Q: iPhone 5 with iOS 7 randomly shuts off

Add me to the list, I have the phone for 1 year, and the problems started like 1 month ago, I noticed the phone will shut off when I was taking the pictures, even at 65% battery, I called Apple and got a replacement phone, but the replacement has exactly the same problem! going to call them again today!

Holy smokes!!! 76,000 views now!! It was only like 2000 when I posted about a month ago. Clearly there is a true problem here.

To the people who had this problem and replaced their battery.

Is the problem completely fixed now?

I'm still only having fast drops when I'm using LTE or the camera when the percent it below 50. It's like the OS goes nuts and doesn't calculate the drain properly. And it shut off at 15%. Powered back on then it shutdown immediately when it got to the lockscreen. If I'm on wifi it's a different story. Works fine drains to zero and I still have. Decent battery life. For some reason it doesn't like LTE or using the camera with lower capacity left. Checked my battery with I backup bot and it's still at 1280 mAH after 440 cycles. My i4 has 748 cycles and still showing 1332 mAH and it runs fine with no shut offs.

I've also noticed that it only drains rapidly and shuts down when I'm on (Verizon) LTE. And the Facebook app also seems to drain the battery extremely fast while on LTE.

Yes with replacement the problem is resolved (at least in my case).

(but i have another 5, and i am not going to pay for it anymore).

Two weeks since I replaced the defective battery on my iPhone 5. Still running the latest version of iOS-7 and not a single shutdown of my phone.

Bottom-line: replacing the defective battery eliminated the random shutdowns. My iPhone 5 is operating as expected while still running iOS 7.0.4.

Add my iPhone 4S to those having the sudden drain/shutdown issue.   Last night with about 50% charge, I took two photos.  The iPhone immediately shut down.   When I pressed the Sleep/Wake button, I got the large Battery Charge needed icon which showed about 1% or so of charge.

I then connected my iPhone to my charger, and within minutes it showed 78% charge.   I honestly don't think the OS has any clue what the actual charge is.   I only upgraded to iOS 7 recently, and never had this problem with iOS 6.

Ad me to the list.. I have an Iphone 4 and when I updated to the 7.0.4.. It started shutdown randomly.. until the point it can't be unplugged.. I tried the reinstalation, fromat and firmware update.. and Nothing.. The only thing that keeps it from shutdown (when it isn't plugged to a power source/computer) is, putting it in air plane mode (no wifi, no 3G, no connection)... I can watch videos, take photos and hear music.. for as long as a day.. So it is a software problem.. But.. i will try the battery replacement soon to see if that works... because i can't live without data..

Ditto to the battery/power management issue. On iPhone 4s + ios7.0.4 (11B554a). Seems to happen directly after taking a pic and the phone is already down to 35%-50% power. Not had many completely random shutdowns yet though.

Looks like I get asserts - seen in my General -> About -> Diagnostics & Usage -> Diagnostic & Usage Data

I have the same problem with a 1.5 yr old iphone 5. The problem started before I upgraded to IOS7, though. And I got a replacement battery yesterday, for me it didn't solve the problem at all. The shutdowns are maybe less frequent, but they still happen. And the battery percentage is "frozen", both when I charge the phone and when I use it. When I reboot it, the battery percentage can change from 100% to 20% all of a sudden.

For me, I think the only solution is to get an entirely new phone. There seems to be something really wrong in the communication between the software and the battery, because the battery itself definitely wasn't the problem in my case.

Come on Apple,

Stop using your once loyal users as your unpaid R&D developers.

It's just lazy and poor business on your part....

hey everyone, i have this issue too and saw this post which aparently helped solve the problem for some other person. im just wondering if anyone here has seen this and/ or tried it? i might later this weekend or next week but if anyone else has tried these steps and would like to save me the trouble......

That's basically whst I did except leaving the phone off for an hour.

It has shutdown once early at 6% but, it does seem better than before the complete restore.

That's done it! It'll shutdown now!

so it worked? should i attempt this?

Same deal here.  The phone doesn't actually shut down 100%:

If I'm on a phone call it does not drop the call, but I can't hear the person and they can hear me for about 15 seconds until the phone finishes it's 1/2 reboot.

I exchanged my phone for a new one (sure it was refurbished) and now the new one has the same problem.

Restoring the phone as new isn't doing the trick.

ios7 strikes, again, me thinks.

Has this continued to work for you?

I'm having the same problem as so many others: the phone doesn't actually shut down 100%.

For example, if I'm on a phone call it does not drop the call, but I can't hear the person and they can hear me for about 15 seconds until the phone finishes it's 1/2 reboot.
