I noticed... have any kernel or rom and device had problem with game ( Pubg, Battle Bay)
I have turboZ kernel, for example and RR rom 5.8.5
i set cpu to 300mhz - 2,2ghz
when I start the game few minutes, the cpu has 1.2 ghz
when I turn off the cpu game it will return back to 300 - 2.2 ghz
I turned off the thermal protection and doze battery effect
still does not help
Where is problem please ?
It's probably just multiplayer lag. Try checking the ping,
and make sure you choose the closest server whenever you have a choice.

I am starting to believe that the ICS kernel scales properly although some people may claim it only scales from min to max.
I noticed on the stock GB kernel, the exact same thing happens when trying to use CPU controlling apps such as setcpu. However, for BOTH GB and ICS without using CPU controlling app, I can see the in between frequencies being used. When I try adjusting the slider THEN it starts the freaking out in terms of min/max. (Rom toolbox)
I even notice the battery life worsen tremendously when trying to use setcpu, antutu, etc on STOCK frequencies. Perhaps it has to do with people trying to use CPU apps on a kernel with the perflock enabled?
With the absence of a CPU controlling app on ICS , my battery can last the SAME (not worse, for sure) as it on GB.
Perhaps this can help those who complain about bad battery life on ICS

You don't need to wonder anymore! Its a function built into HTC kernels called "perflock" and its function is to continually reset the values for the min and max frequencies in order to prevent other applications such as setCPU from taking control over the CPU frequencies.
I've been using SEbastianFM's ICS OC kernel with setCPU. You are correct, that it does scale properly even though the min/max frequencies hop around. If you take notice of the current frequency, its usually appropriate for the current load level.
Furthermore, if use setCPU profiles to control the CPU speed, I've noticed it prevents the kernel from periodically reverting back to its default speed and governor settings. setCPU occasionally crashes (FC's) about once a day on me, but since I have the widget on my homescreen I notice it starts right back up again within a second or two and starts controlling the CPU speed again.
Hi, all!
Some people, like me, may have downloaded a cpu-monitor app like System Tuner then notice their second cpu (cpu1) always appears offline.
First off, I recently realized that that is often inacurate. Using another app like SystemPanel would show both cpus being online, and more importantly, checking sys/devices/system/cpu/cpu1/online would show it's "1" indicating online. Many cpu app's inability to read cpu1's info is because "cpufreq" folder is missing from cpu1 folder (if you check cpu0's cpufreq folder it's always there).
K, now also, some poeple like me, thought cpu1 was really offline, and used System Tuner's "Force all cpus online" option, and viola, after reboot the second cpu showed up. But why? Cuz a "cpufreq" folder is found in cpu1 again.
What is interesting is both files "affected_cpus" and "related_cpus" would show "0 1" meaning core 0 and core 1 are in sync and both coordinated simultaneously. if you change settings(freq,governor,etc) for one core it automatically changes the other.
Now here's the tricky part, however after the tablet goes to sleep, when I wake it, cpu1's "cpufreq" folder would disappear again, meaning Sytem Tuner would show cpu1 agains as "offline". But if you chekc "online" file in folder you'll see it's still online ("1") and SystemPanes still shows cpu1 activity. However "affected_cpus" and "realated_cpus" will show only "0" meaning only cpu 0 is in this categoty and cores are no longer in sync.
Conclusion: so far what I deduced is my tablet in its default state has both cores online, but are off-sync. After turning on "Force all cpus online" and rebooting, they are both online and in-sync. After the device goes to sleep and wake, the two cores are still online but now off-sync.
The important thing about this investigation is how much it affects 3D performance. I was always confused why my device lags with a aged-game like Counter Strike portable but is perfectly smooth in a consol-quality game like Mass Effect Infiltrator. My current thought is Mass Effect acttively tweaks your cpu while most other games leave cpus as they are.
Benchmarking (using market benchmark apps):
(First off, the FPS difference may seem small but in running the actual games for some reason it made a enormous difference, often the difference between crashing and not crashing/playable or unplayable in Nova3/Shadowgun)
Default, newly flashed rom: FPS :33 (Some games fail to load graphics properly for some unknown reason)
Turn on "Force all cpus online" with Sys Tuner: FPS 39-40 (All games are silky smooth, no errors, tablet temp hotter)
"Force cpus online", then after wake from sleep: FPS: 33-34 (not as smooth before sleep, but games generally load properly)
**Switching my cpu0 gonernor to the same governor I think cpu1 is using: FPS 35-37 (no errors, almost as smooth as "Force cpus online")
Here's a crappy surprise --Cpu1 off (turn off dual core): FPS: 39. (Completely smooth, zero errors, hottest tablet temp)
**after cpufreq folder disappears from cpu1 I cannot be sure which governor cpu1 is using, but checked with Kernel Tuner and believe the system switch it back to "performance2" which is a governor foudn in my tablet.(it it not like "performance" governor) upthresh 60 downthresh 30 freqstep 5.
Conclusion:
This leads me to the conclusion that having both cpus online does not necessarily improve performance, but if the two cpus are off-sync it definitely BUTCHERS performance. It does so so badly that running one core is actually better. Having both cores run the same governor also seems to help somewhat.
Need help:
I hope the info so far may helped some people, but the help I also really need is someone to tell me how are "affected_cpus" and "related_cpus" controled by the system? So far I had no sccucess modding their values and forcing cpus to "sync". I enter "0 1" but it doesn't go through. Since having the cpus in sync seems to give good performance and lower temp (single core was good but temp was noticeably high), I want my cpu cores to remain in sync, but currently it undoes the sync after waking from sleep. I need to understand how and why the system somtimes decides to coordinate both cpus synchronously so both cpus appear under "affected_cpus" and "related_cpus"?
Thanks to anyone for reading!
Hello everybody, today I present my guide or actually the procedure of modifications presently installed on my Xperia U.
1. Grab your Xperia U (I presume it is bootloader unlocked, rooted and installed Stock ICS based firmware)
2. Battery Supercharging-
a. Let your battery charge to 100%
b. Unplug charger and Reboot into CWM and wipe battery stats
c. Reboot into system and use phone as normal until battery is exhausted. (Now your battery is calibrated)
d. For maintenance of life of battery pack thereafter, let battery drain to not below 10%
e. Always charge battery short of 100% i.e. 85-95%
f. Once in a month, shut down your phone at 30-60% charge, remove your battery, and just leave it outside the phone for an hour or so.
Be compassionate, as Gandhiji had said
g. If you want to recalibrate your battery, follow steps 2a-2c. Recalibration for Li-poly is not that essential, since it has no memory but you can do it once a month or after flashing a new ROM.
h. Never leave your battery discharged for very long. Your Li-Poly battery will suffer a deep discharge.
3. CPU Control
a. Download BrainsKernel or Munjeni's Kernel
b. Install it using flashtool or fastboot (i presume you know how to do so)
c. Download your favourite CPU Control App (setCPU, noFrills CPU Control etc.)
I recommend CPU Tweaks as it gives you info on both cores at the same time and also has the time graph for when CPU is asleep (setCPU lacks that)
d. My recommended governor setup-
[Try to use a governor with inbuilt hotplug technology (hotplug means ability to control cores i.e. turn of second core when not required and turn it on when required) Eg. Hotplug, Lulzactive, PegasusQ, Hotplug etc.]
For normal use-
LulzactiveQ 800/200 MHz
For Music(Screen Off)
OndemandAX 800/200 MHz
For Gaming(Dead Trigger etc.)
Ondemand/Hotplug 1000/200 MHz
TIPS-
Remember that most governors with a screen off profile(Smartass, LulzactiveQ, OndemandAX) built in have a wake frequency (CPU immediately jumps to that frequency when screen on) is around 500-700 MHz, so try too keep your Max CPU limit at 800 MHz to prevent screen on delay. This is required as Xperia U has no 600 MHz intermediate CPU step, it has only 400 and 800. 400 is below the wake frequency so capping CPU at 400 MHz will cause lag during wakeup.
For me, using LulzactiveQ saves more power than SmartassV2 or Powersave. This is due to the fact that LulzactiveQ shuts off my second core much faster and much more dynamically than SmartassV2 of Powersave.
LulzactiveQ has a screen off profile of setting CPU speed to around 200-400 MHz while OndemandAX caps it at 500 MHz.
So OndemandAX is better for music as there is no tearing in playback when screen is turned off.
e. If you want to forcibly keep one core off (NOT RECOMMENDED. USE A HOTPLUGGING GOVERNOR INSTEAD) use XCore. It works on Xperia U and Xperia P. Check out the Play Store for further details.
4. RAM Management (Android does this on its own, usually. But you can help it)
a. NEVER use a Task Killer. Android kills tasks much more dynamically than your brain does
b. Delete all bloatware you do not need. This will prevent some background processes from being run and it will save some RAM.
c. Do not use a separate app for Facebook unless absolutely needed. (XDA App is fine )
d. That widget, sitting on your homescreen, which hasn't been touched for the past 1 week can be trashed.
5. GPS Superiority (You'll never use AGPS anymore)
a. Download an app called FasterGPS from the Play Store.(needs root)
b. Open the app and choose you continent and region. If your region isn't there, choose the closest region.
c. Get your ass out in the open and get a lock in less than a minute only on pure integrated GPS.
6. General Tweaks
a. Go to developer options in settings and set Animation Scale to 0.5x
b. Get a good statusbar mod (I recommend Xperia Tab n Grid Jelly Bean).
Why? So that you turn off the WiFi and BT and Packet Data when not required. I wouldn't do that earlier as I was too lazy to go all the way to settings to do so. Now I use the notification toggles and save some power
c. Turn OFF your phone and then charge it.
d. Use Lux Dash, an app to control your brightness. At night, set it to sub-zero to save power.
7. Physical Tips
a. Get a case for your phone. Incase you drop it, it will protect your phone.
b. I know you're tempted to take your phone to the pot and have fun but NO. People have lost phones like that.
c. Every week, clean your phone with a spectacle cloth.
d. Do not overstress your phone, or else you risk your hardware. I know they are designed to face all this but as Gandhiji said, compassion.
Hope these tips help you and your phone
Im using cpu controller but after a few minutes I set cpu, it turns back to original setting. I tried synapse kernelauditor and setcpu. all are same. KTweaker was perfect but not working for 5.1.1 now.
is it about kernel (tried simpl and uni) or any app?
Hello! I have an a32 5g and when I run intensive apps like emulators such as dolphin mmj and aethersx2, I can clearly see a drastic increase in performance when my finger are on the touchscreen. How can I ensure that my phone is running this fast all the time?
It's caused by "input booster", likely forcing CPU Freq at max_freq.
Try to tune CPU governor, e.g. set lower value for up_threshold.
Or you can use performance governor, but this will use max_freq all the time, draining battery very fast, except in deep sleep state of course.
I found Franco Kernel Manager and already have per app profiles set up to change when aether or dolphin launches. Thanks again!
*Completely fixed the problem btw!
