Fitbit Charge 5 Review Summary The Fitbit Charge 5 significantly upgrades the brand's popular tracker series by introducing a vibrant, 2X brighter AMOLED touchscreen display and a thinner, more comfortable design than its predecessor. It retains reliable 24/7 fitness metrics, sleep staging, and a 7-day battery life, while borrowing advanced health tools like Electrodermal Activity (EDA) stress scanning from premium Fitbit smartwatches.
