CPUinfo and CPU clock speed

So I want something that can keep track of CPU clock speed over a period of time. Specifically when the screen was off. I asked around and no really had a good solution.
Being new to android but old to linux, I figured I could just make a script that would check /proc/cpuinfo and every couple of seconds and save it to a text file. Simple....I thought.
CPUinfo on my phone (HTC Incredible) doesn't show processor speed.
Anyone know of a way to accomplish what I want? Maybe there is an app out already that will do what I wish, but I haven't been able to find one.

No one? There has to be some way to do this.

I know nothing about android, but I do know that setCPU shows the current CPU speed. Might want to look into how he does it?

Try looking in the market for an app called system or system panel that might be what your looking for
Root-Hack-Mod-Always™

I have System Panel but it only shows the current CPU clock and the full version will show CPU usage but not the clock speed.

you can try temp+cpu from market, it show the cpu clock speed, cpu usage, bettary temp & available ram in a 1x1 widget

That shows current CPU clock. I can't believe there isn't an app for this already. There are tons that show current but none that do any sort of logging.

I'm going to keep bumping this until I can get an answer. haha

[Q] I need help with my tablet draining battery too quickly

Hi, I'm having a serious issue here. I unplugged my Transformer from my charger about about 11am today. I have used it, according to the screen on time in the settings, for 34 minutes. (it's now about twelve hours later.) However, the battery life is at 64%. I just don't understand this. My wi-fi is set to disconnect when screen turns off, and brightness is at about 55-60%. But look at this.

Does anybody have a clue what could be going on? If you need more information about what state it is in, I'll be glad to provide more details. It seems like this started after I updated to 3.2, but that could be unrelated.

After updating did you set up the wifi power saving again? There is a bug in android where this setting gets reset when the device is rebooted

Yeah, I double checked when I posted this and it was still on "when screen turns off".

Try using juice defender. And check your running services/applications/auto sync cuz i see there alot of wifi actifity and your device is awaken even though the screen is off.

You could try using an app called Sysem Panel by NextApp.
You will need the paid version so that you can turn on the Monitoring option in the settings - this allows you to monitor the CPU usage over 2h/8h/1d/3d.
You can also monitor Top App usage of CPU which is fantastic for identifying the culprit.

Battery issues

So I'm running the 7/15 CM9 rom and today my battery is draining at an alarming rate. The highest percentage isn't even screen its phone? File attached. What is up with this? I've made one 2 minute call ALL day and sent about 20 text messages.

Have you tried InstigatorX's kernel http://forum.xda-developers.com/showthread.php?t=1721235 I've heard that it gives great battery life.
I would ask this in the CM9 thread in the general section http://forum.xda-developers.com/showthread.php?t=1710289 if that doesn't help.

It could be wakelock issues, try to use BetterBatteryStats to monitor the phone's usage. It'll tell you which program or service is using battery. Could also try rebooting. When the phone doesn't go to deepsleep it stays on a specific frequency (CPU) and slowly drains battery. Programs can also cause draining if they're constantly syncing and using mid frequencies rather than low level frequency. Each frequency level (192MHz, 1GHz, 1.5GHz) has different voltages so if it stays at a specific frequency it can drain a lot. CPUSpy is also a simple program that monitors how much time the phone stays at a specific frequency. If your phone has been on for 8hours and 7hours is on deepsleep then there is no wake issues. If it says 8hours and 5minutes is on deep sleep but 384MHz (or any) and you don't have any programs on then you have wake issues or a service is constantly using your resources.

help lowering phone wakes?

so after getting a custom rom and kernel and making some other changes, im getting pretty good battery life from my phone, well in comparison to what it used to be, but ithink it can still be better. especially considering how often apps keep waking my phone up. using GSAM battery stats, i am seeing the number of times apps woke up my phone today...
so many apps in the double digits!!
google services is the biggest offender, and when i click on it, it says that Google Contacts Sync is what causes it..should i uncheck contacts from the sync options in the settings menu? if i do that, it will also not save any changes i make to numbers from my phone though right?
and then next is go sms pro..which i have no idea keeps waking up, i only got 1 text today...
it seems ironic that juicedefender is in the top 3 since its supposed to be saving me battery..is it actually useful and am i just overthinking it?
then some of the other ones lik tv show favs and tweetdeck, i dont know what they are doing when they wake either. especially since in the tweetdeck settings i have it set to only update when i manually refresh...
any ideas or solutions to bring those numbers down?

Any ideas?

Here's some tips for balance of speed and battery life! (Works very well)

First of all, download an app called "Setxperia" , go to your cpu settings and set your governor to ondemand, and threshold to 40 (This gives responsiveness and speed comparable to higher end phones such as my galaxy s2). Second, download an app called "Deep sleep battery saver" , set the preset on any you want (I recommend strong) , set your screen on and off delay to 5 seconds. For battery discharge settings, set it to 10% , for recharge settings, press ignore. (Doing this compensates for power the low threshold uses) and there you go, done! Tested on my galaxy s2 first then sidekick 4g, methods work for both devices.

I only ever see a battery issue when I use wifi. But I might as well try this out.
