Poor battery life after last update

Hello! I got my Z3 in March and when I got it I loved its long battery life. I'm a very heavy user of my phone and managed to get 8 hours of screen on time out of it in between charges. I'm not sure if it has been gradual or sudden but I've noticed that lately, the battery life on my phone only lasts for about 3 hours of screen on time. I use my phone for the same things as I did when I first got it.

When I got my phone it was preinstalled with 4.4.4, I got the 5.0.2 update in mid-april and I got the 5.1.1 update a few days ago.

Here's some screenshots of my battery usage. http://m.imgur.com/JWe4Bt4,ybDx4wq

Also, I have quite a good knowledge of how android works and what can drain battery etc.
When I got 8 hours of screen on time when I first got it I was running google now and google fit (step tracker) and I stopped using those when my battery life started getting worse.

Please help! Thanks.
Jack

Post more screenshots of the whole list and also the graph, tap on the top 5 items on the list and post the time they were running.

Lets try this

 

charge the phone 100% > use it as you normally would > once the battery is downto 10% take the following screenshots

 

1 the whole list

2 tap on the top 5 items on the list

3 the graph 

 

or you can repair the phone with PCC

 

PC Companion (PCC)

 

 

Bridge (for Mac)

Z3 factory new battery drain.

I've got a new Z3 device a week ago as replacement. Day I got it upgraded to 5.1.1. I consider myself a good user and my older Z3 I had zero problems with. (except service's fault made it non water resistant that's why it's changed free of charge) it drains fast.
Usual drain is 300-400mA with no third party apps running and stamina on wifi off min brightness. It hardly ever makes 12 hours. I checked calibration. 100% is 4,35volts and 0% is 3,5. I tried cache wipe and safe mode. No wakelocks or other problems in graphs. I can show anyway. Goes like screen 25 chrome 22 hangouts 9 Facebook 6 android 5 percent. Anything climbs up easily in percents which means screen or os isn't really the leak. But I can't find why it leaks still. Can someone help?
