Anyone can answer about data connection?

When I read the HTC Desire user manual, it said that I need to turn on the "Data Connection" setting to have internet connection.
Well, this is understandable ... but, does it has automatic connection on demand?
On Windows Mobile, I dont have to specifically turn on data connection. Whenever an app is trying to reach the internet, it will turn on the data connection automatically.
And of course, it will turn-off the data connection automatically as well, when there is no internet network activity.
Does this also the same in Android?

It should turn on automaticly when you try to use online services...
But you can turn it on in Wireless & Network

You have to option to turn mobile data off, that is why it specifies that you need a data connection.
If you do not turn it off, apps that require internet access will use it with no further interaction.

By default MENU -> Settings -> Wireless & networks -> Mobile network was off on my device, meaning it would not connect to internet via 3G (I could still make/receive calls). However, I chose to use WiFi for set-up when I first started the phone, so maybe that's why.
Anyway, I guess that is the setting they are talking about.

Thanks for your information, but that raise a question:
When I switch off the data connection and also switch off the background data option.
Will the HTC Weather widget (and other similar widget) still work with auto-updating periodically?

NO... they need either 3G or WiFi connection to update...

So, that means ... those apps cannot wake up (turn-on) the data connection automatically if needed (on-demand) ...

I do remember the old days of the HTC Hero which had the option of background data usage. I think that was more to do with the version of Android than anything else. I recently had the Nexus One and on the new 2.1 version of Android, you can either switch data on or off, no automated connections on data usage.

When the phone is sleeping (screen off) nearly everything is powered down anyway, even if the data connection is 'on'. Apps will wake the device (an power up radios as required) to do their updates when they need to.

The whole idea of being able to turn your mobile data connection off is to disable mobile data completely. This is a very good option if you are roaming in a foreign country or don't have a fixed data plan.
If you leave the mobile data connection to enabled, applications will "turn-on" the data connection if needed (on-demand). In other words, if the mobile data connection is enabled, the mobile data connection will be in standby, waiting for applications to request use of the connection.
Hope this clarifies it for you, as you appeared to misunderstand my last post.

Ok then
I think it has different meaning compared to the Windows Mobile.
In the COMM MANAGER, there is "Data Connection" toggle which normally is OFF. And this does not mean that the device cannot use 3G data connection.
While on Android, its data connection toggle setting means to enable or disable 3G data connection completely.
I think that is the difference, if we look from Windows Mobile point of view.
Thanks.

Help...Urgent!

Hi
My phone (HTC Desire HD) is acting very weirdly.
Problems
1. I cannot cannot connect to the internet via my mobile network. It says "use phone for data connection when Wi-Fi is unavailable". I have tried to fix this by doing various things such as doing a reset but nothing works.
2. I have a broadband connection (Wi-Fi) which requires an IP address to be entered. I cannot enter this IP address anywhere and I cannot insert my username and password anywhere in order to surf the internet.
3. I keep on receiving texts from a certain contact with information about my bill for my network service provider
4. My location is stuck on a location, I haven't been in almost a month.
5. My battery life is very poor even with mild usage.
Are these problems from the new update (Android 2.2.1)?.
Please how can I fix these issues?
Anyone have an idea when android 2.3 will be released for the DHD?
Thanks

bump - comon guys someone help me out!!

Hi,
1. What is your settings configuration right now ? (rooted phone, android version ?, did you flashed the ROM....)
2. For the wifi, it's really simple. Go to Settings -> Wireless & Networks -> Wi-Fi Settings and once here, you have to push the menu key, it will show an "Advanced button". After that you have to select "Use statis IP"....
5. For your battery life, perhaps you've installed too many apps and they are running in background (and consume power). Don't forget to turn off hardware functions you don't use (wifi, bluetooth, GPS...) and choose a brightness level not too high if you want to improve your battery life.

Thanks for the reply. I have a non rooted DHD running android 2.2.1

Ok.
Did you checked the "Mobile Network" option in the "Wireless and networks" panel ? otherwise it will never work

[Q] Power Efficiency Setting

Can someone please explain to me in details what's the effect of the "Enable power efficiency" setting in the phone please?. i.e. does it turn off wifi or background data? and if so how often then it turns itself on to update data etc..
I am still really confused

I think it moniters your batt ,when it drops under a certain % it auto shuts down those features which cause heavy drain ie wifi mobile network bluetooth and auto sync ,just gives you a little extra time if your not in a place were you can recharge.
sent from my rootin tootin Revolution 6.3.1 DHD

As it self says, it will stop the auto sync for the applications like facebook, mail, google, HTC sense etc. when you are on device 3G mobile network. It has nothing to do with your wi-fi settings. Rather than using Auto Sync on your Mobile 3G network you can alternatively use "sync now" option in Widgetsoid app or plan when do you want to sync your data.

So what's the difference with me turning off "Background data" manually?? If this is the case, this function is pretty much redundant.

its only automatic function. You can set which will be disabled when battery run low. you can fint it in options.

From what I observe at least with Desire HD & the recent 2.3.5 update, this option also affects the way device uses WiFi.
I do not know what exactly are the gradations of shudown for wifi physical or higher levels protocols, but apparently with this option enabled wifi is not so much "instant on" as it is without this option -- if the device is kept off ~10 (approx.) minutes and then switched "on", wifi connection appears only after some time.
Also (I guess as a result of the above), I observe that the device with this option enabled (being switched "off", e.g. during the night), brings up cellular data connection every ~40 minutes or so, I guess to service some data needs (this correlates with com.google.process.gapps activity). Apparently that's because it sees that wifi is really "off", and thinks it's more economic to use cellular data. I would say that average current draw does not change much due to that -- normal "always on" wifi does not take much power anyway.

[Q] Switch off cell / GSM module while keeping mobile data / WiFi

I have found many posts regarding keeping the phone module running while switching off the mobile data or WiFi modules of the Desire but my problem is the other way around. Since I never use my Desire as a phone but only for internet access via mobile data or WiFi, I would like to switch off ONLY the mobile phone capabilities (which drain the largest part of the power over the day). Is that possible at all?
Thanks for any hints!

Yes, you CAN keep WiFi ON while being in Airplane Mode (cell service turned off), but you can't keep mobile data on because it requires cell service in order to work.

Thanks a lot, TVTV. That clarifies it.
All the best

[Q] Delay in connection changeover?

Currently trialing CM9/Franco;
Anyhow, whilst streaming data (SIP/streaming radio/etc) connected to wifi after leaving range of the AP, there's a drop (audio) while the mobile data connection is reestablished (?). SetDNS has a notification pop of the changeover to the dns servers used by the hsdpa ap, so I'm guessing that it's resolving a new address every time that wifi is detached?
Is this normal behavior for ICS/android as a whole? Is there any method to keep active on the mobile data side, wifi on and preferred, so when one leaves the wifi area the changeover is relatively nonexistent rather than the 5-10 seconds at hand? That's enough to kill a phone call
I'd imagine that in some sense something is retained for the sms push, but I'm guessing that's...well, separate.

Of course there will be a break in streaming switching from WiFi to Mobile data, unless the app uses a large buffer and you're on a delay.
When you're on WiFi, Mobile data is turned off. Keeping both on would defeat (or worse) the battery savings offered by staying on WiFi. Both running at once wouldn't help anything.
You're not going to be able to hold a SIP call between WiFi and Mobile data, you won't be able to consistently get a quick enough handoff to do that. Keep in mind that for things like WiFi calling on T-Mobile devices, they needed a completely separate chip in the phone and specialized software to handle a phone call switch from WiFi to Mobile network seamlessly. That just gives you an example of the extra hurdles it takes to do something like that.
