Works ok but could be better. This is one of only two apps that ever existed on the Android system that records battery current when the phone is off. This is the only way to measure the performance of a charger without an external amp meter and the only way for wireless chargers. It's missing an important power graph and a voltage graph would be a plus. In dark mode, settings text are not visible. The FAQ section should be written a lot better. I would gladly do it for free.

EXCELLENT (love the graph view others apps are missing),... except... My phone's native screen off/battery saver seems to be killing any recording by THIS app when I leave the app, even if it's still running in the background (open apps list), despite my setting the system to ignore this app. Wish I could figure out how to fix this. Sucks that whenever I go back to it, it just starts over again, so no 1 or 2hour recorded graph. Otherwise, WONDERFUL!! Also, please add Time o'clock to graph. *Graph runs very stable on some devices & erratic on others, using SAME cord & block. Why?

Great app. Graphs for monitoring charge speed and times allow you to easily work out which chargers and cables are best for your device. As well as working out exactly which uses are draining your battery. The only capability that is lacking is the ability to log the data in a file, it would be incredibly useful to be able to look back over historical data.
