My Z10 need some help

I see a lot of complaints some seem like they are valid some seem just plain ridiculous..
I don't mind sideloading apps because I knew what I was getting into when I bought a blackberry.
I have no problems in a car, rebooting, freezing, nothing of that sort..

I just feel like my battery life is very horrible and I am not sure if theres anyway to fix it..
Any help is appreciated.
I have had my Z10 for about 2 weeks now
