Samsung has confirmed that its Galaxy S3 will be able to support a 3,000 mAh battery pack to replace the smartphone's current 2,100 mAh battery.
The new battery option, which is priced at $64.99, has a NFC chip integrated and sports a new back cover to contain the larger battery.
While it's not clear exactly how much of a battery boost the new pack will deliver, it should be able to endure heavy usage throughout a full day, while average users should see it last for at least two full days of normal usage.
For some perspective, the extended battery is 100 mAH short of matching Samsung’s phablet, its Galaxy Note II, which boasts a 3,100 mAh battery pack to help power its 5.5-inch display.
