What we don't like about Samsung Galaxy Watch 3 45mm

  • Significant decrease in battery life compared to the original Galaxy Watch, often requiring daily charging
  • Limited selection of high-quality third-party apps in the Tizen OS store compared to Apple Watch or Wear OS
  • Slow charging speeds, taking over two hours to reach a full charge
  • Highly restricted functionality when paired with an iPhone, such as the inability to reply to messages
  • Bixby voice assistant is often described as slow or less capable than competitors

Verdict

The Samsung Galaxy Watch 3 45mm is a premium smartwatch featuring a 1.4-inch circular Super AMOLED display (360x360 resolution) protected by Gorilla Glass DX and a functional rotating bezel for navigation. Powered by the Exynos 9110 dual-core processor with 1GB of RAM and 8GB of internal storage, it runs on Tizen OS 5.5 and includes advanced health monitoring such as ECG, SpO2, and fall detection. Main pros include its classic stainless steel or titanium build, high-quality leather straps, 5ATM/IP68 water resistance, and highly intuitive tactile controls. However, notable cons include a relatively short battery life of approximately 1.5 to 2 days, a limited selection of third-party apps compared to rivals, and restricted functionality when paired with iOS devices.
