Default Fast Dormancy Setting ATT GS2 - AT&T Samsung Galaxy S II SGH-I777

I have the international version which defaults to "enabled." I was curious what the AT&T network engineers set their version at as I am on AT&T's.
This works on the international version and hopefully it does on AT&Ts
1: Dial *#9900#
You will have the option on the screen to enable/disable the setting.
There is much debate on the international forum on the impact of this setting to data speeds/battery life on different carriers.
Thanks in advance!

My option is to enable. So I am assuming that it's disabled.

Yup, seems disabled by default. I believe AT&T's network doesn't support FD.

from what I understand that the Apple's IOS 4.2 has built in FD that prolong the life of the battery on AT&T's network.
Engaget Article on IOS 4.2 and FD
To avoid this, AT&T researchers (again in collaboration with the University of Michigan colleagues) are proposing Tail Optimization Protocol (TOP), which implements fast dormancy using a simple interface that coordinates among currently running apps before demoting the device.

But as to WHICH type of fast dormancy the phone support is beyond my knowledge

I will try to do some testing and report back to see with it on and off and how it affects my data speeds and battery life and will try to report back...

I'm running checkrom, dd 2/7, and kj1 modem and mine was enabled by default.

I get the following when I try that #
"Connection problem or invalid MMI code"

It seems like changing it in that menu does nothing - however, whether it is enabled or disabled by default may matter. Hellraised I9100 firmwares seem to almost always provide better battery performance with the UCKH7 modem than I777 firmwares, and FD might be part of the reason why.
UCKK6 modem had power consumption issues for me. Drain at my desk (weak signal) was higher for the UCKK6 modem than UCKH7 running on a device with a permanent wakelock held! (A bit under 1%/hour for UCKH7 normal operation, around 1.2%/hour for UCKH7 modem + wakelock and for UCKK6 + no wakelock) All of these are on XWKL1 system base running recent Daily Driver kernel releases.

Are you using a 3rd party dialer like go dialer? The codes only work on the stock dialer.

Thanks, that would be the problem then.

latest uNnamed and DD 0207 is off by default.

Since this was really never answered, I too am wondering if fast dormancy should be enabled or disabled. When asking in regards to shishir's rom if fast dormancy was enabled he said, "Yes it is! And it's supported as long as you're on AT&T." However, LiLRom's 1.3.1 changelog states "Fixed Fast Dormancy build.prop since AT&T doesn't use this."
Now I've googled and haven't found any concrete answers as to whether AT&T even supports FD...

You need to use *#*#9900#*#*. I too had the same issue like you did until I noticed in another forum someone asked to try *#*#9900#*#* and it worked!

Epic job digging this one up.

I can confirm on my wifes SG2 bought from ATT the Fast Dormancy is DISABLED.
I just DISABLED it on my unlocked international SG2.

Mine was enabled by default. Then again that could be a product of the custom rom. Never checked when I was stock. Either way, my battery life has been exponentially greater since root and custom rom

It's better to resurrect an old thread that already discusses this topic than it is to create a whole new one. XDA rule #1: "search before posting". If a thread already exists that deals with what you want, DO NOT create a new one.
And to the recent poster:
I'm not sure anyone has done "scientific" testing to see whether or not "fast dormancy" helps. Based on the available generic GSM literature on the matter, it would seem like a good idea. Faster data call spin-ups, and less battery use. However, AT&T notoriously doesn't follow the GSM spec fully, and often times picks and chooses what to deploy on their network.
I suppose the best way to test is to run a whole bunch of speed tests with and without FD turned on. And to live a week with it on, then a week with it off, and compare average battery life. And if you can get another 15-20 people to do the same, then we do some statistical analysis on the results, you might actually find out whether to enable it or not.
Short of that, the rest is heresay and wildly subjective opinions. Any given individual's usage patterns may vary so wildly, that without looking on aggregate (and with correct analysis), it's almost impossible to tell whether or not specific "insert-preference-here" actually has a positive effect or not. It is worth mentioning that fast dormancy does appear to be disabled by default on AT&T based ROMs for the GS2. Of course, such a setting might have been over-looked, or possibly even disabled despite potentially helping performance/battery on our phones. Who knows. Unless you have a friend who works as a network engineer at AT&T, we might ultimately never get an answer on this... :-/

Does anyone know how to disable Fast Dormancy on the S3? My carrier does not support it.

I'm puzzled by the behavior of the data connection on my phone (network is 3 UK)
When the connection is busy, it goes to H+ as expected, and when idle it reverts to H. So I am assuming that "Fast Dormancy" is working.
But from my understanding of fast dormancy, I was expecting it to revert all the way down to 3G instead of H.
Very occasionally, when idle it goes down to 3G momentarily then right back up to H where it stays as long as it remains idle.
Can anyone explain this to me ?

That usually means your phone was transferred to another cell or antenna on the same cell. It will then have to re-negotiate the low-level stuff.
Just to stress it out to anyone wandering by: Keep Fastdormancy ENABLED UNDER ALL CONDITIONS unless your provider does not support it or you actually know what you are doing.
Disabling fastdormancy forces you to fall back to 2G whenever you don't need the speed since it will otherwise drain your battery very quickly.
Thanks for taking the time to explain the details d4fseeker.
I had read an explanation of fast dormancy, but didn't fully appreciate the implication of some of the fine details.

Is that a normal behavior or a bad one?

Bug in stock firmware?

Can anybody confirm this, please?
We have two S3 phones, and we have same issue with both of them.
If you enable power saving option, you cannot see email which is composed in HTML (stock e-mail client). Account is hooked to MS Exchange, but I thing that's not important here.
If you disable power saving, everything works.
android version: 4.0.4
Kernel: 3.0.15-671647-user
Build number: IMM76D.I9300XXALF2
More than likely not a bug but a power saving feature you should only be using power save mode when you really need to save power, don't expect the phone to work properly when you have it enabled.

hm, How it that helping than if making my device unusable? That have no sense. I can live with only one core, 600 Mhz, low light etc, but I want it to work as expected. It's like you have a car that would not open door if low on fuel?
I can't see any real power savings.
If your phone sleeps, the pegasusq scheduler will go down to 200MHz (or 100 with Siyah) and disable 3 of the 4 cores, if the horsepower is needed it ramps up the clock speed and hotplugs the other cores again.
So in fact all power saving does is reduce your maximum available power, luminosity, ... If you take care not to have apps such as Skype running in the background 24/7 you should be fine anyway.
Most of the drain comes from 3G anyway where power saving cannot do anything. There are other methods to "fix" (bypass) the 3G drain
It's all ok, but does your phones behave the same way? That was the original question. This is obviously a bug and need to be reported. I just need some confirmations.

[Q] Which Modem/RIL/ROM combination is most stable for travelling?

I will be traveling soon. I have the JellyBean leak by izap on my phone right now... The battery life is somewhat ok, but I have network issues with it sometimes. People can't get to me even when my phone shows full signal strength. Therefore, I would like to know if there is a Modem/Ril/Rom combination that features stability and is most suitable for making and receiving calls internationally. It would also be good if the combination isn't a battery sucker while searching for network while not in range.(Because this seems to be an issue with many people :-/ )
While traveling these are my top requirements from the GS2:
Stability- no SoD or incompatibility with networks abroad.
Battery life- no battery drain while it isn't being used
GPS- quick locks in remote areas (I already seem to have a solution for this; but haven't tested it yet)
Camera- no pink spot or noise (Could you also recommend a good camera firmware for Fujitsu M5MOLS that fixes FPS issues and pink spot? -I've tried solution in every Camera issue thread I could find on the forum, but I still get pink spot)
Thanks! I'm looking forward to your replies! :fingers-crossed:
Just in case this question isn't in compliance with the forum rules, then I'll be sorry and the Mods can move it/delete it.
If it were me Id just go back to Samsungs proper stock rom/modem.Then when I come back,Id change it back to what I liked.

To be honest your expectations are too high.Your wanting what everyone on here wants,and it doesnt exist.This is why were all tinkering with roms.
In some of requirements,while one thing improves,another will diminish i.e battery life.
I currently use rooted GB stock,stripped down with all the crap removed.I used to use nelp3 modem(gave best signal),but according to callers,speech was choppy.
I'm on NeatRom Lite 4.0 (JB leak), and see in better battery stats that "No or unknown signal" is 99.3%, and I have been in areas with good reception all day, so something is not right with the LS6 modem here in Norway. And I'm not sure if there is any other modem/ril for JB leak?
As for stability and battery time, CM9 stable worked great for me, so maybe have a look at that? With litle use, batterydrain where less than 10% pr 24hour on stock battery...

You can use other modems for Leaked jb but not other rils.
Leave ther ril alone and change the modem. Read through the thread for information how to change modems.
Will it not make phone reception worse if ril is not matched to modem?

@jj_95nano You should probably have a look at the modems for the region you are travelling (2 first letters), but as that thread has not been updated since summer, I don't know if theire recommended modems are still valid...
You could also maybe check the signal strength of your provider on where your going.
I went on holiday recently where the tmobile reception was crap,and vodafone was a lot better.

Just flashed the latest stock ICS 4.0.4 for my region... There are many bugs and FCs... I wanna flash GB, but the GB for my region is infamous for its battery drain. I guess I'll keep CWM Backups of different ROMs and try them out when I'm on the go. :-/
Depends where your going ^^
If I was taking my S2 over seas, I'd get a sim card for that region (could prob get one prior to travel), leave a redirect to no. on my voicemail. Then I would get a cwm flashable modem for the region & install it on the plane to destination. Rom wise, MIUI gb/ics - would be your best bet... everything works out of the box. Stay away from JB, unless you have a laptop handy, then it wouldn't really matter

[Q] Anyone else get a rude welcome from msm_hsic_host?

Hey folks,
New guy here, just picked up a new LG Optimus G on AT&T yesterday afternoon to replace my aging Samsung GS2. This was a somewhat quickly made decision (for me anyway) so I haven't done as much research on the LGOG as I typically do before purchasing a new device...it's quite possible I missed something stupid. If so, flame away...
As of right now, I'm stock/unrooted, with a small number of primary use apps installed. While screwing around getting familiar with the device yesterday, I noticed a high level of msm_hsic_host wakelocks, with an apparently related but smaller amount of suspend_backoff wakelocks in Better Battery Stats. CPUSpy indicated approximately 25% deep sleep for the run, which was about10 hours from purchase to going to bed - with a partial charge in the middle.
This concerned me slightly, so I let the device charge overnight, then unplugged this morning and let her go on a screen-off draindown test. Did a 50 minute run, which resulted in zero battery drain (still at 100% for a few moments when I lit the screen up at the end of the run) but ZERO deep sleep. The vast majority of the run was spent at 384 MHz, with small amounts at 1512. This run was done while on an ATT microcell for calls and WiFi on for data (set to stay on with screen off). Background data was on. While I am quite impressed that I'm seeing 1-2% drain per hour with no deep sleep, I have to believe this is not how the device is supposed to operate.
Prior to buying the LGOG, while looking at the forums here, I noted that Jank4AU was here - a name I recognized from the Aria and SGS2 forums. He provided an excellent overview of the device (via PM - Thanks Jank4AU) and mentioned the need for rooting to disable fast dormancy, which apparently AT&T, in their infinite wisdom, left enabled by default, to improve battery life. My limited experience with chasing wakelocks indicates that HSIC is likely radio related. Is this msm_hsic_host wakelock triggered by the fast dormancy system? My searches have turned up little to indicate either a yes or a no...
forum search turns up this (partially related??): http://forum.xda-developers.com/showthread.php?t=2144927&highlight=msm+hsic+host
Google search turns up a bit more, but very Nexus 4 focused (I realize they are similar devices -- possibly similar fixes??):
https://productforums.google.com/forum/?fromgroups=#!topic/mobile/jO65dcM7J2Y[1-25-false]
On the sprint version (wifi related for us too? WiFi off drain test is next for me I think.): http://forum.xda-developers.com/showthread.php?t=2106529
It looks like Thracemerin is chasing it in kernel development for 4.2.2: http://forum.xda-developers.com/showthread.php?t=2102986 Is this less of an issue on JB than on the stock ICS for our devices?
At any rate, I'm still digging though the ROM threads, but will likely be rooted and maybe off stock by the end of the day today. I'm looking forward to spending some time with the LGOG community, and hopefully I'll be able to contribute meaningfully at some point!
Sorry for the great wall o' text...

In the process of trying to tack this down, I froze a bunch of apps, turned off a bunch of background syncing type stuff, re-enabled FD, and I've had wifi off the past 2 days, and now the wakelock is still the highest on the list, but it's usually < 10% now instead of 44%, and my deep sleep percentage has reversed, from 25% to 75% now. Re-disabling FD doesn't seem to have made any difference. Is FD only relevant for LTE? I only have 4G here.
Yeah, there's a fast-dormancy toggle app in the themes and apps section. It will greatly reduce your wake-locks.

Sweet. I'm missing Google Now an awful lot...I'm thinking a switch to the SnowJB ROM might be in order...appears that has "built-in" fast dormancy "fix" - I assume this means it's disabled by default on that ROM.
Got revert to stock all set up on my PC, so now I get to go root. This will be the soonest after purcahse I've rooted a new device (previous quickest was 4 days for the SGS2). Thank you all for the warm and helpful welcome to the LGOG device forums!
Edit: just out of curiosity, what do you guys typically see for deep sleep percentages? On the SGS2 85% or so was about my average on ICS with my full complement of apps and background data running. That dropped to 75-80% with Google Now running in the background.

The zv9 zvb root works on 11c.
I am seeing the opposite of some of the others in a way.... I can't say that disabling FD hurt me and I can't say that enabling it helped me. All I can say for sure is in my case it doesn't seem to make any difference one way or another.
Also, the FD toggle app doesn't require root. Not that you shouldn't root, just that you don't need to in order to try this.

LOL, Thanks adfurgerson (another i777 convert iirc?). By the time I got back to read this I was already rooted and unlocked via the guide sticky procedure! Went without a hitch.

Yes I had I777, so far this is a good group here. Seen you found irc channel. If you can do without camera and GPS cfx is nice.

Yeah...I might be able to live without one or the other (GPS is easier to get along without for me) but without both, it's not quite to daily driver status for me. I thought I saw some comments from the dev that kernel work towards getting the camera going is almost ready. At that point I might give it a shot.
Edit: OK, first dumb question of my time here (won't be the last): Is there a key combo to get into recovery? Google pointed me to either vol-/power or vol+/home/power. Neither of these worked for me, all I can seem to get with keys is fastboot. Had to ADB into recovery to make my backup...gonna flash SnowJB once that's done.

I believe that I put up an ICS version of Google Now in my inverted apps thread if you aren't ready for JB yet. Also, in that same thread, there is probably still a copy of Google Now (not inverted) for ICS as posted by XsMagical. If you can't find it, PM me and I'll send the file to you.

Thanks, appreciated. Just got SnowJB flashed (glad to be rid of that damn carrier id in the notification bar, since it says ATT Microcell at home and takes up most of the notification bar!). If I run into issues, I'll jump back and take a look at your ICS GNow...

Good deal, that SnowJB is pretty smooth.
Itnis hidden menu for recovery, volume up and power for bootloader then volume up twice then power. Quickboot app also works.

Gotcha...thanks. I have quickboot now, so all good. knowing that combo is nice in case I get in a pinch sometime though and am working from stock without ADB available (hopefully that never happens ). Is that button combo/hidden menu stuff posted somewhere? If so I missed it. Might be a good thing to add to one of the "read me first" kinda stickies (assuming it's not already there and I missed it)...
Edit: And first short duration drain test after root/unlock/SnowJB1.1 is giving me 68% deep sleep - with GNow enabled and full complement of apps (a bunch more apps than previous test).
Edit 2: Initial 3 hour test after SnowJB install - 5% total battery drain over 3 hours, including 20 minutes screen on for browsing. 70.4% deep sleep, with minimal (1min 30sec) running at max CPU. I'm used to seeing 5% drain just from that much screen on time, so this is excellent performance in my book!
Oddly enough,my phone was kept awake by msm_hsic_host wakelock for over 7 hours last night. I'm abroad at the moment, with my phone in airplane mode all the time, wifi was turned off during that time, and the fast dormancy toggle was doing its thing. Weird. I'll see if it happens again tonight.

Fast Dormancy

Dial 277634#*#
Since T-Mobile supports this data-voice feature, you can enable it.
Since OP didn't say what Fast Dormancy is or why you would want to use it, here's an explanation:
https://en.wikipedia.org/wiki/Fast_Dormancy
After reading the explanation my question is :
It sounds like a good thing that would help extend battery life so why wouldn't it be enabled by default? That is to say, what is the downside that we are being "protected" from by the carriers decision to ship the phones with this disabled by default?
Is there a negative to using this?

Through limited research I wasn't able to determine if T-Mobile USA fully supports fast dormancy - changed it anyway and started to get additional wakelocks and worse battery life.......go figure. Not really interested enough to pursue any further, changed it back to where it was - battery life "normal" - wakelocks gone. If they do support it, not sure why it defaults to off
I called Tmo a few months ago and they told me they do not supporr it, but other users say they do..
