Batt is the closest I've found
Thanks for the recommendation, I'll check it out. Any chance you used Plus Plus Battery?
I haven't, but did just now. It definitely shows more! I noticed Batt shows a percentage for battery capacity right away, but I guess Plus Plus Battery needs to calculate it over time?
I think accurate results are from a zero to full charge monitoring process. i.e, you need to put the phone through one continuos charging cycle to 100 percent before you can get reliable estimates.
