Disable 3G with a program.

I've been browsing through the forums a week ago and saw a post with a program that can disable/enable 3G permanently, only if you want to.
Since im going through tunnels alot and going in buildings that block 3g which makes the phone switch from 3g to g, which costs alot of battery power, i would love to have a program that disables the 3G function and only enables it when I want to.. I just cant find that post anymore..
Can anyone recall the programs name?

comm manager pro i beleive
that works on my 8525 dont hava touch pro yet to try

You already have it. It's the comm manager. Use advanced config to edit its functions and add 3G on/off

or use modaco nodata

Easy solution no additional software necessary
Navigate to start/settings/phone
under phone icon select band tab
under band change netowrk type from auto to GSM . Leave select gsm/umts on auto. click ok. all done about double the battery life i.m.o. , only using 3g when i need to

'Bands' tab and Advanced config questions

I've searched the forums for an answer to this and I've found partial answers. I'm hoping I can get a response that will work for me.
Firstly, in the 'Bands' tab, I'm looking for some clarification on the options available. Under 'network type' there is 'Auto', 'GSM', and 'WCDMA'. Auto, I understand. GSM I'm assuming means GSM network (T-Mo, AT&T and not CDMA). WCDMA, according to Wikipedia, is basically the network that allows 3G speeds over GSM networks.
Now, when I set the network to GSM, I get an EDGE icon in place of the 3G. When I set it to WCDMA, I get 3G, as well I should.
First question: If I set the network to WCDMA, will it force my Fuze to ONLY connect to 3G? Where I live, I'm finding it hard to find a 3G dead zone to test without traveling 30 miles...
Second question: Does forcing 3G only improve battery life? I read in one post there are separate radios for 3G and EDGE/GPRS (which makes sense as to how you're able to talk and use the data connection simultaneously) and by forcing one, the phone doesn't constantly scan for the other.
My third question has to deal with having my device automatically disconnect the data connection after it finishes its business. I read in several posts that 'Advanced Config' has an option to set the data timeout, but I've read through the menus several times and have seen no such option. Are there multiple versions of advanced config floating around? Barring that, could someone just tell me what registry entry to add/edit to set the timeout? I read in yet another post that the phone automatically disconnects after 30 minutes, but that doesn't seem to be the case, as I tested mine and we're going on over an hour with no connection drop. (No email is being checked and weather is disabled. Prior to me starting this particular data connection, the phone had been connectionless for almost 16 hours.)

AdvancedConfig/Menu/More settings/Connections.
There is also that option in DiamondTweak.
WCDMA means 3G only, which means that your phone isn't searching for GSM signal. I haven't noticed battery improvement when forcing 3G, although that would be logical.

[App Idea] GSM/WCDMA Switcher

Hey guys,
As the radio stack is the second cause of battery draining after the display, I was thinking about a way to save battery life by reducing the impact of the 3G connection. Most of the energy saving apps on the market are only disconnecting the phone from the APN, but this isn't a great solution as each app could be set to update at different times and thus being unable to download data even if the user sets some exceptions. So I thought that an application which operates in the following way could be great to save power:
- The phone uses the 3G network while the screen is on;
- It switches to 2G when phone is in standby mode;
- It disconnects the APN data connection while the phone is using a WiFi Network;
Obviously to avoid possible issues during the switch between 2G and 3G the following rules are applied:
- If there's an incoming call or a phone call is being performed, there won't be any radio switch until the phone call is ended;
- If there's an incoming SMS/MMS, there won't be any radio switch until the text message is fully received.
Unfortunately as I'm not a Java developer I can't code anything like this. But let me know what you guys think about my idea and if it's technically feasible... Maybe some developer could be interested into further exploring my thoughts and will try to create such an app
Cheers

I'm not a developer but I think it sounds like a great idea. I go into settings and switch it to 2g when I'm in spotty areas outside of town. I have to work a bit to keep my N1 battery alive all day...

Hello I'm new here.
I don't know if your suggested profiles are the best case scenarios. You would need to calculate your data throughput, not just the radio power.
If you need to send 100 packets, your radio would be on the longest for edge > 3g > wifi. So, even though wifi uses the most power, it would be for a much shorter duration.
A profile for "place calls only" would work somewhat like airplane mode, but still keep track of towers. Your phone just wouldn't register on the network unless you wanted to place a call. You would miss your incoming calls, have no data connection, or sms. But, you could have it check at an interval for voicemail or sms. This would be most useful for "ringer off" situations like class or meeting.

Afaik Android is always connected to the APN even if the phone is not downloading anything, consuming a lot of battery power. On other platforms, i.e. Windows Mobile, the connection can be terminated by user and re-established when an app needs that.
The amount of data downloaded by widgets, Google mobile applications or apps which operates in background like eBuddy or Facebook should be quite low, so downloading the required data by using GSM or WCDMA while the phone is in standby would be pretty much the same. The only difference is that downloading stuff using GSM/EDGE should take much less energy power.
So that's why I thought about the app I described before: the phone can save a lot of energy power while in standby and be back to its full horsepower when there is any kind of user intervention. Pretty much the same thing that the system already does for CPU usage. It scales to the less consuming protocol (or, in the case of CPU, frequency and voltage) to save power

I know on the google api it isn't possible to do this, but I don't think that isn't the problem.
At the moment you have 3 options. GSM only, WCDMA only and GSM/WCDMA. Whenever you switch between the 3 of them, the phone will lose signal for 10 seconds before it can find the best network. So the switcher here is not the best as you will lose connection, and what if you are downloading something at the same time...
What you need is when the phone is on GSM/WCDMA that it knows the best network to pick from depending on the phones lifecycle. GSM/WCDMA loses battery power because it always tries to find the best network to connect to, so for example if you are on GSM it will constantly try to find a 3G network etc (as far as I understand it).
What we need is the ability for the phone to stay on GSM when the phone is idle and then when the phone is woken up to automatically start to search for a WCDMA network and then gracefully switch over like it does now. For this I have no idea if it is possible as I don't know how the scanning of the network works. If it is possible then that would be wicked. But this is what we need.

my preference would be if the phone would stay on 3g as long as any possible even if there would be a more reliable 2g connection and only switch to 2g if there really is no way to connect to 3g. turn of apn if the screen us turned of for longer then 1 or 2 minutes and only check every 15 minutes or so.
most of the time I'm on 3g only mode . since I live in a city I got good coverage almost all over the city. only problem is that when there is no 3g available also my phone is unreachable. I don't really miss data connectivity when there is no 3g since 2g is so slow that I rather have no internet at all but not being sale to be called or texted is a major disadvantage...

[REQ] App for auto-swith 3g>2g

Hi all, I have a problem I hope you can help me solving.
In my house I have a light 3G signal and a good 2G signal. Anyway my provider (H3G) prefers 3G networks.
This is a problem because, if I do not remember to switch in 2G when I'm inside my house, I am unreachable or, while talking, my phone switches network (10-20 seconds silence).
I know, it should be so easy to switch in 2G mode hen I'm inside my house... but I often forget it.
So the question is: is there any application allowing me to automatically switch in 2G mode when I am connected to a particular cell?
I tried a lot of "Profile Switchers", they do work, but they cannot control 2G/3G toggle.
Do you know some SW able to do it?
Very tanks!

nobody can 'help me"?

just search "switch network" in the market

Tanks, but switch network is only manual shotcut

According to developers it's not possible to do this without root due to a limitation in the SDK.

Look up the application Tasker

Tanks man. Very interesting application. But unfortunately does not allow the switch network 3g>2G :-(

[SOLVED] 3G consumes more battery than LTE, how this happens?

Hello XDA Community!
When my new phone (Huawei P9 Lite Mini) is on 3G/2G auto network mode, it consumes more battery than LTE/3G/2G auto mode even mobile data off.
I do not understand how this happens? For example, while 3G consumption at overnight is %10-15; LTE is only %2-3. This problem is the same in daytime too. Mobile data is off, unneccesary services/apps disabled, and no extra application installed while this happens. I tried all "wipe/factory reset/update firmware/factory reset/wipe/no app install" procedures, enabling all battery saving options, but it did not work. This is a problem for me when I'm in non-LTE areas.
This problem occurs the same result in different locations. There was no problem with my previous phone and I use same nano sim card.
I tried the following but it did not work:
- Wipe cache, factory reset, wipe cache,
- Wipe data/factory reset over recovery menu,
- Update latest firmware, wipe data etc. again.
How this happens and where am I doing wrong? Thank you for your help, best regards!
EDIT: PROBLEM SOLVED!
I changed my mobile carrier (provider) and the problem is gone. This is very interesting! I worked for hours and days to solve the problem, but this problem is neither caused by the phone nor by the software...

WCDMA (aka 3G with support for 2G/Edge) is in always-on mode on most phones, because that's how you receive and emit phone calls and, for most phones, SMS (in some more recent phones, LTE takes care of sending and receiving SMS/MMS), so if you're in an area where 3G/2G reception is poor, your phone has trouble locking on a cell with enough power to maintain contact, hence the battery drain.
4G/LTE only works for data, and voice if you have VoLTE (Voice over LTE) enabled, but works on a on-demand mode, even with cellular data constantly enabled. In other words, the 4G modem on your phone will memorize the latest position and IP address the nearest 4G tower/cell allocated it, and connect to it using the memorized settings when you need it to.
Not so with 3G, where DHCP doesn't exist, at least not the way it does in 4G: it uses PPP (Point-to-Point Protocol), where an ad-hoc IP address is attributed to each new connection, based on a pool of existing addresses allocated to the tower and its owner (carrier) by the authorities.

Thank you for your reply!
When I googled about 3G vs. LTE battery consumption, everyone says that LTE will consume more batteries. That's make sense on first thought. So what I've been through is very interesting to me.
I think about is there a problem with my phone's 3G antenna. (footnote: I don't know about that 3g and LTE antennas are same or seperate?)
But I understand that you say this is normal, right?
Edit: I found a forum that this problem may be due to the operator (carrier). I'm still investigating...

3G and 4G operate on basically the same principle: receiving and sending "information" via radio waves.
The difference lies in the frequencies each standard uses, the way the data sent over them is modulated and demodulated, and how handsets make and maintain connection, so if you stay in the same location, and set your phone to 3G-only, then switch Airplane mode on then off, it'll take your phone longer to reconnect to the 3G cell/tower with the strongest signal (not necessarily the closest to you), because it'll have to go through the whole getting-acquainted process again, whereas in 4G, it'll go straight to the "Hey, how do you do? Long time, no see".
Now, if your phone antenna has a problem, you could be standing a few feet from the tower, in line of sight, and still get a crappy to non-existent signal. How many bars are showing on your screen is just an indication of how well your phone is receiving the signal from the tower; it doesn't mean that this signal is consistent and steady, hence the bars coming and going in real time.
If I were you, I'd download and install the Hidden Settings app from the Play Store, and run it; there, you go to RadioInfo, and you'll get a lot of information about how your phone modem actually works. It's a bit technical, but it would give you an indication.

I will try and looking for a new carrier. Thank you again. See you.

I changed my mobile carrier (provider) and the problem is gone. This is very interesting! I worked for hours and days to solve the problem, but this problem is neither caused by the phone nor by the software...
