iPhone 5 IOS 7 battery dead when really at 29% after taking photos

Yes, I had my battery replaced and now I don't have to charge my phone twice a day. In fact, this new battery has been lasting almost 2 days without charge with the same amount usage. I am, however, still dubious about ios being the culprit. Maybe by the time/if Apple owns up and fixes this issue and offers us all new batteries, mine will be ready to be replaced again. Until then, I will hopefully still be enjoying a battery that doesn't shut off my phone at 30something%. It really is a treat having a new battery and I recommend anyone who has apple care plus(like I do) go take advantage of it.

I also have this same problem on an Iphone 5. Dies around 30%, plug in and it shows around 40%. I was about to order a battery today but think I'll at least wait and see if 7.1 fixes it. I tried doing the full install of 7.0.4 yesterday and it didn't help.

This only started happening after I installed iOS 7. On a side note, the iOS 7 install also bricked my girlfriend's 4S (genius bar claims there must be a bad sector on the phone's flash).

Good day gentlemen!

Mine shuts itself off at the rage of 90% to 20%. It happens more often when I'm on my outdoor activities and temperature is below 0 C. It can be turned on after 30 or so minutes or if you are carrying a portable charger then 5 seconds of charger turns it back to life.

I was thinking of a battery problem and was going to purchase a new one but after reading these posts I started to doubt. Maybe it's an iOS7 issue indeed.

Will be waiting.

Add mine and my wife's 2x iphone 5's to this list. We purchased our phones on the same date, both the same model, same batch and upgraded to ios 7 on the same date. Low and behold we have this battery going flat issue within 2 days of each other ......coincidence?

I posted in another forum, but same thing, this happened after an incremental update to iOS 7 on my iPhone 5. My shutoffs occur anywhere between 30% - 85%. Heck, this morning it shut off at 100%. None of the suggested fixes here, or elsewhere, work. Neither does wiping the phone.

This is very, very similar to the wifi bug in iOS 6, which I naturally had as well, and although Apple never seemed to own up to that, it got fixed with an update and suddenly disappeared. Here's hoping that happens again, but I'm pretty skeptical right now considering Apple seems to feel that (probably) hundreds of people suddenly have faulty batteries, all at the same time.

Hundreds? You mean thousands! Look at how many views this thread has. You should subscribe to this thread and then you can see what people are really saying before the posts get deleted

I'm pretty sure there was a recall on many 5s units for faulty batteries, not sure about the 5 though.

Add me to the list, iPhone 4S running ios 7.0.4, updated couple of days ago, now i shut off at abt 20% consistently...

Add me to the list also. iPhone 4S on 7.0.4. It shuts down about 25-30%, then on plugging it into the mains comes up showing 25% charge. If you try to switch it on after it's died, it comes up with the charging cable symbol but if you leave it about 5 minutes it will switch back on showing 25%. Then die again a few minutes later once you try to actually do anything with the phone. I find google maps kills it instantly at 25% - some use of safari or email it copes with. This started with the ios 7.0.4 update - it was fine before. I've also tried a complete reset and wipe - this fixed it for about 3 days, then it started again.

Do people find this is mainly happening on phones about 1 year old and older. Mine has literally happened 2 weeks out of warranty my wife the same. Luckily have quite a few heavy handed phone calls to t mobile quoting EU consumer goods directive I managed to bag her a brand new iphone 5s 64gb as they did not have any refurb 64gb iphone 5's to replace hers.... RESULT!!

If your still in contract within a 2 year period your service provider is legally required to give you a fix (which they won't as it is apple only) or a free replacement of similar specification. This is down to the EU consumer goods directive and the phone company being the official supplier of the phone and not Apple. The phone companies will Fight it initially but get it escalated to a supervisors/manager quote their legal obligations and eventually you will get a refurb replacement (due to it being an apple product). In our case we were lucky to get a brand new one with one year of apple warranty remaining on it. You really have to stand your ground though as all customer service supervisors are instructed not to give out these replacements willy nilly. Seems like. Lot of companies like to ignore the EU directive until really pushed! HTH some people!

My wife and I are having the exact same issue after we've upgraded our two IPhone5 to iOS7...

My experience with this issue was on 6.1.3, but i overcame this issue by replacing the battery, and over use with different iphone I've got a fair idea of what causes the battery to do this.

Some batteries have a 'memory' and I think it all depends on the kind of battery..

Much like older cellphones, if you unplugged them at half-charged, it would take a TINY amount of the total away from you. Months later, you'd go from 100% lasting 4 days, to 100% lasting 10 hours, and eventually only a few hours, when at that point you'd be heading to a shop to buy a new phone.

I can't confirm that iphones are the same, but i know for a fact that Apple has stated that the batteries have 'cycles'.. Say for example you could only get 100 charges out of an iphone.. The cycles would make it so that it unplugging it at 40% charged wouldnt count as one of those 100 charges.., but only 40% of 1 of those 100 cycles, and then running it to 20% then charging it up again.. You would have used you first cycle at 80% charged as you only had 60% left from that cycle.

If you leave your phone plugged in at 100%, and it continues to charge overnight.. The battery is constantly being drained and charged at the same time..it's using more than 1 cycle, and (back to example of 100 total cycles) effectively cutting the batteries 100(exampled) cycles to as low as only 30 cycles of full charge..
Eventually, towards the end of the batteries cycles.. at around 10cycles left, your batteries memory is so F**ked from the overcharging that it thinks that 30% is actually only 1% and shuts itself down.. later realising that that 30% might actually be 5 percent, so it turns back on and works for another while.. until you start putting battery intensive tasks to it, and it gives up again.

I hope you're following me on this..
I've tried to make it understandable through 3 years of iphones, and my own experience.
It's the same with laptops, in that it's recommended to charge them to full, then run them completely dead.. otherwise 4 months after getting laptop it needs the charger plugged in or dies straight away

Hope this helped anyone understand

No harm in adding my experience to the thread.

Noticed strange battery behaviour since a few weeks, 30% battery gone in 1 night (while sleeping).

Started to turn off celular and wifi every night, that seemed to help.

Now this morning, woke up, iPhone states 8% battery left, plug in the charger and it jumps to 38% immediatly.

Started to doubting myself that it really was 8% so unplugged power cord and it showed 8% again, pfew I'm not mental... Plugged in charger again and then it stayed on 8% and started charging.

Checked back about 15 minutes later, battery already 75% charged, wow that's fast wasn't it 🙂

Unplugged it and left it alone for about 30 minutes, started looking up the problem on the web, ended up here.

Decided to restart my phone, after starting it up again, it now shows 80%, eum... ***...5% free charge !?

Now 5 minutes later 78%.

Will be calling support tomorrow, phone is more then 1 year old but in Belgium we should get 2 year warranty as is it the law, very curious what they will tell me tomorrow.

Edit : iPhone 5, iOS 7.0.4.

Do you have a recommendation on where to get battery replaced, then? I heard this explanation for my iPod years ago, got the battery replaced at a third-party store, and my iPod exploded in my pocket a few months later. Been worried about battery replacement ever since.
