Change your Governor settings (Smartass or Ondemand are fine)
[Xperia Arc Android Development] Marmalux:
set min cpu frequncy to 245. This happens due to deep sleep mode of phone. Also consider changing governors and schedulers.

My config that work fine

Min cpu freq : 184

Max cpu freq. : 1204

Governor : Smartass V2

schduler : CFQ

P.S. : Until a week ago i was using No frills CPU, but now i have found that if using lupus menu to set up CPU and creating a init.d script, improves somehow overall performance. (must be beacuase i freed ram with one more app (no frills cpu) that became uselles ).
[Xperia Arc Android Development] gu5t3r:
LuPuS menu init.d script sets settings at kernel logo (lupus one), CPU Apps set freq when phone is already booted...

So, when set with LuPuS Menu, you also boot on higher freq...

---------- Post added at 10:48 AM ---------- Previous post was at 10:46 AM ----------

Also, CPU apps change only SDCard scheduler, LuPuS menu changes both internal and SDCard scheduler...
[Xperia Arc Android Development] kaz93:
why s is that when i undervolt the phone, the settings doesnt seem to stick after a reboot, it will revert back to the original value..

this happens with lupus menu script and incredicontrol(already ticked set on boot)

after a reboot i checked the voltage using lupus menu.
[Xperia Arc Android Development] Marmalux:
Why don`t you just make a init.d script just likr gu2t3r said few posts before ?

[Xperia Arc Android Development] gu5t3r:
I'm using 134-1516MHz UnderVolted with voltages few posts above...

Governor: SmartassH3

---------- Post added at 03:53 PM ---------- Previous post was at 03:51 PM ----------

Did you choose to save after changing voltage for each freq?

---------- Post added at 03:55 PM ---------- Previous post was at 03:53 PM ----------

Either you did something wrong or you have other script or app that resets voltages... Search init.d and try removing cpu app's...
[Xperia Arc Android Development] kaz93:
Hmm. using your method a few posts ago doesnt seem to work for me, the same goes for incredicontrol..but setting the volt individually for each freq in lupus menu does the job for me..it sticks after a reboot. thanks
[Xperia Arc Android Development] 8730102:
I used ultimate 3.0.2 rom, lupus 16 kernel after flash anything in CWM then my phone can't boot, stop on bootanimation. To remove the battery, the phone will boot. Help me plz.
[Xperia Arc Android Development] jcgechevarria:
Thank's, i mean that you own a Arc S... So for my Arc, which is the recomended max freq, and undervolt table it's the same for arc and for arc S ??
[Xperia Arc Android Development] gu5t3r:
Voltages and Max Freq are not the same for LT15i and LT18i... So you can't use either...

Dunno Voltages and Freq for LT15i... That question should be asked owner of LT15i...
[Xperia Arc Android Development] kaz93:
Im using an Arc, however I once read that even a phone of same model have different capability in undervolting.. some may able to go -75mv and there are also those who able to go even lower since there are guaranteed variations in chips during mass production. The best thing to do for me is experiment with the voltages one at a time using app called incredicontrol (do not tick set as boot when experimenting).This is the voltages for my arc.Btw, I once use 1.2ghz for 6 months without any problem, but now back back to 1ghz since I dont play demanding games any longer.
[Xperia Arc Android Development] Daniel D.:
Is it possible to add the dalvik cache to the "format system & data" wipe option? I've to do it separately if I want to install a new ROM version - or is it not necessary?
[Xperia Arc Android Development] wedgess:
Of course it is. Ill add maybe a "format device for new rom" option or something along the lines, which will wipe all partitions.
[Xperia Arc Android Development] Daniel D.:
I thought about my question: Will the dalvik-cache automatically be deleted if you format /data?
[Xperia Arc Android Development] gu5t3r:
What's the big deal?

Mount data partition

Open console in TWRP or in AromaFM under CWM

rm -f /data/dalvik-cache/*

or if you use sd-ext, mount sd-ext

rm -f /sd-ext/dalvik-cache/*

=)
[Xperia Arc Android Development] Daniel D.:
I'm sorry, I meant that my first question about this idea was obsolete. If I use the menu option "Format System & Data" the dalvik-cache should be deleted automatically because the folder is in /data/dalvik-cache, isn't it? So my suggestion about adding the dalivk-cache isn't necessary if I'm not wrong.
[Xperia Arc Android Development] gu5t3r:
If you wipe data, dalvik-cache is also wiped...

If you had dalvik-cache on sd-ext then you need to wipe sd-ext too...

---------- Post added at 11:46 PM ---------- Previous post was at 11:45 PM ----------

If you have dalvik-cache on sd-ext and want to wipe dalvik then you need to delete all files from /sd-ext/dalvik-cache/
[Xperia Arc Android Development] Daniel D.:
Yes, I know. I only thought about the standard location. So no need for any changes to the menu. Thanks!
[Xperia Arc Android Development] wedgess:
True was talking about removing it from sd-ext though.
[Xperia Arc Android Development] rookie93:
umm what is the safest clock speed, schedulers and I/O in which you would recommend when using this kernel? when i set it at 1.5ghz, smartassv2, SIO, upon launching the game Minion Rush, it just went into a restart, then came up the notice "Unclean shutdown, values not applied" . and for the next 8-9 times, the home screen just freezes while setting up the phone, and it goes into the same thing again. running it on Ultimate HD 4.0 RC 1
[Xperia Arc Android Development] gu5t3r:
Which Phone?
[Xperia Arc Android Development] rookie93:
Xperia Arc lt15i unlocked bootloader
[Xperia Arc Android Development] kaz93:
when the phone boot again, quickly change the freq to 1ghz and do not set to boot. maybe your phone is not suitable with 1.5ghz. if you still want to use 1.5ghz(which is not recommended) you can also try to increase the voltage for 1.1 until 1.5ghz
[Xperia Arc Android Development] rookie93:
may i know how that can be done? through which apps? . i never tried this under/over volting process, so it'd be nice to learn a few new tricks too~
[Xperia Arc Android Development] kaz93:
overvolting is just a suggestion, tbh I would not recommend it since that it is more likely to make your device hotter which reduce the phone peformance and battery life. I always use incredicontrol for undervolting, do not set at boot or your device will bootloop. Increase the voltage for 1.1 until 1.5ghz by +25mv,then try to test the game with 1.5ghz, if it is still not enough, increase it a little bit more( never increase more than 75mv though). However I am not sure whether arc able to run at 1.5ghz.
[Xperia Arc Android Development] rookie93:
so if i dont set it at boot, does the values take into effect immediately, or do i have to restart my phone for it to work?
[Xperia Arc Android Development] kaz93:
the value are in use immediately.
[Xperia Arc Android Development] rookie93:
ok. thanks , currently trying a 50mv increase @ 1.4ghz , and it already looks like its responding. swiping home screen's which would usually stutter don't seem to so frequently anymore. i know people usually undervolt for better battery life, but i dont really focus on battery saving. i just want the best performance possible. that made me think of overvolting since most kernels would probably come undervolted by default..
[Xperia Arc Android Development] gu5t3r:
You can't use 1.5GHz on LT15

LT15 has stock 1GHz

LT18 has stock 1.4 GHz

Boot to TWRP, mount system, delete /sytem/etc/init.d/77lps_frequencies to reset freqs...
[Xperia Arc Android Development] rookie93:
but i checked the specifications of Qualcomm's processor page, it says MSM 8255 is capable of max 1.4ghz. so i know 1.5ghz is crossing the safe boundary of overclocking, but 1ghz doesn't seem enough for my daily usage. i actively use 4 social apps, fb, tweet, insta,whatsapp, , music listening, and also some occasional hardcore gaming, (MC4, NFS MW)

Can the free ram be increased from 355 mb ??

Our devices have less mb of ram so i suggest that free ram should be increased ;)
[Xperia Arc Android Development] gu5t3r:
NO, Enable UKSM with Low aggressiveness on LuPuS Menu... It will give you little more RAM...
[Xperia Arc Android Development] aj7400:
Can you tell me the best settings from lupus menu for performance and battery
[Xperia Arc Android Development] gu5t3r:
I think I saw people using 1.4 on LT15, but I think 1.5GHz is too high for you...

Phone probably turns off because it OverHeats...

---------- Post added at 01:18 PM ---------- Previous post was at 01:10 PM ----------

Well, we done some changes to LuPuS menu... I made UKSM Service which is optional when Aggressiveness is chosen... It turns off uksm when screen is off and turns it back on when screen is on. It enables you to use higher uksm aggressiveness with less impact on battery...

Made some changes to KernelMemoryTweaks, and added some Scheduler Tweaks when choosing scheduler...

It will be available to you in next release...

For now, enable uksm on LOW, enable KMT tweaks, use schedulers sio or cfq, use smartassH3 governor, freq 134-1516Hz with undervolt I posted for Arc S (LT18i) few post back....
[Xperia Arc Android Development] kaz93:
based on my experience ..for nfs mw..1ghz is enough,.for mc4, you need 1.2ghz..all of this with smartassh3 sio and zram..oh, and this adreno driver I found somewhere in xda. this give me 32 fps max in nenamark 2 with 1ghz.
[Xperia Arc Android Development] gu5t3r:
I've got 31.2 fps on 1GHz using these

[Xperia Arc Android Development] gu5t3r:
I've got 32.4 with yours but on iridaki's I had software renderer disabled in egl.cfg, maybe that gave me few fps boost... Will test and report...

---------- Post added at 05:15 PM ---------- Previous post was at 04:49 PM ----------

Boot loop

I tried few different versions of Lupus kernels on few different ROMs (Zelly Cream, UHD, Leonardo,...) and I get always boot loop. Sometimes it stops on Lupus logo, sometimes it stops before logo. I never went to CWM. What shoud I do ? How I can report problem ?

I have Xperia Arc.

Thank you
[Xperia Arc Android Development] jkjacek:
What device? Did you make factory reset and all possible wipes?

With LuPus to go to recovery press Up volume or Down volume key to enter CWM or T.. (forgot name and order) recoveries just after 2 wibrations.
[Xperia Arc Android Development] tompec:
Yes I did all possible wipes, I am sure. I didnt try volume keys for enter CWM just back button. Anyway it was stucked on boot Lupus logo...
[Xperia Arc Android Development] xdlol123321:
You can try to reflash the kernel. Boot your phone and when the LED become blue, keep pressing the VOL - button. Now you should be able to enter CWM ! Hope I helped you ! :laugh:

I am getting rx_wake wakelocks with this kernel.. It's draining the battery.. Any solution??
[Xperia Arc Android Development] Marmalux:
I`m curious, how did you have done all wipes since you have not accesed CWM ?

To install kernel and ROM folow this steps :

- Put Rom file on sd card

- Turn off phone

- Pres and keep presing back button while inserting USB. Blue led should be on, and this means you are in fastboot mode

- Flash kernel (Open CMD window in fastboot folder on PC and type : fastboot flash boot "kernel.img" (replace kernel.img with exact name of kernel, and the file must be in same folder with fastboot.exe).

- disconect USB

- start phone and when blue led is on pres vol-down key to enter CWM recovery

- wipe everything (data, system, dalvik, cache)

- install zip from sd-card (after selecting this option browse to the Rom file you just put earlier on sd-card)

- Boot your phone

Observations :

- In Lupus kernel case you do not need to flash modules for wifi, they are integrated in kernel, and after first boot wifi might not work but a reboot will solve it, and if still not working search few pages back on this thread to see how to reset wifi via lupus menu)

- Be aware that kernel and Rom must be compatible. I`m using lupus V16 (this thread) whit stock ICS 4.1.B.1.13

- Last time i checked, if you try to use a GB ROM with this kernel your wifi will not work .

[Xperia Arc Android Development] gpkumaran:
Working great.. Dint check Wifi.. Seemed to be laggy initially.. but then got alright.. Smartass v2+ SIO (OC to 1.6 G and UV)

then regarding the battery life.....

Have been using it for jus 2 hours or so.. but seems to be better than the kernels i`ve tried before especially with Screen off..

Here`s how:

I have very bad 3g sig in my place.. I have Data on always..

By monitoring with Current Widget,

With most other kernels:

When Screen+3g data on,the current usage fluctuates between 120 mA to 580 or 600 mA (when 3g sig is very bad)

When Screen off, it fluctuates between 3-5 mA and somewhere around 190 mA

With This Kernel:

When Screen+3g data on,the current usage fluctuates between 100 mA to 580 or 600 mA (when 3g sig is very bad) --- almost same

When Screen off, it fluctuates between 3-5 mA and somewhere less than 100 mA -- here`s where this kernel gains the upper hand i think..

@wedgess, Have you incorporated the lowering of screen voltages as someone suggested??

Sent From My Sony Xperia Arc S
[Xperia Arc Android Development] fakhreza:
Tried the v3 kernel, I must say for everyday usage experience, it's smooth :) Good work!

But just guessing, there's might be a problem in GPU OC implementation, since I still get lower 3D FPS on benchmark and games. Does anybody else experiencing this? If not, then it's the ROM problem :D

Anyway, EXT4 works now! Gonna test this kernel as for my everyday use..

Other bug i found:

When rebooting, the phone hangs up in lupus logo for a while, and then it reboots itself again, but the 2nd reboot successfully reached the main screen.

Oh, and general question. Did using .587 based kernel on .431 based ROM will affect performance or not?
[Xperia Arc Android Development] wedgess:
No I have not as of yet, but will have a look next time i'm going to release:silly:
