Doorbell 2nd Gen not charging via hardwire

I had the 1st Gen doorbell for years without issue. Hardwired to the doorbell wires and always stayed charged. Never had to remove and charge via usb. Upgraded to 2nd gen and now I have to remove and charge monthly. Same hardwires. I've lowered all settings, sensitivities, alerts etc. as low as can go but still keep the thing useful. Ring support has not been helpful, just pointing me to the generic website help sections. I've tried all that several times. I won't call and speak with someone so they can walk me through the same steps for 30 minutes with same results. Just send a replacement. I've been a subscriber for years with four active devices. Jeez.
