Xiaomi launches Redmi Note 17 Pro Max globally with 10,000mAh battery at $499

Xiaomi has released the Redmi Note 17 Pro Max worldwide, featuring a massive 10,000mAh silicon-carbon battery, though European units get a slightly smaller 9,210mAh version. The device supports 100W wired charging, promising a full charge in 80 minutes and all-day power from just a 20-minute top-up, plus 27W reverse charging but no wireless option. It also boasts rugged durability with IP68/IP69/IP69K ratings and Gorilla Glass Victus 2 protection, though it runs a downgraded Snapdragon 6 Gen 5 chip compared to its predecessor.

Xiaomi's Redmi Note 17 Pro Max packs 9,210mAh battery for three-day use

Xiaomi has launched the Redmi Note 17 Pro Max with a 9,210mAh dual-cell silicon-carbon battery in Europe, and a 10,000mAh single-cell version in some other markets. The company claims up to three days of typical use or 37 hours of continuous video playback, alongside 100W wired charging that can fully charge the device in just over an hour.

Apple's first foldable, iPhone Ultra, expected at September 9 event

Leaks ahead of Apple's confirmed September 9 event point to a foldable iPhone Ultra launching seven years after Samsung's first foldable phone. Reports describe a nearly crease-free inner display, an ultra-thin body powered by the A20 Pro chip and a vapor chamber for cooling, and a liquid-metal hinge built on technology Apple licensed more than 15 years ago.

Samsung reportedly tested 7,000mAh battery for Galaxy S27 Ultra before scaling back

A Korean leaker claims Samsung built several Galaxy S27 Ultra prototypes, including one with a 7,000mAh battery and versions that dropped the S Pen to fit it. Samsung is said to have abandoned that extreme option, instead settling on a 5,700mAh to 6,000mAh target, possibly using silicon-carbon battery technology.

Fribin invests €1.5m in battery backup after Iberian blackout losses

After the April 2025 blackout across Spain and Portugal shut down its production lines and spoiled tonnes of meat, Spanish processor Fribin lost hundreds of thousands of euros in a single incident. The company has since bought two five-megawatt-hour battery storage modules, together worth about €1.5m, partly funded by EU Next Generation grants, to keep operations running during future outages.

Walk-On's Cuts Restaurant Size in Half to Speed Up Expansion

Walk-On's Sports Bistreaux, the sports bar chain led by CEO Brandon Landry, has begun opening restaurants roughly half the size of its traditional 7,000-to-12,000-square-foot format. A new 3,700-square-foot location in Atlanta generated $4 million in sales last year, and the company plans a similar-sized site in Birmingham as part of roughly 10 new openings targeted for 2026.

Researchers Build Quantum Battery That Charges Faster With More Molecules

Scientists led by James Quach have demonstrated a quantum battery that exploits 'superabsorption,' a collective quantum effect where molecules synchronize their energy absorption rather than acting independently. This causes the charging rate to increase as more molecules are added, defying the classical expectation that each unit absorbs energy at a fixed, independent rate.
