There is a fixed timeout of 12 hours after which your VPN connection is disconnected. There is also a non-activity timeout of 20 minutes which takes effect if no network traffic passes for 20 minutes.
Is there an automatic re-connect feature?
An auto reconnect feature is enabled, but it is only in effect within a session with a duration < session timeout (12 hours). So you can't be connected more than 12 hours without manually re-connecting and re-entering your credentials. This is by design and was explicitly asked by security.
Can I connect to the SLAC VPN using my mobile device, e.g. smartphone?
...
Stanford university is using different VPN protocols and technologies, so the SLAC VPN client can't be used to connect to Stanford through VPN. But when connected to SLAC VPN you can reach Stanford ressources as if you were in your office at SLAC.
If you are a SLAC employee/user willing to access SLAC ressources you should use SLAC VPN, if you are a Stanford university employee/student you should use the Stanford VPN client provided on http://itservices.stanford.edu/service/vpn.
