I have used the original charger, aftermarket chargers, car chargers, different batteries... you-name-it. Exact same results. My first phone was fine; it's the replacement that has been problematic. A colleague who works in the professional electronics (broadcast TV) has the same phone and believes there is a problem with the charging circuitry.
I recently installed Battery Doctor and Save Power apps which constantly report that the phone battery is draining quickly with 100+ apps draining it (even when every app has been turned off.) I have to use the cumbersome app to optimize all day long or it drains in 6-7 hours, much less if using Waze or actually talking on the phone!
