I've switched from a FR45 to a FR945. The FR945 does not appear to be measuring stress and the body battery. Regarding stress, the watch is not measuring and recording periods of rest (even during sleep), stress often seems high (recording medium to high stress during sleep and periods of relaxation) and the body battery declined to 5% and has been 'stuck' at that level for 3 days.
I have soft reset the watch, removed the FR45 from connect and I have shut off the TrueUp feature.
The stress and body battery on the FR45 felt very accurate. Any advice to correct these readings on the FR945?
