Hi,
My watchface Blink measures the minutes in high power mode per day. Yesterday I got 62 minutes in high power mode. The days before was around 80 minutes average. Tonight my watch did update to 2.70 and at 6 am I got 262 minutes in high power mode. This means, the watch don't falls back to low power mode causing a high battery drain.
After a hard reset it is lower but not back to normal on 2.60 niveau.
