I have the issue where the baseband xmm power wakelock keeps my phone from sleeping much at all. I have read so many threads and information on this but still am not any wiser.
This happened on stock as well as CM 10.2 and Viper X 4.0.6 which I am on now. As soon as I disable wifi even without rebooting the wakelock massively reduces. To reproduce this issue all I have to do is turn off the screen and the wakelock counter will go up. As an interesting point when I do disable it the deleted wakelocks show a very high number in BBS but my battery life is tons better.
I have tried all the normal things like disabling/uninstalling/factory resetting. Am I correct in believing this is to do with the kernel or wifi driver? If so which do you suggest I try or what can I do about it. I don't think it is my router as it happens at both work and at home.
Any advice appreciated. This has taken up so much of my time and is so frustrating.
