Also, KonstaT is right. No battery drains. Use Battery Calibrator. Might help. Like, just last night when I was done using my phone for checking my Facebook and all, I shut off my Data and WiFi both. Phone was in call mode only. Battery
was at 70%. Now, when I got up in the morning, I did not face ANY loss. Battery was still at 70%.
Also, Idk if this is the right place to ask this or not, but my 8GB Class 4 SD card is very small now for me. So, can anyone suggest a very good 16GB card? It should be fast. Thats all. Budget, no issue.
