What we like about Unihertz Jelly Star (8GB + 256GB)

  • Extremely compact, pocket-friendly credit-card-sized design
  • Surprisingly powerful performance for its size with the MediaTek Helio G99 processor and 8GB RAM
  • Includes features rare in modern flagships like a 3.5mm headphone jack, microSD slot, and IR blaster
  • Full Android 13 support with access to the Google Play Store and NFC for payments
  • Transparent back with customizable pulsing LED notification lights
  • Affordable price point (around $200) offering high value for money
  • Excellent tool for digital minimalism by naturally discouraging excessive scrolling

What we don't like about Unihertz Jelly Star (8GB + 256GB)

  • Small 2,000mAh battery often struggles to last a full day with moderate to heavy use
  • Tiny 3-inch screen makes typing difficult and can cause eye strain
  • Camera quality is poor in low-light conditions and lacks detail
  • Lacks 5G connectivity, limited to 4G LTE speeds
  • No official IP rating for water or dust resistance
  • Poor long-term software support with few security updates and unlikely OS upgrades
  • Slippery, rounded body can be difficult to grip without the included case
  • App scaling issues and small text can make some third-party apps hard to use

Verdict

The Unihertz Jelly Star is an ultra-compact, credit card-sized 4G smartphone running Android 13, featuring a 3-inch LCD display, a powerful 6nm MediaTek Helio G99 Octa-Core processor, 8GB of RAM, and 256GB of internal storage. Its main pros include its extremely portable form factor, a versatile programmable side button, the inclusion of a 3.5mm headphone jack, NFC for payments, an IR blaster, dual-SIM support, and a unique transparent back with dynamic LED notification lights that make it a great conversation starter. Key cons are its small 2,000mAh battery which can struggle with heavy use, average camera performance in low light, lack of 5G connectivity, no official IP water resistance rating, and the tiny screen size may be difficult for users with large hands.
