您的手机需要永远达到 100% 吗？您是否经常发现自己在问“为什么我的手机这么慢？” 是不是经常发生？还是偶尔发生的事情？为什么会这样？最重要的是，你能做些什么来加快充电速度？
有几个因素会影响智能手机的充电速度。这些因素因智能手机类型、充电配件、充电习惯等而异。在本指南中，您将找到手机充电如此缓慢的 5 个可能原因以及如何解决问题。
在继续之前，请确保您没有从弱电源输出/电源充电。您的 PC 的USB端口、劣质移动电源(power banks)或车载充电器可能无法像插入墙上插座的电源适配器那样为您的手机充电。如果您的手机已插入电源插座但充电仍然缓慢，请继续阅读下一部分以找出原因。
1.充电(Faulty Charging)配件不兼容或故障
通过充电配件(charging accessories)，我们谈论的是您的电源砖、USB电缆和充电板/垫子——如果您是无线充电的话。当您的手机开始缓慢充电时，首先要检查这些。
确保(Make)您的电源适配器的输出额定值（安培数）足以为您的手机充电。安培(Amperage)数描述了电源适配器能够为您的手机提供的电流量。充电器的安培数越低，充满电池所需的时间就越长。
尽管您的手机只能消耗其设计的电量，但使用具有高安培数的电源砖会增加快速充电的机会。例如，如果您的手机支持 1.6 安培，则使用 2.1 安培适配器比 1 安培适配器为手机充电的速度更快。请注意，手机只会使用/接收来自适配器的最大容量（即 1.6A）。
要享受快速充电，请使用至少 2 至 3 安培的电源砖(a power brick with at least 2 – 3 amps)。这并不意味着您的手机会以两倍的速度充电，它只会保证您的手机充电速度与设计速度一样快。
此外，请确保您使用的是状况良好的正品电缆。由于频繁的人工处理、扭曲和过度折叠/弯曲， USB(USB)电缆很容易损坏 - 特别是在电缆连接到手机的位置。
这是手机充电缓慢的常见原因。一个好的电源适配器 + 一个坏的USB 数据(USB)线会像坏的电源适配器 + 一个好的USB 数据(USB)线一样为您的手机充电。检查您的USB电缆并检查是否有外部损坏。
建议始终使用开箱即用手机随附的充电配件。或您的智能手机制造商推荐的充电配件。如果您的手机未随附充电器，请确保从授权商店购买正品充电器。
尝试使用不同的USB数据线和电源适配器，但请确保它具有推荐的安培数（或更高）来为手机充电。
2.您使用的是无线充电器
无线充电技术很酷(Wireless charging technology is cool)很花哨，但也有几个缺点。这些限制之一是充电速度慢。无线充电板给手机充电的速度比电缆慢。手机(Phone)壳可能会进一步降低无线充电速度，因此请确保在将设备放在无线平板上之前取下手机壳。
如果您的手机仍然无法快速充电，请使用数据线并检查是否有影响。
3. 充电端口问题
如果充电端口损坏，您的设备充电速度会比平时慢。被困在端口中的异物(Foreign)会阻碍电流从充电电缆传输到手机。这也可能会减慢充电过程。使用手电筒检查手机的充电端口，检查是否有灰尘、棉绒和污垢。
如果您在充电口的金属触点上发现颗粒，请使用牙签或软刷小心地将它们清除。尽可能轻柔，以免将颗粒进一步推入端口。更好(Better)的是，使用一罐压缩空气清洁端口。许多智能手机技术人员建议这样做更安全。
注意：(Note:) 避免(Avoid)用嘴将空气吹入充电口。呼吸中的水蒸气(Water)会腐蚀端口并对手机造成严重损坏。此外，您不应使用尖锐的金属物体（如针、别针或回形针）清洁端口。
4.后台应用
后台运行的应用程序过多会导致手机电池耗尽更快并且充电缓慢。这就像试图用洞装满一个桶。后台应用程序是智能手机中的漏洞；来自充电器的能量将同时为您的电池充电并为后台活动供电。这会减少可用于为电池充电的电量。
查看手机的电池使用情况，并为您几乎不使用的应用禁用后台电池使用。在Android上，启动设置(Settings)应用程序，选择电池(Battery)，点击右上角的三点图标，然后选择电池使用情况(Battery usage)。
寻找消耗大量电池的少量使用的应用程序。选择应用程序并点击背景限制(Background restriction)。
接下来，点击限制(Restrict)以阻止应用在后台使用电池。
要在 iPhone 或 iPad 上查看后台应用程序，请转到设置(Settings)>电池(Battery)并点击显示活动(Show Activity)以查看应用程序在屏幕上和后台花费的时间。
如果您发现一个未使用的应用程序的电池使用量和后台时间很高，请关闭该应用程序并查看您的手机现在是否可以正常充电。您还应该为耗电的应用禁用后台应用刷新(background app refresh)；转到设置(Settings)>常规(General)>后台应用刷新(Background App Refresh)。这可能有助于减少应用程序的后台活动。
5.您的电池旧或有缺陷
没有什么可以天长地久。人、财富、痛苦，甚至连你手机的电池都没有。可充电电池的性能、容量和效率往往会随着时间的推移而降低。用了两年的智能手机的电池耗电速度会比新手机快。同样(Likewise)，您的手机充电速度也会更慢。
when your battery’s capacity hits 80% or lower，iOS 和 iPadOS 会自动降低设备性能和充电速度。要检查 iPhone 或 iPad 的电池容量，请前往“设置”(Settings) > “电池(Battery)” > “电池健康(Battery Health)” 。如果最大容量(Maximum Capacity)为 80% 或更低，则电池已达到使用寿命，需要更换。
如果您的 iPhone 或 iPad 仍在保修期内，您可以在授权的Apple 服务中心免费更换电池。(Apple Service Center)否则，您需要付费才能更换旧电池。
Android没有用于检查电池健康或寿命的本机工具；使用第三方电池应用程序或访问服务中心以确定您的电池状况。如果您的手机使用时间超过 2 到 3 年，您的电池很可能有缺陷。
0% 到 100% 真实快速
除了上述之外，您还应该避免在充电时使用手机。这样做会导致手机充电速度变慢、电池温度升高并增加充电线磨损的机会。既然您已经了解了一些良好的充电习惯，请查看如何保护和延长设备的电池寿命(ways to preserve & extend your device’s battery life)。
Why Is My Phone Charging So Slow? 5 Possible Reasons
Is your phone taking forever to get tо 100%? Do you often find yourself asking “Why is my phone ѕo slow?” Іs it a frequent occurrence? Or something that happens once in a while? Why does thіs hapрen? Most іmportantly, what can you do to speed uр charging speed?
There are several factors that influence charging speed on smartphones. These factors vary according to smartphone type, charging accessories, charging habits, and so on. In this guide, you’ll find 5 possible reasons why your phone is charging so slow and how to resolve the problem.
Before you proceed, make sure you aren’t charging from a weak power output/source. Your PC’s USB ports, low-quality power banks, or car chargers may not charge your phone as fast as a power adapter plugged into a wall socket. If your phone is plugged into an electric socket but continues to charge sluggishly, proceed to the next section to find out why.
1. Incompatible or Faulty Charging Accessories
By charging accessories, we’re talking about your power brick, USB cable, and charging pad/mat—if you charge wirelessly. These are the first things to check when your phone begins to charge really slowly.
Make sure your power adapter has an output rating (amperage) sufficient to charge your phone optimally. Amperage describes the amount of electric current a power adapter is able to supply to your phone. The lower a charger’s amperage, the longer it takes to fill up your battery.
Although your phone can only take as much power as it’s designed to, using a power brick with a high amperage increases the chances of rapid charging. If, for example, your phone supports 1.6amps, using a 2.1amps adapter will charge your phone faster than a 1amps adapter. Note that the phone will only use/receive its maximum capacity (i.e. 1.6A) from the adapter.
To enjoy quick charging, use a power brick with at least 2 – 3 amps. That doesn’t mean your phone will charge twice as fast, it’ll only guarantee that your phone charges as fast as it’s designed to.
Additionally, make sure you’re using an authentic cable that’s in good condition. USB cables get damaged easily due to frequent manhandling, twisting, and excessive folding/bending—particularly at the point where the cable connects to your phone.
This is a common reason phones charge slowly. A good power adapter + a bad USB cable will charge your phone just as slow as a bad power adapter + a good USB cable. Examine your USB cable and check for external damages.
It is recommended to always use the charging accessories that ship with your phone out-of-the-box. Or charging accessories that your smartphone manufacturer recommends. If your phone doesn’t ship with a charger, make sure you purchase an authentic charger from an authorized store.
Try using a different USB cable and power adapter, but make sure it has the recommended amperage (or higher) to charge your phone.
2. You’re Using a Wireless Charger
Wireless charging technology is cool and fancy, but it has several shortcomings. One of these limitations is the slow charging rate. A wireless charging pad will charge your phone relatively slower than a cable. Phone cases may further reduce wireless charging speed, so make sure you remove the case before placing your device on the wireless pad.
If your phone still isn’t charging fast enough, use a cable and check if that makes a difference.
3. Problems with Your Charging Port
Your device will charge slower than usual if the charging port is damaged. Foreign materials trapped in the port can obstruct the transfer of electrical current from the charging cable to your phone. This may also slow down the charging process. Examine your phone’s charging port using a flashlight and check for dust, lint, and dirt.
If you find particles on the metal contacts in the charging port, use a toothpick or a soft brush to carefully get them out. Be as gentle as you can, so you don’t push the particles further into the port. Better yet, use a can of compressed air to clean the port. That’s safer and recommended by many smartphone technicians.
Note: Avoid blowing air into the charging port with your mouth. Water vapor from your breath can corrode the port and cause serious damage to your phone. Also, you shouldn’t clean the port with sharp metal objects like needles, pins, or paper clips.
4. Background Apps
Having too many apps running in the background will cause your phone’s battery to drain faster and charge sluggishly. It’s just like trying to fill a bucket with holes. Background apps are the holes in your smartphone; energy from your charger will simultaneously charge your battery and power background activities. This reduces the amount of power available to charge your battery.
Go through your phone’s battery usage and disable background battery usage for apps that you barely use. On Android, launch the Settings app, select Battery, tap the three-dot icon at the top-right corner, and select Battery usage.
Lookout for sparingly used apps consuming a high percentage of your battery. Select the app and tap Background restriction.
Next, tap Restrict to stop the app from using the battery in the background.
To view background apps on an iPhone or iPad, go to Settings > Battery and tap Show Activity to see how much time apps have spent on-screen and in the background.
If you find an unused app with high battery usage and background time, close the app and see if your phone now charges normally. You should also disable background app refresh for the battery-hogging apps; go to Settings > General > Background App Refresh. That could help reduce the apps’ background activities.
5. Your Battery Is Old or Defective
Nothing lasts forever. People, wealth, pain, and not even your phone’s battery. The performance, capacity, and efficiency of rechargeable batteries tend to decrease over time as they age. The battery of your two-year-old smartphone will drain faster than when it was new. Likewise, your phone will charge more slowly.
iOS and iPadOS will automatically slow down device performance and charging speed when your battery’s capacity hits 80% or lower. To check your iPhone or iPad’s battery capacity, go to Settings > Battery > Battery Health. If the Maximum Capacity is 80% or lower, the battery has hit its lifespan and needs to be replaced.
You can get a free battery replacement at an authorized Apple Service Center if your iPhone or iPad is still under warranty. Otherwise, you’ll pay a fee to have your old battery replaced.
Android doesn’t have a native tool for checking battery health or lifespan; use a third-party battery app or visit a service center to determine your battery’s condition. You most likely have a defective battery if your phone is over 2 – 3 years old.
0% to 100% Real Quick
In addition to the above, you should also avoid using your phone while charging. Doing so causes your phone to charge at a slow rate, raises battery temperature, and increases the chances of fraying your charging cable. Now that you’ve learned some good charging practices, check out ways to preserve & extend your device’s battery life.
