Re: iPad mini battery drain!
Hi there are are few things that may cause the battery to drain.
1. You may have apps running in the background that is constantly needing CPU power and thus your battery drains.
2. Any CPU intensive apps will likely to use more battery power.
3. You may have been in a poor reception area where it's constantly checking for signals.
Here is what you can do:
Double tap the home button (or 4 finger swipe up) to bring up the Recently Used Tray bar, hold the apps for 3 seconds until they shake. Then tap on the Red circle with the " - " to force close the apps.
If you are in a low reception area, I recommend turning of your cellular data by putting it in airplane mode to save battery.
Here is one suggestion that most people would say:
Calibrate the battery meter simply by using your ipad and draining it down to 10% to 5%. Turn off the device, then plug in to charge it. This should calibrate the battery meter.
Also go to Settings > General > Reset > Reset all Settings (this will not erase any of your data at all, only resets your settings).
