iPhone 上的手电筒是一项方便的功能，您可以在帐篷中阅读、晚上遛狗时寻找掉落的钥匙等时使用。

它可能不如袖珍手电筒那么亮，但当您需要时，它会产生足够的光线。不幸的是，软件故障或错误可能导致该功能出现故障，或者 iPhone 电池电量不足可能会阻止手电筒工作。

不管是什么情况，当你的 iPhone 手电筒不工作时，你可以尝试一些事情。  

当 iPhone 上的手电筒不工作时该怎么办^{(What to Do When the Flashlight on Your iPhone Is Not Working)}

您可以从iPhone的控制中心^{(Control Center)}找到您的手电筒。如果您不小心将其删除，您可以在“设置”^(Settings)应用中快速添加该功能。

1. 打开设置^(Settings)应用程序（齿轮图标）并点击控制中心^{(Control Center)}。

1. 滚动到更多控件^{(More Controls)}下的手电筒^(Flashlight)，然后点击旁边的添加(+) 符号。^(Add)手电筒^(Flashlight)现在是控制中心^{(Control Center)}的一部分。

为你的 iPhone 充电^{(Charge Your iPhone)}

如果您的iPhone 电池电量^{(iPhone’s battery)}严重不足，或者您的手机非常冷或非常热，手电筒可能无法工作。

在尝试再次使用手电筒之前，请为您的 iPhone^{(Charge your iPhone)}充满电并确保它已降至正常温度。

关闭相机应用^{(Close the Camera app)}

如果您的iPhone 的相机应用程序^{(iPhone’s Camera app)}处于打开状态，手电筒可能会停止工作。如果两者同时启用，可能会发生冲突，因为相机闪光灯和手电筒使用相同的灯泡工作。

关闭相机^(Camera)应用程序并检查手电筒是否工作。

检查亮度滑块^{(Check the Brightness Slider)}

亮度滑块可帮助您调整 iPhone 上的手电筒亮度。如果您以前使用过手电筒并且忘记增加亮度级别，请尝试将其设置回全亮并查看灯是否重新亮起。 

只需按住手电筒按钮，直到它拉起亮度滑块，然后您就可以调整亮度。

更新 iOS^{(Update iOS)}

有时您的 iPhone 手电筒可能会由于错误或待更新的更新而停止工作。您可以更新iOS，然后检查手电筒是否再次工作。 

注意^(Note)：在更新 iOS 之前，请将您的 iPhone 备份^{(back up your iPhone)}到 iCloud 或您的计算机。

1. 在 iPhone 上轻点“设置”^(Settings) > “通用”。^(General)

1. 接下来，点击软件更新^{(Software Update)}。

1. 如果有多个更新，请选择要安装的更新，然后点击下载并安装^{(Download and Install)}。

使用 Siri 打开 iPhone 手电筒^{(Use Siri to Turn On the iPhone Flashlight)}

如果您无法通过“设置”^(Settings)应用启用手电筒，您可以使用 Siri^{(use Siri)}将其打开。

1. 点按设置^(Settings)> Siri 和搜索^{(Siri & Search)}。

1. 打开收听“Hey Siri”^{(Listen for “Hey Siri” )}并在锁定时允许 Siri^{(Allow Siri When Locked)}。

1. 接下来，说“嘿 Siri，打开手电筒”^{(Hey Siri, turn the flashlight on)}或“嘿 Siri，打开我的手电筒”^{(Hey Siri, turn on my flashlight)}。如果有效，您可以再次使用Siri关闭手电筒。

重启你的 iPhone^{(Restart Your iPhone)}

^{(Restart your iPhone)}如果手电筒仍然无法工作，请重新启动您的 iPhone以解决任何错误或软件问题。这会重置一些导致 iPhone 功能或应用程序出现故障的临时设置。要重置，请使用以下说明：

• iPhone X、11、12：按住音量或侧边^(Side)按钮。
• iPhone SE（第 2^{(iPhone SE (2)}代）、6、7、8 ^{( gen), 6, 7, 8)：(nd)}按住侧边按钮。
• iPhone：SE（第 1^{(iPhone: SE (1)代(st)}），五台或更早^{( gen), five or older)}：按住顶部按钮。

重置 iPhone 设置^{(Reset iPhone Settings)}

重置 iPhone 设置时，您不会丢失任何数据或媒体。 

注意：^(Note:)所有设置，包括位置、网络、隐私以及字典和键盘，都将重置为默认值或删除。

1. 点按设置^(Settings)>常规^(General)。

1. 点击重置^(Reset)。

1. 点击重置所有设置^{(Reset All Settings)}>确认^(Confirm)并检查您的手电筒是否工作。

将您的 iPhone 恢复到以前的备份^{(Restore Your iPhone to a Previous Backup)}

如果您的 iPhone 手电筒仍然无法工作，请尝试使用 iCloud从以前的备份中恢复您的 iPhone。^{(previous backup)}这是修复损坏或丢失数据的一种方法，这可能会导致手电筒发生故障。在开始该过程之前，将 iPhone 连接到WiFi和电源。^(WiFi)

注意：^{(Note: )}这只能作为最后的手段。仅当您有可以恢复的备份时才应该这样做，否则您将丢失 iPhone 上所有以前的数据。您可以检查您拥有的最新备份或创建新备份，如下所示。 

1. 点击设置^(Settings)，然后点击顶部的您的姓名。  

1. 点击 iCloud。^{(Tap iCloud.)}

1. 点击iCloud 备份。 ^{(iCloud Backup. )}

1. 您现在可以查看上次备份的时间。通过单击立即^{( Back Up Now)}备份来执行备份，以确保在重置手机之前备份所有最新数据。 

1. 现在返回设置^(Settings)>常规^(General)>重置^(Reset)。

1. 选择擦除所有内容和设置^{(Erase All Content and Settings)}。

1. 选择立即擦除^{(Erase Now)}，并在出现提示时输入您的密码。

1. 选择擦除 iPhone^{(Erase iPhone)}并确认操作。输入您的Apple ID和密码^(password)，然后再次选择“抹掉 iPhone^{(Erase iPhone )} ” 。 

注意：^{(Note: )}第 8 步会抹掉您的数据，但会用 iCloud 备份替换它。

1. 您将在屏幕上看到Apple标志和进度条。进度条完成并且您的 iPhone 重新启动后，请登录 iCloud。
2. 在应用程序和数据^{(Apps & Data)}屏幕中点击从 iCloud 备份恢复。^{(Restore from iCloud Backup)}

1. 选择一个备份并按照屏幕上的说明从 iCloud 备份恢复您的 iPhone。

现在您可以测试您的手电筒是否正常工作。

iPhone手电筒不工作时要尝试的其他事情^{(Other Things to Try When the iPhone Flashlight Is Not Working)}

如果上述解决方案均无效，请尝试以下故障排除步骤：

• 将您的 iPhone 重置为出厂设置。确保在重置 iPhone^{(reset the iPhone)}之前备份所有数据，因为它会删除所有数据。
• 如果手电筒不起作用并且手电筒按钮像往常一样亮起，则可能是硬件问题。请联系 Apple 支持^{(Contact Apple Support)}或将其送去维修。如果您的 iPhone 仍在保修期内，您可以免费维修。

您可能不会每天都使用 iPhone 的手电筒，但当您需要它时，它会是一项有用的功能。希望^(Hopefully)这些解决方案之一对您有用。 

9 Fixes When iPhone Flashlight Not Working

The flashlight on your iPhone is a convenient feature уou сan uѕe when reading in a tent, looking for dropped keys while walking your dog at night, etc.

It may not be as bright as a pocket flashlight, but it creates more than enough light when you need it in a pinch. Unfortunately, a software glitch or bug can cause the feature to malfunction, or a low iPhone battery can prevent the flashlight from working.

Whatever the case may be, there are a few things you can try when your iPhone flashlight is not working.  

What to Do When the Flashlight on Your iPhone Is Not Working

You can find your flashlight from the Control Center on your iPhone. If you’ve accidentally removed it, you can quickly add the feature back in the Settings app.

1. Open the Settings app (gear icon) and tap Control Center.

1. Scroll to Flashlight under More Controls and tap the Add (+) sign next to it. Flashlight is now part of the Control Center.

Charge Your iPhone

If your iPhone’s battery is critically low or your phone is very cold or very warm, the flashlight may not work.

Charge your iPhone fully and make sure it’s down to a normal temperature before trying to use the flashlight again.

Close the Camera app

The flashlight may stop working if your iPhone’s Camera app is on. If both are enabled simultaneously, there may be a conflict since the camera flash and the flashlight use the same bulb to work.

Turn off the Camera app and check if the flashlight works.

Check the Brightness Slider

The brightness slider helps you adjust the flashlight brightness on your iPhone. If you’ve used your flashlight before and forgot to increase the brightness levels, try to set it back to full and see if the light comes back on. 

Just press and hold the flashlight button until it pulls up the brightness slider and then you can adjust the brightness.

Update iOS

Sometimes your iPhone flashlight may stop working due to a bug or pending update. You can update iOS and then check whether the flashlight works again. 

Note: Before updating iOS, back up your iPhone to iCloud or to your computer.

1. Tap Settings > General on your iPhone.

1. Next, tap Software Update.

1. If there’s more than one update, select the update you want to install and then tap Download and Install.

Use Siri to Turn On the iPhone Flashlight

If you can’t enable the flashlight via the Settings app, you can use Siri to turn it on.

1. Tap Settings > Siri & Search.

1. Turn on Listen for “Hey Siri” and Allow Siri When Locked.

1. Next, say Hey Siri, turn the flashlight on or Hey Siri, turn on my flashlight. If it works, you can use Siri again to turn off the flashlight.

Restart Your iPhone

Restart your iPhone to resolve any bugs or software problems if the flashlight is still not working. This resets some of the temporary settings that cause your iPhone’s features or apps to malfunction. To reset, use the following instructions:

• iPhone X, 11, 12: Press and hold the Volume or Side button.
• iPhone SE (2^nd gen), 6, 7, 8: Press and hold the Side button.
• iPhone: SE (1^st gen), five or older: Press and hold the top button.

Reset iPhone Settings

When you reset your iPhone settings, you won’t lose any data or media. 

Note: All settings, including location, network, privacy, and the dictionary and keyboard, will be reset to their defaults or removed.

1. Tap Settings > General.

1. Tap Reset.

1. Tap Reset All Settings > Confirm and check if your flashlight works.

Restore Your iPhone to a Previous Backup

If your iPhone flashlight still doesn’t work, try restoring your iPhone from a previous backup using iCloud. This is one way to repair corrupted or lost data, which may cause the flashlight to malfunction. Connect the iPhone to WiFi and power before you start the process.

Note: This should only be used as a last resort. You should only do this if you have a backup that you can restore or else you will lose all your previous data on the iPhone. You can check the latest backup you have or create a new backup, as shown below. 

1. Tap Settings and then your name at the top.  

1. Tap iCloud.

1. Tap iCloud Backup. 

1. You can now see when your last backup was made. Perform a backup by clicking Back Up Now to make sure you have all the latest data backed up before resetting your phone. 

1. Now go back to Settings > General > Reset.

1. Select Erase All Content and Settings.

1. Select Erase Now, and enter your passcode if prompted.

1. Select Erase iPhone and confirm the action. Enter your Apple ID and password and select Erase iPhone again. 

Note: Step 8 erases your data, but it’ll replace it with the iCloud backup.

1. You’ll see the Apple logo and progress bar on your screen. Once the progress bar completes and your iPhone restarts, sign in to iCloud.
2. Tap Restore from iCloud Backup in the Apps & Data screen.

1. Select a backup and follow the on-screen instructions to restore your iPhone from an iCloud backup.

Now you can test whether your flashlight is working.

Other Things to Try When the iPhone Flashlight Is Not Working

If none of the above solutions worked, here are some troubleshooting steps to try:

• Reset your iPhone to factory settings. Make sure you backup all your data before you reset the iPhone because it’ll delete all your data.
• If the flashlight won’t work and the flashlight button lights up, as usual, you may have a hardware issue. Contact Apple Support or take it in for repair. If your iPhone is still under warranty, you can get it repaired for free.

You may not use your iPhone’s flashlight every day, but it can be a helpful feature when you need it. Hopefully, one of these solutions worked for you.
