Just wanted to give a little more insight into the short battery life on the latest generation SmartThings motion sensor. I have at least 8 of these and found battery life was terrible. When I mean terrible I was getting 2 weeks if I was lucky. See SmartThings Motion Sensor poor battery life
The ones I have installed are a mixture of v11 & v14. Back when I was having all the trouble I purposely update some sensors to v14 (through SmartThings) to see if there was a difference in battery life. At that time, mid 2020, I found no difference. Battery life was bad for both versions. I even converted a few of them to use dual CR123 batteries and I was lucky to get a month. Again, terrible. People were sighting poor mesh for which I doubled the amount of repeaters and was still having the same problems.
Sometime last last year 2020 the poor battery life problem went away. It wasn't due to firmware and it wasn't the zigbee mesh or changing anything related to devices. The only thing that changed was hub updates. I don't know what version it was but I am still on the same batteries since Jan/Feb and they still are going strong. I hope this helps
