As a lot as I hate listening to it from any assist particular person making an attempt to assist me with a tech drawback, I additionally ask the notorious “Have you ever tried turning it on and off?” query when serving to others with numerous points. The query applies to iPhone and Android units, similar to some other laptop. A restart can repair issues with the software program, and it’s among the many best issues you may take into account. Even when it’s simply to have the satisfaction of telling the particular person making an attempt that can assist you that you simply already did it.
However iPhones shutting down by themselves after which restarting isn’t the type of function you need. You wouldn’t need that from any laptop until you set automated shutdown and restart timers. Some customers have skilled such a annoyance on iPhones just lately, and it is likely to be one more severe bug that Apple has to repair.
Since this phenomenon seems to happen at night time, you’d haven’t any method of realizing it occurred until it impacted your alarm schedule otherwise you checked for it. Fortunately, there’s a straightforward technique to test in case your iPhone shut down and decide how lengthy it stayed off.
The random iPhone 15 shutdowns began showing after the iOS 17.0.3 replace. As we defined a number of days in the past, Apple might need to concern one other fast repair for this explicit drawback.
As a reminder, iOS 17.0.3 ought to have fastened the iPhone 15 Professional/Max overheating drawback. It did that to some extent, though some individuals are nonetheless complaining in regards to the increased temperatures than anticipated.
It’s unclear at the moment whether or not the iOS 17.0.3 launch launched the shutdown bug. Additionally, it won’t be simply iPhone 15 house owners who expertise the problem.
There’s a thread on Reddit the place some customers say older fashions have skilled what is likely to be a shutdown concern. Some went by way of the identical drawback with older iPhones prior to now. The Redditor who began the thread defined that the alarms of two iPhones of their family didn’t go off. When somebody identified the shutdown bug, the Redditor mentioned their system didn’t present a niche within the battery settings.
Examine the battery settings
Alarms failing to ring within the morning generally is a symptom of random shutdowns. The one technique to inform whether or not your iPhone turned itself off by itself is to go to the Settings app, scroll to the Battery part, and search for the graph under.
Since iPhones are virtually all the time turned on, the graph reveals the evolution of battery cost in the course of the day. Seeing a number of lacking bars signifies the cellphone was off for a number of hours. After all, you’d see related gaps if you happen to ran out of battery. However then once more, most individuals recharge their iPhones at night time, so the battery isn’t the problem.
There may be one caveat. In case your iPhone restarts instantly after shutting down, you gained’t see any lacking bars within the graph above.
Some folks may say that iPhones turning themselves off after which again on once more won’t be an enormous drawback. However the alarms failing, as a result of the cellphone might need been off, is an enormous concern. To not point out that you simply’d be unreachable whereas the cellphone is off. Calls and texts wouldn’t undergo from family members who may want fast assist.
It’s unclear why iPhones with this concern solely shut down in the course of the night time.
Take note of Face ID not working within the morning
The alarm failing to ring as a result of the handset is off is one symptom. One other is seeing the handset requesting a PIN code as an alternative of unlocking through Face ID. This alerts that somebody used your iPhone at night time or the cellphone restarted. When the iPhone restarts, it asks on your PIN code earlier than Face ID turns into accessible once more.
As I kind this, I notice that I woke as much as the iPhone requiring my PIN code a number of instances prior to now 12 months. It occurred randomly, and I believed the iPhone simply didn’t register my face correctly.
I didn’t take into account that the handset might need been shutting down and forgot about it. I often set up updates in the course of the day, so the iPhone wouldn’t have restarted for that motive. That’s really the one legitimate excuse for iPhones randomly restarting: Performing an automated iOS replace.
Nonetheless, I haven’t skilled the problem on my iPhone 14 Professional just lately. And I’m working the most recent software program replace, iOS 17.0.3. Hopefully, Apple will repair the shutdown points in some unspecified time in the future within the close to future with its iOS 17.0.4 replace.
