Apple, you effectively BRICKED my iPhone!
Before the "upgrade", I got about 4 days of time in stand-by (no usage whatsoever, WiFi/bluetooth/screen etc off).
After the "upgrade", I got about 16 hours of time in stand-by (no usage whatsoever, WiFi/bluetooth/screen etc off).
(I have tried all kinds of "solutions" and minimum configurations one can find on the net - nothing fixes any of this.)
I know you have an interest in devaluating your customers' phones: You want them to buy new ones. Guess what: THIS IS NOT GOING TO HAPPEN, YOU WILL NOT GET AWAY WITH SUCH FRAUDULENT BEHAVIOR!
You will never get 1 cent from me again.
I also will make sure ALL of my family and friends (including on Facebook, Twitter, LinkedIn) hear about what you are doing.
