★★★★★ Alana Emery · Jan 30, 2024

Yep battery charges can confirm phone does have battery

★★☆☆☆ Richard Glenister · Jan 31, 2024

It's all really rather random. Sometimes it records trip data sometimes not. Sometimes it creates battery test results without prompting which is its own trip data is to be believed would have been while I was driving. Sometimes it won't connect to the device at all. At the end of the day leave me wondering if the data it generates is random or can it be believed?

Why do you need my Gps location to test battery? This is kind of Chinas Spying Program? Because Bluetooth does not need Gps to connect! My JBL soundbar, TV set, keyboard+mouse, LG washing machine and even Car don't ask for Gps to work via Bluetooth and they work! Remove GPS permission!

★☆☆☆☆ Bartłomiej Stachura · May 14, 2023

The app keeps disconnecting when "mobile data" is on. After turning off "mobile data" and restarting the app, the Bluetooth connection works as it should.

★☆☆☆☆ Ion Panescu · Sep 1, 2025

Results differ from other the ones shown by other tools. I don't believe this app is accurate: the same voltage is interpreted as 100% and 80% SOC; the range of sohs is from 40 to 70%. The same goes for internal resistance from 2 to 4.5 mOhms. I would return the hardware, but I keep for monitoring only the voltage.
