How to Use the Usage Settings on Your iPad mini
Need to know what’s hogging all that space? The About setting gives you a lot of information about your iPad mini. But after you back out of About and return to the main General settings, you can find other settings for statistics on iPad usage:
Battery: You almost always see a little battery meter in the upper-right corner of the screen, except for certain instances, such as when you watch videos and the top bar disappears. If you also want to see your battery life presented in percentage terms, make sure that the Battery Percentage setting is on.
You can also see how much usage and standby time you’ve consumed since your last full charge. Usage (by percentage of battery used) can be displayed by app for the past 24 hours or the past 7 days.
iCloud: This setting shows the amount of total and available storage. Tap Manage Storage to, well, manage your iCloud storage, taking note of all your iOS backups. If need be, you can buy more storage. Tap Change Storage Plan to get started.
You can pay 99¢ a month for 200GB, $3.99 a month for 200GB, or $9.99 a month for 500GB. Need a full terabyte each month? That’ll set you back $19.99 monthly. You can also downgrade to a free 5GB plan.
Storage (for the device): Check out which apps on your iPad are hogging the most storage and delete those (from here) that you’re no longer using.
