The vivo-backed sub-brand is expanding its Z11 lineup. After launching the vivo iQOO Z11 Turbo earlier this month, iQOO appears ready to introduce two more models. The iQOO Z11 and Z11x have now secured network certification in China.
Tipster Digital Chat Station shared the certification details on Weibo. The leak confirms that both devices are moving through regulatory channels, which typically signals an official launch within weeks.

iQOO Z11: Battery Beast
The standard iQOO Z11, carrying model number V2551A, looks to prioritize endurance. Reports suggest a massive 9000mAh battery paired with 90W fast charging. That battery capacity rivals some tablets and should deliver multi-day usage for most users.
The phone is also expected to feature a 1.5K-resolution LTPS display. This panel technology offers a balance between power efficiency and image quality. A mid-range processor will likely handle the workload.
iQOO Z11x: Snapdragon Power
The Z11x takes a different approach. This model is tipped to use the Snapdragon 7s Gen 4 chipset. It's a solid mid-tier processor that handles everyday tasks and gaming without issue.
Display specs differ here too. The Z11x should get a 6.76-inch LCD screen with Full-HD+ resolution and a high refresh rate. LCD panels remain popular in budget segments for their reliability and lower cost.
Both phones target users who want large batteries and capable performance without flagship pricing. The Z11 Turbo debuted with premium specs including a Snapdragon 8-series chip. These new variants should slot in below that tier.
iQOO typically launches its Z-series phones in China first, with select models reaching global markets later. More specifications and pricing details should surface as the launch date approaches.
