iPad 是 Apple 最受欢迎的产品之一，对于大多数人来说，它提供了他们所需要的所有功能，但它们也有相当大的电池，可能需要一段时间才能充电。
如果您的 iPad 的充电过程比以前慢或太慢而无法满足您的需求，您可以尝试一些方法来帮助解决充电问题。
1. 使用 Apple 数据线和充电器
苹果(Apple)与第三方配件制造商有着有趣的关系。如果您使用的是带有Lightning端口的 iPad，则必须使用经过MFi认证的数据线和 iPad 充电器。与Android上的 USB-C(USB-C)不同，Lightning是Apple的专有标准，配件必须获得许可并包含认证芯片。不幸的是，亚马逊(Amazon)等网站上有大量未经认证的闪电(Lightning)电缆。它们可能会工作一段时间，但在更新后会产生错误。
如果您有使用USB C的 iPad (USB C)Pro或其他型号的 iPad ，则没有专有许可限制。但是，我们仍然建议您使用Apple充电器和数据线，因为这样可以确保正确激活 iPad 的任何快速充电功能。如果没有，iPad 将退回到USB电缆标准，这可能会更慢。这并不是说第三方充电器和数据线无法为您的 iPad 快速充电，但在您购买新数据线或充电器之前，值得检查一下兼容性。
如果您对现有充电器或数据线有疑问，请将您的 iPad 固件更新到最新版本。否则(Otherwise)，请尝试使用不同的充电线或充电器。如果问题出在插座本身，您可能还想尝试不同的壁装插座。检查电源插座是否适用于其他设备。如果没有，请检查断路器以查看电源是否带电。
2. 检查您的数据线(Cable)和充电器(Charger)是否损坏(Damage)
通常，如果您的充电设备损坏，则意味着您的 iPad 无法充电。但是，仍然值得检查您的闪电或USB-C电缆是否有任何损坏。
如果损坏是内部的，您将看不到任何东西。尝试使用另一根您知道可以解决内部电缆损坏问题的电缆。
3. 重启你的 iPad
一个很好的早期故障排除步骤是重新启动您的 iPad(restart your iPad)。在带有Home按钮的 iPad 上，按住顶部按钮（以前是电源按钮）直到出现“滑动关闭”消息，然后按照说明进行操作。
如果您的 iPad 没有主(Home)屏幕按钮，请按住顶部按钮以及音量增大按钮或音量减小按钮。将出现相同的消息，因此只需滑动滑块即可关闭 iPad。
无论您拥有哪种 iPad，按住顶部按钮都会将其打开。按住(Press)按钮，直到您看到Apple 标志(Apple Logo)。
4.检查端口是否有碎片
闪电端口和USB-C端口是可逆的，因此您可以将它们放入，而不必担心它们是否正确排列。这非常方便，但这些设计也倾向于将碎屑推入端口，尤其是在USB-C的情况下。当杂物堆积在充电端口中时，它会阻止充电电缆保持一致的接触。
使用一罐压缩空气是从端口吹出碎屑的一种方法。在USB-C的情况下，我们已经成功地使用细塑料牙签轻轻地去除端口上的棉绒，这样插头就可以一直插进去。
湿气损坏也可能会降低端口内触点的导电性，但这需要专业技术人员进行评估。如果您的 iPad 在端口附近被弄湿后开始缓慢充电，这是一个值得考虑的可能性。
5. 检查 iPad 电池健康
现代移动设备中常见的锂离子电池寿命有限。通常(Generally)，大约 500 次完全充电循环后，iPad 最大容量中的电池开始下降。如果电池的化学开始有任何问题或暴露在高温下，这种退化可能会更快发生。所以你的充电问题实际上可能是电池问题。
如果您的 iPad 充电缓慢、充电时变得非常热、不能长时间保持充电，或者在电池方面表现异常，您可能需要更换电池。遗憾的是，与 iPhone iOS 和 macOS 系列不同，iPad 没有内置在 iPadOS 中的电池健康指示器。因此，您必须将其带到经过认证的维修店进行评估。幸运的是，在保修期内更换电池对于 iPad 来说并不是那么昂贵，如果在保修期内出现问题，更换将是免费的。
6. 充电时不要使用(Use Your)iPad
在 iPad 上遇到充电缓慢的一个常见原因是您在充电时使用了耗电的应用程序。如果 iPad 的电力消耗接近适配器的电力流入，那么你只是在涓流充电。更糟糕的是，您可能仍在缓慢地清空电池。
(Heavy)由于CPU和GPU的努力工作，游戏等重型应用程序将使 iPad 发热。iPad 温度越高，出于安全原因，电池充电速度就越慢。
因此，坚持使用轻量级应用程序，或者在充电时根本不使用 iPad，您可能会看到电池电量表更快地充满。
7. 不要用电脑充电
将 iPad 连接到计算机或任何其他低输出设备的USB端口将默认为标准 5W (USB)USB充电。这会为您的 iPad 缓慢充电或只会减慢电池放电速度。您可能会收到一条消息“此 iPad 未在充电”，这表明当 iPad 从端口获取电力时，还不足以为电池充电。这是将 iPad 连接到Mac或Windows PC 以使用 iTunes 时的常见消息。
一些计算机主板具有2.1 安培和更高功率级别的高输出USB端口。(USB)尽管如此，对于像 iPad 这样大且耗电的东西来说，这是一个糟糕的选择，因为现在有足够的电流来增加所需的瓦数。
8. 购买更快的充电器
每台 iPad 都附带一个电源适配器，但不一定是能够以最大速度为其充电的电源适配器。例如，一些 iPad Pro 可以充电至 30W，但仅配备 18W 充电器。
最大充电速度因您拥有的 iPad 型号而异，因此请查看特定 iPad 的充电速度，然后将其与符合或超过该瓦数的充电器匹配。
如果您有MacBook Pro充电器，您还可以使用它更快地为 iPad 充电，他们可以快速让 iPad 充满电。另一方面，如果您使用 iPhone 充电器为平板电脑供电，则需要很长时间。
9.关闭(Wireless Features Off)iPad 或无线功能
您可以通过减少从电池中消耗的电量来加快 iPad 的充电速度。充电速率和功耗差距越大，电池充电的速度就越快。
您可以在设备充电时关闭任何您不需要的东西。例如，关闭控制中心的蓝牙(Bluetooth)、Wi-Fi或蜂窝数据以降低功耗。使用飞行(Airplane)模式将杀死任何耗电的无线功能。
调低屏幕亮度也会产生很大影响。要获得最大充电率，请完全关闭 iPad。这将确保不会产生与充电无关的热量，当然，您的 iPad 的耗电量可以忽略不计。
10. 准备 iPad 进行维修(Repair)或交易(Trade)
如果您的 iPad 电池已达到其使用寿命，您可以让专业人士更换它，或者用它换取少量商店信用以购买新设备。正如我们之前提到的，Apple 更换 iPad 电池的定价并非不合理。使用新电池后，如果您的平板电脑处于良好的工作状态，并且电池寿命恢复到出厂时的状态，那么您的平板电脑将可以使用更多年。
无论(Regardless)您选择哪个选项，请确保您已完成设备最近的 iCloud 或iTunes备份，以便在您拿回 iPad 或购买新 iPad 时恢复它。或许更重要的是，在将充电缓慢的 iPad 交给Apple商店之前，请确保您进行了完整的出厂重置。
警惕(Be Wary)第三方更换
电池(Third-party Battery)
尝试通过让第三方服务更换 iPad 电池来节省一点钱是很诱人的。虽然使用经过认证的第三方维修公司没有任何问题，但我们强烈建议您避免将第三方电池放入您的 iPad，因为存在电池故障甚至危险火灾的巨大风险。始终遵循Apple支持的建议，以确保您最终拥有安全的产品。
Is Your iPad Charging Slow? 10 Best Ways to Fast-Charge
The iPad is one of Apple’s most populаr products, and for most people, it offers all the features they’ll ever need, but they also have sizable batteriеs that can take a while to charge.
If your iPad’s charging process is going more slowly than before or just too slowly for your needs, there are several things you can try to help troubleshoot charging problems.
1. Use an Apple Cable and Charger
Apple has an interesting relationship with third-party accessory makers. If you’re using an iPad with a Lightning port, you must use a cable and iPad charger that is MFi certified. Unlike USB-C on Android, Lightning is Apple’s proprietary standard, and accessories must be licensed and contain an authentication chip. Unfortunately, there are plenty of uncertified Lightning cables on sites like Amazon. They might work for a while but produce errors after an update.
If you have an iPad Pro or another model of iPad that uses USB C, then there’s no proprietary license restriction. However, we still recommend that you use an Apple charger and cable, since that ensures that any fast-charging feature of the iPad is correctly activated. If not, the iPad will fall back on the USB cable standard, which may be slower. That’s not to say that third-party chargers and cables can’t fast-charge your iPad, but it’s worth checking for compatibility before you buy a new cable or charger.
If you have issues with an existing charger or cable, update your iPad firmware to the latest version. Otherwise, try a different charging cable or a different charger. You may also want to try a different wall outlet, in case the problem is with the outlet itself. Check that the power outlet works with other devices. If not, check your circuit breakers to see if the power source is live.
2. Check Your Cable and Charger for Damage
Usually, if your charging equipment is damaged, it means that your iPad won’t charge. However, it’s still worth checking your lightning or USB-C cable for any damage.
You will not see anything if the damage is internal. Try another cable you know is working to eliminate internal cable damage as a problem.
3. Reboot Your iPad
A good early troubleshooting step would be to restart your iPad. On iPads with a Home button, press and hold the top button (formerly the power button) until the “Slide to Turn Off” message appears, then do as instructed.
If you have an iPad without a Home button, press and hold the top button along with either the volume up button or volume down buttons. The same message will appear, so simply slide the slider to turn the iPad off.
Holding the top button will turn it on regardless of which iPad you have. Press and hold the button until you see the Apple Logo.
4. Check the Port for Debris
Lightning Ports and USB-C ports are reversible, so you can put them in without worrying about getting them lined up correctly. This is very convenient, but these designs also tend to push debris into the port, especially in the case of USB-C. When debris builds up in the charging port, it can prevent the charging cable from making consistent contact.
Using a can of compressed air is one way to blow debris from the port. In the case of USB-C, we’ve had success using thin plastic toothpicks to gently remove lint from the port so that the plug can go all the way in.
Moisture damage can also potentially reduce the conductivity of the contacts inside the port, but this requires assessment by a professional technician. If your iPad has started charging slowly after getting wet near the port, this is a possibility worth considering.
5. Check iPad Battery Health
The lithium-ion batteries common in modern mobile devices have a limited lifespan. Generally, after around 500 full charge cycles, the battery in your iPad’s maximum capacity starts to fall. This degradation can happen more quickly if the battery has any issues with its chemistry to start with or has been exposed to high temperatures. So your charging issue might actually be a battery issue.
If your iPad charges slowly, gets very hot while charging, doesn’t hold a charge for long, or otherwise acts strangely when it comes to its battery, you may need to replace the battery. Sadly, unlike iPhone iOS and macOS range, iPads don’t have a battery health indicator built into iPadOS. So you’ll have to take it to a certified repair shop for assessment. Luckily, replacing a battery out of warranty isn’t all that expensive for iPads, and if it’s gone wrong within the warranty period, the replacement will be free.
6. Don’t Use Your iPad While Charging
A common reason to experience slow charging on an iPad is that you’re using power-hungry apps while charging. If the power draw of the iPad is close to the inflow of power from the adapter, then you’re only charging by a trickle. Even worse, you may still be emptying the battery slowly.
Heavy apps such as games will heat up the iPad thanks to the CPU and GPU working hard. The hotter the iPad, the slower the battery has to be charged for safety reasons.
So stick to lightweight apps, or don’t use your iPad at all while charging, and you’ll likely see the battery meter fill up more quickly.
7. Don’t Charge From a Computer
Connecting your iPad to the USB port on a computer or any other low-output device will default to standard 5W USB charging. This will either charge your iPad slowly or will only slow down battery discharge. You may get a message saying, “This iPad is not charging, ” which indicates that while the iPad is getting power from the port, it’s not enough to charge the battery. This is a common message when connecting an iPad to a Mac or Windows PC to use iTunes.
Some computer motherboards have high-output USB ports with 2.1 Amps and higher wattage levels. Still, it’s a poor choice for recharging something as large and power-hungry as an iPad since there’s just now enough amperage to add up to the required wattage.
8. Buy a Faster Charger
Every iPad ships with a power adapter, but not necessarily a power adapter that can charge it at maximum speed. Some iPad Pros, for example, can charge up to 30W but only come with an 18W charger.
The maximum charge speed differs based on which model of iPad you have, so look up the charging speed for your particular iPad and then match it with a charger that meets or exceeds that wattage.
If you have a MacBook Pro charger, you can also use it to charge your iPad more quickly and they can quickly get an iPad to full power. On the other hand, if you’re using an iPhone charger to power your tablet, it’s going to take a long time.
9. Turn Your iPad or Wireless Features Off
You can speed up how quickly your iPad charges by reducing the power it’s drawing from the battery. The bigger the charge rate and power consumption gap, the faster the battery will charge.
You can turn off anything you don’t need while the device is charging. For example, turn off the Control Center’s Bluetooth, Wi-Fi, or cellular data to reduce power consumption. Using Airplane mode will kill any power-sapping wireless features.
Turning down your screen brightness can have a big impact as well. To get the maximum charge rate, switch your iPad off completely. This will ensure that no heat that’s not related to charging is generated, and, of course, your iPad will have negligible power draw.
10. Prep Your iPad for Repair or Trade
If your iPad’s battery has reached the end of its useful life, you can either have it replaced professionally or trade it in for a small amount of store credit to buy a new device. As we mentioned before, Apple’s pricing to replace the battery in an iPad isn’t unreasonable. With a new battery, your tablet will last many more years if it’s otherwise in good working order with its battery life restored to factory-new.
Regardless of which option you choose, ensure you have completed a recent iCloud or iTunes backup of your device, so you can restore it when you get your iPad back or buy a new iPad. Perhaps more importantly, make sure you do a complete factory reset before handing your slow-charging iPad over to the Apple store.
Be Wary of Third-party Battery Replacement
It can be tempting to try and save a little money by having a third-party service replace your iPad’s battery. While there’s nothing wrong with using a certified third-party repair company, we strongly advise avoiding putting a third-party battery in your iPad since there is a huge risk of battery failure and even dangerous fires. Always follow the advice from Apple support to ensure you have a safe product in the end.
