Poor Battery Life

i’ve recently purchased 2 ring security cameras off of amazon. i charged the battery up fully before use & have them both set on the same motion setting. Each camera sees very little motion activation each day however the front camera battery has gone down to 10% in just over a week (droppeed 10% in one day) i’m guessing this is an issue with the battery itself or could it be something else ?my question is i’m i better off going through amazons returns and replacing the full camera or getting a replacement battery sent out ?Any info would be greatly appreciated
