Why does my iPhone 6 die so quickly now?

I dropped my phone and broke it and had to switch to my old iPhone 5c, which had a horrible battery life. I finally got my iPhone 6 fixed, but now my battery dies so much quicker then before. I'm on battery saving mode, I have bluetooth off and my screen brightness is usually down almost all the way. I do listen to music while i'm in school but that has never been a big problem before and all my apps are closed. What's the problem?

How to access my old photos that used to be automatically synced onto my computer on iCloud?

Does anyone know how I can get back my old photos like my Mac used to?

Is this too much to ask for?

By the way, that not's supposed to be like harsh/sarcastic, it's a real question.
Well, Christmas is coming up fast (Happy Holidays to everyone!) and my parents asked me to make my Christmas wish list today! I asked if I was good this year and my mom and dad said I was pretty good. I'm an AB student, I do all my chores-but I do sometimes get into arguments with my mother. (I get short tempered at times, but i'm working on it!)
Here's what I'm asking for:
A Vera Bradley Wristlet (37 dollars)
Book series (20 dollars)
And the big thing…
an iPhone 6! (along with the case, which is 10 dollars, and this screen protector thing, which is 7 dollars.)
I haven't given my parents my list yet.
I don't want to make them think I'm a brat because I'm truly not. Do you think it's too much? Thanks for anyone who helps, and once again, happy holidays!
