Flash Charge is a free Android app developed by ChargeLabsy. It is a utility and tools program that provides users with scientific battery usage display, battery capacity measurement in mAh, and screen usage history. With its basic functions, users can easily understand the current power and available time of their mobile phones, as well as the basic information and current status of the battery, including charging status.

One of the highlights of Flash Charge is the ability for users to set different battery reminders according to their needs. This feature allows users to optimize their battery usage and ensure they never run out of power at critical moments. Another useful feature is the calculation of actual battery capacity in mAh, providing users with accurate information about their battery's performance.

Flash Charge also records the time point of the first charge of the day, allowing users to track their charging habits. Additionally, it records the average screen usage time and saves multiple days of records, enabling users to view their screen usage history. Furthermore, the app records the battery power condition at different time points and saves the records for three consecutive days.

As an independent developer, ChargeLabsy has designed Flash Charge with a focus on optimizing user experience. The app aims to provide user-favorite functions and features that enhance the overall battery management experience.
