Looking for the most energy-efficient Linux release? Find ways to maximize battery life by running at a minimum speed.
Hey everyone, I own the Acer Swift 3 laptop that advertises a 10-hour battery life. That claim holds up, it really does last around ten hours. However, a year ago I noticed the CPU throttles to about 70°C and the GPU to 65°C, which causes significant performance drops during games. Using Throttlestop and ASUS GPU Tweak 2, I set both limits to 90°C, and gaming performance has improved noticeably. The downside is that even without gaming, the battery only lasts around two hours. When I switch to dark mode and battery saver, it gets worse, especially during power outages. I'm trying to find ways to extend battery life further. The manufacturer says only a 10% capacity loss is expected, so maybe with some tweaks I can stretch it to 7-8 hours. I'm considering a dual-boot setup with a Linux distribution, which would let me browse the web or access documents without affecting battery life much. The Linux OS might be more efficient. I've tried following Linus's battery-saving advice, but it hasn't helped much. It seems software usage is affecting the battery. Even after restarting, my battery still only lasts about 2.5 hours.
My personal observation is that power handling in Linux tends to be less efficient than in Windows. Using Powertop doesn’t instantly extend your battery life, but you might save a few extra minutes by limiting CPU speed below its specifications. Your Linux experience can feel more stable on battery, though it won’t be four times better than Windows. Laptop performance reviews often don’t reflect real-world use, except for the M1 MBA, which performed as advertised, while most other models fell short significantly.
I own a Lenovo Ideapad L340-15IRH. On Windows it lasts roughly two hours, while on Manjaro under Linux it runs three to four hours. Manjaro can be quite heavy sometimes, so I’d suggest going with KDE desktops—they’re lighter and packed with features. Pick a distro that’s not overly bloated, since extra bloat reduces battery life. Doing both of these should keep your battery above four hours.
