UPDATE: 

It seems the issue has disappeared! I modified 3 i915 module options and after
3 days of testing including leaving the laptop on overnight i haven't
experience the problems again. Battery consumption has been great, around
2.5 watts when idle.

The module options modified were:

enable_guc_loading  = "1"
enable_guc_submission= "1"
disable_power_well  = "0"

for the guc module options make sure you have installed the latest firmware
from https://01.org/linuxgraphics/downloads/firmware. In your dmesg after
booting you will see these messages:

[    2.303462] Setting dangerous option enable_guc_loading - tainting kernel
[    2.303463] Setting dangerous option enable_guc_submission - tainting kernel
[    2.340111] [drm] GuC submission enabled (firmware i915/skl_guc_ver6_1.bin
[version 6.1])

These are the GRUB boot options used:

[    0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-4.12.4
root=UUID=d9310d7b-9422-463c-89ec-e1431caba3c4 ro nosplash quiet noiswmd
i915.enable_rc6=1 i915.enable_psr=1 i915.disable_power_well=0
i915.enable_guc_loading=1 i915.enable_guc_submission=1 i915.enable_fbc=1
pcie_aspm=force resume=/dev/nvme0n1p6

Again this has worked on a VAIO Z Flip 
model name      : Intel(R) Core(TM) i7-6567U CPU @ 3.30GHz

Kernel:

[root at localhost]# uname -a
Linux localhost.localdomain 4.12.4 #1 SMP Sat Aug 5 11:00:30 UYT 2017 x86_64
x86_64 x86_64 GNU/Linux

Please give it a try and let me know if it fixes your issues
