Samsung Galaxy Note 6 could have curved screen and huge battery.

With the Samsung Galaxy S7 and S7 Edge launched and in the running for best Android smartphone of the year, all eyes are now on Samsung's other flagship phone: the Galaxy Note.

Samsung's next Galaxy Note, presumably called the Galaxy Note 6, won't arrive until this summer, but we're already hearing some chatter about it.

According to SamMobile, which has a reliable track record when it comes to Samsung-related rumors, Samsung is testing two variants of the Galaxy Note 6, one with a curved screen and one with a flat screen — both have Quad HD (2,560 x 1,440) resolution.

But unlike last year, where the Korean electronics giant launched the Galaxy Note 5 and Galaxy S6 Edge+, both with identical tech specs, with the only differences being the Note 5's stylus and flat screen and the S6 Edge+'s dual curved glass sides, there will only be one model this year.

That makes sense since the S7 has a 5.1-inch screen, the S7 Edge has a 5.5-inch screen and the Galaxy Note will reportedly have a 5.8-inch screen (0.1 inches larger than the Galaxy Note's 5.7-inch, if you care).

A larger battery is also another feature Samsung is looking to include in the Galaxy Note 6. The report claims a 4,000 milliamp-hour (mAh) battery. The Galaxy Note 5 only had a 3,220 mAh battery.

Other rumored specs include both the Qualcomm Snapdragon 823 processor and Exynos 8890 chip, 6GB of RAM and 32GB of internal storage. We wouldn't be surprised if Samsung brought over the S7/S7 Edge's microSD card, water-resistance and fast wireless charging to the Note 6, too.

No mention of what kind of camera the Galaxy Note 6 will sport, but it'll likely be the same 12-megapixel rear shooter and 5-megapixel front shooter (both with f/1.8 aperture for killer low-light performance) from the Galaxy S7/S7 Edge, along with the same ultra-fast dual pixel autofocus system.

The phone is expected to be one of the first to run Android N, the next version of Google's mobile operating system.

We won't know for sure until Samsung announces it, but it all sounds like a lot to get excited for if you're looking to upgrade to the next Note.
