How do i figure it out what app use the cellular data in standby mode?

How do i figure it out what app use the cellular data in standby mode? I disabled the cellular data for 3 days, and my battery last longer. I don't use push notifications, neither location services. I'm not signed in in skype or any IM app.

Do you use push email? Do you have accounts that have synchronized calendars associated with them? Those features will still use cellular data in the background as the receive mail and send or receive calendar updates.
Some notifications, like push notifications from Facebook and other social networking sites may use cellular data in the background. Basically, any automated data task like those may use cellular data when the phone is in standby (note that wifi would be used if available when the phone is active, but wifi turns off in standby and all data goes through the cellular data connection).

I can't work out what apps use the internet. Please help

I cna't work out what uses the internet and what doesn't on my iphone4 please help????

Settings>WiFi>Off...then Settings>General>Network>Cellular Data>Off...then start launching your apps, those that require a data connection either won't work or will generate an error message. You could also accomplish the same thing by putting your phone in Airplane Mode.

HT1711 How do I update new versions of Apps using the new iTunes?

Good day all. I am having problems downloading updated versions of some Apps using the new iTunes. How do I update new versions of Apps using the new iTunes?

You can go back to the old view with the left-hand sidebar via View > Show Sidebar (if you are on windows then alt-v should show the View drop-down menu) - which is what I'm currently doing as I'm familiar with that way.
Or, on the new view you can click on the library type at the top left and select Apps and then Check For Updates at the bottom right of the screen. When you've downloaded the updates to your computer, click on Library top right to go back to your library view from the store, then select the iPad (top right) and Sync at the bottom right should then copy the updates to your iPad.

What is using my cellular data?

iPad 2, freshly reset, recently updated to iOS 6.1. The only installed app is Skype, which is set to go offline after 60 min. Location services are disabled, cellular data for Appstore ist also disabled.
I now had the iPad lying around for two days and according to my cell bill on both days around 3 am it used the internet, yesterday 15 kB, the day before 140 kB. This is a problem because in my cellular data plan any day where I use cellular data, I have to pay 2,50 €.
I know that I can disable cellular data completely, but I would rather have the iPad just don't use it when it's off (for more than an hour, when Skype shut down).
What can also cause this traffic?
Or are there any apps to block all applications from using cellular data except Safari and Skype?

If the phone is asleep and not connected to an external power source, it will use the cellular data connection for mail, push notifications, etc. This is by design. To keep the WiFi radio on with no external power source connected would drastically reduce battery life. Of course, it appears Safari and App Store are using WiFi, because they can only be used interactively... Mail will use WiFi as well IF the phone is not asleep and is connected to a WiFi network.
If you turn cellular data off, the phone will power up the WiFi radio to poll the mail server since there is no other option.
You can set mail to retrieve message manually instead of using push or polling. This will ensure that pulling down your mail can only be initiated by you, and if you make sure you have a live WiFi connection before doing so, it shouldn't be a problem.
Since you've seen a sharp increase in the last month, I'm assuming you're either getting much more mail than you had been previously, or you've been getting more 'large' messages or both.
I don't know what kind of data usage you're used to seeing or what you consider a sharp increase. Is it pushing you over your cap?

How to find out what is using the native heap of a process running a JVM?

Hello,
I am not sure where to post this question so I am starting here.
I am troubleshooting a Java application using some native calls (32 bits Java running on Solaris 10). The size of the process (as reported by prstat) is slowly increasing day after day.
The size of the 'Java heap' is fixed at the start (-Xms and -Xmx are set to the same value on the command line when launching the Java app) and the GC is workling fine. No memory complaints from the Java side of the application.
It is the size of the 'native' heap (as reported by 'pmap') that is increasing:
root@mas01 # pmap 5382
5382:/apps/java/bin/java -server -Xms207M -Xmx207M -XX:MaxNewSize=24M -XX:N
00010000 64K r-x-- /apps/jdk1.5.0_19/bin/java
0002E000 16K rwx-- /apps/jdk1.5.0_19/bin/java
00032000 3896K rwx-- [ heap ]
00400000 389120K rwx-- [ heap ]
18000000 2784K rwx-- [ heap ]
DCAF4000 48K rw--R [ stack tid=169 ]
DCBF6000 40K rw--R [ stack tid=161 ]
DCCF8000 32K rw--R [ stack tid=160 ]
My first reaction was to search for a memory leak. Found a minor leak in the JVM with the ::findleak function (called within the mdb debugger). Upgraded to a later release of Java 5 (Java 1.5.0_19) where the leak is fixed but the heap is still increasing.
Many parts of the process allocate memory in the native heap. The JVM itself, the native calls made to a C++ library part of our Java application and maybe also some 3rd party software.
I would like to know what is the best way to find out what is consuming more and more memory in the native heap. I started looking a DTraces but I am new to this. I also thought maybe the Solaris Perftools might be of use but I never used them. Before plunging into a tool more or less blindly, I am asking for advices on how to tackle this issue. Can someone recommend a tool/method to see what is allocated in the heap?
Regards,
Stéphan

After googling a lot I managed to run my application with libumem, generated a core file and succeeded to find some leak with mdb even if ::findleak reported nothing.
Does anyone knows if the ::findleak (you need libumem and mdb) is supposed to find leak in the native part of the memory and a Java application using the JNI interface?

How to pass command-line options to app using the "open" command?

I am using jedit, and since I'm doing a lot of stuff in a shell, I'd really like to launch it from the command line as though I'd opened from finder, so I wrote a script that contains this:
open -a /Applications/Jedit.app "$@" &
This works well for everything except NEW files, where I get this error:
2007-02-16 19:29:48.072 open[1032] No such file: /Users/millerti/projects/ateon/new_file
Is there a way I can override this?
So, it occurred to me that I might try running jedit directly this way:
/Applications/Jedit.app/Contents/MacOS/jedit -- "$@" &
The trouble is that this suffers all sorts of weird problems. For instance, if there's already a jedit running, it launches another one (despite the fact that -server is default). Moreover, the file it opens, existing or not, is not the one I specify. If I'm in ~/mydir and I open ./myfile, jedit opens instead /Applications/myfile.
Obviously, I'm doing something wrong. Can someone help me figure out what open is doing internally so that I can launch jedit compatible with how open does it so that I can both open existing files and create new ones the same way from the command line?
BTW, I can make more complex script.
Also, if this isn't the right forum for this, can someone tell me where would be a better place to get the question answered?
And I'm not expecting to get jedit support here. This isn't a jedit problem because it's behaving correctly.
Thanks.

Applications rarely take command line arguments. I don't know anything about Jedit, whether that is an exception, but you are not sending an argument to Jedit with the open command. The file name on your command line is an argument to the open command. The open command says "open this file with the specified application". The application doesn't see the argument. It sees the file exactly as if it were opened from the Finder. That's why naming a non-existent file doesn't work.
What if you open Jedit with no file, create a new document in the application. (Again, I am not familiar with Jedit.)

When i download software, then go to the download window and click on the file, it is aking me to open it with a launch application. how do i figure out what app to use. ex; downloaded a new version of java, what app do i use to install?

I have two iPhones on my iTunes account. How can I find out what apps go to which phone?

I have two iPhones on my iTunes account. How can I find out what apps go to which phone?

I don't believe that there is a way to do that. I would sugest using automatic downloads to keep your apps synced across both phones. You might also want to note that just about any app you have ever download will be available for free download via icloud.
Wish I could be more help.

How can I find out what apps are on my step daughters phone without the phone?

How can I find out what apps are on my step daughters phone without the phone? She is on my phone plan but does not live with me and I am concerned about the apps she may be using.

baniville108,
Thank you for reaching out to us. We certainly know the importance of being able to know what options are available with your device. With apps on devices, thoses are specific to the phone itself, so there is no open forum to view what apps are downloaded. The only option would be to physically review from the phone, or if you have the same Apple ID you can log into it and view from there. Please let us know if you need anymore assistance.
Thank you,

How do i find out what app was deleted by mistake on my iphone 5?

How do I find out what app was deleted by mistake on my iphone5?

Do you mean that you deleted an app by mistake and you don't know which one it was?
Look for it in the Apps section of iTunes. If you used iTunes to sync your phone, just choose Install next to the app, then resync.

I have an app using data every three hours...how do i find out what app it is?

I have an app using significant amounts of data every three hours. How do I find out what app it is?

I don't know what you're basing the 'every three hours' thing on, but if you're looking at the bill from your carrier, remember that data usage is not reported in real time. It's reported in batches. It's more likely that the data usage is being 'reported' every three hours.
Look in Settings>Cellular. You can see how much data each app has used and control what's allowed to use cellular data and what's not.

If i delete an app, how can i find out what app did i delete

My son delete an app. Can I find out
what app did he delete?

Not exactly.
You can open the App Store app > Purchased > Not on this iPad and you will see a list of apps you own that are not installed on the iPad. I believe the newest ones are listed first.
