- Potentially less efficient
vivo iQOO Z7x
- Blazing-fast 80W charging
- More efficient chipset (Snapdragon 695 6nm)
- Likely improved image processing
- Modern design
- Slightly lower peak performance than Z1x
- May have slightly less RAM in some configurations
Display Comparison
Both phones likely feature similar display technology (likely an LCD) with a high refresh rate (likely 120Hz) for smooth scrolling. The Z7x might have slightly improved color accuracy due to advancements in display technology since the Z1x's release. Screen sizes are likely comparable, around 6.6-6.7 inches.
Camera Comparison
Camera specs are likely similar, with a primary sensor around 64MP. The Z7x may benefit from improved image processing algorithms due to its newer chipset, potentially resulting in slightly better image quality, especially in low light. Both will likely offer decent but not exceptional camera performance.
Performance
The iQOO Z1x holds a slight edge in raw CPU power thanks to the Snapdragon 765G. However, the iQOO Z7x's 6nm Snapdragon 695 is more power-efficient, leading to better real-world battery life despite the potentially lower peak performance. Gaming performance will be good on both, but the Z1x might handle more demanding titles slightly better.
Battery Life
This is where the iQOO Z7x truly shines. Its 80W wired charging is a game-changer, allowing for incredibly fast top-ups. The Z1x's 33W charging is considerably slower. Both phones likely have a similar battery capacity (around 5000mAh), but the Z7x's efficiency and faster charging make it the clear winner in this category.
Buying Guide
The iQOO Z1x is a good choice for users prioritizing raw processing power and are less concerned about charging speed. The iQOO Z7x is ideal for those who value fast charging, improved power efficiency, and a more modern chipset, even if it means a slight performance trade-off.
