I'm not sure if this belongs in the pixel 3a forum or a Sprint forum, but I'm trying to figure out an issue I'm having. I live in a poor service area, so when I am home I use wifi calling. In order to reduce the poor service area battery drain, I turn airplane mode on. However, even with airplane mode, I am getting mobile network standby battery drain when I have wifi calling enabled.
I downloaded the GSAM app to investigate this further. When, I am in airplane mode and have wifi calling enabled, the phone radio clock in the GSAM app is on, however if wifi calling is off (actual wifi is still on) the phone radio clock is off.
Is this normal? Would anyone be willing to test this out on their phone? Thanks!
In Developer Options>Networking do you have Mobile Data Always Active turned on?

I know this is a stupid question, and I'm actually embarrassed that it's my first.. but, does 4G get turned off automatically when I connect to a WiFi network? I know it maintains a connection to the data network for other services, but what about 4G specifically?
I think I answered my own question.. In the Phone Status info page the "mobile network state" DOES toggle between connected/disconnected based on my wifi status.
Not fully, or servcies such as mms would not work. However you can enable this to happen through Juice Defender, and possibly other applications as well. I fully disable network data with wifi connected through juice defender, only drawback I see is unable to send/rec mms untill you disable wifi, allowing the network connection to estblish itself again.
edit: This is only for the data network portion, voice services can and will still carry over the 4g conenction which is just enhanced 3g
Does it go to a state that uses less power than the "usual" network mode? I'm looking for ways to conserve power while maintaining full functionality. Using Llama and JuiceDefender right now also.
Juice Defender can disable the data portion of the network which saves battery when connected with wifi. In the on the "About" screen in Juice Defender scroll down, there will be an option that says "disable on wifi" under which you can select to disable the network data
G'day all...
I have a TF101G and I have noticed that the mobile broadband seens to be consistently at the top of the battery usage list even when I have mobile data disabled and (get this) even when I have the SIM card removed.
My TF101G spends most of its life within WiFi range and I only need the 3G when it's out of the house.
Does anyone have any idea how to disable the mobile broadband transmission? Maybe I'm mistaken, but it seems dumb that it's still using battery to check in even when I tell it not to use the 3G.
Thanks,
Alex.
How have you disabled it?
I've seen many widgets/apps that say they're capable of disabling APN connections but the only thing they do is modify the APN connection name, so the 3G is still active but it never connects due to APN's changed name. The problem is that since 3G is not disabled at all, it might still use battery.
If you disabled from System > Wireless and Network > Mobile Network > Use packed data then 3G is turned off for sure. Also any system app that could manage that should be able to enable/disable that option.
Thanks for the reply.
I did actually try changing the APN as well as removing the SIM card. I still see continuous battery usage for Mobile standby at the top of my usage graphs in Aplications > Battery use.
I don't actually have the "Use packed data" option under System > Wireless and Network > Mobile Network - I only have Data enabled, Data roaming, Access Point Names, Use only 2G networks and Network operators.
I can always to to flight mode for no connectivity, but I can't for the life of me figure out how I can make the TF101G WiFi-only. Surely there must be some way of doing it. Maybe the forthcoming ICS update will fix it - we live in hope.

Sorry, I was refering to "Data enabled". If "Data enabled" is toggled, 3g is enabled despite the APN name's. Maybe you could try to disable "Data enabled" and see if it doesn't consume more battery.
First thing I tried!
No joy there.
Problem solved.

It's simply a matter of putting it in flight mode and then manually enabling WiFi. It works a treat!
I have now TW 9.2.2.4 FW and still if i do flightmode and then wifi on, i see cell standy as the biggest power consumer . to me it seems somehow the modem hardware is not properly switched off. anyone knows what modem chipset it is? or what could be the reason why this behavior?
If i do reboot with 3G modem off (so flightmode but with WiFi on), i get 'cell standby' as big power consumer after few hours. But reboot with 3G on (but no mobile data enabled) and also WiFi connected, then goingto flightmode + WiFi does not show 'cell standby' in battery chart . I had many problems and reboots with first ICS {9.2.2.3}, hopefully now i can get long and controlled battery life and no empty battery beeps in middle of night.
I was wondering should I disable the wifi calling feature(from the Setting>Application menu) if i'm in an area with good reception even when I use wifi often? Would it save more battery keeping it on or turning it off?
I need to know how can I turn off cellular services when I am using Wifi the reason i want to do that is because i believe that will increase my battery life.
I have an optimus 2x which I am not using so it does not have SIM in it but its on and on Wifi and with light usage I am 57% of battery life remaining for usage of 2 days and 7 hours I believe with cellular services turned off it will increase battery life
any help how it can be done
Just remove the sim card, you might have an option in settings > mobile / Wifi
Im not that familiar with the GN10.1 yet.
Turn on "Airplane Mode", and then turn WiFi back on. That will turn off the cell radio.
T-mobile S7 edge.
This doesn't always happens, but it happens often enough that it's beginning to get frustrating. When I'm connected to WiFi for long periods of time (at work/home), then leave to an area that has full LTE coverage, the s7 edge will not connect. I get the signal bars, they're usually always full, but no '4G LTE' logo. If I open any app/browser, it claims it's not connected to the interwebz. If I put it into airplane mode, then come back out, it'll grab full 4G LTE again and work fine.
Not sure if I have some settings screwed up or if i'm overlooking something... or maybe it's just a bug.
