iPhone、iPad 和 iPod touch 上较短的屏幕锁定超时可以保护设备的数据免遭未经授权的访问,延长电池寿命,并最大限度地降低(preserves battery life)OLED烧屏的风险。但是,如果您希望屏幕在忙于活动的过程中保持打开状态,可能会导致您感到沮丧。
您可以快速增加默认屏幕超时,甚至完全阻止其自动锁定,只需简单访问 iOS 和 iPadOS 中的自动锁定选项屏幕即可。

(Increase Auto-Lock Time-Out)增加iPhone 和 iPad 上的
自动锁定超时
默认情况下,iPhone 或 iPod touch 的屏幕会在 30 秒不活动后锁定。如果您使用 iPad,自动锁定会在 2 分钟后启动(Apple 平板电脑设备的最短超时设置)。
您可以通过以下步骤增加 iPhone、iPad 和 iPod touch 的屏幕超时:
- 通过主屏幕(Home Screen)或应用程序库(App Library)打开Apple设备的“设置”(Settings)应用程序。
- 向下滚动(Scroll)并点击显示(Display)和亮度(Brightness)类别。
- 点击自动锁定。
- 选择您想要的屏幕超时 — 1 分钟、2 分钟、3 分钟、4 分钟、5 分钟或从不(Never)。在 iPad 上,可用选项包括 5 分钟、10 分钟、15 分钟和从不(Never)。

有趣的事实:如果您使用配备 Face ID 的 iPhone 或 iPad(use an iPhone or iPad with Face ID)(例如 iPhone X),系统软件会依靠一种名为“注意力感知”(Attention Awareness)的功能,仅在您将视线从屏幕上移开后才开始自动锁定倒计时。
(Decrease Auto-Lock Timeout)减少iPhone 和 iPad 上的
自动锁定超时
如果您想缩短 iPhone、iPad 或 iPod touch 上的屏幕超时持续时间,只需重新访问自动锁定设置屏幕(前往“Settings > Display和Brightness > Auto-Lock”)并选择较短的时间即可。
然而,减少自动锁定持续时间的快速方法是激活低功耗模式(activate Low Power Mode)。该功能有助于节省电池寿命,并自动强制屏幕在 30 秒后超时,无论您的自动锁定偏好如何。
要激活低功耗模式:
- 打开设置。
- 点击电池。
- 启用或禁用低功耗模式(Low Power Mode)旁边的开关。

启用低功耗模式(Low Power Mode)的更快方法是使用控制中心(Control Center)上的低功耗模式(Low Power Mode)切换开关。如果不存在,请转至Settings > Control Center并将低功耗模式(Low Power Mode)添加到活动控件列表中。您还可以等到电池电量降至 20%,然后点击自动低电量提示上的(Low Battery)低电量模式(Low Power Mode)按钮。
自定义iPhone 和 iPad 上的
超时持续时间(Time-out Duration)
在 iPhone、iPad 或 iPod touch 上更改屏幕锁定超时非常简单。如果您要增加自动锁定持续时间,请记住安全性降低、电池消耗更快和显示质量下降等缺点,并根据需要手动缩短超时时间或激活低功耗模式

How to Change Screen Timeout on Your iPhone or iPad
The shorter screen loсk time-out on the iPhone, iPad, and iPоd touch protects the device’s data from unauthorized access, preserves battery life, and minimizes the risk of OLED burn-in. However, it can cause frustration if you want the screen to remain on during activities where you’ve got your hands full.
You can quickly increase the default screen time-out, or even stop it from automatically locking altogether, with a brief visit to the auto-lock options screen in iOS and iPadOS.

Increase Auto-Lock Time-Out on iPhone and iPad
By default, the screen on your iPhone or iPod touch locks after 30 seconds of inactivity. If you use an iPad, auto-lock kicks in after 2 minutes (the shortest timeout setting for Apple’s tablet devices).
You can increase the screen timeout for the iPhone, iPad, and iPod touch with the following steps:
- Open the Settings app of your Apple device via the Home Screen or App Library.
- Scroll down and tap the Display & Brightness category.
- Tap Auto-Lock.
- Pick the screen timeout you want—1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes, or Never. On the iPad, available options are 5 minutes, 10 minutes, 15 minutes, and Never.

Fun Fact: If you use an iPhone or iPad with Face ID (e.g., an iPhone X), the system software relies on a feature called Attention Awareness to begin the auto-lock countdown only after you look away from the screen.
Decrease Auto-Lock Timeout on iPhone and iPad
If you want to decrease the screen time-out duration on your iPhone, iPad, or iPod touch, simply re-visit the auto-lock settings screen (go to Settings > Display & Brightness > Auto-Lock) and pick a shorter period.
However, a quick way to decrease the auto-lock duration is to activate Low Power Mode. It’s a feature that helps conserve battery life and automatically forces the screen to time out at 30 seconds, regardless of your auto-lock preference.
To activate Low Power Mode:
- Open Settings.
- Tap Battery.
- Enable or disable the switch next to Low Power Mode.

A faster way to enable Low Power Mode is to use the Low Power Mode toggle on the Control Center. If it isn’t present, go to Settings > Control Center and add Low Power Mode to the list of active controls. You can also wait until the battery dips to 20 percent and tap the Low Power Mode button on the automatic Low Battery prompt.
Customize the Time-out Duration on iPhone & iPad
Changing the screen lock time-out on your iPhone, iPad, or iPod touch is easy. If you’re increasing the auto-lock duration, keep the downsides, such as reduced security, faster battery drain, and display degradation, in mind, and manually lower the time-out or activate Low Power Mode as you see fit.
