Hello guys. I am using iphone 4s from last 5 years and I realized that in this phone all of the its features are very well very good but one this of this mobile phone is disappointing me that is its bettery back up. its a 3g phone and it also support high defination games I am a big fan of racing games or fighting games but all the maximum games are high defination games and I only maximum to maximum 15 to 20 minutes play the game and after that my bettery is comes at 0% from 100% . Over all it is a very good mobile phone only its bettery is not good and those people who like to play high defination games like me than I suggest that plz donot buy this phone it is not made for you.
