Battery life lasting 3/4 days

Hi, We purchased a Ring video doorbell back in the summer. The battery life lasted about 4-6 weeks , however since then the battery life was becoming shorter, I’ve shortened everything I can see that could reduce the battery usage, but now I’m only getting approx 3 to 4 days , as an example I replaced the battery on Tues 100% and now it’s Thurs it’s reduced to 39% already. Is there anything else I can do with the battery as a hard wired wouldn’t be easy to do. Ps I have 2 batteries I rotate with still the same issue, so it’s no the battery. Many thanks
