About this app

Battery Widget & Signal Finder is your all-in-one source for measuring and managing battery health, battery usage and battery capacity. Since your phone’s battery can be depleted due to constantly being on the lookout for a signal, this app includes a Signal Finder tool to help you quickly locate where a good signal can be found, ultimately sparing your phone’s battery.


However, the life of a phone’s battery can be extended significantly when consumers stay up to date on the best battery management practices and are equipped with the tools designed to help them achieve optimal battery performance. That’s where Battery Widget & Signal Finder comes into play.

Customize your own battery % alert notifications from 5 different alert conditions (fully charged, level drops to, level rises to, temperature rises to, and battery health condition);

⭐️ Desktop Toolbar Indicator
Various toolbar indicator circle/font styles that will show battery life level at a glance from your home screen;

⭐️ Color Themes
Custom battery color themes – customize battery widget's app color theme to your liking;

The app is free, so don't complain. Excellent app. Features can be turned on and off to suit your needs. Any concerns--conact the developer. Their contact is available same page where you want to post a negative review. I am sure the aggregate data from cell phone locations is given to cell phone signal maps' providers but that is unonimous is helpful to all--I've looked at such maps before and it was helpful to see what sort of cell phone coverage (2G/3G/4G) your geographical area has.

Easy install and set up. Selectable display options. Keep it simple, just a percentage remaining, at the top of the screen. For some reason, in spite of being toggled on in settings, my Android 9 phone's built in indicator doesn't display. This is an excellent substitute. Not too sure why my location is required though?

This app does a pretty good job of providing battery information that I like to know, such as battery tempurature and voltage. I like that it will notify you when the battery reaches a specific charge or discharge level that I have set. I do wish it could automatically shut off the charging when it reaches the level I set, but I understand there may be technical hardware reasons why that is not possible. I am satisfied with the app.
