Just done upgraded from iOS 13 to iOS 13.1
Hope fix battery issue
1 more thing notice in iOS 13 is Siri become more re-tard than before
It totally cannot catch my slang
Hopefully it become normal or smarter in iOS 13.1

Siri seems a bit better
But still forgot everything I taught her in iOS 12
Upgraded from iOS 11 to iOS 12 Siri remember everything but forgot everything in iOS 13
Wasted my precious time to teach the retard Siri

when you talk to siri
it will learn from what you said
if it's wrong
you can type it
so, siri become smarter by means of can recognize your slang
after upgrade ios13
it totally went back to 3 years ago
it cant recognize my voice and gave stupid wordings
all my past 3 years efforts gone
perhaps you less using siri you din realize it
