I need more Power!!!!

I currently find myself dying, no no that's not what I mean my Battery in my iPhone and iPad dying a lot faster. Which sucks big time because those are my main gadgets, I'm writing this on my IPad mini with 53% battery Juice. My demands for the ipad are becoming more in terms with the battery, it seems every time I update the OS the battery holds less juice and last a shorter period. Now you may not see or realize it but I am a major user and notice small things, and the battery is lasting a lesser time with each update. I hope the next Gen iPad/iPhone battery will have a electrifying affect no pun intended.
