It looks as though we might well be getting a tougher version of the Samsung Galaxy S9, as a specs list for the Samsung Galaxy S9 Active has just leaked, revealing that it has a 4,000mAh battery.

That’s significantly larger than the 3,000mAh unit in the standard Galaxy S9, or even the 3,500mAh one in the Samsung Galaxy S9 Plus, but it’s believable, as it’s in line with the Samsung Galaxy S8 Active.
