In my experience, it depends how on the specific cell’s holding voltage characteristic. I have tested brand-new Panansonic (many types) and the Soshine protecteds. Although the iCharger terminates its charging at 4.2V, when the cell is taken out, seldom did I get, maybe once only, a cell that held the 4.2V for more than a few seconds. They always settle to 4.19/18/17/ . The Soshine 2900mah I tested settled at 4.14 before I discharge-capacity tested it, yet it even got 2915mah at 3A discharge rate. So I don’t worry much about the starting voltage personally. This is the review I made:
