For the past month, my Note 5 battery has been draining quickly. Over the weekend, It died because it wouldn't charge at all plugged into the wall with the original charger or other chargers. On my drive to work, it charged VERY slowly in the car and has gotten up to 30% after 9 hours plugged into my work computer via USB.
I have done a soft reset.
I have done a partition cache wipe.
I will do a factory reset if necessary, but don't want to if it won't help anything.
What should I try next?
