iPhone 5 battery life is way worse than iPhone 4

I just got an iphone 5 and I restored a backup from my iPhone 4 so I have the same settings. But the iphone 5 drains way faster than my two year old very well used iPhone 4 which is running 5.1.1. Is it because of IOS 6? Just leaving it sitting overnight lost about half the battery. My iPhone 4 hardly uses any battery while it sits overnight.


Or do I have a bad battery on my new phone?

I came across this thread: https://discussions.apple.com/thread/4907710?start=0&tstart=0


The "fix" described in that thread is not terribly invasive or difficult (although many of my email accounts would not turn off and stay off, requiring several reboots). I can't swear yet that this method works, but I've been off the charger for nearly a full day and still have 67% battery left, and the usage meter says 3 hours and 34 minutes (mostly wifi, but some 4G/LTE).


Post replies to this thread if you try this method...

Had the same problem of battery drain with my new iphone 5 , updated to 6.1.3. Could see the battery dropping fast every 5 mins.This is on day 1 of the purchase.

Have been going thru the fixes mentioned in MANY of the posts available.


My 2 cents on the subject :

1) Reset the network settings

2) Fully discharged the battery and did a full recharge to 100%


Got thru the day without having to recharge.

Got 14Hr 30 Mins from a full charge along with 1 Hr 45 Mins of Google Maps usage which used up 40% of battery.


This is without using 3G, I'm sure it will drain the battery faster.

That's good but my iPhone losses more than that just on standby and to top things off the sounds broken now and I've tried everything that's meant to sort it out and it hasn't so I'm going to have to get it replaced however I'm at my holiday home and the nearest apple store is 3hrs

Hi all


Re Iphone 5 battery issue - My latest experience


I tried many things posted all over th net to resolve my battery problem. I thaught I had resolved it but last week I was in London and by 2 pm my battery was down to 25%. I walked into the covent garden Apple store. I waited one hour to see one of their experts. He tested the phone and said there is a fault with the battery. He gave me a new one on the spot and since then it has been perfect, I get 2 days of heavy use.


My conclusion is that , simply, they have an issue with the Iphone 5 battery

Not necessarily, all I am stating is my experience. I can see that many have the same problem and I suspect that they ciould have had a batch of batterries from a dodgy supplier.


A battery drain resulting in the phone not lasting 1.5 to 2 days is abnormal. The suggestions I have seen to tun this and that off are silly. Yes if you turn the phone off it will last a long time.


Based on my experience I would recommend all that have a problem to go to an Apple Store if they can or get the phone exchanged under warranty until they get one with a battery that works.

This is indeed the last apple product I will buy. I love the iphone 5. But what is the point without a battery. I'm seriously thinking a out relegating the 5 for home wifi use and go purchase a galaxy or android for out and about. I'm tired of monitoring the battery, tired of walking with extra batteries and just win disappointed. May Steve Jobs rest in peace. All his hard work is being undone by incompetence.

Yeah I've booked a opointment for tomorrow to see what they can do but how can they be able to make a iPad that lasts about 3-4days with 100% but a iPhone can't even keep that in 3-4 hours. For the price pay for the phone it's self and what you get for you money is terrible my contract will finish at £900 Bering in mind it only coasts aplle about £17 to make the phone

I tried this (even posted about it myself not realizing we were posting the same thing) and must say, it seemed to work for a few days, but I'm right back to where I started. I get almost 50% less battery life on wifi than I did before updating to 3.1.2. and 3.1.3 and overall my iPhone 5 gets no where near to the battery life Apple claims in its ads and on its website.


This is very frustrating and disappointing...
