard and ports

The aluminium chassis has very little lid flex. The keyboard is the quiet highlight, with 1.5 mm of travel and a firm bottom-out that makes long typing sessions comfortable.

Port selection is the practical win. Two USB-C, one USB-A, full HDMI 2.1 and a headphone jack means you can plug into a meeting room projector and a legacy drive without carrying a hub.

Verdict

A strong buy for portable, bursty work with an outstanding screen. A poor buy if you render, compile or game for long stretches.
