According to fresh gossip, Samsung's upcoming Galaxy Note 3 will pack a beast of a battery.
Citing "a person who says that he has just seen the engineering sample of the phablet first hand," Phone Arena reports that the device will feature a huge 3,450mAh battery.
If true, this will be a big step up from the batteries of the Galaxy Note 2 and the original Galaxy Note, which carry 3,100mAh and 2,500mAh cells, respectively.
In fact, it would become the most potent battery Samsung has ever squeezed into a smartphone. The Galaxy Mega, which launched earlier this year, holds a 3,200mAh battery.
Battery life is a major feature that can break or seal a deal, especially in today's world, where users often complain that their smartphone struggles to last a single day. If the anonymous source's tip-off is an honest one, the Galaxy Note 3 could become a real seller based on battery alone.
Meanwhile, SamMobile has uncovered a DLNA certification purportedly confirming that the Galaxy Note 3 will ship with Android 4.3 Jelly Bean.
Last week, Samsung distributed invitations for a special event in Berlin on 4 September, where the world expects the launch of the Galaxy Note 3.
Rumoured specs have already emerged, with the gossipers saying that the phablet will feature a 5.7in full HD 1,920 x 1,080 display, a 13-megapixel rear camera, a Snapdragon 800 processor and 3GB of RAM.
However, alternative reports claim the Note 3 will come in three sizes - 5.7in, 5.99in and 6.3in - carrying the new Exynos 5 Octa processor.
Also hot on the lips of the world's technology experts are whispers of a big Galaxy Gear smart watch reveal.
A freshly-discovered trademark application suggests the wrist-bound device will feature a 1.6in screen and the ability to read messages and emails.
