Apple for 16GB iPhone users left an egg ...-iPhone,16GB,iTunes-IT information
16GB, also known as beggar iPhone users have a common secret: every once in a while to try to clean up the storage space, delete infrequently used app. Delete does not move when inevitably regret not spending hundreds of dollars to buy 64GB. Optimists will comfort themselves, often clean up mobile phones help to develop "broken homes" good habits, recognizing the truly important to their (app) is.
Unexpectedly, users of Apple's iPhone version actually gave the beggar a huge egg. Strictly speaking, eggs are for all iPhone users, but beggars user needs, are more likely to eat the egg--believe it or not, do not delete any app, any photo or video, iPhone they would go find a way to help you make "massive" usable capacity?
Egg usage is like this: suppose the iPhone only 1GB of usable capacity, then in iTunes choose a film that is larger than the 10GB Store purchase or rent (not really), the system will remind "not enough free storage space to download." Magic moment comes when you go back to iPhone usable, you will find that it is likely to become 2GB. Not yet, repeat it back to the iTunes Store, you will find the iPhone has the potential to become 3GB of usable capacity. Has been doing this forever, iPhone will continue to find ways to continue to make room, until you can do about it. Do pay attention here, find a space a lot of film, or if the iPhone really make enough space will really start the download, this time on the bodice.
Next, look at the beggar hot iPhone 6 usable capacity from 537MB to the 3.3GB instance:
1, to view the current available capacity, the path "Settings--General with iCloud-storage space". Here is 537MB.
2, open the iTunes Store, choose a bulk film. Selected here is let the bullets fly, 1080p, HD 4.97GB, enough for this phone.
3 select "$ 1.00 purchase", wait for the popup "unable to download" notice.
4, go to view available capacity has become 1.6GB (wow, amazing, quickly transferred to other beggars).
2~3 5, repeat the above steps, 2.4 GB of available capacity (does not believe them).
2~3 6, repeat the above steps, becomes a 3.2 GB of available capacity (excited).
2~3 7, repeat the above steps, 3.3 GB of available capacity (there's hope).
2~3 8, then repeat the above steps, find usable capacity is 3.3 GB (Apple).
9, well, that's it. We take a look at what Apple did, note the PayPal icon on the "cleaning ...".
In other words, Apple to help clear it considered less important content, for users with no apparent effect. In PayPal, for example, the bloated app normally occupies more space than 500MB,iPhone in order to hold the movie, select it, and then killed some of its old cache files automatically, so that it takes up space back to the normal state of about 150 MB. If you are careful enough, you will find when you reopen the PayPal, avatar will try to reload, album photo quality are also compressed.
This egg is found on the mackungfu.org, it is said that it had been there for a long time. If the time you read this article, Apple has fixed the "loophole", please don't blame us. Who told you you're poor!

苹果为16GB容量iPhone用户留了一枚彩蛋… - iPhone,16GB,iTunes - IT资讯
16GB版，也叫乞丐版iPhone用户有个共同的秘密：每隔一段时间就要想办法清理手机存储空间，删掉那些不常用的app。实在删不动的时候，难免后悔没多花几百块钱买64GB的。乐观派则会安慰自己，常常清理手机有助于养成“断舍离”的好习惯，认清真正对自己而言重要的（app）是什么。
万万没想到，苹果实际上给乞丐版iPhone用户留了一枚巨大的彩蛋。严格意义上说，彩蛋是给所有iPhone用户留的，但乞丐用户更需要，也更容易吃到这枚彩蛋——信不信，不删除任何一个app、任何一张照片或视频，iPhone自己就会乖乖想办法帮你腾出“海量”可用容量？
彩蛋的用法是这样的：假设iPhone可用容量只剩1GB，那么在iTunes Store里选一部大小超过10GB的电影购买或租用（不用真的买），此时系统会提醒“可用存储空间不足，无法下载”。见证奇迹的时刻来了，这时候你再回去看iPhone可用容量，就会发现它很有可能变成了2GB。还没完，回到iTunes Store重复一遍刚才的动作，你就会发现iPhone可用容量有可能变成了3GB。一直这么做下去，iPhone就会不断想办法继续腾出空间，直到无能为力。这里千万要注意，找一部占用空间很大的电影，否则万一iPhone真腾出了足够的空间，就真开始下载了，这时候就傻眼了。
接下来，看看热腾腾的乞丐iPhone 6从537MB可用容量到3.3GB实例：
1、先查看当前的可用容量，路径“设置——通用——存储空间与iCloud用量”。这里是537MB。
2、打开iTunes Store，选择一部大容量电影。这里选的是《让子弹飞》，1080p高清版4.97GB大小，对这部手机而言足够了。
3、选择“￥1.00购买”，等待弹出“无法下载”的通知。
4、现在去查看可用容量，已经变成了1.6GB（wow，太神奇了，赶紧转给其他乞丐看吧）。
5、重复上述步骤2~3，发现可用容量变成了2.4 GB（是不是不敢相信啊）。
6、再重复上述步骤2~3，发现可用容量变成了3.2 GB（兴奋了没有）。
7、再重复上述步骤2~3，发现可用容量变成了3.3 GB（还有希望）。
8、再重复上述步骤2~3，发现可用容量还是3.3 GB（苹果尽力了）。
9、好了，到此为止。我们来看看苹果做了什么，请注意支付宝图标上的“正在清理…”字样。
也就是说，苹果帮忙清理了它认为不是那么重要的内容，对用户来说没有明显的影响。以支付宝为例，这个臃肿的app平时占用的空间超过500MB，iPhone为了装得下电影，默默选中了它，然后自动干掉了它的某些老的缓存文件，让它占用的空间回到150 MB左右的正常状态。如果你足够细心的话，会发现重新打开支付宝的时候，头像也会重新加载一下，相册里的照片质量也被压缩了。
这枚彩蛋是在 mackungfu.org 上发现的，据说它已经存在很久了。如果你看到本文的时候，苹果已经修复了这个“漏洞”，请不要怪我们。谁让你这么穷的！
