Third-party reviews

What we like about vivo Y21 (4GB + 64GB)

  • Excellent battery life with a 5000mAh capacity that can last up to two days for regular users
  • Sleek and modern design with a premium-feeling glossy finish
  • Slim, lightweight, and ergonomic build that is comfortable to hold
  • Reliable physical fingerprint scanner integrated into the side power button
  • Good daylight photography with vibrant colors from the primary 13MP camera
  • Strong durability; some users report the device survives multiple drops without cracking

What we don't like about vivo Y21 (4GB + 64GB)

  • Weak performance for gaming and heavy multitasking due to the aging Helio P35 chipset
  • Low screen resolution (HD+ only) which lacks the sharpness of Full HD displays in similar price brackets
  • Poor low-light camera performance with significant noise and loss of detail
  • Standard 18W charging speed is relatively slow for a 5000mAh battery, taking roughly 2 hours for a full charge
  • Lack of 5G connectivity, which may limit future-proofing
  • Pre-installed 'bloatware' apps in the Funtouch OS can be a nuisance for some users

Verdict

The Vivo Y21 (4GB + 64GB) is a budget-friendly smartphone featuring a 6.51-inch HD+ IPS LCD display and a slim, lightweight 8.0mm design. It is powered by the octa-core MediaTek Helio P35 processor, coupled with 4GB of RAM (plus up to 1GB extended RAM) and 64GB of expandable storage, running on Android 11 with Funtouch OS 11.1. A significant pro is its large, long-lasting 5,000 mAh battery with 18W fast charging and reverse charging capability, which can comfortably last a full day or more with moderate use. The phone also features a 13MP dual-rear camera system, an 8MP front camera, and a convenient side-mounted fingerprint sensor. Main cons include an average processor not suitable for heavy gaming, a standard 60Hz HD+ display resolution (lower than some competitors), and the lack of NFC connectivity and IP water resistance certification.
