Reddit user /u/alccode recently stumbled upon something that could vastly improve your experience with your laptop. In this post, they report on checking the CPU usage of the desktop and metro versions of OneNote side by side running on a Surface Pro 3, discovering that, while the desktop version was using over 20% of the CPU, metro OneNote was only taking about 1%. On top of this, it turns out that the desktop version of OneNote drains up to 10% battery writing the same amount of notes for the same amount of time as the metro app, which only consumes about 1-2% battery life. For programs that perform the same core function, this difference in resource consumption is a big deal.
People like to complain about how the metro app is lacking in features, and they’re right – but it seems like that’s by design. Many of us just need OneNote to scribble down a few notes every once in a while, and it turns out that the metro version of OneNote allows us to do just that without consuming nearly as many resources as its more feature-rich desktop counterpart. It’s a fair knee-jerk reaction to lambaste any program that strips features away from its other versions, but with this difference in CPU/battery consumption, it’s arguably worth it.
For those with more powerful machines, this difference in battery efficiency may prove negligible (The reddit user /u/hungs reports seeing no significant battery drain on their laptop, which sports an i7 processor and 8gb ram.) That being said, many people are using significantly less powerful computers, and it’s important for them to make every bit of battery life count. With this difference in battery usage in mind, it may prove to be the case that the metro version of OneNote could, for some users, become the application of choice over its desktop counterpart.
