Why I always find samsung users crying?? some cry over not getting latest updates and others who got update crying for battery usage. Why samsung why樂

got this 218 MB update yesterday. 6bettery usage still good. watched videos on facebook and twitter whole night at 20% screen brightness and it gave me almost 7+ hour screen on time. but the standby time is worst

Got this july 2018 security update... after updating two things so far noticed. Number 1 is battery usage much much improved getting 2 and half hour screen on time for only 25% of battery drain. And the second thing is recovery error has been resolve...
