Opinions about downloading IOS7?

I have been putting off downloading IOS7 to my iphone because everyone I know who has downloaded it says its horrible.apparently it uses up loads of the battery life. Is that true? What are the pros and cons of IOS7 and what's your opinion of it? Should I download it or put it off for as long as possible?

It DOES use heaps of battery life and you can't close the apps (I used to do that to save battery power if it was running low)

Also, the format of practically everything is different

Personally, I don't like it

I tend to agree its interface is horrible it uses a lot of battery powwer and Apple must have realized it was not popular because up until sept 30th you were allowed to reverse back to the old IOS but has now put a stop to that so i assume that others do not like its features. Had i known i would have put it off too.

  • LifeProof Iphone case opinions please I really want to get a Lifeproof Iphone case, because they claim to be 100% waterproof, which is what I really want! But the warranty from what I understand will not replace your phone if the case doesn't work. I need to know if anyone has tried this case and if it works well, because I don't want to spend $80 on a phone case and have it not work, and break my phone.
  • Is is mandatory to back up your iPhone before downloading iOS7? Before downloading ios7 tomorrow, do I have to back up my iPhone 4S or do anything else? Is it mandatory?
  • IPhone vs Android. Opinions? I'm planning on getting a new phone soon, because my current phone (iPhone 4) is having some issues and my lock button is broken. I was just wondering what people's opinions are for iPhone v. Android? I've used iPhones and I'm used to that, but I've also heard really good things about Androids so I'm curious.
  • Iphone stuck downloading ios7? I downloaded ios7 on my ipad and it was fine. I have an iPhone 4. I'm downloading it from my computer. I checked iTunes and it said error and it couldn't download ios7. ITunes doesn't even show my phone connected to my computer anymore. My phone is now on the screen where it has the apple sign and the loading bar underneath it. It won't finish loading. I know I shouldn't unplug it but what should I do?
