If you maxed out your performance and data usage, all sensors on along with excessive app usage and and display set at max brightness. That's possible given all or most of the aforementioned conditions are present.
same problem. even with the power saving mode on , I got only 17hours and it's when I had 100% battery life. but if I use wifi and watch YouTube or music n check camera for 2 hours or less. it's already less than 40%
