没有什么比插入您的Apple iPhone 并且没有听到熟悉的叮当声表明它正在充电更糟糕的了。或者，当电缆反复断开时，您可能会一遍又一遍地听到铃声。
如果您的 iPhone 充电端口似乎松动，导致耳机、充电器和其他配件无法正常工作，您需要考虑多种原因和修复方法。
1. 这不是港口(Port)；这是电缆
大多数情况下，iPhone 用户所说的“松散端口”与端口本身松散无关。相反，Lightning电缆插头可能松散地位于端口内，因此不会充电或保持原位。
为了排除您的电缆是罪魁祸首，最明智的做法是尝试使用不同的电缆，看看它是否也看起来“松动”。如果其他电缆也有同样的问题，您应该将故障排除的注意力转向端口。如果只有特定的电缆或电缆品牌有问题，那么谜团就解决了。
Lightning标准是Apple的专有标准，第三方Lightning线缆必须经过认证。如果您使用的是未经认证的电缆，它可能不符合Apple规定的物理或电气要求。
2. 你的手机掉了吗？
在某些时候，您的 iPhone 可能掉了，在大多数情况下，您的手机会很好，但如果它以错误的方式撞击地面，这可能会损坏端口。如果Lightning端口与手机主板之间的连接出现裂痕或松动，可能会停止运行或仅间歇运行。
如果您的端口问题在手机掉落后不久就开始出现，即使它看起来只是很小的跌落，也可能是原因所在。
3.可能是水害
虽然现代 iPhone 被评为高度防水，包括端口，但该评级是在使用蒸馏水进行测试时完成的。自来水(Tap)、雨水和海水含有会腐蚀内部端口的污染物。如果您的 iPhone 端口暴露在腐蚀性物质中，可能会影响端口的导电性和物理完整性，从而导致握持松动。
解决方案？最好对您的手机进行专业评估。长时间接触海水等液体会造成损坏。如果液体暴露损坏了您的端口，则很有可能它会渗透到手机的其他部分。技术人员可以检查手机主板的不同部分是否明显腐蚀，并会从那里为您提供建议。通常，腐蚀损坏的修复并不经济。
4.去除棉绒和灰尘堆积
充电端口感觉松动的最常见原因是每次插入数据线时，都会将少量碎屑推入端口。
随着这些碎片在端口中堆积，电缆连接变得越来越浅。最终，电缆会感到松动，因为它没有整个端口长度来支撑它，并且电气连接可能无法接触或变得不可靠。
值得庆幸的是，这是您通常可以在家中解决的问题。许多指南建议使用一罐压缩空气，但我们发现这并不是那么有效，而且您冒着导致港口内冷凝水的风险。
相反，请使用细木牙签或塑料牙签从端口背面轻轻舀出碎屑。轻轻地(Gently)在港口周围工作，尽可能多地清理干净。
这也适用于 Apple 的 iPad Pro平板电脑和三星 Galaxy(Samsung Galaxy)或Google Pixel等(Google Pixel)Android手机上的USB 端口(USB ports)。但是，请注意端口中间的灵活中央连接器标签。当您进入拨片时，它会稍微弯曲，但如果牙签太厚，它可能会损坏这个组件。我们更喜欢塑料刀片状的牙签来完成这项任务，而不是圆形的木制牙签。
请勿使用金属物体（例如金属针）清洁端口。您不仅会物理损坏您的端口，而且还会冒着使引脚短路的风险。
5.改用无线充电
自 iPhone 8 以来，Apple已将无线充电(wireless charging)作为 iPhone 的一项功能。这不是一个永久的解决方案，但如果您的 Lightning 端口出现问题，您可以使用无线充电器为其充电，直到您可以购买新手机或找到时间和金钱进行维修。不幸的是，如果您仍在使用 iPhone 7 或更旧的型号，这将不是一个选择。
闪电(Lightning)端口现在只用于充电，因为它的数据传输速度太慢以至于已经过时了。使用无线充电功能唯一要牺牲的就是一点充电速度，当然，如果你没有充电板，你就必须买一个充电板，但现在它们非常便宜。
6. 进行专业维修
如果您的端口损坏、松动、故障或其他无法挽救的问题，下一步是将其带到专业维修店进行充电端口维修或更换全新端口。拆开 iPhone 需要特殊工具，拆卸和更换端口必须由合格人员完成。
Apple已开始提供DIY自助维修服务，您可以租用工具来拆开新的 iPhone 12s 或 iPhone 13s，以进行常见的维修，例如更换电池或维修屏幕。可悲的是，不支持像 iPhone 11 或仍然流行的 iPhone 6 这样的旧手机进行DIY维修，但无论如何，Lightning 端口更换不包括在内，而且这不是你在家里的厨房桌子上修理的东西。
7.不要乱(Mess)用保修期内的(Warranty)手机(Phone)
如果您的 iPhone 仍在标准保修期内，或者您通过购买Apple Care+延长了保修期，那么您在任何情况下都不应尝试自行解决问题。
即使您的手机不再处于保修期内，如果您的端口因液体接触或跌落等事故而损坏，如果您有手机保险单，您也可能会受到保护。
8. 您的手机可能(May)因其他原因无法充电
在端口的症状与端口“松散”的看法之间存在得出错误结论的风险。按照设计，充电端口有一些字面上的摆动空间，所以要小心，不要认为问题背后有一点轻微的松动。
您的 Lightning 端口无法正常工作还有许多其他可能的原因。您的充电电缆或适配器可能有故障或未经认证。尝试替代方案是排除这种可能性的快速方法。
您手机的电池可能有故障或磨损。这通常表现为电池寿命不佳，但也可能意味着您的设备拒绝充电。如果您的手机在插入Lightning 数据(Lightning)线时无法开机，则可能是电池坏了，而不是充电器端口。更换 iPhone 电池并不昂贵，技术人员对您的手机的一般评估是一种快速且廉价的方式来找出充电问题背后的原因。之后，您可以决定与新手机的成本相比，维修或部件更换是否具有经济意义。
如果您的手机仍处于开机状态，您可以使用 iOS 的电池健康功能(battery health feature)来检查您的电池是否报告了任何问题。
不要尝试狡猾的维修建议
根据我们在论坛和社交媒体上看到的抱怨，“松散”的照明和USB-C端口似乎并不少见，遗憾的是，正确修复它可能会花费适中的费用或需要一部全新的手机。因此，许多 iPhone 用户可能想要尝试DIY维修是可以理解的。
不幸的是，网上有很多不好的建议和无效的修复。我们已经看到建议使用金属针清洁端口，将手机放入米饭中以消除液体损坏，或在端口内部用电工胶带衬里以使插头更好地粘住。这些“解决方案”都不是有效的，并且会使您的问题恶化。最后，如果您无法通过上述基本建议解决问题，请让技术人员对您的手机进行评估是您的最佳选择。
大多数维修店会向您收取一笔不可退还的小额费用，以安全打开手机并检查其是否损坏。如果事实证明维修太贵、不可能或根本不值得，他们会简单地再次关闭手机，而不会再向您收取任何费用。
8 Reasons Why Your iPhone Charging Port Is Loose (And How to Fix)
There are few things worse than plugging in your Apple iPhone and not hearing that familiar ding to indicate it’s charging. Or, maybe you hear the chіme over and over again аs the cable repeatedly disconneсts.
If it seems that your iPhone charging port is loose, preventing headphones, chargers, and other accessories from working, there are several causes and fixes you’ll want to consider.
1. It’s Not the Port; It’s The Cable
Most of the time, what iPhone owners describe as a “loose port” has nothing to do with the port itself being loose. Instead, the Lightning cable plug might sit loosely within the port and, therefore, won’t charge or stay put.
To rule out your cable as the culprit, the most sensible thing to do is try a different cable to see if it also seems “loose.” If other cables have the same issue, you should turn your troubleshooting attention to the port. If only a specific cable or cable brand has the problem, then the mystery is solved.
The Lightning standard is a proprietary Apple standard, and third-party Lightning cables must be certified. If you’re using an uncertified cable, it may not match the physical or electrical requirements Apple mandates.
2. Did You Drop Your Cell Phone?
At some point, you’ve probably dropped your iPhone, and in most cases, your phone will be just fine, but if it hits the ground the wrong way, this may have damaged the port. If the connection between the Lightning port and the phone’s mainboard is cracked or loose, it may cease to function or only function intermittently.
If your port problems started shortly after dropping the phone, even if it seemed like a small drop, this might be the cause.
3. It Could Be Water Damage
While modern iPhones are rated to be highly water resistant, including the port, that rating is done while testing with distilled water. Tap water, rainwater, and seawater contain contaminants that can corrode your port on the inside. If your iPhone’s port has been exposed to corrosive substances, it may affect both electrical conductivity and the physical integrity of the port, leading to a loose grip.
The solution? It’s best to get your phone professionally assessed. Exposure to liquids like seawater can cause damage over a prolonged period. If liquid exposure has damaged your port, there’s a fair chance it’s penetrated other parts of the phone. A technician can check to see if corrosion is apparent in different parts of the phone’s mainboard and will advise you from there. Usually, corrosive damage isn’t economical to repair.
4. Remove Lint and Dust Buildup
The most common reason charging ports feel loose is that every time you insert the cable, you push a small amount of debris into the port.
As this debris builds up in the port, the cable connection becomes increasingly shallow. Eventually, the cable will feel loose since it doesn’t have the entire port length to support it, and the electrical connection may not make contact or become unreliable.
Thankfully, this is something you can usually fix at home. Many guides recommend using a can of compressed air, but we’ve found that this isn’t all that effective, and you run the risk of causing water condensation within the port.
Instead, use a skinny wooden toothpick or plastic toothpick to gently scoop out the debris from the back of the port. Gently work around the port and clean out as much as you reasonably can.
This also works for USB ports found on Apple’s iPad Pro tablets and Android phones like the Samsung Galaxy or Google Pixel. However, be mindful of the flexible central connector tab in the middle of the port. It will tolerate a little flex as you enter the pick, but if the toothpick is too thick, it may damage this component. We prefer plastic blade-like toothpicks for this task rather than round wooden ones.
Do not use a metallic object, such as a metal pin, to clean the port. Not only can you physically damage your port, but you run the risk of shorting the pins.
5. Use Wireless Charging Instead
Since the iPhone 8, Apple has included wireless charging as a feature in iPhones. It’s not a permanent solution, but if your Lightning port is giving you issues, you can use a wireless charger to keep it topped up until you can get a new phone or find the time and money for a repair. Unfortunately, this won’t be an option if you’re still rocking an iPhone 7 or an older model.
The Lightning port is only ever used for charging these days since its data transfer speeds are so slow as to be obsolete. The only thing you’ll be sacrificing by using the wireless charging function is a bit of charging speed, and of course, you’ll have to buy a charging pad if you don’t have one, but they are incredibly cheap these days.
6. Get It Professionally Repaired
If your port is broken, loose, faulty, or otherwise beyond salvation, the next step is to take it to a professional repair shop for a charging port repair or replacement with a brand new port. Taking an iPhone apart requires special tools, and removing and replacing a port has to be done by a qualified person.
Apple has started offering a DIY self-repair service where you can rent the tools to take apart the new iPhone 12s or iPhone 13s to perform common repairs such as battery replacements or screen repairs. Sadly, older phones like the iPhone 11 or still-popular iPhone 6 aren’t supported for DIY repair, but in any event, Lightning port replacement is not included, and this is not something you fix at home on a kitchen table.
7. Don’t Mess With a Phone Under Warranty
If you have an iPhone that’s still under the standard warranty or you’ve extended the warranty by purchasing Apple Care+, then you should under no circumstances try to fix the issue itself.
Even if your phone isn’t under warranty anymore, if your port was damaged due to an accident such as liquid exposure or a fall, you may be covered under your phone’s insurance policy if you have one.
8. Your Phone May Not Be Charging for Other Reasons
There’s a risk of drawing a false conclusion between the symptom of a port that doesn’t work with the perception that the port is “loose.” By design, there’s some literal wiggle room in charging ports, so be careful that you don’t assume a bit of mild looseness is behind your problems.
There are many other plausible reasons why your Lightning port doesn’t work. You might have a faulty or uncertified charging cable or adapter. Trying alternatives is a fast way to rule this possibility out.
Your phone’s battery may be faulty or worn out. This usually manifests as poor battery life, but it can also mean that your device refuses to charge. If your phone doesn’t turn on when plugging in a Lightning cable, it may be a busted battery, not the charger port. An iPhone battery isn’t expensive to replace, and a technician’s general assessment of your phone is a quick and inexpensive way to find out what’s behind your charging issues. After which, you can decide if the repair or part replacement makes financial sense compared to the cost of a new phone.
If your phone is still on, you can use the battery health feature of iOS to check if your battery reports any issues.
Do Not Try Dodgy Repair Advice
“Loose” Lighting, and USB-C ports don’t seem all that uncommon based on the complaints we’ve seen in forums and on social media, and sadly getting it fixed properly may cost a moderate fee or require an entirely new phone. So it’s understandable that many iPhone owners may want to attempt a DIY repair.
Unfortunately, there’s a lot of bad advice and invalid fixes to be found online. We’ve seen advice to use a metal pin to clean out the port, putting the phone in rice to undo liquid damage, or lining the inside of the port with electrical tape to make plugs stick better. None of these “solutions” are effective and can worsen your problem. In the end, getting your phone assessed by a technician if you can’t resolve the issue with the basic advice above is your best option.
Most repair shops will charge you a small non-refundable fee to safely open the phone and check it for damage. If it turns out that a repair is too expensive, impossible, or simply not worth it, they’ll simply close the phone back up again without charging you any more money.
