The Fitbit Versa 4 offers a battery life of about five to six days without the always-on display enabled, which is comparable to the Fitbit Sense 2[1][3][6]. However, when the always-on display is activated, the battery life drops significantly to around two to three days[1][3]. This is a common trade-off for smartwatches with always-on displays, as they consume more power to keep the screen active.
In comparison, the Apple Watch, which also features an always-on display, typically lasts about 18 hours on a full charge, though some users report longer battery life depending on usage patterns[2]. The Apple Watch's battery life is notably shorter than the Versa 4's, even with the always-on display disabled. However, the Apple Watch offers more comprehensive smartwatch features, which might contribute to its shorter battery life.
Garmin smartwatches, such as the Forerunner series, often provide longer battery life, with some models lasting up to two weeks without always-on displays[1]. The Garmin Fenix series, for example, offers extended battery life, especially with solar charging options, but these models are typically more focused on outdoor activities and may not offer the same level of smartwatch functionality as the Versa 4 or Apple Watch[5].
Overall, the Fitbit Versa 4 strikes a balance between battery life and smartwatch features, making it a solid choice for users who prioritize fitness tracking and don't need the full range of smartwatch capabilities. However, for those seeking longer battery life with always-on displays, other options like Garmin might be more suitable.
