在美国，85% of cellphone users own a smartphone。这意味着可能有很多不那么智能的手机把满是灰尘的抽屉弄得乱七八糟。然而，在你把这些手机扔进垃圾桶之前（实际上，根本不要这样做），为什么不考虑一下你可以用旧手机做的事情之一。
1. 把它扔进后备箱(Trunk)以备不时之需
旧手机的电池可以使用数天甚至数周。你可以买一张预付费的SIM 卡(SIM card)，给它充上一点通话时间，然后把它放在车里以备不时之需。请记住(Remember)每隔几个月打开手机以检查电池。
2. 捐赠给可以使用的人
较旧的手机非常适合拨打电话和使用短信。许多人仍然使用该基本功能。将原本运行良好的旧手机捐赠给 Goodwill 风格的商店或当地慈善机构可能是一个不错的起点。
3.建立一些很酷的东西
尽管被认为已经过时，但旧手机仍然是复杂的技术。您会在互联网上找到许多项目，这些项目详细说明了如何使用旧手机或只是零件用于各种酷项目。
如果您可以使用Arduino或其他等效的微控制器，那么重新利用旧手机的范围就会显着扩大。一个很好的例子是将您的旧手机用作GSM 模块(GSM module)，而不是购买专用设备。
4. 拍摄复古照片
虽然您可能不想用旧手机的摄像头替换三星 S21 Ultra(Samsung S21 Ultra)来拍摄主流照片，但人们对具有复古魅力的照片的喜爱与日俱增。您可以尝试使用复古滤镜，但没有什么能比得上使用老式相机设备。
使用旧相机拍摄当代事物的照片特别有趣，而旧相机手机是开始这项爱好的好方法。
5.用它来断开连接
人们越来越担心智能手机如何导致强迫性和成瘾行为。通知和信息的不断滴落让我们着迷，即使我们应该关闭并重新充电我们的精神能量。
您无法运行社交媒体应用程序(social media apps)的旧手机可能是完美的度假手机。它仍然可以让人们在紧急情况下与您取得联系，但它不会一直试图引起您的注意。因此，当您下一次度假时，也许可以将智能手机留在家中，然后打包那个简单的手机。
6. 用作 MP3 播放器
尽管如今人们都在关注音乐流媒体，但始终有专用音乐播放器的空间。与其带着昂贵而脆弱的智能手机去听音乐，何不用你最喜欢的MP3(MP3s)加载你的旧手机呢？结合旧的HiFi系统，您的旧手机也可以制作一个可维修的点唱机，即使网络中断也能正常工作。
7.玩经典手机游戏
很容易忘记，在智能手机出现之前，已经有很多值得体验的手游。今天的复古(Retro)游戏非常庞大，但它不仅限于经典游戏机，如NES或旧DOS游戏。一个很好的例子是Doom RPG。
经典动作射击游戏的出色回合制。当然，您可以在模拟器上运行这些游戏，但没有什么比在原始硬件上体验它们更好的了。
8. 将其用作基本调制解调器
虽然旧手机无法做到这一点，但大多数新一代功能手机都可以用作调制解调器。它们可能只支持较慢的数据标准，例如EGPR(EGPRs)或 3G，但这对于各种项目或低带宽用例可能仍然足够。
9. 把它拆开来取乐
如果您无论如何都要摆脱旧手机，为什么不借此机会了解一下您使用的小工具呢？不用担心破坏重要的东西，拿出一些螺丝刀，把那部旧手机拆开。您甚至可以在YouTube(YouTube)等网站上搜索该手机型号的拆解指南，这将帮助您识别不同的组件。
好消息是，如果您不想，您不必将它们重新组合在一起。尽管如此，这确实给你留下了一堆电子产品，在你用完旧手机之前只剩下最后一个选择。
10. 回收它！
有两个很好的理由不让旧手机最终被丢弃。首先(First)，这些金属在某些情况下可能是有害的。尽管现代电子产品减少或减少了有毒物质，但其中总有一些。
其次，手机可能含有黄金和铜等稀有物质，很难从普通垃圾场中提取出来。最好将您的旧手机送到回收商处，然后将这些稀有材料重新投入流通以供新设备使用。有冲突矿物(conflict minerals)之类的东西，通过回收你的手机，你可以帮助减少这个问题，即使只是一点点。
10 Things You Can Do With Your Old Cellphones
In the United States, 85% of cellphone users own a smartphone. That means there’s probably a lot of not-so-smart phones cluttering up dusty drawers. However, before you throw those phones in the trash (actually, don’t do that at all), why not consider one of these things you can do with your old cell phones.
1. Throw It in the Trunk for Emergencies
Older phones had batteries that lasted days or even weeks. You could buy a prepaid SIM card, load it up with a bit of talk-time, and leave it in your car for emergencies. Remember to switch the phone on every few months to check the battery.
2. Donate It to Someone Who Can Use It
Older cell phones are perfectly fine for making calls and using text messages. Many people still have a use for that basic functionality. Donating old phones that otherwise work well to a Goodwill-style store or a local charity may be a good place to start.
3. Build Something Cool
Despite being considered obsolete, older phones are still sophisticated pieces of technology. You’ll find many projects on the internet that detail how you can use old phones or just parts for various cool projects.
If you can get your hands on an Arduino or another equivalent microcontroller, the scope for repurposed old phones opens up significantly. One good example is using your old phone as a GSM module instead of buying a dedicated unit.
4. Take Retro Photos
While you may not want to replace your Samsung S21 Ultra with an old phone’s camera to take your mainstream photos, there’s a growing love for pictures with a retro charm. You can try using a retro filter, but nothing lives up to using old-fashioned camera equipment.
It’s especially fun to take photos of contemporary things using old cameras, and an old camera phone is a great way to get started with this hobby.
5. Use It to Disconnect
There’s growing concern about how smartphones are causing compulsive and addictive behaviors. The constant drip of notifications and information keeps us hooked, even when we should be switching off and recharging our mental energy.
Your old cellphone, incapable of running social media apps, might be the perfect vacation phone. It still lets people get in touch with you in an emergency, but it’s not constantly trying to get your attention. So when you take your next vacation, maybe leave the smartphone at home and pack that simple phone instead.
6. Use It as an MP3 Player
While people are all about music streaming these days, there’s always room for a dedicated music player. Instead of going for a run with your expensive and fragile smartphone for music, why not load up your old phone with your favorite MP3s? Combined with an old HiFi system, your old phone can make a serviceable jukebox, too, one that will work even when the network is out.
7. Play Classic Phone Games
It’s easy to forget that before smartphones, there were already plenty of mobile games worth experiencing. Retro gaming is enormous today, but it’s not limited to classic gaming consoles like the NES or old DOS games. One great example is Doom RPG.
An excellent turn-based take on the classic action-shooter. Sure, you can run these games on an emulator, but nothing beats experiencing them on the original hardware.
8. Use It as a Basic Modem
While this isn’t possible with old phones, most late-generation feature phones can be used as a modem. They might only support slower data standards such as EGPRs or 3G, but that may still be enough for various projects or low bandwidth use cases.
9. Take It Apart for Fun
If you were going to get rid of your old phone anyway, why not take this as an opportunity to learn a little about the gadgets you use? Without any fear of breaking something important, get out some screwdrivers and take that old phone apart. You can even search for a teardown guide for that phone model on sites like YouTube, which will help you identify the different components.
The good news is that you don’t have to put it all back together again if you don’t want to. Still, that does leave you with a pile of electronics, which leaves just one last option before you’re done with your old phone.
10. Recycle It!
There are two excellent reasons not to let old cell phones end up in a dump. First, those metals can be harmful in some circumstances. Although modern electronics reduce or minimize toxic substances, there are always some in there.
Second, cell phones may have rare substances like gold and copper, and it’s hard to extract them from a regular dump. It’s better to send your old phone to the recycler and put those rare materials back into circulation for use with new devices. There is such a thing as conflict minerals, and by recycling your phone, you help reduce that issue, if only by a little.
