My phone works fine but for whatever reason, there is no Mobile Network Signal display in the Battery settings. I have the c567 version on ATT, also rooted. Any ideas?

Ok I've got a few questions about the different network types and battery usage.
As far as I know there are 4 different possible scenarios:
3G mode active
3G mode active and connected to mobile data (3G/H showing in notification bar)
2G mode active
2G mode active and connected to mobile data (E or G showing in notification bar)
Currently I have settings default with "Use only 2G networks" unchecked, and "data enabled" unchecked. I have tasker made to automatically turn mobile data on whenever I open any app that may require it, and then turn it off after the app closes, or I can switch it on from the status bar power control.
This is because I assumed having it constantly activated would consume more power. Is this true? does it consume more power having data enabled even when no traffic is going through? If this wasn't the case, I might as well leave it enabled. However with my current system I could still be saving power because if I leave data on, traffic WOULD periodically be used for automatic sync and apps randomly using network and stuff.
The other thing I was wondering about is if there was any major difference in power consumption between 2G and 3G network modes with no mobile data connected. if 2G uses much less power, I could have it set on 2G by default then use tasker to switch to 3G and activate mobile data when opening any internet requiring app. Are there any other advantages of having 3G active over 2G other than mobile data transfer speeds?
Thanks for any help!
Imho your settings are good. Mobile network is one of the battery killlers, so not using (or better using it when you really it), is very good. You are right, 3g has a higher speed on mobile network. Whereas the 2g-network has a much better network coverage. And the permament switch between 2g and 3g drains the battery very fast, too (happens e.g. when you travel).
To sum it up: Use 2g and mobile network off. If you need to use mobile network, turn 3g and mobile network on. Are you done, turn them off again and switch back to 2g.
When you say mobile network, do you mean when an active data connection is enabled?
Because just by the name 'Mobile network", you can be connected to a mobile network for calling and texting etc. without being connected to mobile internet/data.
Is there a difference in call quality between 3G and 2G networks?
Also when toggling between forced 2G only and 3G there seems to be an inactivity period where the reception icon at the top shows like 'disconnected' like it cuts all network communications, then shortly connects again to the specified network type. This delay might be annoying when trying to get internet fast on apps that need it... might not be worth the power saving, if it is only minimal power saving

for the best battery duration, use GSM ONLY!
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 am new to the forums, so please go easy on me.
A quick back story....where I live, I have to use a Verizon Network Extender to make and receive calls & texts from home. VZW's Extender only works with 3G. Since the upgrade to 4.1.1, the mobile network menu only has choices of Global, LTE/CDMA and GSM.
Until yesterday, I have been using an app called Phone Info to manually set my mobile network to CDMA Auto (PRL) when I got home and it worked perfectly. Since the update, the Phone Info app no longer works and I cannot find an app that will allow me the same access to set my mobile network. I receive just enough of a 4G signal where I live that my phone will not auto switch to 3G. So now I have an expensive paperweight at home.
Can anyone point me to an app or tweak that could help me with this problem?
Thanks in advance.
Hello,
after the last Droid Ultra Update to 4.4.4 I've started having this weird behavior. I'm a T-Mobile, locked bootloader.
When I'm connected to a WiFi network, the phone status bars shows signal strenght + the LTE or HSDPA symbols
When I'm NOT connect to a WiFi network the LTE or H(SDPA) icon goes away... I can do phone calls but mobile data is indeed disabled. I've double checked all the settings menu entries and data should be enabled - also the APN settings are fine ... even so the LTE/H icons appears only once I connect to WiFi.
It' driving me crazy.
Thanks.
When you turn on hotspot 4GLTE logo shows up, right? Unfortunate for everyone. It is some problem with the system which Verizon has populated the build.prop to disable the data outside of Verizon. Nothing could be done, as far as I could tell, until root is achieved (bootloader unlock).
Hi
is anybody is facing network issue in New Asus 6z
everytime network turned off and turned on automatically.
please help
I do not have any connection issues to the mobile network. Can you check at another location?
OP, try "Mobile data always active" in Developer settings. Also try "Reset Wi-Fi, mobile & Bluetooth".

I have some network problems too on my 2 days old Asus zenfone 6. The signal from mobile network is lost for few seconds and imediatly after the signal of wifi is lost. Does anyone have a solution for that?
No network issue as such.
But mobile network standby battery is twice that of screen battery consumption. Could be both are related
Yes, I am having network issues but I am not sure if its the phone issue or airtel network issues. So waiting to see if it fixes after few days.
I have network issues since updating to the 156 firmware. While having full 4g reception the phone switches to 3g for a few seconds without success and then 2g. It show full 2g reception but everything i try runs into a timeout. Switching to 3g only brings back full 3g connectivity most of the time, switching to flight mode and back does not help. Rebooting the phone does not help. If i just let the phone sit in 2g without a connection it "fixes" itself after 10-15 mins. This happens a few times a day. I have tried using different providers (tmobile and vodafone) but the problem remains.
