hello friends..
I have one UPS for PC. it will give power for full load up to 30min without any supply power. when i use that power for mobile charging, or some light. Even it has full charge, It will automatically turned off after 5min. can any one tell me the problem.

give details how much load you are giving to ups, some ups having a no load cutoff option if the load is below a specified range it will go to off state

As Raju said it is UPS no load shutdown. Check the below thread:

[rajudp]

it is added as an extra protection for ups so i don't thing you can turn it off
