Why does my iPhone 5 feel heavier now?

When I first got my iPhone 5, it felt incredibly light. Now that I've had it for about 5 months, it feels heavier. It's not because I've gotten used to it because I've compared it to a iPhone 4, and it *almost* feels the same. I can't help but think it has something to do with the battery. Anyone have any idea why?

Because when you got it you used to compare it to your old cell, and therefore feel it very light now you are used to it and probably you were tired so you feel it heavier practically it can't get heavier think about it your data is not a solid thing. And maybe you have added the cover case or something

The battery may expand after aging 5+ years but it will not get heaver.
