    Default Moto X Won't Charge after Drain to Zero?

    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 (), 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.

    Lithium batteries are very fragile things. The chargers have to be very smart and cover for a lot of things that NiCad NiMiH etc did not have to worry about. Recall the spate of fires with Dell and other laptops a few years back. Well, discharging to an actual zero level is another dangerous thing for them.

    Although, what you are referring to as Zero, would actually be a fake-zero controlled by the charger and the charger would not actually let the battery drop below about 10% remaining charge.

    Manually turning the phone off - wait - on would most likely have reset it as the auto shut off is not a full shut down for everything.

    It's all good, the phone charging system is working exactly as it should.

    I get that it's doing this to protect the circuit, but why only sometimes? And, why last night but not this morning? Also, this phone supposedly has an LED that lights when this instance occurs (not enough juice to charge) but that didn't happen either.

    I never powered on or off the phone. Simply removed from the wall charger (after 6 hours on still with 0%), tried to boot with no response, then placed back on the wall charger a second time which got the charge going. If physically just hitting the power button a couple of times with no response somehow reset how the phone accepted a charge then so be it. Still kind of strange.
