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.
Almost a month since purchasing (Amazon return window coming up fast). Here's my experience given that I walked right into this battery-gate issue.
Disclaimer: I'm a heavy user. I get A LOT of email notifications, WhatsApp and keep the screen fairly bright (never less than 7 out of 10). It has Verizon LTE service. Verizon said this would not affect my battery life....
Week one. On a full charge I could only get about 5 hours. Off the charger 9 am and by 2pm it was back on the charger for a one hour re-charge that got me home until it was back on the charger for the night.
I had to purchase a second charger for my desk during the day. I picked up a third for $8 just to keep in my bag for when on the go.
Week 2. Same 20% drain per hour.
Week 3. I switched off diagnostic notifications, and switched from vibrate alerts to sound alerts. Big improvement. I went from 5 hours to about 9 hours. Battery drain is now 11% per hour.
Zero Lemon needs to make an S3 case...
And it needs a fast charging port. A Battery this small would charge quickly with a cord. 2 hours for 0% to 90% is pretty ridiculous in this era. My Note 3 charged to 100% in an hour 4 years ago.. And yes I know it's for waterproofing but other makers like Garmin and Polar use charging ports with waterproof gaskets.
I was getting about 2 to 3 percent per hour until a few days ago when the battery drain bug hit. At that time, it was almost 12% per hour.
I did a factory reset and I'm sitting at about 1.6 to 2 percent per hour.
I get about 1-2% but I don't need the fitness tracking stuff so i usually have Samsung health disabled and AOD off but location on and wake gestures on. I also have the diagnostic option off since the day I got it. I read somewhere the current battery bug can be averted by turning the diagnostic option off. I get 20+ emails a day and about 30+ texts and WhatsApp each. So I generally use my watch for texts, WhatsApp, emails, weather and Samsung Pay
With AOD ON and use for many things : cheklist, note, memo, notification, alarm, timer, stopwatch.... I have average drain of 3.5% at 4.5% by hour. I'm happy when I have 3.5% but it grow quicly to 4%-4.5% if I use a little. Just but can live with this.
For those who have serious battery drain on v3.0.0.2 (and even have broken sensors such as heart rate detection like me) can go for repair, if still covered by warranty.
I have recently the same behavior as described by many after upgraded to v3.0.0.2, battery drain 20%/hr and it become worse when I found out wake up gesture is not working at all, so is the heart rate sensor as well as steps tracker.
I hesitated whether to send it back to repair, but in the end so glad I did, it only took 1 day and they informed me they have changed the motherboard and replace with new battery (as I told them about bad battery drain issue as well). And guess what, I got back my gear s3 frontier with everything working but on old enough firmware 2.3.2.3 (which is working pretty good, just that battery usage around 5%/hr not that great).
After that I decided to take the risk to upgrade my firmware to 3.0.0.2 again, and whoa, everything still works perfect and battery drain has gone! Battery usage is now around 1%/hour which is acceptable I think.
Hi guys and one girl..
I have amazfit stratos watch and have two problems. When I have HR chest monitor my watch battery doesnt last long enough (it goes to 1 % in two-three hours, when I turn off HR monitoring it goes back to 30-40 %) and when i dont have chest monitor its PPG HR sensor is utter crap, useless, it would be better to not have it so I just turn it off. Please, what watch has better or good HR monitor and what watch has good enough battery for external strap HR monitor to last 6-8 hours with GPS ON.? if exist of course..
I am totally in love with my GW4 (Classic 46mm Model) as it's my first smartwatch but there is still one thing that bothers me, the unreasonable battery drain overnight. I charged up my watch last night, put the watch on my desk, came back in the morning and saw about 10% battery drain in 8 hours! That's insane considering the fact that I've disabled everything and even enabled battery saver, I thought after all these years I can finally get a full fledged Wear OS smartwatch and be happy with the battery but Wear OS is still the same OS as it was.
I've got the same issue. I thought it was the sleep tracking but I was wrong
And the funny fact is that the battery life is reasonably good when you actually using the watch, but as soon as you put it away it starts to drink juice weirdly, looks like there is no deep sleep kicking in no matter what, even disabling everything and enabling airplane mode.

Which version/size do you have? How many times have you fully charged the watch? I have Classic 46mm. My battery drains 4 -6 % during the night. I have watch on my wrist when I sleep. I always put watch into bedtime mode before I go to bed. I don't disable anything or put on power saving mode. I think the bedtime mode simply turns off notifications and stops watch face from automatically turning on.

Oh sorry for not mentioning it, It's the same as yours classic 46mm. I have the watch for almost 1 week now but I always charge it whenever it gets to 50% so it's a half cycle charge. Do you think I should let it fully discharged and recharge it for a full cycle?
I have the non classic 44mm LTE and I have always used bedtime mode and I've tried nothing all the way to disabling everything and enabling battery saver and still lose quite a bit at night

It seems to me that the battery lasted longer after doing some full cycle charges but I could be wrong. I definitely have seen improvement in battery life since the first few days I had watch. Not sure what it is.

How do you know it was not sleep tracking?
For me, I went to bed yesterday with almost 100% battery. The overnight drain was 15%, flight mode enabled, good night mode enabled and spO2 while sleeping on.
My watch is 40mm, BT modell.
Tonight I will try only the automatic good night mode.
What about Bluetooth when my phone is in airplane mode? Will it consume more battery searching for the device? My wifi will also be disabled in the night...
I am seeing this same thing
13% drain with airplane mode, good night mode, and battery saver modes on.
13-14% drain with battery saver mode and good night mode on.
This is for an 8 hour window.
Using the watch during the day, the battery does seem to last longer and I don't see the drain, even when using it to track workouts and such.
Last night my battery used 11%. I'm not sure what the difference is. I know I have been in the 4-6% range in the past but I always do not pay attention. Possibly related to how fully charged the watch is. Why do we think 10% is bad? I did a search on-line and I have to say that 10% seems very good compared to some other watches. The reality for me as that I'm typically getting 2 days plus on a charge unless I'm heavy on GPS. Currently I'm at 50% and I charged the watch 1 day and 9 hours ago. I came from a GW1 which had significantly more battery time but I'm still very happy with the GW4.
My drain is 20% overnight - despite watch being in bedtime mode.

If your watch is on your desk and turned on, it's constantly searching for your wrist. If you are not wearing it, turn it off.
I have the same issue about battery drain.
I lose between 15-20% each night with everything off (no SpO2, no snoring, etc)
I have the LTE 46 classic model
But based on people and comments I'm guessing the issue comes because I'm not using a Samsung phone and bed time is not synced with the watch and is still "online" all the night
Geez I thought my 3-5 percent drain was horrible. I have the 44mm Bluetooth only model. The first night it drained horrible but I had every sensor on. I noticed I got much better battery after disabling location. I've had mine paired since 7am this morning (it's now 3pm) responding to texts, wifi on and using Spotify on it at 75 percent brightness and it's at 79 percent now. Maybe I got lucky or something? The only sensors I have are the step counter as well as heart rate when resting more than 10 minutes and I never like to use battery saver mode on mine
Second night and I got about 20% drain overnight with everything turned on. I got a similar battery consumption like adj998. Spotify on first place.
I will try do disable GPS tonight and see if anything changes, but I guess it's a normal behaviour. One thing I could try is to turn the spO2 sensor off.
Read somewhere that unlocked ADB is the culprit. So I have unlocked it.
Let me watch how it helps my 20% overnight drain.

Interesting. I'm betting that this drain is related to certain apps as well. When I did my post yesterday about the 11% drain the previous night I noticed the Altimeter app was listed at 4.5%. I immediately uninstalled this app. I had used it once the previous day and apparently it was still using battery. Results: much battery time last night. I would say 3%. In fact, when I looked earlier this morning I still had 41% battery. Yesterday morning I was at 50%. 25 hours and 9% battery used. I have not been very active these last couple days (long days at work). Still putting in about 5,000 steps a day. I have notifications on (gmail, texts, meesenger), use bedtime mode, spO2 sensor off, and do not have watch always on.

Read on Reddit that altimeter drain was a known issue, in earlier models as well.
With people that are having excessive battery drain on their watch: are there any apps which are listed in Wear app -> Watch settings -> Battery that seem like a high percent of battery usage?

Actually yeah, for me it's Spotify. I installed it and connected it to my account but did not use it...
So far I have had no battery problems on my Galaxy Watch 4 BT.
Heart rate monitor continuously, display activated when the arm is moved, sleep mode from 10:00 p.m. to 6:00 a.m., medium-dark watchface from WatchMaker.
The battery is charged to 100% in the morning. During the day the battery is at 55-65% in the late evening. Then charging again briefly (to 75-80%) for a few minutes, until i go to bed.
Then sleep tracking takes place.
At the morning after getting up, I charged the watch again to 100%.
That was my routine at the last weeks.
On Sunday morning I had not much time, so I set the watch at 88%.
When i went to sleep at 11:00 PM, the watch still had 50%.
And here's the Problem:
The sleep tracking ends at 2:51 AM - the watch has gone off: the battery is empty.
Last weeks my Watch shows 2 d 14 h at 100%.
Today: 1 d 15 h.
This battery lost 1 day!
At this moment the battery is at 65 %...
WTF... Why?
What happened?
Everything was as always ...
Has someone an idea?
Something similar is hapening with me, I have watch 4 classic. I was able to push one day out of it, with an hour or so of exercise tracking at around 6PM and now all of a sudden from the past 3-4 days, I get battery low warning by the time I am done with my exercies, so basically I have to charge it for 10-15 minutes to get thru the rest of the evening and night. Forget sleep tracking, the battery is going down so fast it almost feels like if i glanced it at 1pm its at 70% and when I glance it at 1:05PM its at 65%. Extremely strange I hope there was not some background firmware update that happened.
My current endurance of Galaxy Watch 4 44mm is around 60-65h! Absolutely sufficient. Lots of notifications, step measurement ....
I turn on the display by tapping the screen.
PS: Before that I had a Fossil Sport, but after a year and a half the battery went down a lot and in time even though it was still 35% of the battery so the watch does resetovary.
Same problem here. I will try:
- Uninstall 2 apps (alberto's google assistant related)
- Disable location
- Restarted the watch
Reviewed battery drain app but no information about wich one is producing the draining. I detected most of the drain at night,next workaround will be try to disable some sleep monitoring function.
Last try, fabric restore...
I will tell tou about progress
