Ok, so I do not have internet at my house so my phone is my primary internet source via Wired Tether 1.4. Normally I can stay connected to data(3G) for about 30 to 45 minutes and then it will just shut off. Then when it shuts off I just pull down the notification bar and put it in airplane mode for a second or two then data restarts fine. I use my data heavyish if you want to say. (Youtube, XDA, Facebook, email and everything else you normally do) My signal is a solid 2 bars. I have tried *228 opt 1&2 and also swapping radios. Did not seem to help. Could be signal but just not to sure considering I can DL around 1mb/s
If it makes a difference I'm using Shed's 2.0 GSB w/2.42.01.04.27 radio and conaps unreleased kernel which generaly I keep oc'd at 729
It isn't a giant issue, its just kinda annoying.
Also I've attached the speedtest.net results for proof of speed.

I have a lot of experience with tethering as it was my only home internet for about six months until several weeks ago, finally (thank the lords of cobol - ugh, did I say that).
I have tried just about every snake oil imaginable to get tethering to work better, including switching back and forth from wifi to wired tethering. Sometimes it seemed for a while that one (usually WIFI) would work better than the other, but that would only last so long, too.
The longest I hardly ever had a problem with it continuously connected was actually about a week straight if I remember correctly. That was the best I ever had. The worse was disconnects every few minutes, or just as soon as I continued interrupted downloads after re-tethering.
My favorite and most common snake oil was using an app called APN OnOff to reset the APN to default. For practical purposes, it probably effectively did the same thing as you using Airplane mode, which I thought I had tried but I didn't think it worked as well for me, or even at all. Even after using APN OnOff, most of the time I had to reboot as well.
I had tried one without the other and it seemed like it required both for my tethering to work "reliably" again. I use that term loosely, of course.
I was using over 30GB per month data at my highest tethering use, and it was probably only that "low" because of the frustration and difficulty in depending on it.
I download A LOT so it really sucked at times, but it was better than dial up...sometimes.
I will say that one definite improvement was using Cyanogen Mod (v6.x and above) based ROMs which have support for built in WIFI tethering widget and using apps off the internet to use CM's built in wired tethering as well. These are implemented differently than the "old" Wired and Wireless tethering for root apps.
I highly recommend you explore them. One major difference, for me (and I tethered to two computers, my own and my girlfriends) was just how fast even the wired tethering would connect to the computer once I started it, versus wired tethering for root. Wireless tethering also turned on and off and actually connected much faster.
If you've never wireless tethered before, in my experience if you're going to depend on it at home constantly like I did, I kept it plugged in constantly anyway because it used a LOT of battery, and I also took the battery cover out (besides taking the Eris out of my body glove case I use) and kept a fan blowing on it to keep it's temperature down.
If you do decide to try this way, like I said, CM6.x+ includes "notification power widgets", which are widgets built into the pull down notification bar. They include a WIFI tethering widget but for some reason not a wired one. There is an app on the market called "Tethering Widget", though, which has both single widgets and widgets for both functions, in case you decide to try it's tethering ability.
Edit: I'm half asleep so forgive me for not paying attention that you're already on a CM7 ROM just like me, much less that I know you've been active in the GSB thread recently.
Lol sleep is a must for most if us. Idk, like I said its not that big a deal. Its just rather annoying. Expecially when trying to download junk. I'm familiar with wireless tether for root and my thoughts are that is a useful app when "out and about". But for home use I don't prefer it at all do to the heat and it seems that over a session of use it looses its speed. Almost as if its idling down. That is majorly why I prefer wired tether. Cool battery and it maintains speed. Idk. I guess it could also be some code somewhere that prevents extended periods of use OR it could be just the limitations of the phones hardware. Might have to run logcat and see if I can get anything to come up on the disconnect. Can wt and lg be ran at the same time? Guess we'll see.

What's lg? If you're talking about two different methods of tethering, no. You can have as many ways of tethering installed at the same time, but you'll only be able to actually use one of the ways at a time. Let me know if you try Gingerbread/CM7's native tethering instead of the "for root" apps and if it treats you any better, as it did me in general.

I hope you have luck finding out something useful!
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.

Rooting has nothing to do with battery problems all it does if give user a lower level access to the OS .

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).

hey guys ive been really really trying really super hard to figure out why my android os is always at 80-90 percent cuz after 10 hours my battery is almost dead (in the red) so i got os monitor, cpu spy, and betterbatterystats to try to hunt the prob down and i have spent countless days since i got the phone to figure out what it is thats draining my battery so im on stock with codeworks kernal for cwm and rooted with superoneclick i froze a lot of apps and what not but still had the prob so i left my house one day to hit the beach and i said well i dont need wifi or gps so i turned it off for the 1st time and at the end of the day when i get home and pull out my phone from my bag it said it was on for 10 hours and i was only at 80 percent!!!! so i tested it some more and it seems that my android os is not high at all when wifi and gps are off plus i get awsome battery so my guess would be wifi drain i just want other ppl to try it also and see if that fixes there probs too idk just thought i would share my story sorry its so long but plz dont bash me if ive said noob stuff thx
Ya because when I'm right next to my router which is awesome I don't even get full signal so I think its the wifi.signal.

You should always turn off WiFi and Bluetooth when not connected to something. WiFi has been a thorn in my side too. I don't use it very often, and sometimes when I use it at home I forget to turn it off.
One of the things I miss most from my WinMo phone was the constant LED and notification indication WiFi is on. With Android and iOS if you are not connected you don't have any icon showing its on. There should be a WiFi with an X, like when you have no signal, to indicate: Hey you! Yeah, you ... you left WiFi on, you dope! Or, an option built into the OS that will let you turn it off automatically when disconnected for so long. I know there are apps to do this (juice defender is a popular one), but this such a core common sense thing that should be built in. At least with Bluetooth you see the logo staring at you when you leave it on.
Sorry to rant, that's been bugging me for 3 years.
GPS on the other hand only activates and uses battery when needed. However all sort of apps can call the need. Again, this warns you when its in use, so its not a surprise later.
I get much batter battery life than with my captivate, but I keep on top of WiFi and BT when not using them.

For wifi you can just set the policy to When screen turns off.
So far, not a single person has been able to actually find a wifi bug.
Every time someone thinks they've found it, things have been working as intended.
If you have an app that causes lots of network traffic, it'll inhibit deep sleep, but since most of the time spent handling the network traffic is in excessive suspending/resuming, Android OS gets the blame and not the responsible app.

I'm surprised that turning off wifi didn't make things worse, unless in your case the app responsible behaves differently when on a cellular network, or you have packet data disabled.
BetterBatteryStats is almost useless for hunting Android OS drain, as it does not show kernel wakelocks. The only way to get the truth is to get the contents of /proc/wakelocks
thank you entropy for that info but yes im stuck at the fact that even on mobile network it dont drain like it does with wifi which im not a pro or anything but im just assuming that it cant be an app cuz if it was i would think it would use the same amount of data whether it was wifi or mobile cuz internet is internet but for me i dont know about other ppl everytime i turn off wifi my battery dramatically increases by alot and my android os is never the highest anymore when its off so i dont know if this will do anything but i will do a factory reset and try my testing again like that and see what happens.... plz correct me if i say anything wrong im just trying to help but i only know so much im not a dev lol

I agree on Bluetooth. I disagree on wifi - Even for background data, wifi is FAR more efficient than cellular data in terms of power usage. There is no longer any reason to turn off wifi, unless you have a misbehaving app that consumes lare amounts of data when on wifi.
Unlike previous devices, the standby drain of the BCM4330 chipset in our phones is EXTREMELY low.
If Samsung's power_profile.xml numbers are correct, the wifi standby drain current of the BCM4330 on the Galaxy S2 is less than 1/10 that of the chipset used in the I9000/Captivate.
However, radio data is far less power efficient than it was on the I9000/Captivate - A change in the architecture of our phone's radio interface means that any radio data transfers, even for a single packet, incur a minimum 6 second wakelock penalty. (Compare to an average of 1 second for small wifi packets.) This doesn't even count the power penalties involved in transmitting to the tower vs. transmitting to a wifi access point.
In fact, when taking these two things together (high wakelock penalties for radio data, and wifi standby drain 1/10 that of previous devices), you should actually not only avoid turning off wifi, you should set the sleep policy to "never" so that it prefers wifi to the cell radio.

You are incorrect. Some apps specifically check whether they are on wifi or on cellular data and change their behavior accordingly. "Internet is Internet" is not true - cell data is fundamentally slower and more expensive in nearly all situations, and as a result, many apps behave differently on wifi.
For example, normally Google Talk will not allow video chat on cellular data, only on wifi, unless it has been hacked to change that behavior.
Some apps specifically have "use this feature only when on wifi" checkboxes, such as Amazon MP3.
I am 90% certain you have such an app somewhere driving data transfers.
Turn on wifi, reproduce the drain, and pull /proc/wakelocks as documented in the threads I linked above.
There has, to this day, not been a single documented case of the wifi chipset just randomly "wigging out" and keeping the device out of deep sleep - in EVERY single case, root cause was eventually traced back to network traffic, which could then be traced to an app. (For example, Skype in AndreLux's case.)
You might also want to install something like My Data Manager to see what is generating your network traffic.
When I first got my GS2, I was getting rapid battery drain and high heat. Turns out, I had put a SD card in that used to be in my old phone, and Google+ was uploading all the old pictures and videos that were on the card. My Data Manager showed me that this had used almost 800M of mobile data.
My data manager will show you what your usage is on mobile and on wifi, and which specific apps are using how much.

For example, normally Google Talk will not allow video chat on cellular data, only on wifi, unless it has been hacked to change that behavior.
Some apps specifically have "use this feature only when on wifi" checkboxes, such as Amazon MP3.
I am 90% certain you have such an app somewhere driving data transfers.
Turn on wifi, reproduce the drain, and pull /proc/wakelocks as documented in the threads I linked above.
There has, to this day, not been a single documented case of the wifi chipset just randomly "wigging out" and keeping the device out of deep sleep - in EVERY single case, root cause was eventually traced back to network traffic, which could then be traced to an app. (For example, Skype in AndreLux's case.)

thank you im learning every day because of ppl like you who like to share information like that i would love to reproduce the drain and pull the wakelocks but honestly i have no idea how to and i havent really searched for it either but i think i might just have to learn how to use adb and what not hopefully i can find out what app is draining my battery and causing android os to be super super high thx
I gave the ADB commands necessary for pulling the wakelocks file in one of the threads I linked on the first page.
For getting ADB set up, if you're on Windows you may want to look for Droid Explorer (Google it) - it's a pretty nifty frontend to ADB and I believe it helps you install ADB.

The name of it is "My Data Manager." It's in the market.
It's not mine, I just use it.
Okay..u guys should try out a app called "WIFI STATUS". It gives u a notification when your wifi is on but not connected. Really a awesome app.

On but not connected shouldn't be a problem for our devices - see my previous posts about the fact that our standby drain is supposedly VERY low.
On but transferring lots of background data when connected will go killtacular on your battery.
hi.
Since I do not have any data plan, I pretty much depend on open W-Fi network to get a connection, which are often far away so I get a poor signal.
I have noticed my phone can't handle a poor Wi-Fi connection as good as an iPhone / iPod can. When I place my phone and my friend's iPhone close to each other and connect both of them to the same, distant network, the iPhone would get a slow but stable connection while my phone would frequently lose connection to the router. My phone also would not connect to some distant network at all while the iPhone can connect to them.
Is there any way to make the Wi-Fi work better? Maybe some hardware fix similar to the GPS hardware fix, or perhaps some system files I can change so the phone would not "give up" so fast if the network connection is poor?
Thanks a lot.
ICS glitch does include pmfast mode which may increase wifi
Only. Things I can think of..

Very creative solution although I use the Wi-Fi only when theres no one around to talk with, for example when I am at a bus stop or during a (very) boring class.
I was wondering if there was any way to increase the power of the radio to get better signal? Or any other way to get better signal. I spend most of my time at home here in my basement and I get very poor signal down here, most of the time I get 1 bar or no signal at all. I was wondering what tips and tricks people used to increase their signal, and if there was any way I can do this in the software of the phone itself. I have my phone plugged in down here so increased battery drain is not really an issue.
It would be really awesome if there was some type of change that I could throw into a Tasker profile and activate with an NFC sticker so I can just scan the sticker and boost my signal! (Also, I'm on a Verizon S3)
Maybe I'm dreaming, but it would be really awesome if some way to boost my signal like this existed!
Thanks so much!
Buy one of those verizon signal booster units? Wait for an updated radio that can do more with less?
Or use your home wifi and a voip calling solution

You can try one of the many free network signal booster apps in the play store.

Yes, I think you are dreaming.
You might explore hardware signal boosters sold by Wilson Electronics. The basic configuration is an exterior antenna, an internal antenna and a two-way amplifier in between. Not free, though.
If you have WiFi, another option is getting whaterver Verizon calls their femtocell. It basically is a mini-tower inside your home, and your WiFi provides the backhaul.

I think those "booster" apps are scams at best. They probably just toggle your phone's settings to provide a placebo effect.
If you check their permissions, which invariably include "full Internet access" and a variety of privileges to explore local stuff on the phone, it's pretty obvious that the real intent is to rape your phone's privacy and upload the data to sleazy marketers, hackers, or worse. Do you really want to provide your phone connection log and location to some stranger?

Tip: get a job.
Trick: move out of your moms basement.
That should solve your problem... If not let me know and we'll try something else.. :thumbup:

Wow. That's rude and not helpful.
Chances are he hasn't even finished college yet or is still in high school. Or his office could be in his basement in his own house. There are so many other reasons he could be in his basement most of the time... He never even said he lives in the basement, just is there a lot...
OP - I'm not sure if there's any way you can boost the signal using software. If there was, I'm sure those enhancements would have already been implemented. If you have internet at home, you can buy a device from your carrier (every carrier calls it something different) that uses your internet as "cell tower".
Another solution would be to use google voice + groove IP so all your text messages and calls are routed through WiFi instead of the carrier.

Completely worthless.
OP sounds to me like you need WIFI calling. I'm not sure if there are apps in the play store with a similar feature as T-Mo's wifi calling, but it sounds more clear than when I use the cell towers.

I don't think that is very nice. Clearly this phone has issues with single and there was nothing wrong with their question. We're a community and we should be as respectful as possible to one another.

True, but it was funny. Lots of comedy is rude. Ask any of these guys. http://en.wikipedia.org/wiki/Insult_comedy
but seriously, I wish there was some setting that would improve the radio. I'd trade 1/2 my battery life for better signal. That would still leave me with an all day charge.

The comments above include a link to a similar product from Verizon, which the OP said he uses. Not very fast, though. It doesn't even support EVDO (3G) data speeds. And LTE service is out of the question.

so after i saw this thread, i called up tmobile to get a cel-fi booster for my dad, those asshole have the audacity to tell me to get my dad wireless internet so he could make phone call via wi-fi calling...damn that got me steam as hell. its not like i got him a cheap plan either, 10gb of data, freaking 1000 min... that should be enough for them to kiss my ass.

Excellent! Just for fun I went looking up Foghorn Leghorn quotes. Wow, they're much funnier and make more sense now then when I was 7.
The unfortunate thing is Samsung has very weak radios. I know they have improved through out the years. But they still have have to work on improving their RF. I lose signal on my S3 in bad reception areas, whereas on my BlackBerry 9900 I still get HSPA.
