My replacement battery is showing an 8% capacity loss after 1 charge cycle. I find that pretty %#*@ steep but I know nothing about batteries besides checking the capacity and cycle count. The charger I’m using is still the same one I got with the phone.

Run a few cycles first to see if the capacity stabilizes. Battery capacity is subject to manufacture tolerances, temperature, measurement inaccuracies and a lot of other factors, a few percent is totally normal.
