c7 doesnt have that num of camera module as note 10 have got. Plus u get fhd+ display which consume alot of battery.C7 doesnt have fhd display.U have got charging spen in note 10 series which also consumes some battery..
thanks brother for helping comments, but c7 also has 1080p display, second I don't often use Spen. Problem with Note 10 lite is that despite in sleeping mode it continue to consume battery at a faster rate. I think that's Exynos issue people often discuss on blogs.
