Hey guys.
Iv been reading a few things regarding fast dormancy and switching it off improves battery life and network speeds, but im unable to find this hidden dialler menu.
*#9900# doesn't do anything, when I type it, it just disappears - no menu comes up.
What am i missing ?
Im on Lite'ning ROM 1.5 KF2 modem and Kf2 kernal
Thanks guys
*#*#9900#*#*
Thanks for the reply but that also doesn't work, nothing pops up at all....
Make sure that you are using the stock dialer, not another one you have installed from the market afterwards.
It is stock dialler, I haven't changed that ever. Im starting to think maybe its network related ?? Im with Optus Australia, maybe they don't support it or maybe I have different dialler codes ?? Thanks for our help
Network errors while sync or Dropbox
When Fast Dormancy is disabled; I keep getting network error messages while I sync Dropbox files to my device. Whne enabled, everything is fine.
I did not notice any such issue with other data applications.

That works for me, and is how I disabled fast dormancy a couple of weeks ago. I can only assume that it's something to do with your ROM or FW.
I'm on stock, KE2.
FIXED!!
I fixed it by installing Infusion 1.2 by Nitroz ROM his rom is awsum !! now my battery lasts even longer and have wayy better network speeds.
his rom is can be found here http://forum.xda-developers.com/showthread.php?t=1152693
Thanks guys for the help anyway
Hi all,
before I bought my SGS3, I owned a SGS1.
For the SGS1 there was a secret code which allowed me to switch off any HSDPA / HSUPA traffic but limit the data to pure 3G UMTS.
This saved me a lot of battery, so I always used it.
Ref: http://forum.xda-developers.com/showthread.php?t=837716
The code was: *#301279#
Unfortunately this code stopped working already with the SGS2, so it does also not work for the SGS3.
Does anybody know some secret codes, might be the one I am looking for is contained?
Many thanks
Andi
Found the solution
Hi,
I found the solution myself and posted it in the FAQ section already:

I've read in various places that if the network has the Fast Dormancy feature enabled, but the phone does not (or vice-versa), this will have a negative impact on the battery life of the phone.
Can anyone substantiate this claim?
Also, is there a way to tell if this feature is turned on in the firmware of my phone? I purchased my phone unlocked from an independent retailer, so it doesn't (AFAIK) have a network specific firmware image loaded.
I'm also unsure if my provider (Vodafone Australia) has FD turned on or off on their network or how to tell.
Everything you need to know:

Hi
I've got that app from Syah and also have the same kernel but it doesn't even start - have any ideas?

This is the follow up thread to:
Fast Dormancy -- Save Your Battery from 3G Drainage
http://www.youtube.com/watch?v=O8L50sCY7CI
This is a thread to discuss your findings and concerns about Fast Dormancy.
Feel free to leave questions for me, I will be constantly monitoring this thread.
****NOTE*****
There is an original app by Gokhanmoral, which effectively disables Fast Dormancy on the Galaxy S3 (ONLY TESTED ON i9300). Please refer to the description on market app link below for future compatibility.
https://play.google.com/store/apps/details?id=com.gokhanmoral.fastdormancytoggle.i9300
Supercurio is creating an app that disables FD, but also ads separate diagnostic functionality.
Yeah so Erica spoke about an application we developed when studying the Fast Dormancy and RRC states.
In order to experiment and understand all about FD, we had to developer a new tool also allowing to enable/disable Fast Dormancy on several Samsung phones, and apply changes in real times, including when tuning Fast Dormancy timers.
Requiring root depending on the device itself, its main purpose it to help you analyze if the network you're using supports fast dormancy or not, then allow you to set reasonable settings providing satisfying battery performance while keeping the network latency low.
Be sure you watch Erica's video as she will explain the technical challenges behind 3G power management better than I could.
Phase 1:
Today's application is very simple:
It provides an easy access to the useful Samsung proprietary ServiceMode page displaying RRC states and also advanced network SNRs.
Download preview app from Google Play
Voodoo RRC Tool source code on github
Note: the app kind of suck and as you'll notice it benefits from no UI design at all yet
Contributions are indeed welcome.
Phase 2:
Automatize the FD detection process in order to help you telling us which kind of network behavior you experience with your carrier.
Phase 3:
With fast dormancy carrier database, recommending automatically optimal settings.
Add support to enable/disable and choose Fast Dormancy timers on non-Samsung phones.
Phase 4:
Reverse-engineered Service Mode in order to build statistics of RRC state used, maybe to guess automatically if a network supports FD or not.
I'll probably not go this far but it might be interesting to develop this, not only on Samsung phones but on many more.
Once again contributions will be welcome here too.
I hope you'll like this joined XDA TV & development effort, which aims to investigate a topic, share knowledge and provide tools for everyone's benefit.
Hopefully its only the first collaboration among many. I'd like to encourage other developers as well to consider XDA TV as an extension of everything we're doing here, and interact with videos producers.
Guess i'll be the first to reply. Thanks for the info, i really learned alot. Keep up the good work erica.
Cheers!

There was an unexpected glitch in one of the demo, the one explaining how to diagnose if Fast Dormancy is implemented or not by your network.
Concretely the actual demo was exhibiting a different behavior from our previous observations, so to be completely sure to guide you in the right direction we're re-investigating.
Except this part where there was doubt everything was perfectly accurate: Erica video shall be back soon on XDA TV once we figure it out
Thanx sc,nice tool and great work,even though I was expecting another app from u,hopefully that will come eventually
Good to see you're back.
Not working??
EDIT - the app by Gokhanmoral on the OP works perfectly now! (on my sgs2)
ignore the text below
The app doesn't show any output for me, is this :
1: Because FD is not available with my Carrier? (UK Vodafone)
2: Because I'm in the UK?
TIA

*Either reply in this thread or PM me if you need any further info/testing

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Codes don't work on AOSP/AOKP ROMS's (apparently)
I have always wondered if AOSP on for example the galaxy nexus supports FD, There is a general lack of information, it looks like it should, but I don't know.
It would be great to find a way to gather this sort of data on AOSP or other devices, no idea if it's doable though.
Great video series, FD is under documented and there is a lot of misinformation and unbacked assumptions
As far as networks go, unless the documentation is incorrect, my network (3UK) have FD enabled, I am unable to back this up with data, as I sold on my sgs2 a while back now
I can't get any information about FD in my Galaxy Nexus with JB
Yes good question about AOSP.
It's possible Samsung RIL is still reading fast dormancy activation status and timer values from somewhere in pure- Google devices.
Samsung devices running AOSP instead of Samsung firmware must still read the FD configuration parameters, as they're rocking the same RIL binary code.
This is definitely something to investigate, I'll take a look but feel free to report your findings, that might be useful features to add to RRC Tool.
Tip: you can search for strings in libsecril*.so in /system/lib and attach strace to the rild process : both give a lot of clues
On my Galaxy Note the code do access the service menu is *#*#0011#*#*
Does this depend on the radio version? model? network?
Awsome Three uk support Fast Dormancy
I have been poking the rild with strace, at the moment the output is refusing to be piped to a textfile, which is annoying, will work on that later.
Funny thing is that it runs for a bit then crashes it, have to toggle airplane mode to get network back, its most likely me not running strace with the right parameters though.
if i enable FD in the app and set the timer to 15 sec then nothing changed in *#9900#. there ist the curent status of my FD stil disabled.
okay so i enabled both and charged phone to 100% and toggle mobile data and was watching the battery. in half an hour I lost 2% of Bat.(did nothing .. only get few emails via push and wrote an message via whatsapp)
than i checked BBS and in the section kernle wakelocks i get an wakelock named : "sercril_fd-interface" with an time of 22m ( FD was anebled for 30 min) witch take an total wackelock of 50%?
now i kinda dont it what should i do ? will watch again 30 mins and will check than without FD .

Hello angelofmusic, I have a Samsung Galaxy Note GT-N7000 currently running on CheckROM Revo NoteHD v5. Upon accessing SysDump, there is an option - Enable fast dormancy(Current State : Disabled).
Thus, I suppose I would not require the prescribed app, would I?
:silly:
What is the appropriate stepwise testing procedure/methodology that you suggest I follow?
Thanking you and awaiting your response.
So will FD save me some battery life if I enable it? What about black crush how do we fix that?
You might want to note that Gokhanmoral's app was based on the guide here: http://www.androidnz.net/2012/06/at-your-own-risk-how-to-disable-fast.html
Telstra RRC states/timers
Telstra does the following on 850MHz (MCC/MNC 505/01):
DCH (T1 1s) -> FACH (T2 30s) -> URA-PCH
Three/Telstra does the following on 2100MHz (MCC/MNC 505/06):
DCH (T1 5s) -> FACH (T2 10s) -> URA-PCH
Didn't time the T3 timers (long).
If you're on Telstra, the fast dormancy timer will force the IDLE state (for both networks above), and you will miss out on the benefits of the PCH state.
Background info on Australia 3G networks:
Three + Telstra had a reciprocal network sharing agreement for years (Telstra 2G 900MHz + Three 3G 2100MHz)
Three + Vodafone merges.
Three network shares with Vodafone 2G (and wiith Vodafone 3G this month).
Three/Telstra network sharing agreement ceases end of this month.
I think Three network would likely stay as a seperate network (rather than merged), in which case the states/timers would likely be the same.

Confirm..yes me too on my Galaxy Note code is *#*#0011#*#* to enter the Service Mode
maybe it gonna be awesome if possible to direct from the Voodoo RC tool..btw that app is awesome for starting
keep a great work for you Supercurio :good:

as long as your carrier provider support that FD ..
black crush ? hmm i think that a different problem..this thread is discuss about networking not the Screen Colour
....
finnaly ..
before trying your Voodoo RC tool i check the RRC state behaviour with default setting ( enable fast dormancy from *#9900# )
and the result is:
DCH to FACH pretty random timer ( some times 8s, 15s ) .. and very quick from FACH to PCH -/+ 5 sec and stay on PCH never goes to IDLE state
then i try voodoo RC with guide from erica video (thanks erica)
1. when i enable and first try the 1 sec FD with policy then back to test
DCH to FACH still ramdomly but never reach above the 10s ..and still very quick switch from FACH to PCH and stay on PCH state until the same process repeat PCH to FACH then DCH
2. then i try the 10 sec FD with policy and tested
DCH to FACH still ramdomly but sometimes lil bit longer the 10s ..and still very quick switch from FACH to PCH and stay on PCH state until the same process repeat PCH to FACH then DCH
.. then i decide to stay in that setting and see what happen..until more or less 5 h i check with BBS that secril fd_interface on kernel wakelock is 2 h more or less is about 51% and yes my phone cannot enter the deep sleep by that ( i forgot to capture it sorry )
my question is : is that mean my carrier provider deffenetly didn't support the FD or i did something wrong with the step .. coz last time i disable the fast dormancy ( with FastDormancy toogle by Gokhanmoral ) i never saw that secril_fd process so high..
but i'll try looking for and test again
again thx Supercurio and Erica
This is a great thing Erica is triying to do!
I wrote a guide in Spanish for people in South America or Spain:

Hi.
I suspect that my current network operator doesn't support the 'fast dormancy' option for mobile data, so I've been trying to find a way to disable it, but to no avail.
I read that if your phone has fast dormancy enabled but the network operator doesn't support it, that means bad news for your battery, which I've found to be true in my case.
When I'm off wifi and on mobile data, if I leave the phone with the screen off for long periods of time, I get the "msm_hsic_host" wakelock, which I've found to be directly related to 'fast dormancy'.
I tried using the *#9900# dial code and disable it there, but it seems like the option is not available in there anymore.
How do I go on about disabling fast dormancy in a non-rooted phone?
My phone: Samsung Galaxy S4 i9505 (non-rooted)
ROM: Stock Lollipop 5.0.1
Kernel: Stock
P.S.: For anyone wondering what 'fast dormancy' is, here's a video explanation for it.
I don't think you can on a non-rooted phone.
