Battery Guru is a comprehensive app that provides detailed information about your phone's battery health, usage, and lifespan.

With this app, you can monitor your battery's capacity, set alarms and reminders, and get real-time statistics to your usage.

🪫 Say goodbye to low battery situation all time and hello to Battery Guru - the ultimate Android app for monitoring your phone's battery.

🏆 Battery Guru is a helpful tool that provides insights into the health of your phone's battery. By monitoring your battery's health,
you can take proactive steps to ensure that it remains in good condition and performs optimally.

🔋 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.

* To maintain good battery health, it is recommended to avoid exposing batteries to extreme temperatures or moisture, and monitor usage to prevent overcharging or draining the battery too much.

💡 Battery Guru offers several features to enhance your phone's battery life, including the ability to set fixed charge and temperature alarms for extending battery lifespan.
Additionally, you can monitor application usage and wake-locks since the last unplug to further optimize battery performance.

These features include:

• Measure real battery capacity (in mAh) and dual battery configuration is also supported.
• Set charge and temperature alarms to prolong battery lifespan.
• Monitor application usage and wake-locks since last unplug.
• Check the remaining charge time and use time.
• Check the percentage of deep sleep and awake time.
• Get detailed ongoing notification for real-time battery statistics.
• Monitor your phone’s battery charging and discharging history.
• Set reminders for battery temperature, charging limits, and abnormal battery usage.
• Get estimated battery health at any time.
• Battery Widget and Status Bar Indicator Battery Guru also offers a widget that displays your phone's battery information on your home screen,
including the remaining charge time, battery level, and temperature. You can also choose a status bar indicator based on your needs,
such as electric current, temperature, battery level, or a combination of them.

Very detailed and useful battery usage. It helped me identify some battery drain issues and provides useful app running times. Very good at detecting wakelocks, both full and temporary. I would pay for a pro version to help support the developer, but I don't find the optional subscription service to be very well priced. Still, very well done app and definitely a good utility to monitor past and present battery usage for free.

Thanks for your review, appreciate. App is completely free and all features are unlocked, I think it's the best for users. Subscription is there just in case you want to reward me for the work and time I spent here. Thanks again 😁😁😁

This app is absolutely essential to estimate how good and healthy a new phone is for observation, maintenance and research purposes. If you purchased a new mobile phone and wanna keep track of it's battery health and potentially prolong your overall battery health this is the best app to get as of right now. This could change though. It's also incredibly difficult to set up the permissions list to access key features. It isn't explained eell

UI looks nice for s bit, but then you realize that it's extremely cluttered and disorganized. Looks like same info is given over n over n over. Wish it was less "busy". EDIT - for example, in the "discharging" tab, there are 4 rows of total 11 tiles showing me different time records and estimates, plus all the % tiles. It gets overwhelming and not optimal for "at a glance" viewing. Maybe you can make each section collapsible; retaining their state across app launches. I'll email.
