This is according to a filing with the National Telecommunications Agency ANATEL in Brazil in which it has been revealed that the phone could pack a 4,000mAh battery. This is actually in line with what we’ve heard, although a previous report did suggest that it might feature a 3,850mAh battery instead.
Given that the Galaxy Note 8 only had a 3,300mAh battery, either way the jump to 3,850 or 4,000mAh is very much welcome. Exactly how much additional usage time this translates to remains to be seen, but your mileage may vary depending on how you use your phone, but regardless the upgrade should make it last substantially longer.
Samsung has confirmed that the Note 9’s unveiling will take place on the 9th of August, so be sure to check back with us then for the details.
