What customers like about vivo iQOO Z7x (12GB + 256GB)

  • Extremely long-lasting 6000 mAh battery that can last all day, even with heavy use.
  • Very fast 80W wired charging (advertised 1-70% in 34 minutes).
  • Smooth and strong performance for daily routines and gaming (e.g., PUBG, ML, CODM).
  • Good, stable display (6.64-inch IPS LCD with 120Hz refresh rate).
  • Expandable storage via a dedicated or hybrid microSD card slot.
  • Features an IPS display, which some users prefer to avoid potential burn-in issues associated with other types.
  • Includes a 3.5mm headphone jack.
  • 5G support across various networks.

What customers don't like about vivo iQOO Z7x (12GB + 256GB)

  • Camera quality is considered decent/average but not great or spectacular for photo enthusiasts; it's a standard camera, nothing special.
  • The display brightness is relatively low (around 450 nits), making it difficult to see clearly outdoors in direct sunlight.
  • No 4K video recording support.
  • May experience noticeable heating when gaming or pushing the phone hard.
  • Some users report faster battery drain after updating to Android 14.
  • Comes with some pre-installed apps/bloatware, though they can often be disabled or removed.
  • Lacks water resistance ratings.

Verdict

The vivo iQOO Z7x (12GB + 256GB) is a budget-friendly 5G smartphone that runs on the Android 13-based Origin OS/Funtouch OS and is powered by the 6nm Qualcomm Snapdragon 695 processor. Its main pros are the exceptional battery life from a large 6000mAh capacity cell, complemented by very fast 80W wired charging that goes from 1 to 70% in 34 minutes. It also features a smooth 6.64-inch Full HD+ IPS LCD display with a 120Hz refresh rate and a capable 50MP main rear camera. The primary cons are the use of a plastic build, the average quality of the secondary (2MP depth and 8MP front) cameras, which perform poorly in low light, the lack of an official IP rating for water/dust resistance, and some user reports of occasional overheating during extended gaming sessions or poor 5G reception.
