I have had my Note3 for several months. I still get great battery life and I use my phone daily. I have learned to let the battery life go as low as 1%, but never above 5% before I charge the battery. I do have a plethora of chargers and a power bank. I am very happy with the performance of the Note3 and highly recommend it. I have heard from a few Note4 owners that they do not get as much battery life because of the super high definition screen.
