After the recent update to 48A my phone has suddenly shut down with a 0% charge several times. It seems to happen shortly after the charge drops under 50%. I do not think the battery is actually fully discharged when it shuts down because it is back up to 80% within about 1/2 hour. I used to get a warning when the charge dropped down to close to 15% when the phone is supposed to go into a charge saver mode (I checked and that is active).
Has anyone else noted this issue? Is the battery charge monitor part of the OS?
