CPU tuner (Rooted phones)

Finally found it and after using it for a few days I've been give prob an extra of 30% of more life but wait I was on power save what about extreme power save lol, ur a champ mate the created of the app, thanks heap using my nexus 7 2013 (flo) paranoid 4.1 beta1

I've been looking for a tool like this for ever. It helps battery life quite a bit. Especially if you take the time to really customize the profiles for your usage patterns. As of this writing, It doesn't seem to be able deal with enabling/disabling lte on my phone, but otherwise fantastic.

Up until recently, this app would work very well, but now, it doesn't switch out of auto: screen off like it should. I'd rather not leave it on normal all the time. It defeats the purpose of having the app. Auto was a good feature. Now, not so much. Edit: disregard the earlier statement. It still works. I had to change a setting in the app to accommodate for a setting I set on my device. Actually, it's a great app. Works flawlessly, if you know what to change. Thanks to the dev.

Excellent app. I love that you can choose from several default configurations. That makes it easy to try different things with your CPU and the governors. Fortunately the default configuration is your current configuration, so they won't screw up your entire system. The thing to remember is you need to change the default configurations to match whatever tweaking that you would like to do.

Amazing. This does everything I was looking for for cpu profiles. Takes a bit to setup but all and all great. If there was one thing I would like to see changed it is as follows. Wish my cpu frequencys where setup by default. I had to manually put them in. I had just the highest and lowest frequencys as options originally in the app. I had to manually set the frequency in between. Using sony experia play.

I tried "Simple and Powerful" profile, the CPU ran at 2GHz, within 2 minutes my phone crashed and stuck in boot loop. Dangerous profiles should not be easily accessible and give some warning. Also it should not set CPU profile on boot by default, in case something goes wrong we restart the phone to resume the safe profile.

I usually unplug my tablet around 5am. I read some G+, some Reddit and some Feedly. By 6am I am out the door and head to work. Here my tablet pretty much sits on my desk until noon, though I will I usually check emails throughout the morning. Before this app I'd already be at 50% at noon with this app I am currently sitting at 60% and its almost 3pm! Huge battery increase without sacrificing usability.

I have noticeable improvements in terms of standby when using this on my rooted android, this is evident when the screen is turned off as it minimises the cpu usage and takes very little battery over a long period, this allows me to enjoy longer screen times and standby, now I get almost 6 hours screen in an 19 hour period before the battery dies, where's as before I got 12 hours standby and about 4-5 screen time, so a definite improvement. Well done developers

My Nexus 10 tablet suffered from some lag when I had opened man windows. With this tool I could analyze that it was running below 1000Mhz quite often. I tuned it ti use between 1000 and 1700 when it is cnnected to power and battery over 75% and it is really like I have bought a new device :) Sadl I cannot overclock, but I am running stock 4.4.4 and so it's not the apps fault.

I love the design and concept of this app, but recently after an OS update (cm12.1) my phone has begun randomly freezing and the rebooting. I started removing apps one by one to test what is causing it, and it stopped when I removed this app. I love this app before and how much battery it saved and I really hope that the Dev can resolve this cm and lollipop (5.1.1) area issue so I can use it again!

..based on its simplicity and performance. Lately SETCPU (because paid for it previously) seems no longer functioning up to mark because it's profile no longer switches. Changed to this, and presto, my underclocking at screen off and on works like a charm. Keep up the good work developer

I was about to give up on my phone it kept over heating even after buying a new battery , the other cooling apps don't work and I really didn't think this one would either , but it works great my phone is cool to the touch and only gets slightly warm even with heavy use , I would gladly pay money for this app if it wasn't free😄

This app is the greatest except for one issue. All my profiles has the cpu frequency above 1200mhz, but after an hour or so the cpu drops to either 800mhz or 1000mhz. I could is this in the log. I have to disable cpu tuner in the setting and enable it to have the cpu reset to the correct frequency. I am on a rooted SGN2.

After choosing the 'sophisticated' setting my phone (sm-n7505) imideatly got stuck in an infinite reboot loop. Aparantly the CPU couldn't handle the setting it was forced into. Had to wipe all data in recovery mode to get my phone back to a working condition. So now I kinda hate the app...

Really allows you to have your cake and eat it. Using the virtual governors with speed settings I chose for when the screen is on/off has really made my power use more efficient whilst giving me full power when I need it. Still haven't found out how to by the dev a whisky yet though, when I do he will be drunk!

I'm not a pro at this. The profiles, and a little bit of reading, and you can get a great understanding of saving battery life. I love performance, but I hate charging all the time. So a happy medium is a must for me. I use the normal setting, and since I set it up to power save evenly from full battery to empty, my phone not only is obviously saving battery, It seems much smoother surprisingly. I can't see why anyone would give this app a poor rating. Thank you for the excellent app developers!

Works well, can't say it's without it's problems sometimes governors aren't being set right, I think it's a flaw in my devices firmware rather then the app.. but it works well otherwise. This is great for tuning down your cpu to try and save some battery life. A cool feature to add would be if it could trigger based on which app is in the foreground so say you open up an app it would automatically apply a specific profile while that particular app is in use. Plauge inc for example will gobble up my cpu and battery for some reason, so I always put a cap on the cpu speed and cores with this before playing.. wish cpu tuner could do this for me automatically.

Nice way to set profiles, and triggers to activate them, good UI too. However, I tried to check if it uses only one core of my cpu when I ask it to, while in screen off mode it does use only one core but while my screen is on it uses as many cores as it pleases, even if I have screen on profile set to use only one core. Why is it so? Also, charging takes a lot of time if this app is enabled. Please fix these issues.

It works well but the trigger is not being enabled sometimes.other than that,i can shut down 6 cores out of 8 in my phone.npw my k3 note lasts longer.A very big difference.

FC issue needs fixing. Widget don't work. Ask for widget extension,go to store and CPU tuner FC. Very buggy. Running on note 3 - 4.4.2 assassin Rom. Tried various kernels too. Accurate CPU control for 85% of the time. But very good for controlling battery use. There's a widget option but no widget.

I like this app because not only can I increase/decrease voltage, but I can enable and disable it. Something I could not do with no-frills CPU. It also seems easier to understand and more user friendly.

Best ever android app I used for power saving. I was frustrated with my new xperia sola. Battery was not lasting even 18 hours. It was consuming around 35% battery over night. That too with out any data connection. I was thinking about changing to a windows phone. Almost all battery savers in google play was useless for me. As a last try, rooted my phone and installed CPU tuner. Wonderful results:) now my fone consumes only 5% over night. Battery lasts one and day wit heavy usage. Hats off to Dev.
