It seems slightly better after a week of use. Almost negligible also after 10.0.2 it may need some adjustment. One weird thing Inam noticing is that the gauge drains much faster 100-> 90 thans the 6S plus. anyone else notice that? Maybe more accurate as 100% can be anywhere from 95-100 the way ios has reported it in the past and the time it takes to go from 100-> 99 is not that accurate either.
