Battery Charging Alert 4+

Accidentally unplugged your power cable without noticing and now your battery is dead?
Want to take care of your device and maintain your battery life?
Confused about the status of the system's new battery optimization and on-hold function?
Love the assuring sound of your iPhone's chime when you plug it in?

Battery Charging Alert is just right for you! With the app, you can receive alerts for when your computer is plugged in or unplugged, and when your battery percentage reaches a preset level, so you know when to plug in your computer to keep it from dying or to unplug it and save your battery life.

- colorful battery icon and text on your status menu bar let you know the status of your battery with just a glance.
- real-time display of when the computer is plugged in or unplugged, battery percentage and health, as well as warnings of critical states in colors.
