Haha, dunno, but it would be really incredible if BBS itself was the root of our problem :D

If your results are right, then BBS would cause 2%/h battery consumption.

But I don't believe it. Will test it anyway.
[Galaxy S II Q&A, Help & Troubleshooting] Karpfenhai:
Use an older version or the latest rc from the thread, there is an open issue right now (FC)

But, BBS is a passive tool, it doesnt consume anything... You can also disable all active tasks (watchdog)
[Galaxy S II Q&A, Help & Troubleshooting] pi-xel:
Ok, got a new lead. Read in some threads that a broken PCB (USB connector with microphone included) could cause a large battery drain, of a similar magnitude that we perceive (as I've read, this happens mostly due to water damage).

As I've had some issues with my microphone lately (people I was speaking to noticed a bad speech quality), I think it might be somewhat related. Will read a bit further about it and then see whether I will replace it (new unit is ~EUR5 on eBay).

@megosu: Do you notice some issues with your main mic / USB connector / heating up of your phone?

@Karpfenhai: Any thoughts on that? Ever heard of this before?
[Galaxy S II Q&A, Help & Troubleshooting] megosu:
I have read this too online, but I don't think it applies to me. but who knows...

I haven't noticed any heating up around the USB connector, and the microphone quality is good.

Do you need to soldier the new connector to replace it ? are you going to try ?
[Galaxy S II Q&A, Help & Troubleshooting] pi-xel:
http://www.youtube.com/watch?v=-S_X02-u4z4 ;)

Doesn't seem to require soldering, will look into it today evening (as I did not have any water damage I expect that if this is the cause of the problem, then at least in my case some connections just might have gone loose).

Will read a bit more about it, if it turns out that it's likely that this is the problem, I will order and try to replace it next weekend.
[Galaxy S II Q&A, Help & Troubleshooting] Karpfenhai:
yes I know about this, but usually this manifests as "Voltage to high" notification, at least on a stock Rom.

But I think you can simply unplug the usb board, you will loose main speaker microphone and charging but the phone should work anyway, so if the drain vanishes...

Good luck!

if you look at our issue, you can see we have the same even after a factory reset, so apps are irrelevant.
[Galaxy S II Q&A, Help & Troubleshooting] diko adrian:
Hi mates, I have similiar issue with yours..

I think the main problem is in hardware, especially the usb ports, I'll take mine to service center and see what's going on :D
[Galaxy S II Q&A, Help & Troubleshooting] sakindia123:
it's definitely a hardware problem..i tried a lil' household usb port cleaning but no sweat
[Galaxy S II Q&A, Help & Troubleshooting] Ahmad-6:

try to change the usb port
[Galaxy S II Q&A, Help & Troubleshooting] merlin21:
Same thing happens to me. But today I realise that my cpu stick at 1200 and I see that several apps have a high usage... But you're right, that can't be the reason.

Anybody else have a news about the problem?!

I guess, the problem comes after my screen blinks and then a sod. Since then there is a problem with drain and heat. But it can't be a hardware thing, some days it has no drain, then I was happy and think it's gone, one day later it's back ...

[Galaxy S II Q&A, Help & Troubleshooting] merlin21:
If someone is really angry about this error, perhaps you can try to flash the phone with a RUU and report here if the error is gone?

I still want accept that it's an hardware error.

[Galaxy S II Q&A, Help & Troubleshooting] megosu:
RUU are supposed to be for HTC, aren't they ?

We already had stock rom when the issue started, and flashing custom or stock doesn't fix the issue.

[MENTION=5166900]pi-xel[/MENTION]: anything new on your side ? did you manage to change the usb port ?
[Galaxy S II Q&A, Help & Troubleshooting] diko adrian:
Megosu, try the Galaxy Note 2 mini v5.1, I have better battery life with this
[Galaxy S II Q&A, Help & Troubleshooting] megosu:
Hi,

we haven't heard back from [MENTION=5166900]pi-xel[/MENTION], but on my side, I decided to send the phone back to the repair center, they acknowledged the fault and fixed it.

The phone is now using ~2% of battery in a night in flight mode. Much better than 25% it used to drain...

I don't know what they changed exactly, I will try to find out and let you know so it can maybe help one of you...

There was also another symptom that perhaps I didn't insist enough about:

whenever I shutdown the phone, removed the battery and powered it back on, the battery graph was showing an instant drop, around 10%.

I have to check if it still does the noise in the ear speaker, I will report my findings :)

[MENTION=5166900]pi-xel[/MENTION] ? anything new on your side ?
[Galaxy S II Q&A, Help & Troubleshooting] Ahmad-6:
great news :thumbup:

now your phone back to the life ;)
[Galaxy S II Q&A, Help & Troubleshooting] merlin21:
Hi,

for me the heat and drain was gone after formatting external sd (little bit better) then a few days later killing all apps and widgets (like "my tracks"!) (a way more better) and finally (i'm always on Dorimanx) I read about wrong way of flashing rom like rootbox after Stock rom like Alliance or Omega etc.

With Dorimanx I couldn't format the preload partition and so I installed phillz kernel then formatted that partition and reinstall dori...

Seems everything is running cold and without drain now (since 2 days now.

Hope you guys find your solutions. Don't know why, but for me it works :p

[Galaxy S II Q&A, Help & Troubleshooting] diko adrian:
what do you tell to the repair center ?
[Galaxy S II Q&A, Help & Troubleshooting] megosu:
The truth,

Losing battery in flight mode even after factory reset.
[Galaxy S II Q&A, Help & Troubleshooting] megosu:
I did the ear speaker test, and it is still doing the noise, so it might not be relevant to the battery drain issue after all...

last night: 1% battery lost
[Galaxy S II Q&A, Help & Troubleshooting] diko adrian:
Or maybe they replaced the usb port?

Did you revert your rom to stock?

Unrooted condition?
[Galaxy S II Q&A, Help & Troubleshooting] megosu:
I had stock unrooted, which is why I knew it was not something linked to the rom but more a hardware issue.
[Galaxy S II Q&A, Help & Troubleshooting] diko adrian:
But actually I want to bring it to samsung service center with rooted conditions.. Is that okay? Because my warranty is over..

How much did you cost for it?
[Galaxy S II Q&A, Help & Troubleshooting] megosu:
mine is under warranty.

If yours is not, I don't think it changes anything if it is rooted or not.

have you tried to put back stock rom and see if your problem remains ?
[Galaxy S II Q&A, Help & Troubleshooting] diko adrian:
yes I have, I got stock CWM backup and nothing changes. .

How much do you think it will cost?

And could you be more specific with the parts that need to be replaced?
[Galaxy S II Q&A, Help & Troubleshooting] megosu:
I'm not a repair center :/

I have no idea what they did and how much would it cost... ask them, maybe they know type of defect and can give you a quotation.
[Galaxy S II Q&A, Help & Troubleshooting] diko adrian:
Thanks mate, should you cheers because your phone is back :D
[Galaxy S II Q&A, Help & Troubleshooting] pi-xel:
Hey guys,

Sorry for not answering for a longer period, was a few days off and had no time to stroll around on XDA :)

From my side there's nothing new, my phone is currently broken (hardware buttons are not working (cable torn) and with those disconnected I cannot boot my phone).

I have ordered a new set of hardware buttons + new USB connector, will replace those parts tomorrow and see whether it has any effect.

[MENTION=1194199]megosu[/MENTION]: Would be really great if you could find out what they repaired / exchanged to fix your battery life.
[Galaxy S II Q&A, Help & Troubleshooting] megosu:
I know, that's why I was a bit sad when I didn't receive any explanations from them... just a "Quality pass" form signed by the engineer.

but I have requested it ! so hopefully it will arrive and hopefully it won't be some random generic stuff like "replaced hardware parts" :)

any news mate?
[Galaxy S II Q&A, Help & Troubleshooting] dbrezancic:
Hello to everyone,

I read your stories ansd my is similar too...

About three months, suddenly, I had experienced battery draining…my phone didn’t last a 5-6 hours. I was on ICS 4.0.4.

So, I done factory reset…a little bit better: about 12-15h on idle. Of course, everything was off or at lowest settings (wifi, mobile data, screen, gps….etc.) draining of battery was about 6%/h even if I don’t a phone….if I used a phone (very little use) it was easy about 10%/h.

Then I upgraded to JB 4.1…same thing…it was still about 6%/h.

Then I rolled back to GB, than again ICS up to last JB…always the same results!!!! I had even rooted phone, used some custom ROMs…no luck at all.

I have read many posts on web…tried everything and nothing was helpful. The last thing I tried is power phone off during night…when I woke and powered up phone I had been shocked: from 100% to 20% over 9 or 10 hours!!!! (the same was with the new battery 2100mA but it was dropped to 50%).

At this point I was sure it’s something about hardware…..so after month of checking, trying…etc. I decided to take phone to service: factory reset, all of my settings as earlier, disable some software etc.

After sometime, they called me to get for the phone…reason was-software problem?!?!? I was skeptic about that but they done something and power drain was at 1, 6%/h (idle)!!!. I was really surprised: Much better than 6%/h. They said that had reinstalled software but I notice the didn’t: all of my settings were the same, all disable applications were the same…..

I have tested the phone with my new battery (2100mA Samsung) and drain was 1%/h (idle). Tested phone for a few days…it was good.

And then… I decided to factory reset it and the same problem appear!!!!!! 6%/h on idle!!!!

Of course they don’t want to tell what they done…but I think maybe they change some settings manually in some files or…no idea.

But one interesting thing was different when I picked up the phone. Before servicing, when I charge my phone it reach 100% charging and I have to wait a lot until (more than hour…maybe two…) see notification: battery full, remove charger.

But, when I got it from service-this issue not happened-when charging reach 100% I got notification battery full… very soon, almost immediately!!!

So, maybe this is something they checked, changed somewhere, somehow….

Here is attachment of BBS…from 26.4....

From then I rooted my phone again with new stock rom XWLSN, then rooted with siyah kernel 6.0b5, and... THE SAME abot 6% on idle. Today I was trying to make some changes using STweak (unfervolt cpu a little) but gained nothing.

so....
[Galaxy S II Q&A, Help & Troubleshooting] Karpfenhai:
Sorry mate, but this drain cannot be explained by your dump, if it persist even on flight mode... hardware issue..

Looks like a new system board ids necessary..

[Galaxy S II Q&A, Help & Troubleshooting] dbrezancic:
Thanks for reply..

If you read carefully the phone was at service and they fixed it.

Software issue. !!!!????
[Galaxy S II Q&A, Help & Troubleshooting] Karpfenhai:
I've read carefully, but I don't believe in software issue.. in flight mode with everything turned off the drain should be around 0.1 - 0.3 / hour, if it's not the case... hardware...

Did you try to clean and bend up your usb connector?

Tapatalked from my Galaxy SII
[Galaxy S II Q&A, Help & Troubleshooting] dbrezancic:
OK I see....I found similar issues here on this thread...

I thought it was hw issue so I went to the service, but .... they did not change any hw part ....but they done something and I had 1.6% drain on idle end even 1% with new battery....

I cleaned USB port....no luck
[Galaxy S II Q&A, Help & Troubleshooting] diko adrian:
maybe the usb ports?
[Galaxy S II Q&A, Help & Troubleshooting] dbrezancic:
They didn't change anything.....but somehow they fixed issue....

I have tested overnight with airplane mode on....and battery diagram shows some wake locks....

CPU spy shows more than 98% of deep sleep, BBS shows 1m and 30s max wake lock, some others too but times are so low...

I captured some screenshots I will upload it latter....

The phone is currently charging so I will do some tests again and make dump files with BBS....etc
[Galaxy S II Q&A, Help & Troubleshooting] dbrezancic:
here are some screen shots over nigt testing, airplane mode ON....

mayve someone see something here...

[Galaxy S II Q&A, Help & Troubleshooting] dbrezancic:
No comments on above... :crying:

so i made another one test today in airplane mode....4,6% drain....

again any thoughts will be nice...:confused:

[Galaxy S II Q&A, Help & Troubleshooting] megosu:
Hi,

IMO if you flash stock 4.0.4 with no root, no app and if you still have a big battery drain in airplane mode, then it is hardware. Pixel and myself have been through this already and have lost enough time without any result.
[Galaxy S II Q&A, Help & Troubleshooting] dbrezancic:
Hi,

I read and followed your posts, both of you....it was interesting to me, because it was basically the same issue....

As I said in my first post, #227 I have been tried GB ICS JB custom ROMs root-unroot...maybe I didnt make proper clean install ony that else could be..

But intersting thing is that phone was at service (because I have no ideas any more...) as I said, and they fixed it...sonehow but they didnt changeed any hw part(s)...It was software problem according to them. The phone was not rooted, just stock app ...etc.

My phone was god 1%/h mostly if you dont use them often-much better then 5-6%. When I done factory reset-issue returned!!!!

What did they do??? That is the question!

I think (maybe it is silly) but....

There were file in GS3 called power_xxxxxx.xml and its about battery data (you can google on it)...it was a bug in that file in one version of android so the battery was drained quickly!!!!

So ...I think, maybe there some file(s) in GS2 too, with data for battery charging, draining ....etc...

At last I will send phone again at service (still in varanty) and ask to explain/write to me what is wrong...if they wont to do it :)

Hi guys,

Long time!

I brought my phone to a cell phone repair center here in Dallas on Saturday. When I called today the guy was working on it, but he thought he could fix it. I'll ask him what was wrong, and check tonight if it is actually fixed. If it's anything that could help you guys I'll post it here.

Didn't sent it to Samsung as my warranty will probably be expired. And I rooted and did all that kinds of things (just to solve this :(). Probably should have sent it in right away. Well, I would be happy to pay 50/60$ if it's fixed now.

if you have tried all the above, then welcome to the club.... it is hardware and your phone needs to be sent to the repair service.

Hey guys,

Sorry that I did not respond earlier, my phone is currently broken as I damaged my LCD during my last repair attempt. Currently waiting for a new screen from HK, then I'll come back to the game :)

However, I've just read the last pages and tried to catch up what happened here since I wrote the last time. I don't know whether I remember it correctly, but the point that dbrezancic makes is interesting to me, the one regarding the battery full notification:

I don't know about which notification he is actually talking, but as far as I remember, when the phone is turned off and fully charged, the green battery icon on the screen should show a completely charged battery (correct me if I am wrong, might be that I remember this from another phone). On my phone this battery icon was not shown as charged completely for a long time.

Could you tell me / us what kind of animation / picture you see when you're phone is fully charged when turned off? (Maybe attach some pics)

And [MENTION=4355376]Karpfenhai[/MENTION]: Do you know which piece of software is responsible for controlling the charging procedure (including the phone off charging animation)? It should be neither kernel nor rom or radio as neither of those is accessed when turned off, so my guess is that it's part of bootloader(?)

Might it be that we do have a software issue in the end?
[Galaxy S II Q&A, Help & Troubleshooting] Karpfenhai:
Download mode and "switched off charging" is hardcoded in bootloader - it is closed source so only option is disassemble it (if you have proper knowledge).. but.. flashing a new bootloader might help then.. what you guys have already tried..

[Galaxy S II Q&A, Help & Troubleshooting] pi-xel:
Alright, this is what I've expected.

At least I have already tried out several bootloaders, so the only possibility I see regarding a software bug is that the bootloader itself uses some external configuration files for the charging procedure.

And such low level code is at least unlikely to read some external files (from some partitions, eg. EFS that is afaik the only partition that is not changed at all during flashes) as it should not even have the capability to mount partitions...right?

Already taken many more risks than flashing a bootloader (and paid for it with my touchscreen), but thanks for the warning anyway :)
[Galaxy S II Q&A, Help & Troubleshooting] dbrezancic:
glad you are back, but sorry about broken lcd

As I mentioned earlier, my phone was at service because I had tried everything I could ....I was sure about hardware problem...

I was wrong ...they done something and reduced my power consumption from 4-5% to 1,3-1,5%...big difference

I was talking about charging...the one and only thing I noticed it was different when I picked up my phone...

- When chargigng process reached 100% i got notification immidiatelly-fully charged, unplug charger- and grreen notification icon in left corner

- Similar, when charged phone off I got green icon 100% immidiatelly.

This was not the case before I sent my phone to service. I had to wait hour and even more ahter reached 100% charging, for fully notification note and icon.

But when I done factory reset, the same simptoms were back 4-5% draining. And I was started to wondering is there any file regarding to batt charging?!?!?!

According to answer I read latter in this thread it could be something with bootloader. I didnt flash any until now...its is something I will try...

But, I have some big improvements...still trying

I have rooted my phone again, downloaded script for wiping my ROM (GS2ROMNukeV2.10.zip). I found it here on xda I suppose, but I dont know link now...

So I copied script to sd card, rebooted my phone in CWM recovery, erased everything I colud then run the script...

Downloaded latest stock ROM XWLSS (XEU) and innstalled it via ODIN...Consumption was about 1,7% -2% ...much better but not good I suppose

I rooted my phone again yesterday, using some STweaks (default cpu section+undervolt 50mV), and battery mode (syjah kernel) and: 15 hours ON, 77% batt cca 1,5%

So....maybe some bootloader could make this better?!?!?!!?
