I put a new battery in my Galaxy Note Edge but it won't charge past 85%.

[AC Question]

I'm sure it is fully charged, so why does it only show 85%?

Leave the charger plugged in overnight. If that doesn't fix it, you have to recalibrate it (Battery Calibration (Root) works nicely), but the phone has to be rooted to recalibrate the battery file.
