This is my baseline system.. anything installed after this point will increase the Battery Drain and decrease CPU Performance. It also affects Heat related issues.

Google Account Manager and Google Backup Transport are big system resource wasters. Some people may run into problems later with a backup of contacts and general system backups of settings. My personal opinion is that I don't care about those enough to justify the data and battery drain being used my these 2 Apps. You may need to Defrost these later then Reboot and then do your backup/sync and then re-freeze.

I use a different MUSIC and EMAIL App and thats why I have frozen them. If you use them then do not freeze them.. its a personal thing for me.

DO NOT install XPOSED. It will most certainly cause an increase in CPU usage and will generate more heat. Its not supported by the CM system and not all the features even work properly. Its really quite harmfull but some users swear by it because of the extra features it enables. I like a clean, low resources used system. I will never use it.. but that is my personal opinion.. we all have an opinion and I respect yours.

STweaks is a great App that comes pre-installed. Use it to tweak whatever features you feel need to be changed slightly. Its a personal thing and I'm not going to tell you that you need to change this or change that.. thats for you to decide and play with. I personally dont feel the need to tweak anything.. the ROM/Kernel creators have done a great job for me already and I am beyond satisfied with the deafult settings for these.

Heat is caused by an increase in CPU usage which is cause by Apps.. the more Apps running in the background will certainly affect the CPU usage, use more memory, increase heat, and decrease battery life. Your screen being on increases heat and most definately decreases your battery life between charges. Keep a minimal system with only the Apps you need running in the background. Look into getting a TASK KILLER of some type. If you can kill the Apps that are still sitting in the background but not being used you will increase battery life and increase available system resources (RAM). Even your phone case can increase heat by trapping it and not allowing it to dissipate as quickly. I have a phone case, I feel its required to keep my phone safe, but I also know it affects the phone in a negitive way.. having a good case is the lesser of two evils (dropping phone vs heat trapping).
