Note 8 battery that is 5.71% SMALLER (NEGATIVE impact)
2GB additional RAM (NEGATIVE impact)
Screen TINT bit bigger (NEGATIVE impact)
IDENTICAL SoC with NO performance tweaks/boosts (neutral impact)
You REALLY expect someone to believe the comparison between the 8+ and Note8 is accurate?
How many runtime tests were run? Was a script used to achieve identical usage pattern? What temp were the devices at? How many apps were installed and setup? Were the phones tested factory reset/new out of the box? So MANY factors the results you offer are TBH laughable. It is PHYSICALLY impossible for the Note8 to achieve a longer runtime than the 8+. Pretty sure physics says so. Oh and chemistry too.
