Is there any rom that can give you the 3g instead of the H signal? Do all rom kill your battery or is it just the one that I've decided to flash onto my phone?
lol wut!!!!!!
You don't need a new ROM for that. Just turn off HSDPA support on your device.
Start > Settings > All Settings > Connections > Advanced Network
Select "Disable" and reboot.
PS. Whether you get a 3G or H icon depends on your network. If you get an H icon, it just means your network supports HSDPA - the faster version of 3G network.
I find that I usually need to make some tweaks to get any ROM's battery life to an acceptable level. Advanced Config, included in most ROMs, is a great place to start.
Under "Power Management" in Advanced Config, set everything to the (Advised) option. Also, go to Menu>More Settings>Connections, and check the box that says "Disconnect after:" to something like 5 minutes, or whatever else you want it to be. That adds quite a bit of time to my battery life.

recently got my HTC Hero I am with Optus (Australia) all the time when it says 3G at the top of the screen the connection is terrible (speed tests are slow etc) however if that says H i get more bars and super fast connection
if i use just 2G its just plan slowand not usable for VOIP etc
I am wondering is there a command i set to say only use H which i am guessing HSDPA?
Thank you
OzJames
The phone automatically uses the best connection available to it.
If it's not showing H, you're not within range of HSDPA service.
check on the market and download an apps called "any cut".after u install it open it and create a short cut for phone info by tapping on create a shortcut then choose activity then phone info by scrolling down to the options that says phone info.now go back to the short cut created called phone info and open it and scoll down to set preffered network type.the phone has a default settings to wcdma preffered.tap on the pull down menu and choose wcdma only and press on the back key twice to go to the home screen .this keeps your connection on 3g or H but will reduce in areas you cant get 3g or H.WHEN YOU GET THESE CONNECTION PROBLEMS CHANGE IT TO GSM ONLY.hope this helps

I don't understand, what is the purpose of doing this?
Like I said above, the phone will always use the best connection available (unless you set it otherwise in the options). Why set it to WCDMA only?
If you're in range of HSDPA service, the phone will use it.
Maybe I'm missing something, but this makes as much sense to me as asking how you can download more RAM to your computer

actually it would be like setting the computer up that it would only use a fast internet connection, and if it is slow not to use it at all. would be like connection fast -> page loads, connection slow -> page is not loaded at all.
hs(d/u)pa is an extension to the umts standard. if it is not available in the cell you are using there is nothing to do about it. if you have gsm with edge availabe that might even be faster than a bad 3g/umts connection, but that depends on many factors.
Works perfectly thank you
Its much more stable now

Heya, I'm also on Optus in Australia. The problem thatyou have described is actually really common with Optus users. Optus has way too many customers and have overloaded their system. A easy work around for a more stable connection is to change your APN from internet to yesinternet hope this helps.
Check the thread pages to see results from other users who have had much better results than the ones I got.
This solution was discovered while I was checking out the CDMA Hero forum, so I don't take credit for discovering the method.
http://forum.xda-developers.com/showthread.php?t=651848&highlight=cell+standby
Goto dialer and dial *#*#4636#*#* (DO NOT press send) wait a second and you will get the test menu.
In the test menu choose 'Phone Information'
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))
Back out to test menu then back into 'Phone information' to see if it sticks (if not try again) then back all the way out.
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.
This way I managed to get 5½ hrs and only lose 10% battery (GSM Only)! (Edit 3-) Slightly more drain with GSM auto (PRL) but still better than before.
Previous to this I lost 35% in the same amount of time with the same use (sometimes even more when I didn't even use the phone all night).
Hope the devs can make use of this (maybe mess with other settings in there to improve battery more.). I did notice that the GSM auto (PRL) uses a bit more battery than GSM only, but that is to be expected.
Edit: Actually you might need to set it on each reboot, not sure, the settings stayed when I rebooted
Edit 2: When you change roms (or re-install a rom) you will need to do this again, but should stay after a normal reboot as it does for me.
============================
Results:
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.
=============================
Conclusion: (For me anyway)
SO my preference is GSM auto (PRL) some people have got some excellent results with this. You may, however, require one of the other options depending on your service provider signals.
===========================================
EXTRA OPTIONS :
Other settings you can change: (You may have tried this already)
If you don't get GSM auto (PRL) then if you press the menu button on your phone in the 'phone information' page and select 'radio band', you may be able to change it to Automatic or one of the other settings and then you might get GSM auto (PRL).
Available Radio Bands * You may get others depending on the radio you have installed, but I haven't confirmed this*
Automatic
EURO Band
USA Band
JAPAN Band
AUS Band
AUS2 Band
There are other settings there that I haven't messed with, maybe someone with more knowledge may be able to help
Thanks to those who found out what PRL stood for, I will try to update this info in the instructions soon.
========================
I think the reason this works is because it prevents the phone from constanly looking a round for various networks types as it I did notice that the Cell standby time is always high and using this method the cell can standby without constantly searching for a signal thereby wasting power. ALso using this method my "Awake time" is a LOT LOT lower than my "Up time" - about 1200% less (is that right 12 times lower (Up 12hrs - Awake 1hr) ?) - before this the two times were most of the time the same and some times slightly lower. - I'm sure someone will let me know if this theory is incorrect - and I'm open to and welcome that.
This is my experience you can read other peoples who have achieved a lot better than me, and I'm glad I spotted this and let you guys know. (Those who are saying that you've known about this test menu thanks for letting me know that you knew about it before, but a lot of other people didn't know about it. ALso I don't think people have used this as a tool for increasing battery in the GSM section of the forum. As I mentioned at the top of this post I noticed it in the CDMA section as a way of increasing battery performance. - credits to them for thinking it up in the first place.) -
All I am saying though, is to test it out yourself.

This is just using 2g instead of 3g, isn't it?

Like I said in the first post GSM (auto) PRL gives you 3g/hdspa but not as brilliant battery as GSM only, but is better than before.
I am now unplugged from fully charged. Will report back in the morning and throughout the day to let you know if this works.
About PRL, here's what some telecom website says:
The term PRL actually refers to file stored in your phone. This file directs the phone to find alternative networks to operate on when the primary operator cannot be reached. Updating the PRL will store in the phone which are the most up to date, current networks to operate on. In order to operate on another carrier’s network your primary service provider must have a roaming agreement with other carriers.
Almost all phone carriers, such as Oxygen, Locus, Cingular, Verizon, etc. have roaming agreements with other major service providers.

So I guess it's useful?
Suppose so.
I am on a fairly small operator in Iceland and my phone started roaming when I did this.
I lost 3G connection and went over to Edge...
Switched back to the WCDMA Preferred.... My provider has a little limited coverage but has no roaming charges on the GSM network.
Any ideas what setting I should use for my phone other then WCDMA preferred
Yea mine is on Wcdma preferred when i go into it. Im on t-mobile uk. Ive left it for now as dont really know how long this battery is lasting. Going to give it a few days to see an average

I'm on T-Mobile UK and GSM auto (PRL) gives me 3g/H and GSM only gives me gprs. Like I said, both give me loads of battery time (GSM auto PRL is a bit less than GSM only though).
Interesting, I may have done this accidentally a few days ago...
I just checked and it was already on GSM auto PRL, I'd changed this in my build.prop last time i was fiddling:
ro.telephony.default_network = 0
I thought that would give me wcdma preferred but apparently not...
I'll have done your tutorial ... will wait till end of day what happens
Definitely helped battery life.
Thumbs up!
In fact i can be wrong, but this tip only disable 3G access... only GSM and Edga.. so it save some battery for sure.. but you will navigate slower if you have a real 3G or 3G+ access.. am i wrong ?
Ciao
Fred
Surely this does the same as the button in the options to just use 2G?

Correct me if I am wrong, but isn't HSDPA faster than 3G?
source: http://en.wikipedia.org/wiki/High-Speed_Downlink_Packet_Access
in which case you would get your faster browsing using GSM auto (PRL) - giving you HSDPA. I certainly get a H showing at the top of the screen while browsing and it isn't constantly connected when I'm not browsing, which it was doing (connecting and disconnecting all the time) before I chose this setting, and thereby my battery life was extended a lot.
Edit: Just try it - if it doesn't work just put it back to your original setting, it has worked for me - There are other settings in there but I have not tested them out yet.

It may be, but not if you choose GSM auto (PRL) - also make sure you have the correct APN settings from your service provider. I did notice that the standard APN's on the phone have always been a little different from the ones on the T-Mobile UK website.
This is not a fix for the battery issues in 2.1 roms, althought it may help as 3g doesn't use the same amount of battery as 2g. But i think everyone knows that anyway. Much easier having the 2g/3g toggle on the home screen and changing it to 2g only when you are not using the web browser etc
ps: before people say other wise this menu has been known for ages and every rom I use is always on GSM.
I have finally acquired a data plan from my cell provider, and today I set up the APN settings for it. However, whenever I turn off the wifi, I only get the "G" (GPRS) icon in the status bar, with unbelievable slow download/upload speeds.
I just now tried flashing my radio to Radio_12.28e.60.140f_26.04.02.17_M2_SF (Even though I believe I had it before as well), and still I can't get it up to "H" (HSPDA).
I asked a co-worker with a Galaxy S on the same cell provider, and he has HSPDA speed at the same location as I. I also compared his APN settings to mine.
What can cause this error? Should I try flashing a different radio? is the Radio_12.39.60.19_26.06.04.06_M or Radio_12.35d.60.140f_26.06.03.24_M2 better in any way? Are they stable? Is this even the cause of my problem?
Moved to here
Go onto the dialer. Type in *#*#4636#*#* -> Phone information. Scroll down to the bottom and change 'Set preferred network type:' to 'GSM Auto (PRL)'.
Also, this is the wrong section.
This is not the place to post questions.
There is a QA section here: http://forum.xda-developers.com/forumdisplay.php?f=885
Try **#4636#*#* and select GSM auto prl
I have problems getting a 3G reception at work. My desire displays the H symbol but just doesn't connect to internet at times. If I manually switch to 2G I can connect. It's really slow but better than nothing! I can leave it on 2g all day but as the H signal works intermittently I like to try the 3g signal first before switching back to 2g.
What I would like to know is if there is there a way to change the minimum H signal the phone has to have before it goes down to E. My phone seems to prefer H even if the signal is too low to connect.
Can this be changed?
Yes.
Go to to the secret menu *#*#4636#*#* and select phone information.
Scroll down to the bottom and change
set preferred network type to GSM only.
I think this is a good idea to put through for the already excellent "Toggle2G" app. Thanks for bringing it up

Thanks, didnt know about the secret menu!
Going by the word preferred it sounds like it is what I am looking for but 'GSM only' makes me think it wont switch to 3G.
Does this mean it disables 3G completely? Couldnt I do that just by going into settings and selecting use 2g networks only?
Edit
Just searched GSM only and found this thread http://forum.xda-developers.com/showthread.php?t=688492. A good explanation of each setting, think GSM auto (PRL) is what I am looking for as GSM only is just 2G but I can usually get a 3G signal so I'll give this a try.
Hello I've been getting drained battery life, it seems the dialer caused this. Any help?

Try the following:
Go to Settings -> Sound -> disable "Quiet ring on pickup", "Pocket mode", and "Flip for speaker".
If that doesn't work, enter *#*#4636#*#* -> Phone information, then you'll see a setting called "Set preferred network type" and change it to "GSM auto(PRL)"
Don't worry, you'll still have HSPDA and 3G, it'll just search for networks on an indexed list of frequencies instead of searching the entire spectrum.
And if that doesn't work, change the skin to the default Slate theme. Not sure why that works but it did for me.
I fixes the dialer in my Rom, now it uses just about 3%
Model: Wildfire S A510e
Recovery: unofficial CWM
Rom: JxMatteo_ROM_V1. 1 with Link2sd - OC - Rooted
Could this be what you're looking for? I haven't had any problems or tried this, but I just randomly stumbled upon it in the index thingy.

The *#*#4636#*#* tip only works if you live in an area that does not have a 3G network, because it prevents the phone from searching for one though it doesn't exist. Otherwise it will not help you. To know what your network is, go to Settings > Status > Mobile network type. If it says Edge, do the *#*#4636#*#* trick, otherwise no need to mess with it.
You also need to search this forum for "dialer battery" because there is a plethora of info about it. If I understand correctly, it doesn't really have a significant impact on your battery life, only how power consumption is being reported. I had the same problem running stock HTC ROMs. Now I'm running CM7 and dialer doesn't even show up most of the time (display is always the big one), but battery life is less, probably because I've overclocked it!

There could be 2 separate issues with the battery reporting application incorrectly displaying Dialer usage and the battery being depleted extremely fast. When I first got my WFS the battery would die in 6 hours without me touching the phone (fully charged before I went to sleep, woke up - phone dead). So I know that it can't JUST be a reporting error.
For me the battery issue went away when I changed the skin from HTC to Slate. So I'm guessing it's a HTC issue.
Check this out: http://code.google.com/p/android/issues/detail?id=17383
There seems to be a lot of HTC phones reported with this issue, most notably Wildfire S, ChaCha and Evo.
