    I have been having extremely poor battery life with my iPhone 5 recently, and it will shut down at around 50% battery, because it says that the battery is dead. I then try to to turn the phone back on, but it shows the connect to power source screen. I then try turning it on again, and it turns on and says that there is a fifty percent charge. Other times, the battery will deplete very quickly (with very little use). I am out of warranty, and am wondering about any fixes for this problem. I am also not in the market for a new iPhone.

    Thanks In Advance

    Sounds like you may have a battery problem. Did you recently update your OS?

    You could try restoring it and setting up as a new phone. It might help if it's a software issue. Otherwise you may be looking at a new battery. There seems to be a common issue with the iPhone 5 battery.

    Incidentally, since iOS 7.0 my phone would often shut down at up to 24%. When it comes back on, it still thinks it's at 24%, or wherever it was when it shut off.

    Thanks, and I did recently update my phone, but the battery issue started a few days afterwards. Also, how much is a iPhone battery to replace myself, and how much will Apple charge to replace it.

    Thanks

    As far as Apple goes: https://www.apple.com/batteries/replacements.html

    just curious...what kind of case do you use ?

    the reason i ask is bc i was using a life proof case and having same overheating issues after the update.

    A few days afterwards is still awfully suspicious. I'd still go through a full restore to factory new and see if it helps before spending money on it.

    I've had similar situations happen but not with so much battery... it was around 10%, I believe.

    If a battery recalibration doesn't work - let phone drain until it powers off. Charge to 100% over night without interruption - Then take it to an Apple Store to have the battery tested and replaced. Under Apple Care this is free. Outside of Apple Care it is/was about $79 and takes about 10 mins not including wait time for your appointment.

    Same issue with my wife's iPhone 5 on 7.1. Battery drains incredibly fast, and will frequently shut off anywhere between 30-45% then when it's plugged in the phone turns on and shows battery at 30% or higher. Nothing running in the background, location services turned off, etc.

    Prior to updating to ios 7, there were none of these problems and the phone would regularly last 2 days without a charge on moderate use.

    We've done all the calibration tips, restoring, etc. Nothing helps. Not worth bringing to Apple and paying $80 for a new battery (no Apple Care) when she has an upgrade available soon and will use it on the iPhone 6 whenever that comes out. So for now she just travels with a charger wherever she goes.

    Sad but true

    Are they actually replacing batteries in-house now? Or just swapping phones?

    It would be nice if they're replacing batteries because this would save you from having to do a full restore.

    They've been doing in-house battery swaps since at least October 2013. My battery was shot (within warranty) and they replaced the battery in about an hour. They had a few batteries ahead of me, otherwise it's a 20 minute job.

    I've had odd battery behavior in my iPhone 5 lately too. It'll jump down in % anywhere from 10 to 15% and if I plug it in, it'll jump up 10 to 15% instantaneously!

    That and I've had such poor performance of late. I'm on 7.0.4. I get usually around 2 to 3.5 hours max now, but the battery does charge quickly!

    These problems sound like the battery developing high internal resistance. When this happens, the voltage may be normal at low load, but when the load increases (as in, the phone transmits a lot of data to the tower) the voltage can drop below the cutoff causing it to shut down.

    Once the phone is off, the voltage rises above the cutoff again, and you can turn it on again. Rinse. Repeat.

    In layman's terms, the battery is boned. Get it swapped. :)

    ----------

    Yep, same thing here. The battery meter is partially based on voltage, so if the battery's internal resistance is high, charging it will make the voltage spike more than it normally does.

    Layman's terms again: Battery boned. Swap. :)

    Similar to mine. Mine shuts down only at cold weather when I use it outside(20s to 30s F)

    This is a sign of battery failure, most likely one of the cells has gone bad. I had the same issue in 3 of my families 4 (launch day)-Iphone 5s. I got all of mine replaced at the Apple store under the Applecare warranty. If you are out of warranty they will replace it for $80 in about 30 minutes. When I took mine in, they gave me a url to run an in-store test on my battery and all three phones indicated failure.

    Since replacing it back in November, I have not seen any of the large battery percentage jumps like the many have mentioned, but I did get them constantly before I had it replaced. As many other threads on here will state, they think it is an iOS7 bug, it is not. Apple had a lot of crappy batteries installed in the iPhone5 and neglected to let anyone know about.

    So go get your battery replaced and you will be a happy camper.
    ....And just in case, do an Itunes backup before you go. One of the batteries they were replacing broke a connector on the phones logic board, and they just replaced the phone for free. An hour later I had the "new" phone restored, and all was good.

    Both my wife's iphone 5 & mine were having the same problem. I bought a couple of mophie cases for the same price as having both batteries replaced. Today my phone was at about 60%, I took some pics & turned the display off. About 15 minutes later I opened the phone again & the battery went to 11%, I turned the case on & the battery went right to 70%. Kind of a pain, but I think the cases will get us to the iphone 6 this fall.
