Battery Guru is your go-to app for in-depth battery monitoring including battery health (current mAh level) battery voltage and battery temperature. By tracking real-time power usage charge efficiency and battery wear it helps you better understand the battery charging and discharging state on your device.
Most battery information is derived from the charge controller with our app extending its capabilities by applying established scientific formulas to calculate additional metrics.

📈 Battery Statistics
• App usage: We measure foreground app battery usage on your device (i.e. the time when you are interacting with the app)
• Charging electric current & discharging electric current: Shows real-time updates of charging and discharging electric current and represents them on a live graph. You can also check the minimum maximum and average charging and discharging electric current
• Charging speed & discharging speed: Displays real-time updates of charging speed and discharging speed measured in mAh per hour and percentage per hour respectively
• Charging time & discharging time: Provides estimates of the remaining time for both charging and discharging sessions giving you a clear view of how long it will take to reach a full charge or depletion
• History data access: View all past sessions recorded by the app and gain insights into your phone's battery charging and discharging history
• Type of Charging: Detects and displays the charging method used for your device whether it's AC USB dock or wireless
• Estimated Capacity: Based on historical data the app generates an estimated capacity that reflects the battery's health at a given moment
• Monitoring deep sleep and awake time: Understand when your device remains active while the screen is off
• Dual battery support: Monitor and manage battery performance on devices with dual battery setups

💊 Battery Health
Battery health refers to the condition and battery performance which can deteriorate over time and usage
It is important to monitor and maintain battery health for several reasons:
• 🚀 Performance: As batteries degrade their ability to hold a charge and provide power diminishes leading to reduced battery performance and shorter battery life
• 🛡️ Safety: Batteries that are in poor condition or have been damaged can pose a safety hazard such as overheating or exploding
• 💰 Cost: Replacing batteries can be expensive and maintaining good battery health can prolong their lifespan and save money in the long run
• 🌍 Environment: Proper disposal of damaged or depleted batteries is important for environmental reasons as they can release harmful chemicals and contribute to pollution

Pro Tip: To maintain good battery health avoid extreme temperatures and monitor usage to prevent overcharging or over-discharging.
