Visualize mac's battey usage and battery health using different charts. Battery levels, consumption rates, maximum capcity, level distribution... All presented to you on different time scales so you can know your mac better.
Hi everyone, I made this app to record mac's battery data and visualize it with chats.
I made it because I was kinda paranoid about my mac's battery life and battery health when I bought it last summer. Apple said it could last 15 hours but I didn't believe them. And the battery health dropped a bit fast.
So I wrote a script to record my battery data and made this app to present the data. It calculates consumption rate so I can easily know the battery life. For example, if it is 12.5 %/hr, then the full battery can last 8 hours at this rate.
It also shows your battery health data like how the maximum capacity and cycle counts have changed over time. I heard of the 20-80 rule which is keeping your battery levels between 20% - 80% could improve battery health, so there is also a chart to show your battery level distribution.
The data is presented on different time scales. You can see detailed information of last 7 days, or daily average data of last moonth, or monthly average data and health data of all time.
There is a disadvantage though which is that the user have to add the contab tasks themselves. Because it uses crontab tasks to record the battery data periodically, and third party apps are not allowed to edit crontab tasks. I try to make it as easy as possible. All you have to do is to copy a command and run it in terminal. And the scrips are open sourced on Github so it is safe (the app is also completely offline). But still, it is a little inconvenient.
This is all I want to share. If you also want to try it, there is a free lite version in App Store `PowerCharts - Lite`. Thanks ;)
Being able to see detailed charts of my Mac’s battery usage and health would be super helpful. Tracking things like consumption rates and capacity over time would make it so much easier to manage battery life and know when it's time for a replacement
awesome product, @tedlex.
love the data visualization aspect.
can't wait to see how my mac battery performs.
This is a very useful app for anyone who wants to keep a close eye on the health of their Mac's battery. The detailed graphs showing consumption rates and battery power distribution are very helpful in understanding how battery usage time varies. It's also great that the app is completely offline and transparent through open source scripting. Although a small amount of crontab setup is required, this is a solid tool for anyone who cares about battery performance! @tedlex
That's a fantastic idea! Visualising my battery's health and usage through different charts would certainly give us a deeper insight into how I perform over time.
Here’s how I imagine it: A line graph showing daily, weekly, or monthly trends could help us understand how my battery levels fluctuate under different usage patterns.
I love it when users out there create productivity apps and tools generally for Mac users for a better UX. Massive respect, especially when Apple torments you with it's tedious processes to publish an app on its platforms 👏👏👏
That’s a really neat and practical app idea! It’s awesome that you took your own concerns about battery life and health and turned it into a useful tool for others who share the same worries. The fact that you’re making the data visual and accessible with easy-to-understand charts is a huge plus, and the 20-80 battery rule feature is a great touch for people wanting to optimize battery health.
I understand the challenge with having to use crontab tasks—while it might be a bit inconvenient, it’s reassuring that you’ve made it as straightforward as possible, and open-sourcing the scripts definitely adds to the trust factor. Having a completely offline app with privacy in mind is also a great approach, especially these days when people are more conscious about their data.
Good luck with PowerCharts, and thanks for sharing it! I’m sure Mac users, especially those like you who are mindful about battery performance, will appreciate the insights it provides.
Nice app, love the concept,
I'm also building a cool directory of Mac apps. You should add it there.

Congrats on the launch! 🎉 This app sounds like a fantastic tool for Mac users who want to keep a close eye on their battery usage and health. The detailed charts and various time scales for data visualization are great features that make it easier to understand battery performance over time. Even though adding crontab tasks manually might be a bit inconvenient, the benefits of having such in-depth insights definitely outweigh that minor drawback. Kudos for making the app open-source and offline for added security. Can't wait to give the lite version a try. Awesome work! 🚀🔋
This is the Mac battery data visualization this is useful, let try this new, congratulations on the launch.
This is such a cool idea, Ted! As someone who's always curious about my Mac's battery performance, PowerCharts seems like a dream come true. Have you thought about adding a feature that compares your battery stats with anonymized data from other users? It could be interesting to see how our Macs stack up against others of the same model. Great job on addressing a real need!
Well done on the release! Visualizing battery usage with detailed charts is such a useful feature.
Hey Ted,
Does PowerCharts provide any recommendations or insights based on the data it collects? For example, does it suggest optimal charging habits or flag potential battery issues?
Congrats on the launch!
I rather do not want to test it because I would be shocked about my Mac usage. These weeks are crazy and not so sure how long it will last. New Mac is on the way soon :D Good luck with the launch! :)
