As we mentioned in our what to expect from the Galaxy S8 article, the Galaxy S8 and Galaxy S8 Plus might feature a 3,000mAh and 3,500mAh battery respectively. 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.

What it doesn’t reveal is who actually made the cell. Samsung has reportedly been working to diversify its battery cell supply chain for the Galaxy S8 following the disaster it suffered due to the Galaxy Note 7. It’s believed to be sourcing batteries from Samsung SDI, LG Chem, and Japan’s Murata Manufacturing Works.

Do you think a 3,500mAh battery will be enough for a 6.2-inch handset with flagship specifications or would you prefer if it had a bigger battery? Let us know in the comments below.
