Outdoor Camera Battery Drains Quickly

The outdoor camera battery is advertised as "Lasts up to 3-6 months before it needs a recharge." with the caveat, "Battery life may vary depending on usage, placement and settings." I bought my camera in mid-July 2022 and I've replaced the battery 3 times since then (now mid-October 2022, 3 months). The camera is indoors (in a lobby), so it is not exposed to extreme temperatures; it also times out frequently so it is not running constantly. 

Any recommendations to extend the battery life would be very much appreciated. It's a huge hassle to pull out the ladder every month when I thought the battery should last 3-6 times as long!
