Stick up Cam battery drained from 100 to 28% in 23 days whilst other cams are fine

I bought 3 stick up cams batterys about a month ago and they been good. However one of the cams has had terrible battery life and is down to 28% and averages 8 motions a day with half motion sensitvity and low notifications and no additional features on. The other cams are fine at 62% and 53% which both average 10 motions a day with 3/4 sensitivity. I don't understand why this is happening as it has lower motion than the others and seems to be a faulty battery.
