Got the same problem here, but itās more than just push email. Immediately after applying the 8.0.2 IOS update, push email stopped. Donāt get anything immediately any longer. Emails on my work Exchange account are taking an hour or more to reach me. My office hasnāt touched the Exchange server configuration in months, and thereās been no change in how my Blackberry has been receiving emails on the same account (Blackberry is running that same account on BIS, so same 15 mins or less schedule applies to that device). Wasnāt sure if that was happening with the 8.0 update, but push email is definitely badly broken with 8.0.2.
But the problem is not limited to push. All of my POP3 and IMAP4 email is also delayed an hour or more. No settings have changed, I still have my POP3 and IMAP4 accounts set to 15 minute polling. iPhone is not polling. POP3 and IMAP4 are also badly broken.
And thereās one more symptom. Since applying IOS 8.0.2, battery life has dramatically improved. Thatās a symptom of a very bad thing. Any time Iām home, I manually turn off carrier data, since I caught Verizon billing me for data usage that should have been passed for free on my home Wi-Fi system. Very often now when I wake up the device with Safari active and try to load a web page, Safari alerts that it needs carrier data and stops. Thatās because thereās no Wi-Fi signal (icons confirm). Thereās no Wi-Fi because apparently IOS 8.0.2 is turning off Wi-Fi, which shuts down all internet connected apps. Push email canāt work if thereās no data service active. Wow, isnāt that clever.
But thereās one more bad side-effect this āpower saveā nonsense will have on cell customerās accounts. If thereās no Wi-Fi active on this device when youāre within range but the device just woke up, but you havenāt turned off cell carrier data, guess which system will be billing you more for data when you thought your home Wi-Fi was taking care of business.
