折叠屏手机使用中的常见误区

折叠屏手机可以折叠，但你的钥匙不该跟着一起折。使用折叠屏手机时，最常犯的错误就是摔手机。不过这属于常识，讨论起来也没什么意思。你大概在想的是内屏——损坏内屏最常见的方式，就是在合上手机时夹到了不该夹的东西。三星的折叠屏护理页面警告称，卡片、硬币或钥匙都可能划伤甚至刺穿Galaxy折叠屏的内屏。

这听起来够简单：合上手机前，确认车钥匙没搁在屏幕上就行。但如果你从事特别脏的工作，或者住在海边，事情就复杂了。灰尘不一定肉眼可见，而海滩上的沙子更是无孔不入。

要知道，并非所有折叠屏手机都一样结实。有些折叠屏比其他型号更柔软、更脆弱。例如，Galaxy Z Fold8和Fold8 Ultra具备IP48防护等级，而新款iPhone Duo则号称达到IP68。第一位数字表示对固体异物的防护程度：4意味着直径1毫米以上的物体无法进入，6则代表设备完全防尘。

内屏需要小心对待

折叠屏的内屏和传统直板手机的屏幕完全不同。它毕竟要折叠，所以别以为可以像按压普通手机外层玻璃那样用力按它。这包括你可能想都没想就做过的动作，比如用指甲去抠屏幕上的一个小颗粒。

另一个常见错误是把出厂预贴的内屏保护膜撕掉，误以为那只是运输用的临时保护。早期确实很容易撕，但现在边缘已经内收，藏得更好了。三星强烈建议不要动这些保护层。反过来，也不要自己在折叠屏上贴未经认证的屏幕保护膜。这类手机和直板手机不一样，随便一张保护膜是不行的。只能使用厂商明确列出与该型号兼容的保护膜或触控笔。

你不必把折叠屏手机当宝贝供着，尽管从传统智能手机换过来会让人觉得需要如此。这些注意事项只是要求你在处理折叠屏时稍微讲究一些：避免任何集中受力，合上手机时确保中间什么都没有。

折叠屏手机的寿命有多长？

折叠屏手机没有固定的寿命，但有一些参考指标。比如，我们知道厂商测试铰链和屏幕时，会反复折叠20万到50万次。如果你每天打开手机100次，那大约相当于5到10年。

但这并不是保证。三星声称Galaxy Z Fold7的屏幕在实验室测试中经过50万次折叠后仍能正常工作。听起来很令人安心，但受控测试并不意味着Fold7在日常生活中也能承受那么多次开合。过去，三星对初代Galaxy Fold宣称的20万次折叠就未能兑现。听到这些数字时，把它们当作大致基准和营销数据就好。

此外，合上手机前检查有没有灰尘，远比每天数折叠次数有用。不要用力按压屏幕，也不要使用不匹配的触控笔。屏幕上有痕迹时，用软布擦拭，而不是用指甲去抠。虽然IP68听起来很棒，但苹果指出iPhone Duo的防水防尘性能可能会随着日常磨损而下降。没有什么是永久耐用的，而有活动部件的设备磨损会更快。

使用折叠屏手机时应避免的常见错误

你的手机可以对折，但你的钥匙不该跟着一起折。

使用折叠屏手机时应避免的最常见错误就是把它们摔了。但这是常识，拿来讨论也没什么意思。你大概在想的是内屏，而损坏内屏最常见的方式，就是在合上手机时夹到了不该夹的东西。三星的折叠屏养护页面警告说，卡片、硬币或钥匙都可能划伤甚至刺穿Galaxy折叠屏的内屏。

这听起来够简单明了：合上手机之前，确认车钥匙没有搁在屏幕上就行。但如果你干的是特别脏的活儿，或者住在海边，事情就复杂了。灰尘不是总能一眼看到，而沙滩上的沙子更是无孔不入。

要记住，并非所有折叠屏手机都处于同等水平。有些折叠屏比其他的更软、更脆弱。比如Galaxy Z Fold8和Fold8 Ultra具备IP48防护等级，而新款iPhone Duo则号称达到IP68。第一位数字描述的是对固体异物的防护程度：4表示1毫米及以上的物体无法进入，6则表示设备防尘密封。

Common mistakes you should avoid when using foldable phones
Your phone can fold in half, but your keys shouldn’t join it.
The most common mistake you should avoid when using foldable phones is dropping them. But that's common knowledge and doesn't make for a very exciting discussion. You're probably thinking about the inside foldable screen, where the most common way to damage it is closing it on something that shouldn't be there. Samsung's foldable care page warns that cards, coins or keys can scratch or even puncture a Galaxy foldable's inner display.
That seems straightforward enough; just make sure your car keys aren't sitting on top of your phone when you try to close it. But if you work a particularly dirty job or live near the beach, that complicates matters. You can't always spot dirt easily, and beach sand will find its way into absolutely anything.
Keep in mind that not all foldables are on equal footing. Some foldable screens are a bit softer and weaker than others. The Galaxy Z Fold8 and Fold8 Ultra, for instance, have an IP48 rating, whereas the new iPhone Duo boasts an IP68. The first digit describes the degree of protection against solid objects; a 4 means objects 1mm thick or larger can't enter, while 6 indicates a dust-tight device.
Treat the inner screen with care
A foldable's inner screen is far from a conventional slab-phone display. It has to fold, after all, so don't assume you can press on it as firmly as you would on a standard phone's outer glass. That includes actions you've probably done without thinking, like scratching a speck from the screen with your nail.
Another mistake is peeling off a factory-applied inner screen film because it looks like disposable shipping protection. This was surprisingly easy to do early on, but now the edges are tucked in and better hidden. Samsung highly recommends leaving these protective layers alone. On the flipside, don't stick an unapproved screen protector over a foldable display. These phones aren't like their slab cousins, so any old screen protector won't do. Only use a protector or stylus the manufacturer specifically lists as compatible with that model.
You don't have to baby a foldable phone, though it may seem that way coming from a traditional smartphone. These precautions just require you to be a little more particular when handling the folding screen. Avoid any concentrated force or closing it on anything other than open air.
What is the lifespan of a foldable phone?
There is no specific lifespan for foldables, though there are suggestions and indicators. For instance, we know that manufacturers test the hinges and screens by folding the phones between 200,000 and 500,000 times. If you open your phone 100 times a day, that would be 5 to 10 years.
However, that's not a guarantee. Samsung claimed the Galaxy Z Fold7's display remained functional after 500,000 folds in lab testing. Sounds pretty reassuring, but a controlled test doesn't mean the Fold7 would survive that many opens and closes throughout your daily life. In the past, Samsung's claim of 200,000 folds on the original Galaxy Fold fell short. When you hear figures tossed around, treat them as general benchmarks and marketing numbers.
Besides, it's far more useful to check for dirt before you close the phone than to count your folds each day. Don't push heavily on the display or use the wrong stylus. Use a soft cloth to clean marks on the screen instead of digging at them with your fingernail. And while the IP68 rating sounds great, Apple notes that the iPhone Duo's water and dust resistance may diminish with normal wear. Nothing lasts forever, but wear increases faster when moving parts are involved.
