Hello guys,
I recently installed an app from the market called Temp+CPUV2. All the app does is it displays CPU Clock speed, CPU Utilization %, CPU Temperature, and Free RAM on a tile as a Widget.
lately, I have been observing fluctuations in the clock which ranges from 100MHz to 1GHz. I thought the widget was faulty. Then later on, I began observing constantly time to time and I found out that the phone really operates on different frequency at different times. Apart from changing the clock speed, I think the self-assessing algorithm eats too much RAM figuring out next clock speed and slows down the phone.
I assume that this features is implemented to save battery, but at the same time, this feature kills the phone by slowing it down so badly that I sometimes feel like smashing the phone against a wall or something.
I use a rooted JM1 with SU and no other mods.
Is there any way to stop the phone from assessing the clock and change it from time to time? I think that's the real reason why the phone lags in he first place.
Nope, thats just the way it works. Install a overclocking kernel and SetCPU if you want to control the clock speed but I advise you just uninstall that widget and not bother worrying about it as you are getting worked up over nothing. SetCPU and a kernel is more trouble then its worth and is very unstable
That's a powersave mechanic.
Save your battery.
It also try to keep your phone cold.
In fact it work well.
It same in computers.

I doubt the lag you are getting has anything to do with this. Look for the lag fixes like Voodoo, Z4mod, or OCLF.
I use z4mod myself, flawless performance
Hey everyone,
I seem to be having an issue with the battery temperature sensor. It will always say 30 Celsius even if I can feel the heat of the battery through the case. Is this a known issue with the tabs? Using sensor test, I can see that a temperature sensor works and is constantly updating, showing temps from 30C to 40C. I'm running stock rooted EC02 with KhasMek Voodoo Plus OC 1.4Ghz.
Thanks for your help.

There are 2 main reasons for a constant temperature:
1- A third-party battery is used which have its temperature sensor removed, you will usually see 0.1 variations, like 30.0 and 30.1 at all times. or more often 25.0 and 25.1 (not sure why though).
2- the ROM or kernel is broken with regards to providing temperature to battery apps. Battery apps get temperature from Android OS using well documented API, which have not changed since the very beginning of Android. See here for more information about the API: http://developer.android.com/reference/android/os/BatteryManager.html
Unfortunately it seems to affect a few ROMs now-a-days.
EDIT: Are you using a S3 with CM-based or OMNI (AOSP-based) ROMs?
So just inherited my dads OG Droid. Currently rooted and runs Steel Droid (Mod Version 9000) and 2.6.32.9_RZ Kernel.
Phone is overclocked to 1GHz (125/1000 ONDEMAND).
Like the title says, the phone gets about 5 hours and then hit's 5% and keeps asking me to charge. If I charge it overnight and unplug it when it's 100%, it'll hit 90% idling (while I sleep) about 3 hours later.
Running Programs:
DSPManager
Words Free
Facebook
3D Digital Weather Cloc
News & Weather
3G Watchdog
Videos
SoundHound
Pandora
Temp+CPU V2
Now out of all the running apps, Pandora, Soundhound, News & Weather, 3G Watchdog, Temp+CPU, 3D Digital Clock are all widgets. Temp+CPU and 3D Digital clock are the only ones that actually run, the rest are just there in case I want to use them.
These stats today are from using Pandora for about an hour over Wifi.
Any ideas? Phone runs fine most of the time but I have seen the occasional lag where you have to click something 10 times before it opens.
I used to have a pretty big problem with battery life too, but even though I think they are somewhat silly and annoying the Easy Battery Saver app helped me quite a bit.
Wifi and using the speakers are heavy on battery life. Not sure how much difference it will make but try consolidating your widgets and app shortcuts to as few screens as possible.
Also your CPU governor might be set to something that lets the phone hog through anything at the sacrifice of battery. When i set my CPU to Performance my phone runs like a boss, while setting it to battery saver I get a little more lag but more battery, obviously. Not sure how/if your ROM will let you change that but it's something to look into.
I got it set to On Demand which might be the issue. The kernel is a low voltage kernel. How do ultra low voltage kernels run?
I did a battery calibration, downloaded Advanced Task Killer (Battery saver didn't work well, I'd always have an issue with 3G not activating) and got rid of all my widgets. Currently charging it up completely, I'll check it out tomorrow.
So the title is incorrect, it says 5 hours and 5% left. I checked the battery info at 5%. It said 4hr 4x min. About 10 minutes later it shut off so I didn't even get 5 hours to a full charge.
I don't have high expectations but coming from an Alias 2 that had the extended battery (I'd get a week of battery with my use), this is pretty disappointing.
Well I can tell you now, ondemand is NOT good for battery, what that governor does is make it so the CPU will go from MIN to MAX speed slots depending on what the phone needs, AFAIK it doesn't scale with need, it just goes to max. So your phones CPU was running at max most the time which kills battery.
Can't say anything about your ROM, but I use simply stunning 5.6 http://www.droidforums.net/forum/chevyno1/177728-ss-5-6-2-3-7-incl-1-battery-other-goodies.html Which, with his low voltage 1ghz kernel set to the smartass governor, I get anywhere from 8-14 hours of battery life depending on use. Using ultra low voltage kernels depend on your phone, some phones have trouble overclocking to 800mhz mid-voltage (mid-voltage is considered to be the most stable, but use the most battery), others can overclock to 1.25ghz ultra-low voltage, which is very rare. I would say try out all the different voltage kernels and see which one works best with your phone.
Also task killer = MAJOR MAJOR No no! The task killer will kill the apps, and the android OS will restart them, using more CPU time and making the battery actually not last as long, I would recommend learning how to use the supercharger script http://forum.xda-developers.com/showthread.php?t=991276
Can't say much about the majority of programs you have running, but I've found facebook does not like to play nice with the Droid, also, why use the 3D clock when the Droid comes with a built in-clock app? Pandora uses a lot of battery, so running it w/ the ondemand governor is probably what hurt your battery there.
Not many Droid users left out there, but I was and still am an extremely avid Droid user, so if you have any more questions just shoot me a PM and I'll help as much as I can.
Thanks! I got rid of all my widgets and installed Chevy's ultra low voltage 1.1GHz kernel on smartass. I lost 20% battery pretty fast but let's see how long it runs. I've had no force close issues so far. I'm a bit tempted to go to 1.2GHz ulv.
How much does the ROM have to do with battery life? I really love this ROM and it's interface. I thought the battery life really only had to do with kernels.
I also got rid of the clock widget and put a default clock widget. What's the built in Android one? Is that the "Analog Clock"?
Sorry for all these questions, I'm pretty new to Android. Only had this for 2 days (~8-10 recharges...)
Its fine, better to question and learn then to just get mad and over it, and Roms have everything to do with battery, they are just like kernels, some work AMAZING on some phones, while others can destroy battery life.
Like my rom, I found the perfect one for my phone, I get 8- (been thinking about it more) 20 hours of battery life on mine and it has pretty amazing performance too with the occasional hiccup.
And I thought you had the clock app installed for an alarm, not for a widget, my bad. I don't use a clock widget so I wouldn't know.. Also, I've found its not very good to run many widgets on the Droid, as it has limited memory and can only handle so much.
Well I got sick of it and reflashed the entire ROM. CPU governer is set to ONDEMAND 125/1000. Only*widgets I have are a simple clock (like the iPhone lock screen) and power control. Gonna see how it goes. So far so good but I'm saying that because I didn't loose 20% overnight. If I can clear the day, I'm good.
googlelover, what CPU Governer did you find to work the best with your phone?
I have been an Android owner for a while now, with the Droid being my first. Until recently battery life had always been an issue for me. Undervolting has never had an effect over a 20% improvement. And this is only when it's in deep sleep. Otherwise, in very general terms, undervolting can require a higher current aka worse battery life if you use your phone a lot. With undervolting comes the risk of data corruption in your phones memory and SD Card. What really kills your phone is screen on time, wakelocks, CPU overclock, and signal quality.
The last you have no control of. But if you're overclocking 1GHz or higher you have to realize that's almost twice the manufactured clock speed. As far as wakelocks, this is when something keeps your phone from going into a low power state. This can happen because of a rogue app, a buggy ROM, or having too many widgets. I ran into a ROM a while ago on my Fascinate that would stay awake if you had GPS enabled. The best you can do with your display power usage is to keep your brightness down. Hope this explains a few things
have the same issue

I already told you, the smartass governor, and like I said before, ondemand is not a good governor in my opinion. There are way to many factors in battery life to have anyone else be able to truly help you with it, all our phones are different and it really just takes time switching kernels, switching ROMs, etc to find what works with your phone
Sorry googlelover, I forgot you already said that.
So update guys. I've been going a day (so like 18 hours) of use after which it finally hits the 15% warning.
What I did:
Basically I reflashed the ROM and started from scratch. Before reflashing, I wiped the user data/cache/davick cache etc at least twice just to make sure it was really wiped.
I reflashed SteelDroid 9.0 with the default chevyno1 lv 1ghz kernel and gave it a go with just a simple clock widget. Worked well. One by one, I'm starting to install applications until I can figure out what was draining the battery fast. So far, so good. If I can get 18 hours on a 2 year old battery, I'm going to be doing fine with my extended battery.
One thing I did notice was that the phone back by the camera (where CPU is) isn't getting as hot as it used to. Makes me think that the phone was at a high clock speed in sleep. Another issue may have been my CPU temp/speed monitor. It was probably poling the CPU stats every second which made the phone increase the CPU speed because it sensed activity.
Try out the ROM I'm using. I absolutely love it. The interface is phenomenal and it runs very well.

(remove the spaces to see it, I wasn't able to post links normally because I don't have enough overall posts).
There's probably other ROMS that run better like the one googlelover is using, but I can't use the default Android interface anymore after using this.

Don't forget not many roms have the default android interface, many have themes to completely change the look, if your happy where your phone is, great! But if you ever feel like your phone is slowing down again, I'd still recommend looking around and flashing some different roms.
Thanks, I'll keep that in mind. I'm only using this phone for another couple months. I'll be getting the Droid 4 when it comes out. Looks like a really nice phone.
Hello guys!
This is my first time posting here, so if I'm breaking any rules please let me know
Anyway, I'm looking to get a new Android device and I'm think I'm going to get the new Sony Xperia Z. The only problem is that I can't get a real device to test it (for just like 30 minutes). Anyway, I've watched a bunch of reviews and read many articles so I good to go, except for one thing - I want to know how much the phone heats when it's running at 100%.
I've already seen some threads here on XDA, but they are mostly subjective (temperatures are mentioned as warm and hot). I would like to get more objective result. If you own a Xperia Z device, you can help me - it won't take too much of your time
Anyway, here is what I'm proposing as a more objective test:
1) Download and install StabilityTest i System Tuner. You can get them in the Play Store.
2) Close all running apps. Run System Tuner. Open Settings -> Recording preferences -> Items to record and check CPU frequency and CPU temperature.
3) Go to the main menu of the System Tuner app and click icon named "Start" (upper right corner). Now the app is logging the in CPU frequency and temperature. Click on CPU icon and not your current temperature.
4) Leave System Tuner running in the background and open StabilityTest. Click on the first button (Classic Stability test). Leave it running for at least 20 minutes.
5) After at least 20 minutes have passed, you can close StabilityTest and stop recording in the System Tuner. The log will be saved on you SD card in the folder pwm/recordings. Please attach it in you post
Please post your battery percentage before you have started StabilityTest and after you've closed it. Also, please post whether you did the test with you phone on or off the charger.
Thanks!

You don't need all this benchmarks because its common sense really. I have the device, on normal operations e.g. browsing, videos etc.. it doesn't get hot, but a bit warm near the rear camera. But, if you do intensive tasks e.g. playing a game e.g. nova 3 etc.. then it gets a bit more hot, but not so much to burn your hands. This is normal because think about the horse power this phone has in a slim form factor and all the heat that gets generated without any cooling fans. Its normal but its not normal if it goes beyond the range of operations, which in my case, I have not noticed. I had a Motorola Droid the keyboard version, that device got extremely hot and it was really uncomfortable to hold.
As a user, I am very pleased with this smartphone and ofcoz it has drawbacks then again no phone is perfect. Hope this helps what you looking for without benchmarks

Transitioning from a low end HTC Incredible S, I found it very unusual how the phone got warm by just going through the user interface.
then i ran qualcomm trepn profiler and it showed that my 1st cpu core was doing anything between 1ghz and 1.5ghz at any given time.
possibly fixed with a kernel tweak?

It should be common sense, but I've read about Xperia Z on many pages. And some users say that it only gets warm, others say it's hot when gaming and some say that it's running too hot. Maybe some of them do have defective units, so this test would be also great for comparison between units. Can you run the test? You don't even need to run it for 20 minutes, 10 should be enough. Or if you won't/can't do the test, can you at least just check in the System Tuner if Xperia Z has CPU temperature sensor - if it doesn't have one then I can stop searching for people who own it.
P.S. Can somebody say if Xperia Z is running hotter or colder than Samsung Galaxy S2?
Hello all!
When I use my Z3C and doing nothing, I mean... just having the phone in my hand, slide between homescreen pages juste for... you know... when you have this sexy lady in your hand... just for looking
But even if I do almost nothing with it, I feel the back hot and my battery apps tell me that the battery is more than 40 degrees. Just for better results I downloaded the app "CPU temp" or "CPU-Z" and it tells me that the CPU is at 45 degrees.
And when I play games the back is more hot!
I just want to know if it's normal? If your Z3C is hot too. I know if I play it's hot but if 40 degrees just for using it with normal apps (Twitter etc...) it's normal?
Can you make some quick test, download CPU-Z and check the "thermal" tab for example or what you want?
For more simplicity in the thread, if you want and if you can, download the app CPU-Z and post the result of "thermal" tab here (just the first line temp), thanks!
And I even see videos of AnTuTu benchmarks on YouTube and the Z3C is at 47xxx... but my Z3C is always between 43xxx - 44xxx ... I don't know if it's the same problem. What scores have you in AnTuTu?
thank you all!
(My phone is STOCK and completly clean, just hard reset before test temp)
my phone is always on 50+ celsius but i think it's normal. it happen on LG G3 too
After about 15 minutes of gaming, my sensor says 40.0 c., but I also have my CPU downclocked by a lot to extend battery life by huge margins. Stock setting puts the CPU frequency at 2.5ghz, and I have mine downclocked to 1.0ghz since I didn't see direct impact on performance with the games I'm playing (mostly emulators or GPU-dependent games).
tsens_tz_sensor0 is the highest at 40.0 c
msm_therm is the lowest at 32.0 c
At stock settings though, my phone runs at 50.0c on average, and it heats up about as much as my Galaxy Note 3 when they're playing the same games. For awhile, I thought the Z3c just heated up more than other phones, but after playing with both phones at relatively the same time, I realize that's pretty much just in my head.
Oh, forgot to mention. Also running on stock 5.1.1 that's rooted, debloated, xposed with greenify and amplify, and a custom Luxx profile to manage adaptive brightness.
