So I purchased a refurbished MacBook pro 15 inch 256gb SSD iris pro base for 2k Canadian. I can get an upgraded model for around 400 more used with AMD graphics and 512 SSD.

I wanted to know if the battery life is the same on both these models, will the amd kick in at random times and reduce battery life? I know it kicks in for really intensive apps but I am not sure where the line is.

Also is this upgrade really worth it? My current Mac has a bit of UI lag, but I don't assume the amd variant will improve things as the amd card won't kick in for basic navigation around the OS.
