System time (Clock) changes on iPhone 5c

Set it up as new device again, this time without using any backup afterwards and don't install any 3rd party apps as well.

If the time will not be changed after that, the backup contained corrupt files, causing this behavior.

Try to install 3rd party apps and see if the problem comes back, since you can't use the backup, you'll have to start without any app data.

If still not luck, contact Apple Support or the carrier to get it checked.

I have got exactly the same problems for both wifi (poor performance and always discount) and time (stop running when the phone is in stand-by) after upgrading my iPhone 5c to the buggy 8.1.2!

I have visited Apple Store, they have done all the restore and diagnostics which could not fix it. Their solution is asking me to replace the phone for ~US$300 (out of warranty).

With so many users having the same issue, I don't believe it is a hardware fault and goes wrong at the same time.

My iphone 5c approximately the same age (7 days over manufacturer's warranty, naturally ) & same buggy/crappy operating system and I too am having the same exact problem & tried the same setting adjustments, etc as described in the original post. Nothing has worked. I haven't had a bit of trouble with this phone until that last 'upgrade' and ever since I 'upgraded' all sorts of glitches started popping up; however, this is the only one I haven't been able to correct. I've already taken it to the Carrier (AT&T) and their geniuses were clueless & couldn't figure it out. I've tried everything recommended in these community posts & nothing has worked for more than a couple of minutes. COME ON APPLE! There's too many people having the same problem and the common denominater is this piece of crap phone. Really **** poor customer support when your geniuses can't fix them either. Fix them our replace them. You've certainly made enough money on these phones to not support them any better than this. Very dissatisfied with the phone, the carrier and especially with Apple total lack of support on their high price/no service products.

When suggesting 'set up as new device', I assume that means to erase all the data & settings, etc. and restore the backup?!?

Exact same issue here right down to the full reset will fix the time for only 5-10min then bang....random time again even if i never restore the device..... The only other thing for me is that the Bluetooth will no longer turn on. Wifi seams to be OK.

With the time being off the iMessages will not go through most of the time.

Have you had any luck yet?

PS i had hoped that the iOS 8.2 would fix it...but no. I had to get my wife a new phone because it is now more or less useless.

exact same issue here.

isn't it strange that apple is totally silent on this issue? are they waiting to be sure that 100% of the iphone 5c's are effected, to take the blame and start a replacement program?

No.

Likely they are seeing if it really is an issue at all and if so, is it the 5c only, and how large of an issue it is.

This is the first I have heard of it.

Well ****, this is interesting. I can tell you exactly when this happened was Sunday morning Daylight savings time. My Automatic set option was not set, and wen the times switched, bingo. all of this happened and with exactly the same results, same issues. this is a firmware glitched caused by this download. We need a repair from the technical support

Exactly the same issue here, I've tried everything and still no luck. The phone is out of warrantee but I am booking it into an apple store to see if they can resolve.

"This is the first I have heard of it."

just a simple google search would show that this is not the only case or the only thread. i also see many things for the first time but do not prefer to claim that it is the only one.

what happened at the store? any good news?

DDon't turn ur head to this apple

I never wrote it wasn't an issue Brianjoh84 are you blind?

I have a 5c from Verizon and have had the same issues. First, the clock and bluetooth and then texts and calls weren't working. Verizon was no help and told me I could buy a used phone until my upgrade and I haven't tried the genius bar yet because I'm expecting the same answer. I ended up downgrading to an old 4 until my upgrade in September which ***** because it's so slow! haha

Anyone get this problem resolved?
