Any way to lock onto 3g only and not hsdpa

I was wondering if there is a way to lock onto ONLY umts and not hsdpa? It can sometimes take forever to load web pages because it is constantly searching for hsdpa. I am also wondering if you might be able to get better battery life this way as well?

I don't think battery life is going to be different since it's still technically a 3G connection. But if it is really searching for HSDPA a lot then it -may- make a difference.
Are you on T-Mobile? It seems that I'm on HSDPA at all the times, pretty much.

switching between 3g and HSDPA is not the same as switching between EDGE and 3G
As the poster above says 3G and HSDPA are basically the same technology using the same frequencies so would not make much difference to battery life.
Dont forget that on the stock rom it always displays 3g anyway so you cant see if you are using HSDPA or not.
Also this phenomenon seems to vary as to what network you are on, mine mostly stays on H anyway.
From memory the early 3g handsets that did not support HSDPA topped out at about 300kbps, not sure if that translates to the 3g symbol not the n1 though. not sure if thats what you would want, as its not much faster than EDGE anyway? so you might as well force EDGE only and save battery life

changing bands 3g only
yes this is possible. Go to your phone dialer and enter the following: *#*#4636#*# .you will go to another screen, select phone, scroll down and there is a drop down box that shoud say wcdma preferred. Select wcdma only and that should give you 3g connectivity only. You can change back or select other settings from this screen. You can choose what works best for you in your area. It should slightly improve battery life, since it is no longer looking for other connections. If you have poor 3g service in your area, then you probably do not want to select wcdma only. I hope this helps. I have done this on my rooted n1 and a non rooted n1. As long as you only change this one one setting it shoud not harm your phone.

Good answer, but totally NOT what the OP was asking. He wants to know if there's a way to lock the phone to UMTS and not HSDPA... the answer to that is NO... because both are 3G, as someone else already alluded to.

Improving battery life

Has anyone tried this on Nexus One?
http://forum.xda-developers.com/showthread.php?t=670999
"GSM auto (PRL)" works on AT&T Nexus, I don't know if it improves the battery life over "WCDMA preferred"
***EDIT***
Looks like this process works by improving battery life when phone is idle. Here are the instructions from the first original post.
1) Goto dialer and dial *#*#4636#*#* (DO NOT press send)
wait a second and you will get the test menu.
2) In the test menu choose 'Phone Information'
3) scroll down and choose on the first drop down - GSM auto (PRL) (for high speed data) or GSM only (You may get 3g if not use GSM auto (PRL)) Don't know what PRL means, but GSM auto (PRL) allows High speed data HSDPA (it was previously on GSM/CDMA auto(PRL) I think.)
4) Back all the way out.
5) You might want to reboot, but I found the settings worked straight away.
Edit 3 - I don't take any responsibility for step 6 -
6) Try other settings on the dropdown if you are brave as I don't know the consequencies of using settings like "EvDo only" and "unknown" as they may be better depending on the way your provider provides information.
Edit 4 - can't seem to select the other settings like EvDo and unkown anyway.
Edit 3 - TBH - GSM auto (PRL) is working for me with HSDPA and I will try (PRL) instead of GSM auto (PRL) <- edit - previously it mistakenly said GSM only the CDMA and WCDMA settings later to see what other effects there are.

Results for HTC Hero:
Your results will vary depending on the rom, but it should improve battery performance - some have had better results than me using this.
GSM only <---- If you don't get 3g with this it is the same as 2g setting then use GSM auto (PRL) if you want faster than 2g (as some people are getting 3g on GSM only - I will investigate. (if you don't use internet or don't need fast internet)
5½ Hrs - lost 5% Battery - This one is same as running 2g as you don't get HSDPA, but using Opera browser makes browsing fast even using this. If you want Higher speed data use the one below.
GSM auto (PRL) <---- Recommended if you want High speed Internet and save battery
1:40am to 2:00pm (12hrs 20 mins) - lost 40% battery with moderate use a bit of surfing at HSDPA speeds, a few calls and messing with a few apps. Other people have had even better results than me though, so I might change my rom and try again. (I would usually about this amount of time I would have lost about 70-75% - and yes it was that ridiculous - I had to find something to stop this).
" WCDMA Only"
2:06pm to 11:37pm - (9hrs 31mins) lost 46% battery again moderate use and a reboot
This one might be useful if you live in a place that has low GSM signal like the chap in post #10 as it does give HSDPA - but this is only a suggestion as I cannot test it in Iceland. Anyway
" WCDMA preferred"
6:02am to 2:51pm - (8hr 49mins) lost 41% battery this time with less use that the WCDMA use and no reboots.

I'll give it a try

i read the first page, what exactly does "PRL" stand for? and isnt this just using GSM-only? how is it able to use gsm but then switch to HSDPA (3g) for data? i didnt think that was possible.

I have been doing that for a long time and I'm pretty sure it helps...
Just set it to WCDMA only and you are all set...

well I think this really might help. I changed it to gsm auto (PRL) and my phone still uses 3g and my battery only dropped 2% in an hour and 10 min. went from 86 to 84% which it used to drop like 6% in That same time period.
I have to do more testing though to really know for sure.

mine was on WCDMA preferred....will i lose anything by switching to GSM AUTO (PRL)?

Giving this a whirl. When I'm at home and at work I'm on wifi which, combined, is like 90% of the time the phone is running so not sure how much it will affect me, but lets see

you won't lose anything from my testing so far. full 3g still works and my data speeds are over 1.5 Mbps.
my theory is that this stops our phone from constantly searching for a roaming partner/network. if true ATT has no roaming agreements so who cares.

I had that problem too but i wasnt sure if it was just where i was

Just set to GSM AUTO (PRL) and reboot.
I downloaded two apps from the market and both downloaded faster than usual. Also the browser seems to load faster.
I'll report back with battery data.

It may be that this saves battery by using the PRL acquisition and system tables for allowed frequency + system lists, thus stopping the phone from searching all the time.
I've not had it on this setting very long so I can't really tell yet, but it looks encouraging so far...

i still am testing, but i have definitely noticed a MAJOR improvement so far. for example this morning my phoen has been off the charger for 4 hours, and i'm still above 90%. on normal days, my phone would have dropped much more than this.
and the battery voltage seems to be staying constant too. for example my batter was at 4040 mV, and i checked an hour later, and it was still at 4040 mV. this NEVER happened before, it would always drop some amount.
is it possible that this entire time our phones have been actively searching and updating the roaming list, but with this setting now its just locked on the home network and not searching anymore?

I can confirm that. My phone seems to use much less power while in standby mode and it just dropped from 99% to 89% in 7 hrs, with auto synching of Gmail, Facebook and other stuff, while in the last days I could experience drops of 10% in about 1.5/2 hrs. I'll keep testing this mode and will post back if I'll have something interesting to share
Thanks for sharing the trick mate!

exactly my usage pattern, and my battery used to drop the same amount as you.
i used to kill 10% in an hour EASILY, sometimes more if i used the phone hear and there. but now with this setting, i'm now at 7.5 hours, and way more than half battery left still. on normal days my battery would be dead in 6 hours sometimes. huge improvement.

i think the other thread said for CDMA users, you pick CDMA Auto (PRL). you should probably read the linked thread to be sure.

I didn't think there was a CDMA version of the Nexus out, just the two GSM versions.

well the CDMA option didn't do anything and gave me no service sadly.

Well, that's because you aren't on a CDMA carrier then. I checked and the Nexus One only comes in GSM. If this is a Nexus One you have, then you are have a GSM version, and are on a GSM carrier.
Um, surprise!

[Q] G2 High Cell Standby - Radio Issue?

So far I'm really happy with my G2!
I'm in Milwaukee where we have H+ coverage. I'm getting around 12hrs from the battery with moderate use. I don't think this is terrible, but the "cell standby" uses 40-60% of the battery!
I did some research and found the "WCDMA Only" setting. That brought the "time without signal" down to around 30% from around 60% but I don't like the idea that if I leave WCDMA coverage I'll miss calls etc...
So, my questions is - Is it possible that this is an issue with the radio firmware? It seems to be unnecessarily switching from EDGE to 3G/H+ since if I force WCDMA only, it maintains connection.
Any ideas?

I suggest you change your setting to WCDMA Preferred.
That, obviously, will cause the phone to connect to the faster network if it's available, and if it's not, will connect to the slower EDGE networks.
Having -50dB HSPA at school, and marginal HSPA at home, this works great for me.

Sometimes there will be a handover to 2G even if a 3G signal is reachable. Possible causes are sudden increases in utilization of the 3G by other users or attenuation for other reasons. Setting WCDMA-only prevents the radio from performing battery-draining tower searches, but like you said there is the problem of occasionally not having any coverage at all.
This is a problem with T-Mo US's network. You can see symptoms of it on other devices (particularly so with the Nexus One).

Open dialer and enter *#*#4636#*#*. It's in the first list item.
Edit: I see your location is Bay Area. I find that T-Mo 3.xG coverage is pretty lacking out on the edges of suburbia (think the hilly areas east of 680).

I have high Cell Standby as well. I checked it's details out and it claims that 50% of the time, my phone is without signal. Check this by going to:
Settings > About Phone > Battery Use > Cell Standby
It will tell me that 50% of the time, I do not have cell signal. I compared this to my brother's Vibrant and his is at 0% signal loss. Definitely something wrong here because my cell standby usage is twice as much as my brother's (we live in the same household so location shouldn't matter).

And how do you un-do this if it does not work out?
NM! I figured it out~!
Edit: figured out how to change this setting. But when I set it to WCDMA at my office I get 1 to no bars And the internet is slow. I do have a H and it is using HSPA.
If I set it to GSM only I get 3 to 4 bars, mostly 4 bars max. And then I am on Edge, and the internet is a bit faster.
I am just wondering why the coverage sucks so bad for 3g? When the maps I can find seem to show good coverage. When I am out and about I get good bars on HSPA, but inside it just sucks.
I am in Houston, area code 77009 :/

Thanks for this info

Weird, I just checked my G2 and I have 0% time w/o signal.
I live in Houston, TX and this is a combo of downtown and my house.
Botched setting in the phone?

i got 14+ hours the other day, but did notice that my cell standby has been very high.. when i checked... 44% of the time is without a signal (not sure how that's calculated) as I rarely ever see signal loss.. except for an hour out of the day I go into airplane mode at the gym because i have 0 cell coverage there. But I just changed to GSM Auto (PRL), i'll see if anything changes tommorow.

Why do you think this is a botched setting? This is exactly what it should be like. You don't want any signal loss.

Very interesting trick. Changed my settings from GSM only to WCDMA only. My "time without signal" dropped from 50% to around 35% so it helped a bit, but not completely. On top of that, I noticed that my signal was a lot weaker and would drop more frequently so I had to switch back to GSM only.

I meant on the OP's part.

I don't think it's a botched setting.
I just wonder if they have the phone is jumping between bands too frequently and unnecessarily. In my house the phone constantly jumps around from H-G-E suggesting that it's dropping signal and switching bands. However if I force it to WCDMA it never loses signal.

[Q] Option to use only 3G NOT HSPDA

HI all!
Right now I am using [Build][10.12.2010][NexusHD2-FRG83D V1.8 PPP+RMNET][Kernel: hastarin r8.5.3_oldcam] and that is quite ok for me.
However I havent found anywhere on that build an option to disable HDSPA speed.
What I would like is accept 3G but disable HSPDA. Now I only have a change to disable 3G totally and only get 2G. Basicly area where I live is keeping me a situation that phone is very often trying to connect HSPDA but then changes is 3G speed. It causes me time&battery drain.
I have found a solution to force phone only use 3G but that is what I wanted. 2G and 3G are ok but I want to disable HSPDA.
Anybody could help me?

Up, Up... anybody have same kind of need?

i also need same help regarding this, reason is my data plan only use 3g (umts) and not 3.5g (hsdpa)... but my android always switch 3g to hsdpa back and forth and drain battery much faster
is there any tweak/program/widget/application that can enable 3g (umts) only?
windows doenst have this problem cause in winmo i can switch the option easily (enable/disable hspa)... but android dont have this kind of thing

I have the same problem. I don't even have HSPDA where I live, yet it tries to connect, fails, and then connects to 3G. It's a very time consuming processor to wait for the phone to do this when I am just trying to load a website.

Yes.. maybe it will not drain much memory but.. who wouldn't want a fast internet..

Afaik Hsdpa uses the same radio towers (or whatever the name is) as Umts... just different software. so there should be no battery drain caused by this.

This mite help you
1. Go to your dialer
2. Dial *#*#INFO#*#*
3. Click 'Phone information'
4. Scroll down to the first dropdown selection and set according to your preference below...
For simplicity, there are two main types of cell carriers, GSM and CDMA.
The following popular data communication technology is associated with each cell carrier type:
GSM = GPRS (2g), EDGE(2g), UMTS(3g), WCDMA(3g), HSDPA(3g) {Cell Carrier examples: AT&T and T-Mobile}
CDMA = CDMA*(2/3g) EV-DO(3g) WiMax(3/4g) {Cell Carrier examples: Verizon and Sprint}
Now that the general stuff is out of the way, here's my take on the Preferred Network types:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

uhh... maybe you dont catch what us mean....
when umts change to hspda (icon change from 3g to H) then it use battery power.. in my case i use 3g (umts and not 3.5g or hspda )data plan only... but android keep searching hspda signal and THIS is when battery used the most (the process) and EVEN when my area have 3.5g covered but because i use 3g only data plan... then the back and forth process (3g<->H) will kep coming and rdrain my battery fast
so... we look for any kind of workaround so our android keep stay in 3g (umts) and not drain any unnecessary battery power searching for hspda
btw sorry for my english

i use this thing before and no luck
i use "wcdma only" as the option and android still process 3g and 3.5 back and forth, maybe android "thinks" 3g/umts and 3.5/hspda as the same?? android categorize umts and hspda as one big fat 3G network
i wonder why newer os like android doesnt have this kind of feature in winmo there is an option :
disable hspa = so hspda disabled.. AKA 2G or UMTS only
enable hspa = enabled hspda, hspa, hsupa etc.. AKA 2G, UMTS and HSPDA

try this settings
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.

isnt cdma auto (prl) used exclusively for cdma phones? (those phones with evdo and wimax thing) and not used for our hd2 (GSM)???

C'mon how this is impossible with newer phone software??
This feature has been in WinMo and Symbian in many years!!
It is really frustrating that almost every time my phone is trying to make HSPDA connect and then decide 3G is enough and possible. It causes some delay and sometimes also timed out errors.

agreed
my android keep going back and forth between umts 3G and hspda 3.5G like some clueless kid while 2 experienced guy (symbian & winmo) laugh at him

i know this is a old topic
i have still this issue
my phone is switching to hsdpa an back to 3g after a few seconds
when the phone is connected to my slow wifi connection everything works fine and i can use it for 3 day's
when it is connected to hsdpa my battery is empty after 15 hours and the voip connection is not working properly (i need to start a ping to some server first to keep the connection alive so i can call with voip)

I just came upon this thread, but I don't have this problem, so I can't really test it out this theory. But my thought was, what if you just went into the build.prop file and edited the ro.ril.hsxpa.category settting from ro.ril.hsxpa.category=2 to ro.ril.hsxpa.category=0. I just tested it out and it never jumped from 3g to H. My only concern is that you wouln't get the fastest speed you could be getting. Test it out and let me know though.

at this moment it is not posible to root my phone (SE Xperia pro with latest firmware)
so i am afraid we need to wait to test this
but thanks for the hint

Network coverage issues or device ?

I'm having some problems with my G2 - I don't have good 3G coverage especially inside and my phone keeps dropping calls when on 3G. It seems the software doesn't reconnect that fast and doesn't switch to 2G when the 3G signal is too low. Is there any way to change the preferred network and stop the device being so agressive at keeping 3G connection?

Settings/networks/tethering & networks/mobile networks/network mode/GSM only.

I already know that. It is the most unhelpful advice to give. I have to constantly go into settings and change that? No way. It isn't in the notification toggles which is really odd. Any idea how to add it? I feel my G2 has some radio issues.

Well if you're going to be like that then there's no wonder why there aren't a stream of responses on here with people trying to help you out.
Just remember, you're the one with the problem, so you may want to be a little nicer to those that try to give you help.

I'm sorry about that, but there wasn't a stream of responses in the first place. He was just stating the obvious, and the obvious is that the G2 doesn,t have a shortcut to switch between 2g and 3g. I'm just trying to figure out a way to do that, but all the apps that claim to do that and they are too many of them, just don't work. I'm thankful for any help, don't get me wrong.

There isn't a solution as simple as hitting a switch, but you can try the following:
Go into your Dialer and tap in *#*#4636#*#*
This will take you into the Testing Menu
Select 'Phone Information'
Then about half way down you will have a drop down where you can "Set preferred network type:"
This will allow you to choose whether to use 2G or 3G, but more important to your case you can choose how it will react if signal strength is low.
You probably want to select something like "GSM auto (PRL)"
Bare in mind though that this option will reset itself back to original setting each time you reboot the device.
Now I don't know if this will solve your problem, but it is worth testing out.
Here's a list detailing the main available options:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best.
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this
