We appreciate all of the troubleshooting that you have completed to this point. We recommend having your iPhone serviced. You can locate your service options here: iPhone Repair & Service - Apple Support

"Before you bring in your device
Follow these steps before you take your device to an Apple Store, Apple Authorized Service Provider, or carrier. If your device won't turn on or respond, finish as many steps as possible:
- Back up your iOS or iPadOS device.
- Have your Apple ID password ready. For some repairs, you'll need your Apple ID password to erase your device and turn off Find My.*
- If your device needs battery service, make sure that the battery percentage is at 30% or less when you bring it in, if possible. This will save time on your repair.
- Turn off Apple Cash and remove your cards and passes. If your device is unresponsive, sign in to appleid.apple.com, select Devices, then select the unresponsive device. Under Wallet & Apple Pay, select Remove Items.
In Japan, if you use a Suica, PASMO, or ICOCA card with Apple Pay, erase your iPhone or remove the Suica, PASMO, or ICOCA card from Apple Wallet. If your device is unresponsive, sign in to appleid.apple.com, select Devices, then select the unresponsive device. Under Wallet & Apple Pay, select Remove Items.
If you haven't already, check whether you need an appointment before you go to a service location. For example, schedule a Genius Bar reservation before you go to an Apple Store. When you go, remember to bring these items:
- Your sales receipt (if possible), in case your service requires proof of purchase
- Your device and any accessories that you need help with
- A form of personal identification, such as a driver’s license, passport, or other government-issued ID
* If you're unable to turn off Find My, Apple might not be able to service your device. This policy is in force to prevent unauthorized persons from servicing your device without your knowledge. If you don't remember your Apple ID and password, go to iForgot.
