On my Android phone (Sony Xperia Z3 Compact), I have a situation where it sometimes goes very sluggish, and the battery drains quickly.
This seems to happen after roughly once a day, and lasts until I restart the phone.
I haven't been able to get any useful info out of the battery info in settings, although the %s there sum to quite a bit less than 100%, so I'm concerned there is some dodgy system process killing my phone.
Is there any way I can get a list of all processes and current cpu usage? I've had a look in the play store but not found any apps that can do this.
