my only other tip would be to play around advanced power settings always with TS on the side while on battery and see if anything changes/triggers C9. for ex: Wireless Adapter Settings on battery / Intel Graphics Settings on battery etc.
I truly don't have the knowledge to answer your specific questions as just recently I've been trying to troubleshoot the battery life for professional reasons. I really need autonomy of +6h while working...
So i've had some free time to retry all my steps again and decided to do yet another clean install of windows. After that i enabled a reg key to disable driver updates within the Windows Update framework, did the usual uninstall bloatware, disable background apps and then run TS
-- Gotta love Windows -- its anywhere between 4-8 hours battery life estimates a few minutes apart
I guess up next is adjusting the power saving profiles within windows then maybe re-do the TS config settings -- but i dont see how im gonna get much better than 4-5 hours (be interesting to see if this stays or gets worse, presumably like it has before after a fresh install after a week or so) -- such a huge far cry from the 11 hours advertised and this is with he laptop just sitting idle, doing absolutely nothing -- im sure it will deteriorate pretty rapidly with light browsing
So I'm just gonna write this up because i'm sure in a year or two when i need to remember what i did to get decent battery life i'll be keen to know all the steps involved
6. After script is run head to your Power Options and set:
Hard Disk > AHCI Link Power Management - HIPM/DIPM > On battery > lowest
Hard Disk > Turn off hard disk after > On battery > 1 minute
Hard Disk > AHCI Link Power Management - Adaptive > On battery > 50 milliseconds
Wireless Adapter Settings > Power Saving Mode > On Battery > Maimum Power Savings Sleep > Allow system required policy > On Battery > No
Intel Graphics Settings > On Battery >Maxmimum Battery Life
Processor Power Management > Processor Duty Cycling > On Battery > Enabled
7. Install 'Intel Graphics Command Center' from Microsoft Store and run
Goto System > Power > On Battery and turn everything on for performance savings
8. Right click desktop and launch NVIDIA Control Panel
3D Settings > Manage 3D Settings > Preferred Graphics Processor > Integrated Graphics
9. Install Throttlestop
Settings for my Core i7-8750H (your settings will / may vary) -- triggered when going onto battery / off AC power
10. Start > Search for 'Battery Saver settings' > set the battery saver to turn on at anything below 100% 11. Settings (Modern UI) > Privacy > Background Apps (scroll to bottom left of list) > Turn off ability for apps to run in background
12. Start > msconfig > Services > Ticket 'Hide All Microsoft Services' > Check through services and see if you can disable any
Taken a screenshot of the battery life improvement -- It fluctuates between 5 hours - 7 1/2 hours of battery life varying completely on how hard it gets hit with browsing -- is very much good for 99% of my off power mains needs, this is with 10+ tabs open and using the laptop still -- Idle with nothing open sits around the 0.5 - 0.9w
I hope this helps anyone going through the battery life issues.
I finally had some time to read over the documentation on TS and I went and undervolted my laptop (though conservatively as opposed to examples for same CPU seen online).
On battery life I did get substantial gains: with low to medium use I can have solid 4/5h with the battery dropping from 95 to 20%.
So far it appears quite stable both on AC and battery.
