iOS 6 iPhone 4s battery drain

You're are getting to the essence. As is the person who sarcastically, but truly recommended deleting all ones' apps. Think about it. It's not rocket surgery. :-) iclouds, location services, push notifications, dropboxes, email, etc. every app that needs or is allowed to communicate with it's mother ship has to use cellular or wifi (or both for some GPS) - which are the major power burners - is going to drain your battery.

Especially when you first launch stuff too, like iCloud or Dropbox. They have to upload or download gazzillions of bytes until they can get to the incremental backup stages.

You want to keep the batt life up - then cut back on all the data going in & out (up/down if you prefer) to those apps which are really useful all day (and spread it out) or those you can turn on when you need them.

It sounds good to have 15 apps that know where you are and are telling all your friends while keeping your email, backup, and such in sync to the second. It's makes for a bunch of power hungry little monsters.

I think the biggest problem with this whole mess is that it's not a single issue so no single fix. For some it's mail, for others it's exchange, and others something else entirely.

Like I said before in another post mine is perfect now after downgrading the firmware on my netgear router.

I can't say why this worked because my wife's iphone which is the exact same model and with the same 6.1.3 software and settings was fine. Mine however kept switching between wifi and 3G every 10 seconds or less. When I was home all day, the battery would drain from 100% to 20% in less than a day.

Now mine, just like my wife's can go an entire day and evening on standby and stay above 90%. With a couple of calls and 20 minutes of app or web use It still stays above 80% after a whole day.

No a reset, is when you hold down the home/power button together until you see the apple logo and then release, then wait for the phone to boot back up.

disabling siri seemed to have a big improvement for me

Same issue here, I think it's Siri, I have turned it off and it has improved a lot.

I've disabled location services and it's stopped draining... Can anyone else confirm?

About the CPU usage in 80% anytime, I´ve turned off Siri and I´ve reseted and now the CPU usage is Ok, about 5-10%

TURN OFF LOCATION SETTINGS!!! My phone was hot chewing batt power turned off location and batt power is probably better than before Io6

I reset my iphone, then did a restore from backup and battery seems to be at or above than before the update to iOS 6. I will continue to check.

Hello! Same happened to me, i disabled Maps From Location Services and at least it got way better.

I had the same problem and turned off 'Shared Photo Stream' recharged my battery and have been running at 100% battery life do the past 40 minutes!!

I hope it's that splenic a fix!!

Good luck

Search there if your curious as to which apps are crashing and any memory issues.

Hey there,

I HAD THIS PROBLEM AND FIXED IT. it's simple. Do a backup and restore via iTunes. battery life is now better than IOS 5.

Just do it.

I had the same issue with iPhone 4S. Disabling of 3G helped to recover normal battery consumption.

I managed to fix my battery draining problem. The only thing I did was switch Bluetooth off and it is now back to its normal usage. Hope this works for others.
