now I am using XA dual (F3112) for 4 months and cannot say its battery is somehow bad. Maybe better to say it is an average. 4G+wifi is always on, the same is for email, calendar sync, GPS, however I do not use gmail & hangouts & FB apps, some "useless" apps with high data usage have disabled background data. Most of the time the battery works for 36+ hours with 1-2 hours screen on daily. Some time after upgrade to 33.2.B.3.81 it was worser - but I have not discovered the reason. Just it was seen that system battery report does not count all usage - e.g. 80% discharged, but sum of % of all apps are <30% (8+5+4+2 and few more below 2% cannot give 100% !?)
Then I have installed the Accubattery app - and this gives some more real usage numbers instead of our guesses. And in developer mode I have disabled all background apps (they still work, but they are killed soon).
The battery "health" now shows 85% (capacity drops quite soon?), the counted battery usage varies from 1-2%/hour with display off (e.g. music player uses more) and 13-20%/hour with display on (where is the difference I do not know). This then gives the full battery times 5-7 hours with screen on and 40-70 hours with screen off - and for me (and my usage) this is not bad :-)
The maximum I have seen is standby more than 48h - but with low display usage.
Anyway it looks the recent Androids live their own lives, there is a lot of apps running in background, using battery and data and one cannot rely whether the battery will last one day or two :-(

Won't the nougat update be available by now? Another thing that dismays me is the screen durability compared to my former xperia L.. I accidentally dropped it on a soft wooden floor and it was slightly scratched but these are deep scratches that cant be removed. I always dropped my 2 year old xperia L and it hasnt shown a single scratch that is not removable. I can live with software issues (battery) but after my screen scratched easily this month, i'm convinced Sony just didn't decide to make this a good quality phone even compared to the reliable, sturdy xperia L.

THIS IS THE SOLUTION!
Settings -- wifi--- advanced--- keep wifi on runing sleep-- NEVER.
I just lost 4% in all night (9hrs in standby without Stamina modes)
You are right. It does save battery but switching off Wifi during sleep is not a long term solution. My profession demands constant checking of messages from email and whatsapp.

Oh man what the.... Happened today, my battery was at 6% so placed it down to charge, went to walk out for about 10 minutes, returned only to see the battery at 65%.
Amazed, unplugged the phone
Started working for my project, screen on for most of the time (though that almost Is very less) + 3G on
And then In FRONT OF MY EYES STARTED THE BATTERY COUNTDOWN 65..60..58....stable for 2 mins...47...38..suddenly.. 10..9..6..3 all this while I reached my 'adjacent' room (I hope you understand the SEVERITY of the situation) plugged it
.. .. 2%...1...0% literally it was charging but at zero %.
Out of curiosity I removed the charger aaaannnd black out..
First time I would say I have bought a USELESS DUMB DELICATE UNINSPIRING UNRELIABLE FRAUD (no promises kept) PHONE FROM SONY.
Sony never stick to its promises, IT KNOWS ONLY TO ADVERTISE IN STYLE BUT IN REALITY THEIR PHONES ARE AWFUL.
I REGRET (I may tell you I am a Sony fan still but due to other products)
