My ring doorbell is hardwired but showing a low battery why?

I have the same issue with my ring doorbell 2. It’s hardwired and I have been using it one and a half years now without an issue. Two days ago I received a low battery notification. It’s not charging the battery since then. Is it because of new features or firmware update?Any idea how to fix it…

Update: I replaced the battery with a fully charged one and it still shows %2

Just wanted to throw in my two cents agreeing that this seems like a firmware issue. I made a post since I couldn’t find anything exactly like this thread, but now that I’ve found this thread, I’ll put this here with the troubleshooting I’ve done.


I have a Ring Video Doorbell 2 that’s always been hardwired to a 20VAC transformer since I got it in 2018. Until the past couple months, I have never had to charge it, but recently the battery has been draining even without any change in the average number of motion events.

If I take out the battery and plug it back in to “restart” the doorbell, it starts charging again slowly at a rate of about 8-10% charge per day. However, seemingly at random it will start draining quickly again at a rate of 15-20% per day. One time I tested the doorbell, it got back up to 44% before it started draining. Another time it got all the way up to 100% before it started draining again 1-2 days later.

It seems like maybe there’s a software bug that randomly triggers and then goes away temporarily after a reboot.

At first I attributed the battery drain to the cold since it first died when it was in the 10s and 20s Fahrenheit outside, so I took it inside and charged it, but now that the weather has warmed up, it’s still having the same issue. I also ended up doing a factory reset after I saw it had drained after the first time I charged it.

I connected the doorbell directly to the 20VAC transformer and bypassed my doorbell chime to make sure that’s not causing an issue. I measured the voltage from the transformer at the connections to the doorbell at 21VAC. But still having the same problem after doing that.

Hey ring, let’s fix the problem! Everyone seems to be having this issue and it’s super annoying.


Ordered and installed Doorbell 3 Plus April 10 2020.
Have not had any issues until April 5 2021.
All of a sudden battery will not stay charged, no device changes, changed battery, fully charged, checked hardwired wires, getting 19.8 Volts. Battery still dies after a few weeks.

Same - I have a 1st gen, worked fine hardwired for two and a half years, then a few months ago, it started using the battery power. How do we fix this??
