Are you sure its not just the battery getting old?
I know a lot of phones do take significant current on gps and some
monitoring tasks.

Said smartphone is a Samsung Galaxy Ace2.

Previously if I eft home with it 100% charged it would last all day, maybe
dropping to 40% charged by the time I got home.

For the past week its been dropping to 30% or less by around 3pm.

Something is clearly running in the background & using up battery power,
any idea what?
