Battery health is on 93%. Is that normal?

If you use most of the charge every day then 7% loss after 7 months is not unusual. My iphone 7 is 85% after 13 months but I use more than a full charge each day on the forum. Get Apple to replace it at 79%, not a back street butcher.

You did well to find an iphone 7 brand new last October. The last ones were manufactured at the start of 2020.

Best iphone of the lot. Metal back.

That is an old device and is probably a replacement battery.

They manufactured them for reseller market into 2020.
