Battery AlertPro is a battery monitoring app developed by Digimaster for Android devices. It is a simple, easy-to-use app that notifies users to charge or unplug their devices based on customizable battery percentage settings. The app can monitor battery levels and send notifications even when it is not running. Consistently charging the battery at optimal levels between 40% and 80% can significantly improve the lithium-ion battery's overall life. In contrast, frequent low discharging to full charging past 100% can put unnecessary strain on the battery, shortening its life. Battery AlertPro helps prevent over and undercharging with custom percent levels for charge battery notification and unplug charger notification. The app is equipped with a battery temperature alert feature, which helps maintain the battery's overall health by keeping it at a stable temperature. Battery AlertPro also offers a range of customizable settings, including a "Do Not Disturb Time" feature and the option to choose between notification by app window or standard notification messages. The app comes with default voice alarm sounds, but users can choose their own ringtones for all alarms. Overall, Battery AlertPro is a helpful app for anyone looking to improve their device's battery life and charging habits.
