Leaks point to a 7,200mAh battery in the Xiaomi 18. That is 200mAh more than the Xiaomi 18 Pro's 7,000mAh battery.
This would be unusual. Xiaomi's standard phones usually get smaller batteries than the Pro models. If true, the Xiaomi 18 could beat its own Pro version on battery size.
Xiaomi has not confirmed the battery figure. It comes from industry leaks, not an official listing.
Other Expected Specs
Leaks suggest the Xiaomi 18 will use Qualcomm's Snapdragon 8 Elite Gen 6 chipset. That is the same chip used in the Xiaomi 18 Pro. The Pro Max uses a faster Snapdragon 8 Elite Extreme Gen 6.
The camera could use a 200MP main sensor, matching the Pro series.
The display may grow to 6.4 inches. That would match the Xiaomi 18 Pro's screen size, and be slightly larger than last year's Xiaomi 17.
None of these details are confirmed by Xiaomi.
When Will It Launch
The Xiaomi 18 Pro and Pro Max already launched in China in September 2026. Xiaomi's president, Lu Weibing, has confirmed a global launch in November 2026. That launch covers Europe, the Americas, and the Middle East.
The standard Xiaomi 18 is expected to launch in China later, possibly in December 2026. Xiaomi has not confirmed this date. A global release would likely follow after that.
