Charging Problem

[afn]

hi every one.

i have a Xperia SP. i understand a unfamiliar behaviour for battery life!

if i charge it while it is On battery life is maximum 2 day.

but if i charge it while it is Off battery life is minimum 4 days for same use.

is this bahaviour normal?!

Do you charge your phone until 100%?Make sure it is fully charged by going into settings-about phone-status.You should get the message "full charged".
