So I had originally bought the black note 4 the day it came out, on the 23rd. Later returned it for a white one on the 1st of this month, but now my battery drains so much at night while my husbands note losses 2-4 percent... Also the WiFi drops, my question is.. Could I still return it? Do they count the original day it was purchased or since I returned it the would start counting on the 1st, by the way I got it at best buy... Thanks.
