Desire Network Connection

Hi
i would like to know if its possible to turn off the gprs connection and only use it when weather app needs it and then switch it off again
i have seen a few settings but cant understand them properly
one is always on and the other is mobile network(or somthing simular).
i have turned always on to off and left the other on.
also the pre installed weather app doesnt save my setting to update automatically, is this a bug, manual update doesnt work at all unless using wifi.
thanks

anyone messed around with my issue

Temporary fix. I don't even have my Desire yet but I've seen on pretty much all Android phones a widget which will let you turn on and off each of the radio's (WiFi, Bluetooth, GPS... etc.) by hitting the corresponding button, much faster than going into settings and turning them all off manually...

Does wifi kill battery faster?

Does using wifi drain the battery? Is it better than using the actual 3G or 4G?

I'm sure someone has a way more technical answer but I would think not. I have no issues with drainage on wifi, as on 2g its on the network constantly and not continually searching for towers.

If you are connected to a wifi network, it saved much more battery than using 3 or 4g. However, if you leave wifi on but don't connect to a network, it will drain battery

ok cool thanks alot man. Idk when I'm home I just like using wifi better, correct me if I'm wrong but it seems faster. Thanks again

Turning on anything more than necessary will kill your battery faster. Not always by a lot but everything does and wifi wouldn't always be faster because it depends on the wifi's local area connection. Best way to save battery is to go in settings/applications/manage applications the force close anything you don't need running. Make sure you know what it is you're closing or you could run into some problems. If you end up killing a system app and it won't reopen itself, its nothing a reboot won't fix.

DO NOT DO THIS.
Android has its own automatic task management system, and its best if you just let it do what it does best: manage on its own.

Well gee I do it all the time and it works fine. If it wasn't intended to be used I don't think it would come without root permissions and anyone who isn't an idiot will realize that force closing android system will cause problems. But if you wanna suggest a task manager that doesn't actually kill apps and adds some bloat ware, be my guest.

He's not going to recommend another task manager/killer, because Android already does it by itself. Plus, killing a task that is not finished just causes it to respawn. Task killers are unnecessary, and may actually hurt performance and battery life.

I agree that it's best to let Android clean it's own house normally, however I'm getting a little bit jarred off with certain apps starting themselves up at boot-time.
Paypal app for some reason has installed a service on my phone, despite the fact I've never even logged into it and I can't see why it would need a service running all the time.
Also since the latest Google Maps upgrade there seems to be something under my running tasks called Rate Places. I've not used the check-in service on GMaps at all, nor will I ever.
As well as this, since I've been running a modded CM ROM (SparksMod Extra Hot Sauce) then I constantly have Wi-Fi Calling running - again this is useless to me cos I'm not on TMob US.
Any suggestions for a decent app which can stop all these things running before they ever start, and keep them stopped?

Try "Autorun Manager"
I use it, but SOME apps will auto-restart. I think you need the Pay version of Autorun Manager to prevent those from re-launching.
I use the free version, and it gets rid of some of the problem.

WiFi is definitely causing massive battery drain on my G2 with CM6.1.1. I leave it on at night, and if I have 50% when I go to sleep, I'm down to 3% in the morning. Without doing anything.
I'm not quite sure why this is happening, but it is, and it sucks. I can't go back on 3G/4G right now because I'm at just about 4.8GB, and I don't want to go over my 5GB soft cap.
I wish I knew why WiFi was causing such battery drain...

Do you have anything updating automatically (Email, facebook, etc)? That would be my best guess. I leave wifi on when I'm at home and it isn't that bad at all. Also, I'm sure theres an app out there to let you see what is using the wifi for updates and such. I just don't know of one off the top of my head. I have an app like that for 3G data but it doesn't do wifi.

I just went through every one of my apps to make sure that nothing is set to sync, except Google Voice and Email. My battery is at 50% right now, so we'll see what it's at tomorrow morning.
As you can see from the screenshot, WiFi is using quite a bit of battery. I'm not sure why, but hopefully soon (after some testing) I'll have my answer.

Yup, 2 nights in a row, my battery has gone from 40% to dead, simply from sitting on my night stand. I wonder if this is why T-Mobile discontinued the G2... because they knew it would have battery issues, and they didn't want to deal with serving warranties? Hmmm...

Its a bit of a leap of logic to link your personal battery issue with T-Mob discontinuing the phone. T-Mob has a good number of Android phones coming out in the near future, with T-Mob really ramping up their support of Android devices. So its been very reasonably speculated that they are discontinuing the G2 in order to make room in their lineup (and stockrooms, etc.) for the new phones.
I get a full day of moderate usage on my Vision, and can get close to 2 days with low usage. That's very typical for a modern smartphone. I usually get in the range of 2-3% battery drain per hour when the phone is idle. And that's with WiFi always on (even when not connected to a WiFi network) and auto sync of Gmail and HTC stock and weather apps. You haven't mentioned how long "overnight" is exactly, but I'll assume 8 hours or so. So your phone draining from 40% to dead overnight seems unusual. WiFi typically uses less battery then the cell data network, when WiFi is available. I suspect there is something else going on, besides just being on WiFi. If the cell reception is dodgey in your area (or fringe 3G reception), this might run the battery down (even if you are on WiFi) as the phone is constantly searching for signal. Or your radio may be mismatched to your custom ROM. Or you may just have a bad battery. Also, was the battery drain any different when you were on the stock or other custom ROMs? I personally haven't witnessed the battery drain to be significantly different across the ROMs I've tried. But that seems to vary, as there often seem to be people complaining about this or that ROM causing more battery drain.

The reason I thought it might be a hardware defect issue is that my wife and I got G2's at the same time. I rooted mine and have been running CM6.1.1 for a few months now, and my wife has kept hers stock. However, the battery issue hit both our phones at almost the exact same time.
It sounds ridiculous, but conspiracy theories are fun to play with. The fact that I've been rooted so long, and it JUST happened weirds me out. Add my wife's phone to the equation, and it's even weirder. I kept my phone on WiFi and 2G networks only last night (yeah, about 8 hours), and the exact same thing happened.
Maybe I should just get a new battery, I don't know. But I do religiously delete apps I don't use and make sure the ones I do use are syncing as minimally as possible.

How do you prevent 4g signal from zZZ-ing?

It's becoming rather annoying that the 4G signal constantly goes to sleep once the screen is off. I was on my friend's Galaxy S 4g on T-mobile and his managed to stay on constantly (it's actually the default connection and you won't even see that 3G connects). Once the screen on Epic turns off, the 4g signal goes on sleep, making me lose any type of internet connection...
I've tried this way: http://www.groovypost.com/howto/mobile/prevent-phone-4g-wireless-connection-sleeping/ but has proven to do nothing to help with the situation. Anyone know how to prevent it from sleeping??

Unless you're tethering why wouldn't you want it to sleep?

T-mobile's 4g is 3g turned up to the max. Sprints 4g acts like wifi.

Mainly because i want to be loading my webpages at 4g all the time, turning it on and off is just annoying and slow, since battery isn't an issue for me I want to take advantage of the speed game

Uh, 4G icon's Zzzz means that it's idle. Just like when the 3G icon says D instead of showing arrows.

You aren't losing a connection. It just means you don't have any data activity. Same goes for 3G. If it *isn't* displaying the idle icon, you're transferring data. If it is, then data has been idle for a few seconds, and the radio goes to low power to avoid burning through your battery. It's not sleeping though. Also, you're probably relying too much on the icon - it's slow to refresh, and often doesn't correlate to an immediate data connection. So, just leave it be. Nothing's happening to your data connection, data's going to and from your device as it should be. (Your laptop's WiFi, and also the Epic's, do the exact same thing.)

You are loosing a connection when this happens. I've been looking for a fix for this for a long time. Unfortunately I think that the sprint side is at fault. I use my phone to hook my desktop to the internet and see this going on all the time. Perhaps some kind of app that pings the server every 3 minutes might help.
My work around for this is to set the display to not turn off when connected via usb in development settings.

Perhaps there's an issue with your ROM? I tether *constantly* when I travel, over 4G. When I'm just sitting there doing nothing, it switches to idle. I've *never* lost a transfer, a session of any kind, or anything otherwise, and I generally stay tethered for hours on end. Are you positive?

Sorry but i never lose a 4G connection if i'm transferring data EVEN when the screen is off.
For example, i use Tune In to stream BBC London 94.9 all the time and i turn off the screen, and the stream goes on just fine.

Call sprint and ask them for your MSL number. Its a 6 digit number. Go in your dialer... now
##3282##
Hit view
Wimax
Enter your msl
Long press on idle sleep and change the value. If im not mistaken its the unit in minutes. After your.done reboot because 4g will.become. unresponsice for some odd reason. The highest is 300.
There you go

I think the phone let's certain apps hold a connection open while in standby while others don't. For example pdanet keeps it open but downloading install files for games like dungeon defenders the phone lets the signal sleep. Anywho the above works.

I've done that already- doesn't work.
How do I know there's no connection? It's simple- open up gTalk on 3G (even when it's on D) and have someone IM you, it'll go through (almost instantly). Now repeat with 4G, turn the screen off and wait a few seconds or just know that it's on zZZ. Have someone IM you, it wouldn't go through until you establish an internet connection (hit refresh in your gmail app to revive it or go browse the internet), only then will the IM go through.
So all in all, it proves that there isn't an internet connection when it goes to zZZ

Yea 4g works like wifi hence the sleep. Somethings wrong with your phone or rom I've done the above on.both my epics on multiple roms and its always worked. Also I hope you know its going to shut off regardless. It only stays on it there's an app actually downloading something. I dont know of a way to keep 4g permanently on. This will only prevent the sleep when the screen.is shut off. Without it 4g sleeps no.matter what your doing. Sounds like your just going to have to.deal with it until someone with enough need comes up with something.
Sent from my SPH-D700 using XDA App

well I'm using the sprint stock rom....sigh* this sucks

I can only conclude that leaving the screen on is the only way to keep the 4G connection stable- which sucks a lot since the display sucks up more battery than the 4G radio does!
If anyone comes up with a solution or anything (maybe flashing a different rom would help- if it does, please recommend some) please let me know! Thanks a bundle!

I am having the same problem as in the OP, except on my EF02 deodexed ROM when it comes out of sleep it doesn't re-establish the connection.. Anyone have any suggestions?
[email protected]
Edit: I forgot to mention that I have reflashed through odin, and cwm to no avail. I also have tried EC05, EE02, EF02, and EF10 modems. It seems to be doing it on all of them.

I'm fairly certain it stays connected, it's just not active.
The TuneIn example is great, that's an app I use frequently. I also use Pandora and Slacker and they also continue to transmit data even with the screen turned off. If I get an email I get notified, if I get a facebook message I receive notification, if I receive a video call request it notifies me.
It has been the same for me both on the stock Epic and now on SRF 1.2, there is no reason you should be losing the connection if it is stable prior to the screen shutting off, IMO.
Maybe there is something more going on here. The only times I have ever had problems with my 4G connection is when I had certain apps installed, they tended to disrupt the data. Try uninstalling a few data intensive apps and see what happens.

Thanks for the suggestions. I actually created a new thread because I believe my issue is different than this OP. It's under EF02 4g issues or something. (can't remember right now) But it is specifically when the screen turn off. I just went in and kept the screen on while plugged in and it was fine. For some reason after the screen turns off and I turn it on a minute or so later, than even though 4g shows active it won't transfer data. The only apps I have that might be data intensive is email, or possibly SNS pulling FB data.

I've had issues with this also, as I stream movies off the net on my Galaxy Tab 10.1 while tethered wirelessly to my Epic. Once the screen is off and you leave it be data will go through for about 2-3 minutes then stop until I wake the phone up and turn on the display. It's annoying while watching movies and every 2 minutes it stops because the data connection on the phone stops.

App that alternates WiFi/data automatically?

Hello,I'm looking for an app that:
1.Enables WiFi when there's a network available (based on location or checking periodically every hour for example) and disables data the moment it connects.
2.Enables Data the moment I lose WiFi connection and automatically disables WiFi.
Simple,but I just can't find such an app.Most of the just switch on WiFi using location based rules but also leave Data ON.
Looking to maximize battery life without having to keep switching WiFi/Data ON or OFF myself.

Im pretty sure you can do that with tasker. Its a really cool app, you should try it out. Though it is quite complicated and not for beginners, good luck

OK,thanks.Is there any guide on how to get it to do what I describe in the first post?

[Q] Rom or app to fix either bluetooth handsfree or disable 4g

Hi All,
I love my captivate, but replaced it with a droid 4 so I could switch off 4g and use hands free. The issue I have is, where I live we have poor cell coverage except for 2g. If the phone has even the faintest sniff of 3g or 4g it connects to that. This results in no calls or few calls getting through, hence needing to turn it off. All the roms I have tried don't seem to allow you to select 2g only (my droid does). Also all the roms I have tried prior to august have Bluetooth issues and have no audio on any of my 3 HF kits. If I use the standard at&t rom, they all work, just stuck with 4g.
I have tried the service menu, but that only works sometimes and I find myself missing a few calls and spending half my time messing with that menu. Any apps I tried, only actually link to the phones menu and don't actually do much more than provide a shortcut.
Please help, as I would prefer to use this over my droid, especially as that has the dreaded earpiece issue. AAARRRRRRRGGGGG

Hi
Have you tried sediROM and if so: are your BT devices working with it?
If that is the case and you want to permanently disable 3G and 4G for the device:
Open dialer
Type in: *#*#2263#*#
Tap menu 3 (GSM bands)
Select 1 (All GSM)
Tap the menu button and press "end" if the menu does not close automatically after that.
Hint: never use the "back" key while in service mode!
That way you will effectively disable or enable 3G and 4G. You can revert by choosing automatic instead of menu 3.
As this is something you do not want to do every day I can recommend the app Llama (2 "L"). With this you could switch on/off 3G based on your location (based on the phone cell , gps e.g. or based on whatever you want). You need to specify a rule within Llama where you define a event and an action. The action can then be to use 3G etc or disable it e.g. when you leave home enable it and disable it when come back.
If sediROM works for your BT devices then you should be fine with either the above permanent solution and/or using Llama.
All the best

Thanks for this. I have flashed phone and will try over the weekend. Thanks for the code hint, I never used to press end, which may be half the problem. I have downloaded Llama too. On initial setup it doesn't seem to be switching to 2g. This could possibly be a error on my part and will continue playing. FYI the code is actually *#*#2263#*#*

Thanks yeah I typed the code with my phone so I missed the last asterisk but you figured it out already.
Llama itself will do nothing until you tell it what to do.
So you need to add a rule within Llama first and then you need to add an action like disable 3G,4G.
Check the doc here: http://kebabapps.blogspot.de/p/llama-handling-guide-instructions.html
In my case the service menu method is working fine nevertheless. Llama would be a fallback only or if you want to have some automatism only (well THEN Llama is a great tool btw).
Have fun

FYI
After a week with the captivate, I was reminded just how much of a pain in the butt all this is. I was happy I had BT, however the 4g just won't go away. I think with the pac rom I could at least get that to stay off, but had no BT.
Llama wouldn't stop 4g. I even had it set to ignore the 4g towers it could see, however it seems to have some kind of AI and knows when you have relaxed that you have it sorted, and would then connect to 4g even though it says "ignore". The service menu does the same and even though you go in and check and it says gsm only it will be on 4g and I would have to enable and save it on, then again off.
Also the wireless in this rom seems to take a long time to wake up when you wake phone.
Close but not worth the hassle.

All the 4g issues were with the original ics rom and also with sediROM, however I could connect to bt. most of the jellybean and kitkat roms were good in controlling 4g, but would not connect to my bt headsets.
Good work on the sediROM though
