If you take your eyes off the iPhone a little, it will sleep, which is a problem !? --Why the iPhone can't be heard anymore?

The appeal and strength of the iPhone is that you can understand how to use it without reading the manual. However, there are times when you think you know it but you don't understand it correctly. In this section, we will explain in an easy-to-understand manner "why the iPhone can't be heard anymore". This time, I will answer the question, "If you take your eyes off the iPhone a little, it will sleep, which is a problem !?"

Is it okay for the purpose of the question that there are times when the interval until going to sleep is short and you want to improve it to some extent? Certainly, smartphones, not only iPhone (iOS), have a strong energy saving consciousness and have not been for a while. If the operation status continues, the display will be turned off and various functions will be stopped in "sleep".

During sleep, the system goes into hibernation / lock state, but it wakes up by pressing the home button or other operation, and is unlocked by authenticating the passcode or Touch ID. IPhones with Touch ID enabled can't adjust the time to request a passcode and can only select "immediately", so the specification to sleep when you take your eyes off is a bit cramped. "Moderate" is important for everything.

To extend the sleep interval, tap "Settings" → "Screen display and brightness" → "Auto lock", and then tap 30 seconds / 1 minute / 2 minutes / 3 minutes / 4 minutes / 5 minutes / none. Choose from. If you select "None", the battery will be consumed faster because it will not automatically go to sleep.

Keep in mind that increasing the interval to autosleep reduces security. If your iPhone is stolen, you will have unlimited access to the contents, so it is very dangerous to set it to "None". Considering the balance with energy saving, I think that 1 minute or 2 minutes is "moderate".

By the way, some apps do not sleep at startup. For example, the Video app does not automatically sleep while playing a video. Even for third-party apps, "Pokemon GO" does not sleep no matter how long it is running, and "Yahoo! Map" has a sleep prohibition mode. If you don't want to put it to sleep for a specific purpose, finding an app that doesn't sleep automatically is one way to do it.
