Being asked to change password every day for last few days and when i go on mail on my iphone, it asks me to change it again. Why?

That is a glitch. Ignore the prompts.

  • Why has my battery on my iphone been draining the past few days? I have a 16 gb iPhone 6 and for the past three days the battery has been going by really really fast, even when it's asleep and in my pocket. I tried deleting apps but nothing works.
  • Why does my iPhone go through so much data in a few days? I have an iPhone 5, which is running iOS 9.1, and I seem to be going through 1gb of data in just less than a week. The only Internet browsing I do on the phone is a bit of Facebook each day (I also upload pictures to Facebook from time to time), and a few Google searches each day. Could it be the Facebook app that is eating so much data? Or could it be something else?
  • Why does Apple keep making and release new iPhones every few months? Like why did they make then Iphone 6 just make and release the iPhone 6 plus, iPhone 6s, iPhone 6s plus? What is the point of apple doing this doesn't apple not have enough money? It's like if you have windows 7 and you upgrade to windows 8 then they come out with windows 8.1 then a year later they come out with windows 10 like why i already upgraded why do i need to upgrade again?
  • Why am I being asked for card payment to update and download free apps (iPhone)? I've reviewed other people's comments re the same problem on apple support and the only answer was to use the 'none' option when selecting card type but no such option is available?
