In cm7 When i select wcdma only and activate 2g Internet plan... The network directly switches to gsm... In stock rom if u hav 2g data pack and use wcdma network then the icon remains as H(hsdpa) but 2g speed as its a 2g data plan and it remains on 3g network . In cm7 if i do the same the icon shows as E(edge).. Why can't i get 3g network on cm7?

Hello folks!
okay, the facts are: Im in very good 3g reception zone, MIUI 1.6.6 with default kernel, .08 radio, data on, wifi off.
Problem is poor battery life when 3G is enabled. Also, when using mobile data the H icon appears and data moves in and out, but sometimes the H icon just disappears and i get network error? I've tried numerous radio/kernel/rom combinations.
When i put airplanemode on, the battery consumption is constant 2mA (currentwidget). With 2G networks only, its 3-6mA. When 3G enabled, mostly the consumption is 20-40mA and sometimes like 10 times in day with minute interval of refreshing i get 8mA readigs. Any app to check if there is some syncing going on? I use only beautyful widgets weather widget, which updates itself hourly. And the normal contacts and calendar sync on. Fellow MIUI users have much lower consumption, a mate of mine gets 2-4mA when 3g enabled.
3g mobile network is one the battery killers. The h icon stands for hsdpa. This the fastest network but the network coverage is not that good yet (except for big cities). Switch network to 2g network (mobile off). If you really need mobile network, switch on 3g. Otherwise stay with 2g. There's imho no sense in using 3g without needing/using mobile network.

I tried using BatteryFu and APNdroid to get rid of my 3G while screen off. But that combination didnt work so well, sometimes it didnt disable my 3g and sometimes it wouldnt reconnect to 3G when unlocked. Any good programs to manage this?
I also wonder, I never cant download anything when 3G icon is appearing in statusbar. Its normally 3G but when I want to use the internet, it changes to H. Why cant I use the 3G network then? Im also having problems when the H goes to 3G the internet connection is lost. For example in market i get network error. The H wont stay there if there is no traffic for few secs.
Configured apn correctly? If you are not sure, do it again. Furthermore, you could try these settings for mobile network:
Uncheck data enabled and set network to 2g/gsm (depending on what you have). When you need mobile network, switch to "wcmda + gsm (automatically)" (name could be a litte different, translated it from germany) and check data enabled. I do it so and it's working fine.

Okay didnt understand very well what u ment by the last part of ur message
APN configured correctly? I have carrier default APN settings which have been working just fine for a year. If u ment APNdroid i didnt do much configuring with it. Gotta give it another try.
Last idea: flash latest radio.
No warranty for any damage.
When my phone connect a 3G network, it seems on roaming (R symbol) and it disconnect from internet. But actually it's not in roaming. My rom is Runnymede AIO 2.5 (snq kernel). What can I do?
what do you mean with "actually"? Either you are in a different country (roaming) or not. Check if you configured APN settings correctly.
I'm not in different country. There is no problem with any kernel except snq. APN settings are same as before...
Happens this only with 3G or also with 2G network?

Only with 3G (WCDMA) networks...
I was wondering how one switches from 4g to 3g(which i think people here call edge) to save battery.
I dont see it anywhere in settings so i wasnt sure what people did..
Thanks!
I think you mean 3g to 2g. This phone does not have "4g". It's just 3g with higher throughput.
I'm not sure if you can on the stock rom without a USSD code. But on custom roms it's:
Settings
Wireless and network
Mobile networks
Network mode
GSM only.
Unfortunately apps like llama/JuiceDefender can't do it automatically when you're on WiFi or not using data because Google "blocked" it. I think CM7 allows apps to control 2g/3g toggle though.
I thought if your wifi was on the 4g was turned off.
Also, on stock 2.5.- the system folder for wireless settings has a choice to only use the edge frequency. I don't know for any of the modded roms or the newer stock 2.6.- versions. Hope this helped.
T-Mobile uses 3.5g(which they call it 4g) a more advance 3g speeds so a with a 4g/3g toggle wouldn't do any good unless you wanna go to edge/2g. is not like Verizon where I think you have your Band for 2g/3g and a separate Band for 4g so what the toggle does its just turn off the 4g Band and automatically goes to 3g. but with Tmobile your have your Bands for 1g/2g and another band for 3g/3.5g(fake 4g) so using a toggle you would only be blocking 3g.
Hello everyone at XDA
I have an Xperia Play r800a (Rogers Canada)
I was looking in the menus and I remember reading somewhere that if I change the Network prefrences I can get better battery life.
So I was wondering out of these options under Settings> Wireless & Networks> Mobile Networks> Network Prefrences
I have these 4 options
GSM/WCDMA (auto mode)
WCDMA only
GSM only
GSM/WCDMA (WCDMA preferred
What settings should I choose to increase battery life? Also I almost never use mobile data since I am always near wifi.
if you dont use data really just use the data toggle to turn it off till you need it(Way way more battery life)
or if your like me and always need a little data present for google voice and and 4g every once in a while when actually using net then Gsm(= 2g and increded battery life over but 4g connection by couple hours) but alot slower than 4g
then just 4g when you need it (3/4g=wcdma)
auto just choses strongest signal no preference
and Wcdma perfed is just that if both signal available it uses wcdma but if not then then gsm
so for you if no data ever hardly and no constant connection needed then
wcdma perfered and a data toggle by ether a theme with notification toggles or the data switch widget or widgetsoid
hope i helped
Do you know which one would have been the default?
So from what I understand GSM only and data off gets me the best battery life?
For my phone GSM/WCDMA (WCDMA preferred) is default option.
And yes, GSM only and data off gives you the best battery.
I have a serious problem guys...i cannot connect to 2G networks..!!Whenever i change to 2G network manually..It says "cannot connect to selected network"..n automatically connects to 3G network..!!well 3G network is good but at some places only 3G networks are not available...so Can anyone suggest the solution to this problem??...tried all basebands versions...Custom roms..but no luck at all..
is it problem with hardware???
