Is fast charging harmful to Galaxy Note 5 battery?
The official Samsung charger for Galaxy Note 5 in your box is actually a fast charger (adaptive charger). This is why you can charge Galaxy Note 5 in about 1.5 hours.
Fast charging is supported and enabled in Galaxy Note 5. You cannot disable it. This is different from Galaxy Note 4, in which you can disable fast charging if you are not comfortable with it.
Fast charging is achieved through elevated voltage (from 5V to 9V), not through increased current. The adaptive charger has a special chip to communicate with the battery (and the phone) to determine the proper output power depending on battery level and other parameters. Once the battery level reaches above about 50-60%, the charger will function as a normal wall charger and fast charging is essentially disabled.
Theoretically, fast charging may increase wear and tear to the battery cells due to higher charging power.
But technically, the impact is very marginal. You should not worry too much about it.
It may slightly shorten life span of Galaxy Note 5 battery. But the gains of shorter charging time usually offer more value for the phone.
