Doorbell battery life

My ring doorbell (gen 2) battery life last 2 weeks only even after charging it fully each time it drains down & minimizing its sensitivity sensor to the very least level. I had the doorbell for almost 2 months, had to charge twice now in addition to charging during the install. What’s a better option on improving battery life? Ring products that are battery operated have very short lifespan. It won’t make sense having the camera and the need to charge every 2 weeks when I’m away for a month.
