The unstated problem with a battery that "just gets you through the day" is that the battery endures at least 1 charging cycle every 24 hours, probably more than that on average. Li Ion batteries are designed for anywhere from 400-1200 charging cycles over their life span. Considering that the battery isn't removable, and if the charging cycles life span is on the 400 side, that is also a concern to me. The battery dies 35 days after the 1 year warranty expires? sorry, it's not removable, buy a new phone unless you have insurance.
