Even a small amount of power over three days will be noticed.

You aren't sneaky enough. You are going to trust the battery level
the phone is telling you about? The same phone that someone has
hacked and presumably put in some ways to convince you it isn't
hacked?

A more clever approach, for those folks that watch the battery level
might be to report 100% then just ramp down to the correct capacity
while the phone is in use and you expect it to go down...

that won't work for a variety of reasons.



You wouldn't know if a background program was running.

Yes, I would. I check every now and again.

You check what the phone is telling you... by definition a background
program does not announce itself - it wouldn't be in the background if
it did, it would be in the foreground.

yet another thing you don't understand.
