It's unlikely it'll get as good as Samsung or Apple by that time but it should definitely improve. Unless they made some critical mistake in the hardware, they can make continuous improvements in the software.
It's no surprise that this is one of the last things they're focusing on. Idle power management on modern operating systems is hard and is very kernel and hardware specific because kernel interrupt and process scheduling comes into play. Hence why Apple is so good at battery life - they have such unilateral control over the hardware and software stack that they can make optimizations that Linux/Windows/Android really struggle with.
