Hello,
just installed CPU-Z from the app store which shows a constant 30-40% CPU usage. killed all tasks with task manager, but still doesn't change.
Is this normal or anyone else experiencing it?
Running Stock HTC Android 4.0.4
Cheers
Mine is running at about 10-30 %.
One S (S4), Stock rom 4.1.1 (Lastest)
Do you have any problems with your phone?
Something to think about: your CPU will adjust its frequency depending on the load for energy management. For example: if your doing nothing you could be running at single-core 128MHz. So maybe it shows 30%, but it could very well be 30% of 128MHz(in short).
So those percentages do not necessary mean your phone has a problem.
My battery life is aweful. I can get around 2-2,5 hours of screen on time during a day...battery seems okay though. might have to do a factory reset or flash some custom rom.

Meaning, does the battery life take a dip when you overclock to 1.5ghz. Does it get any hotter? Is heat an issue at all on this thing? Also, any performance or battery changes from installing the tiamet kernel itself? I'm in the wifi xoom btw.
Strangely enough battery life seems to be about the same. Heat has not been an issue mainly due to having the dual core, however its something you always want to keep an eye on.
Battery life is affected most by the screen. Screen> Network connections > CPU > RAM
There was a thread that someone made a while back about the things that affected battery life the most. If I can find It ill send it your way. After seeing the charts I figured Id try changing some settings.
things I did:
1. Set my max cpu freq to 1.19 min to 488 same for all my cpu tunner profiles ( I wanted to have my phone running the same all the time)
2. Lower'd my screen settings. I didnt need a pocket flashlight EVERYTIME I unlocked my phone.
3. Turned off un needed network connections. Its not hard to turn them back on when you need them.
4. I then looked for things that were running but were not needed by anything ( google maps are used by a few apps so dont disable it haha) I used Uninstaller for root users to get rid of some things.
After all these steps my battery life went WAY up. I have been doing the same thing on my Xoom now and my batt lasts the same at 1.5 as it did at 1.
I still get VERY respectable battery life at 1.5ghz, I can easily get through the day with normal usage. Yesterday night in fact, I left the house with maybe 75% battery life, used my tablet quite a lot throughout the evening(left the house around 9, went to sleep around 1am) and used it all morning basically constantly from 7am to around noon and came home with 9% battery left.
No problems here either. Woke up around 8:30 yesterday and used it all day sometimes pretty heavy. Finally had to plug it in around 6:30. I'm home all day with a broken hip and femur, so I've been putting it through the paces. Running @ 1.5ghz with interactive gov.

+1 on 1.5GHz having little effect on battery life. I didn't have to change anything else, either.
thats all great to hear! I suppose ill start looking into rooting my wifi xoom tomorrow then. Thanks for the help!
Im very happy with the battery life on this thing. I expected 4 hours max after a few weeks of use/charges. I never thought that it would keep up with anything Apple, Lets face it.. Apple knows how to make stuff run forever. But I was plesently suprised. Xoom +1000
yeah, the battery is good, but i won't know any damage to the cpu when overclocked ?
I wouldn't worry about any CPU damage- too many people have reported success (and no reports of failure).
Anyone else notice with the tiamat kernel that their xoom becomes very unstable overclocked at 1.5 using setCPU? Mine was essentially a soft brick at 1.5 constant rebooting and never able get pass the unlock screen, I had to rewipe with bootloader. I can do 1.2 no problem but don't even want to try going higher.
All of our chips have variations, so the overclock isn't universally guaranteed. That being said, I've been using the Tiamat kernel @1.5GHz since it was released with no problems.
Should have stated that mine is the wifi model, but yea thanks for info.
Here was that post I was looking for on this stuff. http://forum.xda-developers.com/forumdisplay.php?f=946
So I have the HTC sensation and have noticed that my battery doesnt last as long as it has done previously, i've gone into settings > about phone > battery information and can see that my usage is being raped by the Display which is currently at 70%! I have nothing else taking up the usage.
How can I reduce this? I've followed the instructions of turning down the brightness, turning off background sync, bluetooth, wifi, 3G etc and I always use the task manager to kill off tasks that i've used previously in the day that I dont need sitting there anymore.
I recently flashed to the Android Revolution HD ROM with beats audio, is there anything I can do regarding the ROM? I didn't wipe my phone completely before installing the ROM so i'm thinking to try that... also now the CPU is 1.5ghz as it's an XE ROM, how can I reduce the CPU back to the standard 1.2ghz the sensation originally comes with?
I appreciate any feedback guys!
Before installing a rom do the factory reset ... As for the processor just like you install SetCPU and put the maximum frequency you want

So will doing a factory reset AND THEN installing the ROM stop my display from being constantly 70%? it seems to stay at this level and doesn't drop at all. Since installing the ROM i've noticed the battery dropping faster than it did before, i'll use SetCPU to change it back to it's original 1.2ghz
Thanks for the reply!
The display on my HTC Sensation sometimes even consumes more battery, but I think it's normal since it is a 4,3inch-LCD-display and it surely uses more bettery than a AMOLED or a smaller display. But that's a problem for most of the smartphones.
May sound silly but try Go Power Master.
I use it on a Nexus S and I can eek out about 36 hours of use on one charge.
Hey XDA,
I'm running PixelRom 1.7.2 and Trinity TEUV and my phone is almost always running at 1000Mhz, which is causing terrible battery life. Even if I'm just idling at my launcher, it will go that high... Anybody know how to get it to stay at lower frequencies? Oh and my governor is Ondemand and scheduler is Deadline. Hope someone can help...

teuv runs at 880mhz.
its possible that an app or a background process is active. try this free app from the market, its called diagnosis https://play.google.com/store/apps/details?id=eu.thedarken.diagnosis&hl=en
I thought it did too, but NsTools and CPU spy both give me: 100Mhz, 200Mhz, 400Mhz, 800Mhz, 1000Mhz, and 1096Mhz. I will try the tool from the market (yes, I still calls it the market)

1096... thats not teuv, that the t11 kernel. heres the latest teuv http://goo.gl/5JwMT im using this one at the moment
My thanks good man, that was the one I was looking for, now I feel quite silly :3
Right now, just at my launcher, cpu is switching from 92% to 100% usage :s

if you just booted, it should(for about 2-4 minutes) then it should drop. unless you have an active live wallpaper, an app thats not written very well, or a process thats gone wild. try that app i linked, let it run for a few hours, maybe you can find the cause.
My phone had been on for a few hours...
Also, I flashed TEUV, and I don't think my phone handles it very well (TEUV has GPU overclock). Once I booted, it gave me a black screen and said: (Application) has stopped working for every app on startup. This happened twice, so I went back to Matr1x and battery is still terrible...

sounds like a bad download of teuv.
Bad download? I flashed it properly and it booted fine, until after the "optimizing applications" screen
is this the first charge since you flash the kernel? If it is, let the battery run out, charge it full and take a look at it again. I find that ICS really take a full charge to stablize its battery... my first charge after flashing a new kernel has always use a lot more battery than the second charge.
Alright, I'll try that... Also I went back to aosp+ because I really like it.
Also, android system is always using 20% cpu, even on idle..
I remember performing some tests with frequencies and deep idle - I wanted to find out the minimum frequency required to run music player screen-off with few concurrent processes. I remember reading how 400mhz is the optimal frequency for deep idle but cpu spy would always report it cruising at 1ghz and cross referenced with nstools DI stats, it was supposedly in deep idle. With DI off and bumping up the frequency to 800mhz, 1ghz took up the majority of operation time. Long story short, whatever combination I tested did not garner desirable results. That was a couple weeks ago, though. I've since given up on figuring it out.
Wait, are you having the same problem as me?Ive lost 5% battry just by having the screen on for 9 minutes...
After reading a lot of battery drain threads on this Samsung Galaxy I9003 subforum i have a doubt:
The recommended solution is to install a clean android 2.3.4 rom?
In my case the phone came with froyo and after a couple of months i decide to upgrade up to 2.3.5... anyway, about one week the phone starts to constantly heat up on stand by mode without 3g or wifi activated and off course the battery starts to drain :S on battery stats i can see the bigger consume (about 62%) is related to stand by mode :S
I try :
battery calibration
factory reset
wipe
reflash 2.3.5
flash 2.3.6
But sadly the problem persist :S
Todayi installed CPU spy and i got a big surprise when i saw the stats of CPU speed, most of the time turns to 1000mhz , like i said the phone it's ond stand by mode with no 3g, wifi connections activated :S
Also i rooted the phone and installed setCPU to limit the max speed up to 300mhz, with that i can see the phone doesnt heat that much (compared when it runs at constantly 1000mhz) but still works at constant 300mhz whatever i do...
I really hope that the solution is to reflash 2.3.4 (or maybe lower?) firmware
Thanks for share all your knowledge and help people like me
If that the case then its an APP. You surely have an app that avoids your phone to go to sleep.
Thanks for your attention and time, i hav running setCPU (at barely 300mhz) and now the CPU temp is always at 32°C also i installed Watchdog lite and doesnt show any program doing an excesive CPU usage :S
Really i have no more ideas of what to look at
Yesterday at night i was reading a lot of drain battery related post (all the threads i found basically) and do the following:
Enter to CWM recovery menu > Advanced > Wipe dalvik
Also i select the ondemand settings for setCPU
Now the phone it's all the time on stable 36°C but sadly my battery still is drained (probably on deep sleep) Most of the time the processor is only at 300mhz and looking the battery stats android system and screen use an average precent (42% for display 23% for android system)
From a full charge (over a powered off phone) after 4 hours the battery has only 40% of ramaining charge and the phone it's on deep sleep (this phone today it's used only for make and receive calls, so no internet connection is activated)
No other people are facing this issue?
Starting a month and half ago my LG Nexus 5 would get hot near the camera (Where the CPU is) and drain the battery unusually fast, even without an active app opened, now I can not keep it on outside because of the drain and even if it stays connected to a charger, it slowly builds a charge because of the drain.
I recently changed the battery and the problem continues to persist.
This started happening around when I went over all the settings in the phone and apps, I fear I might of turned on something that is causing it in the background but I can not figure out the exact problem.
Please help.

Check the frequencies of the cpu, sometimes the minimum value gets stuck to a higher than needed frequency.
You can do so by using Kernel Auditor (root) or CPU-Z. Obviously if they're higher you'll need to set them lower, 300 MHz is the normal minimum freq. If that is not the case then install Gsam Battery Monitor and enable extra stats, you should be able to figure something out with that one app.
