The site reckons the Note 6 will come equipped with a monster 4,000mAh battery, a significant jump from the 3,000mAh one that was inside the Galaxy Note 5. This device could be one that runs and runs.
GSM Helpdesk's sources also reckon there's the chance of a curved screen for the Note 6, although apparently Samsung hasn't quite decided on that yet - it certainly has the know-how from its Edge line of phones.
Note 6 ex-specs-tations
Apparently the next Note will ship with a 5.8-inch, QHD 2560 x 1440 pixel screen, a fingerprint scanner and a 12-megapixel camera similar to the ones debuted in the S7 and the S7 Edge at MWC 2016 earlier this year.
That would seem to contradict earlier rumours of a brand new, top of the line camera for the Galaxy Note 6. We've also been led to believe that Samsung is planning to make the upcoming phablet waterproof as well.
GSM Helpdesk isn't the most prolific source when it comes to accurate insider info, though it did get the specs right in advance for the HTC 10. We're expecting to see the Galaxy Note 6 sometime in August or September, so there's quite some time to wait yet.
