SOLVED Mint 19.1 and laptop battery life

Post by ejpaulich »

Thanks Moem. TLP made an amazing difference!
This is more of an informational question about mint battery usage. I'm a newbie. I recently bought an Acer E15 (e5-576-392h) specifically to install "dedicated" linux mint on it. It was a laptop that was recommended for linux compatibility. I pulled the Windows 10 hard disk out of it "completely" and installed a 500gb solid state drive. I also pulled out the memory chips and replaced them with 12gb of fast memory. Mint runs great on here. It is fast and snappy, no lag at all. The issue seems to be that it has become a batteryt hog. This laptop was rated at "12 hrs Long battery life". There is a sticker right above the screen that says that, and this is with windows 10 on it and a regular (non SSD) hard disk. It says it has a 6 cell battery and "long battery life" is one of its best features. With Mint, I barely am making 1/3 of that. My question, is this normal with Linux Mint? Does it by nature, use that much more juice than Win10? I have done nothing with the power management system. If this is normal for linux over windows, that is fine and I will just live with it, but if anyone knows something that could be responsible for such a battery usage difference, I would appreciate hearing about it. TY

Try whether this helps:
Update Manager - panel: View - Linux kernels
Install the latest kernel from the 4.18 series.
Then reboot.

If no avail, disable all visual effects in Cinnamon:

I recommend installing TLP. It's in the software manager and it makes a good difference.

TY Pjotr. I did as you suggested, changed the kernel to the latest 4.18 and rebooted. I will see if this makes a difference. I checked the visual effects slider and mine was set to off. Thanks again.

TY Moem I followed your recommendation and installed TLC. I will let you know if battery life improves. TLC sounds like it was what I was looking for. Thanks again.

I have a 4 year old ASUS laptop, and the battery life is roughly the same as it was with Windows 8.1, I just now unplugged the power cord, and held the mouse over the Battery icon.

it reports "10 hours remaining."

I know that I have forgotten to plug the cord back in after a remote session, and it beeped at me around 6 or 7 hours of continuous use....
surfing, downloading, etc...

I used Redshift to keep the colors in the 'red zone' and I also slide the power cursor on the battery to the lowest level I can, and still be able to see the display.

I do that for 2 reasons.
1) eyestrain
2) better battery life.

I am using 18.3 Cinnamon
Linux Mint 19.3 Cinnamon

He's right.
On windows 10 I get 2 hours (on a good day) at max.
On Linux I get 2hrs 15 minutes or 30 minutes more.

WITH TLP I GET NEARLY 5 HOURS BARE MINIMUM.

It sure does make a difference and TLP is often the first thing that I install whenever I come back to linux (and I come back as soon as I leave).
Writing doesn't earn me money, but it provides satisfaction that money can't provide.

sigh, I broke one of my cardinal rules in this thread.
Come back and report how it worked out.
TLP solved my problem.
