Battra: Battery Monitor

Make sense of how your phone charges and where its battery level goes throughout the day. Battra is a battery monitor that turns device readings and recorded history into clear, practical insights. Check your battery at a glance See live battery percentage, charging state, charging source and Battery Score. Add a home screen widget for battery level, temperature and the last update time. Estimated Battery Health Explore estimated battery capacity and health where your device provides enough information. Enter the manufacturer's rated design capacity when needed. Confidence and availability indicators help you understand the limits of each estimate. Charging monitor Follow charging current, voltage, battery temperature, estimated power and estimated charging time where supported. Review completed charging sessions and label your chargers or cables to compare recorded charging speeds across sessions with similar conditions. Battery insights and history Use battery graphs and charging history to spot patterns over time. - Compare this week's observed battery drain with the previous week. - Explore estimated runtime ranges when enough history is available. - Review recorded time at high charge levels or elevated temperatures. - Mark a change in your habits or settings and compare observations before and after. - Open a daily battery report and export recorded battery samples as CSV. App usage and Estimated Battery Impact With optional Android Usage Access, review foreground app usage alongside Estimated Battery Impact. These estimates relate usage activity to observed battery changes; they do not measure exact energy use by each app or prove which app caused a drain. Smart battery alerts Choose notifications for your preferred charge level, full charge, low battery, high temperature and abnormal battery drain. Alerts depend on notification permission, available observations and Android background behavior. Practical battery advice The Smart Battery Advisor provides battery optimization recommendations based on available readings and patterns. Follow guided troubleshooting for overnight drain, slow charging or a hot battery, and open relevant Android settings to make changes yourself. On-device analysis and controls Battery analysis and recorded history stay on your device. Choose your history retention period, clear saved history or export samples when you need them.
