2.1 Blue Tooth Drain Issue ?? [6.35 Radio] - myTouch 3G, Magic General

Since the Transition from 1.5 to 2.1 no the 6.35 radio bluetooth, when enabeled has kept hte phone from going to sleep, the vattery drains very quickly as well as the Phone is Quite warm.
Example:
on a 2.1 rom with Blue tooth Disabled the battery will fall to 50% in 24 hours, With Blue Tooth Enabled the battery will fall to 25% in only 6 hours.
where as on a 1.5 rom the battery drain will drain at a less then noticeable pace weather blue tooth is on or off.
-------------------------------
When Bluetooth Is enabled:
* Cell Standby uses most of my battery
* Awake Time Matches the amount of time the Blue tooth Is on
I have looked at the possible causes with no Success:
* Blue tooth Transfer
* PairableTimeout in main.inf
are there other that are experiencing this issue, Has anyone found a solution, i would like to have my bluetooth enabled all day long again.
Does anyone know a way i can strip the settings for blue tooth so i cant pair or file transfer or anything, except have my phone connect to one blue tooth headset with minimal battery drain.

Bluetooth draining battery is known issue on new radio. I've messaged Sanpei about this and he is looking into it. It may take him sometime to fix this since he is a busy man
If you are like me that needs to use bluetooth, you will have to revert back to ROMs with old radio

no, you don't need to revert back to old radio
you just need to flash back stock rom
that's the only rom that doesn't have this issue

I confirm! I've written many times, but this problem has been ignored.
Read here: http://forum.xda-developers.com/showpost.php?p=6679745&postcount=1350.
Stevak.

Omg people, it has not been ignored, but the man that made this kernel has a life of its own jeez....

People U think that fixing BUGs is like "finger click" ? Deva are doing this for free in spare time ... Ehhh ... Instead of complaining to devs please complain HTC :/

@Krzysiec and Klothius.
You do not write so. I respect and appreciate the work of developers (including Klothius). They work very hard and seriously as professionals. I understand that they working in their spare time. They "steal" time in their lives and at their family. They do all this for free.
I thank them and I respect them because they entertain us.
In my post I meant that I (along with others users) have often written of the problem, but none (or few people) replayed. Some answers ignored the problem: "replace the battery", "reset battery status","switch off the radio" etc..
Only a few days the community accepts that the problem is real.
... and now... I think that Sanpei has solved the problem.
Thanks.
Krzysiec and Klothius... you forgive me?

I see that you're saying the problem is solved. Could you provide a link to the solution? I am having the same issue. Streaming to my stereo Bluetooth is draining my battery in no time. Would like to quit having to use the wired headphones again. Thanks.

Possible cause and solution to X10 Battery? -"No Sleep Bug"

Hey guys,
Just updated to the x10 after my samsung galaxy died on me, so far i am rather happy - except for the lack of root, but that will come.
I have noticed many complaints on the forum about battery life, and have experienced the same thing myself. From my experience, i think this looks like the same issue that was faced on a leak of 1.6 for the galaxy - it was referred to as the "No Sleep Bug".
TBH, the name says it all - for some reason, in many builds of android 1.6, phones were not sleeping correctly. There are many theories as to why, from cpu not being allowed to sleep, to permanent communication with google servers.
Despite all these different theories, one thing seemed to fix the problem - turning off all location services. Some people argue that a different carrier build, turning off just 'share with google' under location, turning off just AGPS etc. would fix it, but from my experience, the only real way to fix the issue was to turn off all GPS usage unless you need it. The once you have used it, reboot your phone.
This fix obviously sucks, and a new fix has recently been released by a veritable android-demigod around the Galaxy.
HERE IS A THREAD ABOUT NO SLEEP ON i7500 GALAXY;
(ok, some stupid rule says i can't post links - can a mod help me out?)
HERE IS THE FIX FOR THAT PARTICULAR BUG;
(ok, some stupid rule says i can't post links - can a mod help me out?)
LINKS ARE IN POST #5 - THANKS TO ONDOTEAM (would still be nice to get them in this original post though)
Now, from my experience, no sleep behave exactly the same way on the x10 as it does on the Galaxy;
1) I turn of all location services, and my battery life at least doubles.
2) After said turning off of services, 'spare parts' no longer says 100% running time under battery usage - in fact it can be as low as 10%.
These two factors are identical to my experience with Galaxy. SO; is there any way drakaz's fix can be applied to our X10's? It seems to me that the files he mods are standard Android system files, not sony/samsung specific.
Now i am no developer, so i dont know it this is possible - the first question that comes to mind for me is "do we need root access, or can this be done through developer tools using the android SDK?"
Can anyone help shed anymore light on this?
Seems to work for me. I disabled all location services. Spare Parts went down from 100% to 7.6%.
I'll just have to enable GPS when I need to use it..
Awesome! Glad to hear it has helped.
Let's keep testing this guys - if it does show up to be a big cause, then perhaps the devs around this place can help is figure out a patch for Drakas' mod to make it work with our x10's!

No sleep is easy to fix, took me a while to figure it...
Turn your screen brightness from manual to auto, spare parts will now start showing proper running stats, no more 100% running.
The screen is a little dark in auto but it will cure the 100% running.
GPS and location services etc make no difference to my X10i, I am running the 1.6 version unbranded UK handset, the only thing to stop mine running 100% is to put the screen on Auto.

Drakaz has done some fairly deep digging and is next to certain that it is an artefact of the geolocation bug discussed in the thread in which the problem was fixed.

Spare parts is indeed available from the market - it is a much more powerful tool for indicating battery usage than the regular android methods. The galaxy stared on 1.5 which had NO indicator of battery usage statistics at all, so we all learned about spare parts very fast.
Perhaps that is why no x10 users have realised about the potential no sleep bug; because so far only the android usage indicators have been used?...
Anyway, hopefully this can help us all understand the way our phones are working better together

14% it's mine value for running time, not 100%. By the way thats 30 minutes of 210 in total :S
I'm also experiencing "No sleep bug" after i used GPS. I use Battery Graph to plot my power consumption and after I use GPS, I can clearly see that power consumption is high even if i turn the phone in plane mode.
In addition SE widget, used to turn on/off GPS, seems to not work very well for me. So, to fix the bug, i manually disable GPS in parameter menu and restart my phone. After that power consumption is hardly null (20% in 8h with MP3 on almost all the time).

Do you have 3G always on?
My phone has no trouble sleeping.
Gps hasn't really been an issue but I keep it off when not needed.
Here's my solid settings:
1) No auto sync
2) No moxier
3) Gps off
4) Restart after using wireless
As long as it's like this my phone lasts 2 days easily

I have been playing with mine for a month to work out what caused mine to not go into sleep, I keep GPS wifi etc on 24/7 but in spare parts I was running 100%, after numerous reinstalls and removing everything i chanced on turning on auto screen brightness, now when i unplug my x10 the running sits at the correct level.
No Geolocation bug here
I have this problem with 100% on and off. Sometimes when I check its under control (~10%), other times its at 100%. I have GPS off, no WiFi, auto brightness... don't know why it sometimes just gets stuck at 100% :/

[Q] Bluetooth power drain on standby

It seems that we all post our results on standby with certain thing enabled (GPS, WiFi, Data Link, Synchronization) but we keep on dancing around the subject of bluetooth. I've noticed that a lot of us have claimed that bluetooth enabled in standby is the most prevalent cause of the 60mA+ consumption so we just relegate to turning it off.
The thing is, turning off bluetooth while in standby defeats the purpose of "hands-free" usage. Turning off bluetooth means we have to answer the phone by getting the handset out of our holsters/pockets/coats/purses, whatever then manually enabling bluetooth, then, in some cases turning our headsets on again and waiting for them to pair, just to be hands free.
Of course, that all sounds like a hassle but that seems to be the reality of the situation now. The Devs (Chefs) and community have done well in finding solutions for various issues, but I haven't really seen an initiative towards resolving the bluetooth issue, other than "turning it off during standby".
So I guess, long story short... "Has anyone found a fix (confirmed) with the bluetooth standby power drain problem"
seems like no one has any ideas . On a good note, bluetooth power consumption (while in call) peaks at the beginning, but into the conversation, you can see the power draw get less and less. Bellow 200mA.
The drain issue doesn`t happen in Sense builds I`ve been using Gauners HD NAND build for the past week with BT on and I was getting 4-7mA drain in standby. I`ve now moved to MDJ`s CM7 NAND build now that BT, GPS etc are working. However the drain is 63-66mA with BT on and an average of 7mA with it turned off. Not as yet seen a fix for it.
Radio
I have the same issue.
Have you guys tried different radios with any varying success?
The problem seems to be in the stock kernels but I thought I'd see if anyone had luck with other radios?
Same for me.
Some time ago i played arround with a SD build to change the three bluetooth libs from a sense build in my stock build. Powerdrain was low and i was able to pair a bluetooth device but unfortunately i cant connect.
Maybe a developer can have a look on the BT powerdrain problem?
Best regards
trilu
Cheer!! I've got this problem too.
-67ma if on,standby
-6ma if off
Didn't found this problem on WMP.

Have tried a few different radios to no success.
Hopefully someone figures this this out!!!
It would be nice if they made a sticky for people that have tried different "fixes". I've noticed as well that this is not a sense build issue. I have tried different radios as well to no avail. thinking about resorting to a wired headset, lol. I think this has something to do with the Kernel. I've read, in some threads about a "toolchain" issue that has been mentioned to be the primary cause of this. We may all find temporary or lucky fixes but I believe the end-all fix will come when someone figures out how to find the cause in the kernels we use for our builds.

Battery dying very quickly - what to do?

My Evo battery is draining at a rate that is all together too fast. I took it off the charger about 3.5 hours ago and it has drained about 30-40%. I have not made a call nor used the net at all save for the receipt of 3-4 emails. I had a rooted phone but I reset the phone back to complete unrooted stock. I have not even so much as installed an app. What can I do about this?
turn off your mobile data when not in use. This will save tremendous amounts of battery.
if you search the forums you should find countless threads on battery and how to find out what is draining your battery and to extend life.
not sure why you would unroot unless you were exchanging it at sprint store but it greatly limits what you can do to help prevent battery drain. If you dont want to mess with much jsut use a rooted stock rom and it is pretty much the same thing as being unrooted but you keep the extra rooted benefits.
your best bet on non rooted device make sure mobile data, 4g, auto orientation, bluetooth etc are turned off. do the HTC battery condition/charge trick. and turn off background sync.
my suggestion is to re root and look into undervolted kernels and many other battery saving tricks found using search!
hopefully it helps some.
I had the same problem OP.
Turns out my radios weren't update.
Head over to the developer section and download the newest radios and stuff.
I've seen significant improvement of my battery life by using Collin_ph Battery Tweak 1 that was offered by Myn's when I flashed his/her's rom. I had my BF take his Evo to work after he come home complaining that the charge would only last about an hour or two and behold, he got through the whole day without having to charge his battery. This is after listening to music at work for 8 hours also. I HIGHLY recommend this tweak for ROOTED PHONES as I and everyone else I've recommended loves their Evo now and have no complaints...I'm at work right now and I'm at 79% and when I usually get home the battery is either still green (full) or orange (med) charge. I'm not sure if this tweak can be used with other mods but I'm very happy with this tweak as it has made my phone perfect now~~
Could be a Rogue app running killing your battery or radios not updated like stated above.
I recently started having the same issue. Advice such as turning of data and the GPS aren't helpful since the device functioned fine with GPS and data on before. Also if the battery was draining at a slower rate on the current radio before, you shouldn't need to update it, should you?
Seems that either something is making the Evo use more juice than it was before or that the battery is not holding the same capacity it used to. For some reason Phone Idle and Cell Standby have been using quite a bit more juice than they used to.
I don't like some of the software mentioned to try and locate anything that could be using more juice since those programs seem to use quite a bit themselves. Either way, what could be doing it that would come up as Phone Idle or Cell Standby in the included battery monitor? Wouldn't anything else come up under Android System?
The battery draining that quickly is not normal even with background sync, GPS (idle), 4g, data, or anything else on. There is another issue which must be solved. To troubleshoot so far I've tried another battery (same thing happens) and now I'm trying with everything turned off. If I can isolate what was causing my sudden rapid battery drain, I'll update everyone. This just started a couple nights ago for me. I think I'm on the latest radio, but I'll check.
Last post sums up my problem perfectly. I have an extended battery that lasts half the time it has over the last 4 months. Started with the radio updates. running myk
Use the battery usage functions of 'spareparts' to determine what's consuming cpu or preventing the phone from sleeping.
Can't fix the problem until you've isolated what's at fault.
Turning off mobile data will indeed fix a problem of some app trying to access the network, but it won't solve the actual cause.

I think juice defender does this automatically when the screen is off.
In the case of my phone, and I believe the OP's, we don't have any rogue apps or things running in the background. I know this phone like the back of my hand. I have completely uninstalled unnecessary apps like facebook, twitter, all things like news and weather are on manual update, i don't keep 4g or gps on, and I use wifi at home. I turn off 3g in terrible reception areas. I'm not a new user who doesn't understand the basic ways to save a little battery. I'm pretty sure the OP isn't either by his post. I use my phone the same every day. My chinese extended battery would last me easily from morning to bedtime with 20 to 30 percent to spare. Now I can't get near that after the radio updates. Since it's been well known that something is weird with these current updates, I've downgraded to 1.77 to see if that helps. My phone was sleeping fine though, so I don't know how much it will help. Always some BS with this phone.

I appreciate it. I really do. But that is exactly the things I'm saying are already off. GTalk is turned off immediately on my phone from the jump and latitude has never been opened. It's got to be radios. I guess I'm not really asking a question, I'm just telling the OP he isn't alone.

this is the thread with flashable .zips of alllll the radio updates ever out for the EVO.
http://forum.xda-developers.com/showthread.php?t=715485&highlight=radio
if you are having trouble after a radio update, just try some of these other radios and see if that helps
Your best bet would be to root your phone again and give one of the SBC kernels a shot. I'm running CM 6.1.2 along with Zendroid 1.1.0 BFS AVS SBC and I can easily get 16+ hours with HEAVY use. And when I say heavy use, I mean hundreds of sms, dozens of calls and lots of websurfing. You will love the SBC kernels. Give it a try.
PS. My name is HondaCop and I approve this message.
We can offer suggestions until we're blue in the face.
First off, the OP needs to provide specifics of what's installed on the device, including rom, kernel, radio, etc, not to mention the hardware version itself.
Assuming it's not the known pri /rom conflict, then determination needs to be made as to what's actually consuming cpu - see first sentence above.
Need to use a systematic approach to troubleshoot this, otherwise it's a waste of time.

That sounds like a very weak cellular signal is forcing the radio to keep searching for it, draining the battery very quickly.
One way to somewhat alleviate this problem is to force roaming, to connect to a provider with a better signal.
"Roam Control" app does this (Market).

Answer to bad battery life: phone never enters sleep state

Hi,
i noticed months ago the following on my IDEOS X5 (german) concerning bad battery life. It could be the reason why there are so many different reports regarding bettery lifetime of the U8800.
First - why did I start to investigate: because the phone sucked about 5-10% per hour while not beeing used / lying on my desk, so after max 20 hours the battery was empty. But this did/does not always happen....
What I did: it took some time to get used to android (its my first droid) and learn how to troubleshoot. A month after I got this phone I learned that the GSM-code *#*#4636#*#* will show you very useful information concenring battery/phone usage. I started to play around with the phone (factory reset, install/remove apps, enable/disable different options like 2G/3G/WLAN etc...) always keeping an eye on the 4636-infos.
Result: When I use WLAN the phone simetimes enters an "state" when it never again enters "sleep state" and the battery gets sucked as stated above. I switched off WLAN for a week and this did not occur while standby time increased to 48 hours and 4636 stated an "phone awake" percentage of below 20% (normal usage). Once I reenabled WLAN again it took about an day of WLAN usage to reproduce the bug and "phone awake" time increased to 100% while standby time decreased to below 20 hours. ONLY rebooting the device recovers from this "state". I further noticed that this does not happen if just WLAN is available but no 2G/3G (phone had no SIM). My conclusion is, that the
"You May Be Charged"-Popup is the culprit. It does lock the phone to this "state" for some reason, mybe when the WLAN connection is dropped while the phone is not used (traveling). Can someone reproduce this on his phone (maybe not german)?
Resolution: IMHO none. I send the device twice to reseller for service. First time the complete mainboard was changed without success regarding the battery drain. Second time nothing was done - they just returned the device to me.
Thanks.

This is affecting ALL Froyo Roms, if you want battery life, install Oxygen or CM7...which are based on Gingerbread.
There is no point in discussing this issue anymore, this is a very well known problem and Huawei doesn't care.
Sending the phone back to manufacturer won't help at all.
Thank you for the hint - it realy looks like the same issue. Knowing more about the nature of this issue could give people not willing to install custom roms a possible solution. Can someone move this thread over to that one?

I hope some more bugs are straightened out like headphones and internal mic at the same time. Headset button to work. Battery time!
none of my android phones could use the phone's mic when headphones were plugged in
I saw a solution for the mic-with-headphones-problem a few days ago, either here or at modaco (do not know if it is confirmed working though).
fajabird, I know that you want this to work with the ROMs provided by Huawei. Huawei obviously does not care too much about providing the community with updates (they do not even have gingerbread-support by now). This is the downside of this low priced phone.
Let me just say this: It took me about one hour to understand the ultimate-guide at modaco. It took me another hour to decide which ROM I want to use. If anything goes wrong at the installation I can easily start over again. Now I have a fully working phone with Android 2.3.5 with a battery that lasts at least 2 days, sometimes 3(if I do not play any games within that time). Of course I understand that you are probably very pissed at Huawei for providing a ROM with a bug that serious.

Hi, thank you for sharing your experience with me. I always wanted to update to some custom roms but the time I started investigating this issue there was no stable one out there. On the other hand I thought there might be a dev interessted in more details regarding this issue helping him to sort out this nasty bug for whatever reason.
Can someone tell me, if his U8800 also has the ambient light sensor but like mine does: it won't reduce the brightness, just increase works. Thanks.

Mine reduces brightness but does it quite weird sometimes like adjusting several times without the light around me changing...
Mine always adjusts it way too low. If I am inside the brightness is always on minimum. I use the power-widget on the homescreen. I only change it at night, it is on max. for the whole day (the max. brightness is still kinda low, especially if it's sunny).

Hi,
i noticed months ago the following on my IDEOS X5 (german) concerning bad battery life. It could be the reason why there are so many different reports regarding bettery lifetime of the U8800.
First - why did I start to investigate: because the phone sucked about 5-10% per hour while not beeing used / lying on my desk, so after max 20 hours the battery was empty. But this did/does not always happen....
What I did: it took some time to get used to android (its my first droid) and learn how to troubleshoot. A month after I got this phone I learned that the GSM-code *#*#4636#*#* will show you very useful information concenring battery/phone usage. I started to play around with the phone (factory reset, install/remove apps, enable/disable different options like 2G/3G/WLAN etc...) always keeping an eye on the 4636-infos.
Result: When I use WLAN the phone simetimes enters an "state" when it never again enters "sleep state" and the battery gets sucked as stated above. I switched off WLAN for a week and this did not occur while standby time increased to 48 hours and 4636 stated an "phone awake" percentage of below 20% (normal usage). Once I reenabled WLAN again it took about an day of WLAN usage to reproduce the bug and "phone awake" time increased to 100% while standby time decreased to below 20 hours. ONLY rebooting the device recovers from this "state". I further noticed that this does not happen if just WLAN is available but no 2G/3G (phone had no SIM). My conclusion is, that the
"You May Be Charged"-Popup is the culprit. It does lock the phone to this "state" for some reason, mybe when the WLAN connection is dropped while the phone is not used (traveling). Can someone reproduce this on his phone (maybe not german)?
Resolution: IMHO none. I send the device twice to reseller for service. First time the complete mainboard was changed without success regarding the battery drain. Second time nothing was done - they just returned the device to me.
Thanks.

Hey there friend, I've detailed much of this and been through a lot of troubleshooting. It did not appear to be the "You may be charged" popup as I disabled that whenever I changed ROMs. I never did get a solution for any of the Huawei ROMs, it just seemed like bad code as Dzo pointed out with the WiFi driver.
A very simple solution for me was installing one of the 2.3 ROMs, they are quite stable at the moment, especially Oxygen (although I use MIUI). You will find much better battery life with these.
Best of luck,
Ryan
My stock rom 2.2.1 Shows Android System 97% battery usage and battery drains 50% in 19minutes! With wi-fi, 3g, Bluetooth, everything is off and even i do not use it.
Flash latest official 2.2.2, wait for official 2.3, flash the custom 2.2.2 rom void or flash a custom 2.3 rom. I would recommend flashing the latest 138 or 162 to get the latest modem baseband or manually install the AMSS.bin.

I can't because phone do not use my external SD card somehow. In android i see files but in recovery-it does not use external sd.. I ask in forum why-but nobody answers
Backup ur data on it and format it. If that doesnt work ill send you a guide how i fixed mine, its just a partition error.

I formated it via phone, then via PC - it works in powered on phone in android, but in recovery it doesn't it only sees sdcard as internal memory, if i try mount sd-ext shows error, can't mount.
Also i have problem if i use pc to copy some files to internal memory-phone switches storage mode OFF! and i can't copy files to internal 2GB memory..strange

Bluetooth causing wakelock?

Just noticed yesterday that my battery life has been pretty poor on my new Nexus 6P. It took me a while to narrow it down, but I finally noticed that Bluetooth appears to be keeping the phone awake.
Whenever Bluetooth is on, regardless of whether it's connected or paired to anything (I normally use Android Wear, but I completely unpaired all bluetooth devices on the phone), "Android OS" in the battery info screen appears to be stuck awake. Its "Keep awake" time grows continuously as long as Bluetooth is turned on.
Has anyone else ran into this issue, and have any idea how to fix it? I really can't be leaving Bluetooth turned off, and the phone is not really going to make it through the day like this.
Yes it's been happening to me. I didn't know what was causing it until I saw your post. It seems to be a glitch with Marshmallow and not the phone itself. My Nexus 9 was also stuck awake until I turned off Bluetooth.

Hmm. Maybe that's why my battery drained so fast. I'll have to turn off Bluetooth and see if it makes any difference

Have you disabled the bluetooth scanning under locations --> settings (the 3 dots) --> scanning.
You can also disable the wifi scanning in there too.
No, I have disabled Bluetooth scanning and it is still occurring. As long as Bluetooth is turned on, the device stays awake. There's something more serious at issue here.
That's disappointing if true. I use BT all the time and leave it on 24/7.
Aw man, bummer hearing that as I keep my Bluetooth on all the time, and am waiting on my 6P. I actually had this same issue on my Note 4 a week ago, but I was able to narrow it down to a 3rd party app called "Gas Buddy" by using Greenify and CPU Spy. And this only happened whenever Bluetooth was enabled.
I know you said Android OS looks to be the culprit, but if you happen to have this app, try uninstalling it (or blocking Bluetooth permissions for the app). Otherwise, there might be another app pinging Bluetooth to keep the phone awake.

I was seeing the same issue, if BT was on, there was a 100% bluesleep wakelock. Lots of searching later, turns out the Gasbuddy app was the culprit. I still don't understand why, but that was the problem for me.

I turned off BT and got significantly bettery battery life. I only use it when driving in my car so it's not a huge deal for me to have to turn it on/off, but there should be a fix for this.
Man, I'm glad I found this thread. It seems to be the only discussion about this issue on the entire internet! After two nights of 20%+ battery drain, and waking up to a completely dead phone one morning, I'll try turning off Bluetooth instead of returning the phone. Here's hoping for a fix soon. This is a pretty unacceptable problem.
Damn, sucks for those of us with smartwatches

Do you have gasbuddy app installed?

I don't.
i had just posted my (poor) battery life on the battery life thread, and then read this. I did have the gasbuddy app installed, and was keeping BT on 100% of the time. I have since removed the gasbuddy app, and disabled BT for now to see if makes a difference. Maybe its the placebo effect, but my drive from home to work seemed to have killed very little battery since i did this. Ill know better as the day progresses. While it would be annoying to know this is what is causing the wakelock, id just be happy knowing how to manage it until a fix is determined.
love you xda....thanks guy..i had the same issue and drained battery 20% overnight during 7 hours sleep. Crazy drain..... I had bluetooth and gasbuddy app.
So I disabled both and will keep you guys posted.
Thanks guys!
By the way / FWIW I've reported the correlation between GasBuddy and Bluetooth to the GasBuddy devs, and actually got a reply from them. They say they'll have it fixed in the app's next update.
Hello supertoast,
I have forwarded this feedback along to our development team for review to be fixed. They're aware of the problem and it should corrected in the near future. Thank you for bringing this to our attention.
Regards,
John

Nice to know. I also sent something to them as well.
Hopefully they fix it, it saves me money when finding cheapest gas...
Is there a way without root to determine what app may be wakelocking BT? I don't have GB installed and I get pretty bad battery life with BT on.

Well besides Gas Buddy, it seems that from the above posts that its a fundamental bluetooth issue in marshmallow. So it doesn't matter which app uses it.
It could be, but the GasBuddy correlation for my Note 4 was on 5.0.1. It may very well be some 3rd party app going rogue. That's from my experience though - it could be Marshmallow in general causing it, for all I know! Still waiting on my 6P to experience it. [emoji14]
