Good expansibility is critical for traditional computer. Essentially, it's like a customized box that you could easily add memory and hard drive to achieve more smooth running speed and larger storage space. However, the personal smart mobile device revolution initiated by Apple has changed everything.
Apple's iPhone, iPad and iPod are more like seal boxes compared to conventional computer. The capacity is fixed and you couldn't upgrade. Quick scan Apple's current product line, though it's going to the same direction, apparently there are more limitation for iOS device than Mac product. Although MacBook Air doesn't have much storage space, you can still add external hard drive, which iOS device can't achieve. iOS device doesn't have a standard USB port, and not even with an available file manager. The basic philosophy of iOS device is to store in itself or in iCloud. Hence if you need larger space, think about the capacity before purchase.

However, even though you have brought the largest capacity one, you still find that it's not enough. With the developing technology like retina screen, increase volume of the apps, HD videos, high resolution photos and all sorts of digital magazines, the entry level 16GB can no longer meet user's need. Then it's quite necessary to clear the system adequately.
Same as usual, before any major operation, we suggest you to backup your iOS device. Even though you have an iCloud backup, sometimes it's better to keep one backup in your computer local since it could fast backup and recover the app data despite you have deleted them in your device. You could use iTunes to sync music to Mac, USB to transfer videos and photos to iPhoto in Mac. So those are general ideas, now let's see the details.

How to Manage Storage of All iOS Device

1. Test device capacity from desktop version iTunes.

Desktop iTunes is not the only way to check device storage capacity but it's practical. After connecting iOS device to iTunes in PC or Mac via USB wire or WiFi, you will see an intuitive icon below, demonstrating the detailed storage info in different colors, representing music, photos, videos, apps, books and others. You will have to think about releasing some space if the storage volume is not enough. The bulk photos and music which have been synced before could be deleted via desktop iTunes by un-ticking the related categories. Click sync and the content will be erased.
Sometimes you may find that "others" occupies most of the storage space but you have no idea what are they. Normally those are data of the third-party apps like offline video files from online video software, or app that you have failed to update. At this time you may need to enter relevant app to delete the content, or again sync so that the fail-to-update app will be removed. If it still doesn't work then you better recover the system from your PC local backup.

2. Check the app size
Some iOS apps size are huge like mega 3D games could reach to GB. The app size which shows in AppStore is before decompressed, once you decompress and install it may takes up more space. You can check the actual app size in "Applications" in desktop version iTunes and remove the extra large apps.

3. Check app data

Go to "Settings" - "Ggeneral" - "Usage", you will be able to see all the app data here. Clear some according to your need. Some apps themselves are not big but after you use for a while it will become larger. For instant, social network app, online videos and music, the more you use the more cache file will accumulate. Then you can enter the apps and search "Delete the Cache" or manually remove some auto-downloaded content. If there's no similar option then you may need to delete the app and install again.

4. Back-up Content of Apps
If you don't use an app or play a game temporarily but you may need it again someday. Then you can install some third-party managing softwares in your PC or Mac and backup the app content to your computer. Now you can delete them in your iOS device. You could access to the record before deletion by copying content to the relevant files once you need to use again.

5. Apply "Deadline" file managing method
If you like to download mass apps but don't remember which one you don't use that much, then you may try a "deadline" managing mode. Create a folder and name it with the date like "07-2013", then you can put the apps and data that you don't use inside. When you need to use again then you can recover them back to the iOS device. Otherwise if you don't use anymore you can delete them all.
We have to mention about message and the iMessage attachment when discussing about storage space. Deleting attachment various in regard of different iOS version. For example, if you are an iOS 6.1 user receives a message with pic in iMessage, even though you have deleted the pic in iMessage, the pic will still be in your device and you can find it through file path. Even if you try to reboot the pic is still there. However, in iOS 6.1, if you delete the image in iMessage you won't be able to find it in your device. Therefore, the older version iOS device will encounter storage space problem after being used for long time.
