Fast Dormancy - T-Mobile LG V10 Q&A, Help & Troubleshooting

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..

To ROOT or NOT to Root, that is the question.

Coming from the DX, the benefits of rooting (even with it locked down) were WIFI tethering, screenshots, and overall just being able to customize the phone more with themes, colors, etc.
From what I can tell, the Wifi tethering app just can't hang with the native MobileHotSpot tethering option provided by the phone, in which case, it becomes less of a benefit.
I can see why people don't like Sense but it doesn't bother me one bit so that really isn't a factor. Just wondering what other features (or lack thereof) are pushing people one way or the other.
well i supposed it's up to you if you like to tinker or not. so far i am using the das bamf rom and really like it. for one, all the vzw bloat is gone, and there are a number of nice little features such as the battery charging icon, 5 icon wide app drawer, transparent app drawer/notifications.
root enables programs such as set cpu to control the cpu speed. for instance, i have the cpu slow way down when the screen is off saving battery.
if you are happy with your phone the way it is, leave it. if you like to play around, try new things, and have a better phone than the manufacturer came out with, root it. there is practically no danger and you can also go back to stock.
I just rooted because I hate all the bull**** bloatware. Also like to customize
The ability to remove the Verizon software off the phone (VVM, VZ Navigation, VZW Backup, etc) and the ability to change the DPI to something more usable (i.e., less big).
Those are my reasons...
Titanium Backup... Removal of bloatware... Those two things, even if you plan on keeping stock rom, is enough reason to root, in my opinion.

Are you referring to having to scroll through them when in the apps folder or actually feeling a performance difference by removing them? If it's scrolling past them, that doesn't much bother me..
Now that the kernel source is out, I'll definitely be rooting. Battery life is a top priority so undervolting is a big factor for me if nothing else.

who needs vz backup assistant when google does it for free? i guess some people can live with trialware taking up useless space but cityid is just awful. I use to get nag screens on my incredible. There is an option to remove it if you cancel the trail peroid, but it is still there taking up memory
My reasons that I rooted:
1. Get rid of bloatware
2. Get rid of bloatware
3. Customization options
4. *FULL* backups of my phone (Titanium Backup)
5. Overclocking, Underclocking, Overvolting and Undervolting
The Kernel was just released by HTC today, so we will be getting some really nice mods for the T-Bolt soon. Some of the things I want:
1. When my phone is plugged into a charger, I want it overvolted and overclocked for FULL performance (1.6ghz stable please )
2. When my phone is on battery, I want it back to 1ghz, but lets unvervolt it to get better battery.
3. When my phone's screen is locked lets underclock it down to 250mhz, seriously undervolt it, and get some real juice out of it.
4. When my phone's screen is locked, auto disable 4g, gps and wifi for even more battery savings.
Basically I want a phone that screams when it is supposed to scream, and tidy on the battery when it is supposed to be.
For me its about bloatware and speed. Plus (correct me if im wrong) the hotspot tethering is only free for a period of time, so eventually youll want that root for the tether.
I always equate it to if you buy a pc versus building it. Most people if they buy it the first thing they do is delete all the crap for overall performance.
Even if you root only to get rid of the bloatware your going to see an increase in battery life (especially from crappy blockbuster) and load speeds.

also read reports of blockbuster running in the background constantly updating and draining the battery unless you physically go in there and turn it off...i didnt bother checking that out, i promptly removed it for good
For me it was all about the customization. Everything I own I tweak to make it just to my like so the same goes for my phone, so rooting was just necessary. Also a lot of the custom ROMS are designed to help improve battery life, and since the battery life of the TB isn't very stellar to begin with, it is nice to be able to increase it by flashing the correct ROM. I really don't see a situation where you wouldn't want to root it.
My moto is when in doubt... Root.
It just makes it better
Had my Thunderbolt since day one. It's my first smartphone. I want to root it and in the process of doing so. I've read that it will wipe my phone. Just curious. Does that include my SD card as well? and how would i go about flashing my stock ROM just in case i need to take it in for warranty purposes?

Coming from the DX you were in a walled garden (not as bad as another walled garden, but walled none the less). While I do like Sense, there are also Cyanogen, Liquid Metal, and MIUI as examples of rom styles that will completely transform your phone.
MIUI menus for example are by far the best designed that I have seen. And you might reply who cares about menus, but once you have messed with it, it makes a world of difference.
Cyanogen adds a crap ton of function then tends to focus on stability. This lead to (IMHO) the smoothest most stable rom on the Droid Inc.
Liquid Metal is just way outside the box. I was not fond of it (except the kick ass lock screen), but I bet someone here who did fancy it could speak for its merits.
The real question is, why the hell wouldn't you root

I will most likely root, I guess I have just been pretty impressed with this phone stock, wasn't sure I needed it. Take into consideration more customization, tethering and increased battery life, again, I think it's a no-brainer.
Are you guys seeing an increase in speed and battery life now that you've rooted? I know killing bloatware also kills running services which should in theory help, but isn't undervolting the best way to maximize juice?

Coming from a turtle phone, this is very easy to get used to as-is..

Dissapointed in SGS2

Well after the WOW effect wore off my phone, i am starting to HATE the flaws.
I bought this phone outright for a hefty $600 and hoping i did not waste my money switching over from blackberry.
MY problems
Bluetooth disconnects every 15 minutes, plus sounds like garbage, i did some reading on this and its a common problem yet appears to not be addressed yet? i am using a Jawbone Icon by the way and its dual connected to my work BB
Data(HSPDA) randomly disconnects at least once every 2 days and requires me to pull the battery to get it back going.
Battery drain is beyond crazy, i cant get 5 hours out of the phone with moderate use.
This thing heats up like crazy!!!
I know the last two things are software related, and people say upgrade to KG2, well my phone had 2.3.3 and KG2 and this is what it shipped with, so what should i go to?
Or can i just solve all of these issue by rooting the phone? if so, i will go that route.
Thanks.
Dustin
if you want to go that way(rooting,FLashing Roms)
Think twice, the SGS2 has a binary counter that counts how many times you flashed unofficial software on the phone,
if you brick it or something happens, screen breaks etc, you might ran into some problems @ samsung if they check the counter
you can reset it yourself by buying a JIG, google it!
I've had no issues with my bluetooth headset (logitech freepluse). i'd guess it doesnt like being dual connected
I've had no issues with losing my data connection (i did on galaxy s though). how strong is your signal before you lose it?
as for the battery drain, make sure you're exiting your apps + all the usual other stuff (turn off sync, wifi, bt, set to autobrightness). 2.3.3 does have the drainage issue for some people. i'm on villainrom 2.3.4 and have no drainage issues
rooting won't help you out.
HSDPA disconnects? if you have H always on that means you are either downloading or uploading something most of the time, H only turns on when there is data being pulled or sent, you should see the 3G icon MOST of the time, if you are streaming music/video then you'll see the H kicking in.
I have a Jawbone Cruiser and have no issues whatsoever I have 2 devices paired to it but only 1 at a time, A2DP works flawless and it even sounds better than the original Galaxy S.

Warm but not overhot .

KH3 latest stock firmware on this forum .
Or can i just solve all of these issue by rooting the phone? if so, i will go that route.
Rooting has nothing to do with battery problems all it does if give user a lower level access to the OS .
Hundreds of battery problem posts with tips methods etc but for me the starter has to be ,
better battery stats .

Rooting will not solve these issues, but I can maybe enable you to start solving it.
However, before you start messing with kernels and firmwares I would really try to find out if some of the problems might be hardware related or not. If so, you could use your warranty to get a new one or get it fixed. Once you start messing with custom software you're never sure if they will grant you the warranty or not.

not sure where you get that from? i actually hate apple and take that post as quite an insult, one and only thing i ever owned from them was a ipod way back, and it got stolen 2 mths after i bought it and i never replaced it.
that aside, i came from a Blackberry Curve 8330, although it sucked, it did have good bluetooth connectivity,decent battery life, and did not heat up, keep in mind it was a CDMA phone.
so i know i have some changes to expect with a new network, but it appears lots of these have been fixed by people and i am just trying to understand the software and device, KG2 KY this,etc is all new to me, so i have been reading lots but find it confusing since its so vast.
needless to say it will be kind of disappointing if i cant connect 2 devices to my jawbone icon at the same time and work flawless, as this is huge for me.
Also i NEVER see 3G data show up on my phone, its always the H with up and down arrows, should i see 3G? im up in Canada(Saskatchewan to be exact)
It appears i should update from KG2, yet KIES shows no update, i have not dove into Odin to try that out, maybe i should?
Any help is greatly appreciated.
Thanks.

lool! some of these guys on here are too funny. ok how the f*** are u only getting 5 hours? i get 14-16hrs moderate use . i really would suggest rooting your phone. it really helps! i mean with the overheating problem i have under volted and under clocked my cpu and my phone doesnt heat up no more! woooop! lol. funny that my 3g and bluetooth is perfectly fine. oh and rooting is very very easy now and odin is quality and... simple . as im typing this im flashing another rom, lol. flashaholic . its a really good phone and ive had many many phones.
so now i have mixed reviews? should i root or not.
i really just want to solve my issues!

Rooting doesn't solve anything, just gives you access to hidden files. You need to flash a newer rom(kh3 or kh5) and hope it fixes those issues.
I agree with the above poster, I've been using android since inception and I don't believe in rooting a phone to mask the issues you are having, upgrade the software, there are many roms to choose from, get the device running well before you think about rooting.
People are giving new android users the impression that rooting is the answer for phone issues, it is not.
Rooting is for advanced users who want the extra access to explore the power of android.

I don't understand why everyone seems to be pushing the USB JIG, it's like there are people making and selling them here or something.
@BrokenPixel, H or H+ doesn't drop to 3G as fast, if your Telco doesn't support Fast Dormancy, or you have Fast Dormancy disabled.
I like Blackberries, it is lacking as a end-user smartphone, however for companies, I still like the privacy with point to point encryption. Android does not have that unless you purchase a 3rd party application which means both parties have to have it as well. Again, it really depends on what you are using the phone for. I still recommend using the right tools for the right job.
@Gustopher, calling Blackberries a "second cousin of a minor demon..." is like calling a screwdriver the bane of our existence, or a hammer "the killer of thumbs..."
peachpuff is correct, instead of rooting your phone, perhaps you should try changing the modem to something else instead, try KH3, KG6, KF4, KE4. Perhaps in the mentioned order. It really covers most regions, since we don't know where you are at!

Thank you for actually being informative.
I am in Canada by the way(Saskatchewan) and i am running on the Sasktel network(Bell essentially)
I always thought i had to root in order to install something different then KG2?
i am not sure what my network supports, but i have NEVER seen 3g since the day i bought it.
i have turned off some of the recommended things to save battery life, it seems to be helping, we will see what i get
If your problems are related to your settings, flashing newer firmware (KG5 for example, works fine with me) will only really help if you do a complete wipe/factory reset. See the guides for that.
That would be done best by rooting with CF-root, going into CWM-recovery, doing a backup there, do all "wipes", reboot straight into download mode and flash the fresh firmware via Odin. The guides are all there.
Just make sure to play with some settings like gsm/wcdma in your network settings first.

Have you never heard of BB's? He came from a Curve..basically a glorified pager. He could probably go 3 days on that thing with a single charge. Kind of like going from a Commodore 64 to a high end laptop.
One thing I haven't heard mentioned about rooting is the fact with root you can install Titanium Backup..and with the Pro version..freeze apps (instead of deleting) which allows you to fiddle with perhaps some rogue apps that are draining your battery.
As usual with most Androids..make sure you don't have FB or Twitter syncing crazily (and if you're running multiple tweet or FB programs..be sure they aren't syncing as well). I'm not familiar with Touchwiz..but if they have their own "social networking" apps that you don't use (and you use the actual apps themselves instead) be sure to check those and make sure they arent sync'ing either (and better yet freeze them with TiBu).

Default Fast Dormancy Setting ATT GS2

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.
Sent from my unf#cked att sgs2
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.

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...

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... :-/

[Q] Battery after rooting - is it better? (BW Removed)

Hi, I have an Amaze...have been 2 days but the battery is not promising really good.
I know there are application fromm T-mobile which are really eating a lot of power...anyone did a comparison before and after rooting??
(PS: I assume you removed the majority of the T-mobile apps)
If I decide I can live with this phone I will root it and try by myself! I am a bit upset with the battery life.

I can't say anything about rooting as I haven't done it yet. Check out the posts on the seidio battery in the accessory category though. It's a discussion about other batteries. I, personally, have had great results from the 1900mAh seidio battery from Best Buy.
Actually the battery is very bad, as suck as my sensation. I think it doesn't change a lot after rooted

All rooting does is give you root access like access to system partitions, etc. It doesn't affect battery life in the slightest, and anyone who says differently doesn't know what they're talking about. I also have not noticed any preinstalled apps eating battery, either.
I know rooting does not affect battery...I believed many people were supposed to remove all the T-mobile bloatware. By default, there are too many applications running and I wanted to know if that was giving a small or a big jump in battery life. On my MyTouch 3g (ok..old generation) only My Account from T-Mobile was eating a lot of battery...so I removed it.
I have followed the Seidio battery post...I probably will buy that one in case I feel I can't live as it is. My biggest hope was to root and use Llama or Juice Defender to make the phone in 2G while is in stand by...but I don't like these solutions.

Will be I able to get more battery life if I root?

So basically the title says all. I'm planning to use this device a little bit longer, and the only problem with it is the battery life - but I love everything else, like the display, the sound, the design. I was a wonder to root before few months but feels like at this point, at least with Samsung you losing more than you will gain with root. Like Samsung Pass, Samsung Health and Security folder. I know there is a way to recreate them but not sure is worth it all the work. Although, I tihnk is worth it to sacrifice those (but I really will miss Samsung pass), to have a better battery life.
So my question is, if I root my device, put some custom rom + some app like Greenify, will be I able to have a better battery life than now? At the moment I make around 3h of sot, which maybe is normal for device +1 year old. But I can't trust it when I'm going out. Always need to carry a power bank with me, just in case...

yes, installing a custom ROM will likely increase your battery life so as that the kernel that the ROM youve chosen is optimized for efficiency. If the ROM you choose is overclocked beast-mode gaming champion settings enabled, then no. Some ROMs are also very stripped down eliminating seldom used apks thereby increasing batt life as well. What model do you have? if its the g965u, you aint rootin it fwiw
Thanks for the response!
Yes, I understand boosting or using some modes for performance can lead to worst battery life. My device is G965F. As for now, I'm planning to wait for the final version of Android 10. Then I guess would wait for developers to update their ROMs and chose the lite one?

Youre most welcome!
If you do that, you might be waiting for a while as Samsung has been recently pushing to make root more and more difficult. If youre dead set on rooting, id do it now and avoid the pitfalls of being on a bootloader version that you cant go back to your old one from and waiting for the devs to figure out the new source code etc etc.
