What is the point of Hardwired power for Doorbell 3?

Hello. I recently installed a Ring Doorbell 3 and added a hardwired power supply. The app confirms power is now Hardwired.

The question I have is that the battery was at 99% and it has still drained to 94% in a day. Is this normal? I am confused. Why is it discharging so when connected to an external power supply? I feel, I might as well not have bothered.

These forums seem awash with issues regarding hardwiring the power but no one seems to explain what the issue is.

Your Ring Doorbell is actually is a battery-run device. The hardwired transformer just trickle-charges the battery, but the battery is really what powers the Doorbell.

You can confirm the battery is trickle-charging by looking at the upper-right corner of the Device page, where the Green Battery Icon is displayed with a lightning-bolt. The lightning-bolt should always be there, even when the battery reaches 100%. If it is not charging, the lightning-bolt will be missing.

Most of the time you’ll find the battery at in the high 90’s to 100% range. But under heavy use (frequent Motion-Detections, Live Views, etc.), that percentage can drop until the transformer can catch up. So, at the end of a heavy-use day 94% is not unusual. The battery is just draining faster than the slow charge can replenish it. After the demand on the battery reduces, it should eventually return to 100% again.

I hope this clarification helps you.
