What this com.qualcomm.qcrilmsgtunnel does. I stopped it service and process nothing really happened. I restarted the phone and it is back running. Anybody know what this app does. My phone is Nexus 5, 4.4.3.

  • This process eats my battery faster than anything else on the phone. Whenever my battery seems to be dropping faster than usual, sure enough this process is running. I pop into developer tools / services and kill it. It doesn't seem to have any other impact on the phone except draining the battery. Commented Feb 14, 2023 at 17:59
