This is not a drill, It works! I didn’t believe it when I heard about it but I myself cleared 3.5GB from my phone! and that was all Cache!! iPhone storage is always at a premium, especially if you have an entry-level model with just 16GB.
You’ve probably heard all the usual “free up space” tips and mostly are repetitive and complete crap, but I’m willing to BET you haven’t heard this one. It is not a tip but it is black magic for anyone who is always short on iPhone space. You will love me after that.
Your iPhone doesn’t need to be jailbroken, and this doesn’t void your warranty or involve any kind of risk. Try it, and see what happens.
Here’s what you have to do:
Step 1: Tap the Settings app and then tap General > About to see how much storage is available. Note that as the “before” number.
Step 2: Open the iTunes Store app, head to movies, and find any really large title. “The Lord of the Rings: The Two Towers” is a good choice at 6.83GB. (You just need to find a movie that requires more space to download than you have available on your phone.) Tap the Rent button twice, keeping in mind you won’t actually end up renting it (and therefore won’t be charged anything).
Step 3: Once you see the message that there’s not enough space available to download your rental, tap Settings. Then navigate back to General > About and you should see a couple hundred megabytes’ worth of additional available storage — possibly even more. And just like that, an extra 400B.
Step 4: Repeat the process! (That is, go back to the iTunes Store app and try renting the movie again.) Each time, you should wind up with another chunk of freed-up storage. Keep going until you either have too much free space (meaning you’d actually be able to download the movie) or the available space stops rising.
It’s not immediately clear why this works, but it does. I just tested it on an iPhone 6 with the latest iOS and now I have 3 more GBs!!.
Repeated attempts yielded no more space. But if you check the Reddit thread devoted to this topic, you’ll see that many users tacked on hundreds of megabytes numerous times, and some were able to reclaim gigabytes of space. The best news of all: There doesn’t appear to be a downside to this. It’s not like iOS is secretly wiping out your photos or something. Instead, it’s probably clearing out caches that shouldn’t be full in the first place — suggesting this is a storage issue Apple should investigate and in next update give us a simple button to clear up all the caches and junk files it creates on our iPhones and eat up all the valuable space. Now, give it a try and if you succeed don’t forget to comment your results here! and share it with your friends.
