One Application Always Running-How To Find Application?

[123spongebob123]

I always use device care. Seems like battery draining quicker. When use device care when click on battery-usually always at 100%--last 3 weeks at 99% and says 1 program closed.
How can I find out what that program is?
Appreciated assistance, thanks

If it's closed, that means it's not running, so you can't. (If you unplug the charger right after it reaches 100%, it will be at 99% or even 98%. The charger being plugged in throws the reading off a little. But don't leave the charger in too long - if the chip in the phone goes bad, it could cook the battery and kill it. Besides, the amount of time to go from 99% to 50% [which is where you should start looking for a place to plug in the charger] and 100% to 50% is only going to be a few minutes if you're using the phone for anything.)
