The always-on display (AOD) feature on the Fitbit Versa 4 primarily affects the device's battery life. When AOD is enabled, the watch requires more frequent charging due to increased power consumption[1][4]. This is because the screen remains active even when not in use, continuously displaying information like the time. As a result, the battery life is reduced compared to when AOD is disabled. For instance, with AOD on, the Versa 4 can last about four days on a charge, whereas disabling it can extend the battery life to nearly a week[2][5].
Beyond battery life, the AOD does not significantly impact other performance aspects of the Versa 4, such as processing speed or app functionality. However, it does influence how users interact with the device. For example, having the time always visible can be convenient, but it may also be distracting or too bright in certain environments, such as in a dark room[10].
Additionally, the AOD automatically turns off when the battery is critically low to conserve power[4]. This ensures that the device can still provide essential functions until it can be recharged.
In terms of customization, the AOD on the Versa 4 does not offer extensive options for personalization. Users cannot customize the display hours or content beyond enabling or disabling the feature[6]. However, features like sleep mode can be used to automatically turn off AOD during specific times, such as at night, to mitigate battery drain and reduce screen brightness[6][10].
