The Samsung Galaxy Mega 6.3 packs in a massive 3,200 mAh battery, which isn't much bigger than the Note 2′s battery, but is enough to keep you going for a long period.
In terms of benchmark performance, the Galaxy Mega 6.3 is no slouch. Although it scored mediocre in most tests, it tied the Galaxy Note II in many benchmarks. However, for daily use, the Mega seems to work fine for activities like: switching between apps, opening applications, playing games, and returning home.
At the same time, the call quality of the Galaxy Mega 6.3 shines seems quite good. The rear speaker for speakerphone and the earpiece speaker are both quite loud, offering crisp and clear audio.
