CPU usage - Nexus 5 Q&A, Help & Troubleshooting

Does anyone tell me why my phone runs at the highest frequency?
Even with all apps closed and even after restarting it. Also the WiFi consumes battery when its turned off.

[Q] Anyone use CPU Spy on their Skyrocket

Has anyone else been using CPU Spy to monitor Deep Sleep? I haven't once seen my phone going in to Deep Sleep. Anyone else?
Yeah I used it since yesterday. I've frozen a ton of bloatware via TB and it went into deep sleep for 7.5hrs last night while I was asleep. I'm seeing a crazy amount of different CPU speeds in there too though. Very odd.
I actually removed all the damn bloatware instead of freezing them. But then I added my own apps that I normally use. But I think I have finally weed out the damn app that is causing my deep sleep issues. it's either FriendCaster Pro or Google Music Beta...
I gave it a try yesterday when I first picked it up. Seems to either idle really high, or low depending on what your doing. Hardly ever used the mid range cpu frequencies.
yes! Once the source code can be.... had.... Kernel development would begin. As anyone have seen using CPU Spy, the governor either MAX out the CPU or just lower it to the minimal, it "rarely" stays in the middle. With some "tweeking" how the CPUFreq works we can probably save battery

I have been using it for a couple of weeks now along with Antutu CPU Master. After charging, I usually reboot my phone and deep sleep kicks in. I use Antutu to lower the CPU speed to 192 mhz.

Are you having any problems with Antutu keeping the setting at 192, after I reboot my phone Antutu keeps changing the low setting up to 384? Yes I have it set to apply on boot. I sent the Antutu devs an email a few days ago asking them about this, but no reply?

I thought this was the deep sleep issue that people have with certain chargers?? plug charger in and let screen turn off then turn screen on and unlock, then unplug charger. Check to see if it goes into deep sleep then or just reboot the phone after charging....

Hot cpu

I noticed when browsing the web that the phone quickly gets quite warm so I installed StabilityTest and TempMonitor from Play store and ran a Classic Stability Test, within 2 minutes the temp went to 55°c and after 10 min is was 59°c, anyone else having these high temps? Running on battery...

Just gave it a try, struggled to get over 30c..

Ok, thanks, was that battery temp or cpu temp?

Sorry that was battery. After 15 mins, CPU was up to 55c, didn't go any higher.

I have the same issue with my HTC one S, while i'm using browser (internet, google chrome) or download something with network mode "Gsm/WCDMA auto" my phone constantly changes between HSPA and 3G connection and heating up to 45,5 C. At this time, the battery consumes 1% of every minute. This is a problem of firmware of radio module or something else?
Thank you.
is anybody else concerned with how hot it gets? It takes just a few minutes of browsing and playing around with apps to bring the temp from 26-28C idle to 35-40C when the entire backside gets really uncomfortably warm. did somebody have a chance to play with different units to compare if they all do this?
Yeah it gets pretty hot, but I don't think it's too much to be concerned about. I think it's just an effect of making the phone so thin and making the body out of metal that means it heats up pretty quickly. As long as it's not going over 60 degrees I wouldn't worry! And if it does, you probably won't be able to hold your phone anyway

Heat, max speed processor = battery drain ?

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?

[Q] Battery life for a wifi only setup

Running the latest version of GimmeABreak, stock kernel. Using it as just a home use wifi phone, so mobile data is turned off. However for some reason cell standby is using a large portion of my battery.
Is there anything I can do to get about better life out of my inspire? I ran through both the battery saving threads in the guides sticky but it doesn't seem to be a rogue app causing the drain.
using SmartassV2 gov at 245 min 1200 max.
*Edit - To clarify (as I wrote this post late and under the influence of several Tylenol pm) I really just want to know if there is a way to disable cell standby as I don't need a cell signal for a wifi only phone. Thanks in advance for any help anyone can provide

LG Nexus 5 - Overheating, Battery drain.

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.
