I have a Galaxy Watch 5 (bluetooth) and am very happy with it. I've got the sensors turned on continuously for heart rate and stress and it links to Samsung Health. The watch battery goes to about 65-70% after 24h from the previous charge.However, my wife has recently bought a Watch 6 (bluetooth). She is recently finding it does not last 12 hours on a full charge, (not always, but enough to be an issue). She also has the sensors turned on and it links to Samsung Health. I've checked the Wearables app on her phone and nothing stands out as unusual. AOD is not turned on, not using apps on the phone or maps. It's fully updated and running on a Pixel 7 Pro. I also went into recovery on the watch and cleared the cache.
Does anyone have any other suggestions, or could there be a fault?
Thanks
