Something I still LOVE about my Note Edge is that the battery charges incredibly fast, usually less then an hour from 5% to 100.
I have a Note 5 and every time I go to charge the battery, it takes nearly 90 minutes. There are times I plug in the charger and it will still take an hour when it's 50% or so and that is on fast charge.
I have a Samsung battery charger for my Note Edge and Note 4 with lots of extra batteries but these phones charge so fast that I often just charge the battery in the phone.
