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 , my device is moto g (2nd Gen)
When I play Clash Of Clans app , the screen of the device is over heating
Please suggest rectification for this issue
Dont play for too long..If you really want reduce the brightness use Wifi instead of Mobile Data..If you are ready to risk root it install set cpu reduce the Frequency to 1 Ghz use some other Governer except performance like interactive or on demand

hey see the mob is under great stress when you try to play games for long duration which leads to the overheating issue that you are facing, i might advice you to first of all clear ram before playing and also don't play for too long because that drains the battery pretty fast and that might harm the long term battery performance
The device has built in thermal throttling. And it really doesn't get hot, I've owned higher end phones that get hotter. I actually tweaked the thermal file so it throttles less until more serious levels. My advice? Don't worry about it, and don't game while charging because that makes it heat up fast causing lag due to the device protecting itself. Happy gaming
Is anyone seeing very fast battery drain? Currently running skydragons Dev edition ROM and kernel. Tried using greenify and juice defender to help mitigate it but not having very good results yet. Any suggestions?
Battery fine all stock.

Stock Battery Drain
I'm running Stock and i am having very bad battery drain. I installed CPU Spy and noticed that the CPU state "Deep Sleep" is never used. CPU is normally at 960 MHz and 384 MHz. I also installed GSam Battery Monitor and after a full day the Kernel and Android System 40% of the battery drain....
Is anyone else experiencing the same issue?
Give it a few days, let it break in
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
Hello, I am using a z1 C6902 on lollipop 5.1.1. My free ram is about 350 - 500 mb. However i got intensive lag when unlocking the phone or turning on data or wifi or switching between apps . Using showing the cpu stats in developer options, the phones shows that i have the very long blue area. Usually system_server and kdswap0 is the culprit. I tried disabling swap but still has big i/o wait. Does anyone have the same problem?
