Samsung's anticipated unpacking event is about to go live in a few hours, where the Korean tech giant will unveil Galaxy Note 5 and Galaxy S6 Edge Plus smartphones. But the rumour mill has been buzzing about the handsets' features. Popular mobile tipster @evleaks revealed the battery details of the two models, which were missing in the past rumours. According to @evleaks, both handsets will sport 3,000mAh batteries offering up to 21 hours of talk time.

For the past couple of weeks, rumours about the two upcoming phablets have been quite frequent. Even before Samsung released the new Galaxy smartphones, the entire spec-sheet was out and the revelation about the battery units completes the list.

At the same time, it is disappointing to see the new Galaxy Note featuring a smaller battery unit than its predecessor, which packs a 3,220mAh unit.

The reason behind using a smaller battery is known only to Samsung, but we guess the new handsets will have better optimisation to run longer than previous Galaxy Note models.

According to a round-up report by IBTimes India, Samsung Galaxy Note 5 is expected to arrive with a 5.7-inch Quad HD Super AMOLED display with 2560 x 1440 pixel screen, 515ppi and powered with the company's home-grown Exynbos 7420 chipset. The handset will also feature a 4GB LPDDR4 RAM, a step up from Samsung's flagship Galaxy S6 smartphone.

In addition, the Galaxy Note 5 will pack industry's leading camera sensors, borrowing from the Galaxy S6. A 16-megapixel rear-facing camera with Optical Image Stabilisation, f/1.9 aperture complete with camera modes such as High Clear Zoom, Selective Focus and IR Detect White Balance are said to power Galaxy Note 5. On the front side of the device will be a 5-megapixel shooter with Auto Real-Time HDR mode.

Being the company's latest flagship device, it is evident the Galaxy Note 5 will be powered by Android 5.1.1 Lollipop OS. Additional features such as fingerprint scanner, advanced S-Pen stylus, wireless charging support and a USB Type-C port are also in the books.

As for Galaxy S6 Edge Plus, the features are expected to be the same as Galaxy Note 5 with some visual differences. The Quad HD display in the Galaxy S6 Edge Plus will measure 5.5 inches diagonally with higher pixel density of 534ppi and dual-sided curved screen.

Samsung will officially launch the Galaxy Note 5 and Galaxy S6 Edge Plus at the unpacking event, which will begin at 11am (EDT). Fans in India can live stream the event directly from the company's website starting 8:30pm Thursday night.
