H and 3G - Nexus One Q&A, Help & Troubleshooting

After flashing CM6RC2 I can see that the data connection keeps switching between 3G and H, while it does this, my connection goes on and off, and I believe it's killing my battery as well.
I'm pretty sure it's not the ROM because the connection goes on and off while I was on stock. The ROM just made the difference of showing the data changing.
Is there a way I can make it go between only Edge and 3G, or just Edge and H? Like to try it that way for a few days and see how it goes.

No and no. Your connection does nothing wrong, you have data streaming - that's why you see H coming on. If you want to save your battery - look for the application that pulls the data constantly. HSDPA is extension of UMTS (3G), it works when you're connected 3G.

Can you give me an example of "pulling data constantly"? Like setting up Twitter to check for updates every 15 min?
Everytime my battery goes low and I check usage, the top two are Display and Cell Standby, with Display having a huge lead.

That's what you're going to have. Your battery status looks ok.
Example - setting a widget to update every minute, or setting a widget to update when it can't access whatever it needs to access. Also, if I'm not mistaken, data usage shows as a part of "Voice calls" or "Phone idle", and not as a part of "Cell standby" or "Display". I'll try to verify it later today.

Now this is curious to me, I just recently unlocked/rooted and flashed to CM6 RC1, on a Nexus One. I'm on a ATT Microcell and previous to root always had 3G at pretty constant speeds around 1.5/1.6 Mbps. Since flashing I see the H i'm guessing probably 60/70% of the time and after looking at the DalviK Debug Monitor Logs i'm pretty sure I know what widgets/apps are keeping the data connection alive. The thing is though when the H is displayed the highest speeds I see using the Speedtest app are around 0.2/0.3 Mbps which seems pretty lousy. If I go to *#*#info#*#* and click WCDMA only I seem to lose my connection altogether, although I didn't leave it there long. I'd like to go back to 3G only but not sure how to go about this, it was never an issue before root/flash, and I really like The Cyanogen Mod, my device is more stable now then when I was running stock 2.2 FRF91. Any ideas? or am I stuck with this situation until I flash something else, or go back to stock (ain't gonna happen, the stock thing).

Cyan ROMs automatically set your build prop file hsxpa to 1, but stock value is 2. This probably is limiting your speed. I know it caps my upload speed to 0.3 Mbps so I edit the value back to stock of 2.

BTW, if this thread is still up - I've checked, and the data (at least when I tether) falls under "Voice calls" category.

Is it possible to adjust build.prop to only use H and Edge?

what you are seeing is the way the microcell works, i think it only operates at a certain frequency and registers with the phone at whatever rate is displayed when the cyanogen icon is displayed for 3g, the slower data speed is because the microcell uses your own internet pipe when you use data from the cell

nope to both!

H, 3G or E

There used to be a mod that kept the phone on E always (for battery saving purposes) until data was required or being used, then it would switch to H automatically. Does that exist for the Tilt? I had it on my old 8525....
thanks

Perhaps I mis-understand what you mean but here goes... I am not aware of such a mod.
The handset can be operated in GSM (2G) or UMTS (3G). Potentially faster data connection speeds are available (at possibly higher battery drain) when you use the 3G mode (if available to you) - in this case when a 3G connection is available it may be possible to use the HSDPA data connection (automatically demanded by your hanset only when data is required) but that depends upon: whether you have that service available from your providers masts, whether they have enabled for you it and also whether your handset has the HSDPA setting enabled.
On the other hand only GPRS or EDGE (see wiki here) may be available when a 2G/GSM connection is available. EDGE is basically an enhanced version of GPRS but does not match HSDPA speeds.
So you are mixing the EDGE data indication "E" with the HSDPA indication of "H". The only way your handset can go from EDGE to HSDPA (or vice versa) is if your signal received changes to provide HSDPA from EDGE (perhaps as you change location).
Of course you can disable both 3G and seperatly HSDPA - then you are left with either G or E (use the comm manager and/or the various tweakers).
Beware - some ROMS are incorrectly showing the H instead of 3G when no data connection is active and this is a known problem.
Probably too much detail but may help .

He needs a program to switch between those modes automatically instead of manually though the comm manager, when he enables/disables a data connection..

yeah, that is right.
You know what I do. I use Kaiser Tweak or AdvancedConfig to tell it to Disconnect my 3G connection after 3 minutes. Then When a program needs Data it connects to The 3G network, than when It doesn't need it it disconnects after 3 minutes. Phone still works otherwise. And My battery lives for days.

Let's see if I get this..
You want to run the handset in 2G (GSM) mode for normal voice comms but when you want data you want to switch to 3G (UMTS) so that HSDPA can be used?
I personally haven't seen anything that can do that automatically and understand the problem is that to change from one band to another actually requires a cycle off of the actual phone. There are plenty of programs out there that cycle the phone mode - perhaps you should put this requirement to Dani who has developed a Comm Manager Pro program - his software does this cycling of modes but based upon time and place (for instance) rather than the trigger that you want which is when a data connection is required. Try looking at this http://www.commmgrpro.com/ and asking Dani who is always on this site with the Hermes forum here: http://forum.xda-developers.com/showthread.php?t=299070
Good luck .
Gotta be careful forcing the phone to Edge/HSDPA. Particularly if you force it to HSDPA.
I took a 2 hour road trip today and it took me coming back to figure out why my phone wasn't even getting a signal; it was forced to 3G. I set it to Auto in BandSwitch and it had a signal immediately.
Whoops!
speaking of road trips and HSDPA...
i took a trip today with my wife to Washington and had perfect signal the entire time.. until my battery died of course.
but HSDPA all the way..
i live in Jersey and have travelled to the NYC, the UK and Puerto Rico and have yet to get bad reception...with my old blackberry... im damn near posivtive i woulda had lag

i manually control my data connection through comm manager. i always have 3g off too on comm manager. However, my battery sucks ass and it doesn't last longer than 18hrs with normal use. However, my backlight is at full blast because i can't see the screen outdoors if i don't have it set to 100%. Wish i could see the screen outside during the day and i wish the battery life lasted longer.

I usually cup my hand to act as a shade around the screen. I can see the screen well enough at the 3rd lowest setting.

Have you noticed any kind of lag in your device when using the AdvancedConfig auto disconnect feature? I "feel" that when I have this feature turned on the device lags a bit. So instead I have the long press end key mapped to terminate data connection and I end up having to hit that so many times during the day.
Hello
This is sort of on the same lines. I use the com manager built into the custom rom im using ( L26_Kaiser_Diamond_V9 ) and throttling back from a 3G/HSDPA connection to the Edge signal. Ive noticed a huge difference battery life. Before i would only get about 4-5 hours standby because I had an application running that kept the HSDPA active previously. If you use a messenger service like IM+ I strongly suggest upgrading to a rom like L26 that has the ability built right into its com manager. It more than doubled my battery life with 0 cost to messaging performance. If i have to hop onto the net or tether, its a simple button switch to re-enable 3g

3g how long before connection issues?

how long can you browse or stream on 3g before the connection dies when you have full signal?
I'm getting three or four pages, then I have to enable airplane mode to reset the connection. actual speed is great, and signal strength good, but connection time is never over five minutes. does froyo contribute to this?
i'm using the default (no root, nothing special) froyo with the included radio on a stock non-root n1.
So far, I don't see an upper limit on how long my connection will last. It has never cut out on me. So I say I can load an infinite amount of pages before it cuts out...
What Radio/Software are you using?
I'm on stock rom, stock browser on Fido. Latest Radio.

i should have input my current config... updating original post
it doesn't matter if i use the default browser, or dolphin, or any other application. after 4-5 views/pages/whatever it will end up with a non working connection. it appears that the is UP travel, for 30 seconds to a minute or more, but no DOWN travel at all. during this time pages will disply "No Connection at this time, try again later" or a similar message.
I'm using my n1 on tmobile, with 3-4 bars of 3G coverage, while stationary. doesn't seem to matter if i'm on a tower i usually use @ my home, or at work, or where. it's a pretty consistant failure of traffic.
I can go hours. In fact I've never had this issue I've read about.
It sounds like you've eliminated all other options. i.e. does the same thing no matter where you are or what the signal strength is.
Which normally should mean it is on your end. Do you have any apps installed that could interfere? Maybe some data transfer meter, or some apps that are auto syncing?
Ive had this same problem no matter what rom or radio im using. My phone shows a 3g connection with full signal but pages wont load.

none nope
hmmm
My connection could get stuck some times, but that was before I updated to Froyo. What would happen was that it would seem to be constantly uploading and I couldn't use the connection for anything so I had to go airplane-mode and back.
Don't really know what the issue you have is though, especially since mine went away with Froyo. I've been browsing for _long_ periods of time after I got Froyo without any issues so...

Always on hspda?

Is there a way to force the phone to always be on hspda?
Normally it would switch back to umts after like 2 seconds after being done transferring data.
I read a lot of comics, and switching between comics takes a few seconds every time because it needs to switch from umts to hspda. When it for some reason already is using hspda it loads the next comic in a second. So it can save quite some time if you read comics a lot.
Also will it significantly drain more battery? I will of course set it back to standard when I don't use my phone.
Thanks in advance.
No you can't. It's the network that switches you over, not the phone.

Okay. Thanks for the quick and helpful answer.
is there a way to force a faster switch from umts to hsdpa?
when i hit a link in my browser i notice that it takes 3-10 seconds before umts switches to hsdpa.
The only thing you could do is have something constantly using the data connection so it never drops back to basic 3G.
You can set your phone to only use an hsdpa/umts connection by dialing *#*#4636#*#* and chosing WCDMA Only in the Phone Info section.
Edit: whoops didn't really read the OP. this doesnt help

You're right, I guess running a ping command from a terminal client will do just that. Atm I'm on gprs only since I'm home, but it seems to keep the data connection busy while it runs in the background.
To the battery thing: yes, it'll drain the battery much faster.

3g vs 2G battery life - way too varied

I have a ATT type Nexus One (not Tmobile), unrooted, with latest froyo.
The life of the battery in 3G mode vs. 2 G mode is astonishing...pretty ridiculous.
I'm searching but can someone tell me if there's been any fixes or advancements in regard to this problem?
When at home I use wifi as much as possible. I leave it on 2G but really, I can't take the slow speeds of 2G, but 3G setting is suuuuuuch a drain on the battery that it seems unreal.
i've had nokia's and more in 3G, my wifes iphone is 3G... and all of them had nearly more than double the battery life.
I hate the voice quality of 2G, I'd love to be able to just leave at 3G, but it's merely hours before it's nearly drained set on 3G. it's got to be a problem (and one that hopefully can be fixed).
Why would 3G setting be sucking THAT much power (decent-strong signals too here)?
Love my nexus1 and I'll live I guess but this problem...it's a bit much.
Any news on this issue, or other things I can consider or change/try to help this? (3G)
thanks
Set your WiFi sleep policy to NEVER. Even thought you're using WiFi at home, whe nthe screen goes off the WiFi shut off and 3G kick in.
Menu>Settings>WiFi settings>Menu>Advance>WiFi sleep policy>Never.

Oh very sorry, I should have said I did set this to never and saved changes.
In fact, I think I've set it 1000x now btw, over some time it STILL always disconnects from wifi (might be router disconnecting though, perhaps I should set an IP manually to solve this??).
GPS and BT are always turned off until needed as well (used very rarely anyways btw).
But when I'm away from home for example, I turn wifi off and test the difference2G vs. 3G and the difference is waaaaay too much, 3G just CHEWS at the battery no matter strong signal or medium.
I find it hard to believe 3G really has to eat up that much battery when set compared to 2G on a Nexus. A little bit to nominal ...sure, but not like this (say like 4-6 hours if i left it 3G for a day with little usage).
What's really happening here? Nothing from google/HTC on this matter?
Heh, i get just the opposite... out in the farmland of west toledo, im getting 2G but typically GPRS and that rapes my battery where as 3G i could go on standby for days if i didnt touch it...
What radio are you running? if your phone is constantly looking for a signal then that may be your problem...
I have the same issue on 3g. Home on WiFi is ok but when I go out during the day on 3g it just kills my battery.
The reason is because android OS keeps the data session open at all times where other OS's close it down when not in use. It's just the nature of how they designed android.
As a test, one day turn off your data connection but stay on 3g and see how good your battery life is. This is how some other OS's work normally.
It's a trade off we have to make for being always connected on android.
For example voice actions need to reach out to Google's servers to work. So in the interest of speed of having to open the data session each time, the OS just keeps data open on hand at all times. But that kills battery quicker.
That's what I've found anyway.

That's because the phone is always on the lookout for a 3G signal, if you know you aren't going to get one, just set it to 2G only and your battery life will massively improve.

[Q] [Modem] Non-HSUPA Modems?

[Q] Assuming whoever reads this post is familiar with the 4G, 3G, Edge monikers could someone let me know if there exists a modem for the captivate that only uses Edge?
[Reason for Question:]
Yesterday, messing around with settings I noticed that my phone has the ability to change from 4G/3G -> E. Doing this I noticed an immediate improvement with my battery life. I could surf the net, read emails, get notifications, and do everything I could do before. Just now my battery could last for 2+ days.
I am fully aware that a 4G connection can be faster than 3G and a 3G connection can be faster than E.
Although, I thought about the logical progression of events that may occur in my life, and if I ever found myself in a situation where I would need to download a large file it would likely be in response to something premeditated.
Therefore, I would likely be at some location where WIFI would be accessible or, if not, I could always remember to download it before I actually need it.
However, extrapolating that thought process out further, I thought okay well if there is WIFI around then there is a need for it. Therefore devices that can download and process at much faster speeds could be available. If those devices aren’t available I still have the ability to hop onto the WIFI network and download using my integrated wireless NIC.
Using this I have deduced that I do not, or will not ever, need High Speed connections on my phone. I do however like the android operating system and love my phone so I am in a bind. On one side there is the smart phone market and generation saying "faster is better" and on the other side there is me saying, "I want a phone that I can play some sweet games, utilize useful apps, check email, and have a true internet browser experience but at the end of the day I still want to be able to make a phone call damn it".
Don't get me wrong having ridiculously fast internet on my phone is cool but so was smoking when I was 16.
I'm not aware of an edge only modem.
Also there is no voice and data at the same time on edge. So if something is using data at the time you get a call it will go to voicemail. Just putting that out there in case you did not know.
settings>wireless and network>mobile networks> set network mode to gsm only.....
That way if you ever DO need 3g you can turn it back on too!
Thanks BenKranged and studacris .
I decided to go with Serendipity Rom -> http://serendipityrom.weebly.com/
Disabled HSDPA -> http://touristinparadise.blogspot.com/2010/11/samsung-galaxy-s-turn-off-hsdpa-for.html
And if I want to I can only enable Edge as studacris explained.
I now get 2+ days out of a single charge and moderate to light use!
I am satisfied now!
p.s. Plus I flashed the ability to record calls so that is pretty cool too!
