[Q] android system taking half of battery? topic

I realized that android system takes up almost half of my battery in comparison with screen time? What's draining it?

Just lost half of the pictures moving from on-board to SD topic

It is running CM 10.2.0-skyrocket and I just wanted to make some room on the phone for my senior mom by moving pictures to SD card and to my surprise half the pictures, if not more, is just a pixelized mess or just gray box.

Is there a way to recover the original pictures on-board storage?
