Are you a digital nomad?

Yes, I am. I always work in cafe or coworking space in Makati. So the battery life of my laptop is always mattered. As I used my new Macbook for several months, the battery life of it eventually became shorter.

I tried some common techniques such as killing unnecessary startup applications. But I couldn’t be satisfied with it. Because some processes and daemons were always consuming CPU usage like 0.2% each. Especially, Core Sync and Adobe desktop service by Adobe Creative Cloud were the top battery drainage.

So that I tried reseting kernel panic and some controller information. And then, although I didn’t have much confidence, it solved the problem on my Macbook.

Here are the steps how.

Resetting NVRAM

1. Shut down your Mac.
2. Locate the following keys on the keyboard: Command (⌘), Option, P, and R.
3. Turn on your Mac.
4. Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.
5. Hold these keys until the computer restarts and you hear the startup sound for a second time.
6. Release the keys.
