Hi guys..
Recently, while exploring my Xperia L, i stumbled upon the power management option in settings..
I selected the Stamina mode & i was really surprised with my increased battery backup..
My question : Can i always turn on this option for 24x7 ??? or should i use this option only when my battery is less than, say 60-50% ???
Will it harm the battery if this option is turned on for 24x7 ??
thanks. 
You can most certainly leave it on 24/7 however please be aware that this will impact a number of background applications such as notifications etc.

I´m having the same issue, turning my phone in to the stamina mode no longer makes a difference in terms of battery usasge.
Does anyone have advice on resolving this issue?
Looks like u have upgraded to 4.2.2 latest update.
No need to worry...This is a common bug we are facing with this update..!!
Hope the xperia developers resolve the problems soon...
