To avoid shortening the life of the rechargeable battery in your iPad, take these steps. Charge or deplete the battery until it has a 50 percent charge. Then turn off your iPad:
- Press and hold the Sleep/Wake button until the slider appears.
- Drag the slider to turn off your iPad completely.
Store your iPad in a cool, moisture-free environment that is less than 30° C (90° F).
You can store an iPad mini (7.9-inch display) for as long as 6 months without recharging. You can store other iPad models for as long as a year without recharging.
When you remove your iPad from long-term storage, you might need to charge it with the original adapter for up to 20 minutes before you can use it. If you store many devices, store each one for the shortest possible time. When you remove an iPad from storage, make sure that you remove the one that's been stored the longest.
