Q: After upgrading to iOS 9.2, I have no service and my battery is draining quickly

I have an iPhone 6S. I live in the UK.

 

I upgraded to iOS 9.2 two days ago, and have seen two problems since:

 

  1. I cannot get any mobile service. I see "No Service" in the top left of the home screen when I try to search for service. Wi-fi still works fine. I turned my phone off and on again, and while it does find service briefly, it quickly goes back to "No Service". I tried going into the Mobile Carrier area of Settings and turning off the various options, then back on again. Nothing has worked.
  2. My battery is draining very quickly. It is 14:12 in the afternoon and I currently have 29% battery. Usually I haven't dipped below 60% when I get home at 17:00, as I do not use my phone very heavily. The Gmail app has taken up 35% of my battery life despite only spending 9 minutes on screen. My phone is warmer than it would normally be.

 

I have heard that when a mobile phone searches for service repeatedly, this uses a lot of battery. This phone has been set to Aeroplane Mode + Wi-fi since this morning - I have not had it searching for service at any point today.

 

People have recommended Resetting my settings, but I do not know what this will do to my phone, so I haven't touched it, especially since every time someone suggests this, it doesn't work for the afflicted person.

 

Is there anywhere I can check to see bug reports with the 9.2 release? I feel like there's an issue with it but I'm not seeing anything on the internet to suggest that.

iPhone 6s, iOS 9.2, null

A:

I've kept my phone on Airplane Mode for the majority of time since this problem first happened, which means that it's not searching for service, and the battery still drains. The phone also runs warmer than normal, which I wouldn't expect simply from searching for service.

 

And I made sure to see what happened with the service after doing the restore, and BEFORE restoring the backup I made (A fresh iPhone, essentially), and it still had the same problem.

 

But it's no matter - I've contacted Apple Support as Tj13Parker suggested, and their best guess is that it's a hardware issue. It looks like I'll be getting the phone replaced at some point.

 

You've been very helpful, AmishCake! Having someone doubt me at every step certainly helps to get one's thoughts in order!

    I have ordered the new SIM from my carrier (GiffGaff), and am waiting for it to arrive.


    However, yesterday (The "faulty" SIM is still in my phone), I turned Airplane Mode off on my phone, and noticed that it finds a network, listed as "O2-UK".

     

    Also, the battery is not draining as quickly as it was previously, nor is it always running as hot.

     

    O2 is the network through which "Giffgaff" operates, but before I experienced the problems outlined in this thread my network indicator would say "giffgaff", not "O2-UK".

     

    Whenever I could get my phone to find signal, for however briefly, after I upgraded, the network indicator would also say "giffgaff". So it's strange that it now appears to be working but is showing the wrong network.

     

    If I switch to Airplane Mode and then back again, sometimes I will see "No service" after the iPhone searches for a while, and sometimes it will find "O2-UK". Overall I'd say the signal/service is less reliable.

     

    This can all still be explained by a faulty SIM, I suspect, but I just wanted to list all of the symptoms I'm currently seeing since it seems strange for the phone to have gotten better, but not fixed itself entirely.

    For the record, my problem was fixed after Apple replaced the phone for me.

     

    However, your problem may be slightly different (toliapos' problem was slightly different from mine, for example).

    As I said in my previous post, the problem was only fixed for me by Apple replacing the iPhone completely.

    Hi,

     

    I dont suppose anyone has any solutions for my iPhone 5.

     

    I update it to 9.2 and it also says no service. I'm in the UK too.

     

    I have had iPhones since they first came out and this update has made me rethink my position. I called into a apple store and their solutions was spend £600 on a new phone. I feel particularly aggrieved as my phone was fully working prior to the update. Any one got any help or advice that might help other than move over to Android!

    This is clearly an iOS 9.2 issue.  Multiple sim cards and restoring the phone won't fix this.  Anyone with this issue on ios 9.2, download ios 9.3 beta 2 and try the fix.  I skipped 9.2 entirely and went from 9.1 to 9.3 from seeing this issue so many times.

     

    So download the beta ios 9.3 beta 2 to see if we can fix this software issue.

     

    Get back with me.

     

    THANK YOU
