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 ;)
