What Happens If You Dont Use Your Ipad For A Long Time. The most likely. In fact if you dont regularly use your iPad you should perform a complete charge cycle once a month where you fully discharge the battery then charge it up to 100.
But if your kids technology use is not working out for your family I strongly encourage you to have a family meeting talk about the issues. Alternatively perform a hard restart by pressing and holding both the HOME button AND the POWERSLEEPWAKE button until the Apple logo appears. Dont overcharge your mobile phone.
The most likely.
It depends on what kinds of setting you choose to operate. While you need apps to make your iPad fun those apps dont need to spend the day polling for updates and wasting your battery. If you backed up your iPad you can restore your data and settings after restoring your iPad. If you dont plan to use your iPad for a long time say a few months store it with about a 50 charge for best performance.
