About this app

Bluetooth Battery Monitor – is a widget-only application that provides you with an estimated battery level of your Bluetooth headset (or another device) and calculates how much time is left of its battery life. To calculate these values, widget monitors your Bluetooth device activity and uses Active time and Standby time that you should enter on the configuration screen. You can take these values from user manual or specifications of your Bluetooth device, or use widget itself to count active time for you.

This application is compatible with all Bluetooth devices, that support A2DP or Headset profiles.

FEATURES:
- Battery level icon in status bar (optional);
- Warning notification if your Bluetooth device runs low battery (optional);
- Available 2x1 and 1x1 widget's sizes;
- You can assign your desired names to your Bluetooth devices;
- Easy to use and configure;
- Ability to backup and restore widget's data;
- Battery friendly.

USAGE FOR 2x1 WIDGET:
- Double tap on battery icon or percentage: reset battery level and remaining time values;
- Single tap on device name or remaining time: open configuration screen.

USAGE FOR 1x1 WIDGET:
- Double tap on bottom element to reset battery level and remaining time values;
- Single tap on top element to open configuration screen.

For more information, please refer to in-app help guide.

ATTENTION:
This widget was developed first of all for Bluetooth devices, which do not report the battery level through Bluetooth protocol, but it is compatible with all Bluetooth devices, that support A2DP or Headset profiles. Do not be disappointed if you were looking for an app which can display battery level from a headset itself through Bluetooth protocol - this widget is not supposed to do it.

NOTE:
If your Android device does not correctly report Bluetooth playing state, "Force A2DP detection" feature should help, but note that this feature will not force the widget to update immediately when you start or stop playing music, but widget will count time accurately and display correct playing status after every periodic update (every minute). So just wait about one minute after you start or stop playing music, the widget should display correct status, it will not effect on the accuracy of counting battery life, just a short lag of displaying correct state for devices which does not act according to Android documentation.

Ratings and reviews

this a great app for monitoring the connected time of your bluetooth devices, when they don't report the actual battery level accurately or timely. my headphones go from 90% to 10% to dead within about a minute. this widget quickly allows me to see how much time I have remaining before it will switch off. yes, it's not 100% acurate, but it's far better than the battery level reported by the system

While using the free version of this app, I was so blown away by its accuracy that I purchased the Pro version to enjoy its frills. This app essentially works like a “Timer” to calculate the remaining time of the battery of your BT (Bluetooth) device using a count-down of the “Active time and Standby time” that you provide . So if you say that your headset has a battery life of 5 hours, it will report 4 hours -27 mins after using your headset for 33 mins — and so on. I now use a separate widget for each of my BT device and a 100% satisfied user. I surmise that those who have rated this app low, have NOT quite read “how this App works and how to configure this” in detail.

Just a timer to remind remaining play time set by the user himself. Not recommended.
