Amazfit Bip 3 vs Amazfit GTS 4 Mini
The Verdict
Both smartwatches deliver excellent value in the budget segment, running Zepp OS with SpO2 and heart rate monitoring. Display quality differs significantly: the Bip 3 offers a 1.69-inch TFT LCD at 240x280 resolution without always-on capability, while the GTS 4 Mini features a superior 1.32-inch AMOLED always-on display at 336x384 resolution that's considerably sharper and more vivid. Battery life is comparable, with the Bip 3 reaching 14 days and GTS 4 Mini managing 15 days. The GTS 4 Mini distinguishes itself with built-in GPS for standalone fitness tracking, newer Bluetooth 5.2 connectivity, and a premium aluminum case versus polycarbonate. Both weigh under 35 grams and share identical 5ATM water resistance. For $30 more, the GTS 4 Mini justifies its premium with substantially better screen technology and GPS functionality, making it the superior choice for fitness enthusiasts who value display quality and navigation features.
