Hey guys, I am looking to buying a 2 year used macbook pro m3 pro from a seller. Seller is claiming that this macbook is very lightly used. I ran all benchmarks, apple diagnostics etc everything is matching original specs. It has 99% battery health, 70 cycle count but coconut battery shows battery date 1 year older than macbook purchase date. Another thing suspicious is power cycle and power on hours for SSD, refer below details:
