[5.0.2] [Lag/Heat/Battery - Problems] How to fix those Problems?

[z1ckZack]

Hello together I have startet this Thread in the ZL Forum as well but there are way more Z Users than ZL So maybe you guys can help me too? first my specs:

Model: Sony Xperia ZL C6503
Android 5.0.2
Build: 10.6.A.0.454
Kernel: 3.4.0-perf-g8fa3dae [email protected] #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.

I have the same problems(except lag) on my XZ1 it happend after I sent it to sony center because I bricked it, they replaced the motherboard and battery but the device gets really hot really fast (10 min of browsing and the device is 70°C) idle temps are 50°C and the max time my battery lasts decreases every day, my phone is on for 2 hours with mininal use and it's down to 69% i'm sending it to sony next week as it is a 3 month old device

You could try to change the gouvenor of your CPU. I use interactive. It saves battery and the phone doesn't heats up so much (its still really hot sometimes). You Phone also becomes more efficient, because it only clocks fast if you need the power. You can do that with the PACPerformance Application or Antutu CPU Master as example.

If the interactive gouvenor doesn't helps, you can still try performance, this will give more power to your applications, but degreases battery life.

The heat comes from the old Snapdragon S4 Pro Processor that needs to clock most times at the maximum clock speed and it has no real thermal throttling. One time my Phone was at 100°C. Then the Android Operating System started to shut down the phone. The screen also started flickering.

After you got the 5.0.2 Update your Phone should feel much smoother.
