Galaxy watch Battery life

[Greymire]

View attachment 293564GW46mm, BT version.
I did a full reset last week (The option to kill the Daily Briefing wasn't available where it should be, after the reset it was - although it took some time funny enough). So I disabled the daily briefing and all automatic messages from Samsung Health.
Since last Sunday I loose 10-15% battery life every day, which is the best I've seen so far.

The other settings are NFC off, AOD off, HR at frequent, automatic training detection off, Wifi on automatic, Location off, Screen activation by bezel off, I sleep with Good Night Mode on.

Before I put the watch on the charger yesterday before going to sleep, I was at exactly 6 days of battery life with still 13% left.

It was a quiet week though, no training done, no playing with the watch, a moderate amount of messages, but I am quite happy with the result.

Is deep sleep registering? I had to reset the prior watch to get it working

It isn't actually, but that is probably because the wrist band is kind of loose, prohibiting the watch in measuring my heart rate properly.
I will tighten the band and let you know.

I don't think the band is an issue. I got it working with my old watch after a full reset and time with Samsung support but it was still inaccurate. It would work one day, then not the next. And it was only getting a few minutes a night. Based on my old fitbit and reading about deep sleep I know I am getting more.

Ok, good to know. I don't need the watch to measure my deep sleep. Even if it was accurate, it would probably tell me something I already know. To measure REM and deep sleep you need to set the watch to Register REM sleep in Samsung Health. If I am correct that sets the HRM to measuring my heart rate continuously, which is a battery eater. I don't like that, or in other words: I sleep better without it

The always on HRM is not really a battery eater. While I am sure it may eat the battery a little quicker, I notice very little difference with it on as opposed to the every five or ten minutes (can't remember which it is). I think it uses more if you leave the range of your phone frequently and it searches. I got about four days with the new watch with it always on. My Fitbit Ionic was the same. Heart rate monitor had little effect. I use more getting board and playing with the watch.. Lol

I picked up my second Galaxy watch today. Worked on setting things up. Tomorrow will be day one for me.

Done a reset last week and battery life is even better than before. 3 days 21hrs so far with 1day 6 hrs left

 

[EMGSM]

I'm getting better batter life than I expected. I'm pretty sure this one is a keeper.

You have something on or something wrong with your watch. I don't lose that much all day.

 

[Caller24]

Is it anything to do with using apps not written fot this OS?

 

[Ken Allen3]

I've just got 4 days with mine and started charging at 10%. I had heart rate set to always, AOD not on, GPS off, wifi off, 2 workouts.

 

[EMGSM]

I'd say I got a solid 4 days which included one day where I was streaming music through wireless earbuds during a 30 minute workout. I started the 5th day with 17% but I don't count it as a day.

I have the 42mm LTE. I just got it last Tuesday and have yet to get a full day out of the battery. My S3 was wayyy better. I'm thinking about returning this one.

I would seriously consider returning it and getting the 46mm version. That 472mAh battery is lasting me 3 to 4 days. NumberSync on, GPS on, HR frequent, location on, lots of notifications for email, texts, weather, Amazon, Slick Deals, etc. and no power saver use. Keep in mind that this use is with the watch within BT range of my Note8. I haven't tested Standalone mode for any long duration. When using my S3 Frontier LTE, I was only getting around 36 to 40 hours.

I had trouble with my first 46mm and returned it for another. Now I get three days fairly easy. I still pmay with it a lot. It will probably improve when the honeymoon is over. You could try a full reset (using buttons, not in settings) first. Just backup everything prior. What are your settings? Are you using DND and Goodnight mode while sleeping? Notifications seem to be big drainers. You probably know that since you had another Samsung. I turned off most notifications.

My 42 mm bluetooth will fo 14 hours and still be 85 percent.

Battery life seems to be quite an important issue for many. There seems to be some sort of unofficial contest to see who has been able to squeeze the most life out of a full charge. The motivation for some seems solely to be to accuse Samsung with fraud over claimed battery life!! ;-)
But I pose the question - ultimately is “5 days “battery life really that important? As long as my watch lasts a full day (and night) anything else is maybe a bonus ! I accept there is a convenience factor to not NEEDING to charge it daily, but as most of us sleep next to a plug sticking it on charge once a day to top it up isn’t really a huge problem is it?

Which kind of brings me to the point of this post. Whilst max time between charges is an admirable goal maybe the importance should be place on maintaining the long term health of the battery. There is quite a lot of information in various technical papers available regarding this battery technology, but in summary. Deep discharge cycle i.e. Routinely letting the battery drop to <10% and charging it to 100% is not good for the long term life of the battery.

The suggestion is maintaining the battery between, say 70 – 90% charge will ensure the battery will last the maximum amount of time before replacement is required. It is all ultimately related to what stresses the battery. Deep discharge and maintain it on charge at 100% are the worst” stresses” or so research indicates.

Personally I seem to have implemented this charge strategy without really thinking about it. I just stick my watch on charge whilst I am having a shower and breakfast so leave the house every day with the watch at , say, >90% (100% if I have an extra cup of tea).

I guess if in 5 years my battery is still able to retain a decent charge when all around have died at 3 then you could argue it has been worthwhile. I guess time will tell.

I feel 36 hours should be minimum. You want a full day plus a work day so you can charge in the evening before bed. At just 24 hours you are trying to rush a charge in the AM or charging at work. That's, fine if you are an office worker but impractical otherwise. Look at Garmin and what they get?

I should add sleep tracking is major for me so night charging is not an option. In fact I can only give Samsung a bit longer to improve sleep tracking or I get a band or use Sleep as Android which will kill me because it drains the watch line you would not believe. I have had sleep issues and health issues for awhile so sleep tracking is needed. I may end up with a dedicated sleep tracker but want to avoid it if possible.
