I have the Wifi enabled on my Droid Charge so when I'm home it will use the Wifi. But when using the Wifi the 'mobile data' icon is still highlighted in the pull down tasks..
now is it trying to use BOTH the wifi AND the mobile data at the same time? I want to use ONLY wifi at home to help conserve battery usage.
then when I leave my house will it automatically turn wifi OFF and use only mobile data?
trying to keep the battery usuage as efficient as possible.
In theory thats how it's supposed to work.
hahahha in theory.. but does it actually do it?
and another thing.. in the Mobile Networks Settings.. under 'System Selection'.. you can choose either LTE Automatic or CDMA Mode... being I am ONLY in a 3g area and do NOT have 4g LTE in my area yet.. should I choose the setting for 'CDMA Mode' Will that save the battery? or does the phone try to switch from 4g to 3g...
Yes, that is how it works. If wifi is on, the phone will use wifi by default, regardless of what it is connected to for mobile data (4g, 3g, 1x). Check out http://myresolver.info from your browser to see your ip and dns server you're using.

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!
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
This may be a dumb question but is there a way to set up wifi and data to automatically toggle? As in, when wifi is available it uses wifi, but when its not it automatically switches to 3g/4g? When im home i like to use wifi, but then when I leave I lose it and usually forget to switch over to data, so I get no emails or updates on anything until I look at my phone.
Option 1: Leave wifi and data on all the time.
When a trusted wifi network is available and your phone is connected, your phone will not use data (you will see the data indicator automatically disappear even though it is enabled). When you are no longer connected to wifi, your phone will automatically bring the data connection back.
Exception: using apps (usually Verizon-specific) that require a mobile data connection will bring the 3g/4g radio out of dormancy.
Pro: automatic switching, no need for additional apps.
Con: leaving wifi on takes its toll on battery life.
Option 2: Download/Install Llama from the Market
After you teach the program what cell towers are where, you can define criterion (ie you physically leave or enter a defined area, a certain time, etc) to carry out specific actions, including changing volume, display brightness, toggling data connection, wifi connection, bluetooth, gps, etc.
Pro: automatic switching of most anything imaginable, saves battery life compared to leaving wifi on
Con: additional app running in background, occasional instances of bugs

wi-fi matic is the app you want, it auto toggles wifi on when you are on the same cell tower than is near your home, as soon as your cellular switches to your home cell towers it toggles wifi on, and when it's away from home cell towers it toggles wifi off, you can use it for multiple wifi networks as well, i travel for work so i dont have a work wifi but u could have it auto toggle on at work or home, its also extremely easy to use, far easier than any tasker program.
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.
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.
