I just updated my note 5 with the latest software update with the November security patch. Since then, as soon as my phone reaches 15 percent, it starts to drain drastically at about a percent every 10 to 15 seconds.
I let it drain all the way to 2 percent within a minute or 2 and then plugged it in. The number instantly jumped to 15 percent again.
Something strange is happening. I've tried the factory reset but didn't help the issue.
Any help would be greatly appreciated.
