This just in - the National Telecommunications Agency in Brazil confirmed the Galaxy Note9's massive battery in a leaked document.

The certification document doesn't reveal much but it confirms one of the main features the Galaxy Note9 will boast over its predecessor - the 4,000 mAh battery. Rumors about the large battery capacity have been going around since April and the bit was later confirmed by a different source in June. Now, a month later, ANATEL is here to solidify these claims with an official document.

We think that it doesn't get any more legitimate than this. We hope that the big battery will come with some competing charging tech or at least support for Quick Charge 4.0 and beyond since we already know that the wireless charger that will be introduced alongside the handset won't bring any ground-breaking charging speeds.
