About this app

🏆 Battery Guru: Your Premier Battery Monitor
Battery Guru is the ultimate app for monitoring your phone's battery, providing insights into your device's power usage, battery health, and more, including charging speed, battery voltage, estimated capacity, and detailed statistics separated by screen on/off cycles.

📊 Battery Insights and Management
With this app, you can actively oversee your battery's capacity, configure alarms and reminders for battery level, temperature, and increased usage, while also gaining real-time usage statistics. The wide array of features at your disposal allows you to seamlessly monitor your battery's performance. Alarms serve as a valuable tool, alerting you when your battery reaches specific temperature and level thresholds.

🔋 Battery Health Monitoring
Battery health refers to the condition and performance of a battery, 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 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.

By actively monitoring your battery's well-being, you can take proactive steps to ensure it remains in optimal condition. Battery Guru employs its proprietary algorithm to estimate battery capacity, which includes a comprehensive analysis of past battery charging history for enhanced accuracy. With each charging cycle, Battery Guru becomes more adept at precisely estimating battery health. While battery health is subject to fluctuations due to temperature changes and aging, Battery Guru strives to provide realistic statistics rooted in the app's measured past battery history.

📈 Overall Battery Statistics
Battery Guru provides a wide range of battery statistics suitable for all users. To ensure user understanding, the app includes informative tip cards that describe each functionality, helping you grasp the meaning and behavior of your battery.

These features include:
• Measuring battery capacity with support for dual battery configurations.
• Obtaining estimated battery health at any time.
• Setting battery level and temperature alarms at configured thresholds, allowing the app to notify you.
• Monitoring application battery usage and wake-locks since the last unplug.
• Checking time until a full charge and remaining time until your battery reaches 0%.
• Monitoring deep sleep and awake time to understand when your device remains awake when the screen is off.
• Receiving detailed ongoing notifications for real-time battery statistics.
• Saving your phone's battery charging and discharging history.

I was using Gsam and wanted to try something different. This and AccuBattery seems highly recommended. UI interface seems a bit cluttered, hard to know what info is more important. I probably care the most about %/h. I suppose in the end, most people prob just want to know battery time is left which is impossible to predict. The Widget is quite disappointing. Just % with a circle, same thing shown on every phone in the top corner. It would be nice to show details like the notification

Hi, nice app, I'm on pixel 8 pro running despair kernel, so being able to monitor battery and provide feedback is vital. One suggestion, that I would find very nice, if implemented, would be; being able to hide statues statusbar icon without hiding notification, or maybe a blank icon could get the job done. Thank you for the updates, and happy holidays to you and family. 🙂

Thank you very much for review😊. Notification cannot be show without icon, only way is to have a blank icon that takes space. 😊 Happy holidays to you and your family as well 😊

I really like this app, and I want to subscribe, but I can't deal with the fact that it completely ignores your custom notification levels for its own. I set my notifications at certain charge levels for a reason, and the app ignores them, sending me an notification EVRY PERCENT above their chosen level. Unacceptable. In addition, the widget is useless. It's a percentage, nothing else. I have that in my status bar.
