Thanks MP for donating so much time for everyone else's benefit. Hopefully when you get the spare time to do some developing again you'll have the itch to improve our awesome sgs3. Hope all goes well for you.
Krickies!!! Skip a couple of days and you miss all kinds of things. My bad man. I saw and we talked in the Lounge but it didn't dawn on me that there was more to it in this thread. Anyways, I appreciate all that you have done and hope that things go well. Remember that just because you aren't working on the kernels and moved on to another full time device, you are always more than welcome to stop by and chat for a bit.
You are part of something special that happened over here and just because some have moved on doesn't mean that it is over. Hope the family is ok and be easy my friend.
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.
