is there a widget that can turn off HSPA+ so i can only use 3G or even 2G network speeds? trying to save battery life.
thanks!

As we all know, Galaxy S has major issues with the battery life, one of the biggest hogs being the HSDPA data connection. From my experience, HSDPA drains 5-10% per hour in standby on my Galaxy S, while the WiFi connection drains almost nothing during a 3 hours standby. So I was wondering why doesn't Samsung thought of replacing the HSDPA with 3G or even 2G (GPRS/EDGE) while the display is off? HSDPA should be active only when the connection is used by the user and not the background services like gmail sync. Push mail notifications work with slow connections like GPRS so why not give the battery a rest? Do I have a point and if I do, is there a solution?
on my phone HSPA is only on when I use data. It switches to UMTS (3G) when idle. My provider doesn't have any legacy GSM/EDGE network.
Yeah it would have to be a bit more configured than that, with screen off and data idle - for example I stream internet radio and constantly have the screen off, with 3G only speed there wouldn't be enough overhead for it to stream consistently.
Just turn data network mode off on the power menu? Puts the phone to 2g for voice and text....

Mine doesn't work this way. After leaving the phone idle for at least 30 min, when I turn it on, the H is already active. I dont think it switches so fast from 3G to HSDPA. I'll monitor it for a couple of days to see if it falls back to 3G in sleep mode.
Turning the data connection off isn't a solution, at least for me. I want the background sync to work, but not on high speed, because it drains the battery faster.
That's a nice idea indeed. Practically, however, I have 2g all the time and a widget to enable 3g/h when required for browsing etc.
Thats a really good idea. I have tried looking for a widget that switches 2g 3g but can only find widgets that provide a shortcut. Maybe some day...

Running a N4 in the states on T-Mobile.
For Tasker, I have a few network connection types I can choose:
4G/3G HSPA/3G/2G
I'm trying to figure out what these actually are. From the wiki page it seems 3G and 4G share the same tech.
So, when my phone says H, is that the same as 4G? Or is it 3G HSPA?
Is 3G on the phone real 3G?
E=2G, right?
I upgraded my phone a couple of days ago and only noticed today there's no way of turning off 3G which is something new with Kit Kat.
In all iterations of Jelly Bean I could select 2G or 3G which was useful as most of Lincolnshire UK is rural and has a just about usable 2G network and 3G is practically no existent apart from in the large towns and cities.
What I noticed with Jelly Bean was that if I left it on 3G all the time it would kill the battery but leaving it on 2G improved the battery greatly.
Given now that Goggle have either decided that everyone has access to a 3G network and doesn't need the 2G switch anymore or have greatly improved the battery management when 3G is selected leaves me with a potential problem with battery life.
I will know over the next few days if the battery is still draining more quickly than previously when 2G was selected but in the meantime does any one know a way of switching of the 3G and only selecting 2G?
Thanks

I noticed this too and you are right staying on 2g will improve battery. You could install an app like tasker which will allow you to change to 2g, search the play store for 2g switchers or you could install a custom ROM like cataclysm which has a 2g/3g quick tile

How about the old classic. *#*#4636#*#* select phone info then choose gsm only.

you can choose 2G in Network mode in Wireless & Network settings

No you can't, it shows 3G only with no option for 2G selection.

Are you using stock KitKat 4.4 ROM? I am using PSX KitKat ROM and it has 2G and 3G in Network Mode. You might want to flash the custom ROM for the options.
Or just use the dialer code I posted...

I go from 4g to 3g frequently, even when my phone hasn't moved.
Actual LTE network performance is great at my location, I just can't stay connected constantly.
Toggling air plane mode while on 3g will put me back on LTE.
Is there a setting that I can change to make my phone stay connected to 4g LTE longer when I have a weaker signal?
Or even a way to only use LTE?

I have discovered that my MXP consumes more battery than it needs to over night. This is because, on my night stand, I have strong 3G signal, but weak 4G signal and the phone hangs on to the weak 4G signal consuming unnecessary power, even though I have good WiFi too. If I manually select my 'Preferred network type' to 3G in settings at night, this works, but I can't automate the process of setting 3G or 4G modes.
I discovered the "test mode" (dial #*#*4636*#*# on the phone keypad) and the Phone information section allows you set many more options via the Set preferred network type drop down. I'm unclear what the different options option will achieve. I want the phone to prefer 3G over 4G when the signal is poor. Is there an option for this?
Phone is stock, unrooted, on the EE network in the UK
3G = WCDMA
WCDMA PREFERRED (prefer 3G)
WCDMA ONLY (it will turn off you 4G and 2G.)
thing is if the phone shows it is hanging on to a weak 4g signal you have to remember just because it is displaying a weak signal it is still connected to the stronger 3g signal, it has to be otherwise you wouldn't get calls and texts.
Will have to experiment, but
> WCDMA PREFERRED (prefer 3G)
Does this mean it won't connect to 4G at all if 3G is available?
> if the phone shows it is hanging on to a weak 4g signal you have to remember just because it is displaying a weak signal it is still connected to the stronger 3g signal
Maybe, but my issue is the power consumption when connected to a weak 4G signal
Silly thing is it's not necessary to maintain a connection to 4G at all when WiFi is active, when the only useful benefit of 4G is fast data
If a phone is connected to a weak signal, it will take greater toll on battery.
Try - settings, more, mobile networks and then preferred network type. You can then set 3g?

I want the phone to automatically prefer 3G over 4G when the 4G signal is poor. Doesn't look like this is possible, and I'm stuck with aggressive 'hanging on to' 4G despite heavy power consumption.
