[Q] Automatically switch data off when on wifi? - Nexus 6 Q&A, Help & Troubleshooting

I'm coming from a Note 2 and I'm somewhat confused as to how this phone handles everything network related. On the note 2 whenever I would connect to wifi, my LTE symbol would disappear and show only a wifi signal, and I THINK the mobile data was switched off until the wifi connection dropped (I'm probably wrong). I also wasn't as concerned about battery drain with that phone since I had a 7600 mAh battery.
On this phone, regardless of if I'm connected to wifi or not, the cell data (empty "bars") logo always shows at the top. Now normally this wouldn't really bother me, except "cellular data" is using nearly 5x the battery that wifi is using. Are phone calls/SMS also tied to the same data stream/radio as the LTE? I'm on wifi for around 80% of the day. I didn't know if disabling cellular data would stop me from getting phone calls/sms. Again, I'm not sure with the note 2 if that was just a touchwiz feature or not, but I was wondering if there was some way to automatically disable LTE radio (if it isn't tied into calls) when I connect to wifi. Cell standby is my number one battery drain after the screen.

Cellular data is off when on WiFi. The only time you'd see it on is when a MMS is coming through.
Cell standby is just your radio connected to the tower.

battery drained

is there any way it can help my tilt from preventing battery drained..it was fulled charged at 11 pm (only instant message was still running but no messages), woke up at 9am and theres only 53% battery left. i barely listening to music but when i do it killed faster.
changing radio can change the rate of battery drain
What type of Messaging were you running? What program? Some keep a continual data connection & if you're in 3G territory that can easily account for that battery drain.
I used to leave HSDPA on and auto check email every 10 mins, my battery only last more than a day even without any phone call in this time. I was then disabled the 3G + HSDPA, just leave the GSM on (changed this in the phone's band), my battery now last about 4 days and still have some power.
Your data connection kills your battery severely, this may be what caused your battery drain 50% over night.
my 3G is always on. I have internet and everything. does 3G interfering my internet connection?
u can get very good battery life when 3G service is deactivated.
also make sure disable wifi, make sure when not in use no application will auto on the wifi...
make sure device lock is set to lock all buttons.

what does HSDPA do? i turned off 3G already. i pay unlimited monthly internet so are those things that i turned off interfering anything from it? i Disable HSDPA already and my internet still connecting. sorry for many questions but im pretty new at this tilt.
Just make sure the icon and or mobile operator name has no 3G indication. Yes u still can get connected via internet, which is through your GPRS, which online activates when as you wish. 3G is passive mode whereas GPRS is dynamic.

Toggle between WiFi and mobile data with tasker

Hello. Does anyone knows how to make a script for tasker which switch mobile data off if WiFi is connected and mobile data back on if there's no WiFi connection? For the last 3 or 4 hours I'm searching for this and can't find nothing.
Also, I want if there's no WiFi network, to switch WiFi off (so mobile data will be turned on).
I managed to do something, but it didn't worked. When I enabled the profiles with WiFi and mobile data both turned on, the mobile data turned off, then WiFi off, then mobile data on and so on, in a loop.
Wouldn't that be redundant? The os already does that.

Thanks for the response. I know that if WiFi is connected, I'm using the internet from it, but mobile data is still active, right? Even if there's no traffic from mobile data, that's still on. Wouldn't that be a source of battery drain?
I set my data to turn off if my phone is connected for 5 minutes to a wifi. Important: set collision handling to 'abort existing task'.
Here you got pictures.
Edit:
if you are further interested in battery savings, you can read my thread "[BATTERY LIFE] How to get up to 7+h of screen-on-time"
This is absolutely redundant and unnecesary, when the phone connects to a wifi, it disables 3g/LTE data connection by itself. When you connect to a wifi you can see how the 3g/H/H+ icon above radio signal dissapears. The radio chip inside this phones can be used in Wifi mode or 3g/4g mode for data connection, but not both at a time. It is technically not possible.

The moment you don't have wifi anylonger, the phone starts a fullburst search for wifi and 3G/4G networks (even if I don't want wifi/data at the moment). and this drains a hell of a lot of battery. then (if you go out e.g.) it finds a 3g/4g-connection which it tries to keep up (drains a lot battery) and in the same time searches for wifi-networks (also drains battery)... very inefficient use of battery
So I deactivate data after 5 mins automatically via tasker and turn it on manually when I need it (could also automate that, but I'm lazy). This way I circumvent all these battery drains
Additionally:
Under normal circumstances I'd also set wifi to "turn off if not connected" (in settings) and "optimize wifi for battery life", but I use a custom stock kernel that has issues with these settings so I need to leave wifi on all day

Umm, ok... But this has nothing to do with what the OP asked, or what I said.
You may try e-robot from play store.
I have a command for that, after wifi disconnects, wait for 30 sec. If still wifi is not connected, automaticcaly disables wifi.
Same as for bluetooth. When i leave my phone in my desk and gone for a while, 60 sec later disable bt.
You can do what ever you want.

2g or wifi

I wonder what is the connection that uses more battery, 2g or wifi.
I only use the internet to update the app lockmix, then the 2g enough for me, but I was wondering which spends more battery if it is 2g or wifi
2G uses very little power in the background, but it's very slow so transferring much data over it will use a lot of power because the radio will need to be on constantly.
WiFi uses a significant amount of power even on standby - that's why WP8 defaults to turning WiFi off when the screen is off - but it's probably worth using when available if your only other option is 2G.
BTW, are you sure you meant 2G? That's archaic; 3G has pretty much entirely replaced it and 4G is become more and more common.
I only use the internet on your phone to update the lockmix application (for screen lock), the 2g is enough. I have to have an active connection, my doubt is on wifi or 2g due to battery consumption. my wifi router this to 2/3 meters away and have speed of 30 mb.
But obviously, battery drain's on 2G network, & no issue about Wi-Fi distances, but it also drain's down when background searching & attempt to connect to the network at multiple times.

Issue with WiFi calling?

On my notifications, it says that WiFi calling is turned on, but the cellular bars are still on. On the last Samsung phone i owned, the cellular bars were kind of disabled and it only showed the WiFi bars.
Is this how it loooks for you guys?
Same here, the bars never go grey........I thought this might result from the wonders of smartswitch allowing you to pick your call where wifi falls away however even disabling it doesnt change the colour!! Do you think that this means the cellular radio is actually still active or is just a little bit of superficial window-dressing that T-mobile will change with an update?!
As long as you see the handset/with the wifi symbol above, means you are using wifi calling. That goes away when it switches to cell tower calling. If you prefer wifi calling, then make your setting as the image below.
If u put like picture you will have wifi calling fully and not be using network if you put on the middle it will show like urs wifi calling amd also using network meaning it will show the bars
I have no doubt i am using WiFi calling.
BUT, i think the question still stands, why is the mobile network still on? And is there a way to turn it off?
On my S5 it would turn off. As a result, i assume battery life increased.

I have a weird issue with wifi calling..
If I have it turned on, and I leave the house, I have no access to my data network as I travel around my area; I think the issue is that its always looking for wifi networks, and there are so many of them around me, including xfinity hot spots that are transmitting from people's homes, that I can't make phone calls easily.
Turning off wifi calling gets things back to normal, but I would like to leave "wifi calling preferred" on all the time, but it doesnt seem to be working properly..
This is in Chicagoland, where we have VOLTE, and all the "newest" Tmobile stuff active.
Anyone else notice this?
The bars are on because the Note 4 is a dual-mode device and can stay connected to both IWLAN (WiFi Calling) and cellular networks simultaneously so you can do seamless handoff from one to the other (VoLTE only). This is in contrast to previous Samsung phones that could only do one or the other. This is perfectly normal behavior.

Yeah, the only other phone that does it on T-Mobile is the iPhone 6. I actually love this feature cause often time I'll be on a WiFi call and forget and then drive out from my home and the call would just drop.

Question Wifi <-> Mobile switching?

I have this strange issue that has been with me almost since the beginning. I haven't been able to trace when it happens, but it now seems almost 100% of the time.
I only have WiFi in the house (wifi6, if it matters). If I go out, I only have 4G (I left only 4G and disabled 5G). I have no data until I put the phone into airplane mode and back, or I disable and re-enable mobile data.
Same thing when I go back in the house: no data until I disable and re-enable WiFi.
I've disabled the option for 'always-on mobile data' or similar, it's quite a battery drain if there's no cell signal.
Seems like a very strange bug, I don't have this with any of my other phones.
So you have both WiFi and 4G enabled and they don't switch seamlessly?
Exactly. I always have to restart each one of them, usually by toggling airplane mode. Was wondering if anyone else ran into this issue.
Ok this really is strange. There are 2(!) different toggles to enable data switching between WiFi and 4G, but for me it works flawlessly without them! As soon as I get out of my home WiFi range, 4G kicks in, and when I get in range again, the phone connects to my WiFi...
Hi, i have this problem too but it's not always.
I have a wifi 6 router too.
I also have problems switching from wifi to 4g. Need to toggle airplane mode on/off. 5g deactivated. No wifi 6 here.
I always assumed my vpn is causing problems during the switch to 4g. But hearing others have the same problem i would assume its zenfone problem.
I never had any issues in this area with my ZF8. With the option to have cellular always on I could walk out of my WiFi zone during a video call and no drop or short pause would appear.
With this off the network need a few second to work, and some apps need to be refreshed/restarted to gain connection. Never needed to toggle connection for this to work.
Maybe a reset would be enough or check for updates.
Ah, exactly! It does not necesarily need a network restart, but some apps just lose connection for a while, which can be from a few seconds to >1h. Which is even more weird as the icons are showing full connectivity. I would go out of the house, do stuff, come back later and I would only get the notifications when I'm back inside the house.
Rarely I had the connection drop completely (no signal) when switching, but I haven't noticed this happening since the last update.
