Is iOS 6 draining iPhone 4 battery faster?

Can someone with the drain issue try to reset network settings?

This worked for me on a 3GS and on a 4 several month ago after an update of IOS.

source of this tipp

you will have to enter WIFI passwords and so on afterwards.

I've gone back to ios 5.1.1 with my iphone 4. Not worth all the hassle with the upgrade for me. Too many things were missing and I think you need a 4s to get the benefit og ios 6.

Ok, there is what I have tried.

• Full factory reset
• Let the battery completely empty and then did a full recharge.
• Mobile Data (Cellular Data) off
• Turned all mail to fetch only
• Turned off all but Messages, Calls and Calendar in Notifaction Center
• Turned everything off in spotlight (doubt this is the problem)
• Location Services Off
• iCloud on for Contacts, Calendar, Notes and Find my Phone (but with Location Services off this seems a little daft).
• Facetime off

08.09 - 100% Full charge and unplugged over night was still 100%.

09.29 - 90%

12.21 - 80%

Not great, made a few calls, listened to a few hours of music (nothing new). Will slowly turn features back on to find the misbehaving beasty!

Tempted to do a back and restore using iTunes. Has anyone tried this?

I think it's not same for everyone. I've updated mine 4s to IOS 6 on wednesday and no problems whatsoever. Using phone all day at work and had to plug in as usual at night. No difference on battery usage at all.

I am having significant change in Batt drain. Maps suck, no street view, ugly redesign of some native iPhone apps. Very disappointed. RIP Steve, it's all downhill from here!

Having same problem. I updated my iphone4 to IOS6 last night. Had been charging phone, went to bed last night with phone at 100%. Wifi off, BT on, no other apps running. Woke up this morning it was at 87% without any usage at all. Normally it will still be at 100%. Just minimal usage this morning (no calls, no apps, no internet, just browsing settings on phone) and it has already dropped to 83%. Not good! Hope I can roll back.

My battery life *****! I would go 2 to 2 1/2 days without charging and now I cannot make it a whole day! How can we fix this? I have and iphone 4s, it is only 7 months old. Ugh,

Well, on a good note, at least if your Iphone dies all the time it will limit the chances of you driving into a river using their new maps software. But, yes same issue as everyone is having. At some point, in turning off all these services to get an 8 hour battery life, doesn't it just make sence to but a $30 throw away phone. You are getting just about the same amount of features.

I thought I remember stupidity being defined as repeating an action over and over with the same negative outcome. You link I would be smart enough to know to wait a bit to upgrade. I was excited to Facetime with family over cellular, until I then found out I needed to pay more $$$ per month to do it, even with an unlimited data plan.

Go Apple!!!

mine too at 7amm it was 100% then at 9 it was only 30% ...what can i do ??????

If i have to off my Notification and Location service then why the **** to use Iphone...

until the exact culprite is found, I suggest you do the following

• Full factory reset
• Let the battery completely empty and then did a full recharge.
• Mobile Data (Cellular Data) off
• Turned all mail to fetch only
• Turned off all but Messages, Calls and Calendar in Notifaction Center
• Turned everything off in spotlight (doubt this is the problem)
• Location Services Off
• iCloud on for Contacts, Calendar, Notes and Find my Phone (but with Location Services off this seems a little daft).
• Facetime off

Here's how my battery has done with about 2 hours talk time and listening to much (and little else)

08.09 - 100% Full charge and unplugged over night was still 100%.

09.29 - 90%

12.21 - 80%

14.27 - 60%

Not great but some what better.

I did the above 9/20/12 and battery life has returned to normal.

Hope this helps ya'll!

I noticed that using wifi instead of 4g uses more charge & my onavo says maps is the second largest data consumer (behind Facebook) but the problem is I'm not using maps, it's not even open. What gives? Lost 10% in 40 minutes doing nothing out of the ordinary.

Also did the network reset, turned off just about everything I could think of & lowered Briteness also ;/ I live in SF sounds like its time to report this to the media, maybe apple will get the idea that they need to stop blocking downgrades when stuff like this happens. Went through this last time with antennagate.

I'm really considering the galaxy 3.

Hey AbacusPete,

Trying your suggestions plus the folowing

• Just did a full backup and restore.
• Turned mobile data (Cellular data) back on
• Turned spotlight searched back on

Just re-syncing all the applications (*yawn*) and then will see how the battery life is.
