Battery of note 4 is 4100 mAh
No other company can give such a hugh battery that actually last longer than any other 4000 mAh phones.
Eg Yu Yunicor 4000 mAh, Gionee A1 4000 mAh
But they last for 6-8 hours if used continuously. But not the same in case of Note 4 because note 4 surprisingly hold its charge for 2 days with heavy uses.
If you are a pro-gammer or pro-user, u must go for it.
