Bettery Draining so fast even in stamina mode (.205)

[axiom1]

Hello, i updated my XSP 201 to 205. after that, bettery draning so fast! even in stamina mode. took 47 min to take down 92% from 100% charge.

here is proof

bettery flow :

look, screen wasnt on. 

proof of stamina mode on

last night i update my phone. then at 6 am i was in bed and woke up like 10 am. And saw my phone switch off itself due to zero percent charge issue. it was like 4/5 hours to take down 23% to 0 %. stamina mode was always on, data connection was off. this isn't normal, right? look at the battery drain on picture. any valid reason behind that?

Battery getting dry very soon after.205 update. Got fed up with this problem. Feeling very bad for these type of updates from Sony.:-(:-(:@
Worse experience

205 are good for me, everything runs faster but becarefull with your applications because 205 utilize more rapid processors clock rate and 205 memory management have more tendency to close application to save memory. On some scenarios it has a loop between closing applications(by system) and applications restarting(by application ).

its the cause of wakelock problem

Well, i have this problem since we get Android 4.3 update. I search in every forum in the world, but nothing. The only thing i know is that this battery drain is related to the WCDMA Radio. It's mean the energy needed to maintain the connection with the cell towers. The problem is only in 3G (WCDMA) network, that's why in the "GSM only" mode, everything works fine. The probem has nothing to do with the data traffic (internet conecction), that's why STAMINA MODE doesn't help to stop the draining. 

The best way to determine if you have this problem is to leave the phone charged to 100% before bed, no wi fi, no data traffic. When you wake up in the morning (8hr aprox) should be still in 100% -99%. But if you have this problem, will be at 82% -80% or even less.

That's all I know about this. I recommend Intelli3G along with xposed framework, to automatically change to a 2G network when the screen is turned off or you are on Wifi.

And I'll keep hoping Sony fixes this problem

PS: sorry my bad english

If you have problem with battery drain with no wakelocks ,try this :

turn off stamina with the switch. go to settings/app/all/eco mode controller ,stop it and clear DATA.

after this HARD RESET the phone.(little yellow button under the back cover) turn on the phone and stamina.

and lets see what happens...

i hope it helps a bit.

Indeed 3g mode have more complicated processing than 2g mode and usually 3g band uses higher frequency it cost more energy to do.
