     <string name="baterry_consumption">In my personal tests the main reason for high battery consumption of OpenVPN are the keepalive packets. Most OpenVPN servers have a configuration directive like \'keepalive 10 60\' which translates to a keepalive packet from client to server and server to client every ten seconds. &lt;p&gt; While these packets are small and do not use much traffic, they keep the mobile radio network busy and increase the energy consumption. &lt;p&gt; This keepalive setting cannot be changed on the client. Only the system administrator of the OpenVPN can change the setting. &lt;p&gt; Unfortunatly using a keepalive larger than 60 seconds with udp has problems with some NAT gateways which terminate the state for a connnection after a short timeout (60s in my tests). Using TCP with long keepalive timeout works but has the TCP over TCP problem. (See &lt;a href=\"http://sites.inka.de/bigred/devel/tcp-tcp.html\"&gt;Why TCP Over TCP Is A Bad Ide&lt;/a&gt;)</string>
