Cleaning. Clean iPad immediately if it comes in contact with anything that may cause stains or other damage—for example, dirt or sand, ink, makeup, soap, detergent, acids or acidic foods, and lotions. To clean:
Disconnect all cables, then do one of the following to turn off iPad:
On an iPad with a Home button: Press and hold the top button until the slider appears, then drag the slider.
On other iPad models: Simultaneously press and hold the top button and either volume button until the sliders appear, then drag the top slider.
All models: Go to Settings
> General> Shut Down, then drag the slider.
Use a soft, slightly damp, lint-free cloth—for example, a lens cloth.
Avoid getting moisture in openings.
Don’t use cleaning products or compressed air.
> General> Shut Down, then drag the slider.The front of iPad is made of glass with a fingerprint-resistant oleophobic (oil-repellant) coating. This coating wears over time with normal usage. Cleaning products and abrasive materials will further diminish the coating and may scratch the glass.
Using connectors, ports, and buttons. Never force a connector into a port or apply excessive pressure to a button, because this may cause damage that is not covered under the warranty. If the connector and port don’t join with reasonable ease, they probably don’t match. Check for obstructions and make sure that the connector matches the port and that you have positioned the connector correctly in relation to the port.
Lightning to USB Cable. (models with a Lightning connector) Discoloration of the Lightning connector after regular use is normal. Dirt, debris, and exposure to moisture may cause discoloration. If your Lightning cable or connector become warm during use or your iPad won’t charge or sync, disconnect it from your computer or power adapter and clean the Lightning connector with a soft, dry, lint-free cloth. Do not use liquids or cleaning products when cleaning the Lightning connector.
Lightning to USB Cable or USB-C Charge Cable. (depending on model) Certain usage patterns can contribute to the fraying or breaking of cables. The included cable, like any other metal wire or cable, is subject to becoming weak or brittle if repeatedly bent in the same spot. Aim for gentle curves instead of angles in the cable. Regularly inspect the cable and connector for any kinks, breaks, bends, or other damage. Should you find any such damage, discontinue use of the cable.
Operating temperature. iPad is designed to work in ambient temperatures between 32° and 95°F (0° and 35°C) and stored in temperatures between -4° and 113°F (-20° and 45°C). iPad can be damaged and battery life shortened if stored or operated outside of these temperature ranges. Avoid exposing iPad to dramatic changes in temperature or humidity. When you’re using iPad or charging the battery, it is normal for iPad to get warm.
If the interior temperature of iPad exceeds normal operating temperatures (for example, in a hot car or in direct sunlight for extended periods of time), you may experience the following as it attempts to regulate its temperature:
iPad stops charging.
The screen dims.
A temperature warning screen appears.
Some apps may close.
Important: You may not be able to use iPad while the temperature warning screen is displayed. If iPad can’t regulate its internal temperature, it goes into deep sleep mode until it cools. Move iPad to a cooler location out of direct sunlight and wait a few minutes before trying to use iPad again.
See the Apple Support article Keeping iPhone, iPad, and iPodtouch within acceptable operating temperatures.
