I used to have Windows 10 on my Lenovo Yoga 730-15" and recently I replaced it with Ubuntu 20.04 LTS.

I see huge fall in discharge time to around one hour. I tried installing powertop and enabling tlp but no luck. Is this some incompatibility with my laptop and Ubuntu? Or, is there any other way I could solve this?

Is your graphic card, Nvidia? If yes, it can help:

Go to Settings > Details , and see what 'Graphics' is your computer using. If it is Geforce, then open terminal and write

nvidia-settings

On opened window click 'PRIME Profiles' and select 'Intel (Power Saving Mode)'.

Restart your laptop.

    Hey thank you, That helped increase my charge time to two hours from one. It used to be around 3 hours before, can we do better.. ? – KayR May 20 '20 at 02:21
  • thanks this was what I needed, I went from ~3hrs to 8+hrs using this. Could you summarise what the main negatives of this approach? I assume a decrease in performance? – Matt Nov 27 '20 at 09:49
  • After this step, I was not able to open nvidia-settings again. 'sudo prime-select on-demand' and restart solved my issue. Note: 'watch -d -n 0.5 nvidia-smi' can be used to monitor GPU. – Atbey Feb 16 '21 at 00:30
  • The option is greyed out. :c Any idea how to make it available? – maciejwww Nov 07 '22 at 10:00
  • sudo prime-select intel will do the switch. The option is still greyed out though – Binh Apr 20 '23 at 19:50

You can try

  1. Laptop-mode-tools

  2. Linux-thermal-daemon

  3. TLP

Note: Different OS, different drivers, so we cant really do much here. I was using Windows10 which used to give 5-6 hours of battery life and now I am using Ubuntu 20.04 as primary OS which gives 2-3 hours of battery life max. Still try above things and see how much this helps.
