LG Gram Pro 16Z90TS Review (2025): Ultra-Light Copilot+ Workhorse with Long Battery Life

Introduction

Choosing the right laptop in 2025 often comes down to balancing performance, portability, and reliability. The LG Gram Pro 16Z90TS-G.AU89G stands out as one of the lightest 16-inch laptops available, equipped with Intel’s Lunar Lake Core Ultra 7 processor and a 77Wh battery promising up to 20 hours of endurance. In this review, I’ll share first-hand insights, expert analysis, and trusted references to help you decide whether this is the right machine for your needs.

My Experience Using the LG Gram Pro 16

I spent time working with the Gram Pro 16 as a daily driver for productivity tasks — from writing and research to light photo editing and streaming. The 1.23 kg weight made a noticeable difference compared to other 16-inch laptops I’ve used, especially when carrying it in a backpack for long commutes.

The 77Wh battery comfortably lasted a full workday and beyond, which gave me confidence that I didn’t need to carry the charger everywhere. The 144Hz 2.5K display felt smooth for everyday tasks and presentations, although brightness under direct sunlight could be better.

Expert Analysis of Key Features

Performance & Efficiency

Powered by Intel’s Core Ultra 7 256V (Lunar Lake) and Arc 140V integrated graphics, the Gram Pro 16 is designed for productivity, multitasking, and AI-accelerated tasks via its NPU. It’s not meant for heavy gaming or demanding 3D rendering, but for office workflows, content creation, and AI features, it runs smoothly.

Display & Visuals

The 16-inch IPS panel with a 2560×1600 resolution and 144Hz refresh rate offers sharp visuals and fluid motion. Color accuracy is decent out of the box, though professionals in creative industries may want to calibrate the panel for precision.

Battery Life

Independent tests from Notebookcheck confirm the Gram Pro 16 can achieve 18–20 hours of real-world use, which aligns with my own experience. This makes it one of the longest-lasting 16-inch laptops available.

Build Quality & Portability

At just 1.23 kg and ~13 mm thin, the LG Gram Pro 16 is significantly lighter than rivals like the ASUS Vivobook S16 or Lenovo Slim Pro 16. The chassis feels sturdy enough, although the ultra-light build sacrifices some of the premium rigidity you’d find in heavier competitors.

Connectivity

With USB-C (USB4), HDMI, USB-A, WiFi 6E, and Bluetooth 5.4, the laptop provides enough versatility for work and entertainment setups.

Pros & Cons

✅ Pros:

• Extremely lightweight for a 16-inch laptop (1.23 kg)
• Up to 20 hours of battery life

Trustworthy Verdict

The LG Gram Pro 16Z90TS is one of the best laptops in 2025 if you value portability, battery life, and modern features over raw GPU power. It is an ideal choice for students, business travelers, and professionals who need a reliable, long-lasting machine for productivity and light creative work.

If you’re looking for a gaming laptop or workstation replacement, you may want to explore alternatives like the MSI Vector 16 HX. But for anyone seeking an ultra-light, trustworthy productivity companion, the Gram Pro 16 delivers exactly what it promises.
