The Samsung Galaxy Note9 may have to launch early, but there is still time for some improvements. This is based on rumors coming out of Weibo from normally reliable leaksters, but we'd wait on some official sources before we're sure (the Brazilians love leaking battery capacities).
The new Note may be slightly larger at 6.4” and of the same aspect ratio. It’s a small change, but it will widen the gap between the Galaxy S9+ and Note9. Whether there will be a fingerprint reader beneath this display is a whole different matter and we’ve seen many contradicting rumors.
Anyway, the increase in battery size will be more substantial, growing from the 3,300 mAh of the outgoing model to 3,850 mAh or even 4,000 mAh. The Note9 will use the same chipsets as the S9 duo (we already saw the Snapdragon 845 version do Geekbench), but the larger battery should offer an upgrade to endurance.
