Fixing a Boot Loop:

If it keeps turning on and off, then that would mean that your iPhone is in a Boot Loop. This typically occurs when you go about installing an update, and it stalled while in the process. Use my User Tip: How to Fix an iPhone in a Boot Loop - User Tip

My iphone 11 has a replacement battery.

Now over 7months

Everything worked superfine till now with the update 18.1.1

If it's a Battery problem it's a APPLE update crashed the batterie problem.

One more thing

Batterie status is not to see with replacement Batteries.

Butt with 18.1.1 it worked and showed me 93% Batterie health

After updating to the new iOS 18.1.1 my iPhone ran just like usual, then my battery died, When I tried to charge my iPhone, NOTHING, tried every charger in the house, would not charge. Took it to the Apple store, they couldn't do a thing, ran all kinds of tests, tried resetting it. They couldn't do a thing. This update KILLED my iPhone, making me purchase a new one and because my iPhone was now DEAD I could not exchange it, even thou it's Apple's fault due to their 'System Update.' One of the Apple employees at the store said, "this is off the record & I didn't say this, but yes this has been happening and Apple should replace your phone for free."

it is the IOS 18.1.1 that is causing the shutdowns. I updated my phone yesterday (iphone 11) and today the problem started: it shutdown randomly at least three times. What the **** is going on??

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.

Remember, the right question often leads to the solution!

iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.

Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

Hello~ I can report that iOS 18.1.1 has not caused any battery issues for me… so I don’t find it to be a software issue or we all would have it. I however would not have my battery replaced by anyone but Apple.

Funny how it’s happening to so many people following the 18.1.1 update.

unlikely to be anything but external factors, given it’s happening to so many people after the update.
