Why does my phone screen flash and not turn on sometimes?

I have a galaxy S5. Sometimes after I lock my screen and try to turn it back on the screen will flash and not come on. Other times it comes on right away. If my charge is low it takes forever to get the screen to turn fully on and be able to use my phone. Even at full battery it does this but when it's down to 20% or lower the screen itself starts flashing even when it's on. I'm wondering if it's my battery because the battery does have the red for water damage instead of white. Any help or suggestions would be greatly appreciated.
