[Q] CPU running at high clock most of the time - Xperia Z1 Q&A, Help & Troubleshooting

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

[Q] CPU throttling on Revolution

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?

[Q] CPU Governor not functioning properly CM11

I've been running CM11 (feb 14 build) now for about 2 weeks with terrible battery drain during use. The phone gets really hot when i'm just browsing facebook or reading a news app.
I looked at the CPU usage and it seems it's either at max cpu, min cpu or deep sleep. That is strange first of all, it never or rarely uses the frequenceis in between. Then i took a look at the battery graph. When the phone is sleeping, the battery is holding really steady, but as soon as I start using it all hell breaks loose and the graph looks like an olympic downhill slope. The strange thing is that the main battery source is the screen which is odd beause on stock (With better battery life compared to this) Android System was the main battery killer.
I then took a look at BetteryBatteryStats. First thing i noticed: 50-50 deepsleep and awake which is pretty astounding.
The wakelocks are msm_hsic_host and PowerManagerService.Wakelocks. But this is strange because it's still pretty much a clean install.
So my theory is that the CPU governor is not functioning propperly and blasts to max cpu as soon as a wakelock is requested and when the phone is in use it also blasts max cpu. I don't know.. that's just what I think is happening with the data i have.
Any ideas?

Reduced GPU when battery 20% or lower

Hi. Probably not only me having that issue. When battery goes to 20% or lower smarthphone reduces it's GPU power and battery usage. Games became inplayable. I tried to find right settings and fix it but without a result.
I tried to switch off that Battery Optimilization (google-> "How to turn off battery optimization on Huawei devices" (I'm a new user and cannot post links) but with no improvement.
Is there any way to fix it? Must be some fabric setting.

Lag,audio bug, reset

Using simple system monitor, I've figured out that my phone starts turning off big cores most of the time and only uses small cores when it has less than 66% battery, and becomes more agresive at less battery, and also it reduces the voltage to the cores, this Is the main cause of the lag and also audio bug and big consumption apps will reset the phone because of this, some people here say that changing battery fixes this problem, could anyone confirm?

Not removing thermal throttle, but increasing thereshold? (PerfZ bug)

A month ago or so, i had this random period of time where perfZ started to show "-" for temperature ( i assume its gpu temperature because it doesnt match with battery or cpu temp from another app) and my phone was heating up much more in games but so was the performance was way better.
Normally after thermal throttling kicks in and device reaches heat equilibrium, my battery would sit around 38-39C, cpu at 42-43C. But in that time period where it showed "-", my equilibrium was battery sitting at 44C, cpu at 47-48C. Phone was considerably hotter to touch but you could still game on it. And performance was way better, it would fall to 50fps min instead of 40fps, which is very noticable. (Dont have exact numbers maybe a bit better)
Idk how this happened as it randomly happened one day but does anyone know how to make this work? My device isnt rooted. (s10+ exy)
(Small note: Using game plugins at max performance or custom doesnt help, maybe they arent optimised for dead by daylight, because thats the only game i play)
