Anker’s New Battery Pack Is One of the First With USB-C Power Delivery

Ever since laptops and game consoles started launching with USB-C charging, the promise to effectively infinite battery life with the help of USB battery packs has been tantalizingly close, and yet so far away.

While just about any battery pack can trickle charge an Apple MacBook or a Nintendo Switch while they aren’t in use, very few include the USB-C Power Delivery standard that enables full speed charging. But Anker’s looking to change that with the new PowerCore+ 26800, the latest iteration of your favorite line of USB battery packs.

This massive battery pack’s USB-C port can output up to 30W at four different…

How to Maximize Your Linux Laptop’s Battery Life

Laptop manufacturers spend a lot of time tuning their device drivers for Windows battery life. Linux usually doesn’t get the same attention. Linux may perform just as well as Windows on the same hardware, but it won’t necessarily have as much battery life.

Linux’s battery usage has improved dramatically over the years. The Linux kernel has gotten better, and Linux distributions automatically adjust many settings when you’re using a laptop. But you can still do some things to improve your battery life.

Basic Battery-Saving Tips

Before you do anything too complex, adjust the same settings you would on a Windows laptop or MacBook to maximize battery life.

For example, tell your Linux laptop to suspend—this is what Linux calls sleep mode—more quickly when you’re not using it. You’ll find this option in your Linux desktop’s settings. For example, head to System Settings > Power on an Ubuntu desktop.

Screen brightness can affect battery life dramatically. The brighter your display backlight, the worse your battery life will be. If your laptop has hotkeys to change screen brightness, try them—they’ll hopefully work on Linux, too. If not, you’ll find this option somewhere in your Linux desktop’s settings. It’s available at System Settings > Brightness & Lock on Ubuntu.

You can also tell your Linux desktop to turn off the screen more quickly when it’s inactive. The laptop will use less power when its screen is off. Don’t use a screensaver, as those just waste power by making your computer do more work and leaving the display on.

You can also disable hardware radios you don’t use. For example, if you don’t use Bluetooth, you can disable it to gain some more battery life. Head to System Settings > Bluetooth to disable Bluetooth on an Ubuntu desktop.

If you’re not using Wi-Fi, you can save a bit of power by disabling that, too. On Ubuntu, head to System Settings > Network and enable “Airplane Mode” to disable Wi-Fi and other wireless radios.

Remember that what you do with the laptop is also important. Running heavier software and using more CPU resources will cause your laptop to use more battery power. For this reason, you may want to look at a more lightweight desktop environment, such as the Lxde-based Lubuntu instead of the Unity-based main Ubuntu desktop.

Install Proprietary Graphics Drivers (If You Need Them)

If your laptop has integrated Intel graphics, congratulations. You shouldn’t need to worry about power management issues with your graphics drivers. Intel graphics aren’t the fastest, but they have excellent open-source driver support and “just work” out of the box.

If your laptop has NVIDIA or AMD graphics, however, you may need to do some work to decrease power consumption.

The worst case scenario is a laptop with NVIDIA Optimus or AMD’s switchable graphics. Such laptops have two different GPUs. For example, an NVIDIA Optimus laptop will have both a more powerful, battery-draining NVIDIA GPU and a less powerful, battery-friendly Intel GPU. On…
