Seems the same to me. Softer than 4.2 but same as 4.3

mine was worst during 4.4 update, .757 seems better but still cant beat 4.3

so far .757 not much problem tho, no camera shutter problem and hang during taking photos

Sometimes restart phone will stop  draining

Some apps can cause your phone to overheat. I remember once I installed an app, it caused my phone to overheat to 70C+. Even after restart, and dalvik wipe. After I uninstalled it it went back to normal temps, around 40C

fw 757 messed up ur phone?
A lot of ppl said that the battery consumption become better at 757 but why yours become worse?

agree on the battery thingy. same thing running on my phone but battery draining faster and heating up too.

Revert to Jellybean .681 like me.

I give up, 2 times I update 757, 3 times factory reset. My play store still can not update or install app. I don't know what's wrong. I've try clear data n cache on google play store, google play service, download manager. I also try fix n repair. My play store still not working. What should i do? Please need help.

before 757 everything is ok, only bug sound.
i hope sony release a new update again to fix

have u done a factory reset?

normally after an update, the phone will take a few days before the power consumption get back to an acceptable level.

On an unrelated note, when my phone prompt me for .757 OTA update and I couldn't update Via ota due to root, it drains my battery quite fast too. restart my phone, then it doesnt drain anymore. I notice this happening on previous OTA prompt update as well, if I didn't update or restart, my battery will drain.

just try restarting your phone. no harm trying. cheers

not really bro, i just got my phone 2 weeks ago and realized the best was during JB...after it went to kit kat it was horrible.. when i forced downgrade to JB, the phone became unstable..suddenly auto restart..suddenly sleep of death... forced me to go up to kitkat again..sigh

yeah... i also don't quite understand why...

in fact with 757, i find it to be better than JB... volume got louder, ram usage less, camera quick launch working, battery so far i think better than JB

for those who face problem, these are my suggestion:
1. if only certain apps having problem, try uninstall and re-install the apps. if still cannot, try contacting the apps developer. like wechat, i think alot of user complain about it. so i think most probably is the apps itself not really compatible with Sony's kk.
2. if whole phone behaving weird, try do a factory reset. with this, try not to backup too many of your apps, only those essential ones and those that you need to backup the data only. if there are some problem with the apps, chances are when u restore back those apps, it will still be causing the same problem to your phone. do a factory reset and redownload those apps that you need.
3. if factory reset can't do, use the repair function in PC companion
4. If still having same problem, i suggest u to download the firmware and flash it via flashtool manually
5. if still cannot, can try other country's firmware or just downgrade back to JB (but recently 1 user face even more problem after downgrade to JB, dunno why)

well, these are just my suggestion. good luck!

i don't think we can tell much from those screenshot regarding battery drain

in the past i use wakelock detector to see if there's any apps keep running and awaking my phone. but due to kitkat restriction, the apps no longer working 

maybe u can use other apps to monitor like betterbatterystat (if i remember correctly). i myself have not use it b4 la

try removing batterbot pro

i never liked all these battery management apps. not proven and only takes up resources to serve you ads

celcom, the problem starts after i update to .757

I upgraded to KitKat, didn't like it, then downgraded to Jellybean with no problems. Why don't you try that? Maybe you are lucky too.
