Messages app freezes every time iPhone 13 charges overnight

Have this exact issue also. only temporarily resolved by restarting iPhone 13 Pro.

Always associated with charging. Only messages app. Charge by USB.

my iCloud backup is under 10GB and messages in iCloud is quite small (3.2GB) as I tend to delete old messages. Hopefully apple fixes this in an update I it’s a nuisance to setup from scratch again. I would do this if I could be guaranteed of it fixing the issue.

I didn’t get a chance to post or mess around with this over the holiday weekend, but the issue came back the next morning after my last post.

At that point, I left Messages in iCloud disabled because I didn’t have time to deal with the issue over the weekend. As expected, I had zero issues.

I called Apple Support and the first tech ran me through the basics which we have all tried here, plus having me disable iMessage and FaceTime in their respective sub menus under Settings. They also checked my addresses against my Apple ID address. I told the tech about this thread and showed him while I was screen sharing. At that point he said “I found it”. When I asked what he found, he said the issue of Messages screen turning white or black when charging on 15.1.1. This was promising! He next said I needed to be assisted by a senior “specialist” (not the exact title he used, but senior *something*). I was then transferred to the senior specialist and she said she wants me to erase my phone and set up as a new phone. Balloon deflated.

I didn’t have the time for that tonight so she is going to call me tomorrow afternoon. Way more time than I want to spend on this, but it is what it is. I did ask about having to wait for 24 hours for the issue to resurface and she didn’t seem to think that would be necessary. We’ll see.

More to come tomorrow.

Also - I mostly use the 5W Apple USB Power Adapter with an Apple Lightning cable. Other than the USB hub in my car, the only other power adapter I have used is an Apple 10W USB adapter from the older iPads. No third party power adapters or cables.

So yesterday I took the leap and my phone was backed up, erased and set up as a new phone. No restore was performed, it's as if it were brand new. 25 hours later and we're still in good shape when I plug in the device. The phone did not backup to iCloud last night though. The manual backup I did before erasing is still the latest backup. All iCloud data is back on the device - messages (back to 2015 with attachments), photos, files, notes, calendar - everything.

Erasing the phone before unpairing my watch prevented my eSIM in the watch to be setup during the re-pairing, so I had to call AT&T to re-provision the SIM in my watch.

On a positive note, the phone is snappy and works very well! Of course there are only stock apps on it...

I'll provide another update tomorrow.

72 hours later, everything is still good. I am confident enough that I am starting to re-personalize my phone again.

The net-net of erasing and starting as new appears to be just losing my apps. Everything else is as it was.

You could backup your phone to a computer to separate from iCloud and try starting from new. This way, if you run into any trouble, you can always go back from a local copy that you have control over. Just a thought.

Good luck my friend. I’ll pop back in if anything goes sideways on my end.

This happens to me as well.!

At first I thought “focus” was the issue as it started to happen when I used my sleep focus overnight, however I turned that option off and it continued to happen every morning when I wake up.

I’ve come formed it doesn’t just happen over night.. it seems to happen when it’s on charge for long periods of time or when on fast charging for short periods of time (I wonder if it triggers when it gets heated up 🤷🏻‍♂️)

Turning it off and on again seems to fix the issue or letting it cool down (normally an hour or so after taking it off charge) works.

It’s super weird that hardware action can trigger a software glitch 🤔

I too wouldn’t get my messages overnight however my iPad (on iPad OS 15) would get the messages. I’m updating the iPad now to latest version (which my iPhone 13 pro is on) and I’ll see if the issue messages stop showing up on the iPad

Anyways, I suppose there may be an update that addresses this soon.. fingers crossed. It’s quite inconvenient be annoying

Same issue here, with all of the same symptoms: icloud backup sizes increased 5x all of a sudden, messages app freezes power cycle needed, icloud messages turned itself off, previous icloud account mismatch error. I first noticed this problem when i migrated from a shared icloud storage plan to an individual one - could’ve been a coincidence, but did anybody else experience this? I also have an iPad on the same icloud account that is working flawlessly with icloud messages turned on.

15.2 also appears to have fixed it for me. i also got a new iphone 13 pro max and upgraded it to 15.2 and restored from my old phone’s backup and haven’t had any issues with the new phone.

As you noticed, I still have something funny going on with icloud backup sizes. my old phone is still backing up 10’s of GB, while my new phone is only backing up 2-3GB. i’m trading the old phone in, so not too concerned with it, but frustrating that this issue in icloud still persists. my ipad on the same icloud account also still has very large backup sizes.
