Battery Drain Check

Battery Drain Check helps you understand what drains your iPhone battery faster in real-life usage scenarios.

Run guided battery drain tests for common situations such as idle screen-on usage, video-style playback, camera preview, navigation/location workload, gaming-style graphics and Personal Hotspot testing. The app estimates battery drain rate as % per hour, saves your results, compares tests, generates reports and gives practical optimization tips.

Key Features:
• Guided battery drain tests
• 15, 30, 45 and 60 minute test durations
• Real-life scenarios: Idle, Video, Camera, Navigation, Gaming and Hotspot
• Estimated battery drain rate in % per hour
• Battery Drain Score for quick result interpretation
• Test history and scenario comparison
• Charts for battery drain trends
• PDF and CSV report export
• Personalized Battery Optimization Plan
• Practical battery saving recommendations

Battery Drain Check is useful if you want to understand whether screen brightness, camera use, navigation, gaming, hotspot usage or other scenarios may be affecting your battery life.

Important Accuracy Note:
iOS does not provide third-party apps with direct access to battery current, voltage or hidden hardware power metrics. Battery Drain Check uses public iOS battery level and battery state APIs to estimate battery drain during controlled foreground tests. For best results, keep the app open, unplug the charger and run longer tests of 30–60 minutes.

Battery Drain Check is designed for iPhone users who want a simple, visual and practical way to compare battery drain in everyday scenarios.
