I'm posting this thread because my experiences with my S7 Slim's battery performance is very disappointing in a way. As far as we speak of continuous load performace, nothing strange. The battery lasts a decent 3-12 hours performance, depending on usage. But why the hell is it drains after 2 days in soft-off I've expected at least 6-7 days sleep performance. 2 days is ridiculous Only using wi-fi (even no sim card inserted) and is switched off in sleep mode. Auto sync switched off also... Anyone has any idea how to extend standby performance?
