A 2016 graduate of Southeast University’s Electronics Engineering program, worked as an R&D engineer at Huawei for 3 years, then as a tech writer for Digital China magazine. He quit his job in2020 after realizing most tech reviews were either too technical (unaccessible to casual users) or too hype-driven (sponsored content masquer as advice).

Positioning: Li bills himself as a "data-first tech translator"—someone who takes complex specs (like ISO levels orbench scores) and turns them into actionable insights for everyday users. His tagline: "No fluff, just facts" reflects his commitment to: he never accepts free products without disclosing sponsorships, and he reserves the right to criticize even paid partnerships.

In an interview, Li said "When I was a consumer, I once bought a phone because a reviewer called it ‘the best battery life ever’—but it died in8 hours. That’s when I decided: I want to create reviews where every claim is backed by a test."

Pillar1: In-Depth Gadget Reviews (Data-Driven)

Li’s signature content is his flagship phone/laptop reviews. Unlike most reviewers who on design or UI, he runs quantitative tests:

• Battery: 24-hour endurance tests (video loops, gaming, social media with real-time power meters.
• Camera: Controlled environment tests (low light, portrait, action shots) using a test chart to measure sharp and noise.
• Performance: Geekbench/AnTuTu benchmarks + real-world tests (opening 10 apps in sequence, editing K videos).

Differentiation: He publishes full test data in the video description (e.g., "Phone X’s camera has 12 less noise than Phone Y in low light").

Pillar 2: Tech Myth-Busting

Li loves debunking misinformation. For example:

• A viral video titled "Is 5G faster than Wi-Fi 6? Let’s test 10 scenarios" showed that in most home settings, Wi-Fi 6 is faster (5G won only in open outdoor areas).
• Another clip: "Does your phone overnight damage the battery?"—he tested 3 phones for 6 months, finding no significant decrease in battery capacity.
