Do any of the available ROMs have optimal power consumption when tethering compared to others? Is there any way to crank down the Wifi strength so that the range is shorter but the battery lasts longer?
Thanks

I'd like to know this too. It doesn't seem necessary to have serve wifi from a phone at full strength, since the usage are usually done within limited range.

or try this Small utility that allows you to adjust the transmitter power of WiFi, thus can be great help to save battery life. Has been done 5 hard dimmer. The apartment is missing 4 or 11 dBm for normal operation. Battery consumption with this sometimes falls on the 60-100 mA.

Interesting. Are any solutions available that work on LG based ROMs rather than CM7?

Okay it installs on my phone but it says "iwconfig: not found" using the LG ROM.

Developers help us with iwconf??
Yep, still looking for a solution...
Here is a ss..
any news on this? I also use stock rom and I wan't to control the wifi signal power.
Try this. (It is for stock 2.3.3 leak, not tested on 2.2.x). The settings are done in /system/etc/setwifi.sh, so you obviously need to make it run somehow on boot (like, via install-recovery.sh or whatever) or you are stuck with running it manually.
Flash from recovery (toggle signature verification first).
To test, just run this from terminal emulator (as root):
Code:
/system/xbin/iwconfig wlan0 txpower 16
(can replace the value with whatever you think will be best )
Just wanted to report, that flashable zip does seem to make WifiTxPower happier. I don't know if it's actually reducing the TX power but I'll find out next time I try tethering.
It really does seem to be working! Tethering to two devices with the screen off, at lowest power, it only used up 12% in the first hour.

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!
Ok first i llike to say i am in love with my dell streak 5 i have the froyo 2.2.2 build 347 OS stock firmware no root no nothing done to it and its unlocked i have had it for 2 months i like it very much, But it still has not replace my ipod touch for only one reason and one reason only, WIFI Range it seem that the dell streak cant pick up nearly as many Wifi access points as the ipod touch. It act's just like the ipod touch before i installed the app call wifi-fofum. Once i installed that app on my ipod touch wow it completely changed the Wifi Range.
My question is is there a way or an app or do i need to root my dell streak to access a superuser admin file to extend the Wifi Range i realy dont want end up selling my streak just because the Wifi antenna suck's.
There has to be a way just like jail breaking the ipod touch
Please direct me to the right thread or the right place Becuase if that is fixed it will be the perfect tablet/phone
TY gut's in advance
I'm not sure you could extend the range through just software. Have not heard of it. At the same time, my 3gs and Iphone 4 show about the same strength wifi as the streak.

You can generally control the power of the radio through software. So if there is a utility or setting for that, you can crank up the power at the expense of battery life.
wifi range
I haven't had any luck finding anything either....
When you flash Streakdroid, DJ Steve does have some commands scripted in I think that improve 3G signal stability, but as far as the firmware (upgrades for the antenna drivers) I don't know of anything that has been released.
I just flashed the 351 baseband a few days ago and I noticed better download speed, but signal strength is the same
There has to be a way
Do think that there is an app that does control the radio on the wifi antenna if there is please let me know i don't care for battery life
It's been made pretty clear, if there is ever a fix it WILL NOT be an app, an app is software.
The WiFi range issue is related to the firmware for the antenna, which in turn software has nothing to do with, it's a driver issue.
Maybe in the future one of the basebands will tend to it. For the moment I am using the 351 baseband, and although signal strength is the same, download speed is higher, more stable
I think i found a solution
I think i found a solution I know what you mean about it not being software related and basically being firmware related.
I think I have found a solution in order to increase radio frequency by basically editing the (build.propc) file in the phone the only thing is in the settings that are inside the file I'm at a loss to which settings to change I see all the settings in their but basically don't know what setting to change.
I know there is two ways to edit the file one would be using adb, but I think the easiest and best way to edit the file for me is using Root Explorer.
I realy dont care much for battery life so increasing Radio Power would realy help me and maybe some one else.
I found this thread that talks about the build.propc file and how he changed the setting to boost wifi/3g
http://forum.xda-developers.com/showthread.php?t=947134
If some one out there can find this of use in order to set a wifi/3g boost would be great help to all of us

will jd ultimate significantly improve my battery life,i'm a moderate user on a rooted razr
I used it for a while, and didn't find any significant modifications.
I did notice a significant difference when using JD Ultimate. However I had to stop using it because it interfered with my apps that sync in the background (Dropsync, etc).

What i did was I just went to stock.
I go back and forth. But I rooted and then
Bloat freeze and system app remover that could
help alot.
yeah it does work, helps to achieve the 12 hour battery life. read my thread on how to achieve it using juicedefender, just check threads started by me
It works well and I recommend it to everyone EXCEPT for whatsapp "whores" who needs a working connection every second.
What is does is simple. Basically, It turns off 3G connection, and turn it on every 15 mins. If you have an ongoing connection, like if you're downloading a file, it will not turn off its 3G connection until the download is over.
This will not affect phone calls and SMS.
For Ultimate, you can customise it turn 3G on more frequently during peak hours like checking every 5 min during 9 to 5 (working hrs), and set it to less frequently during sleep time.
I dont recommend jd ultimate, on rooted stock if your in an area with 4g lte and want to use it, it seems that it caused some strange issues booting down and up the radio, I used it on my og Droid with cm7 and it worked like a dream, so I'd guess it'd work better on an asop built ROM

Yeah, this ^
It DOES significantly improve battery life, but when you go to use something like a browser, there's a delay while the wifi or 3G/4G radio "wakes up". No free lunch.
Keep your GPS off when not in use, keep screen brightness at a reasonable level, use wifi over 3G/4G when possible, you'll improve battery life without the downsides.
I use it, better than smart actions for me, nicest thing it learns, and you can change it to your needs. Sometimes you do have to wait for radio's to reconnect, but it's seconds, and you can make it fit your needs, and it does save battery life, just depends how much you want it to control.

This is an accurate assessment of jd. I have ultimate and find that it does extent my battery life by several hours but you will notice a bit of lag with your data connection and inconsistency for apps with background sync. I turn it off when I know I'll be around a plug if needed.
19 hours yesterday!
i got 19 hours still had 30%battery life,normal activaties for me include fb,words with friends, speedtest,texting,even talked on phone for 20 minutes,jd ultimate really does work,you just have to play with it to get it right and remember not much will ever help if your screen is on a long time
Is there a way to disable 4G, so the phone uses 3G instead and uses less battery or even better 2G? It seems as if the option is not on the Amaze as it was on the G2.
I have speed rom 4.0 I think. Gonna put 6.5 on soon.
Also is there a way to make your battery last longer if you game alot or watch movies?
You can try buying an Anker Battery for your Amaze, I got one off eBay and it's a noticeable difference (nothing huge though)
You can try using an app called Widgetsoid to toggle your 4G/3G but I'm not 100% sure it'll work with every ROM out there so give it a try

4G is 3G. 4G is just a marketing term. It's just a faster 3G network.
You can switch to 2G in the Mobile Network Menu.
Turn off your data, lower brightness, turn off Bluetooth, GPS. There are a lot of things you can do to save battery.

turn down the screen brightness, undervolt, use a better Kernel / use a powersaving governor (throttle down the frequency quickly when not needed)

Well "faster 3g" might be picking up more battery than "regular 3g". I have Simple Mobile, so their "SIMPLE 3g speed" is not exactly the fastest. Seems like "fast EDGE" speed to me.
My brightness always goes up by itself even when I turn it down for some odd reason. I have my data and wifi off when I don't use it. I rarely use GPS and bluetooth, so most of the time they are off. I don't use that JuiceDefender crap cuz it doesn't do much. Doesn't it slow down your phone?
I can't find the 2G in Mobile Network Menu (which is why I said I’ve seen it in G2 or it might’ve been MyTouch 3G Slide. I'm using SPEEDROM 4.0.)

I don’t know the good settings to undervolt. I’m scared about screwing up my CPU. You can choose kernels to use?! I didn’t know that (I thought a ROM had a specific kernel requirement), but wouldn’t WiFi be broken or something.

all of them should have no problems with wifi or anything (well, some have "beta" versions that might not have wifi working). each of them implements different things to help give you performance or battery or undervolting etc... try each of them and see...
If you can't find it in the settings you can do the following...
Open your Dialer ( yes, like you're going to call someone)
Dial *#*#4636#*#* then pick Phone Info. Scroll Down and find Something that says "GSM Auto (PRL)" click on it. Now you can change that to "GSM only" and you will have just 2G speeds. It will save battery life if that what youre after.

It will set it to 2g while screen off, and turn 3g on after screen on or unlock.. so if you have weaker signal it will absolutely increase battery life, but 2g uses less battery anyways.. there is about 2-3 seconds after screen on before it switches back to 3g(4g, whatever). I've been using it for days, I am happy.

2g<wifi<3g<4g for battery drain, or at least that's what i've found from my side, with 2 g taking up the least battery, and 3g/4g taking up the most.

On the Droid Razr (and infact any Android device) wifi uses MUCH less power and resources than HSDPA/3G+ services. The reason being that the gain needed on the radios part to receive a packet via wifi is (generally) much less than over a cellular connection, due to the quality of the signal being much higher. It hasn't got to work as hard to get a good set of packets to work with. Your phone will be working like a mad thing trying to buffer a YouTube video on HSDPA - dealing with massive packet loss and syphoning the 'good' data from the 'bad' data - whereas on wifi with much less packet loss and a higher rate of that 'good' data being received, it can relax a little.
My advice on battery life - download a data "toggle" widget and place it on an unused home screen. Whenever you are not using any mobile data services turn it off using this widget. Leave wifi on only when at home/a location where you know you will be able to use it. Turn it off when you go out. When you want to use mobile data when wifi is not available, just toggle it on. I get 3+ days of always-on use using this method.

It could well be. Or if you have applications that are configured to only sync/update when on wifi, this will naturally put your phone to more use than if say you only used 3G/HSDPA for checking email.

When you say you have compared them with 3G , it means the phone's data sync causing this problem is out of question. As in both cases ( wifi and 3G) the phone would connect to data based on the set intervals.
Possible cause: if you have multiple wifi sources near your devices and you have granted them access, here your phone constantly tries to connect to the best available wifi . If this is true , just use wifi managers available on Play store or remove access to unwanted wifi routers/access points.
