Doorbell 2 - does NOT CHARGE battery properly when hardwired!

I'm really tired of spending so much time on this but I have come to the conclusion that hardwired Ring Doorbells just don't work. I have a 2nd edition (2020 version) that I've fought with for 6 months. The voltages are all good, the existing chime works, the signal strength is good, the battery is fully charged when I install it...and then within 3-4 weeks, the battery is dead. The battery actually lasts longer if it is NOT hardwired (probably because the ring doesn't light up all the time). I called support, reset it, tried all their suggestions, they actually sent me a replacement doorbell...and the new one does EXACTLY the same thing. These forums are FILLED with people having the same problem and there's nothing but deflections from Ring...your voltage is wrong, it's too cold, you have too many events, etc, etc, etc. The fact is...this thing just doesn't work. They probably will never admit it, but I don't think their design works. That's why they just released a new Ring Doorbell Wired model - it has no battery! That suggests to me they finally figured out how to make something work hardwired - but the whole wired/battery combination just doesn't work. The best doorbell - the Google Nest - doesn't have a battery either. Not just a coincidence, I think. I just wish I hadn't wasted dozens and dozens of hours over the last 6 months trying to make this work if it doesn't work. Just admit it already!
