I feel like the battery drains very quickly, something like 15% to 25% a day. I read many hours a day (more like a night), and I've noticed that I tend to set the light higher than before - an effect of the screen quality and the ease of the finger sliding: with bright lights outside, it usually ends at 100%, with lower electric light, often around 50%, at the lowest around 20%.
I have no cover and no SD card.
Do you think I should ask for an exchange? I don't measure how many hours I read, but I could at least try to monitor my night-time reading.
