2.1 Blue Tooth Drain Issue ?? [6.35 Radio]

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.

Bad battery life is typically not because of the hardware

Hi,
I'm posting this in return for all the information I found about the HD2 and poor battery performance. I read every thread I could find and every single post in them. I learned a lot and that allowed me to solve my problem.
I got no more than about 10 hours of use out of my battery with average use. Initially I thought this was the norm, reading a number of threads on this issue. I could however not believe that the performance was so poor, even taking the large screen into account.
I decided to try and determine exactly what it was that caused the battery to drain to quickly. I loaded BattLog and found it invaluable (see http://forum.xda-developers.com/showthread.php?t=444920).
I immediately noticed that my phone was drawing 85 mA even when it was in standby (or what I thought was standby). Based on what I was reading, the current draw should not be more than 5 mA while the phone is in standby.
I noticed in one of the threads that there were complaints about G-Profile causing battery drain. Since I had it on my phone I thought that might be a logical place to look. I uninstalled it a lo and behold... the current draw fell to below 5 mA when the phone was in standby!
In addition I loaded Bandswitch which switches off my 3G connection after it has not been used for 60 seconds.
Now I have about 48+ hours of battery life. When not using the phone a lot it extends to a lot more than 48 hours.
The long and short of it is that if you get poor battery performance, chances are it is because of some software that is installed on your phone.
Here are a couple of usefull things I have found in helping resolve my battery issues:
1) Use Batlog (http://forum.xda-developers.com/showthread.php?t=444920) to log the current your phone draws. If it draws more than 5 mA during standby you have a problem, most probably related to a piece of software on your phone
2) Your phone should not be drawing much more than about 150 mA when in 'active' mode with the screen at 40% brightness.
3) If you are running G-Profile, uninstall it and recheck your current draw. Chances are that it is the culprit.
4) Having an active data connection does draw power from the battery. In my case this is about an additional 130 mA. Load something like Bandswitch to disable the data connection when it is not needed.
I hope this information helps somebody. I realise that the situation is different for everybody out there because of all the variants such as age of the battery, sofware loaded and use. However, the reality is that the battery issues are most probably not because of a bad battery or the hardware but rather because of software on the phone.
BTW I am running:
OS Version: 5.2.21869
Manilla version: 2.5.19211619.0
ROM version: 1.48.421.2 (71294) WWE
Radio version: 2.05.51.05_2

batlog?
Hi Gerhardvr,
What is the batlog software you used?
I'm very interested about your post.
Thanks.

Very useful findings, gerhardvr. Thanks!

found BattLog

Have a nice day guys.

When I ran the Test, it said that I was using up 242mA in standby! I dont believe I have G-Profile installed, unless it was pre installed on the device. I have the latest versions of the ROM, Radio, Manila, and OS version, so I know the culprit cant be the ROM version... Any ideas? I bought this phone from T-Mobile US.... Sooo yeah

Folks, I've been trying to get to the bottom of this as well. I have a number of cab files which do seem to help a little. One of the bigest culprits I've found is the screen lockers. Disable them and see how you fair!

Soopahsteve,
I suggest you use Battlog to log to file. This is very useful as it will log the time stamp, the current temp of the battery and the current draw at the point in time. In addition it logs arious events on the phone, in particular the startup and shut down of applications, data connectivity, when you make or receive a call, whether you are talking or receiving on the call, etc. This can be opened in Excel and then analysed and if you are very lucky, you will pick up some patterns allowing you to link some programs to the battery drain.
However, the situation is typically slightly more complex to resolve since the culprit software are usually software that is loaded as TSR application at reboot. The result of this is that Battlog will not show the startup of these applications in the log file since they are already running at the time you are starting Battlog.
You should look at programs that manage phone profiles, screen lockers, screen calls or SMS messages, etc. In other words, any program that does work behind the scenes.
The reason you are seeing 242 mA in "standby" is because your phone is not really in standby. Although the screen is blank, something is preventing your phone from going into true standby, the processor is still active. The trick is to find what this is.
Sometimes the only approach is to uninstall the applications you suspect one by one and see if it makes a difference until you either find the culprit or can prove that none of the them are an issue. Then reinstall the ones you think are "safe" one by one and check whether the probelm pops up again. unfortunately you have to do the double sided approach because there could be more than one application that cuases your issue.
Painful I know but worh it when you have two days worth of battery time with some to spare.

You know it. In reality I would love to upgrade to the latest and greatest but I've customised my phone to the Nth degree (did obviously not upgrade the ROM) by installing all the little apps I find useful, Cookies Home tab (best thing since sliced bread), etc. My phone is now just the way I like it.
It would take me quite some time to upgrade the ROM and to customise it again from scratch and I really don't see the benefit. I might be force to do it when I get to a stage where there are software that I would like to load that only works on the later ROMs but until such time I'm not gonna try to fix that that ain't broke.

is this the bandswitch u are using? if not, can i check where to get the program?

I just upgraded my ROM and did a Level 1 restore with Sprite Backup ... everything comes back except (I think) for wifi passwords.

i am drawing 180mA on standby..
im using custom rom, energy rom so thats very strange, but i have to agree that my battery life is terrible.. so i got to find a way to cut down on the 180mA drain..

I've always had good battery life on stock 1.66 rom losing 3% overnight with wifi and bluetooth turned off. Had to do a hard reset and started losing 15% overnight with the same everything. Did further resets and got nowhere. Ended up giving up on 1.66 although it had been fine previously after numerous hard resets - makes no sense but this is what happened. Just flashed to 1.72 and back to losing 3% overnight what it should be. And that is out of the box, to be honest all the battery saving registry tweaks are not worth the time installing and I leave 3G on all the time with updates coming through.
So it's all a bit random and shame on HTC for not sorting it out. My advice is do a hard reset, switch the wifi and bluetooth off and see in the morning if you have a reasonable battery life (or use the batt consumption program to verify standby consumption is sensible). Do this first before installing everything, getting frustrated and starting over again like I did when you discover that you're still experiencing high battery drain. This ensures that your starting point is a good flash and the phone is getting good life before adding any apps that could be causing a problem.

i have found my hd2 really does not like being in a poor or no coverage area. other phones i've owned have normally coped pretty well with no or very little signal. but not the hd2.
also noticed more drain in areas where there is only poor 3g coverage and its switching between 'g' and 'h' coverage.

Energy ROMs, just like the name goes, use a lot of Energy
They are baked in with a lot of performance tweaks so it's not unusual to get lower battery life per charge compared to other more down to earth vanilla ROMs.

Thanks for this thread, a lot of interesting information about the battery life of my HD2.
Just to mention: battconfig shows the power consumption directly in the task bar, a good way to find power guzzlers while they are active.
It's a pity we have no central place in this forum with a list of background applications that are known to drain the battery faster.
Or, also a needed information, a list of applications that are known not to do this (like PhoneAlarm, PocketShield).

I'm using the official rom only and have non fancy apps running or installed while I'm using the test bat program. As I speak the SD card is removed and celular radio is turned off.
Acording to program there is an indicator which is switching from -229ma to +78ma is that what its drawing of power?

+78ma??? That must mean you are charging the battery. The best way to test current draw is when it is only on the battery.
I get about -5ma draw on standby and it tops out at around 180ma when I have the screen on, but usually hovers around 130 - 150ma. I have my screen brightness at the lowest setting possible.
@OP, I wanted to say this earlier... great topic, very insightful.
I have a few suggestions for everyone posting in this thread. Let's try and get some common data together that is more tangible in order to give us a more similar & common perspective for these discussions.
I suggest the following
1) Soft Reset. Once the device is on, do not run ANY applications. In fact don't do anything except for following the below instructions.
2) Turn your screen brightness all the way DOWN! (Turn off Auto Backlight and manually set it to the lowest setting)
3) Check your power settings and make sure that while your phone is on battery, that it is set to dim the backlight after 30 seconds and turn off after 1 minute
*** I have attached 2 REG files below for both Backlight and Power. Please use them instad of doing it manually.***
4) Turn off all the radios (Phone, Wi-Fi, Bluetooth). Let's make our first round of tests with the Radio's off. Radio ON complicates things a bit as there are several applications to keep track of that use the Data Connection. I'll come up with a more comphrehensive list later so we can do the Radio ON tests.
Screenshots
Use a program like Shave&Save and get the following screenshots
1) Use any Task manager and get a screenshot of all the processes running. Sometimes the number of processes displayed is longer than the screen size can accomodate. Take 2 screenshots in this case making sure that you capture all processes. Edit the image with MS Paint or some other Image Program and attach it here as one image. See the example in the post below this one.
2) Goto \Windows\Startup and get a screenshot of the folder contents
3) If you are using Sense, drag the slider all the way to the end (settings) and goto About Phone. Goto Software Information and get a screenshot of that.
Monitoring the Battery
1) Make sure your phone is not connected to the charger or to the computer.
2) Open BattLog (can be found here), set the refresh rate to 1 second and Start Logging.
3) After you start the logging process do not touch the screen / the phone again for exactly 2 minutes.
TIME THIS with a stop watch. As soon as the 2 minutes it complete, turn the phone back on and stop the logging.
Information to post here
1) All the screenshots from above.
2) The current draw (both on standby and while active). Also, please attach the file that logged all the information in this format: Forum ID - BattLog - dd-mmm-yy.txt
3) ROM - Whose ROM? Release Date? Does it have Cookie's Home Tab Installed or any other MAJOR Sense Modifications.

SAMPLE POST
HTC HD2 (T8585)
OS: WM 6.5
ROM: Energy * Build 21907 * Release 01.JULY.10 * CHT v1.8.5 - Dinik Edition
RADIO: 2.07.50.27_2
Current Draw (mA)
Idle: -3 to -7
Screen On (w/o Radios): -83 to -117

Those figures look normal to me. You should be getting about as good a battery life as a device like this can achieve.

[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.

58mAh battery drain on Gingerbread

Hi Guys,
I have been using gingerbread build's for some time. I notice battery drain sometimes battery drain suddenly spikes to 58mAh for sometime (without Wifi or BT)..for around 10-15mins and then comes back to normal after 10-20mins(<10mAh). I experienced this issue first in MDJ Cm7 2.6 build..I thought that time must be build specific..so I switched to Desire HD build which was free of this issue...however I don't like sense anymore, so moved back to typhoon's CM7 build.But again I encountered the same issue. I changed the kernel to gauner's kernel, since the desire HD build I was using was using this kernel and free of the issue, but again it surfaced back.
Now I switched to pongster's hyperdroid build. This build has a very low power drain...most of the time its < 4mah on this build...Also I haven't installed any widgets (except for current widget) and have still the stock ADW launcher (to rule out the possibility of this bug caused by any s/w)...but again the drain jumped to 58mAh .Is it just me or other gingerbread users face this drain also randomly. could it be due to SD card, I am using ext4 data partition.

hmmm, I don't know, maybe its an install issue, I have everything always syncing, but I also have only 2g connection (at&t's terrible network) and I haven't had this issue using both pongsters and mdj's builds

Hmmm ok...I don't think its an install issue..i always do a task 29 before switching builds from different devs..and follow the CWM settings as recommended by the dev....rest the builds are running so smoothly especially pongsters without any FC's or such...
BTW why are using AT&T...t-mob is cheaper and faster(3g)

It happens to me too sometimes. What I do is disable wifi and gps wait two minutes and battery drain on standby becames 5mA again. When I enable both again, it stays on 5mA. Don't know what's causing it, but I have it too.

I have this Problem if I use Livewallpapers.
Now i use normal Wallpapers and it is gone.
edit: 5-8 mA with normal Wallpaper

Well for me, it turned out to be the sync indeed as XsceneXhippieX mentioned.
I turned off all sync just for the heck of it and the problem hasn't come back for last 2 days...I enabled Background Sync (not auto sync) and problem resurfaced within few hours...so i'm pretty sure..Its the sync which is causing this Guess I need to go back to Sense ROM now...
And BTW i'm not using live wallpapers..
Also one more interesting fact...phone conusmes more battery on 2G networks than on 3G. I forced to phone to use 2G network and idle power drain was >5mAh all the time...while on 3g its 2-5mAh mostly...

58 mah on Ginger is usually the GPS. Turn it on then off again, somehow if you use it or any app use it, even if the app closes the GPS chip doesnt turn off.
Just turn it off using the widget or in settings.
If that doesnt fix it, make sure Bluetooth is off. it consumes 58-59 mah, even if it is not connected, its a known issue on Ginger. Bluetooth never goes to sleep, gotta turn it off manually.
Hope it helps!.

Thanks for the help, but I'm sure its due to sync...I turned off the sync and for last 3 days there hasn't been a single occurrence of 60mAh drain.

gonna try turning off sync cause ive been having this issue.
just tried second gingerbread rom and it began immediately,
and this is with data, wifi, bt, gps all off.
hopefully sync does it

turning background data off didnt help.. still getting 70 to 80 drain.
and playing music in standby had me up to 110 which is higher than usual too

Is it a spike or continous drain? Also which ROM/kernel are you using?

its a spike, other weird thing is since i got on gingerbread, currentwidget has sucked at getting a continuous read. it has big gaps in the log.

Yes currentwidget don't give a continuous read for me too...but its the same behavior in froyo based sense build also...
Anyway, are you using any widgets installed which sync? Disable them and see, though i'll advice to disable all widgets (not only ones which sync) and see

score mobile and stock weather i have. but if i turned off background data and autosync they shouldnt be able to do anything i thought?
il give it a try
and currentwidget always did minute by minute for me in froyo. on sense at least i cant remember the last time i used a stock build

Well I had fancy widget installed in which I had set weather to be updated always (irrespective of background data option) once a day and only on Wi-Fi..yet it still caused 58mAh drain....try disabling them for a while and see...

just deleted score mobile and deactivated weather.
after a few minutes turned it on. 85ma...

You can change the kernel to see if it helps...try Gauner's or RAFPIGNA
or better switch to froyo build...i'm switching myself..there's not much use to smartphone if you turn off syncs anyway

yeah i guess back to froyo. whats the best stock one? def dont want sense anymore.
and has anyone made an app or something to do the awesome shutoff animation from 2.3?

[RESEARCH] Mobile network standby drain (Oreo)

Since the first release of oreo I started using the rom as a daily driver, later on paired with a good kernel it had some good perfomance
But after some days of using the rom i started to notice a huge battery drain caused by the Mobile network standby process?
My battery was old (OEM 2014 battery) so i decided to revert back to lineageOS just after a couple of days where I haven't had any issues with that mobile network standby
Now I'm really curious what is causing this issue,drain because I am using the phone on the same settings as on 7.1 nougat, I am living in a country where all networks run on 3G,H+,2G etc. so no 4G if this can be a cause
Changed the network modes many times and tested throughout the days but there was no sucess the drain was still persist, tried updating,downgrading bootloaders swithing modems but again no sucess
If there, in the world of android is any solution, here is the thread to discuss about this issue. :fingers-crossed:

I've wondered this too. I've been running los15 on my g900v , I rooted and boot the first ROM that would work without having or remembering todomuch, I ran the first custom kernal I could find via google, and ran whatever was noted as the latest Verizon modems. its like right off the bat, smooth , consistent battery life and nice. Then the next day I noticed things would crash, my Bt temperamental at best and restarted it just to get by. if I have sync on at home, WiFi off, it just chills , if I turn sync off and drive around town, my battery life gets eaten by the unknown. I pulled some logs to see whats up with my BT but haven't got around to it yet. But my battery too is old (I literally found my s5 in the trash) and I run weird processes and tweak settings all the time just to mess with it, so that could be it to. If I see anything weird I'll let you know.

I'm struggling with this issue for months, since the first port of an Oreo custom ROM (LOS and RR) for the Galaxy A3 Duos (my device) started being developed.
From the beginning I had this problem, and what, since then, puzzles me the most is the fact that only some of us, flashing the same ROM in the same device, experience the issue. Whenever I flash any of those ROMs, even before installing any user apps (or when running in safe mode), the drain is there, which leads me to think that the culprit must be some setting: not an app, because I have none installed; not the ROM itself, because not everybody has this problem.
Unfortunately there seems to be no developers looking into this bug.
For the sake of information, I've observed two things that should help to narrow down the issue; or maybe not.
First, all the devices affected, as far as I've searched, are double SIM.
Second, the Mobile Network Standby (MNS from now on) drain is narrowy connected with the Bluetooth drain (which "also" occurs in Oreo). I've experienced the following: If, after a full charge, I don't switch on Bluetooth at all, then what drains my battery (according to Advanced Battery Usage information) is MNS. However, if I switch bluetooth on -even if only for one minute- then what apparentlyh drains my battery is Bluetooth, at the same speed as MNS did before switching bluetooth on.
Funny enough, the battery use info reports zero minutes activity for both Bluetooth and MNS. But how can a process which runs zero minutes drain 50% of the battery?? I'm afraid that the battery use information isn't reliable. But then that's very bad news, since, in such case, it might well happen that the real juice sucker is neither MNS nor Bluetooth!! We might be dealing with a "ghost" here, since we can't even trust the battery use information provided by the OS.
If someone has something with which to contribute to this research, or any ideas, please comment.

I'm having the same trouble on android 9 betas, even better, my phone gets without signal during those times and there's nothing I could do but rebooting the phone.
How can we help solve this? it looks like it's annoying a lot of people now
