There is space for a pen, but not a headphone jack?
NFC is useful for pairing bluetooth speakers, for example. Probably more so than for paying for stuff using a massive ipad..
That looks like two stacked batteries, to give +/- 3.7V with a ground center?
Having the dimensions of the pack would be great, making it easy to find suitable replacements!
Don't pry anything off! Desolder the bad port!
If you pry, you most likely will lift the copper traces and ruin the very traces you will need to solder to.
