Phone randomly shuts off and won't turn on past logo

Have you tried charging it wirelessly? Your battery is at End of Life or near EOL if you haven’t replaced it. An EOL battery explains the random shut offs and inability to turn on and shutting down at logo. Resetting cannot restore an EOL battery.

Apple will need to do diagnostics and replace the battery.

You need to have Apple perform diagnostics on your iPhone. It can be done in person at an Apple Retail Store or at an Apple Authorized Service Provider. You can also contact Apple Support and request remote diagnostics.

Looks like the battery was totally dead.

Apple said they fixed this in iOS 27, what a shame.

Connect the iPhone to the charger.If this doesn't work, please replug and unplug it repeatedly and replace various different chargers.

It is not guaranteed to save your iPhone unless you have the ability to take apart the iPhone and charge the battery directly.

⚠️Caution: Since Apple does not provide a repair manual for iPhone 11, be sure that you or the repairer has enough experience in repairing Apple devices.

I remember that since the iPhone6 or iPhone7 (Apple gradually abandoned Sony lithium-ion battery cell), if the battery is deeply discharged, the battery logic board will disconnect the circuit to protect the battery. If the battery is deeply discharged for several years, the battery of these devices will be completely damaged and even bulged.

But you're right. The description in the release notes is not for the situation of "logos appearing".

When was the last time that you had the battery replaced on your iPhone?

I believe you may be referring to the issue that affected iPhone 17 devices and was fixed in iOS 26.5.1. It is reported here:

• This update addresses an issue for a small number of users that may prevent wired charging on iPhone Air and iPhone 17 models when the battery is nearly drained.

Since the tagline for the OP is showing an iPhone 11 with iOS 18, that is irrelevant.

Well,I don’t think so.

Resolved Issues

• Fixed: Devices with a deeply discharged battery might fail to boot into the OS and remain stuck on the red dead battery icon screen indefinitely until the device is rebooted or the power adapter is unplugged and reconnected. (177346712)

Be careful with references to iOS beta versions discussion. Per the terms and conditions for testing beta releases they are not to be discussed in the Apple Communities at any time. If the moderators see this they’ll delete the post. Sorry. Just an FYI. 😃
