There's a setting within advanced Wi-Fi settings on my note 10 plus that it's called switch to mobile data.
The setting essentially allows me to switch to mobile data if a Wi-Fi signal is low it essentially to my understanding switches between the two on its own depending on how weak or strong the signal is.
I currently have it turned off, but I am curious in regards to leaving it on for simplicity sake it makes things easier rather than always having to turn on and off Wi-Fi.
Has anyone used this setting and if so does the setting severely drain the battery life?
Any information to be greatly appreciated thank you.

It's going to drain a bit more in most circumstances. If you have a weak WiFi connection and a weak Mobile connection, it may be pretty substantial. Best bet is to try it and see how it goes.
If beeing connected all the time is important for you, the battery consumption should not be that high, depending on the signal strenght, but, if data is always on, data use is what precisely will go up

Hello everybody, I was wondering if anyone know of any ROM that allows to switch from 2g to 3g (or viceversa) automatically to some apps, like juicedefender, or extended controls. I think Cyanogenmod allows it, but I heard it doesn't provide a good energy administration.
And in the other hand, as I talked about energy administration, what ROM do you think works better for battery in DHD?
Thank you guys!
after all this time... nobody?
You can't toggle 2g/3g for some apps only, it's kinda global, for the entire system...
I think he means that it triggers the switch on some apps.

the switch between 2G and 3G has not direct relation to the type or form of application, it can only be manually selected by the user, this is the fact that in areas where 3G is unavaliable or weak, the phone may switch to 2G to ensure a stronger, more stable signal. keep in mind, mobile data (2G or 3G) also consume a relative part of your battery
I know that there is relative difference between 2G and 3G power consumption but the type of ROM and Kernel is a major part in determining the battery life. The current set up I use gives me approximately drain of 15% for 6 hours with approximately 30 txt and 10 minutes of call time all through 3G signals with the WIFI switched on. with a battery life like that, switching to 2G is relatively pointless. doubt it would save substantially.
I just transferred to the University of Minnesota,and it seems like T-Mobile has terrible coverage and penetration on campus; my average bars are lower, and my battery life has tanked, with battery stats telling me that the cell standby is taking 35-50%, with anywhere between 5-35% time without signal. I can only guess that the radio is sitting at max power trying to grab signal, but I may be wrong.
I've tried both the 26.08.04.30 radio, and the newest Bell one, both seeing terrible performance. I find myself needing my phone data, so I'd rather not slap on airplane mode or turn off 3G if I can help it. I was even considering tethering whenever I decide to get a laptop.
Anyone have any tips?
EDIT: A couple additions, fixes.

Does your school have WiFi pretty much everywhere? My university does, and I am on a newer Even More plan so I was able to get free WiFi calling (does not use minutes). WiFi saves battery especially when using data when compared to cellular data. Just make sure you set the WiFi sleep policy to never in Settings > Wireless > WiFi settings > Menu > Advanced
I've been attempting to use that as my solution, but it seems like there are plenty of areas with flaky wifi. I feel like that's going to make the radio work hard to try grabbing a good signal, in addition to Wifi Calling trying to enable if it drops. I'm seeing how it goes.

Wifi calling is your best bet, I use it on campus and in lecture halls all the time. If Tmobile has crappy service in the area there really isn't much you can do to change it. Sucks.

I See my wifi has used 30% of my battery but ive been on 3G all day, does it drain the battery searching for networks?
It does use some power when searching for networks. There is probably an APP or settings that you can change to set the Freq of checks maybe. Or you can just turn of the Wifi radio when you know your not going to use it.

Yes it uses a lot of power if its regularly searching for networks. Especially if you're moving around and seeing dozens of WiFi spots. Just turn off WiFi when not in use, simple as that.
A lot of custom ROMs have less aggressive Wifi seeking intervals. You can usually set it manually with ease too. Lots of apps out there if you don't want to do it manually.
All that was said is true, but still I find that 30% usage for Wifi just for searching nearby networks is a little too much...
Although I haven't got anything to compare with, I always turn wifi off if I'm not using it during long periods.
Regards
I turn wifi off when it is not needed and battery life goes from one to two days.

I've been using Tasker to turn wifi on at home/work and off when I'm elsewhere. It's using cell towers to determine location, so hopefully it won't impact the battery much.
I leave wifi on 24/7, today it has used 2% of the 60% battery i've used.
I travel through london so I assume it is constantly finding new wifi signals.

Y5 Battery Saver .. on the market, free. Turns on/off Wifi based on known networks and cells in the area of the AP.

I leave wifi on all the time as well, and I also only have used 2% of the 70-80% battery I used up already.
Try going into wifi settings, then advanced wifi settings, then turn off the new wifi network available notification option.
This increased my battery life slightly.

Y5 - Battery Saver helps out tremendously! I barely ever use more than 2% when home all day...although that may be a bug but I started a thread for that already.

That 30% displayed can be deceptive since it's based on the amount of battery discharged and not entire battery capacity.
Well wifi, when on is looking to connect to known networks. If the signal is weak it will disconnect and connect to another network near by if there is that has better signal. This process does use some battery. The biggest drain will occur when you are actively using wifi, that is when you download or upload. So the best way to save battery, is to close wifi when not needed. If however you want wifi you can set it to never sleep. This way even if the screen goes off wifi will be connected and your device wont use the 3G which is way more power hungry.
I think I remember an app it was called Tasker. Where it ( I believe ) used your location to set certain settings. True? If thats the case, couldn't I set it to change my internet to 3g when I get to work and wifi turn on when I get home? If it does use your location wouldnt that use more battery? Or is a simple toggle the best? Id like an automatic option if possible.
Battery usage depends on how it detects your location. GPS would me the most accurate and use the midst battery. Network is only accurate to a couple miles/km, but uses less battery. I use what cell tower I am connected to wish is more accurate than location, used less battery but can be less reliable as there can often be several towers you connect to, took me a few days to set them all. Also, if towers get upgraded, that can throw things off until you update your settings. I also had problems with wifi calling as that disconnects you from towers all together.
But yes, tasker is awesome.
Tasker and Locale do this, and much much more. Looking to just change networks, other apps like Juice Defender will do it too.
They of course will drain some battery because they need to use GPS and be running in the background to properly work. Of course you could choose to use network location but you won't get as good of performance as far as specific location services.

I have N7 LTE 4G and most of the time I use it with Wi-Fi only. Yesterday I decided to get a pre-paid Sim to use for Data only when I am in a place that doesn't have Wi-Fi with 1GB per month data for $2.90 (yes it is THAT cheap in Egypt ) but only 3G/HSDPA/HSPA+
Now the problem is, Cellular network is always running and battery drains fast even though I use the internet on Wi-Fi and turned Mobile Data off.
I've read that I can turn on 2G to save battery and disable the cellular signal and indeed when I check 2G, I get no bars in cellular top icon and it says No Service (Network Name) BUT..... as soon as I open internet browser or any internet app, the cellular network works again by itself although 2G is still checked !!
Is this some kind of bug ?
The only solution I can do is to turn on Airplane Mode and turn Wi-Fi on afterwards which is not ideal
Any help would be much appreciated.
There is an app called Battery Monitor Widget that has "Tests" tab when I press on it, it opens "Testing" page in which the first option is Tablet Info. There is a list called "GSM Only" in which there is a toggle to Turn Off Radio and indeed it turns it off
I use airplane mode then just turn wifi back on to keep the cellular radio off.

It really depends on your signal strength. If you have strong signal you shouldn't see a huge difference. If you have a weak signal then it could be a big boost to your battery life.
And I'm not sure why you said that it was "not ideal" in your initial post. That's really the best way to go about it.

Signal is always good but I don't even need it to be there when I am on Wi-Fi as the tablet has no GSM phone functionality.
I think there is something wrong elsewhere with the battery draining so fast other than the GSM Radio being On.
The battery was good and lasted 2 full days with moderate usage and Wi-Fi always On but it started draining fast when I left the tablet untill it totally discharged and woke up to find it powered off and then charged it till 100% and battery reached 55% in 10 hours with very light usage
It sounds like you have an app draining your battery in the background. Try installing Better Battery Stats and see what's using all your power.
