Have strange bug on iPhone 4s (bug type 110)

I want to give as much detail as I can, because I feel that I've been stuck with this for a week now, and I don't know what to do.

I have an iPhone 4s running iOS 8.1.2

This phone was my brothers for about 1 and a half or so, and I've now had it for about 4 months (so it's safe to assume it's out of warranty). Had no problems with it at all. Neither of us had.

I've never dropped my phone, never put it in water, never done anything wrong with it. But early last week my Phone crashed (turned itself off). I thought maybe I was using it too much, and had too many apps open. So I put it down for the night. The next day, I turned it on and the Apple logo cam up as normal, but it shut itself off. Then it tried to turn itself on again (back to the Apple logo screen).

I didn't know what was going on, so I plugged it into my iTunes. It was fixed (or so I thought). It turned on. Great!. Later that day, it happened again, it crashed (turned itself off). But it was worse. It was stuck in this loop for a while. So I plugged it into my iTunes again but it didn't work. I restored my iPhone back to iOS 8.1.2 and restored all my content.

This has happened a few times now, and I'm sick of trying to fix it.

I found a diagnostic log. Here it is (in its entirety):

(Wow. that was a pain to type out.)

Since I've restored my iPhone a few times, I doubt the problem is to do with the software. (Unless it's to do with 8.1.2)

I don't know.

Anyway, any help would be great. Would love to know what is happening, why and what I can do.

Thanks guys.

(P.S Why don't apple have an email to contact?)

(P.S.S I hope none of that information in the diagnostics is personal.)

(P.S.S.S Don't know if this is the best category to put this. Didn't know where else to go)

iPhone 4S, iOS 8.1.2

I assume everybody has lost interest, but that's okay. I'm still going to keep everyone updated in case someone has the same issue and stumbles upon this.

So I went to Ireland's version of an Apple store. Not helpful. Told me to update to iOS 8.1.3 and that they don't do repairs there.

So I'm going to update my phone now and I'll post again later

That's good to know. I'll go in to the closest store when I get a chance this week

It often occurs after a do it yourself battery replacement and has to do with a temperature warning system for battery overheating. Call AppleCare and see if there is an Apple Authorized Service Provider that works on iPhones.

In the meantime try putting it in DFU mode (Google it for helpful YouTube videos) and Restore it in iTunes. Might try it a few times.

It also occurs on an older battery if it is failing or that sensor is failed. It just gets triggered more often during a battery replacement.

Did you put the phone in DFU mode before any of these Restores?

I'm pretty sure I did. I did it the same every time? (I did the one where the iTunes logo appears with the USB cable below it)

Will putting it into DFU mode make any difference?

Sounds like you put it in Recovery Mode. DFU mode is a little bit higher level and removes everything from the phone. Give it a shot.

Okay cool. I'll try it now.

Because the problem I have occurs (what seems to be) randomly, I won't know if it's going to help until a little later tomorrow maybe.

Do you think this will solve the problem? If it's hardware problem, this shouldn't make a difference, right?

Some have reported after leaving the phone alone for a day and doing the DFU restore it worked. It is worth the effort as it is no cost to you. If it doesn't work go the hardware repair route.

Oh wow really? Would love to see where you've seen that. That would be perfect. Seems almost too good to be true 🙂

It's been 5 days and my phone hasn't crashed once, so I think it's safe to assume the problems solved 🙂

I was lucky to get the bug 2 days before the new software update was released.

For anyone looking back on this thread looking for a solution, just make sure your iTunes and your iPhone are on the latest software

Bye guys 🙂

Bug Type 110 is a hardware error. It has nothing to do with DIY battery replacements or a previously replaced battery. You need to get your phone replaced.

I also had bug_type 110 and 115 often. About two months ago the phone suddenly was off when I pulled it out of my pocket. At first it seemed to happen when it was in my pocket, but slowly got worse, to the point where it would reboot sometimes in my hand, and then sometimes over and over and over again. It got to the point where it needed to be plugged in most of the time and would only work unplugged for a short while - not liking to be moved much.

Apple Genus told me, "...yeah, it's over three years old, sometimes things just do that...... the diagnostics says there is nothing wrong" and reloaded from scratch and sent me on my way.

I had my iPhone5 battery replaced over a year ago under the replacement program, so I didn't suspect it at first as prior to the first event, it held a charge fairly well.

After a lot of diagnosing I took a risk and cracked open my iPhone and dropped a new battery into the unit. So far, after 24hrs, the unit is working great, no power offs, no reboots, and is behaving very much like it did months ago.

I hope this helps....
