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.

Is the desire always connected ?

Hi,
Coming from an HTC HD1 and HD2, I've just bought my HTC Desire yesterday. And wooow, it's amazing ! Really faster than the HD2 !
It seems that my Desire is always connected to the 3G/EDGE network. How can I see if I'm connected or not ? I've set "enable always on mobile" to OFF, and "Auto Sync" to OFF. But I still see the E icon with grey up and down arrows.
Is there an app to disconnect data after x minutes, if the device is not used ? On windows mobile, I was using WM Long Life to do that trick. I don't know if there is something similar, because I'm very new to Android.
Thanks

Settings -> Wireless & Networks -> Mobile Networks toggle to turn it off. Alternatively, you can use the mobile network toggle widget, from HTC, on one of your homescreens.
About turning off the data after x amount of MB - I use 3G Watchdog. Search for it in the market, it's really good, plus comes with a useful homescreen widget etc etc. lol
Hope that helps.

Grey means they're not doing anything. They turn white when transmitting/receiving.

Thx for the answer. I went through Settings -> Wireless & Networks and turned off the connection. But this option totally prevents the phone from being connected to the 3G network. When I turn it back ON, then the phone automatically connects to the network.
What I want is the phone being able to connect but not permanently.
For example, I check my mails, the phone connects, retrieves the emails, and when no more data is being downloaded, disconnects after xx seconds.
It would drain less battery than being always connected.
I've searched for watchdog, but it isn't what I'm looking for.

If its not transmitting data, it does not use any more power then if disconnected. Don't worry about it.

would highly recommend juice defender. managers disconnection of data at set times to conserve battery.

I have found APNDroid widget to work quite nice. Click to network on, check mail, update everything, then click off. Still not quite what you are looking for, but perhaps a solution. I am currently on 6 month contract in India & the mobile data rates here is ridiculously expensive. 1mb = 40min phone call in price. So it works quite well for the battery drain & cost saving here.

Why use APNdroid when there is a native widget, which does the exact same thing? (add widget, settings, mobile network)

thanks, didn't know that
anyway I use apndroid also, because when I click the Htc gadged, the apn connection is estabilished.
Apndroid adds a suffix to the apn name, thus it's impossible to connect (and pay fees ) if I don't want to

Power Management

Hi,
I'm wondering some things to optimize my battery life, but couldn't find any answers so far:
1) When Wifi and APN both are ON, Wifi will get priority. But the APN-setting is actually still on. Will it drain the battery, or should I always turn APN off when Wifi has been connected?
2) I have set Ultimate Juice (or Juice Defender) to turn on APN every 10 minutes during 1 minute to check for updates. But when I turn off APN, Juice Defender can't turn APN on himself to check for updates. That means that I have to remain APN ON. Doesn't that drain the battery, or is Juice Defender turning APN off on his own way?
3) I noticed that when the screen is off in standby, Android will turn off Wifi and APN. People are saying you should turn off APN and Wifi when not in use, but since Android turns both off while screen is off/standby mode, what's the use of turning both off manually? I think you could even turn them on all the time since they will get turned off when the screen goes black.
4) e.g. You're in a situation without any internet access. Apps like the Friends Stream, or Mail want to check for updates every 5 minutes. the consequence is they can't update because there's no internet connection. Does that action always drain the battery some more?

wtf no one??

under the wi fi advanced settings.. you can set wifi to never sleep... this should mean that your not using the apn connection...

I think apps try to update and if they do not succeed, it will be cancelled. I doubt the apps will continously check for updates until they get a fix. Same with Weatherbug. I sometimes see Weatherbug last updated hours ago, even when I have had internet access for the past hour (I have set it to update every hour). That was when I had unchecked 'enable always on mobile data'.
There are options available for wifi under advanced menu to set it to always stay on, or shutdown after 15 mins of sleep.
There is also an option available to always have data connection on. This will keep data connection alive even if phone is set to sleep.

Do you mean "mobile data connection" everytime you call it "APN"?
There's WiFi and that; two ways to access the net which pull power. WiFi can be disabled quickly and easily through the widget. So can the mobile data network: http://yfrog.com/0ymobilewidgetp
Leaving it to 2G when you don't need 3G or when 3G reception is bad saves much power. I'll need to do more experimentation before I can answer your other qs with assurance.

[Q] [HELP] Xperia ION Battery Drain Problem

Hello
I am New to Sony Xperia ION I am Facing battery Drain Issue. Its draining Tooo Quicky.
Is there any Solution For the Same
Please comment if there is Solution

thanitos said:
Firstly, JD will refer to JuiceDefender
1) You will need JD anything above the free version (Google it)
2) Open JD and go to the "Status" Tab at the top
3) Enable
4) For "Profile" Choose Customize
5) A "Settings" Tab should Appear at the top, if not, close JD and re-open it.
6) Mobile Data can be Enabled or Disabled here as well as WiFi and Location
a) Turn them on and off for what you want, if you want Mobile Data and Wifi to turn on and off on specific apps you can just leave them Enabled.
b) "Schedule" Turning this on will turn on your data every 5m(minutes), 15m, 30m, 1h(hour) or 2h so it can push email and other apps you have set to use data.
c) "Night" this you can use to turn off data while you sleep and for how long you want it off
d) "Apps" You can enable this setting to pick apps that are allowed to use data or turn it off to let them run as they usually do.
e) "Interactive" will pop up a window while JD is in the background and you can pick what JD allows the app to do (will go over more of that soon.)
f) "Configure Apps" We will open this to turn app data on/off on when you have it open, on all the time.
1a) Tap "Configure Apps"
a) "Internet Apps" Apps that use the internet
b) "Configured Apps" These apps are configured by you already.
c) "All Other Apps" These apps usually do not need the internet so they do not need to be configured.
2a) Move to any App under "Internet Apps" and tap it
3a) What do the taps mean?
a) "Enable" This app is enabled, when it needs data it will only use data when you have the app opened.
b) "Enable/Screen off" This app is on and using data while the screen is off and or while the app is opened.
c) "Disabled" This app will never use data
d) "Do Nothing" The app will use data when it needs it, JD won't bother its operation.
4a) Examples
a) "Pandora" I have this app set to Enable/screen off so while I have the app running in the background it will still use data, or while the screen is off it will use data.
b) "Ebay" This app is Enabled, when I open the app and I am looking at it it will use data, but if I hit the home button it stops using data, wont use data while screen is off.
c) "AccuWeather" Disabled, this app will only use data when my Schedule turns data on for ALL items on my phone every 2 hours, it will then update anything it needs to then end data usage for two more hours.
d) "Root Browser Lite" Do nothing, This app will use data whenever it wants regardless of JD rules unless data is disabled.
Using this set up for me, data is always off unless an app needs it that I allow to use it while the phone is asleep (Enable/Screen Off) or I open an app that I have set to "Enable", "Do nothing" or "Enable/Screen off." Not only will this cut back on your data usage or Wifi usage, it cuts back on Awake time, Wake locks, and battery drain from those items and other issues caused by data usage.
Hopefully this helps you with your JD problems and saves you some battery life, on my Ion I have been able to go for two days without a charge with light to moderate use.

Use juice defender also go to your account syncs and shut off any emails and other accounts that sync then go to app store hit the settings button and set to update over WiFi only

here it says;
As such, when I went to *#*#4636#*#* and into phone information, I noticed that the signal was jumping all the time from HSPU to UMTS.
http://forum.xda-developers.com/showthread.php?t=2186911&nocache=1
In my country it only supports GSM. so I changed the signal type from LTE WCDMA GSM to "GSM only". And it is super battery saving now. I advise u to use only the required signal type in your country. More of it suck the battery.

Wifi after sleep?

I have a question. I have "keep WIFI on during sleep" option set to "Never".
When I wake up my phone from sleep after 30 minutes or more of not using it, the wifi does not reactivate itself (it's off, no icon in statusbar), but when I go to settings, it says that Wifi is enabled. Just like in the picture below...
I want to know if this is normal or what? Happens to me on both stock and custom rom.
EDIT :
I fixed this by putting my Wi-Fi frequency band from 2.4 GHz to "Automatic" in advanced wifi settings. Htc and google really need to fix their ****!
I also disabled ipv6 in my router settings, not sure if that helped

Sadly for you, it works as expected for me. I let my phone sit for about 40 mins hoping I wouldn't get a text. Picked it up and the Wi-Fi turned on and connected right away.
Stock Rom (1.91.617.1)
Root
Ex kernel .20 (stock except min perf 0% & GPU medium)
ivicask v17 performance

This is just plain weird for me. Not a real problem, but strange, maybe has something to do with my wifi connection (router).
Thanks for the reply!

Just confirmed that one other guy that just got the phone has the same issue.

I have had the WiFi Frequency Band set to Automatic since I got the HTC 10. I came looking for this topic because of what mine does. When I wake up the screen, there is often a message on the screen "wifi has disconnected", and it will show connected to mobile data in the notification bar. It usually will reconnect to WiFi within a few seconds. But it is annoying, so I am looking for a fix, if there is one. I turned on the setting to keep it on WiFi during sleep a couple days ago, but it didn't change this behavior.
From what I am reading here, this sounds like it is common to the HTC 10 regardless of that setting. I am therefore thinking perhaps the "wifi has disconnected" message is actually left over and still on the display from when I turned the display off? But what I don't understand is that I get notifications such as incoming email and hangouts messages while the display is still sleeping. Unless those are coming via the mobile data connection. Perhaps I should try turning off mobile data and leaving wifi on to test if it still does that, but obviously leaving the mobile radio connection off is not desireable, even if that did help. Does the HTC 10 silently always switch to a mobile connection and turn off wifi whenever the screen is off, meaning that keep wifi on setting is flawed?

No. You probably have "Auto-switch to mobile network" enabled in advanced wifi settings.

Thank you for replying. The only 3 boxes I have checked in WiFi > Advanced are as follows:
WiFi Notification
Show Wi-Fi pop-up
Hotspot sign-in
All the other check boxes are blank.

So I have similar problem. When I leave the house it switches to mobile network just fine. When I come back home it doesn't auto connect until I turn on the screen. My advanced wifi settings are below with basically nothing checked.
I agree this is a serious problem and for me I have no mobile network at home and depend on wifi and hangouts for voice calls.
Just curious what firmware is everyone on? Mine is 1.91.617.1.

This thread discusses it quite a bit, mentioning different settings changes to try.
http://forum.xda-developers.com/htc-10/help/wifi-issues-htc-10-weak-signal-fail-t3368165
I tried some of these changes, and things seemed better today for awhile, until I found out my phone actually wasn't getting the internet over the solid WiFi connection to my network. :/ I had to undo all the changes so I could get back online with it.
