I use S7 Edge (SM-G935FD). After May security patch, my battery drains very fast. According to my use, I'd get around 6.5/7 hours of screen usage. Now I get around 5.5/6 hours of on-screen usage. Updates are for removing the lags Samsung not receiving the lags. Please suggest something or else give us an update that improves this. Very unhappy Samsung☹
