Wifi and 3g icons at the same time?

I noticed that my captivate will often show both the wifi icon and 3g icon in my screen at the same time. I am using wifi to post this but 3g still shows up. This never happened in my nexus one or milestone. This also happens on multiple wifi networks for me. Any ideas?

Mine is just showing wifi and the signal bars

Some apps use your 3G connection to get a rough fix on your location (Beautiful widgets "Beautiful home" or weather bug) there's a lot more. You can usually turn that off and just put in your zipcode. I could be wrong, just a shot in the dark.

I get this too

This doesn't seem right to me. I don't get why it would have both, there is no reason for it. If I reboot my phone, it will just show one or the other but over time it creeps back to showing both. I think its a software problem.

I am also wondering about the wifi. How do you know it's using wifi instead of 3g? Does it automatically switch over to wifi whenever it connects to one?

Thats the thing, I have seen it say I am on wifi but it still shows the 3G indicator and will show 3G activity (the activity arrows on the 3G icon light up).

I saw that, but my Nexus and Milestone don't do that so I'm confused by that.

It might be because you have no apps trying to find your location all the time. That's why some people have 3g on sometimes with their wifi on and some don't.

Well I wish I knew what that was then, because I do have Beautiful Widgets but I also have always had geolocation disabled and have my zip code set in it.

My husband's captivate will show both wifi and 3G when he opens google maps and the only way to get ride of the 3G is to restart the phone.

I'm having the same issue and using "my settings" to disable 3G use while using wifi. Being that I'm on the very limited data plan, I'd rather not have 3G being used when it doesn't have to be. So, if there are some programs that are forcing access to 3G when I'm on wireless, I'd like to know if there's an app or somesuch that will track which programs are accessing this so I don't have to worry about changing settings all of the time?

Hello everyyone. Ive only been using this phone and android since yesterday afternoon. I played with the phone very extensively yesterday and never saw the 3g while i was on wifi and then last night i applied the gps "fix" do you think that could of caused it to show. did all who is having this problem apply the gps fix ?

I believe using a push syncing service like exchange will cause this. on my windows mobile phones exchange wouldn't work over wifi.

Hmm is the default mail app an exchange like server ? So I should pull my info from that one and soley use the gmail app?

My problem showed up after this as well, but I can't imagine that would be the cause of it...

I'm seeing both Wifi and 3G on as well. Oddly enough, only Wifi seems to be on after it sits for a night (both charging and just unplugged). As soon as I disabled Wifi, 3G came back on, but after reenabling Wifi, the 3G stayed on.
As far as I can tell with 3G Watchdog, it's not using 3G when they're both on, but I'm worried that battery life is impacted by having them both on. I'm assuming this isn't normal behavior then.
FYI, I also applied the GPS fix, but I think I was seeing them both on even before I did that.

I get this as well, even when not using maps. I noticed it before I did the gps fix.
I do use gmail app which uses push, but still WIFI should always take over once connected. I noticed though that on the 3G icon the upload/download arrows are grey, not white or red (the transmit/receive colors).
I was concerned at first but I installed the AT&T app and I don't have a lot of data usage. I think its a bug.

I had both icons as well for a couple of days while in a wifi area. Messed with the gps settings again today and I'm back to wifi only icon. Didn't even reboot.

Note drains faster on wifi when not roaming

Hi, when I'm abroad using wifi (so no cellular data), my battery lasts longer compared to being at home, also on Wifi. how can this be possible? shouldnt cellular data be deactivated as soon as i activate wifi?
thanks in advance
Sent from my GT-N7000 using xda premium

Depends on what Wi-Fi network you're connecting to. In theory - 5Ghz network takes more battery than 2.4Ghz or a/b/g network. Also, signal strength also plays it's role - constant low signal forces the antenna to work harder - and at home you always get good signal.
Who knows, maybe that's the reason.

Maybe when you are home the data connection stays in the background waiting for you to drop off wifi network and therefore eats up the battery
but when you are on roaming the data connection is turned off completely to save on data bill
this is just an assumption...
what I usually do is when am at home or work, I turn off data and turn on wifi manually instead of letting the phone choose for me. I've found that this helps in conserving battery

No, thats not how it works.. Your cellular data connection is active, just unused.

I do this too, in fact I use Llama to do it for me. It saves a lot of battery.

Thanks, that's what I thought. But why can't android simply deactivate data when connected. I don't get why there is no such option.

[Q] Slow to latch to wifi? Connect to 3g briefly before wifi.

I have a pretty stock HTC One, and I'm on a particularly sub par data plan, where each 'data session' is rounded up.
I have wifi both at home and at work, good wifi signal and am v close to router etc. I find that if I put the phone into standby and then use it again 5-10 minutes later, it is still connected to wifi, all good. If I leave it for 20-30 minutes, when I wake it, it latches onto the 3g network for a few seconds and then realises there is wifi and connects to that.
I have things like Google+, FB messenger and push mail which I presumed required a constant connection.
Any thoughts on why the wifi appears to be being turned off as it entertains deep sleep?
I can just switch data off when at home or work but I don't want to have to rely on that sort of thing, and the apps that do that for you based on GPS etc aren't that appealing either.

Look in adavanced settings under wifi. Should be able to set it to keep wifi on during sleep

Thanks for the reply. Yup I have that set to always. Seems to happen both on my home and work wifi, despite great signal strength. Sometimes it seems it does happen even if the phone is unused for 5-10 minutes.
I assume this is actually pretty common and most if not all phones do this, you probably wouldn't notice unless you were tracking each connected data session.
I was thinking the phone must do something like, wake, spend x time looking for wifi while simultaneously connecting to 3g, then when wifi is found it is connected to and the 3g connection is dropped. I guess I'd be looking to delay/postpone that connecting to the 3g network for 5 seconds or so to give the wifi time to establish.
Probably nothing I can do really.

I haven't noticed any problem staying connecetd to wifi while sleeping and Ive looked at the notification bar many time before ever unlocking the phone, just to make sure wifi stayed connected as its suppose to and it does. Only see 3g when Ive set it keep wifi on during sleep to only when plugged in and I dont have it plugged in. I also have best wifi performance checked. Dont think that makes much difference though. Im also stock at the moment

Better Battery life on LTE/HSPA+ than WiFi

Hey all,
Does anyone else notice that they get better battery life while on LTE/HSPA rather than on WiFi? I decided to leave my WiFi off yesterday to see how well the phone does while using the GSM radios. To my surprise, the GSM radios were more efficient. I also noticed that on the stock battery app there were way fewer instances of the phone being "awake". With 11hrs off the charger,1.5 hour of SOT, 45 minutes of music I had 73% battery left. To me this is solid battery life. With the same exact routine and WiFi on I have about 65% battery left. Not a huge difference but enough to where I don't feel the need to juice up during the day if I am going out at night. I'm doing the same thing today to see if it is an anomaly but so far it looks like it is the same as yesterday. Anyone else seeing this?
Variables:
Stock, unlocked, not rooted.
brightness set to 1/3
T-Mobile $30 plan.
This is in NYC which has great T-Mobile service, that being said the bars in the battery life menu are "yellow" indicating the signal is "ok"....mostly because the testing was done indoors.
Google Now enabled.
GPS set to battery savings
Scanning always available (in wifi settings) turned off.

I agree. I just turn off wifi, use LTE only.
But I have to turn on wifi when I download something or update, I have limited data plan :crying:
If I have unlimited data plan, I will completely turn off wifi

Same here today. All day with data (tmobile) and had wifi off. Was getting better SOT on data vs wifi.

Is there a way to enable/disable WIFI automatically based on location? through an app or native os function?

This probably had something to do with the n5 having only one main antennae for cellular connections. The phone isn't connected to LTE and gsm at the same time, just LTE and switches back to gsm when a call comes in. Therefore when only connected to a cellular network only one radio is on. In contrast with Wi-Fi on that is another radio consuming power. Someone correct me if this is incorrect.

I've noticed this recently but my situation is because when I was on wireless I was getting a lot of wlan_Rx_wake wakelocks. I obviously wasn't getting it when on LTE alone. I've managed find the issue on my network at home . now I have to figure out what the issue is on my hotspot. My phone has been sleeping like a bear in the winter now. I imagine a lot of people are probably getting a lot of these wakelocks. I wonder what makes this phone susceptible to it and not the other nexus devices.

10 bucks is ridiculous. I found Llama that does practically the same thing (if not identical). I've set it up to disable WIFI as soon as i leave "home" and enable it when i get to "work", as well as set up other actions (quite mode after midnight etc) within the profile.
and its free

If you're comparing lama to tasker specifically, llama does about 10% (being generous) of what tasker does. Although there's a lot of learning to be done.
I'd pay 100 Bucks for tasker

Well the nexus5 utilises envelope tracking when ring on LTE. Maybe it's doing its job... http://androidcommunity.com/nexus-5-getting-battery-boost-from-qualcomms-envelope-tracking-20131101/

An interesting question in this forum post but does this not really depend on the strength of the wifi/LTE signal? For me on wi-fi at home I can easily get 6 hours+ SOT. On a normal day with a mix of LTE & Wi-Fi I generally after between 4 and 5 hours SOT. My wi-fi signal at work is stronger than the LTE signal so I generally use the strength of the signal as a rule of thumb as to which will provide better batter rather than just the signal itself.

Hi, I just made this app:
https://play.google.com/store/apps/details?id=com.sdev.autofi&hl=en
Basically uses GSM/CDMA and GPS Locations to automatically turn on/off your Wi-Fi. The app is for free.
Note, this is my first app, so if app crashes please submit the report so that I can fix it.

Leaving my phone over night with no wakes showing it will lose 3x as much battery idling with the screen off then on WiFi.
This was using "turn WiFi off during sleep" option to test if I could further minimize over night battery loss. I lose about 3% over 8 hours of idle, but on my data connection it lost 9%.
When the WiFi turns off the Data connection turns on, and vice versa. So only one is only ever being used at one time.

Data and Wifi completely drop, have to do airplane mode to turn it back on

I don't know why, but this is a consistent problem and it's getting annoying. I will only have bars, but no wifi or internet connection. This just randomly happens and I don't know what triggers it.
I have to turn airplane mode on and off to fix the problem. Is there something that is causing this?

I have had the same thing happen,but only once or twice,I chalked it up to my home WiFi threw Comcast ,I've been having major problems with my Comcast modem dropping WiFi or to slow of a connection,think I have to replace the modem just been to lazy,but I have the smart network switch on in my phones wifi settings so I thought maybe from the signals switching so much it froze or something,but yea it did same thing I had no lte or 4G next to my carrier signal,the wifi was not allowing me to turn it on,or scan for networks,wasn't even showing any so I did the same thing hit the airplane toggle and it came back.

Sorry i have no others solution for it.

I just posted a thread about the EXACT SAME issue. It only seems to happen overnight, but when I wake up in the morning my wifi has been turned off and my 4G LTE isn't working. When I try and toggle wifi back on it gets stuck and never reconnects/turns on. My solution has been to restart the phone.
I'm thinking since this seems like a rare problem, that this is a device-specific issue. I'm going to try and exchange mine this weekend due to this problem and hopefully get a properly functioning GS5 instead.

Have the same issue (made a post about it already in this forum). Usually happens when there is a large fluctuation in signal. Grocery store where I get no service results in no service when I leave the store as well. Have to cycle airplane mode like you described.
WiFi hasn't done it yet.
Another forum member suggested it may happen if using an older style SIM, which I am (from my S3). I haven't been up to change it yet. What SIM are you guys using?
http://forum.xda-developers.com/showthread.php?t=2744472

I typically have this happen when I'm at home at night, while my phone is plugged in and on wifi. Just disconnects at some point overnight.
I'm using a brand new SIM provided by AT&T when I upgraded in store.
Very strange issue and is random. For instance, it didn't happen overnight last night.

My S5 just started dropping data randomly and causing my battery to drain with almost no usage... I tested using Skype in a good 4G LTE area and will start out with 4 bars and the 4G LTE icon but as soon as I try to initialize a test video call over Skype the signal immediately drops to either no bars at 4G or it will go straight to E!? I haven't had this issue in a long time and it just suddenly started. At first I figured maybe they lost a tower but now this is going on almost a full week. I've got unlimited Data so I know that's not the issue, it has a brand new SIM... I'm going to AT&T and see if they have an answer or if they'll swap it out. Annoying!
Also annoying that sending a simple text will fail... ugh no root and now no data! :what::banghead:

I've had this happen several times, but only at my work. Reception is poor at my office, and the company WiFi requires browser-based login each hour, which I switch to many times a day.
The phone basically stops using all radios EXCEPT bluetooth, showing a circle with a line through it. I've been rebooting the phone to restore connectivity, but will try toggling airplane mode next time. I haven't noted any strange battery drain.
I haven't seen this issue when wifi is disabled.
I didn't notice it locked up a few days ago and drove home where cell reception is very good. The phone didn't recover until I rebooted it.
I have a brand new SIM from ATT and use a Gear 2 (which is greatness, btw)
I've done the following:
1. disabled the damn ATT hotspot app
2. Disabled/enabled the Wifi connection check setting
3. Did a full factory reset
This is getting close to a deal breaker for me.

As an update...
I have this issue basically every work day with the aforementioned environmental variables
Today, I:
Disabled Bluetooth (left the gear at home)
Disabled wireless
Switched radio to 'LTE/GSM/CDMA Auto' with instructions in this thread
The radios haven't locked up and reception is much better.
I'll try leaving WiFi/BT on and use my Gear again next week.

For anyone who is still interested, changing the modem setting seems to have resolved the problem for me. It also improved connectivity in weak areas a good deal.
Unfortunately you must enter the key sequence to toggle the radio each time the phone is restarted.
