Update for this morning:

Brought my charger to work today to recharge the watch and do some testing.

1. I turned off automatic updates in the Gear app on my phone.
2. I reset the phone and did not restore any backups (I don't use anything that wasn't on the phone or store music or any other personal content on it.

My watch is the non-LTE variant and I set the following options:

• Notifications (in Gear app): all off except Calendar, Clock, Facebook, GMail, FB Messenger, Google SMS app, Phone, and Phone Services
• Samsung Health HR to every 10 minutes, no activity detection, Inactivite alerts off.
• Brightness to 5, Auto Low on, timeout to 15 sec, AOD off, Wake-up gesture on

So far, after 2 1/2 hours, it appears to be discharging normally at about 1.6% per hour. This is somewhat higher than my usual average consumption of about 1.2% per hour over the last year but given how it's been the last couple of day (almost 9% per hour!) I'll take it.

Thanks, I will give this a shot, The HR monitor was set to frequent.

I can leave for work and come home 12 hrs Later with around 70% battery. I charge it to 100% and wear it to bed. Last 2 mornings it was at 30% when I woke up 7 hrs later.
Gonna try a reset to factory and not do the updates.

[pappy35]

Data so far: 38% in 24 1/2 hours (1.55% per hour). I'm going to call this resolved for now.

[srayjacobs]

I deleted the downloaded watch faces and that is making a difference, but still not right.

[Scott Currence]

Mine seems to have fixed on a simple restart.

Interesting. My Gear S3 started having severe battery drain 2 days ago also. It continues to have problems with sporadic fast battery drain. I did a full reset of the S3 and re-paired with phone. Seemed ok, until today. Very fast battery drain again.

I'm not sure if the watch received an update or something. But something isn't right... all of a sudden.

I have

Thank goodness for this and other forums. This problem is a Samsumg issue. Somehow a common core app or the watch firmware was updated and is now causing fast battery drain.

My concern is that this issue will damage the battery (deep discharges) before a fix is issued.

[srayjacobs]

Many Gear S3 owners on Samsung’s forums note the bug, with their batteries draining far quicker than usual with no obvious cause. Samsung’s forum moderators also can’t seem to pin exactly what the cause is, but some speculate that it could be due to an app. Currently, though, Samsung is aware of the issue, but has no timeline on a fix. The company says that a “future update” will solve the problem.
That was on google news

I started having the issue yesterday. Down to 10% in a little under 6 hours.

I read in the XDA forum about factory resets and decided to take a step further by doing this:

1. Hold in the power button in until 'Rebooting...' message.
2. Repeatedly press power button until boot menu shows.
3. Press the Home button until 'Recovery' is selected.
4. Press and hold the Power button until restart.
5. Set up watch as new watch not restoring backup.

After doing this, I'm down to 83% in 8 hours. This is with me playing around with it for about 20 minutes installing apps and changing settings.

Just over 2% per hour.

On Monday morning I noticed the same problem. During the day the battery is discharging normally. Over night is when I am noticing a 70% drop. I'm turning it off tonight so as to not further run down the battery until a fix is identified. I typically have DND on at night. Gear S3 classic.

[WalkingHorse]

I find that it is something that is happening overnight. I put mine on DND before bed and place it on the charger as I always have. When I get up in the morning I shut it down (not reboot) and then turn it back on. This stops the new battery drain bug for me.

[racedog]

My drain also seems to always happen at night. I wear my watch for sleep tracking and it is going Fromm 100 percent down to the low twenties.

Last night it did not happen for the first time in days. We'll see what happens today and tonight.

[pjwk81]

Mine started the other day too. Went from 100% to 15% in about 90 minutes. The next morning I charged it up to 55% and it turned itself off within 10 minutes.

Have Samsung said anything about fixing this and is it definitely now pinpointed to Samsung Health?

[bbgpsuser]

I had same issue crop up suddenly. During the day it would just gobble the battery. A couple of nights ago, while I was sleeping and wearing the watch in DND, the battery went from 100% to 23%.

Following the leads out on the internet, I confirmed that in Settings -> Apps -> "Samsung Accessory Service" was using A LOT of battery.
1. I went into the storage tab for "Samsung Accessory Service" and cleared the cache.
2. I deleted the "Galaxy Wearable" app.
3. I restarted my Gear S3.
4. I reinstalled the "Galaxy Wearable" app. It walked through reconnecting and resetting the Gear S3.

After that my Gear S3 battery use has been very low. It has been a day or two now and it seems that the problem is solved for me.

[Harplayr]

Same issue here. It's improved somewhat after deleting Samsung health, doing a reset, but still not where it was.

[banggang01]

There are numerous reports on the Samsung Support forum of Galaxy 'Gear' watches suddenly losing battery endurance, mine included. Symptoms are loss of 100% charge in less than 12 hours that started a couple of days ago. I haven't made any changes at all (no settings changes, watchfaces, apps, etc.) nor have there been any software updates that I'm aware of.

Anyone else out there having this problem? Perhaps another N7-Gate-like disaster?

Delete the Wearable app. I believe that was the problem not Samsung Health.

Well, more than a year after the last post, my s3 classic has started with the draining of the battery. It’s a “Amazon renewed” which is supposed to have battery equal to at least 80% of new. Initially, I was getting over 2 days between charges. I’m guessing there’s an app running wild. Trying a reset to see if I can figure it out.

Never ever buy used and returned, or "renewed", as the Amazon third party scammers like to call them.... they are pallet bought junk. I bought 4 "renewed" items in a row that were someone else's returned garbage.... didn't work of course, returned them immediately and only buy new on sale now. My wife's recently been down the same road, except her last couple devices limped along for awhile like yours before dying... so she's finally decided to listen to me lol. Your "renewed" watch battery is dying....learn from this and move on But definitely try a factory reset before you completely write it off though.

[Roosterman]

The good thing about "renewed" is there is a 90 day return window. I did the reset and fully charged it. Wore it last night to track my sleep. 8 hours later, the watch was at 15%. I then checked the battery usage and S Health used 47%. Not sure how to slow that down.

[Roosterman]

OK, my problem has been rectified. After the reset, I started to get overwhelmed with updates for the watch. Not sure why after a month of having it the reset triggered it but not before. Initially, I thought all the updates really messed it up. The watch that day was basically unusable. It wouldn't go into apps and took forever each time I tried. Then, all of a sudden, it started to function correctly. Battery life has been really good. This morning I still had over 30% left after 45 hours off the charger. I'm really pleased with how it's working now.
