CPU Spy is a simple app that allows you to monitor your CPU usage
This is just an app for monitoring, you can't modify nor your CPU frequency either any other parameter. You can check how much time CPU spends in each frequency state. Your CPU isn't always at highest performance: its frequency varies depending on the process you're executing. For example, you're in lower CPU frequency when airplane mode than over WiFi. You're in the lowest CPU frequency levels when, what's more, display is off.
CPU Spy shows 6 states: 1000Mhz, 800Mhz, 400Mhz, 200Mhz, 100Mhz and deep sleep. What's more it sows how many time you spend in each frequency and how much it represents out of the total. It also shows total state time and kernel info. You can reset/restore timers anytime.
In summary, an useful tool to keep track of what's going on your device's heart. Recommendable.
It also displays the current kernel information.

Let's you keep track on cpu usage and deep sleep. .. If you have issues with battery. .. This would be your first place to start. .. Keep track of what cpu is cycling at and figure out what's causing issues
Does what it says on the tin.
Excellent little handy app for checking on your phone behavior. Can help you notice if you have some apps hanging in the memory and hogging the phone resources and battery power.
Works exactly as expected,now I can finally have a better look at the deep sleep problems my Android device is having
Which is not much there are better tools out there that do this plus much more.
Helpful and simple app.
Simple, straightforward and useful!
