I think that it's different for different people. I've tried all the fixes (including putting the phone into Recovery Mode, wiping it and re-doing it as a new phone) with no luck. I think my problem is related to the screen. If I just listen to music with everything on (3G/Wi-Fi, etc) I usually don't get a substantial drop. The second the screen is on - even if I'm just reading a book in airplane mode - the percentage gauge comes tumbling down like the prices in that Walmart ad with the smiley face
Can't believe nothing has been done to correct this. I was one of those that was doing battery logging for them but then heard nothing again. It got better at one point then went downhill again. Have now sold my 4S after the third replacement and bought an LG Google Nexus, which whilst still isn't marvellous on battery, is better than I was getting from each of my 4S replacements At this rate, my iPad 3 has fair cause to be hiding in the corner of the room shaking with fear as it has the same drain issues. The experience with lack of admission of an issue and members of Apple store staff repeatedly looking at me like I'm imagining it and that "nobody else has mentioned it" has really put me off what I used to think was a premium service as well as product. I can't complain at replacements, but there was no fix.
I know that this is unhelpful and more of a rant, but if they actually said there was an issue - with it in mind that as heavy users we know when a product isn't performing as it was before - then I would have had a lot more patience.
To be turning off all the features to maintain battery (when we never used to) is an unacceptable fix on a handset in this price range - and one that in my case made little difference to the drain anyway.
Ok so I thought I'd provide my updated battery performance checks with new (faulty) 6.01:
Iphone 4S 6.0.1
No location services
- 6.00am 100%
- 7.00 84%
- 9.30 47%
- 10.00 33%
- 11.00 16%
- 11.30 10%
- 12.15pm 0%
So the battery drained from 100% in 6hours 15 mins. During that time I made and received NO CALLS. Only got one SMS. pretty much everything was turned off (as you can see). Only 3G & wifi left on.
Thats woeful. Previsouly I was geting up to 2 days on 5.x with pretty much every feature enabled.
I Am now retesting with:
Facebook Integration disabled
Facebook logged out
Facebook app deleted
I'll let you know if that makes any difference tommorrow
Since Apple doesn't seem to bother.
Found the solution...
Sell iPhone 4 (still worth a lot second hand) and buy world best mobile phone according to some
Samsung Galaxy S3
So whenever this happens to me, as I have mentioned in this forum, it is a background process leftover from an app. In my case it is always Skype, but others have reported different apps. Restarting is not sufficient, since restoring from backup causes the background processes to be restarted. The only solution is to double-click to bring up the 'recent applications' at the bottom, then kill all of them to get rid of residual background processes. This always works for me.
For me Skype has been a battery killer since 6.0.1 There is some kind of incompatibility with 6.0.1 (and maybe 6.0). It used to work fine in 5.x.
With Facebook off and DELETED from the phone battery life is still the same. Max of 5-6 hours on standby.
No calls in or out.
This is woeful.
Just saw a post from someone that said you can improve battery life by TURNING OFF CELLULAR DATA.
That's has to be joke right?
Turn a smartphone into a dumb phone?
The only point of this thing is that it can receive cellular data.
Without that you might as well have a 20 dollar brick phone.
We have 5 IOS device on our house.
The 3 devices (2 iPhones and 1 ipad) upgraded to IOS 6 have this problem.
The 2 iPhones still on IOS5 have no issues.
Pretty clear to me.
I HAD the same problems with my wifes 4s. I finally did the Restore. I actually don't think any of these issues were the problem, although I did remove Safari from the bar and install chrome. But I did notice that her phone was always on the home screen whenver I'd check it. I thought hmm, why isn't it auto locking...because that is turned off. I activated the lock feature and now the pbone is nice and cool and the battery isn't dead after a day...in fact it's been three hours and only lost like three percent...
just my experience. Glad to have this almost fixed for her..tired of her telling me her phone died again after a few hours..
Did the full restore as new phone on my 4S
Didnt transfer any settings
Reinstalled existing applications.
Charged to 100% from wall.
Battery life still as woeful as ever.
2 4S phones in the house upgraded to IOS6 - both less than 6 hours battery life ON STANDBY
2 4S NOT upgraded - still get 24+ hours on standby
Optimize Your Settings
Depending on how they are configured, a few features may decrease your iPhone battery life. For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iOS 5.0 or later and may help extend your battery life.
- Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness & Wallpaper and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness & Wallpaper and set Auto-Brightness to On.
- Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
- Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
- Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and disable notifications for select applications. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
- Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > Privacy > Location Services or use location services only when needed.
- Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
