?Capacitive buttons (?back? mostly) sometimes unresponsive, have iShieldz protector installed
?Screen a tad too sensitive at times (set on high), in normal mode ?back? button not sensitive enough
?Occasional screen lag or jitteriness while scrolling or when returning to home screen
?Noticing ?Resuming? is more prevalent on 830 compared to my 1020/Ativ S
?Lumia camera on par speed-wise with my 1020 yet was expecting it to be slightly better, using the MS camera makes it comparable to my Ativ S
?Camera physical button overly sensitive, somewhat better w/gel case on but still find myself constantly launching camera
?Battery slow to charge, takes about 2-2.5 longer than my 1020 or Ativ S
?Battery falls of rapidly from 100% charge by 5-8% within first 20-30min, seems to balances out after that
?Battery drain under medium to heavy usage is 1.5-2 times faster than that of my 1020/Ativ S
?Slow to shutdown, takes approx. 4-5 times longer compared to my other WPs, 1st 1020, 2nd Ativ S and lastly 830? Latter is the faster of the three on start-up but only by a smidgen
