Please look at the end of time axis. During the charging, the battery level jump from 78 to 100 suddenly.

I found similar jumping several times, and I did a calibration by completely discharging the battery. During discharging, the last 1 percent is supper durable. However, after a couple of days, the jump reappear again.

Any ideas?

I've noticed that as well anytime I charge from anything except dead 0 it jumps from 80 to 100 from 0% it charges smooth to 100

Yeah I've noticed this as well. It was very surprising because my old phone would take hours to charge but the Moto X took almost 1/3 of the time. But then battery does last long after the full charge so NO COMPLAINTS here :good::good::laugh:

yeah i feel like the battery percentage is not accurate at all on the moto x. I compared it with mV voltages in battery monitor pro and its always off...

your phone is guessing what your battery percentage is. if you want to fix it, drain phone down until it completely dies. then charge it to 100% without turning it back on. It will recalibrate your phone battery stats and you no longer will have the phone jump from 80-100% when charging.

I have done that twice. This symptom reappears after several days.
