[5.0.2] [Lag/Heat/Battery - Problems] Need advise on how to get ZL smooth again



Hello together first my specs:

Model: Sony Xperia ZL C6503
Android 5.0.2
Build: 10.6.A.0.454
Kernel: 3.4.0-perf-g8fa3dae BuildUser@BuildHost #1 <- Vanilla Kernel I beliefe
Root: Yes with kingroot following this HowTo Link I now got SUperSU 2.46 installed
Bootloader: Locked - I didnt unlock it and I think the rooting didnt unlock it either
Apps: ~95

I have the following problems:

1. Ever since 4.4.4 my Sony ZL is somewhat laggy. With 4.4.2 I had a really smooth experience but since 4.4.4 its been a dirt road. I am happy that Sony still brings us the newest updates with Andorid 5.0.2 and soon 5.1 but I hate that my user experience drasticly decreased. Not only do games lag since Lolipop, now the UI interface is lagy and my browsers (Dolphin with Jetpack) lags. Its just a big **** up! Its not smooth anymore and it doesnt make fun to wait several seconds (3-5) before apps open or close. I have no longer any task killer, with my last it felt to decrase performance instead of increase.

2. I have a heat issue with the phone somtime it gets really hot really fast.

3. Battery doesn't hold a whole day anymore. Could be casue the phone is 2 years old already but sometimes I have really bad battery life. If I turn on GPS I can forget to use my phone cause battery dies within 3 hours and apps just collapse under the heat.
I have Stammina tunred on and @30% Low Battery kicks in. @15% Battery saver tunrs on.
Battery drops from 12% -> 0% and turns off phone. Sometimes I get to 8% and then 0%

I would like to fix those issues and I need your help and advise. Yesterday I was almost to the point where I threw my ZL out of the window but I decided to give it a last chance with some help of the XDA community. So for my phone you are the last chance otherwise I will throw it out.
My Problem: I dont really want to completly start fresh and install all apps and configure everything again. I have Titanium Backup insallted (but I dont really know how to use it). If I have to completly start fresh I will probably get a new device casue there I will have to do the same legwork anyway. Only if money is thight next month I will stay with the ZL and do it all over again.

So can you guys help me to fix my problems? My biggest problem is the lag issue. I can life with the allright battery life and the heat issue but the lag drives me insane.

Edit:
In the past I already tried to root my phone while I had 4.4.4 but at the time there was no root available yet and some tasks failed. Not sure if that had any impact.
