Hello everyone. We all know about the built-in privacy guard in CM11S, CM12 or roms based on these for our devices. If you don't know then I would like to mention that it is an app which helps in managing permissions for apps like which app is allowed to wake up or keep awake the device, which app can acess our contacts, etc.
There are a number of threads on xda about an Android OS battery drain issue and the fix for it is denying wake permission for it from privacy guard. I didn't have the Android OS issue and rguarly got around 5hours of SOT but still I did the denying wake permissions thing. It made a small difference and my SOT improved (I know SOT is not a perfect measurement of battery stats but I am just using it for the sake of giving you an idea). I then went forward and denied permissions for most user apps installed on my device as per my requirement (without breaking functionality). Now I have the privacy guard message active for most apps I use and I have seen a fall in my battery life to 5hours SOT per charge and now I have even started getting android OS on the top few in stats. No new apps have been installed during the course of the test.
My question now is that is it possible that the privacy guard now remains active for most apps trying to block it from accessing whatever permissions I have disabled for it and in turn eating up more battery than all these apps combined used to? I am obviously going to do my own tests by resetting privacy guard to default too but I thought of asking fellow XDAians too about what they think about this.
