Battery drain on forerunner 970 since SW update 12.70.

Over the past.few.days , my forerunner 970 battery drains much quicker. I had recently updated to SW.version 12.70. No setting changes on the watch. From full charge , battery drains rapidly over 3.or 4 days then.prompting for battery saver mode. Has anyone else experienced similar battery drain since the update?   

  • mine lasts 7 days (removed it during showers only), including 1 day rest, time in 'gps only' mode during runs 16hrs 24min (this week), pulse oxygen during night only, AOD off, brightness minimum (sufficent even in direct sunlight), battery remaining before charge 17%
