Battery Drain - Recharge

[Navamuel]

Hi 

I have the Arlo wire free, it’s connected to the old doorbell wire over the last 6 months, all working ok always stay charged at 80%.  There hasn’t  been that much use but the battery last weekend not sure why it went down low,  I got a notification that battery was  at 15%, so I recharge it using the plug and cable, I been keeping an eye on the charge during the week, it went down to 80% I could see on the app it started to charge again as wired from the old doorbell,  but overnight it went down from about 65% to 40% ,(I don’t see any notifications of movement of any type) now a few hours later is down to 35%, hasn’t charge anything at all during the day. 

my question is what will the best setting be to allow charging ASAP to the full or 80% ? to try to help I lowered sensitivity to 50%, I also made smaller the activity zone (even that I don’t get that many that are not real movements), any other ideas? The battery only charge with its idle according to the instructions. 

the doorbell was purchased Jan 2022, could it be that battery health starts to deteriorate past the 12 months

to force us to buy a replacement battery?

I suggest checking the power at the doorbell.  It is possible that the transformer is failing, or that something has happened to the wiring connection at the doorbell.

Disconnecting the wires from the doorbell would be a good test.
