XV6800 Tweaks? NEED HELP!
 

I recently got the Verizon XV6800...I'm kind of new with Windows designed phones, even though I had a Moto Q and Blackberry. I'm curious, sometimes when I slide my phone to text, the screen takes a few extra seconds to load. I downloaded a so called cab file that was to improve battery power and performance but I can't seem to tell much different. can someone PLEASE direct me to how I can improve my performance of my phone, as well as maybe the battery? THANK YOU!!!!
