This confirms a 3,500mAh battery for the Samsung Galaxy S8 Plus

Almost everything has leaked about the coming Samsung Galaxy S8 and Galaxy S8+. Now also the battery for the bigger plus version has leaked.
We’ve now spotted a leaked image of what appears to be the 3,500mAh battery of the Galaxy S8 Plus. If it’s the real deal it does confirm several things about the new flagship.

First off, it confirms rumors that the larger variant is going to have a 3,500mAh battery. That would be a concern for many who might think that it may not be enough. The markings on the battery itself reveal that the cell was made in Korea and assembled in Vietnam by Samsung SDI.

Personally I'm not so worried that the battery capacity is not enough, because I'm sure Samsung has added a really fast charging technology that makes it possible to charge it for a few minutes and get quite much juice to go.
