You are right my neghbor, i was try this on 9300 (S3) some month ago, and dont help this apk.

Probably dont help on 9505 too. It is depending from netvork status and technology.

My phone, with FD enabled, says RRC: IDLE, Band1.

With FD disabled, it's the same, so I reckon it has no effect.

The app is called FastDormancy Toggle, made by Gokhan Moral, available for free on the Play Store.
[Galaxy S 4 General] TheWizardbc:
Did you restart the phone after changing fd?

Fd off: DCH (H+) --> (3G) FACH, after ca 1 minute changing to IDLE

Fd on: DCH --> IDLE

Does FD work on my network?
[Galaxy S 4 General] gavin-phelan:
try the app and tell us
[Galaxy S 4 General] robogo1982:
Well, I disabled fast dormancy with Gokhan's app, but I still see fast dormancy wakelocks in BBS. Odd.

I might have to check into this feature a bit more.

oh yes sorry I forgot
[Galaxy S 4 General] TheWizardbc:
I did use the app, but I don't know what normal is for FD. Is that the DCH --> IDLE? I thought it was : DCH --> FACH --> RCH --> IDLE.

Couple of months ago I wrote an email to my carrier about it and got confirmed that they don´t support fast dormancy.

So, everyone on VIPNET Croatia - go ahead and disable it, they DO NOT SUPPORT it.

[Galaxy S 4 General] cybdani:
If your carrier supports fastdormancy, DON'T disable it or you battery starts to drain very very fast: You can test it by disabling fastdormancy, force wcdma, load a web page and keep autosync enabled. You will see...

If your carrier is not supporting fastdormancy, doesn't matters if you disable it because phone is not using it.

Hope this helps.

In spain, vodafone supports fastdormancy. It's the only carrier in spain that supports it.

Maybe you can try to call again....
[Galaxy S 4 General] Gillion:
Put your phone into WCDMA band only

Dial *#0011#

Look at the line that says RRC State.

It should say IDLE or switch between

DCH and IDLE really quickly after all data transfer has stopped (orange and green arrow not on)

If it stays in DCH and/or especially FACH longer than 5 seconds without any data activity you do not have fast dormancy active from your carrier.

RRC State = FACH for long periods of time indicates your carrier does not support Fast Dormancy.

[Galaxy S 4 General] StuartTheFish:
I'm on 3 in the united kingdom. When doing this to check, mine generally stays on CPCH, with brief changes to FACH and back within seconds, every minute or so. It never says IDLE. So does my carrier use fast dormancy or not?

[Galaxy S 4 General] omniwolf:
Hi Guys,

I did a bunch of fast dormancy tests on my old i9305, you can read the results HERE.

Suffice to say:

Even if your carrier has fast dormancy, it's not always a good idea to have fast dormancy enabled on your phone. My carrier has it enabled, but I get better battery life with it disabled on my phone. You'll have to test and find out for yourself.

I believe most of this fast dormancy stuff is only relevant to 3G/HSDPA, 4G uses a completely different way of connecting, so it's not relevant. Yes you'll probably still see a fast dormancy wakelock even when it's disabled on your phone, but it's probably some 4G stuff happening. If you're testing this, make sure you disable 4G on the phone.

The fast dormancy app didn't work for me, I had to use the instructions HERE.

How to work out if your carrier supports fast dormancy? How to prove that 4G ignores it? Have a look HERE

---------- Post added at 05:57 PM ---------- Previous post was at 05:46 PM ----------

no

if you look at my results, the actual cycle won't change when you turn FD on and off, it's just the amount of time the phone spends in each mode.
[Galaxy S 4 General] ggp759:

[Galaxy S 4 General] cmd512:
Eh, which is why you shouldn't just copy from the interwebs without doing a bit of research, this is actually incorrect / backwards. Nothing worse than misinformation... well actually I take that back, spreading misinformation is worse, see below:

1) IDLE state = no fast dormancy. This is the original old school 3g switching method that went DCH - FACH - IDLE. Problem is, FACH isn't very battery friendly, and switching out of IDLE was not optimal.

2) PCH state = fast dormancy, currently in Release 8. Now, it'll go DCH - FACH - PCH. Your device won't stay in FACH long (good), and will enter a low battery readiness state PCH that can quickly ramp back up to DCH (also good).
[Galaxy S 4 General] pitastrudl:
so you're saying that disabling fast dormacy is just another myth, just like wiping batterystats would "decrase" battery drain?

aynways i cant use the app since it says my device isnt supported. does that mean my carrier also doesnt support it?

im running cyanogenmod 10.1. also the code *#0011# wont work for me :s
[Galaxy S 4 General] cmd512:
No, that's not what I'm saying.
[Galaxy S 4 General] sunish:
I don't know about battery stats , but deep discharging battery DOES decrease battery drain.

Couple of days back, my phone got discharged to the point where even after connecting to the charger, it took 4-5 minutes to show that it is connected to the charger. After powering on, the battery stats/history was still there, but surprisingly the battery drain has stopped.
[Galaxy S 4 General] pitastrudl:
yes i know that, since decreasing the battery to complete zero can "shock" the battery, thats why its wise to charge it when it reaches about 10-20%, thats one of the points of having a "battery left" reminder. but lets not talk about something off-topic :).

Regarding [MENTION=1984051]cmd512[/MENTION]'s post, ive read it multiple times and i see that i understood it wrongly. As far as i've understood it, disabling FD makes the 3g mode swithcing stay in one specific mode, so it wont jump on over the battery draining one and to the PCH one, thus limiting battery drain?
[Galaxy S 4 General] cmd512:
You should only disable fast dormancy if your network is not using it, which means you see IDLE modes. Fast dormancy enabled networks will NOT have IDLE states.

My original response was targeting the post I quoted as that poster posted the opposite, which is flat out wrong.
[Galaxy S 4 General] pitastrudl:
Thank you for the deep explenation. I've contacted my carrier, and waiting for a reply.
[Galaxy S 4 General] afilopou:
First of all thank you for the infos. I am trying to understand if my carrier has FD enabled and info finding in google is a bit old.

I am running google edition for i9505 and fast dormancy is enabled from phone's side.

Typing *#0011# i can see the RRC states which are (browsing>doing nothing):

RCH>FACH (stayed in this state for around 30secs)>UPCH .I see no IDLE state (means my carrier supports FD.Correct?).

Do you think that i have to compare it with FD disabled (from phone's side)?

Thanks a lot
[Galaxy S 4 General] StuartTheFish:
So my network DOES use fast dormancy? I was told just two pages ago that it doesn't, because I never saw IDLE.

[Galaxy S 4 General] omniwolf:
Hi guys, please have another read of my post (and it's links) HERE, it explains most of your questions.

Not necessarily, all FD does for me is change the timings of the RCC states. The cycle remains the same

This is not true. My network has fast dormancy, but I get better battery life with FD DISABLED. Read through my link above and see the proof if you wish.

Since when will FD enabled networks not have IDLE? Do you have proof of this? As I understood it the phone will only go into IDLE when the screen is off, so you can't monitor it.

If i disable FD on my phone, it will still not go into the IDLE state..

Read my thread above, and you can see how I tested for FD on my network. Basically get the timings for the cycles with and without FD. If they differ, then FD is available on your network.

I don't believe this is necessarily true...

read my link at the top, you can do it manually by editing the phone databases.

But you still have fast dormancy. Which one is kernel wake lock for fast dormancy? Fast dormancy or qcril_fd?
[Galaxy S 4 General] AMDPOWERFIST:
Fast dormancy is the one i was looking at. If you look at my post above, it was sitting at 2hours+ before, now its only in the 1min20sec amount.

It seems that even when its disabled it still sits in the kernel but isnt being used. Possibly just polling or something. I am not sure. All i know is that before i disabled it my battery was dropping like crazy, now its turned off its going strong ~1% per hour
[Galaxy S 4 General] echo_rc:
Here's my bbs screenshot
[Galaxy S 4 General] AMDPOWERFIST:
Yeah mine was the exact same. If you run the FD disabler app, it will cut that number down to minutes rather than hours. Much better for the phones "deep" sleeping function. The more kernel and partial wake-locks you can cut down or their timing durations the longer the battery will last.
[Galaxy S 4 General] marci4na:

[Galaxy S 4 General] marci4na:
yes i have! and for this reason i am asking that beacause disable fast dormancy for s3 by gohan is NOT working. is proved is not working.

even if fast dormancy is less present in the wakelock it means it hasn't been disabled.
[Galaxy S 4 General] StuartTheFish:
As has already been said if you have read the thread, it's gone from hours in bbs to just minutes instead, which shows it has helped. It'll still be there in the kernel, but it'll get stopped by the script that the app makes.

says its disabled but still see these kernel wakelocks on a freshly charged battery after about 2 hours and a reboot after setting dormancy to DISABLED

msm_hsic_host (25%)

fast_dormancy (15%)
[Galaxy S 4 General] StuartTheFish:
Of course it's still there as it's in the kernel whether you use the app or not. But if you look at the time it's been there for, you'll see it's only a few minutes instead of a lot longer beforehand.

See my screenshot below for example. It's been on for over 10 hours, but the fast dormancy wakelock has only had around 13 minutes of activity in all that time:

Before installing the app and disabling fast dormancy, it would regularly show as being active for hours during each cycle.
[Galaxy S 4 General] aliendna99:
on mine its the exact same. 15% with FD enabled

about 15% with FD Disabled

yours only is a few Percent

[Galaxy S 4 General] gsmyth:
I have checked and my network (virgin mobile UK) does not appear to support fast dormancy so tried the toggle app and disabled it. However I have checked better battery stats and fast_dormancy has appeared under kernal wakelocks. Its only for 4seconds, so could it just be that it was triggered as part of the disabling process?

With data enabled i see DCH, FACH, CPCH when in service mode and then when I switch off mobile data it changes to IDLE. Is this all OK (ie fast dormancy is now disabled OK?).

does three uk support fd does anyone know???
[Galaxy S 4 General] Rob2222:
Yes, but you do NOT save energy now.

You maybe don't have any FD-wakelocks anymore (which maybe saves some cpu time) but now your phone idles for 15 seconds in the FACH state after _each_ data transfer.

For this you must know, that FACH consumes around 50x the energy of the IDLE state and DCH consumes around 100x of the energy of the IDLE state. So cause of that you want to reach the energy saving IDLE or PCH state as soon as possible.

IF your network cell is configured fast dormant it will send your phone fast (maybe <5~10 secs) back from DCH to IDLE/PCH. In this situation you can switch off the "phone-initiated" Fast Dormancy of your I9505 without consuming more energy.

IF your network cell is not configured fast dormant it will let your phone hanging around 15-30 secs in FACH state. And in this situation it is better to keep the "phone-initiated" Fast Dormancy enabled cause your phone switches then direct from DCH to IDLE in 5 seconds.

And yes, Fast Dormancy CREATES Fast Dormancy Wakelocks (CPU time) but at the same time "not hanging 20 seconds in FACH after each data transfer" saves you more energy in the MODEM than you have to pay for the CPU time.

People that having much background traffic often seem to think Fast Dormancy is bad because they see FD-wakelocks and having poor battery life. But the cause for the poor battery life is the huge amount of background traffic that uses energy for the modem and keeping the phone awake.

However, disabling fast dormancy will just disable the FD-wakelocks itself, but you didnt get much more deep sleep time, cause the l2_hsic-wakelock will take over a huge amount of CPU time from the FD wakelock in case you still have a huge amount of background traffic.

Just get the point: If your apps create background traffic, your phone _must_ be awake to send/receive data. And if its not the FD-wakelock thats keeps your phone awake, it is the l2_hsic-wakelock that keeps the phone awake while transferring data.

If anyone wants to know my advise: Fast Dormancy is 2013 a mature energy saving feature and the samsung devs aren't stupid. So just keep the settings the phone is configured.

When disabling FD you eleminate the FD-wakelocks but in most cases you didn't save energy.

If you really want to save energy, configure your apps wise that they don't create much background traffic.
