Dr.Battery shows you the values stored in the chip inside the battery.
Even though you can't calibrate the battery on Pre3 and Veer I still think it's helpful :-)
Haha, yes, sorry somline! That's was poorly phrased. It is still helpful, thank you!
From using it on older models and seeing the Dr. Battery recalibrate results, I'd just gotten to not really trusting those chips after some time anymore. It does still show some useful stats for troubleshooting, though!
