I wanted to give it a little more time to see if anything changes. I still love this watch! It typically takes less than two hours to charge to 100% and takes 3-4 days to charge. Wonderful. All gadgets work too. Steps, heart rate monitor, phone with stress monitor and messages work very well. Although it was her first watch and has been refurbished, it is her best in my opinion. I had an original Samsung charger, that might make a difference too. My Gear 3 that I returned never charged properly and held a charge for about a day and a half. I'm checking this early so I'll do an update if anything changes drastically. I've previously bought a refurbished Gear 3 and a lot of things were just plain wrong: it took forever to charge and then charged for less than a day. My pulse, normally around 62, fluctuated between 79 and 189. Sleep was indeed disturbed. I would have a deep sleep sitting in a lounge chair. So I returned it. So I ordered the updated Samsung Galaxy. I believe this was Samsung's first watch, so some hiccups would be expected. Not on this. Fully charged in 1.5 hours. With the current tariff, I expect a charge of three days. Heart rate and sleep monitors are top notch. I'm amazed at the difference. At the moment it is a goalkeeper. There are many reasons to love this watch!
