How is your heart rate if you don't mind me asking. You don't have to be specific if you don't want to be, normal, low or high would suffice. I've been having this issue to much frustration. My heart rate is high. Always has been. My resting is near 100 but during sleep can go down to 70. I get between 0 and 10% probably averaging 5%. Then I tried Sleep by Android which gave me seriously high deep sleep like 50 60%.
My interpretation which is just a complete guess is that it is based on a very simplistic algorithm uses your heart rate and bases it against a median equivalent of a proportion of the population or the average person or a sample and determines it off that, with nothing in place for outliers in the algorithm. I know when I'm well rested, and I'm not sure it's possible to have so many 0% deep sleep days without serious mental consequences. How long do you get before returning it is off the table?
What I found helped a tiny bit was to buy a microfibre cloth for polishing up the glass back before sleeping or after getting sweaty from excercise. Also buying a silicone strap with ventilation holes on it was a great purchase as the leather, whilst making the watch look like a real watch which is what I wanted, I found it was just not adequate enough to keep it firmly in place. My wrist is weird haha. I've compared it to my female coworker who has a Samsung watch and her wrist is more cylindrical in shape and mine very wide and oblong, oval, you know... kinda shape, lol. I'm certainty not suggesting your wrist should be a perfect circle but yeah I've went on a dumb tangent now. Silicone is just better for giving that form fitting snugness without the feeling that it's tight. No watch hole could give me a snug feeling with leather. Found one on Amazon for £7-8. The watch should stay in place when you shake your wrist about fast.
Maybe I was as advised this or dreamed it but it's better to use your left arm. It was maybe just good advice actually since prior to owning this smartwatch, I had never worn a watch so didn't realise how many times it would get in the way if you're right handed so I changed it over but I put a metal tachymeter ring on it early on to protect the front from bumps and to make it look more like a watch so in the early few weeks I saved it from a bump or 2.
Was advised to not wear it with the watch head against your inner wrist, it has to be on top about an thumbs width up from your wrist bone. And yeah I guess that's it. I was going to share the messages from the help centre conversations I had back from last year in case anything was of use but I can't find them. They will probably tell you to send error reports but I don't know how to send error report because how do you send an error over when when my watch isn't telling me there are errors. There is an option for sharing data for critical errors (or something akin to that) but I never get anyone from help messaging when I get really stupid results. For example, I rarely check my sleeping stats daily anymore, so when I looked last night I found this peach of a recording from a few days ago.
Don't be complacent like I was. If there is a new smartwatch announced at the upcoming Samsung event send it back. I bought it early on being being promised ECG and BP, I bought it for my health to motivate me as I stopped taking care of myself and it took 6/7 months of owning it or longer before getting it. But since my heart rate is constantly above 100bpm I'm unable to get ECG reports as it will give you an inconclusive result if over 100.
My floor counter never worked and all my personal bests are from years ago, the ones the health app gives me, and they're from before I owned a smartwatch and they are ridiculous anyway. I've climbed a few 3000ft mountains and one 4413ft mountain but it never had recognised it. My iPhone 6 was at least in the ballpark when I climbed a mountain, it would give me a figure of 300+ flights of stairs for a 3000ft for example.
You know what, I'm going to do something about this before the warranty expires. I was so preoccupied with so many concurrent horrible life event, many completely unrelated to covid, I let myself bury my head in the sand over this one for my own sanity. Thanks for refreshing my memory on this.
