CPU Spy

Still works great for seeing if you've got a wakelock issue even though it's been a decade since the last update. Apparently it only sees the clock of the "little" cores, but I believe deep sleep for them means for all cores. A recompile on modern Android for security's sake would be nice even if the BIG.little core thing goes unaddressed.

It only shows stats of little cluster cores, many SoCs use big.LITLLE architecture and big cores use different frequencies than little ones.

Built for old Android versions. Not updated since 2011

Atill one of tge best apps, does exactly what is in tge description.

Does what it's supposed to do and nothing else. Exactly what you'd expect from a 28kb app.

No bloat, does what it's supposed to

This app had always helped me to identify battery drain issues at first level. If your phone doesn't get to deep sleep mode,there's some issue for sure. I've identified a few such apps and uninstalled them and now the battery life is much better. Though there are lot of battery saver apps, this app is something which an user will need at any point in time when he wants to debug battery drain issue.

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.

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.

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. :)

You know Google at some point you're going to lose all your 'friends' when the market gets tired of your scam with Samsung. Hopefully an enterprising ethical company will step in with a device that operates with a lot more integrity. To coin a phrase "just sayin", enjoy it while you can cuz even OS challenged individuals like myself eventually figure out why they use 30 GB just playing Candy Crush.

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.

This app helped me get decent battery life out of my early version Vibrant and its bad GPS vs. Deep Sleep issues. Extremely helpful to know if my phone is sleeping peacefully or not.

Great, yet simple software that enables one to see if the much desired deep sleep is being achieved, and what frequencies is the phone CPU frequenting. Very useful as a first step in detecting causes of excessice battery drain.

Very handy program, a must have if you need to know if your phone is deep sleeping to save battery.

If you have battery problems, this app can help you diagnose it. If your phone is off for a few hours it should go into deep sleep for those hours you don't use it. If it does not, you have a problem. This app will allow you to see that.

Precise, very helpful to check out device behavior while it is in the pocket. It would be great if you could add logs or list with apps which are using CPU while the phone is in sleep mode...

This did not work on my T-Mobile HTC Sensation. I am running ICS. Sorry for the 1 star, but not good if it does not work.

I have an 8 core note 3 with 1.9 Ghz clock, and the app says the phone uses only 650Mhz max clock speed...

Quite useful for diagnosing battery issues. With this app I was able to quickly identify that my N7 was not going into deep sleep on standby.

great for what i need. would be convenient to have the app show which process is making it stay awake, but that is not a big deal. bbs does that and this does what it needs to. thanks!

Helped me see if my sleep issues were solved, keeping it around just in case I get more issues.

Perfect for those of us that like to have full control over our phones. I keep an eye out on everything with this app and its a phone saver for sure.

Great for debugging kernel and battery issues. This app has never let me down. Highly recommend... I would definitely pay for this but it is free lol

in my opinion this CPU application is the best. it really shows all of your different CPU speeds and how often each speed is used. an excellent CPU application that tells it like it is.
