IOS 11 BATTERY LIFE (not a DJAY problem)

Just wanted to let other DJ’s beware, I normally use DJAY for weddings n such with IPAD and it has NEVER , died before the gig was over even after 6 hours, its not DJAY that’s running it down, but something with the update, I have done all proper procedures according to Apple to help battery life, non has helped, hopefully a future update from this will help, once again this isn’t a DJAY problem per say but wanted to let other dj’s Know that sort of rely on it, fortunately, I had a pc with DJAY windows that worked great, for a backup, (even after the Windows new feature update) but just wanted to send an FYI, the battery is life is horrible still, on the IPad Air 2, even after 11.03
