I have a 44mm Active 2 bluetooth & I've noticed a significant drop in battery usage last night. My watch was at 11% & I put it in sleep mode because I charge the phone in the mornings not overnight. I woke up finding my device was on for only 1 hour after I fell asleep & placing it on the charger it charged for 4 hours till it was 100%. Odd. It use to charge in 1-2 hours. At 100% 4 hours ago now at 63%!?!? Before the Januarry 12th update I could go 3 days of working out & using the smarthings app multiple times a day before charge. After update. It wont even last half of tomorrow. I say we complain if the ECG functions mess with battery more. This is why I bought the device. Not to beta test samsung batteries.
