Xiaomi Pushes Hardware Frontiers with Massive Battery and In-House Chip as Shares Languish Near Lows

Smartphone makers often talk about differentiation, but Xiaomi is taking an unusually aggressive approach on two fronts at once. The Chinese technology group has unveiled ambitious hardware upgrades across its upcoming smartphone lineup — a 7000 mAh battery for the 17T series and a fully self-engineered chip for the foldable MIX Fold 5 — even as its shares trade just above a 52-week low.

The moves reflect a company that is leaning hard into proprietary technology to justify higher prices, while its financials paint a less flattering picture. In the first quarter of 2026, profit plunged 57 percent to 4.72 billion yuan, and revenue slipped 11 percent to 99 billion yuan. The smartphone division contributed 44.3 billion yuan, though the average global selling price hit a record — a sign that Xiaomi is chasing value over volume.

Battery Breakthrough for the Mass Market

On June 6, Xiaomi confirmed that every model in the Chinese 17T series, including the Pro variant, will pack a 7000 mAh battery. The company claims the new cell uses the highest silicon content in its history — 16 percent — and delivers up to 1.88 days of normal use. Wired charging reaches 100 watts, while wireless tops out at 50 watts. After 1,600 charge cycles, the battery is said to retain 80 percent of its original capacity.

That is more than a spec sheet improvement. By standardising the battery size across the lineup, Xiaomi is trying to sharpen the 17T's market positioning and address one of the most persistent consumer pain points: battery life without making devices noticeably thicker.

Should investors sell immediately? Or is it worth buying Xiaomi?

A Foldable Built From the Ground Up

The MIX Fold 5, meanwhile, represents a different kind of bet — one on vertical integration. The foldable will carry Xiaomi's third-generation in-house processor, the Xuanjie O3, built on a 3-nanometer process at TSMC with clock speeds above 4 GHz. It will also debut HyperOS 4 and the company's own large language model, MiMo.

President Lu Weibing said earlier this month that full ownership of the software and AI stack is the only way to maintain complete control over the user experience. Xiaomi has been investing in AI research since 2016, and its AI team has grown to more than 3,000 employees as of August 2023. The MIX line, originally launched in 2016 as a showcase for edge-to-edge displays, returns after a hiatus with an explicit goal of cutting dependency on external suppliers.

The economics behind that push are clear. Rising memory chip costs are squeezing margins in the mass market, but controlling its own chips and software allows Xiaomi to command a pricing premium in the ultra-premium segment — a crucial lever for its long-term vision of a unified ecosystem connecting smartphones, electric vehicles, and smart home devices.

Stock Under the Weather

None of this has moved the dial on the stock. The shares closed at €3.05 on Friday, down 2.37 percent on the day and 11.45 percent over the past month. Since the start of 2025, Xiaomi has shed roughly 32 percent of its value. The relative strength index sits at 37.2, underscoring the bearish technical posture. The 52-week floor of €2.97 was hit on June 5 — the day before the battery announcement.

The market's caution is understandable. Even as Xiaomi flexes its engineering muscle, the earnings slump raises questions about whether product innovation can translate into margin recovery quickly enough. The 17T series faces the challenge of converting technical superiority into pricing power and demand, while the MIX Fold 5 still lacks a confirmed launch date.

EV Push Adds Another Layer

Xiaomi is not relying solely on smartphones. On June 5, the group introduced limited-time purchase incentives for its YU7 electric vehicle, running through June 30 and including financing plans or an insurance subsidy. The EV business offers a second growth vector, but it also adds cash burn to a company already under margin pressure.

For now, Xiaomi is sending clear signals on multiple fronts: larger batteries in its core phone business, proprietary chips in its flagship foldable, and sales sweeteners for its electric vehicle. The stock, however, remains unimpressed. Until earnings stabilise, the 17T and MIX Fold 5 will need to do more than impress reviewers — they must prove they can lift demand at better prices.
