Widget to toggle "Use Wireless Networks"?

I would like to be able to quickly toggle whether the phone uses wireless networks for location. It seems to be a battery drainer to have it on all the time but going into settings every time I wanna use something like Foursquare is very annoying. Actually, the same goes for "Background Data" which also drains my phone quickly but I can't find a toggle for. Any suggestgions?

Wigle WiFi displays available networks and even incorporates it on a map to view the AP (I think that what the map is for)

Turning off background data??

Turning off background data? Is it good to keep off for battery? I know if its off I can't use market until I turn it back on, but will every else function? Please give pros and cons thanks.

Background data is needed if you use any widget with updates also. So if you use sayyyy the weather widgets it won't sync, same with email. As far as battery life it will not make too much difference. Most items you use this for are able to be customized to an extended time.
Go in accounts and sync and adjust them. I don't use any facebook twitter or news feeds so I just turn the sync off. It will still update when you open the app.
If you want to save battery life then I suggest turning off Data when you aren't using it. Calls and texts don't use 3/4g so leaving it on only causes the battery to drain because it constantly searches for a signal. Turn data off and hook up to wifi whenever available you'll notice a HUGE difference.

Thanks man, so if I'm home on wifi with data off will I still get calls and text or no? Cause I use my phone for business and can't miss calls.
Sent from my PC36100 using XDA Premium App

Mobile data has nothing to do with calls or text. It is strictly for internet, market, widgets ect... Today or tonight before bed. Disable data, wifi and gps and leave it unplugged. You'll be amazed at the 5-7% difference. Unless of course you have a wake issue lol.
When I worked at my last job I had no real time to sit on my phone so I walked around with data and gps off unless I needed them and no matter what Rom I flashed I got great battery life.
Edit:
If you get emails for work though remember they won't go through. Neither will MMS.

[Q] Market and GPS questions...

I picked a Verizon GNex at BB yesterday and have a couple questions...
First, I don't see where to turn GPS ON/OFF -- there has to be a way to turn it off and on -- right?
Second, after installing the apps I had with my Evo I attempted to purchase another app but the "Accept & Buy" button to complete the purchase would not work. I tried this with two different apps. Is Verizon trying to prevent use of the Google Market so they can have you go through there app market?
Thanks,
Brian

I saw that but it's not like any of those option clearly the GPS on/off. The three options:
Googles location service (lets apps use location data from wifi sources etc)
GPS satellites (lets apps pinpoint your location)
Location & Google search (lets Google use your location to improve search results)
OK, of the three the second one seems closest to what I'm looking for but there's nothing here that clearly says it turns the GPS on/off.
Brian

It does turn it off

Actually no! As I said, it's the most likely option but no where does it say that the GPS radio is turned off it just says that is "lets apps pin point your location". Everyone wants to know where you are at all times so they make it more difficult for you to turn off location finding tools because they want you to leave it on.
So, Google may allow you to disable GPS access for third party apps but still permit them (Google) to know exactly where you are because that information is money. If disabling this option stopped third party apps from accessing the GPS but still left the GPS on so Google could keep tracking you the wording of the option gives them the legal latitude to do just that.
So, in addition to wanting to save battery life it's nice to also limit the amount of tracking Google, and pretty much everyone else, does to you.
My Evo 4G had a widget that controlled: 4G (WiMax), BlueTooth, GPS and Wifi -- I would like that on my Nexus.
Brian

It's pretty obvious to me that that option actually does turn off the GPS antenna. It I don't think that there's any device in the world with a GPS antenna that cannot be turned off, unless it's part of the core functionality (e.g. with GPS receivers).

Put the power control widget on one of your homescreens - the middle one is GPS and you can quickly toggle it.

All the toggle in that widget does is turn "option 2" on and off. There is no 4G LTE toggle either. Also, no Verizon isn't blocking the market to force you to use theirs. They don't even have a separate app market.

Yep, after toggling I checked back and option 2 was turned off. It was the most likely option but I wish the wording was more explicit...
I also found that the market problem was somehow related to the fact that I'd added a second gmail account. I had to select the second account and enter my CC info there and after that the market worked just fine.

[Guide] battery fix

Well I was having horrible battery problems and came across a how to on the web and thought I would share this. Hopefully it hasn't been shared already and I apologize if it has. Its a way to wipe battery stats. MAKE SURE YOUR BATTERY IS AT 100% BEFORE DOING THIS
1. Boot into cwm recovery
2. Scroll to advanced
3. Scroll to clear battery stats
4. Reboot phone
5. wait for your battery to fully die before charging it again
And there you go its a pretty simple fix and is good if you have flashed a lot of roms. The guide said not to do it very often tho so I would be cautious but I did it once and now I am getting almost a day and a half with moderate use out of my stock battery! I have seen a lot of complaints about battery life.
Hope this helps let me know your results as I am new here

Wiping battery stats doesn't do anything beneficial - http://www.androidcentral.com/wiping-battery-stats-doesnt-improve-battery-life-says-google-engineer

After doing some research I did see that on androidcentral but can't wiping the stats when your on a new rom improve how your phone reports the battery stats as well?

If on a new ROM, you probably wiped /data, meaning... no more battery stats.

While I'm not sure if wiping the battery stats works or not, I just posted the following in the thread of the ROM I'm currently using since battery life is a big topic there. This is a guide that I came up with after a couple of weeks of analysis and tweaks:
I'm getting at least 48 hours on my battery now, no lie. I've made it a mission over the past couple of weeks to track down all my wakelocks and get rid of all the unnecessary processes that cause those wakelocks.
After 2+ weeks of analysis using a combo of betterbattery stats, badass battery monitor, and the stock battery info, here's a list of what I've done along with running TDJ's Evo3v7 Rom.
DISCLAIMER: These are my findings for my phone and my setup in my location and my typical usage which have worked for me:
-Make sure screen brightness is set to 'Automatic'
-Use Wifi as much as possible Vs data.
-From what I've read Facebook uses a ton of battery (wakelocks) when syncing in the background. I may be the only person on earth that doesn't have a fb account so I don't have to worry about it on my phone, but just keep that in mind.
-Under Accounts and Sync try to funnel as many accounts as you can THROUGH gmail. In your Gmail account sync only what you need when you need it. Do you really need the browser, contacts, web albums, etc synced. Can you live with manually syncing calendar once a day? Keep it to a minimum.
-Disable everything under Settings > Sound > System (the 4 items at the bottom of that list, keytones, touchsounds, screen lock sound, vibrate on screen tap)
-Make sure if you have a weather app that refreshes automatically to only have it refresh to what you need. Some of these refresh every 15min. Really? Just have it refresh manually or on unlock. I've found that to be fine.
-Make sure you're signed out of Latitude after you use it - if you use it. You can't freeze, uninstall etc, without freezing/uninstaling Maps, so make sure you are not signed into Latitude (or any other location service based apps).
-Location, location, location... Under Settings > Location Services uncheck all 3 options... may need a reboot to 'stick' after unchecking (these are sometimes checked by default when first booting up your device from flashing a ROM or you check them not knowing what all they do (I know I did at first). They are helpful when restoring but are a pain on the battery in daily use. This choice is yours as there are other recovery/restore methods but I've found that I don't need these checked at all. (Sometimes even going to Google.com enables the location service and it gets stuck in perpetual wake state, I've found).
-If you don't use Google Talk, simply remove it. Although I've found that 'GTALK_...' still has wake states even with it removed (phone still communicates with Google servers even when the app is removed), it's not near as much as it used to be.
-Freeze the Maps app - if it's feasible. Maps is one app that runs 100% of the time. Take a look in your 'running apps' and see for yourself. I rarely use my maps so I froze it. Since then, location services processes have dropped dramatically as have my wakelocks associated with location. This alone has helped out my battery tons. If I need to use maps, I simply unfreeze it.
-Finally, download and flash this by eugene373: http://forum.xda-developers.com/show...30&postcount=1 This has saved me more battery than most of the things listed above combined.

Hmm your link to Eugene's thread didn't work. But thanks for the info. And I guess that does make sense that wiping data would also wipe battery stats. That's why I'm a little confused about half the people say it works and the other half say it does so I figured I'd try it out

While I agree that turning off services or freezing them does help battery life, it kind of ruins the whole smart phone experience. The reason I have a smart phone is for up to date info at a quick glance. I am sure the info you provided will help some though. Thanks for posting.

Battery drain by maps

Hi guys, I have this problem since last night. Maps are running in background and there is nothing I can do about it, restarted the phone, pulled the battery for couple of minutes, cleared maps cache and data,force stopped and nothing. Never had problem like this before with any of my phones. The phone is 8 days old and everytging is stock. Thanks

Check if you have your location history enabled on your Google account. I do now, and it causes maps to request a location rather often. The battery life on this phone is good enough for me to leave it on though, I find it useful every now and then

This is not True. I went from losing 8% overnight to 2% just by ticking off the 3 GPS settings under location. Now when my screen is off, I rarely lose a %

Glad it's working for you! Yeah this whole time I never knew how much GPS use was actually draining the battery. I actually read an article online yesterday that talks about how GPS uses a crap load of battery. As of this morning, I only lost 1% overnight. I have 3 emails syncing, wifi on, rest of the syncs all on, google now off. No power saving apps installed. I know i'm saying this in all battery related thread but i'm super excited just like you and want to share the knowledge to all our Note 2 buddies ^_^

Battery drain <- Maps Always On <- Now <- 4.1.2
I noticed Maps was grabbing about 30% of my battery drain so I set out to figure out the problem. Conclusions are:
- 4.1.2 seems to have changed how location is used. I had Google Now on 4.1 and never had this heavy a battery drain.
- Maps was constantly running with TWO services
- Maps did not have to be open or visible, and reboot had both come back even after stopping services
- Disabling "Google Apps Location Access" solved the drain but this made it basically impossible to use Google Maps, because
- Maps would not use GPS without "Google Apps Location Access" turned on
I considered uninstalling Google Maps but realized that:
> All my favourite locations are on Google Maps
> Other mapping software also seemed to want all sorts of invasive rights, which I was not going to grant
So I:
* enabled GPS
* disabled Google Apps Location Access
* uninstalled Google Search (aka Now) using a 3rd party tool (rooted)
* looked for a new search software (let's face it this isn't really necessary is it?)
* found and installed Yahoo Search which I must say seems faster, more interesting and does not require unwanted access to my private data
Battery drain is back to normal, I have ful search and maps and GPS use.

Let's face it. Google is king of search. And that has spread to other Google uses, maps being a major player. I think Google needs to solve this by fine tuning how and when maps and/or GPS is used. Another big thing is Google needs to fine tune how our phones retrieve data in general. Apple has and is still working on it. Intel is fine tuning it majorly and you can see some of the results on anandtech where x86 and ARM SOC's are compared on windows RT. Randomly retrieving data for all data and apps is a nightmare. It would be nice if we could fine tune our syncs and data retrieval in set intervals or let the OS have a smart system where if x app needs this and it see 3 or 4 or whatever x apps need to retrieve data in the next 20 mins it will retrieve all in one fell swoop causing less wake locks and more idle/sleep time.

I had a similar battery drain problem... ~8% per hour when screen was OFF! Finally solved it by turning off Google Now AND the Location Service it used. I guess the problem is due to location history collection performed for Google Now.

Guys first thing first about battery draining is your mobile network not configure properly.. if its configure the network will not awaken your phone it just need a second to runing in background.. just realize it after I install configuration message from provider.. I drain 1% all over night.. and get 2day standby battery with medium usage.. 10 hours screen.. and leaving the phone with charging all night is weaken your battery.. first time I forget to unplug and everything change.. battery drain 5% after sleep 6hours..and only last for 1 day with medium usage.. 6hours on screen now I dont know how to make it back like it was.. using note for 3weeks anyone knows how to increase batt life without changing rom or kernel ?? Im still runing stock 4.1.1
