My iPhone 15 has been restarting automatically approximately every 3 minutes. It also heats up near the volume buttons.

You may try some of these steps. Please check after each step...

1. Having too many apps open may cause this issue, as RAM is being used by other apps, leaving less memory available for proper rendering. Close an app on your iPhone or iPod touch
2. Overloaded system: Too many apps running in the background can cause stuttering. Refresh content in apps you're not actively using on ...
3. Storage issues: Low or fragmented storage can slow down the camera. --> Manage and Clear Storage on your iPhone a… - Apple Community
4. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
5. If you're using a VPN, disable it and check if the error goes away. Go to Settings > General > VPN & Device Management and turn off any active VPNs. Disabling a VPN only from the iPhone settings may not completely turn it off. To fully disable it, you need to switch it off from the VPN service provider’s app or remove the configuration profile they installed. Only then is the VPN truly off, which can help if it’s causing issues with cellular or Wi-Fi connectivity.
6. Reset Network Settings: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings: Only network settings are removed.
   1. When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
   2. To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or remove configuration profiles on iPhone in this guide.
   3. To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.
   4. Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.

7. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
   4. 
8. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.

It is either the battery or the logic board.....possibly both. Hopefully,, it is just the battery since a logic board replacement will make you wonder whether the money might be better spent on a new phone.

Make an appointment at the Apple Store or take the phone to an Authorized Apple Service Provider (AASP). You can find a list of authorized shops in your area using this link:

Find Locations - AppleAppleFind Locations

The back glass was replaced by a third-party repair shop.

Unfortunately, that may be an issue, since Apple may refuse to look at the phone if it has been modified by an unauthorized shop. Worth a try, but you may be taking the phone back to a third party shop. who will not have access to genuine Apple parts.

Good luck.

It could be a variety of things. Unfortunately with the initial unauthorized repair, you are left having to deal with a third party repair shop again and with any service warranty that they provide. If you don't trust the first one you used, try another and see what they say. You may end up deciding that it is not worth the risk in repair and spending more money on the device, where it could be spent on a new device.
