Final Verdict
The iQOO Z11 5G is the more convincing pick if battery life matters at all. A 9020mAh cell is a massive advantage over the Z11S’s 4700mAh battery, and that difference will be felt far more often than the small gap between 165Hz and 144Hz refresh rates. Its display is also slightly larger, so it feels like the phone built for long sessions of video, browsing, gaming, and travel without constantly thinking about a charger.
The vivo iQOO Z11S still has its own appeal: 12GB of RAM gives it more headroom for multitasking, and some buyers may prefer a Qualcomm-based phone. But based on the specs here, it asks you to accept a much smaller battery for extra memory and a still-fast 144Hz screen.
For most people, the iQOO Z11 5G looks like the smarter everyday device. Choose the Z11S only if RAM capacity and Qualcomm hardware matter more to you than endurance.
