# Battery Guardian — Google Play Description
Battery Guardian is a battery alarm and charging monitor that helps you track your phone's battery level, charging status and temperature. Set alerts for the battery levels that matter to you and stay informed while your phone charges.
## 🔋 BATTERY ALARM
Set a battery alarm at any percentage from 20% to 100%. Choose whether the alert triggers while your battery is charging or discharging. Get notified with the sound and vibration you choose when the selected level is reached.
## ⚡ FULL CHARGE ALARM
Receive an alert when your battery reaches 90%, 95% or 100%, helping you remember to unplug your charger when you want to.
## 🔌 CHARGER CONNECTED & DISCONNECTED
Know when your charger is connected or disconnected. Useful if a cable is loose, charging stops unexpectedly, or you want to monitor charging activity. These alerts can work while the app is closed.
## 🌡️ BATTERY TEMPERATURE ALERT
If your device provides battery temperature information, set a temperature threshold and receive an alert when the reported temperature goes above it.
## 📊 BATTERY INFORMATION
View the battery information provided by your Android device, including battery percentage, charging status, power source, temperature, voltage, battery technology and battery health when available.
## ⏱️ CHARGING MONITOR
See how long your current charging session has been running and how much the battery percentage has increased.
## 📈 BATTERY HISTORY
View a local chart of recent battery levels. Your battery history is stored on your device and can be cleared whenever you choose.
## 🎛️ CUSTOMIZE YOUR ALERTS
Choose your alert sound, vibration and alert style. Battery Guardian supports light and dark themes.
Available in English, Français, العربية, Español, Português and Türkçe, with right-to-left support for supported languages.
## 🎁 OPTIONAL EXTRAS
Some additional features can be unlocked temporarily by watching a short rewarded advertisement if you choose, including extended battery history, using your own ringtone or imported audio file for alerts, and longer vibration patterns.
Core battery alarms, alerts and battery information are available without a subscription or premium plan.
## ✅ HONEST BY DESIGN
Battery Guardian reports the battery information provided by Android and your device. If a value is not available, it is shown as unavailable rather than invented.
Battery Guardian does not claim to repair a battery, increase battery capacity, extend battery lifespan or physically cool your phone. It is designed to monitor battery information and provide battery and charging alerts.
## 🔒 PRIVACY
No account or sign-in is required. Battery Guardian stores your battery history and app settings locally on your device and does not upload your battery readings or history to its own servers.
Advertising is provided by Google AdMob and may involve data processing for advertising and related services. You can review available privacy choices inside the app.
## 📱 BACKGROUND ALERTS
Charger connected and disconnected alerts can work while Battery Guardian is closed.
Battery level and temperature monitoring require Battery Guardian to continue monitoring in the background and may use an ongoing notification. You can manage this behavior in Settings.
Some Android manufacturers apply additional background restrictions. If alerts stop arriving, check your device's battery and background-app settings and allow Battery Guardian to run in the background.
## 🌐 WORKS OFFLINE
Battery Guardian works offline for its core battery monitoring and alarm features.
No location, contacts, camera, files, photos, account or sign-in are required.
Battery Guardian gives you a simple way to monitor your battery and receive charging alerts without misleading battery claims.
