Attempted to recalibrate the battery % on my X yesterday doing the usual drain to zero & charge while off after auto-shutdown. Left on the charger overnight (6 hours) & would not boot in the morning. Plugged back on the charger and still showed 0% battery
confused
, but then began charging as normal. 2.5 hours later at 100% and back to normal but not sure what happened. There was not a bad connection as the phone screen lit up initially last night indicating it was at 0% and would begin charging. Anyone else experience this? I've done this in the past with another X so not sure what to think with this one. First time attempting on this phone.
