What's the best method when using Mophie Juice Pack™ Plus?

I just bought the Mophie Juice Pack™ Plus for my iPhone 4S and as I was reading the manual, it said the best way was to use the juice pack only when you need to charge your iPhone, but upon research and looking up forums, some people say it's best to use up the iPhone internal battery first then use the juice pack and others say it lasts longer if you use the juice pack battery up first then use the iPhone internal battery. Anyone know exactly what the correct answer is? Which method provides the best battery life or outcome? Or which method is more recommended?

Why am I so arrogant and how do I stop?

I brag a lot especially when I get new things.

My iPhone 4 broke yesterday and my parents said I'm getting the iPhone 5 so today I started bragging that I'm going to get a new phone. I was supposed to get it today but I'm going to get it tomorrow.

I feel like I have a big ego because I'm going to go to school tomorrow and everyone's gonna think that I have a new phone even though I don't.

I always tend to brag

I wouldn't feel bad if I could back up my own words

My IPhone 4S keeps freezing - 1

So I've had my 4s for over a year now. It recently started having this issue were it will work perfectly fine. And a couple of minutes later I will open it up by pressing the home or power button and the screen will be extremely dim to where you can barely see anything and the screen doesn't touch at all! It will do the slide to unlock glow thing 5 or 6 times then freezes in the middle and the screen shuts off from the top like someone scrolled the screen down to the bottom. It will stay off for a couple of minutes them eventually turn back on or I have to. Sometimes when ill just leave it alone it will do the same thing. Yes I've restored it twice. I've been closing all my apps I've deleted some apps as well so I have 4 gigs or storage left. I have had no liquid damage to the phone as I know of. Please help! It does this when it charges as well!
