RILJ keeps phone awake, what else can I try?



A few months ago my phone's battery started draining twice as fast as it used to. At first I replaced my 3 year old battery, but that didn't help. So I rooted the phone and installed the recommended apps, which marked smdcntl1 and radio-interface as the culprits. I then s-offed the thing and tried a few combinations of ROMs: stock, Liberty 6th element and CM12.1; and radios: 1.15, 1.20 and 1.35a.

Once I moved from the stock configuration, the results are the same - the phone is awake 100% of the time, and now RILJ is reported as the villain (this might have been the case before the rooting too - don't remember, and I might have used less capable tools).

I have the location services off and so is the GPS, wifi and bluetooth; I don't use any social network (cr)apps; and I'm a very light user in general. My reception is ok, but the drain continues even during the night. I tried to block wakeups using Amplify and force deep sleep using Deep Sleep Battery Saver - neither made any difference. The only thing that lets the phone deep sleep is flight mode.

I'm now out of ideas. How can the insomnia persist over different roms and radios? What else can I try?
