Tips to extend your battery usage time in Samsung Galaxy mobile device

Last Update Date : Mar 23. 2018

Samsung Mobile Devices such as S8/S8+, Note8, A8/A8+, S9/S9+ provides various ways to increase battery usage time. During the initial period (approximately 3 days) after the purchase, the battery usage time may be shorter because App power monitor feature and Optimization of battery usage feature do not work properly.
