Hi,
Based on what you are saying I can only recommend a new battery, since Android Jelly Bean (4.1.2) is battery draining, but clearly not as much as yours.When my phone is on standby (idle), and I wake about 8 hours later, it still has only lost up to 10%. However, I have a Xperia S so it should be a bit different...
I hope I helped.
If you have any question on changing battery on Xperia ion, feel free to ask.

Hi,
-you could enable stamina mode, it should be in power managment.
-You could flash back Android ICS 4.04 or GB 2.3 and see if it helps...
-When phone reaches 50% in battery level turn it off and pick out the battery (IF YOU MANAGE TO DO THIS) for a few minutes. Put it back and connect the charger, now charge the phone turned off for about 5 hours or overnight. Start the phone as normal and check if the battery life time has improved.

If I helped, press thanks

yipeee i think my problem is sloved
i tried instaling ics again and no improvement in battery,then i change it back to JB and root it.then i installed CWM and cleaned my dalvik cache,now my battery is awesm, for 7 hours of sleep it only drains 6%,no battery saver used,just extend battery life under battery settings. i think cleaning cache resolved my problem
