CARLYLE, JULIANNA - On average, Daily Mode lasts between charges from morning to morning, which for some moderately heavy users includes the time spent in Extended Mode below 10% (Daily Mode will automatically switch into Extended around 10% unless the user opts out). Daily Mode will continue to be targeted for enabling the most features and daily charging.
When using Extended Mode from a full charge, battery can last up to 2 days and 2 nights. Extended Mode will continue to be optimized for enabling the must-have features and the longest battery life for a “still smart” Wear OS watch.
For Time Only Mode, we have run some tests on Carlyle and Juliana where the watch lasted over 30 days from a full charge. The watch will automatically go into this Time Only Mode at 3% (switching from other battery modes). While some smartwatch buyers may not be interested in a mode that turns off all the “smart” features, we found it useful to reserve a very small amount of battery for this mode, especially since the last 3% seems to drain at an unpredictable (often faster) rate. This way, instead of being surprised with a dead watch, you can at least see the time for a bit longer.
