OK, if you're like me, you know it's a pain in the ass when you're iphone starts to say that you're almost out of space. I recently learned this trick so I'm sharing with you 😁. Let's go!!!
Step 1: Go to Settings-->General-->About This step is just to check your available memory.
Step 2: next to "Available" you should be able to see how much memory you have left.
Step 3: Go to the iTunes Store and rent a movie. The recommended is "The Lord of the Rings: The Two Towers" since this movie needs like 6GB to be able to work.
Step 4: You will get the message below. Click "ok" and repeat "Step 3". Keep doing this until it finally ask you for your password. Then just click "cancel". You can keep going if you like and just continue to click "cancel" but this is usually where I stop.
Step 5: This isn't really a step but more of a confirmation of your success. This is how much space I got freed after doing it three times.
Warning: I have an iPhone 5s and this trick works on mine. My sister has an iPhone 6 and I tried this same trick but it didn't seem to work on hers. So good luck to you guys and let me know how it works for you!!! 😁
