IPad mini with retina very slow and battery drains fast

Question

my ipad mini 2 is only ten months old. After getting the iOS 8 currently on ios8.0.2, wifi internet speed is only 25% of the normal speed (compared to what my imac tested), battery drains 1% every 3 minutes or so. All of these after I restored it to factory setting per Apple support suggestion. is there any fix for this soon? why is the issue only affecting some but not all users? Is there anything I can do for my ipad? I have only been using it lighty (have installed like less than ten app's) but this is still very frustrating.

You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.
