Why is my iPhone5 battery draining so fast, worse than my iphone4?

There is solution for battery draining.

I have replaced my iPhone 5 32gb 2 times now so using my third unit typing this and battery dropped from 40% to 38% now. I have tested ALL "fixes" there is out there on all my three units but the problem is persistent (37%) and I really do not know what to do.

On the first unit I updated to 6.0.2

Second unit was running 6.0.1 and I didn't update to se if the problem persisted and it did.

Third unit was running 6.0 and I didn't update to see if the problem persisted and it did.

I have done all kind of resets, restores (36%), calibrating etc etc etc and still same problem. Now my patients has ran out and the people at the Apple Genius Bar will have to deal with a very unhappy customer.

I have used iPhone since the first model and this is by far the worst iPhone I have owned. Not just that, the (35%) housing of the phone doesn't take anything. Even the smallest thing with the lightest touch will put scratches on it.

Really bad Apple, really BAD!!!!

You must type really slow! I had my iphone 5 replaced and the battery is perfect. I have no Bluetooth on but everything else pretty much normal. Don't insult my iphone and call her bad! And don't you ever call apple bad! ;) lol

Thanks for the helpful answer! I'm happy for you, and give my best to your girlfriend Siri to I didn't mean to offend her!

No problem! Happy to help! And I will. Siri forgives you :) (your lucky this time she can get angry.)

iPhone 5, 32GB, iOS 6.0.1

I've monitored the usage.

WIFI is able to reach 8 hours and above upon usage.

However, the biggest issue here is 3G.

3G usage tested, 1% decrease every 2 minute usage, that means browsing FB / Safari. In this case, I can only benefit 3 hours of usage on 3G when my battery reach 15-20%. On paper, it was 8 hours on 3G.

In addition, during standby with 3G enable, 1% decrease every 9 minute.

*Please note that i have none iCloud account, location services off, notification off, no Navigation use during the testing period. Plainly just whatsapp, instagram, FB, Safari, Summly*

Me and two of my collegues are experienceing exactly the same thing.

As mentioned earlier i have replaced my iPhone unit 2 times and the third time i sat down with a person at the Genious bar and tested the phone side to side with a iPhone 4 and once on the 3G network min drain 3 times faster than his iPhone 4 that was 2 years old.

The we did the test side by side with one of the workers iPhone 5 and after 10 min usage i the guy at the Genious bar replied " I havnt really though of it but it seems that mine has the same issue, the battery is pretty bad" 🙂

So in the end they just said that i probably should wait of the next iOS update and see it it gets better, if not i should come back.

Lets pray is the iOS issue and next update will get this 3G battery drain issue fix, otherwise I don't think the apple will recall and replace a new for us, since the stock is getting so limited and I doubt they will have a new unit made from factory to replace with us.
Thanks for the response ChrisApple81.

Ever since I've turned off some of the system services under privacy>location services> system services I've been getting about 9 hours of usage time. Pretty heavy usage. Of Facebook messaging browsing the web. Some of the services are useless for me. So I turned them off. Hopefully it works for someone else. Try it out.

Thanks!!! DOMINGUEZ619. U fixed my battery!!! Wow to think it was that simple all along. Thx again!

No problem. Glad I could help.

So i just wanted to update on what ha happend.

I got my iPhone 5 replaced fot the 3rd time yesterday, the guys at the Genious Bar are the best, headup to them. They did a systemcheck and battery showed up beeing fine, however the statistics showed 0 usage (verry odd)

So for this unit is beahving quite ok compared to my previous ones.

This is how i did it.

1. Set it up as a new phone in iTunes.

2. Updated to iOS 6.1

3. Restored from my most recent backup from the previous phone.

4. Charged it up to 100%.

This is the performance after the first Charge.

Now the phone is at 9%

Standby: 20 Hours, 40 Minutes

Usage: 6 Hours, 50 Minutes (Spotify, Some video, Gaming, Facebook and webbrowsing)

Talktime: 1 Hour, 35 Minutes

Data: Sent: 3.8Mb and Received 154Mb

My previous phones would have been dead less then a third of these numbers. I will update if i see any improvements from now on.

I had an I phone 4 that one day just started losing battery very quickly. I just replaced it with an I phone 5 and it is doing the same thing. I am so confused now by so many complaints about the same thing. I know one other person that is having problems. I have 2 weeks to return and am thinking maybe I should trade it back in. Any suggestions for a better alternative?? I can't even keep it charged for 10 hrs not even using it!

I had a similar situation and i bought a mophie air. Works great and it doubles battery. Not exaggurating.

Brightness on an iPhone is known to drain battery life. It will drain a lot quicker with it all the way up, will drop half as much with it half way, and so on. I always have the brightness on my iPhone 5 all the way down unless I am outside, in the sun. Phone lasts me maybe 12+ hours, depending on how much I use it. Try turning the brightness all the way down and see if you see a change? Also, turn locations off, turn Wi-Fi off when you're out and about, close all background apps if you aren't using them, and disable Push for emails. I have Push enabled but that is entirely up to you. Hope this helped.
