[iMore Question]

"Never" is the only other option, but I "never" remember to turn it off, and then my phone gets hot and the battery dies.

The choices are the ones you see- 1,2,3.4 and 5 along with never. Personally I keep mine at a minute and it serves me well

I only need it occasionally, like when I'm shopping and I need the screen to stay open for longer than 5 minutes but not usually more than 15. With "never," I end up forgetting to change it back to 1 or 3, and then, the next time I notice, the battery's at 10 percent and I'm rushing to plug in the charger. But thanks for responding!
