using note 8 with one ui. the battery drain in malaysia is definitely faster than in oversea. i find malaysia telco got very lousy 4G connection. The phone have to use more juice to locate 4G signal. When in HK or Japan same 4G connection, but battery drain way slower/

yes i spend 50% every month oversea, i know our 4G signal is weak in malaysia (at least at my area) so our phone use more juice to locate the signal.

my usually hangout area is Maxis line in ampang area.
