现代智能手机最好的地方之一是它们通常是防水(water resistant)的，但这并不意味着它们完全不受液体引起的问题的影响。
如果您的 iPhone 显示“检测到液体”或“无法充电”，您应该迅速行动以防止损坏您的手机。
不该做什么
在我们讨论如果您看到此液体检测警报应该做什么之前，让我们先从您不应该做的事情开始：
- (Do NOT)在确定没有液体存在之前，
请勿按下紧急覆盖按钮（在某些 iOS 版本中）。(Emergency Override)
- 请勿使用压缩空气(compressed air )吹 Lightning 充电口。
- 不要尝试在您的手机上使用任何其他Lightning配件。
- 请勿将棉签或其他吸水材料插入端口。
- 不要将 iPhone 放入米饭中。严重地。
- 不要尝试使用热量（例如吹风机）来吹干端口或电缆。
最重要的是要记住不要恐慌和耐心等待。我们希望在不损坏手机的情况下解决问题！
移除电缆
如果您在插入Lightning 数据(Lightning)线后收到此警告，请立即拔下数据线。这不仅可以减少短路的可能性（尽管 iPhone 已经在自我保护），而且如果液体是罪魁祸首，它还可以缩短干燥物品所需的时间。
关闭弹出窗口
虽然您不想立即使用“紧急覆盖(Emergency Override)”选项，但使用“解除(Dismiss)”按钮是安全的。这会消除警告通知，但不允许电流流过端口。
如果剩余电池电量充足，您可以继续使用手机并在端口没电时尝试再次充电，但您可以采取一些措施来加快充电速度。
关掉你的电话
最好关闭手机以节省电池电量，直到可以再次充电为止。这也有助于防止进水造成的进一步损坏。
抖掉多余的液体
根据 Apple 自己的官方指南(official guidelines)，您应该尝试清除端口中多余的液体。“过量”液体是指可见的液滴，而不是使物体变湿的薄层水分。拔下数据线后，将手机背面用力敲击手掌，端口朝下，以去除端口中多余的水分。
您可能需要多次执行此操作，直到确定手机中不再有水滴流出为止。抖掉多余的液体后，您应该等待至少 30 分钟再试一次。如果您仍然收到错误消息，则您的手机需要更多时间晾干。
风干你的端口
让港口干涸的最有效方法是顺其自然。将手机放在湿度不太高但通风良好的地方，里面的液体应该会在几个小时内蒸发到空气中。
如果可能，让端口朝下，这样重力可以帮助更快地去除水分。也可以使用硅胶包或其他干式除湿机来降低储物空间的湿度。
请勿将手机置于阳光直射或人造热源附近。这可能会损坏您的设备，在极端情况下，甚至会导致电池起火。
清洁你的闪电端口
Apple强烈建议不要尝试将任何东西放入Lightning端口，例如棉签，尤其是金属针等导电物品。然而，根据我们的经验，USB-C和Lightning端口会随着时间的推移积累碎屑，例如绒毛。这些碎屑可以吸收并长时间保留水分，更不用说会导致Lightning插头松动。
用手电筒检查Lightning端口，确认里面有碎屑。然后，您可以自行承担风险，使用薄的、钝的、不导电的物体轻轻地清除任何碎屑。我们发现扁塑料牙签效果最好。
擦干你的闪电插头
很容易忘记这个问题有两个方面，插入端口的插头是另一个方面。弄干端口，然后将湿塞放回端口，然后重新开始整个循环是没有意义的。
使用(Use)吸水毛巾或类似物品擦干您的 Lighting 插头。将它放在与手机本身相同的低湿度环境中，并给它们类似的时间来晾干。
对于电缆插头，水可能会滞留在金属连接器和塑料护罩之间。一些第三方充电线也可能使用可以收集液体的编织材料。
尝试不同的充电器
在某些情况下，“ Lightning连接器中检测到液体”警告是误报，造成这种误报的常见原因是第三方数据线或充电器。如果您知道电缆和端口都干了，请尝试使用Apple官方硬件或 MFi 认证硬件，以确保这不是错误的设计。亚马逊(Amazon)等网站上有许多未经认证的劣质售后闪电(Lightning)电缆和充电器。
使用无线充电器
仅仅因为你的 iPhone 的闪电端口现在没有接受任何电源并不意味着你的手机注定要死。如果您有 iPhone X 或更新机型，您仍然可以使用无线充电(wireless charging)为您的设备充电。
如果问题需要很长时间才能解决，这将特别有用，因为您可以继续使用手机。
重启手机
如果您已彻底擦干端口和电缆，但在插入手机时仍然出现错误，请尝试重新启动设备(restarting the device)。我们已经看到 iPhone 用户报告在没有实际水的情况下解决了这个问题，这只是一个小故障。
在带有主(Home)屏幕按钮的 iPhone 上，按住侧边按钮，直到看到滑动(Slide)关机消息，然后将滑块向右移动。如果您的 iPhone 较新且没有主(Home)屏幕按钮，则需要同时按住侧边按钮和音量增大按钮才能滑动(Slide)以关闭消息。在这两种情况下，您都需要按下侧边按钮，直到您看到Apple标志以再次打开手机。
何时使用紧急覆盖按钮(Emergency Override Button)
因此，您的 iPhone 没有无线充电功能，或者您没有无线充电功能。您需要立即为手机充电，并且很想按下紧急覆盖(Emergency Override)按钮以再次供电。你应该？
如果您 100% 确定这是误报并且端口中没有液体，请继续使用紧急覆盖。同样(Likewise)，如果您给手机足够的时间晾干，则可以安全地按下该按钮。
但是，这样做需要您自担风险，因为在连接器中的液体流动时让电源流动可能会导致短路并永久损坏您的手机。
疑似液体损坏的迹象
在您的 iPhone 端口检测到水(Water)可能是更大的水损坏的副作用，它通常可以隐藏起来，并且随着时间的推移可能会慢慢损坏您的手机，因为它会渗入设备或引起腐蚀。
尽管您的手机可能被评为防水，但只有当您第一次将其从包装盒中取出时才是正确的。由于经常磨损，防止液体流向不应随时间流逝的地方的密封件可能会随着时间的推移而受到损害。如果手机永远不会被弄湿，这没什么大不了的，但当它掉进一滩水里的那一天，你就会第一次知道密封失效了。
Apple在 2006 年之后生产的所有 iPhone 型号中都安装了液体接触指示器 ( LCI )，并为每个型号提供了一个LCI 位置图表。(chart of the LCI location)
如果您的手机缺少LCI，还有其他迹象。水损坏的一个常见症状是相机内部保护玻璃下方可见水分。物理按钮可能会停止工作，并且您手机的扬声器可能听起来失真。如果您的手机已完全或部分浸入水中，尤其是盐水，很可能会因液体而造成永久性损坏。
发送您的手机进行评估
如果您无法自行解决问题或怀疑发生进水损坏，您应尽快联系Apple到(Apple)Apple Store进行专业评估。打开手机后，Apple支持技术人员会快速确认是否有水渍，如果没有水渍，他们可能会修复Lightning端口。
如果您的手机已投保，您还可以享受水损坏维修或更换服务。不幸的是，Apple Care +保修不涵盖水损坏，但与没有保修相比，维修或更换费用可能会大大降低。
How to Fix Liquid Detected in Lightning Connector on iPhone
One of the best things about modern smartphones is that they’re usuallу water resistant, but that doesn’t mean they’re entirely immune to problems caused by liquids.
If your iPhone says “Liquid Detected” or “charging not available,” you should work quickly to prevent damage to your phone.
What NOT To Do
Before we get into what you should do if you see this liquid detection alert, let’s start with what you shouldn’t do:
- Do NOT press the Emergency Override button (in some versions of iOS) until you’re sure there’s no liquid present.
- Don’t use compressed air to blow out the Lightning charging port.
- Don’t try to use any other Lightning accessory with your phone.
- Refrain from sticking cotton buds or other absorbent materials into the port.
- Don’t put your iPhone in rice. Seriously.
- Don’t try to use heat, such as from a hair dryer, to dry the port or cable.
The most important thing to remember is not to panic and have patience. We want to resolve the problem without damaging the phone!
Remove the Cable
If you get this warning after plugging in a Lightning cable, immediately remove the cable. Not only does this reduce the chances of an electrical short (although the iPhone is already protecting itself), but it will also shorten the time needed to dry things out if a liquid is to blame.
Dismiss the Popup
While you don’t want to use the Emergency Override option immediately, it’s safe to use the Dismiss button. This takes the warning notification away but doesn’t allow current to flow through the port.
If you have enough battery power left, you can keep using your phone and try to charge it again later when the port is dry, although there are some things you can do to speed that up.
Turn Your Phone Off
It’s a good idea to turn your phone off to conserve what battery power you have until you can charge it again. This can also help prevent further damage from water ingress.
Shake Out Excess Liquid
As per Apple’s own official guidelines, you should try and remove excess liquid from your port. “Excess” liquid refers to visible droplets, not the thin layer of moisture that makes something wet. After unplugging your cable, firmly tap the back of your phone against the palm of your hand with the port facing downwards to get rid of excess moisture in your port.
You may want to do this more than once until it’s clear no more droplets are coming out of the phone. After shaking out excess liquid, you should wait at least 30 minutes before trying again. If you still get the error, your phone needs more time to dry.
Air Dry Your Port
The most effective way to dry out your port is to let nature take its course. Place the phone somewhere that doesn’t have too much humidity but has good airflow, and the liquid inside should evaporate into the air over a few hours.
If possible, have the port facing downwards so that gravity can help remove moisture faster. You can also use silica gel packets or other dry dehumidifiers to reduce the humidity in the storage space.
Don’t place your phone in direct sunlight or near an artificial heat source. This can damage your device and, in extreme cases, even cause a battery fire.
Clean Your Lightning Port
Apple strongly advises against trying to put anything into the Lightning port, such as cotton swabs, and especially nothing conductive, such as metal pins. However, in our experience, USB-C and Lightning ports accumulate debris such as lint over time. That debris can absorb and retain water for a long time, not to mention cause a loose fit for your Lightning plug.
Inspect the Lightning port with a flashlight to confirm that there’s debris inside it. Then, at your own risk, you can gently remove any debris with a thin, blunt, non-conductive object. We have found that flat plastic toothpicks work best.
Dry Your Lightning Plug
It’s easy to forget that there are two sides to this problem, with the plug that goes into the port being the other. There’s no sense in drying out your port, then putting a wet plug back into it, and starting the whole cycle again.
Use an absorbent towel or similar object to dry your Lighting plug. Leave it in the same low-humidity environment as your phone itself and give them similar amounts of time to dry out.
In the case of cable plugs, water can be trapped between the metal connector and the plastic shroud. Some third-party charging cables may also use a woven material that can trap liquids.
Try a Different Charger
In some cases, the “liquid detected in Lightning connector” warning is a false positive, and a common cause of this false positive is a third-party cable or charger. If you know that your cable and port are both dry, try using official Apple hardware or MFi-certified hardware to ensure it’s not a faulty design that’s to blame. There are many poorly-made uncertified aftermarket Lightning cables and chargers on sites like Amazon.
Use a Wireless Charger
Just because your iPhone’s Lightning port isn’t accepting any power right now doesn’t mean your phone is doomed to die. If you have an iPhone X or newer, you can still use wireless charging to charge your device.
This is especially useful if the issue takes a long time to resolve since you can simply keep using your phone.
Restart Your Phone
If you’ve thoroughly dried your port and cable but still get the error when you plug in your phone, try restarting the device. We’ve seen iPhone users report this fixing the issue in cases where no actual water was involved, and it was just a glitch.
On iPhones with a Home button, press and hold the side button until you see the Slide to power off message, and then move the slider to the right. If you have a newer iPhone without a Home button, you need to hold the side button and volume up button simultaneously to reach the Slide to power off the message. In both cases, you’ll press the side button until you see the Apple logo to turn the phone on again.
When to Use the Emergency Override Button
So, you have an iPhone that doesn’t feature wireless charging, or you don’t have wireless charging. You need to charge the phone immediately, and you’re tempted to press that Emergency Override button to get the power flowing again. Should you?
If you are 100% certain that this is a false alarm and no liquid is in the port, go ahead and use the emergency override. Likewise, if you’ve given adequate phone time to dry, it could be safe to press that button.
However, you do so at your own risk since letting power flow while the liquid in the connector can cause an electrical short and permanently damage your phone.
Signs of Suspected Liquid Damage
Water detected in your iPhone’s port is perhaps a side effect of greater water damage, which can often be hidden and may slowly damage your phone over time as it penetrates the device or causes corrosion.
Although your phone may be rated as water resistant, that’s only true when you first take it out of the box. With regular wear and tear, it’s possible for the seals that prevent liquid from going where it shouldn’t to be compromised over time. That’s not a big deal if the phone never gets wet, but the day it does fall in a puddle of water would be the first time you’ll know the seals have failed.
Apple has put a liquid contact indicator (LCI) in all iPhones models made after 2006 and offers a chart of the LCI location for every model with one.
If your phone lacks an LCI, there are other signs. A common symptom of water damage is moisture visible inside the camera, below the protective glass. Physical buttons can stop working, and your phone’s speakers may sound distorted. If your phone has been completely or partially immersed in water, especially salt water, there’s a good chance it has permanent damage from a liquid.
Send Your Phone For Evaluation
If you can’t resolve the issue yourself or suspect water damage has occurred, you should contact Apple for professional evaluation at an Apple store as soon as possible. An Apple support technician will quickly confirm water damage after opening the phone, or if there is no water damage, they may be able to repair the Lightning port.
You may also be covered for water damage repairs or replacements if your phone is insured. Unfortunately, the Apple Care + warranty does not cover water damage, but the repair or replacement fee may be significantly reduced compared to not having the cover.
