Runaway Android apps

[UPDATE June 5, 2014] Multiple observations confirm: Instagram (which behaves (mostly) properly on Wi-Fi connections) becomes a CPU hog on carrier (cellular) connections. Not sure why, will report here if I find out more.

[UPDATE June 2, 2014] In an effort to gain a better understanding of what’s going on inside my Nexus 4, I installed two utility apps:  and . Lookout scans and monitors for malware, and offers a bunch of other security features; Watchdog alerts me when an app exceeds a certain CPU threshold.

First impressions are great. Phone runs cool. Interesting observation: When I kill Instagram — the worst offender — through Watchdog, it stays dead. By comparison, when I used to force-stop Instagram via the Android device (system) settings, it would often start up again right away by itself.

My phone (Google Nexus 4) has been getting really hot lately, draining the battery in the process. I started monitoring running Android processes and services, and found out that several apps sometimes don’t close when I tell them to, but keep running and consuming CPU cycles and battery juice. The biggest offender is Instagram, followed by Facebook (which starts on boot and keeps running (and restarts itself after a force-stop, the nerve!)), Google Play Music (which seems to randomly start itself on a whim, or possibly gets launched by Google Drive), and MailDroid (as ).

[UPDATE May 17, 2014] Adding Snapchat to the list of runaway apps that must be force-stopped after every use.

My response:

  • Remove the Facebook app, which I have been threatening to do for a while. I am not leaving Facebook, just removing the app from my phone.
  • Scale back the use of the Instagram app, and force-stop the app after each use.
  • Scale back the use of the Google Drive app, and force-stop Google Play Music after each use (confirm cause-and-effect).
    • [UPDATE from a ]: “Google support told me to uncheck the box Settings > Accounts > Google > Accounts > [myemail]@gmail.com > Sync Google Play Music. I had sync checked before the update as well, but it caused no problems. In any event, this didn’t do all that much good. The app is like the freakin’ Terminator — force stops won’t kill it.”
    • [UPDATE from A.T.]: Disabled Google Play Music. Problem solved.
    • [UPDATE from A.T.]: Also wiped a ton of other Google shit off my phone. It felt great.
  • Stay away from the MailDroid app.
  • Monitor Android system activity regularly for runaway apps and force-stop them as needed.
  • Reboot my phone daily.
