About this app

Would you like to protect your Android device & battery health?

Then use Charger Alert™ - the battery saver app that helps extend your battery life and prolong your battery health by alerting you when the battery is too low, the temperature is too hot and overheating, or your device has finished charging so you can unplug it.

Charger Alert can also warn you with an alarm if somebody unplugs your mobile phone or device from the battery charger, or if there is a power outage while it is connected and charging.

You can use Charger Alert to always show the battery percentage remaining and charging status as a notification in the status bar, on your lock screen, and as a home screen battery widget.

Keep your Android device and battery safe with Charger Alert™.

the settings are terrible it doesn't do like the video says it's not working correctly on my thang however the alarm connect it with my interface just fine. and as it was fully charged alert went off and blessed as loud as it could be sounds similar to some sort of police we can't change that I don't know how it's not working like the instructional video there's no manual well there is but I can't figure it out. I can't read the fine print it's too tiny. it's only good to alert Johnson out.

It works & covers key batt. stats. Charger Alert also has dynamic icon theming, which not even big companies are willing to include in their apps. Hopefully, Charger Alert will one day have an option for timed alerts, but it's supported well & the customer service is quite good.

The best solution since Android no longer lets you know your battery is low. Almost perfect and after a few setting adjustments it's the best one I've found; way ahead of the others
