I have my wifi sleep policy set to turn off when the screens off, but I'm also streaming music with Grooveshark. Does that mean that Grooveshark is switching to mobile data when the screen is off or is android smart enough / Grooveshark programmed to keep the wifi on while it's running? Thanks.

If you have the hardware settings set to go off then they at most Likely going off and swapping to cell data
Setting it to never sleep seems to help battery for me. It keeps the 3g radio off for background data syncing.

I had an idea how to save power.
How it works is that it would run in the background of the phone.
By default WiFi is turned off, however when an app requires some form of data connection, the WiFi app recognises this and turns on the WiFi.
If a WiFi network is near and you already have the password stored in the phone it connects to the network.
If a WiFi network is near and you dont have the password stored it prompts you with a popup. If you cancel the popup, WiFi gets turned off.
This way power can be saved so WiFi doesn't have to always be on and only gets turned on when needed.
Possible? What you think?
Juicedefender does this. It will cut off your WIFI if it's not around known networks. I think you have to buy ultimatejuice (it's worth it).
Hi guys,
I am new to amdroid platform. I've been using symbian before this. I want to know as to how do I auto use wifi when. Available without manually turning it on. Below is a use case scenario.
I have configured wifi as well as gprs. I have turned off background sync so as to conserve battery and the wifi is off. Now when my active sync want to connect to server to synchronize emails, it should auto check if I have a nearby wifi already configured. If yes, then turn on the wifi, sync the data and close the connection thereby disconnecting from wlan. If a known wlan network is not available, use the data plan of my service provider to get the job done.
Now I know for sure that when I've wifi turned off, the phone is not always connected to 3G. It uses it only if requested by an application. But when I turn ON wifi, it always remains connected to the known network. I want to avoid this for saving battery.
Please let me know if there is an app for that. I am using HTC DESIRE Z running Froyo (non rooted). I dont mind rooting the phone for this thing but only if a standard way is not available.
Thanks in advance,
Karan

I think Juice Defender does exactly what you're looking for.
Or Tasker if you really want to customize and make it location-based.
Good luck, and welcome to Android! I also came from Symbian.
Technically the phone can't know if there is wifi available unless wifi is on..
However, a tool like Tasker can use various contexts in order to determine if Wifi is to be turned on. For example you could use cell tower ID's to determine if you're at a certain (fairly wide area) location, like "at work". Or you could use GPS to get more fine tuned information, however it doesn't necessarily work indoors.
Or Tasker could also turn on Wifi if ActiveSync is running, assuming it's a distinct program it can detect.
I see in the time I opened the thread and responded someone else suggested Tasker as well. It's several bucks but it's well worth it, it does a LOT.
You should try an app called "Y5".
JuiceDefender does this for me. It must use gps positioning to determine if you are in an area that you have as a familiar wireless network. When I am home my wifi turns on and connects automatically. When I leave it shuts it off. JuiceDefender is great for many reasons beyond this.

GPS uses tons more battery power than just leaving WiFi on would. It might be using cell tower triangulation for a rough area, but I doubt it. The most efficient way to detect if familiar wireless is near, is to turn the WiFi on for a minute or so and do a scan.

WiFi doesn't use power to maintain the connection until it's needed, or something wakes it and it realizes its no longer connected. 3G uses power to track cell tower connectivity and stay connected, but it is very little. WiFi only uses more power when you're in an unfamiliar location, since it actively scans for new wireless networks.
Hi, I'm new to android, but tech aware. Not sure if this is android or Sensation (I'm on XE with thanks to Mike1986).
I use WiFi a lot, but also wander. I tend to forget to turn off the WiFi when I leave work/home/pub - not top of my list!
Whilst I'm wandering I often try to look something up, when WiFi's scanning, and wait for ages.
Shouldn't the 'system' failover to phone data access if WiFi is not connected - or at least ask me for an action?
As I say, I'm new to this - apologies.
Thanks
yes, it should fail over to data if it is not connected to WIFI.
Correct. If you have wifi enabled, leave the area like to work that has no wifi, then yes mobile network takes over.
But I go one above and use Llama location profiles. Where depending where are based on the conditions you set, you can trigger actions using this app. The app is free in the market and is an invaluable tool for me when I am leaving work, heading to the car with my bt and gets connected because I set my condition to look for a bt device if I am no longer connected to my wifi at work.
Gotta love Android
Hmmm. That's not the behaviour I'm seeing. Just thought it was an irritation. Should failover be auto or is there settings (or apps) to control it? I like the concept of profiles ... But you've got to be more organised than I!

It's auto. Like my n1, whenever I am in range of a known wifi connection, the wifi will auto connect if wifi was left on from the prior location or out of range and back again, if that makes sense lol...
So if you go out and are out of wifi range, and you manually turn off wifi, then no wifi won't auto connect of course.
Yes, that all works fine - when I'm wandering in and out of wifi zones. My gripe/question is :
When I am out of wifi range, and wifi is on (scanning), should the phone fall back to the phone data connection? The behaviour I see is that connecting just hangs until I turn wifi off.
Thanks
Is it possible to have a Local WiFi Hotspot? I have a Galaxy S5 with Verizon. Ever since I upgraded I have been struggling on a 6gb data plan. I own an iPad and an Apple TV and wanted to do wireless airplay for presentations. Of course Apple TV requires a WiFi connection to airplay so I was wondering if there was a way to make a local wifi hotspot on a device without using the internet? It would be like having a wireless router that isn't plugged into a modem. I have never seen this brought up before so I figured I might as well see if it is even possible. What do you guys think?Am I crazy for wanting a local hotspot or does this peak anyone interest to explore?

is is possible to have the hotspot running on the phone and data turned off, but i dont know what effect that would have on other transfers through the wifi.
only reason i know this is because i just started using ds battery saver app the other day, and i use the hotspot on my phone a lot. i have it set to turn off mobile data when the phone is off, well this poses a problem as the hotspot is still broadcasting but i have no internet connection. fortunately the developer had already thought of this (for streaming music etc, same issue) and put an adjustable bandwidth sensor on the app, so it wont cut off data when the screen turns off is there is a certain amount of transfer present.
i kinda went a little off your topic, but i thought it relevant to explain how i know it is possible for the nay sayers.

I just tried it out and I can get the hotspot to activate with data on and then go turn data off and it won't automatically turn off my hotspot. I will have to try it with the Apple TV in a few days and see how well it works.
I'm using an app to turn off all internet when screen is off. Works great, but it also makes it impossible to stream radio/podcasts when the screen is off.
Do you know an alternative app that can do this, but add exceptions like:
Podcast Addict is not running --> Disable wifi & 3G.
Podcast Addict is running --> nothing
Maybe there's another solution, maybe it can be achieved by tasker. I just noticed that auto disabling my connections saves soooo much power on my fresh android 4.4 stock install on my Galaxy S4
