Hello, I have tested this now atleast 10 times over. All stock firmwars, marshmellow, nougat. no root. Some firmwares have the dreaded overnight battery drain, and some do not.
Taiwan and NOBA region firmwars both drain battery overnight. For example, go to bed in the evening with 100% battery, and wake up in the morning and find you phone with only mid to low 90's battery remaining.
Hong Kong and Australia region firmsware - these both hold their charge overnight. 100% in the evening, and 100% when you wake up in the morning.
I have tested this many time - and this test is 100% repeatable and reproducable. You can test it yourself and get the same result. Before posting this I have checked, rechecked and tripple checked, and this is more definitly the case.
One thing I have notived is that both Taiwan and NOBA firmwares with the battery drain, both have an app called Emergency Alerts, which is used to give early notification of Earthquakes and other disasters. While HK and AU with no battery drain, do not have this app. Maybe its coincidence.
