Galaxy 7 Watch - lights on

[CeeCee12345]

The lights (all of them) on the back of my Galaxy 7 watch seem to stay on all night. If I loosen the watch away from my wrist for a moment, they go off, but then the next time I wake up (I wake up a lot 🫤), the lights were back on. It seems to be draining the battery. Should they be on constantly? 

Thx! 

 UPDATE: The lights came on at about 2:45am. I redder to get them off. They came back on at about 3:10am and have been on constantly ever since. It is now 8:33am. This cannot be normal.

The lights will stay on all the time on the back of the watch while your wearing it that’s the sensor’s measuring your data.

But they are not always on. This seems to only happen at night. Every other watch I've had has taken periodic measurements, not constant measurements 24/7. This one has all three lights on flashing all night.

You notice them at night because it's dark. In the daytime, the ambient light dims the infrared. The lights are on when the sensors are active, so it would depend on what you were tracking as to how long they stay on. I am not sure that they are actually on all night (or all the time), but when you wake up and move around, they certainly come on. I'm sleeping, I don't notice the light, but when I get my middle of the night wakies, the light goes on when I move my arm. Your battery will drain during the night, because the watch and sensors are in use, not because the lights are always on. If you are tracking sleep, you need to make sure you have more than 30% power. Giving the watch a boost in the evening is not a bad idea. Also using the battery at night is the backup function, which will not happen if you do not have 30%.

Sadly, samsung has designed a watch with really great features that are unusable due to the deficient battery capacity. I had to turn all of the sleep functions off, otherwise my battery won't even last a day. My fitbit watch performs way better than this.

The battery life is really not meant to be more than 24 hours. Less depending on how many vobrations from notifications you get, calls you make and receive and a whole host of other factors. It's meant yo be charged every day. I don't believe people who say they get up to 3 days of battery. The only way that's remotely possible is to have it in watch only mode. My watch is perfectly usable for all features. With a full charge, with my usage patterns, I'm good for 23 hours and some minutes. In the late evening about an hour before bed, I check the battery level and if it's below 30%, I give it a boost til it's iver 50%. I have no problem with this, as I grew up in the era if spring driven watches, and had to wind my watch every day. I don't know what you were expecting as far as battery life, but if you are vetting 15-20 hours on normal usage, the watch is functioning properly. Small watches have small batteries. And you fit it foes not have all the featutes snd sensors of the watch, do it's a baseless comparison.

That's interesting, because when I reached out to samsung support, they told me it should last 100 hours. If course, that depends on what you have running on it, but 18 hours is nowhere near 100. I mean, really, with just steps, heart rate, and a few notifications, I still do not get a full 24 hours. That is just a really poor design.

I have never gotten more than 24 hours out of the battery life. I have the watch 4 for 2 5-3 years now. Battery life used to be a bit better and inexplicably went down after I switched to a new phone, but I think that has more to do with the way the remote connection works. I'm used to it now. Even when the battery life was better, I still put my watch on the charger every morning. The only difference in my routine now is the exta charging boost before bed.

I do the same with my Watch4 - charge it up in the morning and then again when I get home from work. I don't use it for music or calls, but do track sleep and use SPay and some app notifications and use of Gallery and Timer and every 10 minutes HR.

That's basically my useage, except for my swim and I put the watch in airplane mode for that, since cell, BT and wifi do not penetreate water and the watch uses a while lot if energy trying to find the signal.
