Hi, is it possible to receive MMS messages on 2G network ? (by disabling 3G/ 3g+) ?
So actually, my question is : what do i miss if i set my network to be 2G instead of 3G ?
I ask this to optimize my phone battery use...
thanks
Nico
Yep - you can receive MMS on 2G network. (well at least on 2.5G using GPRS)
By using 2G network you will find that browsing is going to be slower. You will probably find the network strength is better and because you phone isn't searching for a network all the time you will have better batery life.
oki and what about google mails ?
Google mail will work but downloading of emails will be slightly slower on 2G than it would on 3G.

ok
thank you for all those information. I'll now switch my phone back to 2G, in order to improve my battery stats. Then I will use 3G only when I need Internet.
Bye

That is pretty much what I do because I find the 2G signal to be a lot stronger and it really seems to help improve the battery life.

Hi all. I was wondering whether anyone had any tricks to stop the PDA from using HSDPA unnecessarily. I find if I'm logged onto MSN all day, with just UTMS the battery would last probably 12 hours or so, but if I enable HSDPA it would clean out the battery in less than 5 hours.
MSN can't possibly require that much bandwidth. Is it possible to limit the phone from changing to HSDPA unless the bandwidth is actually required (i.e. when I connect my laptop to if for internet)
I use a dopod d810 in Australia with optus.
Thanks.

If you don't need 3G, switch the phone to GSM, which would use EDGE/GPRS, or use tools such as bandswitch etc. If you want to completely stopped data connecting by itself, try nodata.

Also, with some service provider, if the phone is connected to HSDPA, my incoming calls get sent to voicemail. If it is in normal 3G mode the call comes through. This has been a problem in many areas. As the last poster pointed out, Bandswitch can disable HSDPA so that 3G is the default mode. Since I don't have an unlimited data plan, I just change the band to GSM and use Edge unless I have to download big web pages or use the Video phone, then I switch to WCDMA mode.
Problem is, I use WCDMA all the time. I connect my laptop to the internet through my PDA. At these times the HSDPA is greatly valued. However, when I'm not and just want MSN messenger on my PDA, well, its a great battery drainer for no good reason.
At the moment I'm getting around this by turning HSDPA back on when I use the laptop and then off again when I don't so it just uses UTMS. However this is pretty annoying having to reset it every time.
Does bandswitching between GPRS and HSDPA require reset?
My carrier - 'MY MAXIS' is somewhat smart. They usually kick you out of HSDPA Network whenever you are not consuming large amount of bandwidth. The phone automatically switches to 3G , but then you are still connected. Then it will switch back to HSDPA whenever there is a sudden burst of data or so. Smart way of conserving HSDPA slots.
I don't think you can limit HSDPA bandwidth or so. Once its connected , its connected. It has nothing got to do with battery. Its just the power consumption. You have no choice but to disable the HSDPA module , so that it does not drain the battery a lot. Limiting bandwidth does not work. HSDPA/UMTS drains a lot of power.
Mine does that too... drop down from HSDPA to UTMS. But the difference between having HSDPA enabled and disabled in terms of battery life is like a third.
Its because if you enable it. It connects to HSDPA , hence it uses up more battery power. HSDPA loves to drain your battery life. This is why , you should switch to EDGE/GPRS whenever you are in mobile and switch it back to 3G whenever you wish to use it as a modem. You dont have any other choices ,mate !
Hey,
I've recently got my DHD. Although i still have that call drops like i had it with my HTC Hero.
At home we have a bad 3G signal. That's why i set my DHD to GSM Auto (PRL).
It still uses 3G and there are no more than 2bars (signal strength). However i also see my DHD on 3G with no bar (signal strength).
Sometimes when i make a call (1 of 5-10Calls) the phone starts on 3g, after some time it hands over to 2g and the call is dropped.
Do you know is the call drop at 3g to 2g handover the providers fault or is it the handset?
My best solution would be to adjust the GSM Auto (PRL)-3G-Treshold , so it would require a better 3G signal and would'nt switch to 3g at home at all. Is this possible?
Another solution would be if i make a call, phone should switch to 2g automatically. Seems more realistic!?
If those ways are not possible i can just use the workaround to use WIFI at home and use "toggle 2g if wifi"
Thanks in advance!
Have you tried to fix it to GSM only without PRL? This is how I've gotten rid of my phonecall dropouts on 3G.

Ya ofc, but the coverage is only bad at home.
That means once i leave home i want to use 3G.
Switching everytime i leave home is no solution.
But thanks anyway!
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.
Is it possible that the iphone 5 has better 3g reception than our arc(s)?
This is especially noticeable indoor, my friends iphone 5 can download at 800kbps where my arc has difficulties even connecting with the 3g network on the exact location and time and carrier, so it forces me to download over 2g and even this is slower than average(5 kbps).
Also when in settings i choose (3g(preferred) / 2g) my phone is a lot of the time without signal, so the switch to 2g isn't working that good. Often calls from friends are directed immediately to voicemail. Sometimes when my phones comes out of standby, then it connects to 2g, so the rest of the time it was constantly without signal.... frustrating! That's why I put it most of the time on 2g only.
Yes i've got the correct carrier apn settings. (outdoor my 3g can download @ > 1500kpbs)
same issue on different basebands, first on 77 now on 83, no difference there.
not rom related: first on jj'shybrid now on uhd 2.0.3 (locked BL).
Someone with the same issue?
You know what will be a good solution if the setting would be "2g(preffered) / 3g", so only when mobile data is switched on and a decent 3g connection is found it would switch to 3g and the rest of the time it would stay on 2g. This is probably kernel related, but does custom kernels have this feature?
Thanks
Yes. Lol

iPhone might have stronger antenna than Xperia phones.
ROMs have nothing to do with it. If your phone is rooted, you could try using some 3G improvement tweaks.
Is there any way (app or otherwise) to disable 3g but keep on lte? When I'm at work (a lot) I would rather have the option to use just those 2 but no 3g . Is there any way this is possible? I'm on slimkat so this might be a question to ask in the general android, but I never get answers when I ask there, so I"m trying here.
whenever I go from 3g to 2g it drops signal for a second and drops calls, but when going from lte to 2g it doesn't (and without 3g the calls should default to 2g and I wouldn't drop them on campus) so if anyone knows why the signal drops that could also solve my problem
