6 months since a battery complaint plus new issue?

Frustrated with my battery life. I just revisited old battery complaint posts. UUUGGGHHHHH. Also, there is some metal component loose in my device that rattles with any movement.

Has anyone experienced this? Near the time this started, my camera was malfunctioning but the camera has since corrected. Nothing else, within my ability of use, seems to be off although the rattle itself is an issue. I have placed an email with the company. Attached a video of me shaking the R1 lol
