Long time lurker, but 1st time poster.
I've noticed on my Revolution that the CPU always runs at 1ghz. I thought CPU throttling was a standard feature in android?
Anyhow I installed CPU tuner and I get much better standby battery life now (~2% drain/hr when not using phone vs. ~5% drain/hr on standby). The phone runs mostly at 124mhz w the screen off. My problem is my revolution reboots pretty frequently and sometimes even just completely shuts down w CPU tuner on. I still get reboots once in awhile w CPU tuner turned off, but much less frequently.
Anyone else having this problem? I also have green power running in the background to turn off the data connection w the screen off. Are you guys who use setCPU not getting reboots? If so I'll spend the $2 and give that a try.

I honestly don't think anyone has been messing with the CPU until the CM ROM is released.

As far as I've seen, the Revo's CPU does automatically speed scale to the necessary load.
If you're running lots of apps in the background, with the screen on Android will keep the cpu at full throttle to provide a smooth experience for you.
As soon as you turn off the screen, it will throttle it down as much as it can.
If the phone's rebooting on you, that's because whatever cpu tuner is doing may be keeping the cpu speed too low for the demand of the OS, then the watchdog kicks in when it thinks the cpu is stuck in a loop. (watchdog wants to be petted every 30 seconds, if the cpu misses that, the watchdog reboots the phone)
I use setcpu and have no reboot issues.

throttle
I use android system info to show the CPU speed. It shows the % of time my revolution is running at each speed. W/o using a 3rd party app it always shows 100% at 1Ghz. W CPU tuner running it shows 50% at 122Mhz, 25% at 1Ghz, and 25% in between.
I don't think I'm running any apps thats sucking up a lot of CPU. I'm rooted w most of bloat removed.
Am I the only one not seeing any CPU throttle on stock?
i'm not seeing any throttling on stock.
setcpu drastically improved battery life when the phone's off, and no reboot issues.
some issues initially with the phone not throttling back up quickly enough when i got a call, making me unable to answer the call, but played with the settings and made it so it automatically throttles back up to 1024 when i get a call, and now it's fine.
Exactly Im much happier with my phone now. I had the same issue when I received a call but set up the profile as u did and have no problems at all

I am using setCPU as well with no issues. I have mine set were the screen is off it goes to 124 and clocks back up to full 1GHz when it is on. Helps greatly improve my battery.
So what settings do you use? I get really bad lag when waking my Revo. Sometimes it will reboot after waking too.

I don't know if this is a CPU throttling issue, or a general REVO issue, but I get horrible horrible lag sometimes trying to get any programs to respond. Like press the home key, or click send, or anything like that. I'm running Decrap 1.1, I don't know if I have too many processes running or what.
Interesting. The Thunderbolt has the same issue. Is it the same CPU in that phone?
Hi all,
I've recently installed Rocket ROM v13 along with AbbyssNote 2.6, but I'm experiencing frequent phone freezes and a abnormal warm device.
I've tried setting the voltages back to standard values, but that hasn't fixed the problem.
The freezing happens the most when launching the browser and less frequently when playing games.
Is there a way to test what frequencies work with what ideal voltages? And getting rid of the heat would be nice too Thanks in advance
The heat is probably mostly from the Wifi problem. You may also have trouble with CPU being overactive.
Leave the voltage alone as it will cause stability problems. Its just a bandaid and not the real solution to your heat issue.
What is the room temp and battery temp of your phone?
Sent from my GT-N7000 using xda premium
My battery ranges from 40-50C when on idle use. The room is around 20C.
The phone gets really hot on the top 20% whenever I use it for a decent amount of time.
I currently have the phone on default settings. From 200-1400 Mhz and the voltages found here.
This heat is something i am battling with also, tried many things even reducing volts does not seem to help.. i think it's just the way it behaves.
My Note can be laggy in random situation and I am trying to figure out the cause of it. Some of the RANDOM lagginess happened in the following situation:
1). Turn ON from sleep mode --> open built in Browser --> hit "Back" button to quit Browser, Note lag for about 2-3 seconds before the operation is completed.
2). From Home Screen --> click on "Application" to bring TouchWiz app list --> click on a "Folder" --> Note lag for 2-3 seconds before opening the folder
3). Open an application (ANY application) --> click "Back" to go to the previous app screen --> Note lag for 2-3 seconds before the operation is completed.
So you see, in some cases, the Note is really fast and in other case, really laggy.
I use WatchDog to monitor CPU usage to alert me when ANY processes (system or user-apps) is using more than 40% CPU. Watchdog alert me that these 2 CPU is using MORE than 40% of CPU every 5 seconds, especially when the device is on sleep.
- suspend --> average 48% cpu time
- events/0 --> average 46% cpu time
NOTE: The average above was done over the span of 4 hours
What is "events/0"? More over, why would these 2 processes use almost 50% of my CPU time every 5 seconds?
If the above process using 50% of CPU is "NORMAL", what would cause the lagginess? Do you guys experience these also?
2-3 seconds seems extensive. I have never used Watchdog - perhaps it is causing the lagginess if it is checking processes aggressively.
Could be ROM/Kernel combination also as well as governor settings. Perhaps change your governor to performance and see if that gets rid of the problem (will drain your battery quicker) or ondemand. If problem persists try a different ROM/Kernel combination - some are laggier than others depending on your phone.

Watchdog is a CPU monitoring process application and the reason I installed it is because the lag issue before I install Watchdog.
I use stock ROM, so I don't have governor app in it.
Very unusual for stock ROM to be that laggy. What other applications have you installed recently? Would try to uninstall them and see if lagginess disappears.

@lanwarrior:
Whatever is happening is a direct result of something that you have done/installed/setup..
I have stock rom/root and my results are that in test cases #1 & #3 above where you see 2-3 secs, i see ~0.1-0.2secs
I assume you are setting up constant test conditions, ie
task manager>active>close active apps
task manager>ram>clear memory
settings>apps>running services>stopping all non critical services

I do use ZDBox, an app that close active apps when the screen is off.
I haven't install anything that results in significant system changes. As a matter of fact, I create a list of apps that run in the background so I know what they are.
It seems that many of you don't have that problem, so I'll go back and start uninstalling unnecessary apps and see what happen.
Updated section:
After clearing cache through recovery and doing a hard reset, the uAh has gone back to 3142000. Standby time seems good with the battery losing 7% overnight. It does charge quite quickly from 0-100 in about 2h. The previous heating issue remains with cpu monitors showing that the cpu jumps to high clock when I touch the screen. I don't see any change in which apps use the most battery with the screen taking up the most as before the problem started.
The heat appears to be what is draining the battery but I can't find any single app that causes it to ramp to max.
Pictures:
No-frills is set to stock settings to see how the phone handles the actions
2nd picture is when phone is idle
3rd picture is immediately after swiping through a few tabs and scrolling through some pages in the app which causes cpu clock and load to increase
Old sectionFor when battery uAh was low)
I've had this Z1 for about 11 months. I can only get around 2.5h on screen time with regular usage. The battery uAh was only 1848000 Recently it fell to the 1700s. Calibration appears to reduce the value further. The phone seems to heat up in about a minute or two no matter what app is running.
The phone is rooted on stock 4.4.2
I have tried updating to Lollipop before but received an error due to rooting, so I don't think anything changed.

sounds like it's time for you to replace your battery.
You may try to disable the "input boost frequency"
By default when you toch the screen, cpu frequency of two cores instantly jumps to around 1400 to preventing any lag but it seems to use more power and causing heat
I have disables this and since then I'm no longer have any heat issue and also the battery life is so much better now but you may exprience a little lag while scrolling on heavy web pages but thats all
Btw i'm on .157 and using Kernel Adiutor for cpu tweaks
You may disable this by the app mentioned above or by editing sys.somc.touch_perf_kick=1 from 1 to 0 in buid.prop or adding this line
Anything is valid. Preferentially without root.

What is your current battery performance? Is your device affected with the fingerprint sensor bug that locks the CPU at highest frequency?

About 6-8 hours in moderate-high use, I guess. I don't think it is, how can i know?

Install a hardware monitor app like CPU-z or DevCheck. If you CPU frequency is not coming down from the highest value (for 4 small cores: 1843 MHz and for 4 big cores: 2208 MHz), you are most probably affected by the bug. You can disable fingerprint sensor to conserve battery in that case.

If you are talking about SOT, it's quite normal.
You can't really improve SOT.
It depends mainly on two things : Brightness and Kernel settings. Kernel you cant tamper with without rooting/unlockin your phone, so the best improvement can be achieved via auto brighness.
If you are losing too much battery while phone is idle/screen locked, here are some steps you can follow:
Limit background use of an application from Settings/Battery (Even google play services, notifications still come through)
Disable background data use of apps from Data Usage (Especially facebook/messenger ones, notifications still come through via GCM - use to your own likings though)
Clear Google Play Services cache, as it somehows causes battery drain
Disable location and google location tracking
Disable "Data always on" at developer settings. No point of keeping an active connection while on WiFi
Change network to 3G Only, if your 4G coverage sucks, so it drains all your battery

When i quit the app and come back, the frequencys are at the maximum value for a milisecond then goes to 1401MHz(CPU 0-3) and 1113MHz(CPU 4-7). So, I don't think I have that bug. What do you say?

Auto brightness? Really? I thought that was a battery killer. My brightness is in about 25% most of the time, so, I don't think that is the bigger problem, do you?
Well, thanks both of you guys for the help, and I will follow your instructions(but not the auto brightness one, I don't really like it), Reptant. I will try to remember and report the results at the end of the day.

Yes, that's right. Disable auto brightness, and keep the brightness at around 10%. It is more than sufficient in indoor conditions. Further, disable high accuracy location settings and set it to battery saving or off. You should also turn off WiFi and Bluetooth scanning in location settings.
I personally use a rather far reaching way of force stopping every social media and other news apps after using them (I have never observed any 'misbehavior' as they warn, but it saves a great deal of battery life.). As you can see in the screenshot the battery has lost 7% of charge in 2 hours and it still expects to last for 1 full day.

The suggestions from Reptant above are still valid.
Other than that:
1. Greenify. Set non system apps to shallow hibernation. Try Amplify if you dare.
2. Disable ads. The image/video ads may not occupy a lot of your screen, but they use much more data than text. disabling those ads will reduce the amount of data that the modem needs to download, hence reduce battery consumption. this will have big impact if you surf the web a lot using phone.
3. Change CPU governor to powersave and/or disable some CPUs, reduce GPU max clock speed (you may not like this since it will make the phone laggy)
