iphone 4s-new-battery drain and app crashing

Hi I have recently bought a new iphone 4s- 16gb. Updated it to 5.1.1 version.The iphone has major battery issues. I charged one night and morning it was drained. It was only on wifi.Also, while on wifi - the battery  drain is too much. The standby time and the usage time are generally same.- Location was off-Bluetooth off- wifi on- Emails on The drain is very fast.  Next - the apps like facebook, contacts, watsapp etc carshes quite frequently.I installed an app called 'Battery Doctor', in the stats i found that the CPU usage is very high even wiht only 1 app running.similar is the case for RAM usage. Would require help from someone to help me. I have even tried Restore but the conditions still exist. Regards
