Hey.
Is there a way to restrict gprs and other cell based data transfers IF open or accessible WiFi is available ?
I have all data (including Wifi) set to off, but as soon as i touch anything data related (weather update in this case) it happily turns on my DATA(cellular) even though i'm at home with my own Wifi floating about in the room.
I would prefer some sort inteligent priority manager over dumb forced data lockdown.
That doesnt mean i dont want to turn data off mnaually. Is there any means of reliably shutting off cellular data channels ?
I'm on recent Elite RC3 (flashed yesteday, rom and update).
I am still on stock AT&T ROM, and if keep wifi on and data off, then all data goes through wifi without switching on data.
But, I guess you are looking for a scenario when both wifi and data are switched off.
I saw several posts suggesting that leaving WiFi on where you have WiFi connection helps you to save the battery which I'm finding pretty strange. I thought WiFi actually drains battery faster then anything else. Are savings due to the fact that WiFi is more efficient then 3G or does it actually holds true that it saves battery?
All things being equal, Wi-Fi uses less power than 3G. Wi-Fi radio waves don't have to go as far, so they're easier to generate. When Wi-Fi is on, 3G is off, so you'll save power if you're actually transferring data.
A lot of programs will initiate data transfers by themselves when connected to Wi-Fi though, so perhaps that is why some will notice higher drain when Wi-Fi is on.
Also, if Wi-Fi is left on and you are on the move, your battery will drain since your phone is constantly searching for available networks.
Unless you've changed the settings, however, when your phone's screen it off it switches back to 3G to handle data.

Yes, as Scotty said above me...

This however, is untrue. At least for me. I run the leaked 2.2 and my WiFi is always on at home, my data connection is never active. I check this by dialing *3282# and hitting send.

When I have wifi switched on I lose around 5 to 10% an hour. With it off I lose 1 to 2%. I don't have anything set to sync differently via wifi. I only have a few apps that sync data and those are set to do so every 4 hours or so.
I have tried leaving it both on and off overnight to test this and every time I've left it off I woke up with a full battery. If I leave it on I have to charge again in the morning.
When I'm going out I turn wifi off so that my phone isn't constantly searching for signal.

In the Wi-Fi advanced settings (Hit Menu when in the normal wi-fi settings), there is a Wi-Fi Sleep Policy (which specifies when to switch from Wi-Fi to mobile data)
By default, my device was set to 'When screen turns off'. the other options were 'Never when plugged in' or 'Never', I switched mine to 'Never'. You should notice that when you turn your screen on, the wifi icon doesn't show up right away. Of course, I'm on 2.1, so this may be different in 2.2, but check it out.
For me, I get no cell signal in the building at work so I need to keep wifi on. If I turn it off my battery drains fast from the 3g radio constantly trying to lock on a signal.
It depends in the quality of your 3G connection, but all things equal I have seen that using WiFi instead of 3G does save battery, when the WiFi is connected of course. Anytime a radio is constantly searching for a signal or trying to hold a weak signal, power usage tends to go up.

Check out Y5 Battery Saver.
This app turns your wifi on/off based on the cell towers that you are on. You just connect to wifi, enable the app, and it remembers what cell towers you were on while you were in range of that wifi location. as soon as you are off of those towers, it turns off wifi. to add new wifi locations, just disable the app, connect to the hot spot, and re-enable the app.
This gives you the best of both worlds. you get to save battery while you are using wifi and when you are out of range it doesn't continually search for new wifi networks to connect to.

Whenever I turn my screen on, my wifi icon is right there. No delay in it showing up. I don't remember ever changing the sleep policy when I updated so I believe this is the default behavior for 2.2

+1 on Y5. There are a few other apps in the market that claim to do the same thing, but I think Y5 is by far the easiest to set up and works really well. Nice little utility so you don't have to keep remembering to turn off the wifi manually when you are out of range.
Now if I could just find a app that does the same for my bluetooth when it is near my car....but that I think is much harder to do without it actually polling.
Hello everyone;
I'm using a Moto G, with stock 4.4.2 Android. I don't have a data plan, so my carrier will charge me 1,20€ for 30 MB of mobile data traffic, should I use it. For this reason, and because I have wifi access at work and home, I keep mobile data off at all times.
Despite this, I have been charged twice, in three weeks, for mobile data, even though I have it turned off and wifi on at the time I'm being charged for it. Furthermore, the phone was idle on my desk when I was charged - I can tell because I got an SMS whenever I was charged for mobile data.
Has anyone experienced similar behavior? Is the 'off' switch trustworthy?
Thank you in advance
I'm just wondering if anyone else is running into this. Even though I've disabled most the apps the phone came with (including all the Verizon apps) even when I connect to wifi my LTE doesn't gray out. I'm really not sure what is keeping the data on I saw that visual voicemail and caller ID could be the problem but I've already disabled both. Should I be worried about this? Are you guys getting data grayed out when connected to wifi?
It stays on but it doesn't get used. There's a setting (I think it's called download booster or something similar) where you can use WiFi and Lte for big downloads but the default option is this is toggled off. I wouldn't worry about it. If it really bothers you, you can always manually toggle off data.

That most certainly is not true because my account is showing I've used at least 200 mb over the whole day even though I've been connected to WiFi all day. On my s5 the data symbol would gray out to show that it's not being used. But this is not graying out and I can see that's it's sending and receiving data. Going to data usage shows nothing. I know I could always turn off data but let's say someone sends me an mms I won't receive it until I turn data on again. Trivial but bothersome nonetheless. That's why I was wondering if people are actually having their data sign gray out because mine is not.
Remember, data reported to Verizon is always delayed. It's normal for it to show both, but when WiFi is on it doesn't use data unless you are downloading something using the download booster.
The data usage tab is correct, if it doesn't show data being used on mobile data then it's not. Check the WiFi tab and you should see it there.

I don't have download Booster enabled. Yes I know it is delayed. But this was the first day of my billing cycle and I had been on wifi all day at my house and it still showed that I used 214 mb of data. I used a data monitor app to see if both connections are pulling data and in fact it is. I made a video call on hangouts and it showed 240 mb used on wifi while 40 was used on Lte. If the data is lit up and you can see the arrows under it lighting up while you're on wifi your data plan is still being used. Don't say that when you turn wifi on your data is not being used that is wrong. If it dims then it's not being used.

If the arrows are showing data on mobile data then yes something is wrong. Check WiFi settings to make sure it's not set to stop using WiFi of the connection is poor.

Question's in the title.
Secondly, do you use it or not?
On Fi, so I try to keep to Wifi for the month (saves me $10 over if I even download an email by Fi). No problem with the battery - I can get more than a full day sometimes. Do we use "it"? Wifi? All the time. The only time I ever turned it off was back when I had unlimited data and would turn it off when I left home (automatically with Tasker).
I use Automagic to turn it (and Bluetooth) off when the screen is off and there's been no connection for more than 5 mins. It turns them on again when the screen wakes up. Not sure how much difference it makes to battery life though - the biggest difference is made by turning of WiFi (and Bluetooth) 'scanning' in the location settings ...
