My girlfriend and I pre-ordere Galaxy watches 40mm and 44mm. We got watches on July 17, 2024. Yesterday I charged my Watch 7 twice... charged the watch last night, and woke up today with dead one. My 44mm Galaxy Watch 7 discharge in approximately 10 hours... in power saving mode, it shows 18+ hours of usage. UPD: - AOD - is off; - Hear rate - maual only; - Stress - manual only; - GPS - is off; - WiFi - is off; - Bluetooth - in on; - all aps cleared from the cache, no app is running; But it looses ~8% in 30 mins just laying on the table... My girlfriend has 40mm Galaxy Watch 7 and right now it has 45% and shows 20h 20 mins left in normal mode and 1d 9h in power saving mode... Online support member told me that for the first time every device battery might gets drains fast so please check for some days. I do not think this will help, but I will try to wait. They also suggested to reset Watch. I just did it, will se if it help. My old Galaxy Active 2 hold battery better than brand new Watch 7. It's dissapointing...
