Re:X1 Extreme Gen2 Battery life

2020-05-05, 16:40 PM
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...

Re:X1 Extreme Gen2 Battery life

2020-05-06, 11:57 AM

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

Re:X1 Extreme Gen2 Battery life

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

 

X1E Gen 2 - i7-9750H / 32gb ram / UHD 4k display

 

  1. Install a new copy of Win10
  2. Before completing the OOBE on the new install follow the below steps using the below script:
    Script: https://community.spiceworks.com/scripts/show/4378-windows-10-decrapifier-18xx-19xx
    Process: https://community.spiceworks.com/how_to/148624-how-to-clean-up-a-single-windows-10-machine-image-using-decrapifier
    (OOBE > CTRL + SHIFT + F3 > Audit Mode > Run Script > Reboot (as described in the 2nd link))

 

3. After reboot continue with normal setup of user account

4. Install all updates / Windows Updates / Microsoft Store / Lenovo System Update

5. Download Github script to enable all power saving options

     Script https://gist.github.com/Nt-gm79sp/1f8ea2c2869b988e88b4fbc183731693

 

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.

that's quite comprehensive; thanks for the thorough post.

albeit potentially less systematic than you I ended up doing the same things with similar results.

would just add that in my case upgrading the AHCI controllers appeared to be quite important (though my hardware's different).

just a quick follow up...

 

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.

On Idle it's anywhere between 0.5 and 0.7w.
