Bluetooth battery drain since 7.1.2 - Google Pixel Guides, News, & Discussion

This is crazy I've done so much to try and figure it out and want to see if anyone has ideas.
Factory reset countless numbers of times. Even tried not doing restore.
Replaced my device because I thought it may be hardware.
Been on stock, on most custom ROMs, and all the same.
On PN now and rooted.
Just installed Better Battery Stats but nothing from there yet. Will monitor.
It looks like BT share is always using the battery. I don't think it should be.
Any suggestions or ideas?
Yes I have some apps but nothing crazy and all the same as I had on 7.1.1.

Likely just a glitch. If the phone works fine just chalk it up to that.

Yeah it's happened to me a couple of times over the years after a full battery cycle it should be fine.

Anyone who is having battery drain on 4.3

Just an FYI -
I was having battery draining problems with my stock MK2 4.3 rooted. I had seen several forums with users complaining about the same thing. Long story short, I had messed up my phone trying to mod it and had to Odin a stock ROM. I Odin'd stock MJA, OTA updated to MK2 and re-rooted. The unexpected benefit to this was I how have outstanding battery life. I have absolutely no idea why this helped, but I figured I would share it so that it might help others.
I did pretty much the same thing you did and am noticing the same results.. Great battery life.. I had 4 hours of screen on time when it hit 5% last night ..Pics are of today's battery life so far...

Battery drain/ sudden shutdown

Hi just wondering if anyone else has had a issue with the battery suddenly having reduced charge. Over the last few days my wife has been complaining about her phone discharging in only a few hours. I thought an app might be causing it but I've looked and can't find anything that would cause wakelocks. Now she's complaining that the phone has shutdown after showing a 70-80% charge and then when it started back up was nearly empty. Has anyone else experienced this or can recommend a possible fix please? I'm going to try a factory reset when I get home from work but would appreciate any advise.

That phone has one of the faulty batteries.
Call Samsung and get a free replacement

factory reset after lollipop

Is it necessary to factory reset after lollipop update on my SM-G900H Galaxy s5? Because i havent observed any lags or battery drain (infact battery life has been pretty good) , but there is little bit of stutters here and there , and fingerprint scanner is taking a bit loong to recognize my fingerpint but chrome has been an a bit more sluggish after the update. So help me out as i heard people that it is mandatory as it clears old files, blah blah .

It's highly recommended, but if you're happy with the way it is running, it's not mandatory
For me, battery drain was a big issue before resetting, but there have been a few lollipop updates since then, so...
That's a very good battery backup I am never able to get more than 4 hour

Issues with battery life

So I've had this phone now for probably 3 months or so, but ever since I got it I've had some issues with the battery life in general, but it has only gotten worse by time and it's driving me crazy. Right now I'm barely even able to go through a day of using the phone without having to bring a charger with me and re-fill the battery, even with only 2-3 hours of on-screen time at most (no games either, just social media like facebook and snapchat etc.).
I've tried many steps to try to fix the issues, at first I tried to restore my phone using Samsung Smart Switch and that did not help resolving the issue. I've also tried to disable apps using Package Disabler Pro and I've also disabled GPS and NFC, but that didn't help at all. Knox isn't tripped.
Is there anything more I can do, or shall I just get it sent back for repairs?
Here's some screenshots showing off the issue:

To be fair, if you're in Marshmallow that's pretty good...
