Personal Hotspot turns off after 5 minutes

From this in the iPhone User Guide:

Share your internet connection from your iPhone - Apple Support

”When you’re not using the hotspot, your devices automatically disconnect to save battery life.”

1. Is this your corporate/organisation/enterprise/School Management iPhone? Then please contact the system administrator of your corporate//organisation/enterprise/School Management
2. If it is your device, in that case, do you have any profile installed by your corporate/organisation/enterprise/School Management?
   1. Erase the profile added by you If you have installed a profile on your own --> Install or remove configuration profiles on iPhone - Apple ...
   2. Or please contact the system administrator of the organisation who provided the profile to you

A corporate profile installed on your iPhone could potentially be contributing to the inaccessibility of certain features. 

Here's why:

• Restrictions: Corporate profiles can have restrictions placed on apps and functionalities. These restrictions might be limiting some activity, causing it to be unresponsive or quit.
• Managed Apps: IT departments might deploy specific navigation apps through the profile, potentially blocking certain functions or features.
• Security Settings: Corporate profiles often have stricter security settings that could affect app or function behavior. This might be causing unexpected behavior of an App or functions.

Here's what you can do:

• Check with IT: The best course of action is to contact your IT department. They can explain the restrictions set by the corporate profile and see what is affected. They might be able to adjust settings or suggest alternative apps or features approved for corporate use.
• Look for App Conflicts: See if your IT department uses a different app through the corporate profile. Conflicting apps might cause crashes.

Additional points to consider:

• Even if the profile isn't directly affecting the function, it's still a good idea to check with IT. They might be aware of similar issues and have workarounds.
• While troubleshooting, make sure you prioritize safety. Don't fiddle with your phone. 

By working with IT and considering these possibilities, you can hopefully identify if the corporate profile is the culprit and find a solution that allows you to use the iPhone to your liking.

Hotspot is a feature provided and controlled by your cellular carrier.

You need to get in touch with the customer support folks at your carrier to ask about Hotspot issues.

Old issue, new issue, what changed...?

I use Hotspot for 100% of my Internet connection for the last 6 years...

What I can say the behavior of HotSpot connection seems to change with each and every update/upgrade; sometimes better, sometimes worse but never consistent.

I have never encounter your issue however, so I am suspect.

For Wi-Fi with cellular backhaul, consider acquiring a mobile wireless hotspot — MiFi, etc — from your carrier.

These devices provide local Wi-Fi, connecting to the internet via a cellular 4G or 5G carrier network connection.
