Thank you for the warm welcome 94lt1, Sydman and SallyC. Critical Care Nursing huh? Man, talk about a stressful job! Well, I'm in the pharma business so I make the drugs that you used to dispense.
After one short day of testing, here are some additional data points. I still have yet to give Open Signals some time to see what I can discover with it. However, I am glad to report that I may have "solved" the problem in my case but sadly don't have the root cause yet (research continues). So last evening, I created another Smart Action and charged up the battery to 100%. I created the Home action where if the GPS detects that I'm home, it shuts off data via cellular since I'm on WiFi anyway. Guess, what? No RILD (well, kind of, read on) and my battery went down only 8% over night. I do have an Overnight action where I shut down most services from 11pm to 6:30am every day.
Before I had this RILD problem, overnight battery drain was typically 10%, now it's 8% - even better! I am going to continue to keep this Home action for the next few days and see if the excellent pattern continues and if RILD comes back.
Now RILD did not show up in the Settings-Battery Information but it did appear with GSAM (formerly Bad Ass Battery Monitor). It shows that it used 0.5%, far less than the typical 10%+ when it was a run away process. Before I went to bed last night, I checked GSAM and RILD showed a 0.2% usage. So overnight it gained another 0.3%, not bad. And my phone has been full on since 6:30am (it's now 9am) when the Overnight action stopped. I doubt that RILD will ramp up again. The pattern that I have detected in the past is if you get rid of it with which ever method you want, it gets reactivated within the hour.
Taking a step back, before I implemented the Home action, I tried a power on/off, clear cache and soft boot (don't remember the order) and got rid of RILD but it came back within the hour and was climbing the % usage chart, quickly catching up to the top process.
SallyC, I have one question for you to clear up a statement you made below. When you said that WiFi didn't help you, did you turn off cellular DATA? Once I turned off cellular data, I no longer had 4G LTE (or 3G) but my phone worked as normal for voice. And since it still works normally for voice with my Home action, I think it's the data portion of the signal that is giving me my RILD problem. Once I realized that turning off cellular data didn't afftect voice and I have WiFi at home, it didn't matter to me then if I see the 4G or 3G on the status bar.
I will be running back and forth today helping my brother-in-law move in the next town over. It will be interesting to see what my phone usage looks like at the end of the day.
I will report back. Hope I'm not boring you folks with my experience.
