is company portal app quicker and resolves and helps us the device to be checked-in at minimum time period like less than 8 hours as its default time period for all the devices?

@Vinod Survase, Thanks for posting in Q&A. In fact, the Company Portal app does not have the ability to change the default policy refresh intervals for devices managed by Intune. The default policy refresh intervals vary between platforms and are estimated to occur about every 8 hours. But users can manually check for policy or profile updates at any time by opening the Company Portal app and navigating to Devices > Check Status or Settings > Sync. or Sync under Accounts>Access work or school, the account> infp >Sync.

After researching, I find there's PowerShell script to do the sync. You can read it as a reference:

Note: Non-Microsoft link, just for the reference.

Hope the above information can help.
