Regarding the battery life, for the spec that you require you will struggle to find any notebook that has an exceptionally long battery life and there is a very good reason for this, gaming notebooks that have a discrete GPU must have the Windows Power Plan set to High Performance or the discrete GPU does not get the power that it needs to be able to function and the notebook as a consequence will revert back to using the on die video from the CPU.
In addition to the above, because of the previously explained power demand, it is not practical to use gaming spec notebooks when they are not being powered directly from the wall socket, the GPU power demand sucks the life out a battery in no time.
