Ipad 2 which is not even 6 months old is losing battery charge quickly.
The charger was bought at a local grocery store.
It does charge to 100% but I find that it loses charge a lot quicker.
I have looked at the different possibilities of what could cause this
Even though I haven't changed any settings I have double checked and made changes to data roaming, apps etc
????
Use the Settings app to determine what apps or processes are using the most battery.
Settings > General > Usage > Battery Usage
Wait a bit until the apps populate and display the amount of battery they are consuming. Look for anything suspicious.
Sometimes an app is updated and the update adds new features that use more battery or change settings. Once you know which apps are causing your battery drain you can take steps to correct the situation.
As far as non-Apple charger: I use a charger in a wall outlet that is definitely not made by Apple. It provides the correct amount of power for iPhones but not for an iPad Air. The iPad often displays a Not Charging message but the iPad is in fact charging albeit quite slowly. I always use Apple brand cables.
