Helped me figure out which cords were bad, and even seemed to "fix" those bad cords... I'm putting that in quotes because I'm not sure what happened, but I had two cords that were drawing power and killing the battery and after measuring them with this app, they seemed to start charging again after being unplugged and then plugged back in.
Unfortunately in MM the measured data not shown on status bar, only the permanent logo is there though the permanent logo unchecked in the setting configuration!
Almost airways displays 1400ma. Either positive or negative, chargers and cables don't matter. App doesn't seem to work.
Not all cables and chargers are created equally! Very useful in finding the best charger / cable combo so you don't have to wait hours to charge your device!
It helps me tell which cables and chargers are working good and which ones to throw in the garbage. Like it but it tries to make you buy it every time you open it. One star subtracted for that.
Seems to do what it's supposed to do
* Fix for LG G6 battery health bug
* Language updates
* Bug fixes
