Is this normal? I am confused. Why is it discharging so when connected to an external power supply?" 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.
