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.
Hey I just came from Galaxy S and there is a way to disable Hsdpa in there which improves battery life amazingly....
I was wondering if there is a way to do that in Desire? (for my city 3g speeds are faster than hspa for some reason)...
Also is there a way to select which band the phone is connecting by 850 vs 1900 ... or to see what it is using ?
any help would be appreciated
It's in the settings someone in network
There is also a widget to totally disable mobile internet which I use to save battery
Sent from my HTC Desire
Go to Settings > Wireless & Network Settings > Mobile Networks...
That's pretty much what you can do with the Desire as far as mobile networks are concerned. GSM phones normally switch to different frequency bands depending on where they are located and in the Desire I don't think you can select which one to go for (besides it's an unnecessary feature in my opinion)...it just does it on its own. Maybe there is an app around that let's you do this?...
As for viewing which band you are on....you can't do it on a standard ROM but there might be custom ROMs or an app that let's you do this.
Update: Some apps that might interest you => 4G, CDMA, GSM & Wifi Map Viewer from Sensorly.com
=> Open Signal Maps Beta from Staircase 3, Inc.
=> Antennas from mpoly
=> Quick Settings (maybe..)
mmm none of those do anything like it...
all those either just shut off data or turn it on... im not sure if anyone has used the galaxy s
http://forum.xda-developers.com/showthread.php?t=837716
this is what im talking about... saves the phone a LOT of battery by just forcing it to use 3g instead of hspa ...
i think developers can prolly make more sense of it.. i mean if they have a way.. there has to be one in other devices ...no?

Ah, so you have a Galaxy S.....unfortunately, this is a HTC Desire forum, so it would be better if you posted this in the Galaxy S forums. You may not find the answers you are looking for here as this forum mainly handles a different device to the Galaxy S.
What I said before is only applicable to the HTC DESIRE. I thought you switched to a Desire when you mentioned you came from a Galaxy S, but I was mistaken. The apps I mentioned as mainly for monitoring the 4G, 3.5G & 3G (i think 2G too) coverage. If you are looking to switch between them (i.e. turn HSDPA off and turn 2G on) I am sure there is a way to do so...on the Desire this can be done through the Mobile Networks settings...
And no, I'm not familiar with the Galaxy S....
no i had the galaxy s... (i posted that for reference as to how its done on that)...
and ya those apps just toggle just 2g vs 3g...
im looking for a umts vs hspa toggle... (3g vs 3.5g).... because umts takes way less battery than hspa does...
tried to mess around in the band setting screen but couldnt find anything
SOLUTION
what you need is to edit /system/build.prop file
here are my settings:
ro.ril.hsxpa=0
ro.ril.gprsclass=12
ro.ril.hsdpa.category=1
ro.ril.hsupa.category=1
after doing the and couple?... of restarts H icon changed to 3G and it really does save battery significantly and speed is pretty much enough for browsing or email
would have thought if battery life was vital then you'd disable data completely tbh
This is somewhat network dependent. Here in Sweden I know of one network that will have you at HSXPA (H) as soon as it is possible. My network on the other hand will set to 3G when WCDMA is detected and set to H only during data traffic.
And then G if only GSM is detected.
I disable data via widget if I want to save power even further. Not that it has that much impact. There is a setting under wireless and network > mobile network at the bottom : ativate mobile data (this is translated). This setting will force the data connection to be active even if unused. You have to experiment here what setting is best for your network. On my network, if I remove the tick here (data connection will let go if not used and reconnect when needed) my battery will drain quicker. Providers with other policies might give different result.

Thanks! Very useful! For me it was only necessary to change the "ro.ril.hsxpa=0" line, then do a couple of restarts (to make it clear, a single restart wasn't enough, HSDPA was disabled only after the second restart for me).
Since I was not happy with my current battery life I decided to invest time in finding ril build.prop tweaks for our hd2. Wich will be readed by lib_htcril.so and will acutally work. Android htc ril interface supports over 60 commands.
All tough it looks our phone has a working data connection it works far from optimal. There is no rill officialy developed for our radio and singal is very sensitive in my experience.
RMNET is currently providing us stable data by loading desire rmnet radio code into the radio when start up. Altough we should know wich radio from the desire is included so we can use the right wrapper
Anyway I will here clearify some commands.
ro.ril.fast.dormancy.rule= 0 - 1 disable enable.
Save a lot of battery by letting the phone request for fast dormancy. Phone will stay in UMTS until data is requested and will then switch to hdspa. This is not supported by all providers.
ro.ril.fd.scron.timeout= 0- to infinity in theory
The timeout in seconds after a data request before switching back.When screen is on
ro.ril.fd.scroff.timeout=0 to infinity in theory
The timeout in seconds after a data request before switching back.When screen is off.

ro.ril.enable.a52=0-1
disable enable encryption a52
ro.ril.enable.a53=0-1
disable enable encryption a53
ro.ril.enable.dcm.feature= 0- 1
Database Correlation Method to get phone location I was getting faster an data connection when on however phone was finding this value by it self was my experience.
ro.ril.radio.svn= 0-99
to identify phones more easily currently displayed as 01 on our hd2.
ro.ril.qos.traffic.priority= 0-3
(lowest priority =0 highest =3) request QOS priority in your network might not be supported by your provider.
ro.ril.enable.dtm=1
Dual transfer mode for networks that support calling and data connection at the same time.
ro.telephony.default_network=3 (0-8)
Not really new this will make the phone prefere a strong gsm singal over a really weak hdspa can save a bit of battery. This can also be set by typing *#*#4636#*#* in dialer
This are the ones I exactly know what they mean however after some testing I am using the following commands in build.prop by researching htc build.props
Altough I don't know the meaning of all it definately helps because I dont get a weird logcat out put when turning data on or off and it goes almost instant on and off with b4 wrapper in CLK.

Just some more clearyfing why we have high standby usage.
Because phone is searching a lot for singal in my case it can swtich from 1 bar to 5 bars in the same room.
The power usage in 3G can be reduced by using fast dormancy because the phone doesnt switch from 3g to hdspa when there is no data request but phone will still search for optimal singal but it wont constantly switch between 3g and hdspa and waste battery. (lost 4 % in 8 hour with constantly bumping singal)
What is the goal of this thread:
Giving everybody the chance for an optimal data experience and maybe useful for devs who wanna update radio code or update ril wrappers.
Thanks for this Jan. So can we simply copy/paste this into our build props and reap the fruits of your labour?
Yeah it should work especially that fast dormancy really hepls if your network support it. I tested this in combination with clk b4 wrapper in theory when we initialize ril on boot using tytung r10 instead of lib_htcrilwrapper.so it should work for sure.
So is this for close or maglder it both?
Either way thank you this whole battery drain issue has got me very angry lol
Sent from my HTC HD2 using XDA App
Yeah well you just need to test I they will work for both. It depends the most on your provider. I Think because lack of missing code system has trouble by setting some parameters by it self. That is why It might be needed to apply the ril tweaks in build.prop.
Agree with the signal strength... my connection shows H, perfect reception when its laying on my desk, but as soon as i pick it up data drops to 1 or 0 bars. VERY sensitive.
Switching to GSM auto (PRL) seemed to do the trick for switching from H to E faster so i wont lose my reception and fixes the battery drain but this is still far from optimal use of our data connection as the data drops still occur as frequent as before.

Hi,
This is very cool set!
i will use it in my ROM,
Your name will be in my build prop.
but first i will check that all ok, dont want my users to lose data / wifi / signal.
better test on my self!
Very cool keep it UP!
Thanks!
Can you please make this a flash able zip through CWM.
Ive had a a few problems in the past editing build props
CWM is not possible because each build is using a different build.prop
@dorimanx only issue is that some networks dont support fast dormancy. And then it will use extra battery instead of saving. Then you need to set fast dormancy rule = 0
For the rest I don't see any disadvantage of using this tweaks.

What about T mobile is that ok?
Sorry I have no tmous device try google to find out if network support fast dormancy or try out by yourself you can see it when you have high battery drain in 3g mode.
I already have a high battery drain cause of this http://support.t-mobile.com/thread/3544?tstart=0
Then I would try the build prop entries for sure.

If you have to ask this you should really also be asking yourself if you want to be getting into something you don't understand. However should you choose to take the red pill then...
1. DO A FULL BACKUP IN CLOCKWORK
2. Install Root Explorer, File Expert or ES File Explorer from market (if one of the latter two enable root explorer option in settings)
3. In your chosen file explorer navigate to /system and locate build.prop
4. MAKE A BACKUP COPY OF THE BUILD.PROP and save it on your SD card somewhere.
5. Open the build.prop file and search for the lines of code in Jan's OP. If they are there then simply edit the values. If not then copy and paste the new code.
6. Save the build.prop file
7. Reboot and hold on...

Hello I've been getting drained battery life, it seems the dialer caused this. Any help?
Sent from my HTC_A510c using xda premium
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%

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.

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.

There seems to be a lot of HTC phones reported with this issue, most notably Wildfire S, ChaCha and Evo.
Lost connection with O2 while 3 miles offshore - in full view of Bournemouth, Poole & Swanage. Came ashore, still no connection. Drove 4 miles home, still no connection. Only re-connected after power off and re-start. Had similar connection drop once before.
Is this lack of re-connection usual, or is there a fault?

Sorry for the belated reply. If you haven't yet resolved this issue, there are some remedies you can try. Sometimes, while traveling abroad, or otherwise outside of the normal coverage of your mobile provider, it may be necessary to change your band parameters within your cell radio menu. (To do this, open your dialer and enter *#"#4636#*#* and select PHONE INFORMATION from the list of options. This menu provides pertinent and technical info regarding your cellular radio (baseband), and gives you the option to change your preferred network type and band configs) But to start, I'm not very familiar with the O2 network; from my rudimentary research, it appears that its 2G, 3G and 4G coverage is vast and quite impressive overall as a global provider, claiming a 99% global 4G coverage area. So, I am in full agreement with your position -- that the disconnect you are experiencing is abnormal. Try these possible remedies:
• First and foremost, let's make sure your network configuration is optimal for O2's voice and data parameters. There are a couple of ways to do this, with the simplest being from device settings. Go to Settings>System>Advanced and select the option for Reset WiFi, mobile & Bluetooth. (Ensure that you are within a strong 4G coverage area when performing this step). Next, go to Settings>Network & Internet>Mobile Network>Advanced>Preferred Network Type. You will see a few options here, the first of which should be AUTOMATIC. Ensure that this option is set. Next you will see a menu for Access Point Names; select this option and ensure that (1) your APN is set to an O2 configuration and, if so, (2) that the parameters are correct and optimal for 02's recommended settings for your particular type of mobile plan and your region. O2's recommended APN settings, as well as a comprehensive how-to guide, can be found on 02's official website at this link:
https://community.o2.co.uk/t5/Android/Connecting-Android-Phone-to-Data-Services/td-p/544202 It appears that 02 can send the recommended APN settings directly to your device via texting the word ACTIVE to 2020. Once received, a normal reboot will be required.
Hopefully, these remedies will resolve your carrier disconnect issue. It is also very important that you are updated to the latest available Android OS version/build, because updates and optimizations to your radio firmware (baseband) are often encompassed within OTA update packages. If, after performing these steps, you are still experiencing the disconnect issue, please let me know. There are some more in-depth steps we can take to resolve the issue (e.g. the Cellular Radio Menu I mentioned in the beginning of this post.) There are also some fastboot commands which can be executed to more efficiently optimize your network settings to the parameters of your provider. Good luck and let me know if this works.
