The livestream audience was already sold on the Harmony X2's core specs.
A 2K screen. A monster chip. Flagship-tier cameras. Fans were calling it the best Chinese phone ever made.
But Liu Jianyu hadn't even gotten to the best part.
"Now," he said, stepping forward, "let's talk about what makes the Harmony X2 truly different."
"Let's talk about black tech."
The chat erupted.
"Black tech? Finally!"
"This is what I came for."
"He's been teasing this all week!"
While most features had already been leaked or posted on Weibo, this was the last big unknown.
The audience leaned in. Even the trolls went quiet.
Jianyu gestured toward the big screen.
"Harmony X2 comes equipped with a 3,500mAh battery and supports 35W fast charging."
"That's three times faster than most phones on the market."
"Lab tests show it charges from 0 to 100% in 51 minutes."
The chat blew up again.
"WHAT??"
"Less than an hour?!"
"My phone takes three HOURS!"
"Battery anxiety? Deleted."
Most phones—even high-end ones—were still stuck at 20W or 25W.
Samsung's S6 topped out at 25W. Apple was even slower.
But CS was now pushing 35W in a production phone—and backing it with solid battery quality.
Jianyu wasn't done hyping.
"We've heard your pain. Slow charging kills your day."
"So we brought high-efficiency fast charge tech, tuned for Harmony OS, and optimized for Kunpeng A2."
"It's safe. It's fast. It's built for people who live on 10% battery."
Then, with a sly grin, he added:
"Charge for five minutes. Talk for two hours."
The line hit like a hammer.
The chat repeated it in waves:
"Charge five, talk two!"
"Borrowed from Oppo, huh?"
"Hey, marketing is marketing."
Initially, that slogan had been coined for an Oppo launch slated for next year. But Haifeng had shamelessly swiped it early.
Did anyone care?
Nope. They loved it.
With the audience still reeling, Jianyu grinned again.
"But that's not all."
"We have one more surprise—also about charging."
"We even shot a full promo for it. It'll go live across all major platforms after this event."
"But why wait? Let's watch it together."
He stepped aside.
The room dimmed.
The big screen lit up with a short video—thirty seconds max.
The star?
Sun Dongmei, a rising singer, was made famous through reality shows. Talented, low-profile, and widely beloved.
In the ad, she's in the studio recording a demo. But halfway through, her voice falters.
She's tired. Pushing herself.
Then her phone beeps—battery low. And it dies.
The audience knew what was coming. It was obvious. But it didn't matter.
They were locked in.
Onscreen, she walks to a table.
There's a small, clean, white disc—minimalist and modern.
She places her Harmony X2 on it.
Ding.
A soft chime.
A charge icon appears on her screen.
The chat exploded.
"NO WAY."
"That's wireless charging!"
"THEY ADDED IT!"
"This is it. I'm buying."
The video ends with four words across the screen:
"The era has arrived."
Wireless Charging.
Back in the livestream, silence turned to full-blown hype.
"35W fast charging and wireless???"
"Samsung's in trouble."
"This thing is unfair."
"When does pre-order start?!"
The Harmony X2 was pulling ahead. And there was still more to come.
