My Note 2014 is coming on 2 yrs. Lately I only get about 2 hrs SOT. Standby drains quickly even in airplane mode. The other day I got the red x when charging. I unplugged it, then plugged it back in. I experience battery drain even when the tablet is off. Today I was at 30% and turned it off. About 5 hours later when I turned it on, I was at 19%. About 2 minutes later, I was at 18%. Is this a battery issue?
