Just got the instinct 2 yesterday. On the latest firmware. After full charge battery was at 28 days. Then when I went to sleep it was at 27 days. Pulseox was not on overnight. Watch was in sleep mode overnight.
Woke up and watch was at 11 days. So it lost 16 days overnight? Percent battery was down to 94%.
I charged it to 100% and now it shows 21 days.
Maybe I just need to wear it for a few days for the the estimate to work itself out?
Try disabling the Bluetooth on the watch for the night. There may be a higher consumption if the watch repeatedly unsuccessfully tries to connect to the phone, for example when doing the nightly altimeter…
Tried it again last night. It was at 20 before I went to sleep. I had PulseOx turned on overnight too. So the first. Ight must have just been an anomaly.
Anyway. I'm good with things now.
Confirm that Pulse Ox isn't measuring at night and set to manual. That I could see causing the issue. Pulse Ox is the enemy of battery life.
