Come on bro why u blaim all g pro phone may b ur friend have faulty phone or having any battery issue or any crapy rom i had used this phone around 8 months and seriously it is the only one phone which i used so long just due to its performance and again i am willing to buy it again with full acrz my phone battery lost at heavy usage one complete day in my opinion it is the best price to performance phone yetG pro has poor battery life. I have experienced it myself. I used the phone on wifi for 10 minutes and its battery fell down 10%. The guy who i bought it for sold it after a few days because of the poor battery life. And its because of Snapdragon 600 being not as power efficient as S4 pro or Snapdragon 800.
