First thing I noticed is that one can't really know when the battery is fully charged as it was done before, as the upper small icon doesn't change from a lightning to a plug. I kind of found a workaround for those who wanna actually make sure it's 100% charged. Go into Settings, General, Use and go all the way down. If the "Use Time" timers have gone back to 0, then you're good to go. P.S: I know a lot of you don't care about it, but searching the forums I found quite some people asking about it.
