Thank you for the follow-up...
FYI, my phone is an iPhone 5...
and, YES, I understand that there is an option to "Reset All Settings" (I just abbreviated it as "Reset All")...
My inquiry was to find a 'list' of each of the settings that would be reset, so I can capture my existing settings and create a guide so I can restore my original settings... I am sure you understand that "ALL" is not specific enough to accomplish this (because there will always be one of more settings that elude you)...
and, YES, I have held down the Home & Power buttons and continued to hold them down until the Apple appears... This has not resolved the battery power issue (BTW, if I do nothing, the iPhone does indeed 'die' when the battery indicator drops below 1%, EVEN though if I 'had reconnected power at 1%, it always jumps to > 55%) -- this indicates that there is an issue with the INDICATOR, BUT the system shuts down when the INDICATOR goes to zero, even if the internal power is really at > 30%...
I saw a suggested 'solution' to this battery indication issue that said: "the iPhone needed to have it's settings reset". My question is: "What settings do I need to capture BEFORE a reset, so I have a reference to restore my original settings."
What can't Apple publish a list of settings that are 'touched' by the "Reset All Settings" option? Why is this list not documented? Are the users supposed to GUESS? ==> Not a great way to document how the system works.
This is really a SIMPLE question, so why isn't there a straightforward answer???
