IPhone 6 dies extremely fast? - 1

When I first got my iPhone 6 at Christmas 2014, the battery was great. It would last for two days. Now, it dies extremely fast even when not in use and on iOS 9. It was doing it before iOS 9 too. I have location services off, background app refresh off, my mail is set to fetch manually, and everything else that could be draining the battery, but it still drains really fast. What do I do?

What stereo receiver should I get if I own two 8 ohm speakers?

I own two 8 ohm speakers that both say 200W on them. I would assume I would need a stereo receiver that has the same impedance and gives 100W per channel. At the same time, those kinds of receivers seem to be on the more expensive side (I checked out the ones sold by Yamaha) and I would like to be able to use my iPhone 6 through the means of a dual aux cable or Bluetooth, yet I'm having difficulty finding one.

So my questions are: what are the minimum specs for a stereo receiver I can get away with, what are the optimal specs I can get away with, and what is a reasonably priced stereo receiver currently on the market that can support an iphone 6?

What color iPhone do you prefer? - 1

I see that most people have the space gray versions. I don't really care about the color so IIm thinking about going with whatever seems more popular.

If I'm getting the iPhone 6s for Christmas, should I preorder it and when? - 1

My upgrade is December 21stbwig AT&T. It's going to be around Christmas so should I be safe and pre order the phone? Can you pre order months ahead? If I do will my upgrade still go into effect? Also when you get an upgrade do you trade in your old phone? And do you get the upgrade the day your old contract expires? What's the period of time to upgrade after that date?

I dropped my iphone 5s in the toilet? - 2

Hi, i just dropped my iphone 5s in the topilet, i was playing music before i dropped it, after i dropped it the sound got significantly quieter. Also, when i pulled it out, the top 2 inches or so of the screen had pink vertical bars. I immediately turned it off, shook off as much water as i could, and i now have if in front of a fan drying.
Is there anything else I should do, and when should I try to turn it on again?
