Appears that the Bluetooth PBAP process is running away when paired with my car's head unit. It was running for the duration of my drive (51 minutes) and drained about 40% of my battery. I've verified this on several drives now. Killing the process (after pairing) corrects the problem, and there doesn't seem to be any side effects.
Anyone else experiencing this (tried multiple ROMs all with same behavior, leading me to believe it is a Samsung Bluetooth stack issue)
I'm a big Bluetooth fanboy! I use the BlueAnt G2 like all the time. I have noticed on all the roms I flashed, I get HORRIBLE battery life, even though everybody boasting how good their battery life is.. I just couldn't understand it, so I aways go back to my backed up stock. I seem to get tremendous battery life on my stock rom (that came with my sgs2 from T-Mobile).. This would explain it!
I even experience this issue on downloadable tweaked stock roms you can find here. Nothing compares to my battery life when I restore my backed up rooted stock rom.
Interesting find!

That's interesting to hear. I've been attempting to troubleshoot the issue further, and I think that Samsungs bluetooth implementation is a bit wonky. I noticed their MAP (Message Access Profile [sms over bt]) is not working right, and that the PBAB responses are off a bit causing the host to attempt OBEX x-fers over and over again. Interesting that your experience with stock roms proves otherwise. Perhaps it's a kernel thing, but I think the BT stack is binary straight from Samsung.
(Take all this with a grain of salt, I'm by far an expert, and am probably talking out my @ss )
I'm going to give stock a try. 51 minute drive, 100% started, 62% ended - awful indeed
SIDE NOTE: I recognize you and your (wifes) picture... what other nicks do you go by? I've seen you somewhere before.

I can confirm that the Samsung BT stack from a stock phone has BT PBAB problems. I've not looked at the battery drain because there's a much more obvious one whenever trying to pair the phone to a BMW bluetooth system. Once connected the car system cannot download the phone's phonebook without first killing the PBAB process first. If you Google for BMW and PBAB you'll be able to read about lots of folks having this problem including this thread, and the only solution is to kill the PBAB process.
Funny enough there isn't a similar issue when connecting to a Toyota bluetooth system. The Toyota BT does support the stereo profile allowing the phone to play music over BT, while the BMW system does not.
Good Luck..
Hey, thanks for the feedback, and other forum link. I'm going to do some extensive testing with mine and try freezing selected BT services to see just what happens. I've done the kill PBAB service and that seems to stop the VERY rapid battery drain.
I can usually tell it's gone awry when the phone starts heating up. (It's in a holster on my belt, and I can feel the heat start, reminding me to go kill the pbab service)
I hadn't though of freezing it (or renaming it) as I figured it was required for the phone book to x-fer. We'll see how it works out.
Can anyone confirm that MAP (Message Access Profile) works anywhere with this phone? (SMS over bluetooth)
More to come.

I've had similar experience in my Acura, albeit I reckon my situation is worse.
If pbap is running, the phone will NOT connect to the car's bluetooth. Moreover if I try to kill pbap after getting in the car, the phone (and the car) go wonky and both bluetooth systems hang until reset. The only way it works if I kill pbap before getting in the car, which sucks as it tends to start itself every time bluetooth is started.
I'm searching for a way to kill it PERMANENTLY. Any suggestions?
You can freeze the PBAB in Titanium (pro) or rename it (if you have root) - also causing a lot of problems with BMW/Nissan/Toyota and others is the BluetoothSharing process.

Samsung S II Batery Drain Related to Bluetooth
After weeks of troubleshooting this issue, I discovered that my high battery drain was caused by uninstalling the Toyota Entune application on my Android. After reinstalling Entune from the Google Play Market my phone my high CPU utilization and corresponding battery drain completely stopped and my phone works as expected. Perhaps corruption from the install/uninstall of phone to car software is causing Bluetooth corruption:good:.

PEACE,
YES!! It appears that my browser cant even get some pages (or it takes forever to load ---for instance XDA). I use Gtalk (I know most of you consider it BLOATWARE) and i barely can connect or 3G or 4G. My best connection is Wi-Fi which is good--when I'm home...not so good when I'm at work. I've ran the wimax test on my phone through Terminal Emulator and it stated that my wimax keys are still in tact and i have installed the latest radio...*shrugging shoulders*

I am running rooted stock (myn's I believe) with no issues... my other evo is stock 3.29 and had battery issues for the second and third days running but has since smoothed out....
Edit... using Sprint Lovers stock-ish 3.29 from over at ppcg
I have rooted odexed Rom and I can't rip out the Sprint bloatware. It's driving me insane. DC 3.6 can't come fast enough

I'm definitely having issues with gtalk..I can always connect via wifi but for some reason 3g has issues. I can connect with other 3rd party apps though, like beejive and trillian.
I am also having some issues. Used to get around 20hrs or so under moderate use. Now it seems to be more like 12 possibly 16. I get a very weak signal at work and this new update seams to drain much quicker. been thinking about rooting. Have done a lot a reading but not 100% sure how to do it yet.
same problem here. So I read elsewhere to check your Accounts and Sync in the settings. The update reenabled sync for stocks, weather and peep....which once I turned back off, my battery is fantastic!

I can't signin to GTalk since the update. I cleared the data, but that didn't help. What exactly does GTalk do?
Yeah already turned the sync back off. Gonna try rooting with unrevoked. Seems pretty simple to do.
I have had stock everything since I purchased my phone, no rooting or anything and have never had any issues with my phone at all. Since the 3.29 update, I think my phone is actually running better. The screen transitions on all my programs seem smoother, even the 4G load animation is smoother. Battery life is the same as before, crappy but I use my phone ALOT for work. I just don't know if I am just lucky or it is becuase I am using the phone as it was intended from Sprint.

Just a question, not being a smart ass, but what made you join these forums if you haven't done anything to your phone? I'm truly intrigued by the different things I can do, and I like reading about what I can possibly do.
I've been having an issue with audio applications.
If I pause a song or podcast (whether it be in the stock Music application, Google Listen, or Audio Book Player), leave the application for a while, and return there is a very high chance the song or podcast will restart from the beginning. Likewise if I do the same in Pandora the application fill crash on me.
This is mostly annoying because 90% of what I listen to on my phone are podcasts and lectures. Not being able to easily pick up where I left off is irksome.
Has anybody else had this issue?
have you tried pulling out the battery? i had alot of problems with the phone after update and so did my parents. after i pulled battery it starting working alot smoother and battery life has been alot better.

Well normally you would report bugs to the app developer, in the case of apps. But in this case I don't know, because I haven't had any of these problems. Haven't done any podcasts but I use Pandora, last.fm, or Slacker radio for about an hour a day. I use it for a half hour on the way to work, pause it since I don't use my phone at work for anything but phone calls, then play from where I paused it 8-10 hours later for the half hour drive home.
I'd try a hard reset. Sometimes updates don't work smoothly. Just look at the Sprint forums shortly after the 2.2 update. Tons of issues that were fixed shortly there after by a hard reset. I haven't noticed any issues, and my battery seems to actually last longer, when the screen is off. I just got 12 hours with several phone calls, wifi, bluetooth, GPS, maps, navigation (for a short time), and the biggest battery drainer: games. Still had 12 percent, and it probably would have lasted at least 4 hours if I just let it sit. I leave all my email push and have facebook sync enabled.
Anyways, from my experience, nothing seems broken, its faster thanks to no fps lock, overall better performance, and the battery lasts longer, though it seems to run down a bit faster when in use compared to before, but it barely loses a charge while sleeping, so standby time makes up for it. (as long as you let it sleep, which in my experience, starting with the G1, is the real secret to best battery life. Let it sleep as long as possible. Constantly messing with it, switching the screen off, only to pick it up five minutes later is horrible for battery life. Use it, let it sleep, pick it up again in an hour. If you can that is...)
Was pretty choppy until I flashed netarchy kernel. But still getting alot of FC on Internet, when I use the back button it FC.
I had issues at first but after time and 2 or 3 reboots, all is smooth.

I noticed that bluetooth is always on top (along with mobile standby) on my Defy's battery usage stats both with stock roms and with jboogies3.
Before the Defy, I was using a HTC Magic which had the same high battery usage w/ bluetooth with <2.2 roms but with 2.2 (cyanogenmod) bluetooth battery usage falled back to about 25% of the original. I thought it was improved in android 2.2.. or could it be cyanogen fixing something?
Any thoughts on this? Others also have similarly high battery use with bluetooth?

Yes, Mobile standby and Bluetooth both account for 30% of my battery use. Perhaps it's because it's 'chatting' and scanning for other Bluetooth peers all the time, I have been amazed at how many other phones you see when you scan for pairing for example.
that's okay.. but I still wonder how bluetooth usage could get restricted on cyanogen's mod on the magic with a pure software solution (as it was the same high before as well) and what we could do to achieve similar results on the defy..
ofc one viable approach is to turn on/off BT whenever entering/exiting the car, but it still sounds a bit lame for me. An application doing nothing else but turning on bluetooth in the morning and in the afternoon at a specific time for an hour could be a bit better
So...
I'm very unhappy with my Asurion forced upgrade from the Incredible to the Incredible 2. Is anyone else having these problems and is there any solution?
Aside from the issues in the pictures, the Bluetooth never gets connected. I keep getting "HF Error 68" on my stereo. I guess that could actually be my stereo though...
I'm not sure what you're trying to show with the map. GPS works great on my I2. I use it almost daily.
While I don't use the calendar heavily, it hasn't crashed one me.
I don't use Skype.
I use bluetooth frequently for stereo audio, primarily in my car. I have no problems with pairing, auto-connecting, etc.
Have you tried rebooting your phone? Contact support?
Basically, what nimdae said: no issues.
If you haven't already, try a factory reset too.
Tried rebooting and resetting my phone. Also, alarm didn't go off this morning. When I woke up the alarm thing was showing but no alarm and the "Snooze" button was greyed out and I could only press "dismiss".
With the map. I use Runkeeper to track my exercise activities. Do you see how it's jagged all over the road? It adds about 20% on to the length of every exercise. This ruins any chance or keeping track of distance, pace, estimated calories burned, etc. My Droid 1 and Dinc had fine GPS. Maybe it locks fast and works fine for navigation but for tracking anything it's terrible. I certainly wasn't zig-zagging all over the road like in that picture.
Sounds to me you have a defective phone. I can't comment regarding RunKeeper, as every phone I've had that I've tried using the app with, including the iPhone, I thought has sucked for GPS tracking.. Beyond that though, none of the issues you are seeing.
I have had none of those issues.
I have not tried run keeper but I use endomondo for running. For the most part it is VERY accurate...the only time it is a bit off is when I go around a sharp u - sometimes it cuts across rather than following the u. But I think that is a software polling issue.
I agree with the others that your phone sounds defective.
I'll have to load up one of those apps and see what result I get. It's always good to compare. I've noticed a geocaching app I used had a slight accuracy issue, but it wasn't all over the place. I was at least able to use it as a reference.
Another thing - do you turn gps on and off or just leave it on?
When I first got this phone I would turn it off and on. I noticed that when I turned it on it took forever to lock.
I leave it on now.
I don't really remember if I left it on or not but a 20 mile ride should have had a lock somewhere in the beginning.
It seems my calendar issue was just something with that event, as it works okay with editing others and after changing my alarm notification sound the alarm works.
I am still having this issue with Skype telling me that I'm not on Verizon in the US... I have the hybrid Alltel PRL, maybe that has something to do with it? The GPS issue is just too much. I rely on Runkeeper to keep track of my running and cycling and having to take note of length and route, then completely remove and manually add the every event back in just isn't going to work for me.
The GPS works great for me on the inc2, I've used it plenty of times to get me home. I use the calendar as well and never seen a F/C/ I'd call for a refurb.

There's a difference between the navigation mapping and the GPS usage he's attempting, which I intend to test with my I2. Navigation shows your relative position on a set path so if you are slightly off, it still shows you on the set path. On the other hand, things like geocaching and bike/run tracking doesn't lock you to a path, but rather tracks what the GPS radio reports is your location, whether on a road or in the middle of a field. In his scenario, his GPS is reporting him zigzagging on a road, which increases the estimated run distance and throws off various calculations.
I have some interest in this issue because I use a mapping app called Waze and because of this potential issue I've been hesitant to use the feature that allows you to map new roads using GPS.
I've been pretty busy so I haven't had a chance to hop on my bike with a tracker. I'll try to get to it this weekend if I'm not stuck on conference calls :S
@Grouper
Somehow I missed that you are using this for estimating calorie burn. I would highly recommend a Polar heart rate monitor. Any heart rate monitor will be more accurate than making a guess based on run time and distance, and I've found the Polar monitors to be pretty great, though a little on the expensive side. I like that it works with my cardio equipment as well, and I'll use it with my weight training and martial arts training.
I was thinking about getting one of the chest strap monitors but just don't have the money to spend on one right now.
I'm very curious to know whether or not I have a defective phone or if the drivers for gps on this device are just crappy.

So, I've been able to successfully mod my Sprint LG G2 (ZVC) using the MOD located here, but ever since I installed it, I've been having some severe battery drain issues whenever Bluetooth is turned on.
I use Tasker + my BT headset as a key to lock/unlock my device, so I generally keep Bluetooth on during the day.
However, since I installed this mod, Bluetooth has been utilizing 60% or more of the battery, and the drain has been extensive (the device gets very warm), and my projected battery life is about 8.5 hours before it completely drains.
Does anybody else have any similar issues with this mod? Reboots do not correct this, and the issue was not present at all (for months) before using this mod.

This issue persists regardless of tethering usage. (I don't use BT tethering, only WiFi / USB, and that's only on rare occasions, like when I travel for work).
If this mod is, in fact, the culprit, is it a viable alternative to just keep backups of the mod and original .jar files, and swap them around as necessary? I know I risk reboot looping every time I change it around (stock rooted, no recovery), so I'm looking to minimize the file swaps.
EDIT: I will also note that this happens whether my headset is connected or not. Simply having Bluetooth turned on causes a disproportionate battery drain.
Well I ran bluetooth with my photive headphones for over 2 hours, not a bit of heat generated and no battery drain. I then ran my headset with tethering on my computer for about an hour still playing music from the stock music app, with same results.
The g2 runs bluetooth 4.0 and that is a very low power consumption vs older versions.
Im thinking the culprit is either some corrupted files on your end or tasker. Im sorry I cant help more. Im just not experiencing the same thing. Im also stock rooted with only the tether mod as modified system files.
One other silly thing worth looking at is to see if "media" app is using alot of resources or wakelocks. Ive had the symptoms you describe above because of some corrupted audio files on my device in the past.

After you posted, I decided to turn on bluetooth after I got home from work to benchmark the battery drain. No overheating or excessive drain.
Since I created this thread, there have been no changes to audio files, and no programs have been uninstalled.
The audio file note is an interesting one. I'll have to re-load my albums and verify.

I found the culprit (and why a reboot wasn't helping).
Orbot was, for some reason, registering under Bluetooth for battery usage. It was configured to start on device boot with transparent proxying. When I closed the Tor connection on my device, then closed Orbot, it would usually silently re-connect and start burning my battery.
Disabling the start on boot feature allowed me to reboot without continued drain. I eventually narrowed it down to Orbot being the culprit. I'm not sure why it's reporting incorrectly under Bluetooth.
GSAM battery monitor reports that bluetooth chews up a significant amount of my battery. I have the base S22 on Verizon in the US (snapdragon) and have the latest update installed.
I don't want to have to manually turn bluetooth on when I need it and off when I don't to try and save battery. I want to leave bluetooth on all the time and have the phone properly not drain battery from having bluetooth on when its not in use.
Does anyone have any suggestions to stop this drain?
Thanks!
I don't remember having this issue, did you try clearing all bluetooth devices?
I will try that. I just upaired all paired devices and will pair them again and see if that fixes the bluetooth battery drain. Thanks for the tip.
I have exactly the same issue! I am using Galaxy Watch with my phone, do you also? Maybe that is the issue.
Unpairing and repairing my Bluetooth devices unfortunately did not fix the issue.
I don't use a smart watch with my phone so I don't think that is the issue.
I have a Bluetooth headset, my car and ear buds paired and that's it.
Very frustrating. Does anybody else have any other suggestions?

I'm afraid that might be the problem. Unfortunately, currently, I don't have time to set up my phone from scratch. However, a lot of people mention problems after using smartswitch, maybe it's one of them.
Can someone who has not used the smartswitch, confirm that he does not have the issue?
