iPhone 5 short battery life?

To auto check you in when you arrive.

Ditto to all of the new iPhone 5 owners who are wondering why we have to change settings on everything just to get the same battery life we had with our iPhone 4s! Why disable some of the new features or cut the brightness? What's the point the in upgrading if you can't use the phone without quickly running out of battery life!

Anyone used SYS Activity Manager for their iphone 5? The application tab always has a few applications running even though i remove all the apps. The apps that are always running in the background are, mail, camera, app store and phone. Is this normal?

Anyway i tried the DFU restore and i set it as a new phone. The battery didnt drain that much on standby but when i turn on to whatsapp, the battery starts to drain like1% in 2mins. I dont think this is normal.

Yesterday at the same time, with similar amount of usage, battery was 23% as of 1500, +0800 GMT

Reset settings this morning, full charge, similar usage ==>56% at 1500 hrs

When I'm using the phone, the battery meter starts dropping fast. If I don't touch it, all's good.

On my Iphone4, it would be around 75% at this time. So still disappointing battery performance, but at least looks like one charge will last me till the end of the workday.

i have the same problem too. If it is on standby its all good. When it is in use, it drops 1% per minute.

My iPhone 5 certainly doesn't seem as bad as the rest of people who have posted, however I'm not convinced its better or even equally matched to the iPhone 4, I'd say its not as good at holding charge and the battery performance is to be fair a little worrying but I'm certainly not prepared to re-install or get a new phone, its just not bad enough to warrant the hassle, I can live with it until hopefully a new iOS comes along. But I would urge ANYONE who is suffering poor battery performance (worse than mine) to phone Apple immediately.. The more people report there issues to APPLE customer services the quicker it will be resolved. There has been some great information posted here initially but posting here now to say you have bad battery performance will not solve the issue.

There has been many people who seem to have great knowledge of the workings of the iPhone and how to maximise its performance in settings etc. and real problem solvers. These people for their best efforts have admitted nothing seems to really work.

So for all of us, PLEASE REPORT TO APPLE!

Best of luck!

Been advised this morning my an Apple customer care advisor to do a DFU reset (or the Trot Nixon as its now known, lol) and left that doing on my lunch break. Once it finished i didnt do a restore of anykind, downloaded a few apps (literally two) over Wi-Fi and that was it. Unplugged it and went back to work.

finished work and checked my iPhone 5 and the battery had already got down to 80% within 5.5 hours?! it'd been sat next to my MacBook doing nothing except on standby.

I called Apple customer care back with my case number from this morning. I was on the call for just under 5 minutes with my headset and i watched the percentage go from 78% to 74% within the time of the call and mentioned it to the guy at Apple everytime it dropped. to say he was surprised would be an understatement.

Genius Appointment arranged for friday morning at my closest Apple store. I just hope they can get it sorted. I'm actually one of the few people that need my iPhone as a phone. so if i cant use app for fear of the battery running out i might as well go back to a Nokia 3210 😟

I had the same issue with brand new iPhone 5. As suggested elsewhere, I turned off send diagnostics and usage, and went from losing 2% every 5 minutes to losing 40% in 12 hours.

I made no other changes, and used the phone in exactly the same manner.

Much better now...

Hi,

We r pretty much in the same boat. I live in Ottawa, I did pretty much the same restore as you last evening so we will see today if it is all better.

I too believe it is a software issue.

Fingers crossed.

She wouldnt lie to you, would she?

First of all, let me quash these rumors right here, right now. I was on the phone with an Apple senior advisor tonight and she not only forwarded my screenshots and reports to the engineering team but told me you guys are severely mistake and that the senior teams and engineers absolutely read these forums and are quite aware of the battery draining issues and the WiFi issues we are having.

As I mentioned previously there is a bug I'd like all of you to check on that I discovered and to call Apple and email a senior advisor your screenshots so he or she can forward them to the engineering department as well.

Go to the Settings app.

Then click on Usage.

Then click on Cellular usage at the bottom of the page.

Take a look at your tether info.

If you are like me, you have never tethered before but even if you have you should likely encounter this same bug.

Your tether sent data might say some gargantuan number or it might say 0 bytes or 1.0Kb.

Click on Reset Statistics.

Your tether sent data might now change to 124TB, 126TB, null (EB), or -36473200000000... Every time you hit reset statistics it will likely change to some ridiculous amount.

Your received data might also change to 860MB which mine seemed to do once, but most commonly it was the sent tether data which kept changing to some crazy number.

Then click back on the Usage arrow at the top left hand corner, then scroll down back to Cellular usage, repeat the Reset Statistics button pressing and take your screen shots in rapid succession of doing this each time. You take screenshots by clicking down the power button and home buttons simultaneously.

Also it said my lifetime cellular usage was 2 days and 16 hours which is pretty absurd considering I don't think I ever put 64 hours of talk time on my iPhone 4S that I had for 11 months, let alone the iPhone 5 which I've only had for a few days.

This is just yet another bug that may or may not be linked to the battery draining issue. When you call in you must ask for a Senior Advisor. They are the only ones who can forward your report to the engineering team and will give you their email for you to send the screenshots. They will also likely send you a text message containing a link which will take you to an internal iOS page that authorizes you to send them your battery diagnostic data. I strongly urge you to do all of this to help them to get us an iOS update as soon as possible.

I went through the entire process of not only resetting all my settings (which did not help) but started from scratch, using no backup, erasing everything on my iPhone 5 and re-entering all my info manually and re-downloading all my apps. At first I thought it helped because it stayed on 100% for ten minutes, but then started dropping again 1% every two minutes while in use. The battery drainage seems to only be at its worst when WiFi is enabled. You might also notice that web pages don't always load or that the iTunes Store says "Sorry, cannot connect right now." You might also notice your processor speed is sometimes blazing fast and other times slower than the iPhone 4S. These are all things you should inform your senior advisor of. But they are reading this. It will help expedite the process though if you call them and send them your screen shots. We all want a fix sooner than later.

Hopefully this has been a helpful and informative post and I appreciate you reading it.

Thanks.

Thanks! Very useful info. I just checked and my Lifetime talk time is 28 days!! Quite ridiculous. I don't seem to have tether stats on my cellular usage screen though, is this because I'm not in the US?

Pretty busy at work so will call my local Apple tech support later in the week.

Btw, end of the day on minimal usage (just a few calls and texts and surfing/music during the work commute) and I'm at 23% as of 2000 hrs +08GMT. Still disappointing but better than yesterday (I reset settings this morning)

Hey,

I have the same issue. Runnign SYS Activity manager, seems like there is way too much system memory being used all the time. I am sure this is the issue for the battery draining so fast, especially when using apps. On WiFi i get decent battery life but on cellular it is pretty bad.

I have doen a full restore as well.

I called Apple to report the issue, I hope they come up with at fix soon. I would suggest everyone call and report this issue so it can get sorted out sooner reather than later!

Cheers,

M

Hi mikgab, I'm in Ottawa as well (Carp) and was wondering if you bought your iP5 at Best Buy on Kanata like I did.
