Does using wifi drain the battery? Is it better than using the actual 3G or 4G?
Sent from my HTC Vision using XDA App
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.
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##

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.

Are you at least rooted? All my settings took effect instantly without rebooting. I maxed out the dB and idle time.
Shortly after I got my VZW Galaxy Nexus, I opened up the data usage monitor to change some settings. It went a little crazy, then it force closed. Now every time I try to pull up the Data Usage screen, the "Settings" app just freezes, then eventually force closes. I can get Data Usage to open, but I have to put the phone in Airplane Mode first. Once I turn Mobile Data back on, it freezes again.
Anyone else experiencing this? Any suggestions for a fix? I suppose this isn't crucial for me, but it would be nice to have it working
I have exactly the same issue. It was present with the stock Android 4.0.2 (ICL53F) and with the Revolution HD 2.1.5 after rooting.
However I figured a way to start the data usage normally (without going to Airplane mode). You have to go to Settings > More... > Mobile networks > Check off the Data enabled box
Then go back and check your traffic by clicking on Data usage
This is the only workaround I found so far, except for the Airplane mode (which is more time consuming, having in mind that you have to enter your pin afterwards and look for network).
I believe that this is an ICS bug and it should be fixed. The data usage cannot be opened while you are using your data connection, that is bs. Instead of force closing I sent few reports to Google via the phone, but i don't think they will be acknowledged when coming from a rooted phone with a custom image.
Mine works normal and I'm on stock 4.0.2.
Do you have Mobile data on?
CDMA or GSM

I figured another workround. Set a data warning and it will no longer FC. At least that worked for me. I set it at 1.6 GB. Although I have unlimited data plan I have never reached more than 1 GB of traffic anyway.

HUGE BUMP.
But is the only place I've ever seen this issue discussed.
What happens if you just can't access this screen?
Not even with Airplane mode...
I don't know what to do... and I'm on Kitkat now. Still same problem.
Anyone else experiencing this? I've had this going on for about 5 days now and for the life of me couldn't figure it out. I notice that whether it's my 3G or my WiFi connection, my phone was continuously streaming data. If I'm at work where I don't have WiFi activated, my 3G is on non-stop streaming, making matters worse, sucking the life out of my battery. Of course my phone was running warm. Imagine that!
I know there's got to be something running in the background and I think I nailed it down to Google's email app. There wasn't any huge file to upload/download which I think could have caused this to happen.
Luckily I may have found a remedy. Microsoft has finally gotten around to updating their Hotmail software for ICS. It's been over 30 mins since the Hotmail app install and the data transfer thingy doesn't seem to be so intense now. In fact it's down to nil.
Strange.
Hotmail.. ಠ_ಠ
yea, i dont think its hotmail.
go to data usage...thast why its there..you can see which app is taking the most data...you can also stop the background data for that app
Every since Verizon pushed the Lollipop update to my N4, my "Mobile Data" turns back on all by itself after it has been disabled. It even turns back on when I am connected to wifi.
Has anyone else experienced this and if so can you please explain how I may fix this.
Thanks in advance.
Not exactly that but I have noticed that now I'm always on 3g when I'm usually on 4G all day long same area this is crazy
Mine is also randomly turning on Mobile Data too after the Lollipop update. I have a small data allotment with VZW, this could send me into overages.
I seen on one thread, searching through your downloaded apps to find out which ones have "change network connectivity" in the permissions. I happen to have 6 of them. Some you can disable, but it removes the updates, other you cant disable without removing it.
Another recommendation was hitting settings from the pull down menu, wifi, advanced, then uncheck the "smart network switch". Mine wasn't checked to begin with, so I'm out of ideas til I start removing apps one by one...
The data has been turning on by itself during sleep time on my Note 4. It caused the phone to use 500mb of data in one nite. My data is always off, wifi is only on when using the phone otherwise it's off too. I called Verizon and they have no clue. This is my 2nd new Note 4 for myself & my wife, nothing but problems. Think we are going to switch to anything other than a Samsung phone.
Well, I've systematically removed all 6 apps one at a time. The Youtube and Facebook apps, I was only able to disable them instead of removing them completely. In the end, the phone still turns on Mobile Data by itself. This must be something internal with Lollipop. I have a small data allowance and I'm afraid its going to go over simply because it wont stay OFF even with WiFi available!!
I would call customer service and have them ship you out a replacement. This is our 3rd phone and hopefully it will work as it should. Good luck
Outcast,
I've had my Note4 since it was released in November. It didn't have this problem with 4.4 Kitkat. It's something new with Lollipop and I doubt a new phone would solve this problem, could be wrong.
How involved is it to go back to Kitkat?
I'm not chancing voiding my warranty. They replaced my phones by them and not by request. Our phones get hot and get a warning then shuts down, apps close constantly and the phones consistently reboot on their own. Then the data turning on by itself. The other problems I don't think are software based but hardware failures. The data can very well be software related.

I have the same problem and i used up so much of my data when i am at home where the wifi connects automatically on everything else. On kit kat this never happened and i am attempting a downgrade so you might want to try that.
I was having the same problem with mine. I also live on the edge of 4g area, so it was constantly swapping between 3g and 4g. In addition to using some data it was killing my battery swapping between 3g and 4g. Using almost 10% per hour when not being used. I disabled most of the verizon stuff, support and protection, Verizon navigator, caller name id, message+, and verizon location. I turned off facebook location reporting in the app settings, and disabled google location. I did all these a couple at a time and would reboot to see if it fixed the problem and after all those were done i rebooted and wiped the cache and the prblem was gone. I turned google location back on so far and its still working the way it is supposed to. It shows a greyed out 3g symbol and my battery life is much better. My phone sat off the charger all night and only dropped 4% and in 5 hours of moderate use its down to 77% left. Wish i knew exactly which app was causing the problem to help you out better but hopefully you can try those apps and settings and get the same results.
Well it worked for about 3 days, but this morning data and wifi were both running again.
Data usage Samsung Galaxy Note 4
Been having the same problem even when I disconnect data ten or fifteen minutes later data is back on. And I've noticed even if I am connected to Wi-Fi data trumps it and I end up using a ton of DATA when I've been connected to Wi-Fi all day, getting seriously upset cause I never used this much data before.
I have same problem with my Note3 running Lollipop. Have tried every suggestion I can find to turn off data, but it is still runs, unless I am on wifi. Data is set to off, 4g symbol in notification bar is greyed out, but data is still on. I have found forums all over the Web with other people with this problem, but no solution yet. My phone is unlocked but not rooted.
