No, within reason obviously, if you phone gets too hot to touch then that would be a concern. If the temp is just hotter when charging then no, this is normal behaviour for a battery when charging.

That is their ideal operating and charging range. Lithium batteries don't necessarily like being fully discharged or canstantly being charged to 100 percent.
