II am using Galaxy Note 3 since 1 year and I am really a very heavy use who does so many calls a day and have whopping 35 gmail accounts always on, skype and whatsapp running all the time and so many online activities and this phone is the only one that lasts through the day.
After an year the battery got weak but I easily changed it at home as it is user replaceable - ah the joy of having a phone with removable battery - take that Apple phones who charge 7-8k for replacing battery! This is a rock solid phone and none of its parts will fail - just make sure not to use it roughly and always have a metal bumper case around its sides.
The bumper case will serve two purposes:
it will make your phone look cool
got silver one for my black note
and elegant. Second it prevents the chrome from getting damaged.
Verdict - This is the best phone on the market till now that does not compromise on performance and battery life.
