AutoDisconnect

Latest revision as of 05:45, 28 June 2015

This application automatically closes your idle connections (Wifi + 3G/GPRS + Bluetooth) and switches the network mode of your N900 to 2G when 3G is not used, in order for your batteries to last much longer.

Analysis made with one automatic sync (calendar & contacts) running on a unused device every hour using Wifi Access Point : your batteries will last up to 5x longer with AutoDisconnect enabled.

The package is available on the extras repository for the stable version, and on the extras-devel repository for the testing version.

[edit] Interface

To manage the application, you can launch the program 'AutoDisconnect' which is available in Settings > Connectivity. You will find 5 tabs :

• General Screenshot
• Network - General Screenshot
• Network - GPRS Screenshot
• Network - Wifi Screenshot
• Bluetooth Screenshot

[edit] Network Settings

You can choose which connections to check : GPRS (2G/3G) and Wifi. For each of these connections, you have a tab with similar settings.

Ex :

• Interval : 1 minutes after 2 seconds
• Traffic : 2 KB/min

The previous settings means that AutoDisconnect will begin to record the connection traffic 2seconds after its launch. If 2 minutes later, the total traffic is higher than 5x2KB = 10KB, then AutoDisconnect will consider the connection as used and won't disconnect the device. The next check will happen 5 minutes later. Italic text''''Bold text''' [[File:Example.jpglink title]]

[edit] Auto-Switch 2G / 3G-Dual

Please note that this functionality does not depend of the setting "When should AutoDisconnect be active". So if you enable it, it will work no matter what.

This functionality switches the network mode of your phone automatically to 2G when 3G is not used. So how does it work ?

Every time you launch a new GPRS connection, the network mode will be switched to 3G or Dual Mode depending on your settings. After the disconnection, the network mode will be switched back to 2G.

The drawback of this method is that the connection phase takes more time than in classic mode because of the network mode change. So some of your applications which initiates the internet connection (like OMWeather) could believe it to be a timeout. The switch to the Dual Mode required more time than the classic 3G switch, so use it only when you are in a area where the 3G coverage is bad. You can select the duration of the switch, which will depends of your phone/area. The lowest value is the better.

Note : the network mode won't be changed if you are making a call at the same time.

[edit] Possible issues

[edit] Automatic MFE synchronizations (calendar, task, email) are not working anymore

An application which required Internet doesn't connect to Internet automatically if the device is not connected (See Bug 7180), except if the author has manually implemented that functionality. So how to keep MFE or my widgets working?

• In Settings > Internet Connections, Use "Connect automatically" to any network or a specified connection and set the "Search Interval" to some value.
• Alarmed is an application which allows you to run scripts periodically. Install it and create a periodic run of the following script, which will initiate an Internet connection and run a sync :

 #!/bin/sh
 
 dbus-send --print-reply --type=method_call --session --dest=com.nokia.asdbus /com/nokia/asdbus com.nokia.asdbus.sync

[edit] My Widgets are not refreshing anymore

See Automatic MFE synchronizations (calendar, task, email) are not working anymore above.
