Q: iOS 6 iPhone 4s battery drain

This one works for me: In Settings>iCloud, turn all to "off" except Note and remeinders.

In Settings>Mail, Contacts, Calendars>iCloud, put "off" all except Reminders and Notes and Find My Iphone (Mail and Calendar MUST be turned Off).

In Setting>Mail, Contacts, Calendar>Exchange, put them all off except calendar (for google mail calendar)

In Setting>Mail, Contacts, Calendar>(Your default mail), Put off Contacts and Calendar except Notes

In these settings, you still have in icloud the reminder and notes and Gmail Calendar sync

Remove your mail from notifications

Also a big problem of battery drain and an important consumption of datas. Very frustrated...

Really frustrated. Today the bateery drain even faster. From 45 % --> 32% in few minutes of safari browsing. whats going on?

Yesterday 17 Out

Hello. I solved the batery drain problem...restoring the iphone to factory settings anda clean of data, sync my contacts and don't install any old application, only new facebook, full charge the batery and use it normally with mobile data on but 3g off and it dies before one day and a half, yssterday i full charge before died and unplugged at 5pm with 100% batery and mobile data off today at 5pm have 70% batery...i'm waiting to see when we dies, but seems he is now ok...and o makes drain is old applications...

Today 18 Out

At this time my iphone 4 don't died yet, and have 22% of batery and 2 daya(48hours) and 3 hours...i think i solve the problem it is the old applications who are not compatible

Last night I charged my phone to 100% right before I went to bed. My phone was in Do Not Disturb while I was asleep. I woke up to 87% battery life. My fetch was set to "manual" and "push" was off. iCloud was on though. I'm convinced it's the culprit. I received a newly replaced iPhone 4S about two weeks ago and they installed iOS 6 from iTunes. I setup my phone as "new" and there are very few applications on my phone. My phone battery is draining as fast as my confidence in Apple's ability to acknowlege and resolve this issue.

Here is how I fixed mine.

1.  Installed Google Chrome

2.  Went to Settings > General > Restrictions > set security Key > Disabled Safari

3.  Closed out of settings

4.  Held down the top button and the center round button to hard shutdown the phone.

5.  After phone restarted from hard shutdown my battery automatically restored

The problem is in safari... I also got a bill that showed massive amount of data useage.

My battery life is amazing after this.

This has worked on all my co-workers Iphones at work.  Google chrome stinks as it does not fully integrate into ios6 but it gets the job done until apple gets it together and fixes this problem.

With your amazing battery life, was your LTE or 4G or 3G switched ON? Or was it OFF and you are on EDGE or 2G connection that's why you guys are having good battery life?

I'm sure some of u may know that LTE, 4G, 3G, consumes **** allot of power and EDGE/2G are the least. I switch OFF 3G and let it run on EDGE. I only use 3G when I'm browsing the web or downloading. I had a full charged 100% and unplug the charger at 715am and the time now is 12pm and my phone is still at 100% with light usage of SMS and checking update on websites.

iPhons 4S

turn off 3G/4G/LTE only use it when nessesary like browsing, downloading

turn off set auto time

turn off icloud except for find my iphone

turn off auto backup to icloud

turn off push email switch to manual

this is what i got with Edge connection. full charged at 715am

Safari (I believe) is the significant factor!

I closed down the pages I had open, have not even bothered to disable it, and my phone which was running flat in 4.5hours is now:-

USAGE : 3hours 18 minutes

Standby: 2 Days, 12 Hours

And I still have 25% battery life left!

Battery life seems better than ever now!

updated my iphone about 2 weeks ago only this week i have noticed that i am having to charge it every few hours where as my battery would last a whole day with wifi and 3g on.... now i have to have wifi and 3g turned off.i have tried turning app notifications off and also turning location services off and still no joy.all apps are closed down as 3g and wifi off and my battery is still losing charge about 10% every hour when im not on it and this is much more when i have wifi or 3g on please help

Very simple solution for battery drainage; it works for me on iphone 4.

Just reboot the device i.e.

- Held down the top button and the center round button to hard shutdown the phone

- After phone restarted from hard shutdown my battery automatically restored

All battery problems solved.........):):

I've tried about everything as well except setting it up as a new phone.  With System Activity Monitor, it appears the issue--at least on my phone--is related to Safari and iCloud syncing.  If I don't use Safari and have iCloud bookmark syncing off, battery usage approaches normal under 5.1.1.
