- Here is what to do
if your iPhone keeps restarting.
If it's currently stuck in that restart loop, hard reset.
If you have an iPhone 8 or newer,
quickly press and release the volume up button,
quickly press and release the volume down button,
then press and hold the side button
till the screen goes black and the Apple logo appears.
If you got iPhone 7 or 7 plus,
it is the volume down button and the power button.
Press and hold those simultaneously
until screen goes black and the Apple logo appears.
If you have an iPhone Success or older,
it is the home button and the power button,
press and hold them simultaneously.
Once your iPhone is out of that restart loop,
it's very important to back it up immediately.
- Yeah, because you don't know when it's gonna happen again.
So iCloud is your best bet.
If you can't use iCloud for or whatever reason,
use a computer, and David will tell you what versions
- The Mac running Mac OS 10.15 or newer, you'll use Finder.
If you have a PC or a Mac running 10.14 or older,
you'll use iTunes.
Next, check for an iOS update.
So I'm gonna open up settings, scroll down and tab general.
Then tap software update.
If an update's available, tap download, and install.
- IOS updates fix software problems
that are kind of significant like this,
that can cause an iPhone to restart.
Wouldn't be the first time a software update fixes problem,
so do it.
It's not a bad idea.
- It's also possible that an app
is making your iPhone restart.
So to look for a really bad app, we're gonna go back
to the main page of settings, scroll down and tap privacy,
scroll down and tap analytics and improvements,
then tap analytics data.
Once you're here, start scrolling through this list
of things you don't recognize
and look for the name of a specific app
over and over and over again.
One or two references, fine.
But if it's a lot of references,
then there might be an issue.
- There might be.
Usually, these logs indicate a problem
where the app just crashes.
You end up back on the home screen,
but there could be a bigger problem.
David's phone was too healthy
to be able to demo this at all.
But for me, chess, there's just a lot of chesses.
- A lot of chess.
- Yep, I think it's chess.
- So if you see something like this,
check for an app update or delete
and reinstall the app to see if that fixes the issue,
but it's really unlikely.
- It's unlikely unless it always happens
when you're using a specific app.
- Sure.
Next up check battery health.
- Right.
Your battery, if it's damaged in some way
will cause your iPhone to suddenly turn off
and then back on again.
So it keeps restarting, suddenly dies, comes back on,
check out battery health.
- If you're on the main page of the settings app,
scroll down and tap battery, then tap battery health.
- Well, I guess you're doing okay.
- 100% capacity, peak performance capability.
We're doing all right over here.
- Yeah, you're doing great.
And even if it's like 70 or 60, it's probably not a problem.
It's just that if it's 20 or 15 or if it's way lower
than it should be like it's a new phone and it's 60-
- might be an issue.
- might be a problem. - If you got a new phone
and it has 60% maximum battery capacity,
reach out to Apple for a new phone.
- Yeah, a new phone.
- A refund.
Next try removing and reinserting the SIM card.
Sometimes your iPhone will restart
because it's having an issue connecting
to your carrier's wireless network.
- That's for sure.
If you have an iPhone 12 or newer or an iPhone 8 or older,
you're gonna look at the left side of your phone
for the SIM tray.
If you're anywhere in the middle,
the middle child, they're usually forgotten, right side.
- Press that SIM card ejector tool
right into that small SIM card tray hole.
- Boom.
- [David] Pop it over.
Take it out.
- Is that the first time I call it tray hole? All right.
So SIM card, the modem of an iPhone is very important.
And if the SIM card is screwed up,
sometimes it will cause the whole phone to crash
and then reboot.
- If you don't have a SIM card ejector tool
and we wouldn't blame you for not having one of those,
grab paperclips, straighten it out, stick it in.

Next step, we're going to reset all settings.
- All right, resetting all settings
resets all the settings on your phone,
but it can solve these kinds of problems.
- Let's go back to the main page of the settings app,
scroll up and tap general.
Then scroll down to transfer or reset iPhone.
Tap on that.
Tap reset, tap reset all settings.
All the settings in your iPhone reset to factory defaults
that includes your Bluetooth devices,
your WiFi passwords, your wallpaper.
- It's a pain in the butt.
But it's easier than our next step.
- Which is to DFU restore your iPhone.
- Right, back it up first to iCloud, iTunes.
I think we already said that.
- We already did that.
- And in case you skipped forward in the video,
back it up then watch one of our videos

As you said, back up your iPhone,
if you didn't do it at the begin, fine.
If you don't do it before you do a DFU restore,
- Don't blame us.
- don't blame us 'cause we told you twice
- Count 'em.
- So that was thrice, right there.
- If your iPhone is still restarting over and over
