I appreciate the above post. But I can not charge the phone to 100% which is the issue, therefore I can not even do step number one. i can only charge to 97%. I should have been more specific, I apologize. The battery icon (accurate battery) is only showing 97% immediately after the full charge pop up comes up on the phone and I immediately pull the power cord.
I sat here and watched the battery calibration app after trying your above-mentioned instructions. My phone, according to battery calibration, is at 100%, so I hit the calibrate battery icon.....calibration succeeded. I then pull the plug.....accurate battery mod says it is only 97%
