My guess may be the voltage sag is intentional and helps to lessen the electricity dissipated in the wall charger itself. There isn't any require to keep up specifically 5V within the charger output once the battery is at a minimal charger level.
Men and women normally speculate simply how much power their charger is losing when it's idle, and when they must unplug their charger when not in use. I measured this "vampire" power use and found the chargers diverse by over a factor of 20 of their idle ability usage. The Samsung rectangular charger came in ideal, making use of just 19 mW; this was so minimal when compared to the other chargers that I calculated it once again a distinct way to make sure I hadn't designed an error.
