The Xiaomi 17 Max just cleared China's 3C quality certification under model number 2605EPN8EC, following its earlier SRRC wireless certification. Two mandatory certifications cleared means one thing: this phone is ready to ship. Xiaomi has confirmed a launch before the end of May.
The back-screen is gone. The battery is enormous.

Key Points

  • Xiaomi 17 Max (model 2605EPN8EC) cleared 3C certification — coming after SRRC approval, both mandatory steps before China retail availability are now complete
  • 8,000mAh battery confirmed — the largest in any Xiaomi-branded smartphone ever, excluding Redmi models
  • 100W wired and 50W wireless charging confirmed via Digital Chat Station — a full charge from empty takes roughly an hour at 100W
  • The secondary rear screen from earlier prototypes has been dropped — the saved internal space went directly to the battery
  • Snapdragon 8 Elite Gen 5, 6.9-inch flat 1.5K OLED, 200MP main camera, and periscope telephoto — late May China launch window confirmed

Two Certifications Down, Launch Ready

SRRC handles wireless certification in China. 3C covers electrical safety and charging standards. Both are required before any phone can be sold legally in the Chinese market. Clearing both in quick succession signals that mass production is either complete or nearly there. For context, the Xiaomi 17 Max's SRRC filing came in late April — the 3C approval following within weeks is a textbook pre-launch certification sequence.
Late May is the confirmed window. The specific date hasn't been announced but Xiaomi's own signals are consistent.

8,000mAh — What "Largest Xiaomi Battery Ever" Actually Means

The Xiaomi 17 Pro Max ships with 7,500mAh — already a strong endurance device. The Max adds 500mAh to that while also running a larger 6.9-inch display. The silicon-carbon battery chemistry that enables this capacity without proportionally increasing weight or thickness has been Xiaomi's key battery development focus for two generations.

The 3C certification confirms 100W wired output — a figure that means a phone of this capacity still charges in under 70 minutes. Fifty watts wireless adds genuine daily flexibility. The combination of 8,000mAh capacity and 100W charging makes endurance a non-issue rather than a compromise.

Why Dropping the Back-Screen Was the Right Call

The secondary rear display that appeared in early Xiaomi 17 Max prototypes was experimental — a feature that consumed physical volume, added weight, and drained the main battery. Removing it freed up enough internal space for the 8,000mAh cell while simplifying the design. The result is a phone with a clear, singular identity: large screen, massive battery, flagship processing, improved cameras.
The 200MP main sensor and periscope telephoto sit above the standard 17 Pro's camera system without matching the Ultra — the Max fits cleanly in the lineup between Pro Max and Ultra.
China first. Global availability timing unconfirmed.
