I have learned quite a lot about battery and charging behavior of my phone through this app, and I continue to use it mostly to monitor battery and charging performance.
The status page is erroneous (big time). 1. When NOT charging the phone, NO USB charger plugged in, the app reports Charging Unplugged in red text and mA flow as a positive number in green text. 2. When the phone IS charging, with USB charged plugged in, the app reports Discharging AC in green text and mA flow as a negative number in red text. The graphs reports a different but more coherent status. Still the app is a disappointment considering I read the positive reviews and thought I'd give it ago, just to be surprised with a erroneous status page, warranting zero confidence to test out the others features.
Discharging and charging status is the wrong way round, also if you set widget to average % per hour since last measure it's giving incorrect readings.
It's awesome when it works! Great information to keep an eye on your phone. It doesn't appear to work on Android 8 Oreo yet?
Very good and informative app. Unfortunately, the widgets often do not update information as they should. Often a restart is needed to get them working until the next time they stop.
Extremely useful. Using it with a Note 4 and large battery. Have every reason to believe the mV ratings are reasonably accurate. Appreciate the logged information - and that mV rating when off charger gives the only solid idea of where the charge state really is when close to depletion. Having an alarm go off above a particular temperature would be a useful additional feature - have fallen asleep with it charging on the bed before, not good. I don't expect it to go beyond what the hardware supports.
