Ever since updating to iOS 26, my iphone 14 keeps restarting. Before today, the problem was fixed by updating all the apps, in between restarts. But today, all the apps are updated, and it still keeps restarting. What is happening here?
iPhone 14, iOS 26
The first suspect is the battery. After that, it's the power supply section or "motherboard". Will the phone stay on long enough for you to check the battery settings?
Settings > Battery > Battery Health & Charging
What reading do you see for Maximum Capacity?

It's getting down there, and there may be some other things going on that the user settings cannot read.
Make an appointment at the Apple Store / Genius Bar or take the phone to an authorized Apple service shop to let them check and test the battery.
You can find a list of authorized shops in your area using this link: Find Locations
The tech can also check the power supply board or motherboard to look for an "iffy" component. Hopefully, it is not a board issue, since that is an expensive fix, unless you still have AppleCare+ in effect.
“It really feels like an iOS problem, because it started the day that I updated to iOS 26, stopped once all apps were updated, and then reoccurred with the next iOS update.”

Getting Out of this Boot Loop;
Seems to me it is stuck in a Boot Loop; this typically occurs when you go about performing an update, and it stalls while in the process. Use my User Tip: How to Fix an iPhone in a Boot Loop - User Tip
Lmao, this is amazing. They told me the logic board had to be replaced. They didn't have one, so I had to send phone in to Apple. They sent a loaner phone. So, while the old phone kept restarting, I tried to get the loaner phone cloned to the old one. But it wouldn't work because phone kept restarting. Finally I gave up on that method, and just decided to backup the loaner phone from icloud. But, Apple sent me a phone running iOS 18, so it wouldn't work. So I updated the entire operating system, and then deleted the old phone, and mailed it to Apple. Now, it seems there's no easy way to get this loaner phone to have all of my stuff (that I'm paying a monthly fee to be held in the cloud), photos, apps, settings, whatever.
The problem was non-existent for the last two weeks, and then started again last night. Updated a ton of apps, restarts keep happening. All possible updates are done, restarts keep happening. What is happening???

'Tis a shame, if they never looked into this being a Boot Loop. I don't see why it wouldn't have fixed it.
Next time, back up your info prior to sending it in --particularly to iCloud.
"A boot loop is a symptom.....not a cause. Most of the time, the real cause is bad hardware, as it was in this case as well."

Apple sends them a new phone --maybe they did consider it --I wouldn't know --but why all the send ins, and a failed :"loaner iPhone"?
Shows 84% as Maximum Capacity
What did the technician say when you took the phone in for diagnostics?
I didn't take it in because 1) closest is 30 min away, 2) the constant restarting ended, and it wouldn't make sense to me that a battery problem would end, and then restart two weeks later.
It really feels like an iOS problem, because it started the day that I updated to iOS 26, stopped once all apps were updated, and then reoccurred with the next iOS update.
Well I'm not surprised that there was an iOS update two days ago, and now my phone keeps restarting while I frantically try to update apps (despite having auto updates turned on) in between restarts.
Let us know what the technician says when you do decide to take the phone in for a diagnostic check.
A boot loop is a symptom.....not a cause. Almost always, the real cause is bad hardware, as it was in this case as well.
That's why the tech found a bad motherboard.
Why does my phone keep restarting?
