This may be a dumb question but is there a way to set up wifi and data to automatically toggle? As in, when wifi is available it uses wifi, but when its not it automatically switches to 3g/4g? When im home i like to use wifi, but then when I leave I lose it and usually forget to switch over to data, so I get no emails or updates on anything until I look at my phone.
Option 1: Leave wifi and data on all the time.
When a trusted wifi network is available and your phone is connected, your phone will not use data (you will see the data indicator automatically disappear even though it is enabled). When you are no longer connected to wifi, your phone will automatically bring the data connection back.
Exception: using apps (usually Verizon-specific) that require a mobile data connection will bring the 3g/4g radio out of dormancy.
Pro: automatic switching, no need for additional apps.
Con: leaving wifi on takes its toll on battery life.
Option 2: Download/Install Llama from the Market
After you teach the program what cell towers are where, you can define criterion (ie you physically leave or enter a defined area, a certain time, etc) to carry out specific actions, including changing volume, display brightness, toggling data connection, wifi connection, bluetooth, gps, etc.
Pro: automatic switching of most anything imaginable, saves battery life compared to leaving wifi on
Con: additional app running in background, occasional instances of bugs

wi-fi matic is the app you want, it auto toggles wifi on when you are on the same cell tower than is near your home, as soon as your cellular switches to your home cell towers it toggles wifi on, and when it's away from home cell towers it toggles wifi off, you can use it for multiple wifi networks as well, i travel for work so i dont have a work wifi but u could have it auto toggle on at work or home, its also extremely easy to use, far easier than any tasker program.

Hey guys,
As the radio stack is the second cause of battery draining after the display, I was thinking about a way to save battery life by reducing the impact of the 3G connection. Most of the energy saving apps on the market are only disconnecting the phone from the APN, but this isn't a great solution as each app could be set to update at different times and thus being unable to download data even if the user sets some exceptions. So I thought that an application which operates in the following way could be great to save power:
- The phone uses the 3G network while the screen is on;
- It switches to 2G when phone is in standby mode;
- It disconnects the APN data connection while the phone is using a WiFi Network;
Obviously to avoid possible issues during the switch between 2G and 3G the following rules are applied:
- If there's an incoming call or a phone call is being performed, there won't be any radio switch until the phone call is ended;
- If there's an incoming SMS/MMS, there won't be any radio switch until the text message is fully received.
Unfortunately as I'm not a Java developer I can't code anything like this. But let me know what you guys think about my idea and if it's technically feasible... Maybe some developer could be interested into further exploring my thoughts and will try to create such an app
Cheers
I'm not a developer but I think it sounds like a great idea. I go into settings and switch it to 2g when I'm in spotty areas outside of town. I have to work a bit to keep my N1 battery alive all day...
Hello I'm new here.
I don't know if your suggested profiles are the best case scenarios. You would need to calculate your data throughput, not just the radio power.
If you need to send 100 packets, your radio would be on the longest for edge > 3g > wifi. So, even though wifi uses the most power, it would be for a much shorter duration.
A profile for "place calls only" would work somewhat like airplane mode, but still keep track of towers. Your phone just wouldn't register on the network unless you wanted to place a call. You would miss your incoming calls, have no data connection, or sms. But, you could have it check at an interval for voicemail or sms. This would be most useful for "ringer off" situations like class or meeting.
Afaik Android is always connected to the APN even if the phone is not downloading anything, consuming a lot of battery power. On other platforms, i.e. Windows Mobile, the connection can be terminated by user and re-established when an app needs that.
The amount of data downloaded by widgets, Google mobile applications or apps which operates in background like eBuddy or Facebook should be quite low, so downloading the required data by using GSM or WCDMA while the phone is in standby would be pretty much the same. The only difference is that downloading stuff using GSM/EDGE should take much less energy power.
So that's why I thought about the app I described before: the phone can save a lot of energy power while in standby and be back to its full horsepower when there is any kind of user intervention. Pretty much the same thing that the system already does for CPU usage. It scales to the less consuming protocol (or, in the case of CPU, frequency and voltage) to save power
I know on the google api it isn't possible to do this, but I don't think that isn't the problem.
At the moment you have 3 options. GSM only, WCDMA only and GSM/WCDMA. Whenever you switch between the 3 of them, the phone will lose signal for 10 seconds before it can find the best network. So the switcher here is not the best as you will lose connection, and what if you are downloading something at the same time...
What you need is when the phone is on GSM/WCDMA that it knows the best network to pick from depending on the phones lifecycle. GSM/WCDMA loses battery power because it always tries to find the best network to connect to, so for example if you are on GSM it will constantly try to find a 3G network etc (as far as I understand it).
What we need is the ability for the phone to stay on GSM when the phone is idle and then when the phone is woken up to automatically start to search for a WCDMA network and then gracefully switch over like it does now. For this I have no idea if it is possible as I don't know how the scanning of the network works. If it is possible then that would be wicked. But this is what we need.
my preference would be if the phone would stay on 3g as long as any possible even if there would be a more reliable 2g connection and only switch to 2g if there really is no way to connect to 3g. turn of apn if the screen us turned of for longer then 1 or 2 minutes and only check every 15 minutes or so.
most of the time I'm on 3g only mode . since I live in a city I got good coverage almost all over the city. only problem is that when there is no 3g available also my phone is unreachable. I don't really miss data connectivity when there is no 3g since 2g is so slow that I rather have no internet at all but not being sale to be called or texted is a major disadvantage...

I have the Wifi enabled on my Droid Charge so when I'm home it will use the Wifi. But when using the Wifi the 'mobile data' icon is still highlighted in the pull down tasks..
now is it trying to use BOTH the wifi AND the mobile data at the same time? I want to use ONLY wifi at home to help conserve battery usage.
then when I leave my house will it automatically turn wifi OFF and use only mobile data?
trying to keep the battery usuage as efficient as possible.
In theory thats how it's supposed to work.
hahahha in theory.. but does it actually do it?
and another thing.. in the Mobile Networks Settings.. under 'System Selection'.. you can choose either LTE Automatic or CDMA Mode... being I am ONLY in a 3g area and do NOT have 4g LTE in my area yet.. should I choose the setting for 'CDMA Mode' Will that save the battery? or does the phone try to switch from 4g to 3g...
Yes, that is how it works. If wifi is on, the phone will use wifi by default, regardless of what it is connected to for mobile data (4g, 3g, 1x). Check out http://myresolver.info from your browser to see your ip and dns server you're using.
I know this is a stupid question, and I'm actually embarrassed that it's my first.. but, does 4G get turned off automatically when I connect to a WiFi network? I know it maintains a connection to the data network for other services, but what about 4G specifically?
I think I answered my own question.. In the Phone Status info page the "mobile network state" DOES toggle between connected/disconnected based on my wifi status.
Not fully, or servcies such as mms would not work. However you can enable this to happen through Juice Defender, and possibly other applications as well. I fully disable network data with wifi connected through juice defender, only drawback I see is unable to send/rec mms untill you disable wifi, allowing the network connection to estblish itself again.
edit: This is only for the data network portion, voice services can and will still carry over the 4g conenction which is just enhanced 3g
Does it go to a state that uses less power than the "usual" network mode? I'm looking for ways to conserve power while maintaining full functionality. Using Llama and JuiceDefender right now also.
Juice Defender can disable the data portion of the network which saves battery when connected with wifi. In the on the "About" screen in Juice Defender scroll down, there will be an option that says "disable on wifi" under which you can select to disable the network data
T-mobile S7 edge.
This doesn't always happens, but it happens often enough that it's beginning to get frustrating. When I'm connected to WiFi for long periods of time (at work/home), then leave to an area that has full LTE coverage, the s7 edge will not connect. I get the signal bars, they're usually always full, but no '4G LTE' logo. If I open any app/browser, it claims it's not connected to the interwebz. If I put it into airplane mode, then come back out, it'll grab full 4G LTE again and work fine.
Not sure if I have some settings screwed up or if i'm overlooking something... or maybe it's just a bug.

I am trying to find a free toggle widget to do one simple thing - enable or disable the WiFi Calling feature on my T-Mobile HTC One M7.
Why? I've been having shoddy internet connection issues at home for the last year. Spikes, timeouts, and packet loss before it even gets TO the routing server. How this affects my phone is obvious when you also consider I can barely get 2 bars of 2G signal while inside my home. The best way around this is to turn WiFi Calling on and set it to "WiFi Only" mode so it doesn't try to turn the cell radio back on while the connection is unstable (never more than 3-4 seconds). Just means I have a few seconds here and there where it may drop a call or delay a text or something, which is a small price to pay if you ask me.
However, I can't do WiFi calling outside of the house, which means going in and disabling it every time I want to go somewhere. After a couple months of this (because WiFi calling doesn't disable when WiFi is off for some reason...), I'm trying to find an easier solution. Losing 20% of my battery overnight from having it swapping back and forth is a pain, so I'm not going to set it to "WiFi Preferred", which started all of this.
I tried the application at this thread but it only seems to want to work with Tasker, which is a paid app and currently not a financial option for me (that same $3 is two days' worth of food).
Maybe you need to look into "Mobile Data Toggle" widgets? Accompanied with wi-fi toggle widget, you can set Mobile data to Off, and wi-fi - On when you're at home, and vice-versa when you're away.

Mobile Data is always off 'cause I have a minimal 50MB plan. I have a WiFi toggle on my power bar (wifi, bluetooth, gps, brightness, etc). I need a WiFi CALLING toggle.
