I have an iPad 2 with 16GB. As we all know with the iOS installed, we only left with 13.4GB for all our stuff.
Mine has been at the critical point of 1GB lately, so I started deleting stuff on the iPad to reclaim some of the space. I only have apps on it now, I stream my music from my iTunes library, and not really crazy to have movies and watch them on my iPad.
It has been 3 years since I bought it, I figured last week it was time to reset it to factory settings and restore my backup to give it a deep cleaning, like how we are supposed to with our laptop every year to cure performance issues.
So I did it last week. Make sure you backup your iPad on the computer before doing anything!!!! It took about an hour, and you know what, now I have 9.4GB of empty space, that’s almost 900% gain.I was astonished.
I think when you deleted apps on the iPad, it didn’t really uninstall the entire app, so some stuff were left behind…so this is the only way to clean it up, get space back, and improve performance: it had been freezing many times before I did this.
I am sure you know how to do this, anyway the steps are:
1) connect iPad with USB cable with iTunes on ( I wouldn’t do this wireless)
2) select device and pick iPad. On summary page, Backup and then Reset to Factory Settings.
3) Follow steps on screen after iPad is reset, and select “backup-date” to restore
Everything will be exactly before the reset including your wallpaper! I am going to do same with my iPhone now.
