Just when I thought my problem was gone the phone showed me how wrong I was. After overnight charging Thursday into Friday both the battery monitors (icon and the app one I installed showed 100% charge till past lunch time. I of course did not believed it and removed and re-installed the battery. 71%! Expletive, expletive.
I guess it's time to try the .7A charger theory. Any suggestions on which one I should source?
