Bluetooth suddenly killing battery - Verizon Samsung Galaxy S6

Several days ago my phone starting dropping battery much faster than usual. While I am at work I barely touch my phone and some days I will only use 15% over an 8 hour period. This suddenly increased to about 40-50% a few days ago. I tracked it down to the bluetooth being enabled or not. My bluetooth has been always-on for the last several months without an issue. Now I can see the battery discharge rate increase immediately when the bluetooth is turned on. I've attached a screenshot showing the problem. I had the bluetooth off in the morning and you can see the slow discharge. I turned it on for several hours and you see the steep discharge until I turned it off again and the discharge levels out. It was not connected to anything during the entire day. Does anyone have any idea why this would suddenly happen? I am going to have to turn off my bluetooth when not in use until I figure this out.

Ugggh, the more I have this phone, the more I'm starting to dislike it. I'm having the same exact issue as you! I actually wiped the phone and it's been good for about 3 days, but just today I'm back again with BT killing my battery. Plus, now there's a new OTA today, but I don't know if I wanna take it since it may cripple the phone even more and maybe kill my chances of rooting one day (if OG5 is ever rooted). Tempted to sell this damn thing and go back to an S5.

Not sure if you're still having this issue, but I wiped the phone 3 separate times and each time it resolved the issue for a few days, but then randomly would start acting up again. I wear a Pebble, so disabling BT isn't really an option. Got tired of resetting, so I went to Verizon and a replacement is being shipped to me this week. Still not sure what the cause of the issue is/was since it was flawless for 6 months....

Pattern to my reboots - do yours have a pattern?

So over the last few days my phone seems to have settled into some sort of weird pattern with reboots. Although there are outliers, in general it always seems to reboot between 19-24h of uptime and nearly always at like 45 or 50 mins past the hour. It's the most bizarre thing in the world and why I think there's some funky software doing it. I don't have true random reboots, but I can't figure out what it is that is doing this. Very odd.
In all cases my phone is sitting with the screen off (I've NEVER had a reboot while using the phone/screen on) but it doesn't matter what radios are on, WiFi, BT, GPS (can be off or on).
Last time I ran "CatLog" a logging app from Market and had it write to SD logs and a reboot happened but it only by default writes every 200 lines so the last line in the file was probably not the last line in the log. I'm going to try again later and set it to write every line or few lines so I can see the last entry in the log before a reboot. Might shine some light on it.
Just find it very strange since it's a very stable and capable phone for about 18hrs and then it just craps on itself. Very strange.
finally. I too just think it is some weird software or driver bug because I was running EB 1.0.4 FINE for like 3-4 days and loving it... then it started resetting almost hourly. I didn't install any other apps past my initial normal set of apps.
Even CM7, seems like it is fine for a few days, then gets crazy. As long as I put a new nightly rom on it every day, it's good.
I didn't have any issues with stock though and didn't seem to have issues with CM7 for a while until lately.
The leaked GB rom causes lockups immediately out of the gate seemed hourly.
I use CM7 as my main daily driver now but I think you are on to something. We are talking about the Screen of Death right? I don't think mine ever reboots, but gets stuck at the lockscreen where the the display comes up, swiping to unlock vibrates then the phone but doesn't change screens to desktop. The buttons and click/drag widgets work even though you are looking the lockscreen.
I've never had my phone powered off in my pocket or noticed it "rebooting". Mine just has the SoD that seems to follow your pattern idea. They may be related. Stock roms may reset once it locks up, where CM7 just keeps running in its locked state.
I have a really strong sneaking suspicion that every G2X reboots but not everyone notices. Also if you naturually turn your phone off once a day or so you won't notice it perhaps or even a few days. The phone reboots pretty fast and the only way I've been noticing (except the times I see/hear it happen) is I have an uptime widget on my homescreen so it's obvious.
Same thing happened with my Droid Incredible btw...when it first came out there were all kind of random reboot issues. After a software update I would run that phone hard for 30-45 DAYS straight without a reboot.
It's annoying but I think it's just a matter of time before the G2X is the same.
I just hope that update gets here sooner than later.

I dunno. The tmobile jingle is pretty loud and I never hear it. CM7 has a silent one so possibly there but I dunno.
I use my phone pretty often and never had the suspicious that it reboots. My phone stays very cool during my usage compared to my nexus and other phones
My uptime was 4 hours since I reset it last. I'll monitor it with results. It'll be hard not to flash but I'll keep track and see how far I can keep it online.
i have not had any reboots or waking up to a dead phone ....with the only fix is a battery pull.... ever since I started.
1) my over night charging / long term charging to 100%... only on the LG charger that it came with. Only short term...maybe. less than an hour and not to a 100% charge on a non LG charger (car charger etc...)
2) I restart my G2x every morning when I take it off the LG charger..(after I take it off..I did it once while on the charger and had an issue... (there is definitely an issue related to when it charges to/ around 100% charge)
Just my 2 cents.
Pattern to my reboots - do yours have a pattern?
Hold Power and volume up simultaneously for about 10 seconds.
I've had my phone since Friday, but the only time I had the rebooting problem was this past Saturday when it rebooted four times within 15 minutes or so. Before the rebooting began, the phone had slowed down to a crawl, so I went ahead and rebooted it. After that, I sat it down and watched it reboot a few times on its own. Luckily my iPhone 4 owning co-worker was completely unaware of this issue since we tease and bicker with each other every day over Android and iOS .

I can guarantee that mine don't reboot. I've had it up fire days, checked the up time and play with it constantly.if it rebooted in the middle of the night I would hear it or the uptime would be close to zero in the morning..
I have a way stable phone.running stock, rooted with bloat removed.. I love this damn stable phone.

What bloat did you remove? I've removed most but not all of it. Can you list it?

Everything other than smart share, tegra zone and qik. Of course have nova and need for speed also.
Oh also have car home froze..
Maybe jumping the gun here but I tried to let mine go as long as it could without resetting it. I kept tabs on it and it was running awesome the entire time (#33 CM7).
Last time I noticed my phone on was like 17:33:xx hours. I had like 44% battery left. Next thing I know the phone is off. I tried turning it on and a battery icon flashed and turned back off.
What I am thinking is that perhaps the faulty battery driver is telling the phone that the battery is dead and preventing it from booting up. We were talking in another thread and I said something that really makes sense: If the battery driver tells the OS that there is 0% battery then it will just reboot. The battery itself may have a 50% charge left. That would explain the random reboots too (the battery driver telling the phone there is 1% left and cutting power). Maybe a hard reset semi-corrects the problem but eventually resets again due to false information.
My weirdness/powered off occurred right around 18hours. The phone could have just died too.
Almost need a Voltmeter so someone can test the battery (or however it can be tested).

Yes I know the battery driver is part of the problem as can be seen on CM7 builds but what's odd is my time varies so for a long time it would reboot every 17-20 hours, now all of a sudden it goes to 36 hours before it usually reboots. Looking at logs it doesn't appear to throw any major errors before a reboot which implies that it's a a kernel panic or low-level fault. At this point I've given up on trying to find the issue since it's been repeated over and over that T-Mo and LG are releasing an update. Might as well enjoy the phone and wait for that to come out
Amen. Just keep flashing CM nightlies and you'll never worry about it.

[Q] Problem: phone dies randomly, sometimes for days...

Hi all,
I would really appreciate some help with my issue on the HTC One S. I've been looking for a solution for weeks now and still don't have a clue on what it could be happening.
The PROBLEM is this: sometimes my One S turns off suddenly. Next, I turn it on but it is very likely to do the same again in a few minutes. If I am lucky, it turns on and works for a while (which can be from hours to days), but if I'm not, the phone is completely dead (not even responding to charge and no matter how I try to boot it) for hours or even days. Finally, I get it again to life when I see it starts charging the battery (always from zero... even if it died at 80% battery).
I had a video on youtube to show you what it happens. What a pity I can't post it here cause of xda-developers rules!
Do you guys have any idea if this could be a battery issue/software issue or anything else?
Additional information:
-Glass is broken (phone works perfectly) but didn't have this issue for one month since the incident.
-Phone has been working now for 2 weeks (it will do it again... I'm quite sure)
-I dropped the phone into the snow a few days before it started to act like this, but dried it quickly.
Sounds like faulty battery or faulty battery connection. That would require opening up the device and either replacing or reconnecting the battery.
Thanks, it is always good to have a second opinion, two minds always think better than one
Just in case anyone else would like to give his opinion, this are other (maybe) useful symptoms: phone reboots in the middle of the night, or, if already turned off, it turns on (and off again sometimes) by its own. Also, sometimes, just before turning off, screen freezes for 1 or 2 seconds. The phone has its bad and good days (thankfully good days are more frequent as time passes), but, in its bad days, it turns off many many times and sometimes it doesn't even completely reboot, I just see first screen then nothing.
Also I have been using car chargers not from HTC in the same while the phone used to have this behaviour (like the Kindle car charger). Actually, once, while using one I bought on eBay, I got a message saying something like "phone has been disconnected from charger to avoid damage".
What could this mean? Battery fault can make this? I appreciate any similar experience or opinions
Bateries are durable now days, I'm afraid that the snow got into your phone and caused a short circuit on motherboard.

Rapid battery drain on Samsung Gear S3...about 50% per hour at times!

My S3 Frontier was a problem child when I first got it a year ago. It would never stay connected to my phone, and all I did was tinker with it and reset it over and over again for months. I was ready to Ebay it when the Tizen 3 update was pushed. Since that time, this watch has worked great, up until now. About a month ago I got new iPhone. I had a LG V10 Android phone and was a little concerned that the iPhone would mess up the watch. The Samsung app on IOS was a bit limited, but it still worked fine. About 2 days ago, the watch all of a sudden started eating up the battery. It went from 100% to 31% in about 3 hours Tuesday morn. I charged it over night, and yesterday it was fine. Today it was OK up until an hour or so ago. It went from 71% to 17% in just over an hour. I was not even using the watch. I have wifi on auto, the display always off, brightness on 6, heart rate monitor off, and no 3rd party apps installed. All I use the watch for is to keep me alerted when I get incoming texts, weather alerts, and it tells me to get up off my arse sometimes and move! I do not use it to make or answer calls, GPS and location is off. Up until now, when I would put the watch on the charger when I went to bed, the battery would be at 70-75%. I have about 20 or so watch faces all from the Samsung store and have uninstalled Facer and Watchmaker. I do not see how the watch faces could be causing this when the screen is off, but I do not know all the technical details on how this thing operates. The Samsung app on my phone does not show anything out of the ordinary running on the watch. Does anybody have any ideas before I rest this thing, or worse yet, chuck it and just go back to using my $10.00 Walmart watches!!? :laugh:
Won't hurt to try another factory reset before you retire it.
Same thing for mine was great then all the sudden drains battery like crazy.
I just did ANOTHER reset from the watch, and also removed and reinstalled the Gear app on my phone. Afterwards, did not install anything on the watch. It is still draining way too fast. This morn at 6 it was at 100%, after not using it at all, it is at 82. It is still setup as in my original post. The only thing I can think of that may have caused this was a small update that got pushed on it a few weeks go. Either way, I am tired of fighting it! I may have to contact Samsung, but I think it is out of warranty. If this thing gets the Tizen 4 update, I will give it another shot.
I just thought of something. Is there a way to reinstall Tizen 3.0.0.2 again manually without hacking the watch or sending it back to Samsung? Maybe resetting it is not enough and it needs to to be wiped , then have the OS reinstalled.
I just started experiencing the rapid drain as well? Noticed it yesterday. Put the watch on at 7am and by 11am had the warning pop up that battery was at 15%
If you Google this, there are lot of folks having the same problem with this watch. I was just on a Samsung forum where several people were reporting this issue after the 3.0.0.2 update. The thing is, my watch ran great after the 3.0.02 update! Better than it did on version 2. My problem started after no updates. My best guess is another patch or the Tizen 4 update (assuming this watch will get it) may hopefully fix this. I am found no resolution so far.
I would say try a couple things. Turn Wi-Fi off completely. Mine gets hammered when I have it on in any way, and you COULD be seeing it poll like crazy in Auto. After testing that, I'd also try turning the BT off too (Just to test)
Mine started doing this two days ago and I made no changes (I always have Wifi off, heart rate once every ten minutes, AOD off, , no GPS, non-LTE watch). I usually get up to three days and now if I fully charge it by 9pm is't dead in less than 11 hours.
I have this problem as well, started yesterday. Looking through the apps, seems like s health is the one to blame! Before once charge was getting the phone still at 77% by the end of the day....
Same here, since a couple of days ago, Samsung Health draining the battery. CanĀ“t be a coincidence.
I guess it is possible the battery is going bad, but rechargeable batteries normally do not start losing capacity at one year of age, and it is normally a gradual process. I tried turning off wifi, and that did not help. Between 6 this morn and now (8.00 am) it went from 100 to 88% and all it did was show a few text messages from my wife. To add to my misery, the Samsung app just updated on my iPhone and now the program crashes whenever I open it and to go the Gear apps and faces. I can try reinstalling it, but it will reset the watch AGAIN, and I will have to start all over. If I was Bruce Banner I would be turning into The Hulk right now!!
son of a b!tch... i was hoping that it was a fixable thing, seems like its a widespread issue. Im having the exact same problem. started 2 days ago. Factory reset the watch and didnt even install any apps on it, just configured the watchface to diable the AOD and bezel wake. Its been fine for about 10 months and boom... utter failure. guess ill start a claim with samsung
Yes mine has worked great for over a year then all of a sudden 2 days ago it started going from 100% to dead in 3 hours or less.
sooooooo, i submitted my claim info on samsungs site and no more than 30 min following, my gear started turning its watchface on while on the charger very randomly. Did it about 6 times. Stupid coincidence? poltergeist? or are they digging into the device?

Same with my device. It started 2 days ago after a factory reset, goes from 100% to dead within the first 3-4 hours of the day.

I did not think of that! I am going to try that also!!
same here started 2 days ago, haven't changed anything ... they want us to get frustrated and buy the new galaxy watch!lol
I did a reset and a master reset then restored the backup, was good for the rest of the day after that.

HTC U11 Battery draining quickly

Need to know if anyone else has ran into this.... Among my family we own 5 HTC U11s (yep we really like it). Two of these were bought when it was first introduced so they are well over a year old. The rest have been bought over the last year. Recently ran into a problem with the very first one I bought, it ended up being my son's.
About a month ago his battery started draining very rapidly, lasting only about 15 hours; we normally would get a day+ without issues and still do on all other HTC U11s. We would charge it to full and without doing anything it would go straight down, in the battery info screen the graph would be a diagonal line down. We did a factory reset, still happened; cleared the system cache, still happen; did another factory reset and added no apps back, still happened.
Most recently we had the battery replaced (took it to CPR and they did it) and now the phone is back and it is still doing it. Right now it has no SIMM card, no SD CARD, and Factory Android on it without it logged in to any Google account so that it does not get any updates, and it is still discharging in about 15 hours.
Anyone else run into this, and know of a solution? I am a little nervous that the other phones out there will start having this same issue, so I am hoping there is a fix or something I am overlooking here.
The problem is the batteries and its historical. The more you use it the worse it gets and the replacement batteries have sat on a shelf for years only partly charged.
Time for a new phone.
Probably wakelock issue from Oreo update.
Try restarting your phone after you disconnect from charger; it works for me. YMMV

New Bluetooth device causing random restarts?

A couple days ago, my (OEM firmware) 3a started randomly restarting even when it was just idle in my pocket. The only thing that I had recently changed on it was to connect some new JBL Endurance Peak II true-wireless earbuds, which I used for a couple of activities. However, even doing a "Forget" on them didn't fix the reboots, so I ended up doing a factory reset and installing a subset of my previous apps to see if I could find the culprit. It ran OK for over 24 hours, so this morning I connected the earbuds again and used them for about an hour with no problems, then put them away. A couple hours later, my phone has just done a spontaneous restart again!
Does it make sense that connecting a BT device could do something like this? The buds are a new product where left & right can operate together or alone, so maybe something different there. Any ideas??
My next thought is to do another reset and this time wait for several days before reconnecting them, or maybe at that point I'll assume they're the cause and return them while I'm within the 14-day return window. Or maybe a newer phone (Pixel 5) might take care of it?
