Bluetooth Battery Monitor Pro

★★★★★ Does exactly what it's supposed to do and does it well. Paid version is very much worth the asking price for the extra features. Without an option on android to report actual headset battery usage, this is the next best thing. If I were to nitpick, I'd wish for prettier graphics on the notification icon and widget itself. But what really matters - functionality - is perfect. I'd highly recommend this to anyone uses a Bluetooth headset with their android device.

★★★★★ 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.

★★☆☆☆ S**t. It's just an ordinary timer that it's not actually estimate battery life. I just lost my money because this s**tty app. No real Bluetooth battery besides an Android Oreo. F**c you scammer dev.

★★☆☆☆ This is simply a manual timer that you will have to reset manually every time you recharge your headset! 😠
