Help with a 9780.

Hi, first of all, I'm from Ecuador. We have 3 carriers, Claro, Movistar and Alegro (CNT) (They also use 2G - 3G connections), here's my question. My phone its from Rogers. When I wanna install any hybrid, I use the .723 Pelephone base. I've tried Berrylicious, wu B@stard's hybrids, etc. (If you're going to ask the way I install the hybrids, I first do the factory reset, then wipe, and finally shrunk it with BBHtool) I don't know if I'm missing something, If I use my phone on 3G, I get high % of discharge (8 - 10%, when other people are having 2 - 4% of discharge using Aikido, Alcohol, Berrylicious Returns, etc) also sometimes getting high temperature (Using 3G, in 2G it works fine, normal temperature). Should I use another base? (From another carrier) Or what can I do?
