Sorry about phone/OS version. I was hoping someone would point me to an Android OS task manager or process analyser which might be capable of telling which processes are going to keep part of the phone "more awake" than it should be when asleep.
I actually put "code downgrade" as in my experience every time a computer takes what is called an OS download it ends up slower and more bloated than before.
The phone is a Galaxy S3, two months old, which has downloaded a new OS twice now. It is running Android 4.1.2. The only Apps I have installed are the aforementioned TV guide and the Android version of Free42, a working emulation of a RPN HP programmable calculator. A few of the standard load Apps have seen fit to load newer versions than originals.
