Are you managing your battery the right way? Smartphone batteries inevitably degrade with use. However, it's hard to tell exactly when it started getting worse, or if its current condition is normal. Battery Train automatically records every single moment of charging and discharging, allowing you to understand your battery status at a glance. [Key Features] ▸ Automatic Battery Logging The app automatically logs your battery status every 5 minutes in the background. Your history builds up continuously without even having to open the app. ▸ History Graphs Check your charging and discharging curves with 24-hour, 7-day, and 30-day graphs. You can see at a glance exactly when your battery drops sharply. ▸ Battery Health Analysis By analyzing the discharge rate, the app calculates a battery health score. If your battery health is declining, you can prepare for a replacement in advance. ▸ Smart Charging Alerts • Immediate alert when the battery drops below your set percentage (e.g., below 20%) • Alert when reaching your target percentage during charging (e.g., unplug advice at 80%) Prevent overcharging and deep discharging to extend your battery's lifespan. ▸ Dark Mode Support Automatically switches between Dark Mode and Light Mode based on your system settings. [Recommended For] • Anyone who wants to extend their smartphone's lifespan • Anyone curious about when their battery drains the most during the day • Anyone who wants to know the perfect time for a battery replacement • Anyone looking to fix their overcharging habits • Anyone experiencing sudden and rapid battery drain [What is Battery Health Score?] Battery Train calculates a health score by analyzing your discharge rate over a certain period. A higher score means your battery is in good condition, while a declining score suggests that battery aging is underway. [Notification Permission Guide] Notification permission is required to use the charging alert feature. You can change this permission at any time in your Settings. Start managing your battery right now.
