Mystery iQOO Z12 Phone Tipped to Feature 10,000mAh Battery and 7-Inch Display

Smartphone manufacturer iQOO is rapidly expanding its upcoming Z12 lineup, with recent supply chain leaks pointing to a new mid-range device engineered around a massive 7-inch display and an unprecedented battery capacity exceeding 10,000mAh.

According to prominent technology tipster Digital Chat Station, this mystery iQOO handset has officially entered the moulding stage, meaning its physical dimensions and core form factor are now locked in. Tentatively scheduled for a mid-2027 release in the Chinese market, the device pushes the boundaries of standard smartphone design by prioritizing sheer screen real estate and multi-day battery endurance.

While the exact marketing name remains unconfirmed, industry speculation strongly suggests the device will debut as the iQOO Z12S. This aligns directly with the brand’s established hardware strategy. The preceding Z11 family heavily emphasized battery capacity, featuring the standard iQOO Z11 with a 9,020mAh cell and the iQOO Z11S equipped with a 10,000mAh pack. A capacity exceeding 10,000mAh makes this upcoming model a natural successor in the “S” tier.

This newly leaked behemoth joins a growing roster of anticipated Z12 devices. iQOO is reportedly preparing the performance-focused Z12 Turbo for an imminent launch in China, while simultaneously developing the iQOO Z12x and iQOO Z12 Lite to target mid-range consumers in the broader global market.
