For smartphone users, especially iPhone, iPad or iPod touch storage media is very important that a smartphone can run normally. Sometimes if the remaining space is up then your smartphone will run slower, and the application does not run normally. And how can you Make smart decisions about what to keep and what to delete? Follow Reviews These few simple steps, and you’ll be on your way to a less overloaded, more organized iPhone or iPad. taken from http://www.pcmag.com some tips
1. Check Your Total Usage
Go to Settings > General > Storage & iCloud Usage.
At the very top, you’ll see Used and Available space. Those fields refer to the space on your iPhone or iPad. Below them, you’ll see your iCloud space. For the purpose of this article, however, we’ll just focus on local storage, the top numbers.
You don’t need to understand these numbers deeply, and there are no hard and fast rules about how much space you need to leave free on your iPhone$649.00 at Apple Store or iPad$599.00 at Apple Store or iPod touch$199.00 at Apple Store. If you simply want to have enough free space so that you can take new photos and install new apps without worrying about hitting an obstacle, give yourself at least 1GB of free space (1GB=1,024MB). I’m more comfortable leaving at least 2GB available.
Note that when you add your available space and the used space, they won’t add up to the total size of your phone (e.g., a 16GB iPhone may appear to have only about 12.3GB total space) because it doesn’t include the space being used by the operating system.
2. Analyze Which Apps Are Taking the Most Space
Tap on Manage Storage. Here you’ll see a list of all your apps, in order of how much space they consume.
Select any app, and a new page shows the usage into two parts: the amount of space the app itself uses (in light gray at the top) and the space used by the app’s data and documents.
For example, my favorite podcasting app Downcast$2.99 at iTunes Store takes up 622MB total: 17.1MB for the app and 605MB for documents and data.
Sometimes, this information helps you see that it’s not the app that takes up so much space, but rather what you store in it. In my case, the Downcast app is listed first when I go to the Manage Storage page, meaning it is the app that takes up the most space of all my apps, so I know I can make big gains by getting rid of any excess data in it. And I have some options. I could listen to the podcasts that are saved in the app and delete them afterward. Or I could change my settings in the app so that new podcasts only download to my phone when I want to play them. Or I could change the settings to only stream podcasts with a video component and never download them.
3. Check Your Photo and Video Use
A lot of people find that the Photos & Camera app takes up a lot more space than they realized, so let’s deal with that app directly.
When you tap on that app to see how much space it uses, you’ll see both Photo Library and Shared Photo Stream.
Right now, just focus on Photo Library, as that’s the space being used locally on your iPhone or iPad.
If you have more than 1GB here, you should consider copying photos and videos to another storage space so that you can delete them from your iPhone and free up a lot of space. In my opinion, one of the easiest ways to do it is to use Dropbox to offload your iPhone photos. You can use any cloud-based syncing and storage service you like, such as Box, SugarSync, etc. It doesn’t have to be Dropbox per se, although ideally you want the service to have a mobile upload feature in its iPhone app, as Dropbox does.
You can find complete instructions for transferring photos and videos off your iPhone or iPad and into Dropbox in the article linked above, but to summarize, you’ll turn on the Camera Upload feature and let it run. When it’s finished, log into the Dropbox app and verify that you can find and open your images. Then, delete them from the Photo app. Finally, open the Photos app, go to Albums, and select Recently Deleted. Tap Select, and then at the bottom tap Delete All. If you skip that last step, you won’t free up any space for a month, as your iOS device will hang onto deleted photos for 30 days, just in case you change your mind about deleting them. When you use the Dropbox upload tool, you don’t have to worry about it because you’ve already made copies of the photos and saved them to Dropbox.
Other apps that often take up a lot of space because of their data include music players, podcast players, Voice Memos, and office apps. You probably want to keep the app itself, but you might be able to free up space by deleting files that are no longer relevant.
To delete documents and data, you have to open the app where they’re contained and remove them there. In other words, you can’t delete them from the iPhone or iPad Settings area.
4. Target Apps You Don’t Use
Go back to the Manage Storage page. Scroll through the list of apps and look for apps you don’t use. It’s much easier to find apps you no longer need here, where they’re in a neat list, than on your home screens, where they are likely to be scattered across several pages and bunched into folders. (See also my tips for how to organize your iPhone or iPad apps among the home screens.)
If you find apps you don’t need or don’t use, or which you only use in specific contexts, such as only using travel apps while traveling, consider deleting them. Any app you’ve purchased in the past is always available for you to download again at no extra charge. Apple keeps track of apps you’ve purchased in the past so that you don’t end up paying for them twice.
To delete apps, go to your iPhone or iPad’s home screen and press and hold any app. You’ll see all the apps shake on screen. A small X appears on each icon. Press the X, and confirm to delete.
When you’re done, press the home button.
5. Remove Unwanted Music Tracks and Albums
Multimedia, such as audio tracks and videos, takes up a lot of space. There are two ways to delete audio files and videos.
From Settings Go to Settings > General > Storage & iCloud Usage > Manage Storage.
Scroll down the Music app and tap it. The next screen summarizes all the songs and albums you have stored locally.
Clean out all the tracks in any album by swiping it right to left. You can also use the Edit button (top right) to delete multiple tracks and albums in one shot. Both of these actions delete all the files associated with the entry or album.
From Within the App Open the Music app. Go to Artists > Only Downloaded Music. Toggle that button on. Now you’ll only see music that’s stored locally and taking up space.
Delete track by track, album by album, and so forth, by tapping the song or album and hitting Delete. If you notice a lot of duplicate tracks from music you put on your iPhone or iPad from iTunes, you’re better off cleaning them up in iTunes rather than on your mobile device. You can get help from software that specifically handles deduping in iTunes, such as Leawo Tunes Cleaner.
6. Empty Safari’s Cache
One final smidgen of junk to wipe off your iPhone or iPad is the cache for the Safari Web browser or other mobile Web browsers you use.
For Safari, go to Settings > Safari. Tap Clear History and Website Data.
Other mobile browsers may have slightly different instructions for dumping the cache. Try looking in the app’s settings if you can’t find the option in the iOS Settings.
