Even if the battery is not replaced - Techs should have every device charged to 8-10% when pending a work order to QC.
Any device that has had any type of charging issue whatsoever (this includes problems with daughterboards, motherboards, charge ports and batteries) should be charged to 80% and then allowed to discharge a little to ensure 100% functionality with all power related functions, and QC should charge it to above 97% so that we know that it is charging correctly.
