Been doing some testing and here is what I have come up with...
Started with Fresh flash (Feb22 Std) with nothing installed
1) Installed the attached battery monitor to check settings
Battery DisChargeCurrent 250-285 mA
ChargeCurrent 450 mA (usb 2.0 lets me know quick charge isn't working - should be 900+ mA)
2) Installed the attached nuebattery2 driver and enabled quick charge settings and don't round percentage to re-enable 1% reading and reset
Battery DisChargeCurrent 250-285 mA
ChargeCurrent 922 mA (now it is quick charging)
3) A lot people are supecting that the battery issue is related to bluetooth whether you are using it or not so I installed the SprintStockBTDlls file from this thread

Enabled BT, reset, disabled BT...
Battery
DisChargeCurrent 164mA (plugged into activesync via usb 2.0)
Battery DisChargeCurrent 46mA (unplugged)
To me this is a substantial difference in discharge and charging amounts.
I think this warrants more testing.
