Just a short report on battery life. Had to leave my SW2 at home for a week. It was powered up but not connected to the phone and just laying around.
After a week it still has 50% battery left. Pretty good I think.

I noticed that when connected but left lying around the watch enters a sort of sleep mode where the watch face on the screen is turned off. Usually when not wearing I turn my SW2 off but I wonder how much effect this sleep mode has on the battery & if the watch still continues to receive notifications?

Yes it receive notification unless you close your BT connection in watch to reduce power. In this state (BT off) I used 2% in 8 hours last night.

My watch is fully charged at the beginning of the day, 5:00 am, and 12 hours later it is down to 39%. I checked my notifications and did use the internal music player when working out for 30 minutes today. So was just wondering what everyone is experiencing with battery life.
Think I can get 24 hours with the screen always on and wake up gesture set on. 2 days with wake up gesture on and always on screen set off.
70%@24 hours with wake-up gesture, moderate heart rate monitoring, NFC and Wifi turned off, and lots of notifications.
Wonder why my battery is draining so fast...
I'm at 70% after an 8 hour work day. Wake up gesture on, wifi, bluetooth on.
After a day I get home with 33%. By bed time I am closer to 28-29%. No way could I get 2 days. This is with brightness low, although ambient still working. Gesture on, wifi & bluetooth on. This is the biggest disappointment about the phone.
Can I get through a day? yes. Can I get the claimed battery life? no. I do not get many notifications (maybe 15 emails and 10 texts a day on it).
Currently at 65%. Last plugged in was yesterday morning at 6am. WiFi off since its always near my phone. Wake up gesture on. Brightness at 6. I get a good amount of notifications too. This can easily last me 2 work days.

Mine was at 62% last night so two days won't be a problem. Since it's new I'm still playing around with it and using more battery than is necessary. Put my wife's photo on the watch face just to see if I could. I did shut off WiFi since my phone is always nearby and NFC since that doesn't really work yet and I'm not sure I would use it anyway. I also turned off the turn on with notifications. Accidentally put it in a waterfall pond this morning doing some maintenance and am glad I don't have to worry about that aspect of it.

With brightness at 7, all connections on (WiFi, BT, NFC), screen always on, and receiving notifications, I finished yesterday with about 20%. The watch was taken off the charger at 6:45am and put down around midnight.
Today, I made one change and turned off WiFi. Watch off from the cradle at 6:45am and right now at 10:36pm, I have 31% left.

Last night I was at 33% again (10:00 pm). I turned off the functions wifi/bluetooth/nfc and this morning I was at 20%. I am running it down today to see if that will help condition the battery (100-0 then full charge) and if it adjusts how the percent remaining is displayed.
I seem to remember that batteries should be usually kept between 20% and 80% with an occasional full cycle to help keep them conditioned. I'm no expert though so this may or may not be true.
29 hrs and it shut down. Light use of the device.
-30 email/text notifications.
-15 hrm tests.
-screen brightness of 5.
-22hrs with wifi/bluetooth/nfc on,
-8hrs with it off (during sleep).
61% left last night. 60% left seems to be my average. NFC off, WiFi off, watch on with notifications off, heart rate frequent. Basic watch-face with white background and date. Notifications from ESPN and texts.
Ending 18 hour days with about 35% in the six days I've had it. Brightness @3. BT and wifi on. Nfc off. Always on screen on. Tilt to wake, and heart rate off.
Decided to try the always on feature today and ended the day at 31% instead of my usual 60% so this feature uses a lot of battery. Going back to not always on.
With the s2 classic, im at 38% with light usage, a few notifications, wifi off, nfc off, wake up gesture on and 50hrs and 22 mins off the charger.
Edit: brightness on 7.

Varies a bit from what I can see. I took it off charging dock at 6:30am. At 3:10pm, I have 82% left. Always On screen disabled, brightness at 6, WiFi, BT, NFC on. First day, it was worse.
That is extremely weird. Just bought mine. Charged it fully through night.
- Picked it up at 06:15 @ 100%
- Wifi on, NFC, on, HRM Frequent.
- Brightness 7
- Screen always on
- Wake up on notification
- Wake up gesture on
Battery at 14:00 = 5%....
is this normal ??
Hi,
I have the s2 classic and I love it. I have read on CNET that they were able to get nearly 3 days of battery life before charging. I can't get 24hrs of usage before charging. I have changed the brightness to 5 (the screen does shut off and is not on the always on mode), I shut off wifi and NFC . I am not using it all that much, what is everyone else getting on average? I just want to know if I might have a lemon.
Thanks

Hey @APT-ART , You can't try to turn off the automatic heart sensor for longer work on battery. Also the black background (pure black, so pixel are not lighted at all for that part of the face) will help to improve it.
For me it depends on how many notifications there are during the day, what applications I am using and how I charged it last time (I recommend to clean both the back part of the watch and the wireless charger as well). Also for some faces the brightness level of 2 or 3 should be enough to use it as a normal watch WiFi on but NFC off, also the automatic heart sensor turned on but less regular setting.
The battery stands for me for about 30 - 40 hours. But for the first two times I've got only about 16-18. Just let it discharged to 0%, then charge it to 100% without turning on. Good luck!
I keep my brightness at 3, keep always on watch face turned on, tilt to wake off, heart rate off, wifi on, nfc off, S voice watch face listening off, get probably 50 notifications per day and after a 16 to 18 hour day have about 40 to 50% battery left.
I think S Voice watch face listening, higher brightness, and tilt to wake (especially at a higher brightness) does the most damage to battery life.

Really good tip, I am going to let the watch discharge to 0% and see what happens. thanks! :good:
With very light usage I can easily get 3+ days. I turned off nfc and WiFi. I left on the heart rate scanning. I use it as a stand alone watch at work since I can't use my phone. I have the brightness at 3 and ambient display off / tilt to wake on. Not ideal usage for some, but it's a good setup for me.

I'm assuming everyone here has the non 4g version and that's why you guys are getting pretty good battery life. Got my S2 yesterday with 4g and fully charged overnight. Took off charger and about 8 hours later the S2 is at 38%. Not happy but going to try that discharge tip. To see if it helps. Also may have to tweak some other settings. I had the Gear S 4g and it didn't drain that much. I can usually get a days worth out of it.
you need several cycles to really know what kind of battery life you can expect; one days worth wont tell you a thing
How do you change the heart sensor setting?

You can change it by going into the s health settings on the watch. Options for auto heart rate are frequent, moderate, or off. These settings are separate from if you actually go in and start and exercise. I have my auto turned off (to conserve battery) but when I go in and actually start an exercise session on the watch, it will monitor heart rate. The auto heartrate is just for random monitoring throughout the day....having it set to off will not impact monitoring when you start an exercise.
I purchased a GS3 3 days back and using it with my OnePlus 5. Although everything is fine - except for the meagre selection of apps in Tizen store :crying:
I am facing an issue with irregular battery drain. When the watch is in standalone mode and Airplane mode on, the battery level drops at a steady level till 50% - after that the drop is very very fast - maybe 5% every 30 mins even though i am not wearing it. I went to sleep with 23% t 11PM and at 6AM the watch is dead. AOD is off as well. What might be the issue here? Please advice

For the last few weeks, I've noticed that most days my watch won't stay on all day. It will just randomly power off and when I try to power it back on the screen will light up with the start up screen and then go back off. When I get home and put the watch on the charger, the battery is rarely dead. In fact the lowest I've seen the battery when I've put it on the charger is around 46%. So, why does my watch just arbitrarily turn off (and not come back on) when the battery is clearly not drained? Anybody else experience this issue?
Hello there,
This is my 1st post, and I'd like to contribute by posting this small sheet that I've been making, basically tracking battery life, what was it used that time, when it was charged and etc...
Would like to know if you guys had similar, better or worse experience with it, and your thoughts about it too.
Cheers.

I use the GW4 classic 46mm. To improve battery life, I have wifi off, bluetooth on all the time, rotate wrist to wake up off, tap to wake off. I wear my watch to bed, and it isn't turned off until I get home from work, typically around 5:30 pm to 6:00pm, then back on around 10-11 pm for bed.
I'm getting 3 1/2 to 4 days of battery life, using it like that.
I was getting around 1-2 days at most until I turned tap to wake and rotate wrist to wake off.
I'm in a repair business, turning a screwdriver all the time, which was hampering battery life.

So what I'm gathering you aren't using sleep tracking, how about some HB measurement and stress?
and btw, will try to disable rotate wrist and wifi, and will write down the results in same sheet
I use GW4 classic 42mm LTE version. I turn wifi off, bluetooth on, esim auto switch on when phone is not connected, in SS Health I set HR every 10min, stress set to manual. For the watch to wake I turn on every option (wrist, tap and rotate bezel). After work at around 6pm I turn on airplane mode, and I don't wear it while sleeping.
With all of that my GW4 lasted for around 1.5 to 2 days

I use the heart rate monitor and sleep tracking. I had the gear watch frontier and I started tracking my sleep & heart rate at night. I noticed my heart rate was spiking 2-3 times at night in the 90bpm range. On a yearly check up with my doctor, I mentioned it. Had a sleep study done. Mild to moderate sleep apnea. Been on a CPAP for 3 years. Now, my sleep heart rate stays in the low 50 to upper 50 range, and I sleep through the night if I don't have too much liquid in the evening.
