So I got a text message from Sprint less than 10 min ago saying I could save battery life by turning ON WiFi is this true?Anyone else received this?

ive seen this somewhere else though im not sure how valid it is because not only is it searching for wifi, apps are still using your 3g/4g. though i could be wrong on that.

Yes, Sprint's been pushing wi-fi for some time now. It's all over the online account section of the website. No reason to be concerned.

Wifi uses the least power as long as you're actually connected to an access point. If you're not, the wifi radio only wakes up for about 15 seconds every few minutes to scan for networks it's previously been connected to. This is assuming you have wifi set to always stay on (default behavior) instead of turning off while the display is off.
I've hit 3 days on a single charge if I kept the phone on wifi and worked from home. Personally, I leave wifi on, but have Tasker set to disable it when it connects to my car stereo over bluetooth (and re-enable as soon as the stereo disconnects). No point having it on when I'm driving, but I have that setup so that it disconnects from my home router when I get in the car, forcing it to connect to 3G so I can start streaming music.

Of course they're pushing it, it saves them money if you use wifi for data. While it does save you battery if you use wifi and have a steady wifi connection I wouldn't put much merit in anything any company pushes.

I really don't think Sprint cares about our batteries ... just trying to minimize our data usage on their network.

In the new OTA leaked ROM base, v3.28.651.6, this seems to be happening to many people, including myself.
<DC CONNECT> IO error: msg='/127.0.01:7771 - Connection refused
This happens after turing 4G on and then turning it off. You can see this error in logcat. and it repeats endlessly!
Does anyone know why or have a solution to this?
It has also been reported HERE.
4G works fine, it doesn't break 4G, it's just some stupid looping error.
its not just the new rom, it happened on 2.1 and 2.2 ota's.
It has been concluded that this is normal behavior, since the early builds. Apparently, that's how wimax works on the evo

That's pretty lame coding on HTC's part then. Why have something that is turned of try to reconnect infinitely to something. That has to waste resources.
It happened to me yesterday but when I rebooted I could connect and stay on 4g. Weird.
In regards to the effect of this on battery life

9pm - 4g Turned on, then off.
9-~12: screen always on, multiple reboots (4g turned on/off after each reboot)
~12pm - screen off the rest of the night (while in the error state)
The results to me look like any other day under the same usage conditions. To me, at most this is an annoyance when trying to logcat for something unrelated, but doesn't seem to affect battery like people have been posting in multiple forums.

I agree, I am at work for 14 hours a day and I come home with 35-40% battery left. Prior to this new leaked OTA ROM base, I came home with 5-10%. I use the same phone the same way, so regardless of this weird arror, battery life is still good.
Like the guy in the post that you linked to on the Sprint forum says, seems to go away if you Turn off 4G and then completely power down (Hold power button, and choose Power Off). A reboot doesn't fix it, has to be complete power down.
Agreed, it's a silly leftover, I usually just use some sort of a tail-like application, and just filter those out if i need to do logcat.
It's the 4G radio that causes major battery drain, not the repeated log messages anyway
What is the most efficient way of accomplishing this? I am on Slim ICS, and even if you set the sleep policy to "Never," I'm sick of waiting 15 minutes for the radio to turn off. It's actually terribly draining on the battery.
Any ideas?
WiFi really shouldn't drain that much. I find it drains much less than 3G

you can find the GreenPower on google play, it offers you to turn off wifi, 3g and manage many things else to save your battery

In theory, you're right. But in this pic, you can clearly see a steeper slope when WiFi is active. This is with about 1:40 of display time and rather light usage

to me it looks like the sharpest decline is when you don't have a mobile connection

I'm also using Slim and under Settings > ASS (Advanced Slim Settings) > Power Saver there's a section under Advanced Settings called Screen-off Wi-Fi action that you can change to turn of wifi when you're screen is off. Make sure you also check the toggle "enable power saver" at the top of the power saver menu.
Having said that, I find that leaving wifi on all the time extends my battery because I don't have very strong cell phone service at my house and it's easier for my phone to check for email or google voice texts and only have to reach my router which has good service rather than strain to reach the cell phone tower.
If that doesn't work you could use Tasker or Setting Profiles. I find SP to be more user friendly.

Anybody else having trouble with the WiFi not turning back on after waking from sleep? I'm using the "Only when plugged in" option for "Keep Wi-Fi on during sleep" to conserve power.
What I'm seeing is when I am connected to a WiFi network and then lock the phone long enough for the WiFi to turn off, the WiFi will say it's on in the settings menu but won't show any available networks even if I hit "Scan". The only way to reestablish the connection is to toggle the WiFi on and off.
I've disabled Smart Actions because I thought that was interfering but it didn't help. I've also booted into Safe mode with the same problem.
My router is a Linksys WRT54GS. The settings are: SSID broadcasting, WPA2 Personal (AES), G-only.
I've attached before lock and after wake screenshots to show what I'm seeing.

I kind of see the same thing. Wi-Fi works fine until I leave the range of the router (e.g.leave the house to go to the store). Upon my return I see the same thing your screen shot shows. Turning off wi-fi and turning it back on solves the problem No other phone I've ever owned has ever done this.
I've tried auto connect, leave it on and off during sleep, reset the router and nothing has had any effect.
So it's not just me. I wonder if this is present on all phones or if we just got a bad batch.
EDIT: Well... for some odd reason the WiFi came back on from a sleep just now. I don't remember changing anything other than installing the 4.2 camera and changing the build.prop to a Galaxy Nexus. I shall investigate further.
EDIT 2: Could this perhaps be an ICS issue? (I came from a DROID X with GB) I ask because a GSIII in our house seems to be doing the same thing.
Not sure. My GS III will connect automatically without fail. I just got home with the Razr Maxx HD and had to go through the off and on routine to make it connect. I had the GS III last evening and it reconnected as usual once I got home.
There's an extensive thread on the Moto support forum where everyone is complaining about the wifi signal dropping randomly when connected. You are the only other person I've seen with our issue.
I haven't played with the GSIII extensively so it might have been a fluke that it did that.
I did see that thread but the Motorola support site has been loading very slowly on my end so I haven't been able to look through the whole thing due to my impatience with it.
Something's definitely wrong with the site. There's a thread for that as well LOL.
Okay guys, at least for now I've been able to get unlimited tethering via USB. This does require a paid version of FoxFi for PDA net. I'm unsure to whether or not the wireless tether works through FoxFi, currently sitting at 6.5/7 GB for the month so I haven't been able to test otherwise yet.
As usual with T-Mobile, you need to create a new APN and use IPv4. Then on FoxFi use USB tethering. On the PC client, be sure that you use the Level 1 Hide Tether Usage option in settings.
Build.prop was set for:
net.tethering.noprovisioning=true
It's extremely worth noting that I've done this on my ROOTED phone, with all T-Mobile apps removed except Mobile Hotspot, Device Unlock and visual voicemail.
My Account, money, TV, Lookout Security and com.t-mobile.pr.adapt and basically any other T-Mobile app is gone.
Please see screenshots for any other settings. Furthermore I'm not responsible if you mess anything up or if it doesn't work for you. Just sharing what I was successful with so far.
If I'm able to determine and wireless option I will post here as well, but must wait until my billing cycle reset. I've got an idea, but as this phone is brand new to me and just had a new baby on the 9th, it's been difficult to find the time to say the least.
Good Luck!

Sorry, 21st. As long as I do USB only I have no issues. Last night, I used WiFi Tether router to stream a few things through my roku 4, it hasn't seemed to increase my hotspot data, so that may be an option.

Is there a way to enable WiFi tether? With the unlimited tether?
I can't seem to share my WiFi capability through USB.... I do IT Work and is a vital function when reception is spotty....
Is there a option I missed or need to enable?

I did the same thing and my data jumped
I bought my S7 less than a week ago and I notice something odd happening with my mobile data connection.
When I'm using 3G (Mobilcom-debitel_Vodafone/Germany), my connection is consistently laggy. Every action that I require connection for takes a couple of seconds to be executed, if executed at all. For instance, click to download an image/audio/video/etc in whatsapp, it takes 5+ sec to start the download; open the browser, takes 5+ sec to load the page; open Deezer, takes 5+ sec to start loading the data... and so on. I notice this problem since the first time I used 3G on the phone. Everything is up-to-date and I installed the phone from scratch, app by app, no backup/transfer from other phone. On my previous S6 I didn't have this problem.
Some information that might be useful:
- I use 3G/2G (auto-connect), no LTE/3G/2G
- I'm usually with BT/Wifi/3G enabled at the same time, not necessarily connected to a device or network
- The data icon keeps the up arrow on, but the down arrow off until I actually receive data and the request is processed
- If I try to turn off the mobile data connection/put in airplane mode, it takes the same amount of time for the connection icon to disappear (5+ seconds)
Is it a known issue? Anyone with the same problem?

Just checking: you know that the phone is brand new, 2 days old, right? Just checking... Also, since the first time I went outside to use 3G I noticed the problem.
Did you have this Problem by using WiFi only?
2nd Option is run a Speedtest (Ookla) to Check the ping.

I did it already and there are no problems there, as you can see below. 3G speed on my plan is limited to 21mbps.

On a side note, I did a reset of the network settings and apparently it got better. I'm still testing it, can't say yet it's fixed, but I noted some improvement for sure.

As I posted, resetting network settings was apparently a solution, but this morning it was clear that something was still pretty odd.
I will consider starting from scratch. I'm so lazy, it takes a long while to config the whole phone again, but apparently it's worth a try.
