[Q] White lines on screen: battery error or more? topic

Hi there,

For several days bothers me a big problem on my Galaxy S3. At low battery levels, usually about 15%, but sometimes at 40% or even on 95%, come when I play games (edit: happened in Chrome and some other apps) white lines on the screen. The bars are significantly more after a few seconds and then denied me the network connection, so no Internet and no connection. When I play over Wi-Fi, it flickers more and more and my phone restarts. The only thing I can do is to charge, then it doesn't happen. My first guess was the battery, I will then also exchange times. Which reminds me two apps have invaded that there might possibly be with the blame: Tasker (edit: uninstalling didn't help) and Lucky Patcher. My question would be: Can be caused by these apps these problems? Is it just the battery? Or is there something else broken, so I have to replace my phone completely?

My phone: Samsung Galaxy S3 (GT-I9300) with CyanogenMod11, Xposed, Busybox.

I hope someone can help me!
