Android Enthusiasts Stack Exchange is a question and answer site for enthusiasts and power users of the Android operating system. It's 100% free, no registration required.

I was wondering if there is a system monitor app that will raise (audible) alerts and offer app closure if it detects runaway threads on Android that cause physical overheating and battery drain.

E.g., I just had to turn my phone off because there was a runaway thread that I think was constantly trying to refresh FB where there was very poor connection, so it was going in a virtually endless loop. But I get that with other apps too and not just Facebook.

I'd like to actually shut apps down when they're detected.

I am not kidding, I nearly burned my fingertips when I touched my phone -- it was on for only 2 hrs and the battery was almost dead. It is because 4G is very poor inside my office building and I checked Facebook walking between my vehicle and the building this AM. After that, the app kept trying to refresh continuously without success and overheating the phone.

Apps may drain your battery, but they should never cause a device to overheat. If you experience overheating there might be a different, physical defect with the device. –  user4188 Oct 25 '12 at 21:50

As noted in the comment, "battery drain" and "overheating" are not necessarily connected: not everything that drains your battery causes overheating. Overheating is most likely caused by excessive CPU hogging (which of course also leads to battery drain).

You might want to take a look at the app DrainGuard, which keeps a log of battery consumption, always informs you how much was consumed since you turned the screen off last time, and -- here it comes -- it can start an alarm when some app causes excessive battery drain. Values are configurable:

DrainGuard Alarm Config Drainguard Alarm

The free version only works from 100% charge down to 70%, which is fine for testing. Once you decided the app serves your purpose, the DrainGuard PRO Key is available on the playstore for less than an Euro.
