It is a MYTH that 'closing out' of all of your iPad applications will make the battery last longer or make your iPad run faster. The iPad will only 'run' what is currently up on your screen, whether that be one app or two (with split screen)
 | Closing out of all of your apps may create an unintended consequence. Many apps require login with a Google or Microsoft account. Once you are logged in to any ‘Google’ app, you will not need a password for any other Google app. IF you close out of every app, you will likely need to log back into them later, an extra step that may not be necessary. This includes popular apps such as SeeSaw or ClassLink |
So what WILL affect my iPad battery? | |
 I rarely ever turn off my iPad. It will only get restarted about every month or so when there is an update. I use it every day and plug it in to charge every night. | Check the sleep settings on your iPad.This may be found in Settings->Display & Brightness -> Auto-Lock If you use your iPad as a document camera, you will likely want to delay the time before it goes to sleep, perhaps changing it to 10 or 15 minutes. Adjust as desired. When you close the cover, the iPad display will go to sleep, too. |
 | Use the correct charger for your iPad. Most phone chargers are rated at 2 watts, including what's likely in your car. You may be able to charge your phone with a 3 or 4 watt charger, but you do need to be careful. Putting too much charge too fast may cause heat issues with your phone and shorten its life. iPad chargers are rated at 12 watts. It's fine if you use a charger with less wattage. It will not hurt anything. However, it may take much longer to charge up. If the display is not 'asleep' then you may be using up the battery faster than it is charging. |
