So I was looking in my Google maps app for a couple of minutes then my notification bar randomly popped up saying task manager alert with a percentage going up and down ranging between 70 and 95% CPU usage. I find that amount to be an extreme amount of CPU usage. I click on the notification and it brings me to my list of running applications and there is about 7 running applications with a small amount of memory usage which I find normal because this is the settings automatically remembered for the phone to run these particular apps smoother.....but next to the list of running apps the CPU usage for each one said 0%.......I'm concerned with what that task manager alert means....if you have had experience with this help would be appreciated thank you.
