have you excluded apps and/or services?
You can exclude apps in stamina mode only to remain active not to deactive em,it says it clearly you can add apps or services you want to remain active while stamina mode is enabled.
pesky_89 try thIs send an email to your self while you have stamina mode enabled or tell a friend to send you a message to your facebook account,and of course have your phone at locked mode,if the phone beeps with your email notification or facebook message then stamina its not working for you,if not this means that wi-fi disables and stamina its working just fine.
I have got a similar problem, with stamina mode on, my phone battery drops as opposed to the situation before the 4.3 update. This morning i realised that i dropped 15% within 5hrs when i was asleep, in 4.1,2 it wouldn't do so. The stamina mode is in default mode, i.e i have not excluded any app to remain active when the screen is off. I'm using Xperia T LT30a which i updated on 15th feb.
stamina mode it is working while the wi-fi data icon remains there,the battery usage its not dropping so fast while its enabled,now if i disable stamina battery drops more faster than in normal mode..4.1.2 was a different story but i dont think 4.3 stamina its bugged.
my phone discharged 6-8% over the night !!!! and wifi process was on 5h 30min out of 7-8h, while stamina was on.
this is fuking useless.
I take it you have gone into settings, wifi, advanced and changed 'keep wifi on during sleep' to never?
