Q: iOS 6.1.3 battery drainage

last night when i went to bed at 12 AM, I had 90% battery. I woke up at 8 AM with 41% battery.

Anyone care to explain why it's draining so much so fast?

I don't use location services, push/fetch are set to manual, even in the advanced settings and I turned off all my apps in the multi tasker.No icloud or anything.

Do I just have a ****** battery? My iphone 4s is over a year old.

My phone barely hits 4 hours of usage of texting, checking mails, using pandora, and browsing safari.

Pandora can be a real battery killer depending on your connection type / speed / quality, it forces the phone maintain a continuous 2 way data connection.

Have you tried a hard reset of the 4S?  It could help reset any stuck or open apps that may be running in the backround.  To reset just hold down the on/off button and the home button at the same time until the Apple logo appears (~10 sec).

I can tell you why. Because iOS 6.1.3 *****. So ill tell you what you do.

1) charge your phone until is "says" full.

2) press the top and home button until it shuts down (Don't unplug the phone leave it plugged in)

3) wait until you see the lock screen and unplug it.

That should make the battery less crazy for a few days. Then it'll start crapping out again.

Apple did this to the iPhone 3G owners before. Their phones were never the same after ios 4.0. Same with us 4s owners.

@Jajaba

1) I'm not find of Samsung. I've never owned a Samsung phone

2) if I wasn't an Apple fan I wouldn't own 2 iPhones and a MacBook would I?

@Xyba25

1) not sure why you're speaking in Thai. I'm not Thai.

2) I really don't care about Android. I want my iphone to not drain in 4 hours that's all.

Now. Get on that guy who keeps saying it's Chrome and get off my back.

There you go OFF Topic again. 

@Jajaba

So. He's been using Pandora all this time without problems. All of a sudden it's Pandora that is the issue?

No. It is iOS. That's the real problem.

Wasn't iOS designed so that no App could drain the battery like that?

@Jajaba

I see. So the guy who spent a whole post insulting me. Was he off topic too or not?

Yup, I tried multiple hard resets still nothing. And the phone drains even if I don't use Pandora. I'll charge it to 100%, go the whole day without using pandora and my battery life will still be gone.

@thai_iphone4, I'll try that and get back to you.

Thanks to both of you.

It's not the Mail app or Push mail. That's not draining your battery.

What is draining your battery is iCloud. Turn it off.

You will also need to follow my steps above to charge the phone and hard rest when it's plugged in. This will take care of iOS 6.1.3 which is incapable of a stable battery reading.

I feel you.

I know it isn't Pandora or anything you are doing. It isn't your fault.

This morning I woke up. It was at 100% full. 5 minutes went down to 99%. Restarted the phone. Came back and it was at 100% again.

So. I did it again.

1) Plugged it in until it showed me the plug as fully charged.

2) pressed the sleep and home button until it shut off. Did NOT unplug it

3) wait until its back to the lock screen. then unplug the phone.

Then it was normal. It took about 15 minutes to go to 99% this time. It is always the same thing.

Also, I just turned off iCloud for the time being because it's eating through my data.  This isn't the issue as you can see though because you don't even had iCloud set up.

Unfortunately for us, all the "fixes" here end up with a hard reset of the phone. But it's not a fix. Slowly but surely the battery life will blow again.

Hey i posted this on another board and it solved their problem so i thought I'd repost!

I had the same problem and tried everything and i found my fix!

Go to settings> privacy> location services> system services

Turn off Cell Network Search! Also turn the rest off  if they aren't necessary.

The cell network search was what did it... I did a little research and it's not necessary.

Hope this helps!

Location services is turned off by default.

Not an issue for the ios 6.1.3 battery drain.

As far as System Location Services, you can turn them all off. Doesn't matter. They're all off by default until you turn it on.

so I did the hard reset thing that you told me and according to my phone's usage 2 hours 17 mins later I'm at 91%

I have 20 minutes of usage logged in. In that 20 mins I probably texted a couple times, used safari for a couple mins and scrolled on Instagram.

I used to be able to go the whole day without needing to charge and now this?

Hi guys,

I have already posted update on using iCloud. For some reason battery was improved - I did nothing to improve situation. My phone is now ok for almost 1.5 day with average usage. I've also stared using twitter. Even this fact has not made any negative impact. So, I believe the issue is with battery's self-calibration. It should addict to your manner of usage. That's what I think and it's just my personal opinion. Please note that I've moved from Android to iOS. Even with the problems I've faced before the battery is much better. So, I would prefer staying with iphone rather going back to android device.
