Samsung again advertised the battery, just two years after the disaster Note 7

Samsung is expected to announce a new Galaxy Note 9 phone in an event in New York on August 9 and it seems they are ready to return to the phone battery.

A teaser shows that the phone will have a bigger new battery.Some rumors say the battery can be up to 4,000mAh, becoming the largest battery ever put into a Note device.This is a significant change after the Note 8 and the Note 7 of 2016.

Note 7 uses 3,500mAh battery but is eventually withdrawn due to continuous explosion.American airlines also banned passengers from carrying this device due to concerns about flight safety.After spending a year apologizing, Samsung temporarily put ambition to put big batteries when in 2017, they launched the Note 8 with only 3,300mAh battery capacity.

Perhaps it was time for them to feel confident enough not only to put a large battery into their new phone, but also to use it as a key element to promote.Looking at the significant upgrades between Galaxy S8 and S9, Samsung needs to do something to make the new Note not just a Galaxy S9 + version with an extra stylus.

This is a promotional video of Samsung's new battery.Hope their big dream in Note 9 this time will not bring great disappointment and not follow the trail of Note 7.
