Regarding this, can I leave my iPad screen on all the time?
No, it is not bad. The Retina display is made of a burning oxide gas. It's not like a Plasma or LED tv where images can get burned into the screen. I just suggest shutting it down at night to let the device “breathe”.
Beside above, what happens if you leave your iPad on all night? There is no “memory effect” like older Nickel Cadmium batteries, so you can charge your iPad anytime you want and even leave it on a charger overnight. The battery will also charge very rapidly, to about 80% in a few hours, while the last 20% is more of a trickle charge and takes longer.
Then, how long can you leave iPad screen on?
They are typically going up to 13 hours a day, and plugged in 24/7 as well. An iPad used like this will last for years.” So there you have it, leaving an iPad running for 13 – 14 hours per day, as long as it's plugged in and maintained, should last for years and years!
Why is my iPad screen not turning off?
Go to Settings > General > Auto-Lock and set the time to something other than Never. It is set for 2 minutes but it does not ever shut off or sleep. Try a reset: Simultaneously hold down the Home and On buttons until the iPad shuts down. Ignore the off slider if it appears.
