I decided to document battery usage on my gear2 after initially running into some trouble with the battery. I bought 2 brand new gear2's and when they arrived, I connected one to my note 3, which has a custom rom, and the other to a s5, with a stock rom. I noticed right away that the gear connected to the note 3 was draning battery much faster. This is what I set out to troubleshoot.
First of all let me explain the issues I had between the note 3 and the gear2 that was causing the battery drain; these are likely due to my rom being custom. When I first attempted to pair the gear to the phone, it would say device not supported. To even get the gear paired I had to use titanium back to remove anything that was related to the gear manager or gear in general. I then reinstalled the latest gear manager apk from the samsung store. This did not go smoothly and I had to find some missing apks as well because the app kept crashing. I didn't document exactly how I got it working because I was just trying any and everything to get it working. I know for sure that I was missing samsungservice apk and that was causing the app to crash at one point.
Once I got it paired up, I noticed when I would boot the phone "sensor service stopped" would show up. Also, when I would open s health multiple "health service" and related services would say that they stopped. I had to remove each one of those services with titaniuim backup and then reinstall the latest s health and let s health reinstall the services I removed. Sounds complicated and most likely no one will even run into these issues, but I posted this just in case. Also, I left "sensor service" uninstalled and it doesn't appear that s health reinstalled it and everything is functioning without it as of right now.
As long as gear manager is functioning correctly and there are no error messages from s health and everything is updated, there should be no abnormal battery drain. The following are some scenarios that I documented to show what normal battery drain should look like.
First thing I did was charge the gear up to 100% and let it sit overnight, for 8 hours while I slept. I disabled bluetooth so it wasn't connected to the phone, I also went to recent apps and made sure all programs were closed and that all sensors were disabled; sleep, pedometer etc.. After 8 hours of this I lost a grand total of: 1%. I woke up with 99% battery after 8 hours.
Next night I charged to 100%, connected to the phone via bluetooth, and closed all apps again and made sure no sensors were active and turned of notifications. After 8 hours of sleeping I had lost 4%. I woke up at 96% battery remaining. So the idle drain of just the gear by itself while connectd to the phone via bluetooth is half a percent an hour. Not bad at all.
Next I wanted to test how Tizen behaved with its apps. I read that some were getting better battery life by closing all apps down when not in use. I wanted to test this. So I did the same exact thing from the previous night except I opened every possible app as well. So bluetooth connected, no sensors active, no notications, but I opened every possbile app to load them up in the recent apps (memory). My findings were exactly the same as when I closed all apps the night prior. I lost 4% after 8 hours. So don't close out any apps, it does nothing on Tizen.
I next wanted to test the heart rate monitor as it was the single reason I bought the watch to begin with. Results were impressive. I turned the continual heart rate monitor on, running mode under exercise, and monitored my heart rate for 30 minutes (the amount of time I usually run in the gym). I lost 2% in 30 minutes. Not bad at all!
Next I tested one of the newer features of the gear 2 which was its ability to store its own music and play it back via bluetooth. I hooked up some bluetooth headphones and played continual music for 30 minutes straight. I lost 6% in 30 minutes. Thats 12% an hour. A little more than I'm comfortable with and it doesn't even sync with google music. It works very well, but just drains battery too much. Much better to use the media controller and have the phone play all the music.
For the final test I wanted to do a day of what normal usage might be like. I had bluetooth connected all day, notifications enabled, motion enabled (wrist motion to turn screen on), brightness at 2, I sent/responded to 10 text messages, received 25 or more notifications, 4 short phone calls, didnt use any monitors at all (heart rate, sleep, pedometer). I didn't play any music either. Ended up with 72% battery at the end of the day. At that rate I could have gone for 3 and a half days without charging. NOT BAD AT ALL! My gear 1 would come nowhere near that number.
Anyway I hope this may be beneficial to people struggling with battery life or considering a gear2 purchase because Of battery life. I know for me personally, battery life is the reason I returned the gear 1.
Nice testing and information but I don't see any conclusions about why the one connected to your Note 3 had worse battery life other than its custom ROM. Did you try swapping watches to the other phone and running the same tests? Did you restore the Note 3 to stock and get those results?

Sorry I wasn't clear. I was getting drain when I first was able to get the gear connected to the note 3. The gear manager app and s health were both showing different errors and crashing though, so that was the reason for the drain. Once I fixed s health and gear manager the drain was on par with the other gear. If those 2 apps are screwed up and crashing or showing errors it will keep sending/requesting info from the gear or something which kills battery.
thanks a lot for your info
i really hope we gonna have a good app to see what is eating our battery...
really strange that in tizen they don't have it ...
I downloaded the recent upgrade on my gear 2 and the battery life significantly reduced from 3 days to <24 hours! I switched off bluetooth and somehow it improved to 1.5 days. Something with the latest is caused my Note 2 to constantly ping the gear2 watch.

I have the same gear manager but I am still on the stock ND8 and am not having any issues. Maybe try to flash back to ND8 if possible. There may be an imcompatibility somewhere. NDD is made for devices of other countries, so who knows.
I am based in the Philippines. Just today I got another upgrade on my gear 2 to BNE5 and still the unusual draining continues. Must be the GM app?

Clear data on the manager app and start from scratch. If that doesn't work we may have to uninstall the app completely and start over. That's what I had to do.
Guys, have a look at this thread. Could be applicable to Samsung devices as well...
Thank's

Hello there,
I am using my Note Edge (N915FY) since 2 weeks. Nowadays I got my Gear S and sync'ed them together with bluetooth. But since them I have a very very terrible battery life on my Note Edge. Its draining very fast every 2-3 minutes 1 percentage is gone.
I looked with BetterBatteryStats and there is sth wrong with my Bluetooth services I guess. There are too much wakelocks and it prevents Deep Sleep.
This statistics is for 4 hour standby mode on Note Edge. I didnt use it, it was just in screen off position.
BlueSleep: 4h 6m
msm_serial_hs_dma: 4h 6m
msm_serial_hs_rx: 1h 56m
bluetooth timer: 34m
During this, screen time was maybe just 20 minutes or sth like that. I didn't even use my Note Edge or Gear S during the whole 4 hour.
When I turn off Bluetooth everything is fine, but after I turn it on it is again like this.
I have tried disconnec/reconnect Gear S, and the battery out&flight mode trick on my Note Edge. Nothing helped.
Please help me, how can I fix this issue?
Please, no body has got any idea? I tried the ART mode, Dalvik mode, wipe cache, wipe dalvik,...
Nothing helped me. I cannot use my Gear S. It eats my battery very very much.
I hope to get a solition here on xda.
And i really dont understand is here just me with this kind of a problem on Note edge + Gear S combinated use? Isnt here any other user with this two devices which uses with aame problem or wothout any problem?
Thank you very much...

I have the same combo. I am not seeing the battery drain you are. However, when I got my Edge last week, I noticed all my texts from my S5 all the sudden showed up on my Edge, several hundred. I did not restore messages, but when I looked at battery stats, ATT Message Backup to Cloud was using 25% of my battery. It was nice to have all my texts show up on new phone, but I DIDNT REALLY NEED IT WITH THAT DRAIN. so, I FORCE STOPPED AND DISABLED att cloud message backup, and my edge now has 40% or so after 10 hours. My Gear S is out of blue tooth range a lot due to my job, but it reconnects instantly when in range. And when out of range, it connects remotely.
So, I have the same setup as you, but ATT, and I do not experience the drain.
I have the sprint variant of the Note Edge. And I just got the LG G Watch R a few days ago. But I'm not getting any unusual battery drain.
I have the T-Mobile Note Edge and the Gear S and do not have any battery issues. However, since there is no point in having the watch connected via bluetooth all the time, my situation is different. Bluetooth is for file transfers, app installs and data syncs (S Health). Unless I am missing something, there is no other reason to have it connected via bluetooth. Unless I am using a headset, I have bluetooth disabled all the time. That is why I wish they would put a bluetooth toggle in the status drop-down.
I'm having the same issues with my Gear 2.
bluesleep, msm_serial_hs_dma, bluetooth_timer, and msm_serial_hs_rx all keeping my system from going into deep sleep. I end up with 95% awake and 5% deep sleep most days. Has anyone found any fixes?
Uninstalling all Gear related apps from Titanium fixed the problem for me, but then I can't use the Gear so that kinda defeats the purpose.
I had a similar issue.
Updated the firmware for the watch via Kies and the gear manager app. All been fine since.
I've been running latest firmware with all the updates, so that doesn't seem to be the cause for me :/

Only other major battery drain is Unified Daemon for me (that associates with the watch)
I bought my Gear s2 a couple of days ago and although it's working fine and giving me excellent battery life, my phone's battery life has become terrible. I used to get to the end of the day with 70% left but since I've installed the gear app, that's become 20% or less.
Nothing else has been installed in this time. I don't want to return my watch so can anyone please help?
Same here lots of resets and refreshes decided to just get a rapid car and desk charger for work !!!
Do you have location enabled (in the gear app) ? I would imagine that could do it. I have a oneplus one and don't notice a huge effect on mine.

I didn't notice any difference at all with my battery life on my S6 Edge (Verizon) which was surprising because before I never turned on bluetooth - and not it is on 100% of the time.
After the latest VZW update to the phone, battery life has been crap (for my son's too, and he doesn't have a smartwatch/use bluetooth).
Espn app was killing my battery.

Settings, individual app settings, weather, use location (is it enabled? Or refreshing too often?)

It was turned on. Hopefully that will make a difference!
After 7 hours of being off, it's made no difference to the phone's battery life. Google play services and Android system seem to consuming a fair chunk of battery (7% each approx), but that's about it.
Guess I'll have to factory reset the phone and start re-installing each app to see if something else is responsible..
I was having the opposite: my waych battery was getting killed. The fix was to uninstall the gear app in my phone and to a reset on the phone. After reinstalling everything now all is working fine and my battery life is great

Yup, I can confirm that this works! Battery life much better now on the phone!
Some apps are poorly coded and misbehave with Bluetooth always on. My phone battery was draining quickly too after I got the watch cause now Bluetooth is always on. In the battery stats Gasbuddy never showed up but I could see that the phone was always awake and never went to sleep. After some googling I found out that gasbuddy can misbehave. I uninstalled gasbuddy app and it's back to normal.
Hi guys,
I have just recently switched to 7 pro like a few days ago from my previous ROG2 phone.
The performance and also the screen is of course improved, however, im not feeling good with the battery and heat issue on this big boy.
I have a few apps running in background using location and all but these apps are the same setup using on ROG2. The phone seems to be heated quite fast, the temperature is around 38-40 degrees from what I check. This is from video call, listening to music via bluetooth. Not mention gaming on this one...
I'm sometime on 5G, most of the time are using 4G and WiFi.
Anyone facing this kind of problem and if so, how to solve it?
I already did factory reset though.
I don't have any problems with heat. I am not gaming so can't say anything about that.
Also while chargin the phone doesn't get hot. But I am using slow charging.
I am at the moment restricting the 5G signal and seems like everything else is much improved, both heat issue and also the juice draining is much slower.
Gonna keep doing the same thing for another week and see the result.
I am also using schedule charging and only maximize it to 90%.
Interesting. I only casually have 5G so can't say anything about that. But it would be absurd to have a more expensive SoC because of 5G capability but being unable to use it because it overheats and drains your battery flat.

Here same problem, issue drain. Terrible stand by and I Get some drop frames on genshin impact, problably is a bad optimization on kernel.
I have heat when watching Netflix and hbo Nordic. Hope next update fix those
Interesting. I have insane/superb battery life (better than my Mi 10T pro) and no heat at all.
I've had mine for a few weeks. Did notice it getting heated up during basic browsing and light usage. I charge mine to 80% and it usually lasts a day, though I would've expected it to be much better than that considering it is a 5000 mAh battery.
I got a Galaxy Watch for Black Friday. The watch battery life has been okay and gets me 24h battery life. But the Galazy Watch4 Plugin on my phone has been destroying my phone battery life.
I have a Pixel 6 Pro and before the watch I would end the day around 20-30% battery life. Since I got the watch I'm out of power by 9-10pm. I've tried uninstalling everything and reinstalling, also reset the watch but same issue.
I'm not really sure what else to do at this point. Everything is basically default settings, I have no idea why it's draining my phone so much.
Have the same problem with this plugin in S20FE Qualcomm. Uninstalled all plugins, galaxy wear app and restored watch to factory settings and it seems to improve the problem a little bit. Still getting 1hr less SoT than usual just for the watch. It is not good at all!
Its not showing up at all on my Pixel.

You have a Watch connected in Bluetooth all day, receiving notifications, calls, and more.
What did you except ?
Bluetooth only is a big drain.

Eh, not as bad as I've been getting. It was 22% drain for me the other day, another was 24%. After deleting cache and storage and reinstalling the gear app. My old fossil and the ticwatch pro 3 I had did absolutely not drain the battery like this. The other one I see is Samsung health. ~9% drain daily. Samsung needs to do something about this for sure.
FYI, pixel 6 pro. Less of a drain on my pixel 4xl though. Not great either.

The same problem exists on S22 Ultra oddly enough. You would think it wouldn't be an issue with Samsungs own devices. The plugin doesn't show on regular battery stats but gsam shows high usage for the wear app. Uninstalling "Galaxy watch4 manager" was the fix for me but means going without the cool watch. Same issue reproduced on OnePlus 10 Pro. Attached before and after screenshots of battery drain with and without the plugin
Guys, try to disable battery optimisation on all the apps related to watch, ex. wearable, plugin, etc. I had this issue with my OG galaxy watch and I read somewhere that by keeping the battery optimisation on for these apps, the phone trys to stop them but the apps switch on again and this cycle goes on resulting in battery drain, I have OnePlus and I disabled the optimisation and the battery was back on track with minimal plugin's battery usage
Hope it helps!
Bluetooth draining the battery is absolutely not the issue. I have had Galaxy watches for well over 5 years now. The app has never drained the phone until the last month. The Galaxy Watch 3 plugin is accounting for 40-60%of my battery drain on my Galaxy Pixel 6 Pro. I turned off battery optimization for the app to see if it helps. I just hope it doesn't take much usability of the app away.
I'm having the same problem to.
Didn't have this issue before.
Did anybody find a solution?
Cheers.
