Hello,
I have a G1 currently running Super D and 2.22.19.26I radio. This problem isn't specific to this rom or radio, since I've flashed various donut/eclair roms and various radios during my year of ownership and have always had the following problem:
When there is a weak 3G signal (one bar of 3G shown), it seems like there is an annoying delay or freeze in data connectivity, where rather than switching to the edge/2g signal, the phone just sits there on one bar of 3G doing nothing. Then, if it switches to 2g there is data loss, apps disconnect, web pages fail to load, etc.
I realize I can manually switch to 2G only mode, but this seems to happen all the time (there are not many times that I have a speedy 3g connection). I would personally think the radio firmware could be "smarter" and know not to look for a signal so much. I would rather not be on 2g all the time if 3g is available. Has anyone else had radio problems? Maybe someone can help me understand how the radio works better and maybe I should just stick with slow 2g most of the time.
Thanks

For comparison sake I have an old stock razr v3xx and I get FULL service in my room with it.
On my at&t tilt, I get 1-2 bars.
Im running Slueth 3.0 (WM6.1) and I've tried different combinations of HardSPL's and Radios but each one gives me problems that I can not fix. (i.e. - some SPL's have certain bugs where i get a text and it vibrates until i change the ringer to silent, and any other radio than the stock slueth (1.64.08.21 - which I need a link to if anyone can find?) makes my camera not work and I get a black screen.
One thing Ive noticed is on my razr, the band always says 3G. On my tilt, it says "H" - which Ive never seen before. What is "H" - and could this be the reason for poor service?
Again, if anyone knows where I could find Radio 1.64.08.21, and the disable xt9 cab I would greatly appreciate it. (I have searched for both but to no avail for a working link)
H is for hsdpa its just a nother type of service, gprs hsdpa 3g are the main in the US.
No "h" it isn't the problem.
try the ultimate radio thread for the radio you are looking for.
yeah i did, 1.64.08.21 isnt in there
can I force my tilt to choose 3G? My razr picks up 3G with full service yet the tilt uses H with hardly any
I have really awful service too. It loses connection from 3G every 10-30 seconds sometimes, but other times it can sit connected to the 3G.
Sometimes it won't even connect to 3G, then when I soft reset, it connects at 2 bars. Right now it's sitting connected at 3 bars.
What's up with this, and is there any way to improve it? The nearest base station is only 2-3 miles away.
I'd recommend trying out different radios.
Also H stands for HSDPA which is considered to be 3.5g but it actually is 9x faster then 3g.
jay487, search harder.. i found the disable xt9 cab in one search for "xt9". as for the radio your looking for, check out the wiki.
if you change the band to GSM in the band tab in the phone settings the signal will get better if you turn off WCDMA which is 3G or HSDPA, if you don't use 3g for internet then turn it off it will help
yeah I changed the band to GSM out of curiosity and it definitely seems to help so far. I dont use 3G for internet just for picture messaging, this shouldnt be affected correct? I also just did a complete reload of Sleuth to resolve the radio issue.
One problem I still notice on occasion is my sounds will just stop working. If i get a text the sound doesnt play, and if i set it to vibrate when i get a text too sometimes it constantly vibrates until i change the sound to silent and then back. I can fix it with a soft reset but having to do this everyday is anoying.
Do you need a specific program or app to disable 3g or hsdpa? i have the exact same problems, ATT +tilt= bad recep and lots of dropped calls
thanks

Hi Guys
well did a search and couldn't find a topic about this, however if there is Sorry.
Anyways got my 02-Uk simplicity yesterday and set 3g and MMS up all fine, and was working fine, however today I came to work which is a bit out in the sticks so hard to get a 3g signal, and because of this i noticed I lost all signal.
after playing around I noticed that switiching it to "2g networks" i managed to get a full edge connection. My question is how come if it loses the 3g connection does it not revert back to a 2g network? I know there is a 2g connection beacuse if i do it manually it works. is there a way to do it automaticly?
also i do have data roaming connection active, and can post my APN details if anyone thinks that will help reslove the issue.
Thanks
matt
Brought mine in to t-mobile to ask the same question. they said just stick to 2g only when you're not in a known 3g area. They also recommended just turning data roaming off
I have the same problem with my Goophone Y6.
2 solutions I know:
1) Flightmode on/off
2) Reboot
This is very anoying, because the bug apperas again. One question: Do you lose signal when you turn your display off or after approximately 5 minutes?
Recently my signal is constantly switching from G, 3G and H (sometimes full bars with no signal icon). I'm at work so not in a new poor reception area. It'll switch even if I move the phone a couple of inches in one direction. Generally getting poor reception tho.
What I'm wondering if whether to speak directly with TMob or whether it's a) atmospheric issues or b) something to do with my Darky ROM flashed modem (BUJP5)
I have a sneaky suspicion TMob won't help if they discover the phones seriously modded.
It's causing me a lot of grief
Thanks in advance for any advice
Well, I guess I'll sort it out myself.
It appears that it might have been a couple of things; Juice Defender seemed to screw up reconnecting to 3G leaving me with full bars but no signal plus the Preferred Network Type was set to Unknown. I've now changed this to GSM/CDMA auto (PRL) and my signal seems to have stabilised (still a lousy strength tho)
Clue to problem board is littered with problems from one rom and thats it
.
Its the rom remove that before trying anything clean wipe and stock install .

For quite some time now, my phone has been having some terrible 3G connectivity issues.
It just drops from HDSPA to UMTS and gives me no data for chunks of time. And every now and then, the entire 3G turns off(as if the APN has been switched).
This has been occurring with MIUI 2.2, MIUI 2.3, CM6 and CM7.
Im using 5.12.00.08 radio (latest i think). Im unsure what HBOOT I'm running, but the full baseband version is "32.50.99.32U_5.12.00.08". So i think I'm running HBOOT 32 but im not sure. With the CM and MIUI roms the problem was occurring on stock kernels and monk's.
Any ideas on what could be causing the issues? If you would like me to send logcats i can(i haven't seen anything in there to indicate any issues)...
Also i found a post:
http://forum.xda-developers.com/showthread.php?t=931728
Not sure if thats related.
Seemingly the problem started occouring after i was using alot with WiFi Tethering with Wireless Tether by Lemons and co.
I'm using Virgin Mobile AU as carrier.
Also, the problems occurs before installing ANY apps as well(and afterwards obviously).
32.50.99.32U_5.12.00.08
mine is only 32.50.00.32U... IMO just try flashing a new radio, start with 5.08 instead of 5.12 and see if that works then if you are content then leave it... else flash 5.12 after and try to root out the problem...
cheers!
The default setting in nexus one is WCDMA preferred... i.e. it connects to 3G if available.
If the signal strength of the 3G network is lower than than 2G network,
it switches to 2G rather than connecting via 3G.
However, Its a known limitation that Nexus one 3G reception is comparatively less due to physical properties of the antenna.
Hi guys,
I have a Nexus One purchased from Google last year. I only started using 3G this month with Vodafone Australia. My battery drains ridiculously fast on 3G compared to 2G. On HSDPA("3.5G") network with everything off (including data) it uses 5-10% per hour standby. On 2G it drains less than 1% per hour. Using a battery monitor app I can see that 2G draws less than 10mA while 3G draws 25-100mA.
Since on 2G battery life is very good this should not be a problem with any software running in the background. I also tried the following with no help:
- Dial *#*#4636#*#*, set to WCDMA only instead of WCDMA preferred, and select radio bands to AUS BANDS
- Upgrade radio to the latest Korean version
- Force the phone to use UMTS instead of HSDPA network by editing build.prop
I tried both the stock 2.3.4 ROM and the latest CM nightly, but the problem persists. I really want to take the full advantage of 3G and leave it on all the time so this is very frustrating to me. I can use Toggle2G to automatically switch to 3G when screen is on, but that's not what I really want. I know although 3G uses more battery it should not be that dramatic. After all the specified standby time on 3G/2G are 250/290h by Google. With 3G my phone won't last even a day purely on standby.
I also wonder if it can be a problem with the network. My signal strength on 3G is around 2 bars - not particularly bad. It almost never loses signal. If anyone can post a ROM/radio from Vodafone Australia for me to try out that would be greatly appreciated too.
Thanks all!
2 Bars of Signal strength might be one of the reason that battery is drained faster. As the signal is not that strong enough, it keeps searching for stronger signal and results in faster battery consumption.
Personally the radio version '5.12' wasn't satisfactory. I prefer 5.08 version. (Signal strength, speed, battery...)
I recently upgraded from CM 7.0.3 to 7.1.0 RC1 and noticed battery life is much better.
So I am going to suggest a few things you might want to try:
- Downgrade the radio to 5.08
- Full wipe and flash CM 7.1.0 RC1 (or a different custom ROM)
- Try a different kernel (I personally like Cyanogen kernel though)
- Uninstall Task Killer if you have one installed.

Hi zephyr, I previously had CM 7.1.0 RC1 with radio 5.08 and the Cyanogen kernel but the problem remained. I also tried to put my phone near the window, where it has 4 bars signal, but the battery drained just as fast. Thanks for your suggestions though.
I know T-Mobile in the states screwed up something on their network a few weeks back. In doing so, it caused massive power usage on devices when using 3G/4G. I wonder if Vodaphone Australia did something to their network as well...

install current widget, and take logs of your current draw in mA during idle to see what's going on. do an overnight test, then during the day. post your logs.
So I just stumbled across this thread. I've been having the same issue on my Desire, it started suddenly a couple of weeks ago. In 3G mode my phone drains about 120mA. In 2g it drops down to 4-8. I've eliminated all the usual suspects by doing a factory reset (using the CM7.1.0RC but have also tried the latest nightly build), so no apps running in the background, and tried different versions of the radio. I am also with Vodafone in Australia. One thing that I have found is that if I go into Phone Info I can force the phone to make an EDGE connection by choosing the "AUS2" frequency band, and with an EDGE connection I get the good battery usage. But if I choose "AUS" or "AUTO", the phone makes an HSDPA connection and this drains the hell out of my battery.
Just wondering if the OP has had any joy with this?

Try Juicedefender Ultimate, it shuts down data when not in use. I see 1-2%/hr max when used with a good kernel.

Alas it's not the data, this happens even with the data turned off. It's something to do with the baseband connection.
It's not data here either.
This just started happening on my 100% stock unlocked N1 about 2 weeks ago. (ATT)
Most of the time at work I'm on WiFi, yes the signal (cell) is very bad in my office. Has been for a long time, something else is strange.
No extra tasks running, nothing new installed.
Gets piping hot when on the charger - sucks juice like crazy when off.
Checked data log - nothing unusual transmitting...
What sort of area do you operate your phone in? My phone used to drain like mad inside my house (perth- vodafone) and in areas with spotty coverage. In my house my reception would be on the very edge of 3g with no bars and EDGE, constantly switching between the two. Do you have your wifi policy set to on while sleeping? Provided you aren't out and about all day, that would help, though i assume if you've had the phone that long, youd have changed the wifi sleep policy by now.
My wifi is always on - never has changed.
It gets hot at home where there is good reception and at work where there is crap.
I've had the phone for over 1.5 years and this just cropped up.
I rooted my wifes N1 and she doesn't have any issues...

I'm also in Perth, on Vodafone. I get a pretty decent signal strength at home, and it seems to be happening to me wherever I go, unless I'm "lucky" enough to get an EDGE connection. This started overnight, almost exactly two weeks ago. I've been speaking with Vodafone about this at length but not really getting anywhere. Yesterday they swapped my SIM but it didn't make any difference.
Yep, wifi is set to never sleep.
I bought a prepaid SIM card from another provider a few days ago. I only get a UMTS connection with them, but still the current drain when idle is what is considered "normal", 4-6mA.
One thought I've had is that maybe I never had an HSDPA connection before but recent network upgrades have meant that I'm suddenly getting one. Still, 125mA is way too big a drain and seems to indicate something wrong with the phone.
The last test I can think to do is to swap SIM cards with a friend who is on a third network, who gets an HSDPA connection. He has a Nexus One and gets very low current drain. At least that way I can be sure of whether it is or isn't the network. We're doing that tomorrow so stay tuned
