Capacity Info: Battery Health - Battery capacity & status

Are you curious about the remaining battery percentage of your smartphone or tablet, or perhaps you've purchased a new battery and want to verify its capacity? If so, this app is just what you need! Capacity Info will assist you in determining the remaining battery level as well as the actual capacity of a new battery. Additionally, with this application, you can view the capacity in Watt-hours (Wh), the number of charge cycles, temperature, and voltage readings of the battery. You can also find out the charging and discharging current, and receive alerts when the battery reaches a low level (which you can adjust), when it hits a specific charge percentage, or when it is fully charged (Status: "Charged"). Moreover, this app provides notifications for overheating or overcooling of the battery, and allows you to check the maximum charging current limit (though this data may not always be accessible). It also offers an overlay display option and many more features.

P.S. This app is designed to consume minimal background power, so using it won’t noticeably affect your device's battery life. The application is open source, for those interested in exploring the code further.

Title: A Comprehensive and Reliable Companion for Battery Management

Having used this application extensively over the past few weeks, I must say it has become an indispensable tool for managing my device’s battery health. Unlike many other battery monitoring tools, it offers an impressive depth of information presented in an intuitive and accessible manner. I particularly appreciate the ability to monitor charge cycles and actual battery capacity, which has helped me better understand my device’s long-term performance. The option to view metrics in Watt-hours rather than just percentages provides a clearer picture of energy consumption, which is especially useful for power users. 

Additionally, the customizable alerts for charge levels and temperature thresholds offer peace of mind, ensuring I never accidentally overcharge or expose my device to extreme conditions. What stands out most is how lightweight the app is—it truly doesn’t drain the battery, just as promised. The overlay feature is seamless, and the fact that the app is open source adds a layer of transparency and trust that is rare in utility applications today. Overall, this is a thoughtfully designed, highly functional, and reliable app that delivers exactly what it promises.

FAQ:

Why does the app require permission to display over other apps?

This permission is essential for the overlay feature, which allows real-time battery statistics to be shown on top of other applications without interrupting your workflow.

Is the app really open source?

Yes, the application is open source, meaning anyone can review the code, contribute to its development, or verify its security and functionality.

Will this app consume a lot of battery in the background?

No, the app is designed to operate efficiently with minimal background power consumption, so it won’t significantly impact your device’s battery life.

Can I use this app to check the health of a newly purchased battery?

Absolutely. The app provides detailed information on current capacity, wear level, and other metrics, making it ideal for verifying the condition of a new battery.

Does the app support notifications for specific battery events?

Yes, but some advanced notification features—such as alerts for full charge, specific percentage levels, and temperature extremes—are part of the premium version.
