Hello,
After a small marginal KitKat (4.4.2) update with build number 19.1.C.0.116, my Xperia T2 Ultra Dual's battery is draining heavilly. I went to Power Management & found it's the screen itself that's consuming 40% of it. It's such an application that I can not disable or stop. What should I do? Please help.... 
yeah, I wish someone from internal could give explanation man.
it's called "Support" forum after all
not being disrespect.
but we aren't randomly posting, we all aware of how this thing should work 
Really 3-4 days ?
man I regret updating it after buying it 
that's crazy time for 3-4 days
hope the next fix will fix this too
It'll be awesome
also longer life time extend battery life by descrasing charging amount done
big hope in next update
I guess you are new to Android.
The "Screen" app in the listing refers to your actual LCD. It is normal because LCD does consume a lot of power and it is correct that it is shown to use up to 40% of the battery. And if you set the brightness to "auto" and use your phone in outdoor environment, the LCD would blast full brightness to give you more visibility in the outdoor environment. And it would use lower brightness when using it in indoor environment. We have to be realistic to the % "screen" is using. We should look at Screen On Time ( the Time On in the information of "screen"). We refer this to SOT.
When I was with Jelly Bean, the SOT usually give me 6+ hours. Which means that the screen is on for 6 hours plus before the battery depletes. With Kitkat, I lose about an hour and ended up with 5+ hours. It is not too bad as I am quite a heavy user and I charge the phone every night.
After root, I use apps like Greenify and now the SOT returns to 6+ hours.
Just sharing my experinece here. I would suggest forumers to do some reading on how Android works in order to understand and get the most out of it.
