by installing wp 8.1 my battery life was too short ... after full charge it tells me 14 hours left
but I made hard reset and charge the battery to 100% I check battery sense it tells me 2 days and 1 hour
cortana , facebook , viber , whatsapp , weather , sport ... all of them work in back ground
battery saver is on , brightness automatic
the phone become more fast and stable
