Flawless app!! I've been using it for quite some time now. It's works really well and does let me know, if they are any apps which might be interfering or preventing the phone from going into Deep sleep mode, when the device is not in use. ( Please note that this app does not pinpoint those particular stealthy apps). The information it provides is accurate enough. Works like a charm. Thank you so much Developer/team. :)

Great app Would be far more useful to me if it reset timers on unplug as my phone doesn't sleep while plugged in. I believe most phones work this way so I'm not sure why there isn't an option for it. Other than that, works perfectly. Guess ill keep manually resetting when I'm done charging.

This newbie loves it I was able to see that something was chewing through my battery and my phone wasn't deep sleeping the way it should. But since I am a newbie and someone who for medical reasons is unable to learn another facet of the computer/electronics field, I have a favor to ask. Is it possible for you to list the likely apps or phone functions that run at each frequency? I had my phone running in deep sleep quite well, but now either I have added a new one that runs a lot or I use one a lot more now. I want to find it.

Won't work on stock HTC kernels Although CPU Spy needs a rooted HTC phone, it also requires custom ROMs with non stock HTC kernel for it to read the CPU states. Unfortunately stock HTC kernels don't supply this information for CPU Spy to read from, so unless you've flashed your phone or tablet with a custom kernel, don't blame the developer if doesn't work. CPU Spy works fine with my previous HTC Incredible S and Flyer P510e with custom ROMs, but not with leaked or official ICS Android OS that use original HTC kernels.

If you root you need this! As phones chew power its vital to monnitor the changes we make with custom kernels. What I like about this is it shows how long my phone spends in deep sleep. Some kernels stop this, so you need to see wtf is going on in there. Basic, well out together app. which doe's just what it says. Good to use with "no thrills CPU control ". You can get a primo set up, with a bit of monnitering & adjusting! HowardBamber.

Incompatible with stock EVO 3D(ICS) While this app can't read the states file on a stock EVO 3D running ICS(4.0.3), it works great on kernels/roms that it is compatible with. My issue is due to my ROM/kernel, not the app itself. But those of you using E3D's, keep this in mind.
