Load capacity as at the beginning

I started to have abnormalities, such display that flickers and the phone that goes out and that even at 60% load. Relighting all apps in operation before the extinction trying to restart, I had no time to stop the wi-fi or gmail sync Note that died out again. Therefore impossible to use without hand it to load.

Since the new battery this anomaly has disappeared. I find again the 2 days of use without charge, being careful not to use the wi-fi connection or data if necessary. If I forget the Wi-Fi turned on, charging is required within 24 hours.
