Help Battery failure.

[dragev333]

Well here is the problem..
I put my charger into my Galaxy note.. charge it to 100% take the charger out.. and suddenly i hear a sound about 2 minutes after the charger is out.
that sound is the sound that you hear when you plug the charget into the phone. so when its not charging.. the phone says it is charing.. and when its charging the phone says its not..

another problem is that if i dont have my charger in the phone when i start it up, it wont start.. it just goes "charging - not charging - charging - not charging" when the phone is off.

i tried to take out the battery and let it stay out for 10 minutes, put it back in, no help.
all these problems started after the ICS update a week ago.
also the battery drains in just 1-2 hours of use (internett, a game or anything)
or about 10 hours when the phone is "sleeping" it drains to about 10%

i downloaded cpu spy and it says:

1200 MHz: 0:09:40 4%
1000 MHz 0:01:44 0%
800 MHz 0:01:13 0%
500 MHz 0:02:35 1%
200 MHz 3:22:09 91%
Deep Sleep 0:03:06 1%

Unused CPU states: 1400 MHz
Total time state 3:40:31


i also downloaded a program to check my battery called Better Battery Stats that i paid about $2 for.

at the start i had a program taking 99% battery non stop, that dissapeared when i removed my battery for a few minutes.

my problem now is the
"USB cb wake lock"
"vbus_present"
^both taking 93,7%

and Power manager service taking 51,7%


Honestly i'd love to hear how to fix my Battery Drain problem and my Charging problem.

Thanks in advance.
VM.

It does not look like this was ever resolved, so figured I would chime in since I have been looking at this for a while.

If you use a charger which is compatible with Apple products, it will cause the vbus_present wakelock since Apple does not adhere to USB standards and requires two of the pins to be bridged or open (can't remember which) to work for their products. However, when you charge a device that does adhere to USB standards with one of these chargers, it will cause the wakelock (on all the samsung phones I have seen, anyway).

Another downside to using an apple compatible charger is that you can never get more than 500ma out of it due to the non-standard USB connection, even if the charger is capable of 2000ma output. So you get slower charging.

When you are connected to any charger, this wakelock will be present. If you use an Apple compatible charger, it will persist after you unplug it and will drain your battery around 10% per hour since it prevents it from going into deep sleep. You can clear the wakelock by rebooting the phone or plugging it into a standard USB charger, such as a PC or Samsung charger, even for a few seconds.

You can use Better Battery Stats to see the effects of this wakelock. Note that it can take a few minutes to show up once you have unplugged from the apple charger.

Yes, this really p*sses me off. This is one of the reasons I no longer have any Apple products in my house and long since thrown away all the Apple compatible wall chargers I once had. It still comes back to bite me since I still have a couple of chargers that contain batteries to charge when you are away from a wall outlet and they both cause this. When I use them I just have to make sure I reboot afterward. The USB outlet I have installed behind the stereo in my car also causes this wakelock. I have one to replace it but have not gotten around to removing the stereo to do this yet.

The next best solution to never using an apple compatible charger at this point would be to have a kernel that addresses this and removes the wakelock after it is unplugged but I don't see this happening.

I manged to get this fixed.. i sendt it back to the place where i bought my phone, they sendt it to samsung's repair factory place, and they did some tests and cleaned up the battery, and i don't know how but what ever they did it worked. my phone is working 100% again now.
didn't pay anything either since it was a technical error.
