The Battery Specifications article adds Auto 40+ hours (30+ with Always-On Display), which is stored as 40 with the plus sign here. Days are converted to hours exactly. The 17 and 15 hour music rows do not state the display setting. The store FAQ calls the 45 h figure MAX GPS with dual frequency, which conflicts with the spec table and the battery article, so the spec table is followed.6Maker product pagesupport.coros.com/hc/en-us/articles/23476623096980-Battery-SpecificationsRead 14 October 2026PACE 4 Pro table: Auto 40+ hours (30+ with Always On display), All Systems On / High 60 hours (45), Dual Frequency / Max 40 hours (30), daily use with Sleep Tracking + Daily Stress 21 days (7 days with Always On display). Actual consumption can be higher with backlight, navigation, weak signal and accessories. The Auto row has no always-on option in the schema, so only the 40 hour figure is stored.
