APM Only works after being plugged in

I just recently got these APMs, and I've been through 5+ factory resets this week alone. It randomly stops working after being disconnected and I have done the following that I've found online

• Resetting (Crown + ANC/TP button)
• Charging AND being near a charging phone to update firmware (This has NOT worked for me.)

Charging until the amber light turns bright green

I suspect it is a firmware issue, and the firmware is stuck on 4E71 (2022)

I've literally done everything, and I hate to carry a lightning cable around with me. I don't have that much money on me to afford a repair since AppleCare+ is expired on my device.

When I press/hold both buttons, or one button at a time, it does not show any light indicator. Answers appreciated.
