I kinda disagree.If i remember correctly your phone has minimum frequency of 245 with stock kernel so why increasing?I use my mini with rage kernel at 122-1024 smartassV2 governor never had any problem.I use profile for screen off settings are 122-368.Battery consumption is 0.4-0.5% over night not in flight mode and cpu spy shows 99% of that time cpu is sitting on 122 MHz.So unless your phone is heavy loaded with apps that constantly require cpu power i recommend trying my settings and test over night, you got nothing to loose after all;)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] melander:
Wow, thanks so much for the very detailed guide!

Will try it out now!:)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Running Hybrom V15 now with Rage Kernel.

So far so good.

Now, how do I set the CPU frequency?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Someguyfromhell:
I have had my minimum CPU frequency on 122 MHz for months, no problem. Phone sets the CPU frequency itself higher, when it needs more power. Putting minimum too low doesn't affect it.

I have exactly same settings.

Taskkillers/memoryautokillers etc are useless, even not recommended for Android. These close apps, that need to be running and when they start again, consume more battery.

Android is built self to kill apps, which are no longer needed in memory. It kills some apps, when free RAM amount reaches minfree level, amount of RAM that has to be always free.

If you want to improve RAM, better try out V6 Supercharger, link in my signature. It changes the minfree amounts to higher of lower, which one you want. Either multitasking, lowers minfree amount to allow more apps to work at one time, so you can access these easily, without the need of reopening. Or higher minfree amount, to keep more free RAM.

I personally have chosen Balanced.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] T3sla:
And i use V6supercharger too among others scripts;)Next project undervolting.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Kira.Lawliet:
It does affect it in a little way; putting it up on low frequency -> phone will scale frequency according to needed -> what does it use to scale? -> uses abit of power to scale according to needed; so it's logical to why not set it to a mid frequency when it consumes the same volt therefore not wasting a bit energy to scale up or down when needed; of course' the number of your apps/running services affects this so it depends; you might hardly notice any change at all. It just that it's optimal but I'll not argue with this since we don't ran out of battery anyway on travelling eh? :D

-reference #1, #2 read more have fun testing
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] T3sla:
Yes but cpu power from my poor knowledge depends from frequency, so when you set a 3 times higher minimum frequency even if voltage is the same you'll have 3 times more power consumption when idle.I don't think that scaling cpu consumes more than 3 times power:)BTW very interesting threads you provide us, did some reading so far and definitely gonna read the whole thing:D
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kevincaja:
kindly read this thread:

Q. "I'm going to set scaling min freq as 100 mhz because my kernel supports it. Hope there's nothing wrong in doing that."

A. Wait! You may want to stay away from using 100mhz during screen-off or screen-on states for three reasons 1) It seems 100 mhz uses more power than 200 mhz. According to tests, 100 mhz accounted to 1 W / GHz and 200 mhz to 0.7 W / GHz, when both the cores were online. 2) 200 mhz can finish same task faster compared 100 mhz and thus hit deep idle soon. 3) 200 mhz is the 'sweet spot' of frequency in SGS II. ie, the frequency used in the calculations based on the optimal energy to run (Ex: In Milestone it's 550 MHz). So , 'energetically efficient' frequency for our CPU is 200 mhz.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kevincaja:
thanks for the link to V6 Supercharger, now my phone is lag free :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] melander:
Thank you again for the very detailed explanation...

Currently trying out your recommendations...
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] T3sla:
That's maybe true for SGS II, i'm not sure about xperias so propably the best way to know is testing;)I'll try different settings when i have time and post the results.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] dumraden:
Exactly What T3sla said. All links above are for devices other than our Xperia's. We use different boards, different, CPU's blah blah blah.

Unless someone does an extended test on our devices, making judgments based on other devices is silly.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kevincaja:
your probably right gonna test if making the min freq. to 122mhz does really save battery on my WT19i. thanks anyway :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kevincaja:
oh and btw, hybrom v15 does not include a Stk.apk(SIM Toolkit app), you must integrate it via WinRAR, or via Root Explorer(if you dont want to reflash), you can customize any ROM to your liking, just search the forum for tutorials :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kevincaja:
So guys, lets talk about undervolting, i installed SetXperia and Stability test on my WT19i, will post result soon :)

current SetXperia voltages:

122Mhz = 750mV

245Mhz = 850mV

368Mhz = 850mV

460Mhz = 900mV

576Mhz = 900mV

652Mhz = 900mV

768Mhz = 950mV

806Mhz = 950mV

921Mhz = 1000mV

1024Mhz = 1000mV

checked the stability of every freq. and seems stable for me, and boot friendly :)

can you share yours? :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] melander:
what is STK used for?, I do not use my phone for a 3G connection, mainly just for calls and text

integrate it via WinRar? you mean like at it to the hybroman rom zip file?

can i just install those as apks?

havent tried root explorer yet also, haha

Thanks Kabayan!

My wife is from LC, Quezon.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kevincaja:
STK is used to access your simcard's menu.

e.g.

Pasaload

Smart Money Padala

Smart Buddy Balance

etc.

STK is only needed if you use your simcard menu to do money transfers, check remaining balance etc, in a much easier way, without manually texting codes and memorizing special numbers :)

(SAFE AND EASY METHOD)

download root explorer lite in market

Use root explorer to copy paste stk.apk to this location:

/system/apps/

or you can manually add Stk.apk to the ROM via WinRAR and wipe all data and cache(you loose your settings and apps), you have to download apps again or you can backup apps via Astro filemanager or Titanium Backup.

EDIT: you can install Stk.apk as an app so no root explorer or WinRAR required. If you ever run into errors, you really have to install it via root explorer or integrate it via WinRAR :)

enjoy :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] melander:
oh is see now,

i actually went ahead and look for that stk.apk file and i found one under the hybrom rom thread stk.apk and install it directly like any other application.

is this any different from the one you attached here?

i installed rage kernel. i like the default sony erricson logo at startup.

flashed the boot animation from v13 and stock font.

im seeing a big improvement with battery life when screen off, around 1% - 2 hours, before it was just 1% - 1 hour

i set the cpu governor to smartassv2, 122MHz for the screen off, 245-1024MHz setting

and i/o to noop, 2048 cache

any other suggestions?

do you overclock yours?:D
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kevincaja:
well the one I attached here came for the original WT19i stock ROM, other Stk.apk apps have problems so I extracted mine from the original ROM(WT19i).

At first, I did overclock my WT19i to 1.2Ghz max then went up to 1.6Ghz, stable and no overheating, but again, less battery life, so i went back to 1Ghz, since i don't have that much apps on my phone :)

You can try undervolting the CPU via SetXperia(available on Market for free) and Stability test(which is also available in the market for free) to check the stability of your phone

So probably the easiest way to speedup your phone's CPU performance is to overclock around 1.2 to 1.4 ghz without undervolting(for stability), or if you really want to undervolt and just to be safe with your CPU temps, just experiment with SetXperia and Stability test, and find the sweet spot for your phone.

NOTE:

-make sure to backup of your apps, settings etc before doing any undervolting.

-just don't keep your max freq. to 1.6Ghz or 1.8Ghz for very long time, specially when you have alot of background apps and you constantly ramp up the CPU to max, there's a risk of damaging the CPU's BGA connections to the board due to overheating which will make your phone useless.

Oh and btw, I did make a test of setting my min freq to 122Mhz, results are quite good but with small problems in MP3 playback, sure it gives me the best standby time(screen sleep) around the same as yours 1% per 2 to 2.5hrs but when I play high bitrate MP3(192kbps), it stutters. So I reconvert it again and made it 128kbps, so for now stuttering is gone. I did try converting MP4 to AAC(.m4a) using Winamp(didn't try iTunes yet) to convert it to AAC but the bass is distorted, even in original stock firmware, probably a bug in sony ericsson's firmware. Call seems to be stable, no drop calls at all when screen is off, probably because I don't install alot of apps :)

so enjoy and goodluck, for now, I'm contented with the 1Ghz freq :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kevincaja:
BTW melander, what brand of micro sd you're using? I just bought a Kingston MicroSDHC 8GB Class 4 card and I'm really disappointed with the write performace, :/ but the read performace is good though :)

take a look at the attached pics :)

some forums say that new SanDisk MicroSD Class 4 or Class 6 gives better write and read performance.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Someguyfromhell:
That has nothing to do with this topic...

MicroSD cards are all fast enough, music should be no problem.

Now, on topic....I have kept minimum on 134 Mhz for the last 3-4 months, never had a problem. Governor is mostly smartassV2, maximum is 1Ghz, sometimes I use 1,2 Ghz.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kevincaja:
sorry for the post about the microSD :/

anyway what's your battery life at 1.2Ghz?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Someguyfromhell:
I reload my battery every night anyway, even though some days I use phone more, some days less.

Will do a test in the following days.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kevincaja:
thanks, will wait for the results :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] melander:
OK, i will download that stk.apk that you have uploaded. thanks.

i actually changed my kernel from rage to X.

tried to install the zram script and got stuck at the bootanimation.

had to reflash again X kernel and ROM.

All is well now, at least i was able to reconfigure the rom much faster now with my desired settings, :D

Tried to run it on 1.6GHz just to run a benchmark, was really impressed with the improvement, but would not stick to that setting since the battery drain is massive and for reliability reasons.

Currently testing out it on 1.2GHz, ondemand and bfq via no-frills.

Just a question, about deep sleep, i checked my battery status after 4-5 hours on standby/screen off. i noticed that there was no awake and screen on times so i think, thats good. however, phone signal is steady red line, is that normal? <<< it was just at home that the signal was red, here at work it was all green, hehe

Will probably just go back to 1.0GHz after testing out the phone on 1.2GHz.

I currently have the phone on 134 mininum, have not checked out the playback performance yet. Most of my mp3s are 320kbps, so that would be a good test scenario.

Here is just some apps that I use.

Alarm Clock Plus

GO SMS

GO Contacts

Antutu Benchmark

Simi Clock Widget and Simi Folder

Facebook

Hopefully none of these add up to the battery drain while on standby.

I bought my SD card last December from Micro Valley Pacific Mall.

Got tired of waiting in line at CD-R King.

Ended up buying a Microdia 8GB Class 4.

Indicated on the packaging is that is used on most Samsung phones.

Also says 66x on it, maybe write, not sure.

The performance is quite unpredictable, im getting as low as 3MB to 9M write.

Not sure why it is fluctating...

I thought Kingston was a good brand, i am currently using a Kingston dt101 16gb g2 flash drive. Based on the reviews it gets faster speed with large files.

Sandisk is definitely one of the best brands, but for a price.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kevincaja:
changed my kernel too from rage to X kernel, sleep performance is quite good, no more mp3 playback stuttering at 192kbps :)

and the benefits of zram is quite noticeable(since it uses the free RAM as a swap, instead of the flash memory), i didn't install V6 supercharger, since i have lots of free RAM and i don't install a lot of apps.

the CPU governor is still at SmartAssv2 and Noop for I/O, 1.018Mhz max and 134Mhz min. I also set the read_ahead_kb to 2048kb and i noticed immediately that my SD card read speed increased from 14MB/s to 17MB/s (average from 5 times of test using SD Tools and AnTuTu)though write speed is still the same(4-4.2MB/s) :/

think I'm gonna buy those SanDisk 16GB class 4, badly needed fast write speeds, specially at 4K to 512K write. :/

I also noticed that when in deadline I/O, my SD read speed decreased from 17MB/s to 15MB/s, SIO managed 15-16MB/s read speed on my Kingston MicroSDHC 8GB class4 card, hadn't test the internal memory performance though.

about the phone signal, is your network set to use WCDMA/GSM or GSM only?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] melander:
i am not seeing zram in terminal app sir, how about you?,

i actually got problems when i tried to flash the zram script from x kernel thread.

getting boot loops, had to reflash the rom to fix it.

still finding the right combination on mine, tried ondemand and bfq, using no frills

i think i have a problem with my sdcard, just gonna save up for a 16GB or higher, hehe

network was set to wcdma/gsm, will just switch it to gsm...

doing some backups now thru titanium and cwm, just in case...
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kevincaja:
Procedure:

1. flash kernel via flashtool or yung SE Bootloader Unlocking v1.6 by quangnhut123(easy and fast to download)

2. power on your phone and enter CWM

3. clear and wipe mo yung data/reset

4. wipe partition cache

5. install hybrom v15.zip

6. install wlan module(if your using X Kernel)

7. then install zram.zip

8. go to advance and click wipe dalvik cache.

9. reboot your device :)

after setting up everything, check if your using swap:

1. open terminal emulator

2. type "su" to enter superuser mode(a superuser prompt should appear for the first time use.)

3. then type "free" to check if your using swap.

you can also type:

cat /proc/swaps

to check your zram partition.

NOTE: some people may not benefit in using swap. And take note also that zram uses some CPU cycles in compressing and decompressing data to zram partition to the ram, which may slightly decrease battery life.

enjoy :)

EDIT: i tested BFQ I/O scheduler and I see a little improvement in read speeds on my Kingston 8GB MicroSD class 4 card, take a look at the attached pictures :)

performance is quite similar to noop if not, sometimes worse than noop when repeating test. I still choose noop since it gives me a stable 19 to 20MB average reads, and performs better in 4k and 512k read and write, noop also loads my pics and vids fast on my gallery :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] melander:
will probably do the reflash on my phone once Hybroman V16 comes out....

will test out current settings, update SU and try to run some test on my SD card also.

thanks sir!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Someguyfromhell:
Tried a day with 1Ghz and another day with 1.2Ghz, tried to keep about the same usage, didn't notice any big difference in battery life.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] melander:
thanks for the update.

it seems it is really dependent on what apps are installed and what is running in the background.

i can see the there is a new version of x kernel?

any noticeable improvements?

[Android Q&A, Help & Troubleshooting] Shurafa:
I am not sure how this happened but it is really great and I would love to recreate it in the future.

I have an Galaxy Tab 7.7 Running the stock ROM from Hong Kong.

I installed Google Voice from the market and have it syncing with my work number. It is able to send and receive texts from my work number. However somehow it has been able to receive texts from my personal GV account as well. Replying to these texts will reply from my work number.

Edit:

Seems as though an app called Talkatone is the culprit. I have my personal GV account tied to this app. Once I select the "Check SMS on this account" option it will somehow forward messages to my Work GV account even when Talkatone is off. It only forwards messages as they happen it does not seem to cache or sync them so if my phone is off and I get a personal SMS it will not show when I turn it back on.

I wonder if there is a more elegant way of doing this? I would love to permanently be able to forward all my personal SMS messages to my work number if this is possible.

With the help of another xda member. (Halfcalf) we now have hulu plus for our device. All you need to do is place the extracted files from the zip I will upload into your titanium backup folder then restore the app AND data. All three files must be in the titanium backup folder. Not just one big folder. It took me a few tries but it works. I'll answer questions as your post.

I also noticed that after the first time it said unsupported..i just went back to titanium and restored the data again..if you have any buffering problems..that on hulu not the app.

Im currently watching hulu on my tab as we speak
[Galaxy Tab 8.9 Themes and Apps] knipp21:
Please post back if this works for you.

176 views and no replies? Goodness this forum is a tough crowd.
[Galaxy Tab 8.9 Themes and Apps] trampledbyturtles:
Works great so far, occasional force close while scrolling but that's the only issue that i've noticed aside from the dreaded endless buffering which you had already mentioned is on Hulus end. Nice work...
[Galaxy Tab 8.9 Themes and Apps] knipp21:
Thanks yeah that's an older apk..I'll update mine and post a new one. The new one buffers allot too but may have less force closes..I've been using this since Hulu first came out and only posted it here because someone in my other thread said it worked on their tab.

Do tab need to be rooted ?
[Galaxy Tab 8.9 Themes and Apps] knipp21:
The app used is "titanium backup for root users" lol
[Galaxy Tab 8.9 Themes and Apps] warttack:
OK this is good news as you don't need to install an app from other sources. It can be downloaded straight from the market and it works on ANY device.

So download the latest hulu plus from the market.

Download any root file manager. I use root explorer but any other file browser that let's u edit data folder would do it.

Open file browser and go to /data/data/com.hulu.plus/shared_prefs and open cSPrefs.xml

Now in that file there's a huge string named lastTimeOut.

In that string look for ns_ap_device= and replace what's in between that and &. In my case I'm running cm9 so I have ns_ap_device=p5& where p5 is the devices name. Change that to a supported devices name, I used Xooms device name Stingray so the end result will be ns_ap_device=Stingray&

Just replace that part without touching anything else. Save the file and reopen hulu. It should work now.

That will work even it the app gets updated and its an easy fix if you clear data or something.

Let me know how it works for y'all and remember to hit thanks if it helped you :)

enjoy your hulu.
[Galaxy Tab 8.9 Themes and Apps] dingurt:
